Necessarily each subject was only briefly +touched upon, but the study is of so enticing a character that 'appetite +grows by feeding,' and the students of the 'Out-door World,' having +tasted the sweetness of companionship with Nature, will not rest +satisfied with the help afforded by that handbook. Each one will want to +go deeper into that particular department which most appeals to his own +inclinations. + +The present volume is written expressly for those who desire to extend +their knowledge of the British Lepidoptera, or, to use the more popular +names, 'Butterflies and Moths.' + +The general characteristics of this interesting order of insects are +described somewhat fully, but, of course, it would be impossible to give +an individual account of all the British Lepidoptera in a work of this +size, so a selection has been made such as will satisfy the requirements +of the great majority of those who intend to take up this particular +branch of entomology. The number of British Butterflies, however, is +so limited that a place has been found for a figure and a description of +every species; and, of the larger moths, many of the common and typical +kinds have been included. An introduction to the study of the +Micro-lepidoptera has also been added. + +No trouble has been spared to render this work thoroughly practical. In +addition to the verbal descriptions of so many species, twelve coloured +plates and a large number of woodcuts have been specially prepared to +help the student in his work. It is believed that the extreme care with +which these have been produced will render them of the greatest +assistance to the collector in the recognition of his specimens. + +But he has not only to recognise his specimens--he must first catch +them; and here full directions have been given to insure success in this +part of his work, as well as in the management, preservation, and +arrangement of his captures. + +The Author hopes that this volume may be the means of adding many happy +hours--hours of the purest enjoyment--to the lives of those whom he has +succeeded in luring into the fields and lanes and woods of the Out-door +World. + + +CONTENTS + + PART I + + _STRUCTURE AND LIFE HISTORY OF THE LEPIDOPTERA_ + + CHAP.

AURELLA--ENLARGED 307 + + + + +PART I + +STRUCTURE AND LIFE-HISTORY OF THE LEPIDOPTERA + +CHAPTER I + +_GENERAL CHARACTERS_ + + +The word _Lepidoptera_, which you see at the head of this page, is the +name of the order of insects to which this volume is to be devoted. It +is formed from two Greek words, one (_lepis_) signifying a _scale_, and +the other (_pteron_) denoting a _wing_; and was applied by the great +naturalist Linnæus to the scaly-winged insects popularly known as +Butterflies and Moths. + +[Illustration: FIG. 1.--SCALES FROM THE WINGS OF BUTTERFLIES.] + +Every one of my readers has undoubtedly handled some of the interesting +creatures of this group--having been led to do so either by the extreme +beauty of their clothing, or, perhaps, from a murderous intent in order +to protect his own garments from the ravages of a supposed marauder. A +light mealy powder will probably have been observed afterwards on the +fingers that have touched the victim's wings. + +This powder, although it sometimes presents a beautiful glossy surface +when spread over the skin, does not exhibit any definite form or +structure without a more minute examination. Yet these are the scales +that led the immortal naturalist to invent the somewhat long but useful +term _Lepidoptera_. + +The very next time the opportunity offers itself, dust off a little of +the mealy powder with a small and very soft brush on to a strip of white +paper or a slip of glass, and examine it with a powerful lens or the low +power of a compound microscope. What a sight you will then behold! Each +little particle of dust is a beautifully formed scale, stamped with a +number of minute rounded projections, and often displaying the most +gorgeous colours. A great variety of designs and tints are often +exhibited by the 'dust' from a single wing. Take, for instance, for your +inspection, scales from the wing of one of our commonest insects, the +Small Tortoiseshell Butterfly (Plate III), and you will be surprised at +the pleasing contrasts. But when your curiosity leads you to deal with +others in the same manner, the varied display of forms and colours is +simply amazing. + +[Illustration: FIG. 2.--PORTION OF THE WING OF A BUTTERFLY FROM WHICH +SOME OF THE SCALES HAVE BEEN REMOVED.] + +In order that we may learn still more of the structure of the wings of +the _Lepidoptera_, we will examine a portion of one from which some of +the scales have been removed, again bringing the lens or the microscope +into our service. We now see that the scales are arranged in rows with +great regularity on a thin and transparent membrane, which is supported +by a system of branching rays. And the membrane itself, in parts which +have been laid bare, is marked with regular rows of dots--the points at +which the scales were originally attached by means of short hollow rods. + +The framework that supports the thin membrane we have spoken of as +consisting of a system of _rays_, but to these the terms _veins_, +_nerves_, _nervures_, or _nervules_ are more commonly applied by various +naturalists. We cannot do better, however, than adhere to the name +originally used, for the structures in question do not perform the +functions of veins, though at first they contain blood, nor are they +themselves parts of the nervous systems of the insects to which they +belong. + +The result of our examination of the wings of butterflies and moths has +been to justify the application of the term _Lepidoptera_; but we must +now study other equally important and interesting features of the +structure of these insects. First, let us note the general form of the +body. + +[Illustration: FIG. 3.--BODY OF A BUTTERFLY--UNDER SIDE. + +1-7, segments of the abdomen; 8, anal extremity; _a_, antennæ; _b_, +tarsus; _c_, tibia; _d_, femur; _e_, palpi; _f_, head; _g_, thorax.] + +A cursory glance at this portion of the creature's anatomy will show +that it consists of three distinct and well-defined parts. In front +there is the head, the size of which is somewhat small in proportion. +Two very large eyes make up the greater portion of its bulk. It is +remarkable, too, that butterflies possess eyes proportionately much +larger than those of moths. Now, since butterflies always fly by day, +and moths are, generally speaking, nocturnal insects, we might be led to +suppose that the reverse of this arrangement would have suited the +creatures better; for a small eye, we should think, would be able to +collect sufficient light in the daytime to form a bright image, and a +larger light-receiving area would be necessary during the darker hours +for the same purpose. But it is evident that the sense of vision must +depend on other conditions besides the size of the eye; and as these +conditions are not understood in relation to the eyes of insects, any +attempt at an explanation would be quite useless. + +The eye of a butterfly or moth is worthy of a closer examination, for it +is a most beautiful and marvellous structure. The outer globular +transparent membrane--the _cornea_--is divided into a large number of +minute polygonal _facets_, each one of which admits light into a small +conical compartment surrounded by a coloured membrane, and supplied with +a fibre of the nerve of vision (the _optic_ nerve). Hence the eye is +often spoken of as _compound_. + +If you look closely into the eyes of various butterflies and moths you +will generally see a ground colour of grey, blue, brown, or black; but +when viewed at certain angles in a strong light the most gorgeous hues +of metallic brilliancy--gold, copper, and bronze--are to be observed. +All such colours are due to the reflection of light from the colouring +matter that lies between the numerous conical compartments. + +[Illustration: FIG. 4.--SECTION OF THE EYE OF AN INSECT.] + +A glance at the section of a compound eye will show you that all the +little cones radiate from a common centre. And, as each little +compartment is surrounded by opaque colouring matter, it is clear that +perpendicular rays only are capable of penetrating to its base and +exciting the nerve fibre that lies there. Thus each little division of a +compound eye forms its own image of the object that happens to be +exactly opposite its facet. But how many facets do we find in a single +eye? Sometimes only a few hundreds, but sometimes as many as seventeen +or eighteen thousand! We must not, however, conclude that the nature of +the vision of butterflies and moths is necessarily very different from +our own. We have two eyes, but the images formed by them are both +blended, so that we do not see double. We can understand, therefore, +that the thousands of images formed in a single eye may be blended +together so as to form one continuous picture. Still there remains this +difference: while in our own case the two images formed by the two eyes +are practically the same, in the case of insects every one of the little +conical tubes of a compound eye forms an image of an object that cannot +possibly be formed by any one of the others. Thus, if the lepidopterous +insect sees a continuous picture of its surroundings, such a picture is +produced by the overlapping and blending, at their edges, of hundreds or +thousands of distinct parts. + +There is yet another interesting difference between the vision of these +insects and that of ourselves. As already stated, our two eyes are both +turned toward the same point at the same time. But look at the +butterfly's eyes. Here are no movable eyeballs, and the two eyes, placed +as they are at the _sides_ of the head, are always turned in _opposite_ +directions. The corneæ, too, are very convex; and consequently the range +of vision is vastly wider than ours. A boy is often easily surprised by +a playmate who approaches him stealthily from behind, but did you ever +try the same game with a butterfly? I have, many a time. After getting +cautiously so near to a butterfly at rest as to be able to distinguish +between its head and its hinder extremity, I have quietly circled round +it so as to approach it from behind, being at the time under the +impression that it wouldn't see me under those circumstances. But not +the slightest advantage did I derive from this stratagem, for the +position and construction of its eyes enabled it to see almost all ways +at once. + +In addition to the two compound eyes, the _Lepidoptera_, or at least +most of them, are provided with two small simple eyes; but these are +generally so hidden among the closely set hair that covers the head, +that it is doubtful whether they are of much service as organs of +vision. + +[Illustration: FIG. 5.--ANTENNÆ OF BUTTERFLIES.] + +[Illustration: FIG. 6.--ANTENNÆ OF MOTHS.] + +The antennæ proceed from two points close to the upper borders of the +eyes. They are jointed organs, and are of very different forms in the +various species of _Lepidoptera_. They are generally long, slender, and +clubbed at the extremity in butterflies, but exhibit several minor +points of difference which we shall have to note later on. In moths the +antennæ are sometimes long, slender, and pointed. Some are thick, and +more or less prismatic in form; while others are slightly or deeply +pectinated or comb-like. The antennæ of butterflies are always +straight, or only slightly curved; and, although the insects can sway +them bodily, they have no power to bend them, or to stow them away in +any place of shelter. Moths, on the other hand, when at rest, are almost +invariably found to have their antennæ snugly tucked under the wings, +and brought so closely against the side of the head for this purpose +that even the uncovered portion is often difficult to find. + +There are two other prominent appendages belonging to the heads of the +_Lepidoptera_. These are the _labial palpi_ or feelers of the lips. They +are generally easily seen, projecting forward on the under side of the +head, sometimes so long and conspicuous as to give one the idea of a +snout or long nose. The palpi are jointed--usually in three parts--are +covered with scales, and often furnished with hairs or bristles. + +If you watch a moth or butterfly when it is feeding on the sweet juices +of a flower, or on some kind of artificial sweet with which you have +provided it, you will observe its long trunk or _proboscis_, by which +food is sucked up. This instrument is so long and slender that it seems +almost impossible that it can be a tube through which a liquid freely +passes. But a careful examination will show that this is the case. It is +composed of two separate pieces--two half tubes, which, when closely +applied to each other, form a very thin and flexible pipe, perfectly +air-tight and adapted for suction. Sometimes you can see a butterfly or +moth manipulating with its proboscis as if it required readjustment in +some way or other. It has split the tube throughout its length, so that +it now looks like two exceedingly fine hairs. Then, after a short time, +the two halves are put together again, and immediately, as if by magic, +become a single tube in which no kind of seam is to be observed without +a powerful magnifier. + +In order to observe the nature of such a wonderful arrangement we must +have recourse to the aid of a good microscope. Thus assisted, we can see +at once how the junction of the two sides of the proboscis is brought +about so quickly and so perfectly. The inner edges of each half are very +regularly fringed with lines of closely set hairs--so regular, in fact, +are they, that they give one the idea of long yet minute beautifully +formed combs. When the two parts are brought together, the hairs of two +opposite edges interlock, those on one side exactly filling the spaces +between those of the other. + +The microscope also reveals another interesting fact, viz. that the +proboscis is not a single tube, but, although so remarkably thin, is +really a set of three distinct pipes, one lying on each side of the +central one. It is said that the central tube only is used for sucking +up the liquid food, and there seems to be some doubt as to the uses of +the other two. Some naturalists are of opinion that the latter are air +tubes, and are connected with the respiration of the insect; while +others say that through these the insects eject a thin watery fluid with +which to dissolve or dilute those sweetmeats that are not sufficiently +liquid to be readily sucked up. But possibly both these opinions are +correct, the proboscis serving all three of the purposes here named. The +only observation of my own bearing on the subject is this. While a moth +was feeding on a drop of syrup in a strong light, a powerful lens +revealed drops, of liquid, mingled with bubbles of air, passing +alternately _up and down_ the two lateral tubes of the proboscis. At the +same time the upward current of syrup in the central tube was by no +means steady and continuous. + +[Illustration: FIG. 7.--SECTION OF THE PROBOSCIS OF A BUTTERFLY.] + +When this organ is not in use, it is beautifully coiled into a close +spiral which lies between the labial palpi. The length varies +considerably in different insects, and consequently the number of turns +in the spiral must differ also. Sometimes there are less than two turns, +while some of the longer ones form spirals of from six to ten turns. + +In concluding our brief account of the head of lepidopterous insects it +is, I suppose, hardly necessary to add that there is no kind of chewing +apparatus to be described; all the members of this order, at least in +the perfect state, deriving the whole of the little nourishment they +require entirely by suction through the proboscis or 'trunk.' + +The second division of the body is the _thorax_. This is much larger +than the head, and consists of three ring-like segments, joined one +behind the other so intimately that the lines of junction are hardly +visible, even after the thick clothing of fine hair has been brushed +off. Behind the thorax is the abdomen, which is composed of several +segments, the junctions between the rings often being most distinct. + +From the sides of the thorax proceed the two pairs of wings, the general +structure of which we have already to a certain extent examined. But +when we are a little farther advanced in our insect studies, we shall +have to become acquainted with detailed descriptions given as aids to +the identification of species. Now, such descriptions cannot be +satisfactory, either to the one who gives or to him who receives, unless +expressed in such definite terms as render a misunderstanding +impossible. A botanist cannot give an accurate and concise description +of a flower without the use of certain names and expressions which have +gradually become an almost necessary part of his vocabulary; neither can +an entomologist give a really useful, and, at the same time, a +_succinct_ description of an insect unless he is acquainted with the +names of its parts. Therefore, seeing that we distinguish the various +species of butterflies and moths _mainly_ by the arrangement and colour +of the markings of their wings, it is really necessary that we should +know the names of the different parts of these organs. For this reason I +have inserted drawings of a fore and of a hind wing of a butterfly, +together with the names of the various parts of the wings, and also the +names of the principal rays or _nervures_. Yet I would not advise any +young entomologist to attempt to commit to memory all the names given. +Rather use the diagram for reference when occasion requires, more +particularly when you have an insect in your possession that you desire +to study. In ordinary descriptions of butterflies and moths the names of +the _nervures_ are not so generally used as those of the _parts_ of the +wing. Consequently it is exceedingly useful to know what is meant by the +terms _base_, _costal margin_, _apex_, _hind margin_, _anal angle_, +_inner margin_, _discoidal cell_ &c. as applied to the wing. + +The two pairs of wings are attached to the second and third segments of +the thorax; but of the _three_ pairs of legs, which we have next to +consider, one pair arises from each of the three segments. The +arrangement of these limbs is well shown in the sketch on page 3, as are +also the names of the different parts of the limb, the latter being +given for reference by the reader when the need arises. + +All insects, in their perfect state, we are told, have three pairs of +legs; but if you examine the under surface of certain butterflies, such +as the Marbled White, or any of the Vanessas, Browns, or Heaths, it is +quite likely that you will raise objection to such a statement; for in +these you may possibly see only four legs. But this is the result of a +too cursory observation. Look a little more closely at your specimen, +and you will see a pair of smaller legs folded up under the fore part of +the thorax. By means of a blunt needle you can straighten out these +limbs, and then the difference in length to be observed between them and +the other four is very striking indeed. They are also thinner than the +middle and hind legs; and, unlike these, are not provided with claws. + +[Illustration: FIG. 8.--DIAGRAM OF THE WINGS OF A BUTTERFLY. + +I. _Fore wing._--1-5, subcostal nervules; 6, 7, discoidal nervules; +8-10, median nervules; 11, submedian nervure; 12, internal nervure; +13-15, disco-cellular nervules; 16, interno-median nervule; 17, median +nervure; 18, subcostal nervure; _a_, costal nervure; _b_, costa or +anterior margin; _c_, apex or anterior angle; _d_, posterior or hind +margin; _e_, posterior or anal angle; _f_, interior or inner margin; +_g_, base; _h_, discoidal cell. + +II. _Hind wing._--1, 2, subcostal nervules; 3, discoidal nervule; 4-6, +median nervules; 7, submedian nervure; 8, precostal nervure; 9, +subcostal nervure; 10, median nervure; 11, 12, disco-cellular nervules; +_a_, costal nervure; _b_, costa or anterior margin; _c_, apex or +anterior angle; _d_, hind margin; _e_, tail or caudal appendage; _f_, +anal angle; _g_, abdominal or inner margin; _h_, base.] + +These imperfectly developed legs are, of course, quite useless as far as +walking is concerned; indeed, it is extremely doubtful as to whether +they are of any service whatever to the owner. On one occasion, +however, while watching a Peacock Butterfly apparently engaged in +cleaning its divided proboscis, I observed that this organ was +frequently passed under the thorax, and that the front pair of legs were +pressed against it on each side, while it was being drawn outward +between them. It is probable, therefore, that these limbs constitute a +pair of brushes by means of which the fine grooves of the divided trunk +are cleared of any solid or sticky matter that may lodge therein. It is +certain that moths, and those butterflies that possess six _equal_ legs, +use the front pair for this same purpose. The former, also, employ them +for brushing their antennæ, which seem to be, by the way, particularly +sensitive to different kinds of irritation. + +[Illustration: FIG. 9.--THE UNDEVELOPED FORE LEG OF A BUTTERFLY.] + +It is a well-known fact that tobacco smoke has a powerful influence on +certain small insects; and even though it can hardly be regarded as a +perfect all-round insecticide, it is certainly more or less +objectionable to the larger and hardier species. A short time since, +while watching a number of newly emerged moths of the _Sphinx_ group, +and at the same time enjoying the solace afforded by the luxurious weed, +a puff of the smoke was accidentally allowed to play into the box in +which my pets were for the time imprisoned. Immediately they rubbed +their front legs vigorously over the antennæ, as if to remove the +obnoxious irritant that had thus intruded on their presence. Similar +observations have led many naturalists to suppose that the antennæ are +the seat of various senses, such as those of touch, hearing, and smell. +Seeing that insects do not, as far as we know, possess special organs +for all the five senses which we enjoy (and it is interesting to note +here that some insects certainly experience other sensations which are +quite beyond our ken), we can quite understand the common tendency to +locate the seats of certain of the senses in such easily affected parts +as the antennæ. But little, I believe, has been definitely proved save +that the antennæ are sensitive to touch and to irritants generally. + +While speaking of the senses of insects, I cannot refrain from +mentioning a most remarkable example of a peculiar sensitiveness that +has been observed in certain moths of the family _Bombyces_ (page +217)--notably the Oak Eggar, the Emperor, and the Kentish Glory. Take a +newly emerged female of either of these species, shut her up in a small +box, conceal the box in your pocket, and then walk about in some +country spot known to you as being one of the haunts of that species of +moth. Then, if any of the males of the same species happen to be in the +neighbourhood, they will settle or hover about close to the female +which, although still concealed and quite out of their reach, has +attracted them to the spot. + +What a marvellously acute sense this must be, that thus enables the +insects to scent out, as it were, their mates at considerable distances, +even when doubly surrounded by a wooden box and the material of a coat +pocket! You would naturally expect that entomologists have turned this +wonderful power to account. Many a box has been filled with the +beautiful Kentish Glories of the male kind, who had been led into the +snare by the attractions of a virgin Glory that they were never to +behold. Many an Emperor has also been decoyed from his throne to the +place of his execution, beguiled by the imaginary charms of an Empress +on whom he was never to cast one passing glance. And these and other +similar captures have been made in places where, without the employment +of the innocent enchantress, perhaps not a single male could have been +found, even after the most diligent search. + +Speaking of this surprising sense, I am again tempted to revert to the +antennæ; for it is a remarkable fact that the males of those species of +moths which exhibit the power of thus searching out their mates, are +just those that are also remarkable for their very broad and deeply +pectinated antennæ--a fact that has led to the supposition that the +power in question is located in the antennæ, and is also proportional to +the amount of surface displayed by these organs. + +Up to the present time we have been considering the butterfly and moth +in their perfect forms, but everybody knows that the former is not +_always_ a butterfly, nor is the latter always a moth; but that they +both pass through certain preparatory stages before they attain their +final winged state. + +We shall now notice briefly what these earlier stages are, leaving the +detailed descriptions of each for the following chapters. + +The life of the perfect butterfly or moth is of very short duration, +often only a few days, nearly the whole of its existence having been +spent in preparing itself for the brief term to be enjoyed + + ... in fields of light, + And where the flowers of Paradise unfold. + +It may be interesting to consider of what use the metamorphoses of +insects are, and to what extent these metamorphoses render them fit for +the work they have to do. + +It is certain that the chief work of insects, taken as a whole, is to +remove from the earth the excess of animal and vegetable matter. If they +are to do this work effectually, it is clear that they must be very +voracious feeders, and also be capable of multiplying their species +prodigiously. Now each of these powers requires the special development +of a certain set of organs, and an abnormal development of one set must +necessarily be produced at the expense of the other. Hence we find +insects existing in two distinct stages, with or without an intermediate +quiescent state, during the first of which the digestive apparatus is +enormously developed, while the reproductive organs occupy but very +little space; then, during the other stage, the digestive apparatus is +of the simplest possible description, and the organs of reproduction are +in a perfect state of development. + +Allowing, then, that the chief work of the insect is the removal of +surplus organic matter, we can see that a large share of its life should +be spent in the larval or grub stage, and that the perfect state _need_ +not occupy any more time than is necessary for the fertilisation of the +eggs that almost completely fill the body of the female at the time of +her emergence from the chrysalis shell. + +Many insects undergo their metamorphoses by slow degrees, but the +_Lepidoptera_, after existing for some considerable period without any +important visible change in structure, pass by a rapid transition into +the next state. Thus, a caterpillar, that has not altered in general +form for several weeks, changes into a chrysalis within the course of a +few days; and again, after a period of quiescence that may extend +throughout the whole of the colder months, becomes a perfect butterfly +or moth within twenty minutes of the moment of its emergence. + +But this suddenness is more apparent than real, as may easily be proved +by internal examinations of the insect at various stages of growth; +showing that we are led astray by the rapidity of _external_ +changes--the mere _moultings_ or castings of the skin--while the gradual +transformations proceeding within are not so readily observed. + +We have already said that the life of the perfect butterfly or moth is +short. A few days after emergence from the chrysalis case, the female +deposits her eggs on the leaves or stems of the plant that is to sustain +the larvæ. Her work is now accomplished, and the few days more allowed +her are spent in frolicking among the flowers, and sucking the sweet +juices they provide. But males and females alike--bedecked with the most +gorgeous colours and overflowing with sportive mirth when first they +take to the wing--soon show the symptoms of a fast approaching end. +Their colours begin to fade, and the beauty-making scales of the wings +gradually disappear through friction against the petals of hundreds of +flowers visited and the merry dances with scores and scores of playful +companions. At last, one bright afternoon, while the sun is still high +in the heavens, a butterfly, more weary than usual, with heavy and +laborious flight, seeks a place of rest for the approaching night. Here, +on a waving stalk, it is soon lulled to sleep by a gentle breeze. + +Next morning, a few hours before noon, the blazing sun calls it out for +its usual frolics. But its body now seems too heavy to be supported by +the feeble and ragged wings, and, after one or two weak attempts at +play, incited by the approach of a younger and merrier companion, it +settles down in its final resting place. On the following morning a dead +butterfly is seen, still clinging by its claws to a swinging stem, from +which it is eventually thrown during a storm. + +The tale of the perfect moth is very similar to the above, except that +it is generally summoned to activity by the approach of darkness. + +We see, then, that butterflies and moths exhibit none of that quality +which we term parental affection. Their duty ends with the deposition of +the eggs, and the parents are dead before the young larvæ have +penetrated the shell that surrounds them. + +Yet it is wonderful to see how unmistakably the females generally lay +their eggs on the very plants that provide the necessary food for their +progeny, as if they were not only conscious of and careful concerning +the exact requirements of their offspring, but also possessed such a +knowledge of botanical science as enabled them to discriminate between +the plant required and all others. + +Has the perfect insect any selfish motive in this apparently careful +selection of a plant on which to lay its eggs? Does the female herself +derive any benefit from the particular plant chosen for this purpose? In +most cases, certainly not. For it often happens that the blossom of this +plant is not by any means one of those that supply the sweets which +insects love, and still more frequently does it occur that the eggs are +deposited either before the flowers have appeared or after they have +faded. + +Neither can we easily impute to the insect an acquired knowledge of the +nature and wants of her offspring, or an acquaintance with botany +sufficient to enable her to distinguish plant forms. Our only solution +of the problem (which is really no solution at all) is to attribute the +whole thing to that inexplicable quality which we are pleased to term +_natural instinct_. It is to be observed, however, that it is not _all_ +butterflies and moths that display this unerring power. Some few seem to +deposit their eggs indiscriminately on all kinds of herbage. But, I +believe, the larvæ of these species are generally grass feeders, and +would seldom have to travel far from any spot without meeting with an +acceptable morsel. + +[Illustration: FIG. 10.--THE FOUR STAGES OF THE LARGE WHITE BUTTERFLY +(_Pieris Brassicæ_). _a_, larva; _b_, pupa; _c_, imago; _d_, egg.] + +But we must now pass on to a brief consideration of the other stages of +the insect's existence. After a time, varying from a few days to several +months, the young caterpillars or larvæ make their appearance. They soon +commence feeding in right earnest. Their period of existence in this +state varies from a few weeks to several months, and even, in some +cases, to years. During this time their growth is generally very rapid, +and they undergo a series of _moults_ or changes of skin, of which we +shall have more to say in a future chapter. Then, when fully grown, they +prepare for an apparently quiescent form, which we speak of as the +_pupa_ or chrysalis, and in which they again spend a very variable +period, extending over a few days, weeks, or months. Now, inclosed in a +protective case, each pupa is undergoing a remarkable change. Some of +its old organs are disappearing, and others are developing; and, after +all the parts of the future insect have been developed as far as its +narrow shell will permit, it bursts forth into the world as a perfect +insect or _imago_. + +Its wings at first are small, shapeless, and crumpled in a most +unsightly fashion; but it is not long before they assume their full +size, beautiful form, and gorgeous colouring. Then, in about another +hour or two, the wings, at first soft and flaccid, have become +sufficiently dry and stiff to bear their owner rapidly through the air. + +We have thus observed some of the more striking features in the +structure of the butterfly and moth in its most perfect state; and +alluded in a very brief manner to the various stages through which these +creatures must necessarily pass before finally reaching this stage. But +now we must study these earlier stages more closely, and watch the +insects during the marvellous transitions they are destined to undergo. +This we shall do in the following chapters. + + + + +CHAPTER II + +_THE EGG_ + + +I suppose you are all acquainted with the general structure of the hen's +egg, having dissected several, in your own way, many a time. + +Its outer covering, which you speak of as the 'shell,' you have observed +is hard and brittle. It is composed of a _calcareous_ or limy substance, +known chemically as _carbonate of lime_. If you put some pieces of it +into an egg cup, and throw over them a little vinegar or any other +liquid acid, you will see them gradually dissolve away, and small +bubbles of carbonic acid gas will rise into the air. Then again, if you +take a long and narrow strip of the shell, and hold one end of it in a +gas or lamp flame, after a short time that end will become softer, and +will glow brightly in the flame, for it is converted into lime--the same +substance that is used by the builders for making their mortar--and the +bright glow is really a miniature _lime light_, such as is always +produced when a piece of lime is made intensely hot. + +Just inside this shell you have seen a thin membrane or skin that is +easily peeled off the substance of the egg itself. Next to this comes +the 'white' of the egg, which is really colourless while liquid, but +turns white and more or less solid in the cooking. Last of all, in the +centre of this, you have noticed the oval yellow mass that is termed the +'yoke' or 'yolk,' and which contains the embryo of the future chick. + +Now if you imagine this egg to be reduced in size till two or three +dozen of them would be required to form a single line about one inch +long, the outer calcareous shell to be entirely removed, the skin or +membrane to be converted into a firmer substance of a horny nature, and, +finally, the yolk to be absent and the whole internal space to be filled +with the 'white,' you will then have some idea of the nature of the egg +of a butterfly or moth. + +To put the matter more briefly, then, we will say that the eggs of these +insects are simply little liquid masses, usually of a colourless +substance, surrounded by a horny and flexible covering. + +Such a description may certainly give you some idea of the nature of the +eggs of insects, but no amount of book reading will serve the purpose so +well or be so pleasant as the examination of the eggs themselves. During +the summer months very little difficulty will be experienced in finding +some eggs in your own garden. Turn over some leaves and examine their +under surfaces, choosing especially those plants which show, by their +partially eaten leaves, that they are favourites with the insect world. +Or you may amuse yourself by catching a number of butterflies--common +'Whites' are as good for the purpose as any--and temporarily confine +them in a wooden or cardboard box, containing a number of leaves from +various plants, and covered with gauze. In this way you are sure to +obtain a few females that have not yet laid all their eggs; and if you +watch your prisoners you will soon see them carefully depositing the +eggs on the under surfaces of leaves, bending their abdomens round the +edges if there is not sufficient room to get themselves completely +under. And then, when you are satisfied with the number of eggs thus +obtained for your examination, you can have the pleasure of seeing all +your liberated captives flying joyfully in the free air. + +In giving these simple instructions I have assumed that the reader has +not yet learnt any of the characters by which female butterflies are to +be distinguished from their lords and masters; but I hope that he will +know soon, at least with regard to a good many species, from which +individuals he may most reasonably expect to obtain eggs, and so be able +to avoid the imprisonment, even though only temporary, of insects which +cannot satisfy his wants. + +Again, it is not necessary, after all, that butterflies should be +captured for the purpose of obtaining eggs. Watch them as they hover +about among your flowers. Some, you will observe, are intent on nothing +but idle frolicking; and you may conclude at once that _these_ have no +immediate duty to perform. Others are flying without hesitation from +flower to flower, gorging themselves with the sweets of life: these are +not the objects of your search. But you will descry certain others, +flying round about the beds and borders with a steadier and more +matronly air, taking little or no notice of their more frivolous +companions, and paying not the slightest heed to the bright +nectar-producing cups of the numerous flowers. These are seriously +engaged with family affairs only. Watch one of them carefully, and as +soon as she has settled herself on a leaf, walk steadily towards her +till you are near enough to observe her movements. She will not move +unless you approach too closely, for, like busy folk generally, she has +no time to worry about petty annoyances. You will now actually witness +the deposition of the eggs exactly as carried on in the perfect freedom +of nature; and the eggs themselves may be taken either for examination +or for the rearing of the caterpillars. + +Some species of _Lepidoptera_ lay some hundreds of eggs, and it is +seldom that the number laid by one female is much below a hundred. + +As already stated, the under surfaces of leaves are generally chosen for +the deposit of eggs, but a few of the insects we are considering always +select the upper surface for this purpose. Thus the Puss Moth (page +235), and two or three others resembling it, though much smaller, known +as the Kittens (page 234), invariably lay them on the upper surface. And +this is the more surprising since the eggs of these moths are brown or +black, and consequently so conspicuous on the green leaves as to be in +danger of being sighted by the numerous enemies of insects. + +The Hairstreak Butterflies (page 183) afford another exception to the +general rule, for their eggs are deposited on the _bark_ of the trees +and shrubs (birch, sloe, elm, oak, and bramble) on which their larvæ +feed. + +At the moment each egg is laid it is covered with a liquid sticky +substance, so that it is immediately glued to the leaf or stem as soon +as it is deposited. The sticky substance soon dries, causing the egg to +be so firmly fastened in its place that it is often impossible to force +it off without destroying it completely. + +Some of the _Lepidoptera_ deposit their eggs singly, or in small +irregular clusters; but by far the larger number set them very regularly +side by side, in so compact a mass that it would be impossible to place +them on a smaller area without piling one on top of another. This is not +accomplished with the aid of the sight, for the insect performing her +task with such precision often has her head on one side of a leaf or +stem while arranging her eggs on the other. If you take the trouble to +watch her, you will see that she carefully _feels_ out a place for each +egg by means of the tip of her abdomen immediately before laying it. + +The eggs are laid by moths and butterflies at various seasons of the +year. In some cases they are deposited early in the spring, even before +the buds of the food plants have burst; and the young larvæ, hatched a +few weeks later, commence to feed on the young and tender leaves. Then, +throughout the late spring, the whole of the summer and autumn, and even +till the winter frosts set in, the eggs of various species are being +laid. + +Those deposited during the warm weather are often hatched in a few days, +but those laid toward the autumn remain unchanged until the following +spring. + +In this latter case the frosts of the most severe winter are not capable +of destroying the vitality of the eggs. In many instances the perfect +insect or the larva would be killed by the temperature of an average +winter day, but the vitality of the eggs is such that they have been +subjected to a temperature, artificially produced, of fifty degrees +below the freezing point, and even after this the young larvæ walked out +of their cradles at their appointed time just as if nothing unusual had +occurred. + +Experiments have also been performed on the eggs with a view of +determining how far their vitality is influenced by high temperatures. +We know that the scorching midsummer sun has no destructive influence on +them, but these experiments prove that they are not influenced by a +temperature only twenty degrees below the boiling point--actually a +considerably higher temperature than is _necessary_ to properly cook a +hen's egg. + +Let us now examine a number of eggs of different species, that we may +note some of the many variations in form and colour. + +With regard to colour, we have already observed that the eggs of a few +species are black; but more commonly they are much lighter--pearly +white, green, yellow, and grey being of frequent occurrence. + +The great variety of form, however, will provide a vast amount of +enjoyment to anyone who possesses a good magnifying lens or a small +compound microscope. Some are globular, others oval; while many others +represent cups, basins, and domes. Then we have miniature vases, flasks, +bottles with short necks, and numerous figures that must remind a +juvenile admirer of the sweet cakes and ornamental jellies that have so +often gladdened his longing eyes. + +Again, the beautifully sculptured surfaces of a large number are even +more striking than their general shapes. Some are regularly ribbed from +top to bottom with parallel or radiating ridges, and at the same time +marked with delicate transverse lines. Others are beautifully pitted or +honeycombed, some ornamented with the most faithful representation of +fine wicker-work, while a few are provided with a cap, more or less +ornamental, that is raised by the young larva when about to see the +world for the first time. A few of these beautiful forms are here +illustrated and named, and another has already appeared on page 14, but +an enthusiastic young naturalist may easily secure a variety of others +for his own examination. + +[Illustration: FIG. 11.--EGG OF THE MEADOW BROWN BUTTERFLY.] + +[Illustration: FIG. 12.--EGG OF THE SPECKLED WOOD BUTTERFLY.] + +[Illustration: FIG. 13.--EGG OF THE VAPOURER MOTH.] + +It may be surmised from the accompanying illustrations that the form of +the egg is always the same for any one species. This is really the case, +and consequently an experienced entomologist can often decide on the +name of the butterfly or moth that deposited a cluster of eggs he +happens to find in his rambles and searchings; but in such decisions he +is always greatly assisted by a knowledge of the food plants of the +various insects, and sometimes also by the manner in which the eggs are +arranged. + +We have seen that the period during which the _Lepidoptera_ remain in +the egg stage is very variable, and depends largely on the season in +which they were laid; but it is often possible to tell when to expect +the young larvæ by certain changes which take place in the appearance of +the egg. As the horny covering of the egg is transparent, the gradual +development of the caterpillar from the clear fluid can be watched to a +certain extent; but if you have a microscope, and would like to witness +this development to perfection, proceed as follows. + +Arrange that some butterflies and moths shall lay their eggs on strips +of glass of convenient dimensions for microscopic work--three inches +long by one wide is the usual size for this kind of work. This is easily +accomplished by placing a proper selection of female insects in a rather +small box temporarily lined with such 'slips.' When a few eggs have thus +been secured, all you have to do is to examine them at intervals with +your microscope, always using the reflector so as to direct a strong +light _through_ the eggs from below. + +But even without such an arrangement some interesting changes are to be +observed. As a rule, the colour of the egg turns darker as the time for +the arrival of the infant larva approaches, and you will often be able +to see a little brown or black head moving slightly within the 'shell.' +You may know then that the hatching is close at hand, and the movements +of the tiny creature are well worth careful watching. Soon a small hole +appears in the side of the case, and a little green or dark cap begins +to show itself. Then, with a magnifier of some kind, you may see a pair +of tiny jaws, working horizontally, and not with an up-and-down motion +like our own, gradually gnawing away at the cradle, till at last the +little creature is perfectly free to ramble in search of food. + +Strange to say, the young larva does not waste a particle of the horny +substance that must necessarily be removed in securing its liberty, but +devours it with an apparent relish. Indeed, it appreciates the flavour +of this viand so highly that it often disposes of the whole of its +little home, with the exception of the small circular patch by which it +was cemented to the plant. When the whole brood have thus dispensed with +their empty cradles, there remains on the stem or leaf a glittering +patch of little pearly plates. + +After the performance of this feat the young caterpillar starts off in +life on its own account with as much briskness and confidence as if it +had previously spent a term in the world under the same conditions; but +we must reserve an account of its doings and sufferings for our next +chapter. + + + + +CHAPTER III + +_THE LARVA_ + + +In almost every case the young caterpillar, on quitting the 'shell' of +the egg, finds itself standing on and surrounded by its natural food, +and immediately commences to do justice to the abundant supply. It will +either nibble away at the surface of the leaf, removing the soft +cellular substance, so that the leaf exhibits a number of +semi-transparent patches when held up to the light, or it will make +straight for the edge, and, closing its horizontal jaws on either side, +bite the leaf completely through, and thus remove a small piece each +time. + +[Illustration: FIG. 14.--THE CATERPILLAR OF THE CLOUDED YELLOW +BUTTERFLY.] + +Several naturalists have amused themselves by performing experiments and +making calculations on the efficiency of the masticating and digesting +powers of the caterpillar. The illustrious Réaumur, for example, proved +that some of the cabbage eaters disposed of more than twice their own +weight of food in twenty-four hours, during which time their weight +increased one-tenth. Let us see what this would be equivalent to in +human beings: A man weighing eleven stone would devour over three +hundred pounds of food in a day, and at the end of that day weigh about +fifteen pounds more than he did at the beginning! + +So the young caterpillar eats, and rests, and grows, till, while still +young, its body has become too large for the already tightened skin. It +evidently feels very uncomfortable. Its appetite fails, and it remains +for a time perfectly quiet in one spot, having previously spun a little +carpet of silk to form a firm foothold during its temporary +indisposition. Its colours have also become dingy, and anyone, not +understanding the character of its growth, might easily be led to +suppose that the poor creature was displaying the earlier symptoms of a +serious and perhaps fatal illness. + +But soon an encouraging symptom is observed. The caterpillar begins to +get restless. Its front segments are turned alternately right and left, +and are also made to swell out much beyond their normal size. Then in a +very short time--often less than a minute from the first appearances of +restlessness--the skin, which has become somewhat dry and brittle, +splits along the back over the second, third and fourth segments, +revealing a new and bright coat beneath. The caterpillar continues its +struggles and, in addition to the previous movements, causes the +swelling to move backward along the body. This, acting like a wedge, +causes the rent in the old coat to extend in that direction. + +[Illustration: FIG. 15.--THE CATERPILLAR OF THE DARK GREEN FRITILLARY +BUTTERFLY.] + +The caterpillar now draws its head backward, and, with a few convulsive +struggles, pulls the front segments out of their old skin, and passes +its head out of the rent in the back. With its foremost segments thus +rendered perfectly free, it walks straight out of the old garment, which +is left still fixed by the legs to the silken carpet. + +The larva, although now fresh and smart in its appearance, is exhausted +by these struggles and its prolonged fast. The new skin, moreover, is +very soft and tender, even to the cases of the head and legs, which are +normally very hard. But a short period of rest suffices to dry its skin +and sharpen its appetite, and then it eats more vigorously than ever. + +We will now leave the caterpillar for a moment while we look at its +cast-off clothes. They are still clinging to a stem so firmly that they +can scarcely be removed without injury. The hard shell that covered the +head and jaws is perfect in form, and so are the claws and cases of the +legs. All the hairs or spines that happened to adorn the previous owner +still retain their positions; and the whole skin, although always more +or less shrivelled, is sometimes so slightly altered in form that it +might be mistaken for a living caterpillar if not closely examined. + +But this is not all. For, according to the accounts of some +authoritative observers, the lining of the digestive organs, which is +really a continuation of the outer skin, is cast off (or rather cast +_out_) at the same time, as are also the linings of the larger breathing +tubes which are presently to be described. + +We have seen that some caterpillars, on quitting their egg cases (which +may really be regarded as the first moult), make their first meal of the +old covering. So also some of them, in their future moultings, exhibit +an apparently useless economy (seeing that they are surrounded by an +abundance of their natural vegetable diet) by devouring their old coats! +In the face of this fact we can hardly describe them as strict +vegetarians. + +[Illustration: FIG. 16.--THE CATERPILLAR OF THE PURPLE EMPEROR +BUTTERFLY.] + +Having thus passed through its first hardship, the caterpillar has by no +means seen the end of the troubles and dangers that beset it; for, +during its existence in the larval state, it has to go through a series +of three, four, five, or even six moults, all of which are periods of +considerable inconvenience, and perhaps even pain, and frequently prove +fatal. And it is by no means an uncommon thing to meet with the lifeless +body of an unfortunate individual who, as shown by its shabby appearance +and the silken carpet under its feet, has evidently fallen a victim to +the dangerous process of ridding itself of an old garment. + +But this is only one of the many dangers to which caterpillars are +exposed. Throughout every hour of the day the sharp and hungry eyes of +the numerous insect-eating birds are searching the leaves for such +delicacies to satisfy the wants of themselves and their broods. The +lively little lizards, too, during the sunny hours are busily engaged in +searching them out among the foliage of heaths and banks. + +Very formidable enemies also exist in the form of Ichneumon and other +species of flies, which pierce the skins of caterpillars with their +sharp _ovipositors_, and lay their eggs within the bodies of the +unfortunate victims. As soon as the young larvæ are hatched from these +eggs, they commence feeding on the fatty substance stored beneath the +caterpillar's skin. They carefully avoid, at first, attacking the vital +organs of their host's body, and in this way secure for themselves a +more lasting supply of fresh food. When the fatty substance is nearly +all gone, they eat their way into the more important structures, of +course steadily growing all the time; and so, even though the body of +the caterpillar is rapidly diminishing, the total bulk shows often no +very appreciable decrease in size. When the larvæ of the flies are fully +fed, they either change to the pupa within the carcase of their host, or +eat their way out of its body and construct for themselves a cocoon in +which to undergo the transformation. + +As for the caterpillar itself, it sometimes dies before the time for its +metamorphosis has arrived; but it often changes to the chrysalis before +its fate is sealed. In this latter case, a number of flies, having +undergone their final transformation within the chrysalis shell (there +being but little else than shell remaining of the victim's body), break +forth from the remains of the carcase somewhere about the time at which +the butterfly or moth should have appeared. + +[Illustration: FIG. 17.--AN ICHNEUMON FLY (_Cryptus Migrator_).] + +[Illustration: FIG. 18.--ANOTHER ICHNEUMON FLY (_Pimpla Instigator_).] + +Caterpillars have also their nocturnal enemies and devourers, among +which may be mentioned frogs, toads, newts, and insect-eating mammals. + +We must now learn something of the structure of caterpillars; and then +become acquainted with their habits, and the change to the chrysalis or +pupa. + +Take a caterpillar from your garden, preferably a full-grown one of a +rather large species, that is not very densely covered with hair, and +examine it carefully as we note the main points in its structure. The +first point that strikes our notice is the division of its body into +segments or rings, separated from each other by a more or less distinct +line or slight constriction of the body. + +There are thirteen of these segments, reckoning, as is usual, the head +as the first. + +The head is usually very hard, and often of a much darker colour than +the rest of the body. It is also frequently divided into two lobes by a +couple of oblique lines, between which the parts of the mouth are +situated. The two powerful horizontal jaws, to which we have already +referred, are very hard and sharp, and curved like a sickle, and +therefore splendidly adapted for biting from the edges of leaves. The +head is also provided with a pair of antennæ, usually very short and +inconspicuous and protected by a horny covering. + +Unlike the perfect insect, the caterpillar has no large compound eyes, +but twelve very small simple eyes, situated on the cheeks, very near the +mouth--six on each side. + +[Illustration: FIG. 19.--THE CATERPILLAR OF THE ANGLE SHADES MOTH +(_Meticulosa_).] + +If you examine them with a magnifier, you see that each one is provided +with a small and very convex lens--a lens of very _short focus_, such as +would be used for the examination of small objects held very near to the +eye. From this arrangement we should be inclined to conclude that the +caterpillar can see only those objects that are close to its mouth; and +this idea is strengthened if you place one in a box containing a number +of leaves, one of which is that of its own food plant. It will wander +about the box, apparently looking at every part of every leaf it passes, +after the manner of a very short-sighted individual, and never taking a +general look round. A butterfly or a moth can see a flower in the +distance, for it flies unhesitatingly from one to another in the +straightest and shortest path, but if you place a caterpillar in the +centre of a ring composed of a leaf of its food plant and nine others +from other plants, the chances are (nine to one) that it will _not_ walk +towards what it would like to have. + +Again, the eyes are situated on the _lower_ part of the cheek, directed +slightly downward, and are therefore adapted for seeing what is just +under its jaws as it walks along. Had we no knowledge whatever of the +caterpillar's twelve little eyes, we should probably have thought that +it sought out its food by some sense other than that of vision. + +Another important and interesting feature of the head is the +silk-spinning apparatus, situated under cover of the lower lip. This +consists of two tubular glands, corresponding to our own salivary +glands, the special purpose of which is to secrete a viscid fluid that +solidifies on exposure to air. The opening by which the fluid escapes is +so situated that the caterpillar can easily apply it to the surface of +any object over which it is walking, and then, by drawing or turning +away its head, cause a silken fibre to be produced. + +Some caterpillars make use of this spinning apparatus only on a few +special occasions, but others, more especially some of the smaller +species, seem to have it always in use, so that if at any time you +suddenly start them into the air by giving a smart tap to the plant or +twig on which they rest, they invariably fall slowly on the end of a +growing web, the spinning of which they stop as soon as they consider +they have fallen far enough. Sometimes, as you are walking through a +wood, you will see hundreds, nay, thousands of little caterpillars thus +suspended, swinging gently in the breeze. Not long since, after only a +few minutes' walk among the trees of Epping Forest, I found I was +decorated with several dozens of these swingers with which I had come +into collision--in this case consisting chiefly of the larvæ of the +Green Tortrix Moth (_Tortrix viridana_). + +Now let us examine the caterpillar's limbs. Attached to each of the +second, third, and fourth segments is a pair of true walking legs, +corresponding with those of the perfect insect. These are covered with a +hard and shining substance, and are also each provided with a hook. The +fifth and sixth segments have no limbs at all, nor have the eleventh and +twelfth, but some or all of the others (seventh, eighth, ninth, tenth, +and thirteenth) are furnished with a pair of claspers which we shall +presently describe. + +First, as regards the number of claspers, it will be seen from what has +just been said that this is not always the same. Some caterpillars +possess five pairs, thus making up the total number of walking +appendages to sixteen. In fact, we must regard this as the _usual_ +number. But there are at least a few hundred exceptions to the rule. +Many of the _Bombyces_ (page 217), for example, have only four pairs of +claspers; and in others of the same group the fifth pair is present, but +only partially developed, and quite useless for walking. + +Look at the peculiar caterpillar of the Lobster Moth (fig. 23)--a +creature that differs from most other caterpillars not only in its +claspers, but in many other respects too. Observe its long and slender +legs, its humped middle segments, and its upturned hindermost segment, +of enormous size and mounted with a pair of clubbed 'horns.' This last +segment you will observe, has no claspers. + +[Illustration: FIG. 20.--WALKING LEG OF A CATERPILLAR.] + +[Illustration: FIG. 21--LARVA OF THE YELLOW UNDERWING MOTH (_Pronuba_).] + +[Illustration: FIG. 22.--LARVA OF THE CRIMSON SPECKLED MOTH +(_Pulchella_).] + +[Illustration: Fig. 23.--LARVA OF THE LOBSTER MOTH (_Fagi_).] + +Another allied caterpillar is that of the Iron Prominent Moth (fig. 24). +This one also has humped segments, and the claspers of the thirteenth +segment are imperfectly developed. + +A large number of other exceptions to the general rule are to be found +in the caterpillars of the Geometer Moths (page 268), one of which is +here represented. These have generally only two pairs of claspers, one +pair on each of the tenth and last segments, so that there is a distance +equal to the combined length of six segments between the hindermost true +leg and the first pair of claspers. But even among the Geometers there +are variations to be observed in the number of claspers, and some of +these will be pointed out in our brief descriptions of the commoner +species. + +[Illustration: FIG. 24.--CATERPILLAR OF THE IRON PROMINENT MOTH +(_Dromedarius_).] + +[Illustration: FIG. 25.--LARVA OF THE BRIMSTONE MOTH (_Luteolata_).] + +These limbs which we have been calling claspers are known by several +other names. Thus they are termed 'pro-legs,' 'temporary legs,' 'false +legs,' and 'abdominal legs;' but if you watch a caterpillar as it walks +up a stalk or along the edge of a leaf, you will certainly agree that +the term 'clasper' is everything that could be desired. But why not call +them legs, seeing that they are used in walking? The reason is that they +differ in many respects from the three foremost pairs of limbs as +regards structure, persistency, and function. The true legs, as we have +called them, continue to exist, though concealed, in the chrysalis +state, and again appear, far more perfectly developed, in the butterfly +or moth, but the claspers are no more to be seen after the caterpillar +has passed into the quiescent stage. We have noticed, too, that the true +legs are pointed and clawed, also that they are protected by a hard and +horny covering; but examine a large caterpillar, holding it between the +fingers and thumb with its under side uppermost, and you will soon see +that the claspers are not at all hard, but soft and fleshy; not pointed, +but often terminating in a broad flat circular surface. You will also +observe, as the creature struggles to escape from your grasp, and tries +to get a hold on something with its claspers, that these limbs, if we +may so call them, are retractile, and are sometimes completely drawn +into the body. Finally, examine the broad end of a clasper with a +magnifier, and you will see it surrounded by a circle of little hooks, +turning in all directions. You will no longer wonder how it is that a +caterpillar can hold so tenaciously to a piece of twig that it is often +almost impossible to remove it without injury. + +Now put your caterpillar down, so that you may observe its gait. If it +happens to be one with the full complement of sixteen limbs, you see +that at each stride it makes but little progress. The segments contract +and relax alternately and in succession, thus sending a series of +wave-like motions along the body, and urging onward the front segments +while the claspers keep the hinder portion firmly fixed. + +[Illustration: FIG. 26.--THE CLASPERS OF A CATERPILLAR.] + +But if your caterpillar is one of the Geometers, with only two, or +perhaps three, pairs of claspers, the mode of procedure is very +different. The creature stretches its body out at full length, often +raising its head high in the air, and swinging its long body right and +left with a most furious motion, as if to hastily scan the +neighbourhood. Then, having satisfied itself as to the _direction_ of +its proposed course (which, by the way, is often changed considerably at +almost every stride), it holds on by the true legs and pulls its hinder +quarters forward till the body forms almost a closed loop, with the +fourth segment nearly touching the ninth. The claspers now become the +holdfasts. The little hooks with which they are provided are firmly +fixed to the surface on which it is walking; and the body being again +straightened out to its utmost length, the same man[oe]uvre is repeated. +So, you see, the insect progresses by strides equal in length to about +six segments of the body, and these the longest segments generally; and +the rate at which the strides succeed each other, especially in some of +the smaller species, is really astonishing. + +We have seen the caterpillar in the act of taking its walk, and now we +will give it a twig of its food plant so that we may see it feed. It +walks up the twig without hesitation--for caterpillars (excepting those +which feed on roots) always seem to move upward when in search of +food--and soon finds itself on a leaf. Over this it walks till it +reaches the edge; and, grasping the edge firmly between the claspers, so +as to give perfectly free play to its legs and head, it stretches its +body at full length, and takes a series of bites as it brings its head +backward in a curve. When the head has thus been brought close to its +fore legs, the body is again extended, and the same ground is gone over +again. + +If the caterpillar is a fairly large and hardy one, it will bite through +the smaller veins, and perhaps even the larger ones; but the smaller +species often change their position on reaching a moderately thick vein, +and so devour little else than the soft cellular substance of the leaf. +In any case, it is astonishing to see how rapidly the leaf disappears +under the influence of the powerful jaws and marvellous digestive +apparatus of the hungry grub. + +Those who take a delight in watching the _movements_ of caterpillars are +sure to be interested in observing them when at rest; for at such times +the various attitudes assumed are as pleasing and instructive as are +their active moments. And these attitudes are all the more interesting +on account of the mimicry by which the creatures often baffle their +numerous enemies. We may profitably spend a little time in studying a +few cases in point. + +Many species, when at rest, fix themselves by means of their claspers to +a small twig or leaf stalk, or on the midrib of the leaf itself. Here +they remain perfectly still, with their bodies perfectly straight or +with head slightly raised. I need hardly say that these generally fix +themselves on the _under_ side of the leaves and stalks, thus securing +themselves against the attacks of the feathered foes above. But some +birds are equal to the caterpillars in this matter; and it is really +amusing to see them hopping about beneath the leaves in our gardens, +every now and again slyly turning one eye upward, and smartly plucking +an unwary grub from its resting place. + +The precautions of the caterpillar, however, do not end merely with the +selection of an under surface. You will find that the bright green +species invariably settle on a leaf or a _green_ stalk, while the darkly +coloured insects often choose a twig covered with a brownish bark. Some +even make for the _trunk_ of the tree on which they feed, and here +remain quite still in a vertical position, so that they look just like a +ridge in the bark, the colour of which is faithfully imitated by their +skin. Further, many of the caterpillars that resort to this stratagem +have bodies that are notched or knotted and spotted in such a manner +that the resemblance to their surroundings is so perfect as to defy any +but the most experienced eye. And even this is not all, for a number of +these mimics of the insect world never venture to feed by day, but take +in their quantum of provisions during the dark hours, and practise their +deceptions throughout the day. + +Most of the Geometer caterpillars, of which we have already spoken, are +well trained in the art of deception. You are out on a caterpillar hunt, +and engaged in carefully turning over the twigs of the hazel or some +other shrub, so that you may the more readily examine the under surfaces +of the leaves. At last you lay hold of a small broken twig for this very +purpose. To your astonishment it is very soft, and readily bends between +your fingers. You look more closely at this peculiar piece of stick, and +find, to your surprise, that you have grasped a looper caterpillar that +was standing out at an angle just like a broken twig, supported by its +two pairs of claspers, and coloured and knotted exactly like the little +branch on which it rested. + +At other times you meet with little green caterpillars of the same +group, supporting themselves in exactly the same manner on a small twig, +and looking just like a leaf stalk from which the blade had fallen or +been devoured. + +What a wonderful power is exhibited in the grasp of the claspers and the +tension of the muscles, enabling the caterpillar to fix itself and +retain its position for so long a time! Imagine an acrobat fixing +himself by his hands on an upright pole, throwing out his body at an +angle, and without any further support retaining his position motionless +for several hours! + +Other experiences of the larva hunter are equally interesting and, +perhaps, even more tantalising. He is engaged in very cautiously turning +over the leaves of a certain food plant from which he hopes to obtain +the larva of a much-coveted species. Then, just as his eye catches a +glimpse of the very object of his search, down falls the caterpillar, +rolled up into a little ball, among the herbage below. This latter is +diligently and patiently examined. But no, the anticipated prize is +nowhere to be seen. It is probably a green one, and this adds to the +difficulty of the patient entomologist. Then, as he carefully separates +the low herbs, hoping to find the spot where the larva had fallen, the +insect, rolled up into a compact little ball, only sinks deeper and +deeper into the maze. + +Many caterpillars avoid capture in this manner, while others seek to +avoid detection by remaining perfectly motionless, even when roughly +handled. They allow themselves to drop from their resting place on the +slightest sign of danger, and, when the alarm is over and all is quiet +again, they ascend the food plant and resume their position. + +Some caterpillars not only rest, but even feed under cover, quite secure +from most, if not all, of their enemies. Several of them feed on roots, +and many a farmer can relate sad experiences of the havoc committed by +these caterpillars on his turnips and other crops. Then there are those +which feed on flowers and buds, completely burying themselves in the +dense mass of food. + +[Illustration: FIG. 27.--THE HOMES OF LEAF MINERS AND LEAF ROLLERS.] + +We must conclude this brief account of resting and hiding places and +attitudes of caterpillars by a few observations on the leaf miners and +leaf rollers. + +The former are very small caterpillars--the larvæ of certain small +moths--that eat burrows into leaves without doing any considerable +injury to the outer _epidermis_, and thus prepare a safe resting place +within the substance of their food. + +The latter, also mostly of small size, make themselves secure by curling +a leaf or a portion of a leaf into a cylinder, and holding it in +position by means of a number of silken threads. + +If you examine a leaf thus curled you will soon be convinced that a +considerable number of the extremely delicate threads must be necessary +to hold it in position; but, if you would like to know how a very small +and feeble caterpillar can manage to roll up a comparatively large and +rigid leaf, you must watch the little creature at its work. + +You need have but little difficulty in finding a willing worker, for +such caterpillars are extremely numerous. Take a few out of their +self-made homes, place them on a sprig of the food plant, and you will +soon have the pleasure of seeing one start its extraordinary work. + +At first it spins a number of threads stretching from the edge of a leaf +to about the middle of the surface. These threads are not tight by any +means, and the leaf is, as yet, unchanged in position. But now the +little mechanic exhibits a tact that almost seems to prove a knowledge +of the principles of its art. Each thread in turn is pulled _at right +angles_ at its middle, and then fastened by means of the creature's +spinneret. Each time this is done the edge of the leaf is bent round _a +little_; and when at last the cylinder is completed, a number of other +threads are stretched across from the scroll to the flat part of the +leaf to secure it firmly in its place. + +Many caterpillars are solitary in their habits: that is, they are always +found singly, whether walking, resting, or feeding. But a large number +of species are gregarious, living in dense clusters either throughout +their larval state or, perhaps, only while young. In many such cases it +is difficult or even impossible to find any reason for this gregarious +tendency--to discover any advantage that the insects may derive from the +habit. Many species, however, are true co-operators in the defence of +their communities. The caterpillars of such live in clusters, sometimes +several scores in each, and all help in the spinning of a complicated +mass of silk fibres, which, with the leaves and twigs they join +together, form a safe home in which they can rest, feed, or change to +the chrysalis state. In early summer hundreds of such caterpillar +'nests' are to be seen in many of our hawthorn and other hedgerows. + +Before closing our general account of the caterpillar we must have a +word to say about the breathing apparatus, more especially as in our +future descriptions we shall frequently have to mention the colours and +markings which surround the openings in its body through which the air +supply is admitted. + +If you examine the sides of the segments of a caterpillar, using a lens +if the insect is a small one, you will observe some little round holes, +often inclosed in a ring or a patch of some prominent colour. These are +the _spiracles_ or openings of a series of air tubes called _tracheæ_. +These latter divide and subdivide within the body of the caterpillar, +the branches of one often uniting with those of another, thus forming a +really complicated arrangement of air pipes by which the supply of +oxygen is distributed. + +A microscopic examination of a portion of one of the tracheæ will show +that its walls are supported by an elastic spiral of a firm substance. +This arrangement serves to keep the air passages open, and secures for +the caterpillar a free supply of air at times when a contraction of the +segments would otherwise cause the tubes to collapse. + +There are nine spiracles on each side of the caterpillar's body, and +never more than one in the side of the same segment. The head, which we +have been regarding as the first segment, has no spiracles. The second +segment has a pair--one on each side. There are none in the third and +fourth; but all the segments, from the fifth to the twelfth inclusive, +have each a pair; the last (thirteenth) segment has none. + +We have already observed the general arrangement of the caterpillar's +limbs; but perhaps it may be interesting and even convenient to the +reader to give here a little table that will show at a glance the +disposition of both limbs and spiracles. + + First segment--head Two short antennæ, two jaws, + and twelve eyes. + Second " Legs and spiracles. + Third " Legs only. + Fourth " Legs only. + Fifth " Spiracles only. + Sixth " Spiracles only. + Seventh " Spiracles, and sometimes + claspers. + Eighth " Spiracles, and sometimes + claspers. + Ninth " Spiracles, and sometimes + claspers. + Tenth " Spiracles, and generally + claspers. + Eleventh " Spiracles only. + Twelfth " Spiracles only. + Thirteenth " Claspers only, and these + occasionally absent. + +We must now watch the caterpillar through its later days, to see how it +prepares for passing into the pupal stage, and to witness the various +interesting changes that take place at this period. + +When fully grown, it ceases to eat, and begins to wander about in search +of a convenient spot for the coming event. Its colours fade, and the +body becomes appreciably smaller, especially in length, as it ejects the +whole contents of its digestive apparatus. According to some accounts, +it even evacuates the lining of the intestines with their contents. + +A great variety of situations are chosen by the different species at +this time. Some will fix themselves on their own food plant, and there +remain till they finally emerge in the perfect state, suspending +themselves from a silken carpet, hiding themselves in a rolled leaf, or +constructing a cocoon of some kind. A large number walk down the food +plants, and undergo their changes in moss that happens to lie at the +foot; or construct a cocoon on the surface of the ground, utilising for +the purpose any decayed leaves, fragments of vegetable matter, or pieces +of earth or small stones. Many seek a further protection than this, and +burrow into the soil, where they either lie in a little oval cell that +they prepare, or in a cocoon constructed by spinning together some +particles of earth. Again, there are those caterpillars, chiefly of +butterflies that frequent our gardens, which find their way to the +nearest wall or fence, and there secure themselves in a sheltered nook. +We will watch a few of these varied methods of procedure, taking as our +first instance the caterpillar of the common Large White or Cabbage +Butterfly. + +When fully fed, this larva seeks out a sheltered spot, generally +selecting the under surface of some object, or of the ledge of a wall or +fence. Sometimes it will not even leave its food plant, though it +generally walks some considerable distance before a suitable shelter is +found. Having satisfied itself as to the site of the temporary abode, it +sets to work at spinning a silken carpet. At first the threads spread +over a rather wide area, and seem to be laid in a somewhat irregular and +aimless manner; but after a little time its labours are concentrated on +one small spot, where it spins several layers of silk fibres. + +This done, it fixes the little hooks of the claspers firmly in its +carpet bed, and then proceeds with a highly interesting movement. It is +not satisfied with only the one mode of suspension. In fact, this alone +would hardly be safe, for when it casts its skin, as it is shortly about +to do, its claspers will all disappear; and although it afterwards +secures itself by the 'tail,' it would be dangling in such a manner as +to swing with every breeze--a very unsatisfactory state of affairs, +especially with those that pupate late in the summer and remain in the +pupal state throughout the winter storms. + +Its next procedure, then, is to make a strong silk band round the middle +of its body, so as to keep it close to the surface against which it +rests. But how is this to be done? It bends its head round till the +spinning organ can be applied to a point close beside the middle of its +body. Here it fixes one end of a thread; and then, gradually twisting +its body, brings its head round to the other side, still keeping it +close to the same segment, and fastens the other end of the thread +exactly opposite the point at which it started. + +The head is now brought back to its former position, thus adding another +thread to the band; and the process is repeated several times, till at +last the caterpillar is satisfied with the thickness and strength of the +cord formed. + +Now it straightens out its body as if to rest from its labours; but the +work is not yet complete. Soon it exhibits much restlessness. Its +foremost segments are seen to shorten, and consequently become thicker. +Then the skin splits, and the last moult of the caterpillar commences. +The movements that follow are exactly similar to those we have already +described in connection with one of the earlier moults: the alternate +and successive contractions of all the segments gradually force back the +old coat, and this is finally thrown entirely off by a somewhat vigorous +wriggling of the 'tail.' + +Then, for a moment, the creature is supported only by its silken cord. +But this lasts _only_ for a moment. For, as soon as it is quite free +from the old garment, it applies its tail to the densest part of the +carpet it had prepared at the start, and secures its hinder extremity by +means of little hooks. + +But what a change has now come over the creature! It is no longer a +caterpillar. Its head is no longer distinct, although we can readily +make out the positions of the eyes. Its mouth and jaws have quite +disappeared, and the legs and claspers are apparently gone. The three +segments that bore the legs are no longer distinctly separable, though +in reality they still exist. The head and thorax are peculiarly shaped; +and, instead of being cylindrical, are angled and ridged; but, beneath +the soft greenish skin--the new garment--we can discern the outline of +a pair of small wings, and see a proboscis and a pair of long antennæ. +Also the six long legs of the future butterfly can be traced with care. + +The abdomen is conical in form, coming to a sharp point at the end, and +its segments are quite distinct. + +No stranger to the metamorphoses of insects would connect the present +form with that of a caterpillar; they are so very unlike. And yet the +time occupied in the whole change, from the spinning of the carpet, does +not occupy more than about thirty or thirty-five hours. + +The apparent suddenness of this change is really surprising, but in +reality the transformation is not nearly so sudden as it appears. +Dissection of a caterpillar a few days before the final moult is due +will show that the changes are already going on. In fact, a simple +removal of the skin will prove that the organs of the future butterfly +are developing. Still, in proportion to the short time occupied, the +change is extremely great; and it may reasonably be inquired, Why so +great a change within so short a space of time?--why is not the change +continued steadily and equally through the larval existence? The reason +has already been hinted at. Caterpillars are living eating machines, +whose office is to remove excess of vegetable matter. Consequently they +must have their jaws and bulky digestive apparatus in full development +to the end. If these organs were to _gradually_ disappear as the +caterpillar reaches its non-eating stages, it would simply be starved to +death. So the change from the larval to the pupal state, which we may +regard as the final moult of the caterpillar, is a far greater change +than any of the preceding ones, and occupies a proportionately longer +time, although it is principally confined to the last few days of the +caterpillar life. + +A number of caterpillars, and especially those of the butterflies, +suspend themselves when about to change; and the peculiarities of the +modes adopted must be left for our descriptions of species in a future +chapter; but we will find room here for one more interesting example, +taking this time the larva of one of the commonest of the Vanessas (page +166)--the Small Tortoiseshell Butterfly. + +The caterpillars of this insect are gregarious when young; and if ever +you meet with one, you are almost sure to be able to obtain a hundred or +so without much searching. But as they grow older they feed singly, yet +generally without straying very far from their birthplace. + +When full grown they sometimes stray to a neighbouring plant or fence to +undergo the change to a chrysalis, but more commonly they are perfectly +satisfied with the protection afforded by the leaves of their food +plant. We will now watch one of these as we did the larva of the Large +White Butterfly. + +Of course the under side of the leaf is chosen. Here a silken carpet is +spun as before described; but the caterpillar, instead of clinging with +_all_ its claspers, suspends itself in a vertical position by its +hindermost pair only. + +Here it hangs, head downwards, awaiting the coming events. The splitting +and casting of the skin goes on just as in the case of the Large White, +but there is this puzzle to be solved: how can the insect shuffle itself +out of its old coat without falling to the ground, leaving the cast-off +garments still hanging by the hooks of the claspers? This really seems a +matter of impossibility, since the little hooks which alone suspend the +insect are thrown off with the skin of the claspers. + +The thing is managed in this way. As the skin slowly splits through the +wrigglings of the apparently uncomfortable occupant, it is gradually +pushed backward--that is, upward--till it is in a shrivelled condition, +and the body of the insect is nearly free. But the chrysalis thus +brought to light is provided with little hooks on the end of its 'tail' +by which it can attach itself to the irregularities of the crumpled +coat. Its conical abdomen is also very flexible, and it can, by bending +this, seize hold of a ridge in the skin, holding it between the +segments. Thus, although practically quite free from the old garb, it +never falls to the ground. + +There is now, however, another point to be attended to. The newly formed +chrysalis desires to be entirely independent of its cast-off skin, and +to suspend itself directly from the silky carpet it has prepared. To +this end it works steadily for a time, alternately bending its supple +abdomen from side to side, gripping the folds of the skin between the +segments, pulling its body a little higher at each movement, and +securing itself at each step by the little hooks at its extremity. + +So it climbs, and at last it reaches the network of silk fibres, and +thrusts the tip of its abdomen among them till some of the hooks have +taken hold. Not satisfied with this, it turns its body round and round +to get the little hooks so entangled between the silk fibres that a fall +is impossible, and in so doing it frequently pushes the old skin out of +its place so that it falls to the ground. + +Although the caterpillars of this species do not show any great +gregarious tendency when nearly full fed, yet it is not an uncommon +thing to find several hanging from the under surface of one leaf, all +being attached to the one common carpet at which all had worked. And +when bred in confinement, a number will often spin in company in a +corner of their cage. I have thus obtained a cluster of thirty-seven +pupæ, all hanging by the 'tails' to the same mass of silk, which was so +small that they formed quite a compact mass of beings with their tails +close together. + +[Illustration: FIG. 28.--THE COCOON OF THE EMPEROR MOTH.] + +[Illustration: FIG. 29.--THE COCOON OF THE SIX-SPOTTED BURNET +(_Filipendulæ_).] + +We have seen that the Large White Butterfly makes itself secure by a +silk band round its middle, while the 'Tortoiseshell' is fixed only by +its tail. But the extra provision for the safety of the former is not so +necessary in the case of the latter, as it never spends more than two or +three weeks in the pupal state. Here it is the perfect insect that +braves the winter, and not the chrysalis. + +There is a great variety in the means taken by the caterpillars of moths +to protect themselves during their metamorphoses, but we shall have +space for only a few illustrations. + +A clever cocoon is spun by the larva of the Emperor Moth (_Pavonia_). It +is pear-shaped, and composed of a brownish silk; and is so constructed +that the newly emerged moth can easily walk out of the small end without +breaking a fibre, while the entry of an insect enemy from without is +impossible. + +This is managed as follows. A number of rather stiff threads are made to +project from the small end of the cocoon, and these converge as they +pass outward so that the ends are all near together. The other portions +of the cocoon are of compact silk, and any insect intruder that ventures +to enter by what we may almost term the _open_ end is met by a number of +spikes, as it were, that play on it at every attempt. Many of these +wonderful cocoons may be found during the winter months attached to the +food plants of this insect. + +Of the silken cocoons spun by various caterpillars some are so thin and +light that the chrysalis can easily be seen through them, and others are +so densely woven as to be quite opaque. A great difference is also to be +observed in the adhesive power of the silk fibres. In some cases little +threads of silk can be pulled off the cocoon; but some of them, that of +the Oak Eggar (page 229) for example, look as if they had been +constructed of paper rather than of silk, because, at the time of +spinning, the moist silk fibres stuck so closely together. + +An extreme case of this character is to be met with in the cocoon of the +Puss Moth (page 235); for here the fluid from the spinneret of the +caterpillar does not harden at once on exposure to air, and so the +threads become thoroughly united together, thus forming a solid gluey +cocoon. + +When the Puss caterpillar is about to change, it descends the tree +(poplar, willow, or sallow) till it is within a few feet of the ground. +Then it commences gnawing away at the bark, at the same time cementing +all the pieces together with the gluey substance from its spinning +glands. In this way it surrounds itself with a very hard cocoon, which +so closely resembles the surrounding bark in colour that detection is +difficult indeed. + +But how will the caterpillar proceed if it is removed from its native +tree and has no bark to gnaw? That you can easily answer for yourself, +or rather Puss will answer it for you. Go and search among the poplars, +willows and sallows in the month of July. You may possibly come across a +caterpillar that is just in the act of creeping down the bark in search +of a resting place; but if not you may be successful in obtaining a few +either by examining the twigs, or you may start them from their hiding +places by smartly tapping the smaller branches with a strong stick. + +Having secured one or more larvæ, take them home, and they will give +some rather novel performances. If they are not fully grown, you must +supply them with fresh leaves every day till they refuse to eat; and +then is the time for your experiments. Shut one in a little wooden box, +and you will have the pleasure of watching it construct a cocoon of +chips of wood that it has bitten out with its powerful jaws, all joined +together into a hard shell by means of transparent glue. Shut another +Puss in a glass vessel--a tumbler, for instance--either by placing it +under the inverted vessel, or by covering over the top. Perhaps it will +not be superfluous to mention that, should you place it under an +inverted vessel, this vessel should not stand on a polished table, for, +whatever be the material, unless _extremely_ hard, it is sure to be +utilised in the manufacture of the cocoon. + +Let us suppose, then, that the caterpillar is under an inverted tumbler +that stands on a plate or saucer. Now it is for _you_ to decide what +material shall be used in the construction of the new home. Give Puss +some fine strips of brightly coloured ribbon, and it will construct a +very gaudy house by gluing them together. Or, provide it with sawdust, +pieces of rag, glass beads, sand, paper, anything in fact; and the +material will be 'made up' into a cocoon more or less ornamental +according to the nature of the supply. + +But what if you give it _nothing_ with which to work, and so inclose it +that nothing its jaws can pierce is within its reach? For instance, shut +it in with tumbler and saucer as before, inverting the former on the +latter, and give it no material whatever. What will it do now? We will +watch and see. + +At first it is very restless, and walks round and round the edge of the +tumbler, evidently a little dissatisfied with the prospects. Then, after +a little while, the events of nature transpiring in their fixed order +regardless of trivial mishaps, the glutinous fluid begins to flow from +the creature's spinning glands, and it moves about in a somewhat aimless +fashion, applying the transparent adhesive matter both to tumbler and +saucer. + +It seems now to become a little more reconciled to its unnatural +surroundings; and, making the best of bad matters, keeps its body in one +place, and starts the construction of a ridge or barrier all round +itself. By the continued application of the creature's spinneret this +barrier is made gradually thicker and higher, till at last the +overhanging sides meet and the caterpillar is inclosed in its +self-constructed prison. But the walls of this prison are so transparent +that every movement can be watched; and, after the insect has spent a +few days in completing the cocoon, we can see it cast off its old skin, +and appear in the new garb of a fine greenish chrysalis. + +Its soft green skin soon hardens and turns to a rich dark brown colour, +and it settles down for a long rest lasting till the following May or +June. + +When the whole operation of building is completed, lift up the tumbler, +and up will come the saucer too. The two are firmly glued together by +the substance secreted; and the power of this as a cementing material +will be well illustrated if you endeavour by mere pulling force to +separate the two articles. + +The Puss is not the only caterpillar that works up a foreign material +with the contents of the spinning organs. There are several others, in +fact, that use for this purpose fragments of wood or other parts of the +food plants; and a still larger number bind together leaves, fresh or +dead, or particles of earth or other matter. Several such cocoons will +be described in our accounts of individual species in another chapter. +We shall now devote a little space to a few general remarks on the +chrysalides and the final metamorphosis of butterflies and moths. + + + + +CHAPTER IV + +_THE PUPA OR CHRYSALIS_ + + +As soon as the last moult of the caterpillar is over, the chrysalis that +had already been developing under the cover of the old skin is exposed +to full view; and although the perfect insect is not to be liberated for +some time to come, yet some of its parts are apparently fully formed. + +[Illustration: FIG. 30.--THE PUPA OF THE PRIVET HAWK (_Ligustri_).] + +[Illustration: FIG. 31.--THE CHRYSALIS OF THE LARGE WHITE BUTTERFLY +(_Brassicæ_).] + +The newly exposed skin of the chrysalis is very soft and moist, but as +it hardens it forms a membranous or horny covering that protects and +holds firmly in place the trunk and the various limbs and appendages +that are distinctly to be traced on the under surface. + +If, however, you examine a chrysalis directly after the moult is over, +you will often find that the wings, antennæ, proboscis, and legs of the +future butterfly can be easily separated from the trunk of the body on +which they lie by means of a blunt needle, and can be spread out so as +to be quite free from that surface. + +In form the chrysalides of butterflies and moths are as variable as the +caterpillars. Many of the former are sharply angular like that of the +'Small Tortoiseshell' already mentioned; but some of the +butterflies--the Skippers (page 197)--have smooth and tapering +chrysalides, and so have most of the moths. + +In colour they are equally variable. Some are beautifully tinted with +delicate shades of green, some spotted on a light ground, some striped +with bands more or less gaudy and distinct, but the prevailing tint, +especially among the moths, is a reddish brown, often so deep that it is +almost a black. + +[Illustration: FIG. 32.--THE PUPA OF THE DARK GREEN FRITILLARY +(_Aglaia_).] + +[Illustration: FIG. 33.--THE PUPA OF THE BLACK-VEINED WHITE BUTTERFLY +(_Cratægi_).] + +As a rule there is no marked resemblance between the different stages of +the same insect. Thus, a brilliantly coloured caterpillar may change to +a dull and unattractive chrysalis, from which may emerge a butterfly or +moth that partakes of the colours of neither. But in a few cases there +_are_ colours or other features that remain persistent throughout the +three stages, or show themselves prominently in two. + +An interesting example in point is that of the Magpie or Currant Moth +(page 279). The caterpillar of this moth is cream-coloured, with orange +stripes along the sides, and very bold black markings down the back. The +chrysalis, which is at first entirely yellow, afterwards turns black +with the exception of some yellow transverse bands. Then, the moth +exhibits the same colours as these two earlier stages, with the same +degree of boldness; for its pale cream-coloured wings, tinted with +patches of yellow, are marked with numerous deep black spots. Thus, in +this case, we find the same general character of the colouring +throughout the insect's existence. + +[Illustration: FIG. 34.--THE PUPA OF THE CURRANT MOTH.] + +[Illustration: FIG. 35.--PUPA OF THE PALE TUSSOCK MOTH (_Pudibunda_).] + +Another interesting example, though not so striking as the last, is to +be found in the case of a group of moths known as the _Liparidæ_. The +caterpillars of these are remarkable for their very hairy bodies, often +ornamented by several bold brush-like tufts. The chrysalides are also +hairy; and several of the moths themselves are not only thickly clad +with shaggy hair, but a bold tuft often tips the abdomen. + +We must not leave these few remarks on the characters of chrysalides +without a mention of the brilliant spots of burnished gold that decorate +the pupæ of certain butterflies. This is the feature that led to the +invention of the term _chrysalis_, which is derived from the Greek word +_chrysos_, meaning _gold_. For the same reason the term _aurelia_ has +been applied to the pupæ of _Lepidoptera_, this being derived from +_aurum_--the Latin name for gold. + +Strictly, then, these two terms apply only to the pupæ of a certain +number of the butterflies; but the former is now generally used to +designate the pupæ of all the _Lepidoptera_, and is even extended to the +corresponding stages of insects of other orders. + +If you examine one of these gold-speckled chrysalides, the brilliant +metallic lustre seems to belong to the outer surface, just as if certain +spots had been tipped with real gold; but after the butterfly has +quitted its case the beautiful golden spots are gone. This proves that +the metallic appearance is not due to reflection from the outer surface +of the chrysalis, but to a reflection from some structure beneath it. +This latter is a very thin membrane which lies just under the outer +transparent covering of the chrysalis. + +The period during which the _Lepidoptera_ remain in the chrysalis state +varies very considerably in different species, and also depends more or +less on the temperature. As a rule, when a caterpillar pupates before +the end of the summer, it remains dormant in the pupal condition for +only a few weeks; but, if late in the summer or in the autumn, it +remains in this condition throughout the winter, and emerges in the +following spring or early summer. + +Both these conditions are illustrated in the life history of the Large +White or Cabbage Butterfly--an insect with which we have already become +acquainted. We get two distinct broods of this butterfly every year, the +first appearing in May and the second in August. The eggs of the first +brood hatch in about a fortnight, and the larvæ are full grown about +four weeks later. These then change to chrysalides, from which the +perfect insects (the second brood) emerge in a few weeks--the period +varying slightly with the temperature of the season. From the eggs of +this second brood we get another invading army of cabbage eaters that +change to pupæ late in the summer. These remain dormant till the +following April, and may be found in numbers throughout the winter, +attached to the walls and fences of kitchen and market gardens. + +If, then, the pupæ of the same species are so influenced by the +temperatures of the seasons, can we limit or prolong the period of +quiescence by subjecting them to high or low temperatures artificially +produced? Most certainly we can; and every practical entomologist knows +how to obtain the perfect butterflies and moths of certain species long +before their appointed times, or, if he desires it, to compel them to +remain in their dormant stage long after the natural period has +terminated. + +Sometimes an enthusiastic insect hunter obtains a large number of what +we may term 'winter pupæ,' by collecting and breeding various species. +He also anticipates a number of successful captures of perfect insects +during the following summer. Thus, from two distinct sources, he obtains +a goodly assortment of butterflies and moths, the setting, preserving, +and arranging of which entails an immense amount of home work. + +Under such circumstances he will sometimes endeavour to cause some of +his pupæ to emerge before their accustomed time, so that he may get some +of his insects 'on the boards' before his field work is in full swing, +and so avoid a rush, or prevent the loss of insects that will be spoiled +before he has time to take them in hand. + +This process of hurrying up his pupæ he calls 'forcing,' and simply +consists in keeping them for a time in a warm room or hothouse where the +high temperature is pretty constant. + +On the other hand, the entomologist may desire to try the effect of a +continued _low_ temperature on his pupæ. This he can do by placing his +pupæ in an ice house. Such experiments have often been performed, and +the results are very interesting. In some cases the emergence of the +perfect insect has been delayed for many months, and even years; and +then, after an exposure to a normal temperature lasting only a week or +two, the winged insect has made its appearance just as if nothing +unusual had happened. + +Such are the effects of _extreme_ temperatures on the duration of the +chrysalis state; and we naturally infer, from such results, that the +pupa under natural conditions is influenced, though in a lesser degree, +by the variations experienced with the seasons, especially in such a +fickle climate as our own. + +The insect hunter has always to bear this in mind, and particularly so +when he sets out on a search for certain desired species. Suppose, for +example, he has set his mind on the capture of a certain butterfly that +_usually_ appears in the _first_ week in May. Before finally naming the +day, he has to consider what the weather has been during the last few +weeks, and if he finds that this has been much warmer than the average +for the corresponding periods in the past, he selects a day in _April_, +earlier or later according to the difference between the present season +and the average. + +If he does not pay due attention to such considerations, he will +sometimes find that all the insects netted are shabby and much worn, +even though, under average conditions, he would be catching newly +emerged and brilliant specimens. This, then, will explain how it is that +we so often see in entomologists' periodicals startling accounts of +'early captures,' and of the appearance of certain insects late in the +season that _ought_ not to have emerged till the following summer. + +I will give just one illustration of these variations. The beautiful +Orange Tip Butterfly (Plate I, fig. 7) generally appears about the +middle of May in the southern counties. Farther north it is of course a +little later. In the north of England it has been taken in June; and in +Scotland as late as July. On the other hand, I have taken it in +Gloucestershire as early as March, on a rather bleak day with a cold +east wind; and, withal, in a field on the slope of the Cotswolds fully +exposed to the unfavourable breeze; but it was evident that, in this +case, the butterfly had been enticed from its winter quarters by the +milder weather of the few previous weeks. + +It may be as well, in passing, to observe that it is not only the pupa +that is influenced by temperature. The hatching of eggs may be forced by +high temperatures, or be retarded by exposure to cold; and in nature the +period of incubation varies with the seasons. The larvæ, too, grow +faster or more slowly, or pupate earlier or later from similar causes. +And so no very definite date or period can be assigned to any one stage +of any insect. + +Now let us return to one of the chrysalides that we have already watched +through the earlier stages of its existence, and follow it in its future +development. + +It is now, as we say, in its quiescent or dormant condition, but we must +not suppose that it is always in a profound sleep, nor can we say that +it is insensible to its surroundings. Touch it gently or surprise it +with a puff of air from your mouth, and it will begin to wag its pointed +tail, sometimes with such vigour as to send the body rolling round and +round in its box. Lay it on a bed of cocoa-nut fibre or finely sifted +soil and let it remain _quite undisturbed_ for a few hours or days, and +you will probably find that, by occasional movements of its body, it has +made a slight depression in its bed, and lies partly submerged. I have +known some chrysalides to completely bury themselves in this way during +the course of a day or two, and others to partly expose themselves after +having been lightly covered. Others again, I have observed, will move +smartly if a strong light is suddenly turned on them. Many, too, +certainly appear to have a strong objection to exposure to the direct +rays of a hot sun; for, when thus exposed, they will struggle +persistently, as if to work their bodies into some shady corner. I would +not advise a young entomologist to try this experiment, however, if he +values the pupæ he possesses, for direct sunlight is undoubtedly very +harmful to many species, and perhaps it is to all. + +Some chrysalides are not nearly so active as has just been represented; +in fact, there are many which seem to show no signs of life during the +greater part of the time spent in that state. But in all, whether +apparently active or not, certain important internal changes are at +work. We have already noticed that, even in the last days of the +_larval_ existence, some of the organs of the future imago are to be +traced. But these are as yet imperfectly developed. We have also +observed that a continuation of these changes, gradually carried on, +would be impossible in a voracious feeder; so the insect, now fully +grown, and no longer requiring a supply of food, settles down in perfect +quiet, submitting itself quite passively to any further changes that +nature may demand. + +It has already suffered the loss of its claspers. Its wonderful jaws +that did so much damage (for good or evil as the case may be) to the +vegetable world are now gone, and the bulky digestive apparatus has +rapidly dwindled to useless dimensions. These and other changes, already +in progress, have to be perfected while the creature is in a restful and +helpless condition, though they may often be retarded or even suspended +during cold weather when progress would certainly bring it to an +untimely end. + +But now the grandest of all these transformation scenes is nigh at hand. +The protective skin is already loosening from the almost perfect imago, +and consequently feels softer and far more yielding than it did when in +close contact with the body: the swaddled butterfly or moth (for such +the pupa is) is slowly preparing to throw off its imprisoning garb. The +wings and large compound eyes are assuming their final colours, which +now begin to show themselves through the more or less transparent skin, +and the long legs, the perfectly formed antennæ, and the slender +proboscis, all of which are folded closely under the creature's thorax, +now begin to move within their loosened sheaths. + +Now let us watch it closely, for one of the most wonderful sights ever +witnessed by a naturalist is about to be presented to our view. We think +we can observe slight movements; and, it may be, we can actually see the +struggling insect endeavouring to set itself free. The legs and +proboscis are moving within the loosened skin; and lo! as we watch these +motions, the prison wall bursts with a slight snapping noise (at least, +such is the case with some of the larger species), and in a moment out +pop a few long legs which immediately struggle for a foothold. The +proboscis also appears, alternately lengthening itself out and coiling +into a spiral, as if impatient to reach the sweet nectar from the bottom +of some fragrant flower cup. + +[Illustration: FIG. 36--A BUTTERFLY, JUST AFTER EMERGING.] + +All this takes place in less time than one requires to describe it; and, +before many seconds have passed, the struggling insect has quite +completed its last moult, and is bidding good-bye to the rent garment +that has done it good service for so long a time. + +But how dreadfully disappointing! Did we not say only a few minutes +since, that a beautiful butterfly or moth was about to emerge? How, +then, is this? Here is an odd-looking creature, such as we have never +seen before! True, it has the right kind of body, though even that is so +soft and heavy that it is fairly dragged along as the insect walks. Its +antennæ, too, seem to be just the right thing--that is, just what we +were expecting to see. But oh! the wings! Are we looking at a +deformity?--a failure on the part of Nature to produce what she ought? + +We will not judge hastily, but continue to watch it a little longer. It +seems very restless at first, and, with the fluttering apologies for +wings, drags its heavy body along till it reaches some surface up which +it can climb. If nothing of the kind is close at hand you may place a +_rough_ upright stick in its path, and it will immediately begin to +ascend. Its motto is now 'Excelsior!' and its ambition to rise may be so +great that, on reaching the very top of the stick provided for it, it +struggles for a still higher position in life till, failing to get a +foothold in the air itself, it falls to the ground and has to retrace +its steps. + +I once thought I would like to test the perseverance of a large moth in +performing its first upward journey; and as it was one from a chrysalis +to be found in nature at the foot of a tree that attains some +considerable height, I was, of course, prepared to exercise a little +patience myself. + +As soon as the moth had emerged, I placed it at the bottom of a window +curtain that hung from about eight feet high to the floor. In less than +half a minute it had reached the top, and was struggling hard to get +still higher. I took it down, and again placed it at the bottom. Up it +went as fast as before; and this was repeated nine times with exactly +the same result. For the tenth time I placed the persevering creature at +the bottom of the curtain; and, after it had walked about halfway up, it +_suddenly_ stopped, apparently quite satisfied with having travelled a +distance of over seventy feet in an upward direction. Its six legs were +immediately arranged symmetrically in a business-like manner, and there +it settled quite still, as if it had some definite object in stopping +just exactly in that spot. + +But we must now return to our own insect, which has by this time settled +itself in a similar manner on the stick we provided for it. The peculiar +organs which represent the wings, though so very small, show distinctly, +in miniature, the colour and pattern of the fully developed wings of the +species. An interesting change is just now commencing. These wings are +apparently growing larger, but the development is very unequal, so that +they become curled and crumpled till they are even more unsightly than +before. All seems to be going amiss. But this lasts only for a short +time. The fluid from the body steadily rushes into the _nervures_, +causing the wings to expand, and in a few minutes the beautiful pinions +are stretched to the full extent, assume their normal shape, and expose +the full glory of their brilliant colours. + +It may be interesting if I give an example showing the exact time taken +for the full development of the wings of a certain insect. So I will +here quote an entry from my note book; and, by the way, let me strongly +advise all my young readers who follow up this subject to habitually +enter in a book kept specially for the purpose all facts which strike +them as they pursue their study of nature. The note to which I refer +runs as follows: + +'Early on the evening of the 22nd [April] I selected a few chrysalides +of Populi [the Poplar Hawk Moth, page 209] which, from the looseness of +their cases, were thought to be just on the point of emerging. At 8.46 +one of them showed signs of restlessness; and, after a few vigorous +movements, during which it rolled itself over on the glass [I had placed +the pupæ on a piece of plate glass so that slight movements might be +more easily detected], the front of its case was suddenly thrust off +with considerable force; and in _less than four seconds_ the imago was +quite free and crawling on the table. After trying hard to reach a +higher point than was provided for about four minutes, it rested to +expand its wings--now about seven-sixteenths of an inch long, or +one-third the total length of the body. At 9 o'clock the wings reached +half the length of the body, and were much curled. At 9.12 they were +fully expanded and straightened out.' + +From this extract we see that the whole period from the bursting of the +case to the full expansion of the wings was only twenty-six minutes; and +it will be well to remind the reader that the process occupies even a +much shorter time than this with many species, both of butterflies and +moths. It will be observed, also, that the _evening_ was chosen as the +time for the observation. There was a reason for this. The Poplar Hawk +Moth, as is the case with many others, almost invariably emerges from +the chrysalis in the evening--usually after dark. But it may be +mentioned in passing that a far larger number of the _Lepidoptera_ as +invariably emerge in the morning. + +Again we will return to our newly emerged insect, for there are still +one or two interesting points to observe. The wings have fully expanded, +it is true, but how very limp they are! Take the creature on the tip of +your finger and hold it so that its body is in a horizontal position. +Immediately the wings bend downward with their own weight, so soft and +flexible are they. The body, too, is still very soft, and apparently +much too heavy for flight. Then, if you place it on a flat surface, it +will immediately try to find some perpendicular or overhanging surface +from which it can suspend itself by means of its legs, so that the +pendant and straightened wings are in the best possible position for +drying. As the insect walks away in search of such a resting place, the +body still drags as it did before, and the wings bend over, either both +on one side or one on each side of the body. + +It is some time before the wings are sufficiently dry and rigid for +flight, but the period varies greatly with different species. Some of +the small butterflies and moths take to flight long before an hour has +passed, but in many cases several hours elapse before the creature +starts from its first resting place. Butterflies that emerge in the +morning spend their first day actively on the wing; but the nocturnal +moths that emerge early in the day do not fly till evening twilight. +When, however, the time arrives, the insect flutters its wings as if to +test their power before committing itself to the air; and frequently, +after only a few seconds spent in this preparatory exercise, off it +darts with astonishing rapidity. But others seem far more cautious. They +vibrate their wings, sometimes with such rapidity that they are lost in +a kind of mist, and with such power that their bodies would be carried +suddenly into the air were they not firmly anchored by three pairs of +hooked claws. Then, continuing the rapid vibration, they move slowly +along, always holding on firmly by one or more legs, as if to still +further satisfy themselves concerning the efficiency of their wings. +Then they venture on a few short trial trips from one neighbouring +object to another, and at last gain sufficient confidence for a long +voyage. + +How strange must be the feelings of a winged insect during its first +flight! After a long period during which it was a helpless, crawling +grub, and this followed by a term of imprisonment during which it was +almost or quite shut off from the world, it now suddenly acquires such +great powers of locomotion that it is often a match for ourselves. + +But, alas! this life is short. A few days spent in sporting with those +it meets and in sucking the sweet juices of many flowers; then a day or +two during which the female deposits its eggs; again a few days employed +in pleasures that become less and less attractive, till, at last, the +creature becomes weary of life and settles down to die. + +We have now traced the complete life history of the _Lepidoptera_ from +the egg to the perfect insect, avoiding descriptions that apply only to +certain species as far as possible, excepting where such are useful as +illustrations. + +Only one thing more remains to be done before we start in real earnest +with our practical work. We shall shortly be giving hints on the modes +of capture, the 'setting' and the preservation of butterflies and moths. +And in so doing we shall often have to observe important points in which +our dealings with these two great divisions of the order will differ +very materially. Hence we must not consider ourselves ready to proceed +with the practical portion of the entomologist's labours till we are +perfectly satisfied that we know the main features that enable us to +distinguish between the butterflies and the moths, and also know just a +little concerning the subdivisions on each side. + +This, then, shall form the subject of the next short chapter. + + + + +CHAPTER V + +_CLASSIFICATION OF THE LEPIDOPTERA_ + + +The _Lepidoptera_ are divided into two very unequal groups, to which we +have so frequently alluded as 'Butterflies' and 'Moths.' And, although +these two terms are popularly applied in a fairly accurate manner, yet, +strange to say, very few persons indeed have any definite knowledge of +the differences that entomologists recognise between the two groups. + +Every entomologist has his circle of sympathetic and, perhaps, even +admiring friends. Consequently, many a little package is sent round to +his abode 'with great care,' accompanied by a note or a message +concerning the fine 'butterfly I have just caught, and thought you would +like to add to your collection.' + +The 'butterflies' that so frequently reach us through these channels +nearly always turn out to be _brightly coloured_ moths, and this +naturally gives one the idea that the popular notion as to the +classification of the _Lepidoptera_ is based on colour or brilliancy of +design, the term 'butterfly' being applied to the gayer species, and +'moth' to the more dingy members of the race. + +There is really some shadow of a reason in this method of nomenclature, +for butterflies _are usually_ more brightly clad than moths; but the +scientific classification, at least as far as the main divisions and +subdivisions are concerned, has nothing whatever to do with colour or +design; and we must at once acquaint ourselves with the fact that there +_are_ very dingy butterflies, and most beautiful and highly coloured +moths. + +How shall we account for the fact that the specimens so kindly sent us +by our friends are generally moths? Is it because moths are more +numerous and more frequently seen? They are certainly more numerous; +for, while our butterflies do not number seventy species, the other +division contains about two thousand. Yet, in spite of this fact, moths +are not generally observed as much as butterflies, for the former are +nearly all night-fliers, and the latter _always_ fly by day and rest by +night. + +Still our question remains unanswered. The reason is this. The captives +sent us are seldom caught on the wing. Most of our grown-up friends, +even though they admire our own pluck and general carelessness +concerning the remarks of the spectators of our entomological antics, +would not themselves like to be seen, hat in hand, chasing a butterfly; +and the night-flying moths are, of course, less frequently observed. But +they often, in the course of their daily employments, meet with a large +moth fast asleep in some corner of a dwelling house, workshop, or +outhouse. Such moths are easily caught while in the midst of their +slumbers, and, as they often make no attempt to fly by day, are as +easily transferred to a box suitable for transmission by messenger or by +post. + +In the above few remarks we have alluded to some features by which the +two great groups of the _Lepidoptera_ may be distinguished; but we have +already referred (page 5) to a far more important one in our description +of the various forms of antennæ. All butterflies--at least all _British_ +butterflies--have knobbed or clubbed antennæ, while the corresponding +organs of all our moths terminate in a sharp point. + +This distinction obtains in all British _Lepidoptera_, and is so far +regarded as the most important basis of classification that naturalists +have derived from it the two Greek terms that are synonymous with our +two popular names--butterflies and moths. The scientific name for the +former group is _Rhopalocera_--a term derived from two Greek words, one +signifying a horn, and the other a club, and thus meaning 'club-horned.' +The corresponding name for moths is _Heterocera_, derived from the same +source, and meaning 'variously horned.' + +But, although we find embodied in these two long and formidable names an +unerring mark of distinction between British butterflies and moths, we +must not neglect other less important facts which, though less +distinctive, are not without interest. + +Observe a butterfly at rest. Its wings are turned vertically over its +back, and brought so closely together that they often touch. In this +position the 'upper' surfaces of the 'upper' wings are completely hidden +from view, and the 'under' surfaces are exposed on the two sides, +except that those of the 'upper' pair are partly hidden by the other +pair. + +Now look at a moth under the same circumstances, and you will generally +find the wings lying over its body, which is almost or completely hidden +beneath them. As a rule the upper pair together form a triangular +figure, and entirely cover the second pair; but in some cases a portion +of each of the under wings extends beyond the margin of those above +them, and in others the upper pair extend so far forward that nearly the +whole of the under wings is exposed behind them. + +[Illustration: FIG. 37.--A BUTTERFLY AT REST (LARGE COPPER).] + +[Illustration: FIG. 38.--A MOTH AT REST (GOTHIC).] + +Again, the wings of butterflies are so rigid that they can never be +folded; but you will observe that the under wings of moths are generally +very thin, soft, and pliant, and are neatly pleated lengthwise when not +in use. + +Another feature deserving notice is a slight difference to be often +observed in the form of the body. The butterfly, which generally has a +slender body, has a distinct constriction or waist between the thorax +and abdomen. This is not so apparent with moths, and especially with the +thick-bodied species. + +The _Rhopalocera_ or Butterflies are divided into _Families_, each of +which contains insects that possess certain features in common by which +they may all be distinguished from the members of any other family. + +The British species represent eight families. They are as follows: + +1. _Papilionidæ._--Containing only one British species--the beautiful +Swallow-tail (Plate I, fig. 1). + +2. _Pieridæ._--Containing ten species. These are often known +collectively as the 'Whites,' but include four butterflies that are +distinguished by beautiful shades of yellow and orange. + +3. _Nymphalidæ._--This family contains seventeen insects, among them +being several splendid species. It includes the Fritillaries and +Vanessas. + +4. _Apaturidæ._--Of this we have only one representative--the Purple +Emperor (Plate V, fig. 1). + +5. _Satyridæ._--Including the 'Browns' and 'Heaths,' and numbering +eleven species. + +6. _Lycænidæ._--Including the Hairstreaks, 'Coppers,' and 'Blues,' in +all seventeen species. + +7. _Erycinidæ._--Containing only the 'Duke of Burgundy.' + +8. _Hesperiidæ._--This family contains seven British butterflies +commonly known as the 'Skippers.' + +Although all the members of the same family resemble each other in +certain points of structure, or in their habits, yet we can often find +among them a smaller group differing from all the others in one or two +minor particulars. Such smaller groups are called _Genera_. + +To make this all quite clear we will take an example. + +The Brimstone Butterfly (Plate II, fig. 4) belongs to the second +family--_Pieridæ_, _all_ the members of which are distinguished from +those of the other families by the characteristics mentioned on page +141. + +But our Brimstone Butterfly possesses another very prominent feature in +which it differs from all the other British _Pieridæ_, and that is the +conspicuous projecting angles of both fore and hind wings. Among the +foreign species of the family we are considering there are several that +possess these angles; but as there are no others among our own members, +the 'Brimstone' is placed by itself in the list of British _Lepidoptera_ +as the only member of the genus _Gonopteryx_ or 'angle-winged' +butterflies. + +Thus the full relationship of this butterfly to other insects may be +shown in the following manner: + + _The Brimstone Butterfly._ + + =ORDER.=--_Lepidoptera_ + =Section.=--_Rhopalocera_ + FAMILY.--_Pieridæ_ + _Genus._--_Gonopteryx_ + Species.--_Rhamni_ + +Now, every butterfly has a Latin or Greek name in addition to that by +which it is popularly known. I should have said _two_ Latin or Greek +names. The first of these is always the _generic_ name, and the second +is the one by which we denote the particular member or _species_ of that +genus. Thus, the scientific name of the Brimstone Butterfly is +_Gonopteryx Rhamni_. + +'But,' the reader may be inclined to ask, 'why should we not be +satisfied with the one popular name only?' And, 'If we _must_ have a +separate scientific name, could we not find suitable terms among our +English words to build up such a name--one that might express the +principal characteristics of the insect, and also serve all the purposes +of classification?' + +Such questions sound very reasonable, and so they are. But the +entomologist's answer is this. We ourselves may get on well without the +help of the dead languages, but we have brother naturalists all over the +world, speaking a great variety of different languages. We endeavour to +help one another--to exchange notes and generally to assist one another +in our labours; and this can be greatly facilitated if we all adopt the +same system of nomenclature. The educated of most of the great nations +generally know something of Latin and Greek, and consequently the +adoption of these languages is generally acceptable to all. + +This sounds well, but for my own part I believe that if we are to make +any branch of natural history a popular study, especially with the +young, we must to a certain extent avoid anything that may prove +distasteful. There is no doubt whatever that many a youngster has been +turned away from the pursuit of the study of nature by the formidable +array of almost unpronounceable names that stretch nearly halfway across +a page; and those who desire to make such a study pleasant to beginners +should be very cautious with the use of these necessary evils. One would +think, on glancing over some of the scientific manuals that are written +'especially for the young,' that the authors considered our own too mean +a language for so exalted a purpose, for in such works we find all or +nearly all the popular names by which the schoolboy knows certain +creatures he has seen entirely omitted, and the description of a species +appended to a long Latin term that conveys no idea whatever to the +reader, who is studying the description of a well-known animal or plant +and doesn't know it. + +Our plan will be to give the popular names throughout, except in the +case of those few species that are not so well known as to have +received one; but the scientific names will always be given as well for +the benefit of those readers who would like to know them. And the short +description of the method of classification just given will enable the +more ambitious of my readers to thoroughly understand the table of +British butterflies and moths toward the end of the book. + +This table includes _all_ the British species of butterflies and of the +larger moths; and the arrangement is such as to show clearly the +divisions into sections, families, &c. It will therefore be of great +value for reference, and as a guide for the arrangement of the specimens +in the cabinet. + +In the foregoing description of the method of classification butterflies +only are mentioned; but the division and arrangement of moths is carried +out in just the same manner except that the system is a little more +complicated. The number of moths is so large in comparison, that we are +able to select from them some very large groups the species of which +possess features in common. These groups are termed _tribes_, and are +again divided into families just like the butterflies. Thus the +arrangement of moths includes _tribes_, _families_, _genera_ and +_species_. We will take an example by way of illustration as we did +before, and ask the reader to verify the same by comparison with our +table: + + _Example._--The 'Common Tiger' (Plate X, fig. 3). + + =ORDER.=--_Lepidoptera_ + =Section.=--_Heterocera_ + TRIBE.--_Bombyces_ + FAMILY.--_Cheloniidæ_ + _Genus._--_Arctia_ + Species.--_Caia_ + Scientific Name.--_Arctia Caia._ + +I have already said that the Latin and Greek names of butterflies and +moths are not at all necessary to the young entomologist. It is quite +possible to be well acquainted with the natural history of these +creatures, and to derive all the pleasure and benefits that the study of +them can afford without the knowledge of such names; but most +entomologists go in for them, often to the entire exclusion of the +popular English terms. + +There are those who consider themselves (or would have us consider them) +expert entomologists because they have the power to vomit forth a long +list of scientific names of butterflies and moths which (to them) have +no meaning whatever; and it is astonishing that we meet with so many +youngsters who can rattle away such terms, and, at the same time, are +totally ignorant of the real nature of the creatures they name. + +If you wish to be a naturalist in the true sense of the term, study your +_specimens_, and take but little pains to commit their hard names to +memory; and you will then find that the latter will gradually become +your own property without any special effort on your part. Your +continued reference to illustrated works and museum collections will +bring them to you almost unconsciously, and you will generally find your +entomological vocabulary extending as rapidly as your cabinet becomes +filled. + +Again, with regard to the _meanings_ of the scientific terms, don't +trouble much about them. It unfortunately happens that in a very large +number of cases these names are ill chosen, and do not in any way refer +to the distinguishing characteristics of the species to which they are +applied. You will observe, too, if you look at the table, that many +insects have _two_ scientific names applied to the species, one being +placed in brackets after the other. In such cases both these names are +in common use, having both been applied by independent authorities, and +the insertion of the two will prove an assistance at times. + +It is a common practice with entomologists, in their communications, to +use only the second or _specific_ name of insects. Thus, they would +speak of the Brimstone Butterfly as _Rhamni_, and not _Gonopteryx +Rhamni_. When _writing_ a communication, however, they very commonly +place in front of the specific name the initial letter of the first or +_generic_ name. Thus the full title of the butterfly just mentioned +would be abbreviated to _G. Rhamni_. + +Having said so much concerning the principles of classification and +nomenclature, we will pass on to the practical portion of the +entomologist's work. + + + + +PART II + +WORK AT HOME AND IN THE FIELD + + + + +CHAPTER VI + +_CATCHING BUTTERFLIES AND MOTHS_ + + +It is not at all surprising that entomology should prove such a +fascinating study to the young, and more especially that portion which +deals with the department we are now considering. Butterflies and moths +are among the most beautiful and most interesting of living creatures. +The study of their life history is enchanting, and the creatures +themselves are of such a size as to be conveniently handled and +preserved, and withal occupy so little space that anyone with only +moderate accommodation may possess a fairly typical collection. + +Compare the work of the entomologist with that of one whose hobby is the +study of mammals. The latter has to deal with large and cumbersome +objects, a collection of which requires an enormous amount of space; +and, unless he has the time and means to travel in foreign countries, he +cannot get together a good typical collection of specimens representing +his particular branch, for the few British mammals contain no +representatives of several of the orders into which the class is +divided. + +Entomology is undoubtedly, _par excellence_, _the_ study for youngsters. +It is equally suited to the studious and to those of an adventurous turn +of mind. It leads its follower into the bright sunshine and the flowery +meadows; and with body and mind pleasantly occupied, the joy of living +is deeply felt. The necessary apparatus can be made by anyone. No +dangerous gun is required, and there are no precipitous rocks to scale. +When the autumn flowers fade the year's work of the entomologist is not +done, for the arranging of his cabinet and the demands of his living +specimens keep him more or less actively engaged until the flowers of +the following spring call both him and the insects he loves once more +into the field. And so, season after season, and year after year, he +finds himself engrossed in labours so fascinating that idleness--the +curse of so many of our youths--is with him an impossibility. + +I assume that the readers of this book have a desire to take up the +study of one branch of entomology--that of butterflies and moths--in +real earnest; that they intend not only to _read_ about these +interesting insects, but to _know_ them. And there is only one way in +which one may really get to know living creatures; that is by searching +them out in their haunts, observing their growth and habits, and by an +occasional close examination in order to become acquainted with their +structure. + +Hence I shall in this, the practical portion of the work, give such +information as will assist the beginner in catching, preserving, +rearing, breeding, and arranging the specimens that are to form his +collection. + + +_Catching Butterflies_ + +There was a time when we would try to capture a butterfly at rest on a +flower by a quick sweep of the hand, or, more commonly, by a sharp +downward stroke of the cap. We were led to this action by a mere +childish love of sport, or by a desire to possess an insect simply +because it was pretty. When we succeeded in securing our prize, we +handled it somewhat carelessly, often passing it from one hand to the +other, or boxing it in our closed and perspiring fist till our fingers +were dusted with the pretty microscopic scales of the creature's wings, +and the wings themselves, stripped of all their beautiful clothing, were +merely transparent and veined membranes. Having thus carelessly but +unintentionally deprived the creature of its greatest beauty, we set it +free, often in such a damaged or exhausted condition that the poor thing +could scarcely fly. + +But our childish ideas and inclinations have vanished. Now we would +rather watch the insect than catch it, for we find much pleasure and +interest in its varied movements. And if for purposes of study we +occasionally require to make one captive, we proceed in such a manner as +to preserve its beauty unimpaired. The cap now gives place to a +well-made and suitable net; and we are careful to provide ourselves with +sufficient and proper accommodation for our captives. + +It is probable that many of my readers are as yet unacquainted with the +nature of an entomologist's requirements for field work, so we shall +describe them, confining ourselves at first to those that are required +for a butterfly hunt. + +First and foremost comes the net. This essential portion of your +equipment may be either purchased or constructed by yourself. Very +little skill is required to enable you to do the former. Provided your +pocket is well charged, you may start off at once to the dealer in +naturalists' appliances, and treat yourself to a complete outfit. But +even in this case a little advice may not be out of place. See that what +you purchase is very _strongly_ made. You can get nicely finished nets +constructed on the most convenient principles, made to fold and go in an +ordinary coat pocket, but with _weak joints_. See that you have the most +convenient form of net by all means, but do not go in for convenience +and appearance at the expense of strength and durability. Nothing is +more annoying than to find your net give way just when you are in the +midst of a good day's sport. + +[Illustration: FIG. 39.--A WIRE FRAME FOR A BUTTERFLY NET.] + +[Illustration: FIG. 40.] + +The folding net is certainly very convenient, for you can conceal it in +your pocket while you are walking through town or travelling in a +railway carriage, and thus avoid that contemptuous gaze which certain of +the public are prone to cast on a poor 'bug hunter.' And although such +nets are generally purchased, yet they _may_ be constructed by anyone +who has had experience in the working of metals. But other forms of +nets, equally useful and even stronger, can be made by anybody; and I +will give a few hints on two or three different ways of putting them +together. + +A very simple and strong frame for a net may be made as follows: Get a +piece of stout iron or brass wire about forty inches in length, and bend +it into a circle with the two ends, turned out about two inches each, at +right angles to the circumference as shown in the accompanying sketch. + +Now take a good tough stick, the length of an ordinary walking stick, +and cut out two grooves opposite each other at the end, just large +enough to take the straight ends of the wire. The end of the stick will +now resemble fig. 40 in shape. Place the ends in their grooves, and bind +them tightly to the stick by a good many turns of rather fine wire. + +A frame well made after this fashion is as strong as anything you could +desire, but it has the disadvantage of being always fixed to the handle, +thus preventing the use of the latter as a walking stick when you are +not directly engaged in your entomological work. + +A much more convenient frame may be made by thrusting the ends of a +piece of cane into the two narrow arms of a metal Y. You may purchase +the Y at any of the naturalists' stores, or you can make one yourself if +you know how to perform the operation of soldering. I have always made +mine with odds and ends of brass tubing such as old gas pipes. One piece +must be just the size to fix on the stick; and the other two must fit +the cane tightly. The three pieces must be filed off at the proper +angles, and the doubly bevelled end of the wider tube must then be +flattened down to the width of the smaller ones before soldering. If you +decide to buy one, give the preference to strong brass rather than the +cheaper and more fragile ones made of tinned iron. + +[Illustration: FIG. 41. THE METAL Y.] + +The advantage of such an arrangement over the last frame is evident at +once. The cane, with net attached, can be pulled out of the Y when not +in use, and bent small enough to go in the pocket or a satchel; and the +Y can also be separated from the stick, thus allowing the latter to be +used as a walking stick. + +Some entomologists speak very favourably of what is known as the +'umbrella net'--a large and light net that will shut up like an +umbrella, and may even be made to look very much like this useful +protector, but the possession of such an imitation is somewhat +tantalising in a pelting shower. The ring of this net consists of two +steel springs attached to a couple of brass hinges, one of which is +fixed near one end of the handle, while the other slides up and down in +the gamp fashion. + +One other form of net--'the clap net'--although still occasionally seen, +has had its best days. Two sticks are provided to this one, so that the +two sides of the net may be brought together on the insect; but as both +hands are required to manage it, it is almost surprising that it ever +had any advocates at all. + +When your frame is completed, sew round it a strip of strong calico, to +which the net itself may be afterwards sewn, for the lighter material of +the net is too delicate to stand the constant friction against the metal +or cane frame. + +The material usually employed in making the 'bag' is called leno. It can +be purchased at most of the drapers' shops, and three colours--white, +yellow and green--are usually kept in stock. Measure the circumference +of your net frame, and see that you get sufficient leno to make a good +full net. Suppose, for instance, that the circle of your frame measures +thirty-six inches round, then your leno should be at least forty inches +in length. Fold this double, and then cut out two pieces of the shape +shown in fig. 42, letting the depth of the net be nearly or quite equal +to the width of the material. There is nothing to be done now but to +stitch the bag together and sew it to the calico on the ring. + +[Illustration: FIG. 42.] + +At first you will find the leno rather stiff and harsh, but a damping +and good rubbing between the hands will soften it down; or, if you +prefer it, you may soften the material by a slight washing before +cutting out the net. The latter is perhaps the better plan, for the +washing will remove the objectionable 'dressing' that renders the +material rather hard and stiff. + +Of the three colours mentioned above, green is the one most generally +chosen, because it is more in harmony with the surroundings of a +butterfly catcher; but many prefer the white leno to the green, as the +insects are more easily seen in a net of this colour. Yellow is +certainly not a desirable tint. + +As a rule it will be necessary to kill an insect as soon as it is +captured. This is always the case with butterflies unless you require to +keep them alive either to watch their movements or to obtain eggs. For +this purpose you will require a killing bottle or box containing some +volatile substance. + +The selection of this necessary piece of apparatus is a point deserving +of much consideration, for so many different forms are in use by +different entomologists, and so many advocates each declare that his own +plan is far superior to that of any of the others, that the final +decision is not to be worked out in a moment. The best thing for a +beginner is to try as many as he can, and then, after some considerable +experience of his own, he will be able to decide which apparatus suits +himself best. + +I recommend this because it is impossible to say of any one plan that it +is the best, for that which gives perfect satisfaction to one individual +will often fail to give anything but annoyance in the hands of another. + +To enable my young readers to follow the advice I have just given, I +will describe some of the commonly used killing arrangements and show +how they should be used. + +I will take first the 'cyanide bottle.' This is a wide-mouthed bottle, +containing a very poisonous substance called _cyanide of potassium_. It +is fitted with a good sound cork. The 'cyanide' is a solid substance, +and must be fixed in some way or other at the bottom of the bottle so +that it cannot shake about and damage the butterflies. + +[Illustration: FIG. 43.--THE CYANIDE BOTTLE.] + +A cyanide bottle can be purchased ready for use at the cost of a +shilling or thereabouts; but if you are old enough to be trusted with +deadly poisons, you may buy the 'cyanide' of a chemist who knows you +well and is satisfied as to your intentions, and then prepare your own. +Every entomologist should know how to do this, for the poison loses its +power after some time, and it is not always convenient to leave your +bottle in the hands of a chemist or a 'naturalist' to have it recharged. +This will cost you more than it would to do it yourself, but that is +nothing compared with the annoyance that may result when, the night +before an anticipated butterfly hunt, you are calmly told that 'your +bottle will be ready in a few days.' You can charge it yourself in a few +minutes if you can manage to keep a small supply of 'cyanide' in stock, +and it is ready for use very shortly after. + +Here is the _modus operandi_.--Purchase an ounce or two of the cyanide +of potassium, and immediately put it into a stoppered or well-corked +bottle. Label it at once, not only with the name, but also with the word +POISON in very large and conspicuous letters. This dangerous chemical is +often sold in sticks that look much like certain 'sugar sticks' I was +acquainted with in my younger days; but whether this is or is not the +case with your cyanide, see that the bottle is kept quite out of the +reach of the inquisitive and sugar-loving juveniles of the house. + +The quantity above mentioned is more than you will require for the first +'charge,' but you will soon experience the convenience of having a +supply always at hand for recharging when your cyanide bottle fails to +do its work expeditiously, or when an accident calls for the somewhat +sudden appearance of a new one. + +Now procure a bottle for your work. Its mouth must be wide enough to +take the largest insect you hope to catch, and the widest part of the +bottle need not be much larger. Get a perfectly sound cork to fit it +tightly; and, to insure the more perfect exclusion of air, paint over +the top of the cork with melted paraffin wax. + +Dissolve a few drams of the cyanide in a little water, using a glass rod +to stir up the mixture till the solid has all disappeared; and be +careful that neither the solid nor the solution touches the skin if it +should be in the slightest degree scratched or broken. Now sprinkle +plaster of Paris into the solution, a little at a time, and stir all the +while. As soon as the mixture begins to set, pour it into your bottle as +cleanly as you can--that is, without touching the sides--and press it +down with the flat end of a stick if it is not level. Now cork it, and +put the bottle away in a cool place till required for use. + +This is, I think, the best way of charging the bottle; but there are two +other common methods that may, perhaps, be regarded as a little more +simple. One is this: put a few small lumps of the 'cyanide' into your +bottle, and then cover them with a stiff mixture of plaster of Paris and +water, and press down as before. The other plan is to cover the +'cyanide' with a few thicknesses of blotting paper, cut just a little +larger than the inside of the bottle. The first of these two methods is +fairly satisfactory, but I have always found that the charge, when made +in this way, has a tendency to become wet and pasty, in which condition +it will spoil the wings of the insects. The other is very objectionable, +especially for field work, for the blotting paper fails to keep its +place while you are on the chase. If the plaster is used, the mixing +must be done quickly and without hesitation, or the mixture will become +solid before you can press it into your bottle. + +We will not enter now into the _pros_ and _cons_ of the cyanide bottle, +but will consider the advantages and disadvantages of the various +methods of killing the insects after we have noticed a few more. + +The 'laurel box' has had many devoted advocates, although it does not +seem to be much in use now. It is a very good arrangement, however, but +is a little more troublesome than the cyanide bottle, as it requires +frequent replenishing. + +A very good laurel box may be prepared as follows. Get a small tin box +of cylindrical form, measuring about five inches by two, and cut a +circle of perforated zinc or wood just the size to fit it snugly as a +false bottom without any danger of falling out of its place. Now gather +some of the young leaves of the green laurel bush, and beat them almost +to a pulp with a mallet or hammer. Place this in your tin box, and press +down the perforated false bottom on it. The bruised laurel leaves give +off a very powerful odour, which stupefies butterflies immediately. + +[Illustration: FIG. 44.--SECTION OF THE LAUREL BOX. + +_a_, space for insects; _b_, perforated partition; _c_, bruised laurel +leaves.] + +Of course the reader may be able to think of various other ways in which +the laurel box may be made. Any arrangement will do providing the vapour +can come to the insects without allowing the leaves to touch their +wings; and any ingenious youth could manufacture a more satisfactory +article than the one I have mentioned. My desire is, as far as possible, +to give instructions that may easily be carried out by anyone, even if +he has not the slightest mechanical skill, leaving the clever youth, +sometimes, the opportunity of displaying his own inventive power. But in +this case I will give a few suggestions concerning other ways in which a +laurel killer may be constructed. A firm and _fixed_ false bottom is a +decided advantage. This is easily managed by fixing a circular piece of +perforated zinc or 'tin' by means of a little solder; or even a wood +partition may be used, fixed with a few brads, driven into it from the +outside. With the fixed partition, however, you must have a lid at each +end of the box. This is easily managed if you get two tins of the same +size, knock out the bottom of one, and fit the lid of the other in its +place. + +I have heard of laurel boxes without any partition save a piece of rag +in which the bruised leaves are wrapped. The whole is _pressed_ into the +box so firmly that it is not likely to be displaced while you are on the +chase. I do not recommend this, for in addition to the chance of its +slipping there is a danger of the sap of the leaves exuding through the +rag and spoiling the insects' wings. But if the reader should prefer to +try this on account of its simplicity, it will probably occur to him +that a bottle may be used instead of a tin box. + +A well-made laurel box, with a fixed metal partition, is a piece of +apparatus strongly to be recommended to all young entomologists who +desire to test the relative value of the various poisons that are used +by the different experts; for with it any one of these substances can be +used. In the poison compartment you can place pieces of 'cyanide' +wrapped in blotting paper, or any kind of porous substance moistened +with liquid ammonia, chloroform, benzole, or any other volatile liquid +insecticide. All the above-named substances are declared to be 'the +best,' so they must all be worth the trial. + +'Cyanide' is valued on account of its lasting powers. A cyanide bottle +well charged will retain its efficiency throughout a whole season. I +always recharge two in the spring, one for active service in the field +and the other as a reserve force; and these kept in a cool place do good +execution throughout the year. If they should exhibit a slight failing, +a few minutes' warming before a fire will improve them; but for field +work it is better to recharge. At the same time see that the corks are +in good condition. + +Next to the 'cyanide,' the bruised laurel takes the first rank for +permanency; but you must not expect this to last many days. For a few +days' continuous work one charge will suffice, but if the laurel box has +not been in use for some time you must have a fresh supply. + +The liquid poisons, such as ammonia, chloroform, and benzole, are so +volatile that they are very powerful for a short time, but so much +vapour is lost each time the box is opened that it is absolutely +necessary to carry a bottle of the one you use into the field with you. +Also see that you have sufficient of the blotting paper or other +absorbent to prevent the liquid from leaking through the perforations of +the partition. + +If you choose ammonia--a substance that is not regarded as a poison, and +is therefore easily obtained from any chemist--always get the strongest, +and see that it is labelled 'Liq. Ammonia, S.G. .880' as a guarantee. A +small bottle such as you can conveniently carry in the waistcoat pocket +will contain sufficient for a day's work. Use only a few drops at a +time, but renew frequently. Although the ammonia corrodes cork, yet a +good cork is far preferable for the pocket to a glass stopper, for its +elasticity prevents it from losing its hold, and the liquid from +saturating your pocket and its surroundings; but a glass stopper is +certainly better for the stock solution kept at home. + +Most of the above remarks apply equally well to benzole and to +chloroform, but the latter is so powerful a poison that a very little is +required for a day's work, and consequently a very small bottle is more +convenient. The dealers in naturalist's appliances supply metal +'chloroform bottles' with screw stoppers and a small nozzle that will +allow the liquid to run out only in drops. This is a very good +arrangement, since it enables you to avoid the 'drop too much' which is +not only unnecessary and therefore wasteful, but saves you from +experiencing the disappointment of an empty bottle before your work is +half done. + +[Illustration: FIG. 45.--THE CHLOROFORM BOTTLE.] + +Some entomologists recommend the solid carbonate of ammonium instead of +liquid ammonia, but this is not so powerful. It must be remembered that +we have the butterflies to consider, as well as our own convenience, in +the selection of the poisons we use. It is the opinion of many +well-known entomologists that 'insects cannot feel pain,' and that we +are therefore at liberty to deal with them in any way we please. Still +it is as well to save all possible suffering, and be satisfied with no +killing box that is not practically instantaneous in its effects. + +Among other poisons used by entomologists I may mention sulphur fumes +and tobacco smoke. The former may be obtained by burning a little +sulphur or a sulphured lucifer match under the perforations of a killing +box of the pattern described, and the latter--well, every smoker knows +that. I should at once condemn the former method, at least for field +work, as troublesome and inconvenient; and as to the other, I have tried +the effect of a puff (and many puffs) of tobacco smoke on an imprisoned +insect, but was so dissatisfied with the result that I am not likely to +do so again. + +We have now considered a good many insecticides more or less suitable to +our purpose, but there still remains the unsolved problem as to which is +the best. Each one has its advantages. For _convenience_ nothing beats +the cyanide bottle. It is very speedy in its action, and the use of a +bottle is a little preferable to a metal box, for you can always satisfy +yourself as to its efficiency without opening it. Cyanide, chloroform, +benzole, and some others render the insects more or less brittle and +stiff, so that it is not so easy to 'set' them for the cabinet. Perhaps, +if you happen to have a supply of growing laurel close at hand, you +cannot do better than stick to the laurel box. The time taken in +bruising up a few leaves is inconsiderable, and the moisture given off +from them will keep your insects moist and supple, or will even 'relax' +them if they have become rigid. But try various plans for yourself, and +you will be able to settle a question which all the entomologists in the +world cannot answer for you--which method answers best in _your_ hands. + +The next item for our consideration is the 'collecting box.' This is +merely a box in which the butterflies are pinned as soon as they are +dead. Here, again, we shall note a few variations from which a selection +can be made according to the means or the ingenuity of the reader. For a +couple of shillings you can obtain a good zinc collecting box, lined +with cork, of oval form (a most convenient shape for the pocket), and +quite large enough for one day's captures; and half that modest sum will +purchase a wooden box, also lined with cork, adapted to the same +purpose. + +As with many other things, so with collecting boxes, the cheapest is +often the dearest in the end. You may feel inclined to save a shilling +by buying a wooden box, but you are sure to discard it after a little +practical experience for a metal one. We shall speak a little later on +concerning the advisability of 'setting' the butterflies as soon as +possible after capture; but this is not always practicable, especially +after a good day's catch. Now, if the insects are pinned in a wooden +box, they soon become dry and rigid, and consequently cannot be 'set' +till they have been put through the more or less tedious process of +'relaxing.' If you use a wooden collecting box you will often find, on a +hot and dry day, that all or nearly all your butterflies are rigid +before you arrive home; but a metal box will keep them moist and supple, +so that you can even put off the setting till the following day if you +are unable to do it immediately after your return. + +Another point worth considering is the best economy of space. If your +collecting box is only about one inch deep inside, you have room for +only one layer of pinned insects; but a box only a little deeper may be +lined with cork both at top and bottom, and thus be made to accommodate +double the number. The zinc boxes sold by the dealers are generally +lined with cork in this manner, and are, of course, deep enough for the +double layer of specimens; but the wooden boxes are sometimes lined on +the bottom only. After these few remarks you will at once see the +economy of expending the extra shilling on the former. + +Although the prices of collecting boxes are low, yet there are many who +would prefer making their own, and there is much to be said in favour of +this. A great deal of pleasure is to be derived from the construction of +your own apparatus, especially when that apparatus is afterwards to be +used in the pursuit of a delightful hobby. During the whole of the time +thus engaged, you are looking forward with the most pleasurable feelings +to the glorious treat before you, and every joint you make seems to +bring you nearer to the realisation of your joys. During the bleak +winter months there is no better employment for an entomologist who has +a little spare time than the preparation for the next outing. It is just +one of those artful schemes by which he seeks to get as much pleasure +out of life as it is capable of affording. How many there are who, for +the lack of a pleasant and instructive hobby, find their leisure hours +the most dismal of all, and who complain of the toil and wearisomeness +of their lot! The mournful thought with them is, 'Is life worth living?' +but who ever heard such an expression from the lips of an active +entomologist? + +But I must have done with moralising and proceed to business. The +question is--How shall we set to work about the construction of a +collecting box? If it is to be a wooden one, select or make a box of +such a size as to suit your pocket or satchel, and cover the bottom, and +lid too if the depth allows of it, with sheet cork or slices of good +wine corks, about one-eighth of an inch thick, fixed on with glue. + +The metal box is not quite so easy, but even here you may save yourself +much work by keeping your eyes open. Very neat little collecting boxes +can be made out of the flat metal boxes in which are sold certain +favourite brands of tobacco. Some of these are just the right depth, and +also of a very convenient size for the coat pocket. Beg one of these +boxes from a smoking friend, and if the lid is not held by a hinge (a +great advantage, by the way), you can easily solder on a brass one. + +All that remains now is the fixing of the cork. Buy a sheet of cork at a +naturalist's shop, this being a commodity always in stock, and cut out +two pieces just the size to cover the bottom and the lid. + +Gum and glue are not very satisfactory as fixing agents, for, as you +will presently learn, there are times when it will be necessary to keep +the box moist, and moisture softens both these substances. The cork must +be fixed by means of little strips of metal. Here are two ways of doing +this: + +First.--Cut a few little strips of sheet tin, each about two inches long +and one-eighth wide. Double and bend them as shown in fig. 46, and +solder them to the surfaces which the cork is to cover (fig. 47). As the +cork is pushed in its place, these little slips are allowed to force +themselves through slits in it made by means of a penknife, and then the +ends are bent over as shown in fig. 48. Two or three such fasteners will +be quite sufficient to hold down each sheet of cork. + +[Illustration: FIG. 46.] + +[Illustration: FIG. 47.] + +[Illustration: FIG. 48.] + +[Illustration: FIG. 49.] + +Second.--Put the sheets of cork in their places _first_, then make a few +little slits through both metal and cork with the point of a penknife, +and then bind the two together with a few ordinary paper fasteners. This +arrangement is shown in section in fig. 49. + +Just one point more concerning the metal collecting box. You will often +call moisture to your aid in keeping the butterflies flexible and soft. +This will have but little action on zinc, but will sooner or later cause +the 'tin' (really tinned iron) box to rust. Here, then, is a point in +favour of zinc, but still a home-made 'tin' collector will last a long +time if kept dry when not in use. + +As already hinted, there are times when it is desirable to take home +certain butterflies alive, either for a study of their movements or for +the purpose of securing eggs for breeding. To this end you must provide +yourself either with a number of 'chip boxes' with a few small holes +pricked in the cover, or with some metal boxes with perforations for the +admission of air. If the latter, you will have no difficulty in +securing a few 'tin' boxes of suitable size, but, as the surface of the +metal is very smooth, you should always introduce a few leaves or +something else that will provide a foothold for the inmates. + +The last item of the outfit is the pins. Ordinary draper's pins are +quite out of the question. They are far too thick and clumsy for the +collector's work. If you are not already acquainted with the +'entomological pins,' you had better ask a dealer to give you a sample +card. This will be very useful for reference until you become well +acquainted with the various lengths, thicknesses, numbers and prices. +The card will contain one of each kind, with price and number attached. + +If you fix a butterfly with the ordinary pin, you may find the latter +partly covered over with verdigris after a time. This bright green +substance is formed by the action of decomposing animal matter on the +copper of the pin, and gives a very unsightly appearance to the +specimen. To avoid this the entomological pins are either silvered, +blackened or gilded. The silvered pins tarnish after a time, but the two +other kinds keep their colour well, and are therefore better. The gilded +ones are rather expensive and unnecessary, and perhaps the black ones +are to be preferred to the silvered, although they are rather more +costly. + +Most dealers will supply you with a box of mixed pins, each box +containing about six different sizes. This is very convenient for those +who work in a rather small way; but if you intend to make entomology a +prolonged study you had better get an ounce or so of each of the more +useful sizes. + +Butterflies vary much in size, and Nos. 3 to 8 are the most useful sizes +of pins to fix them; No. 3 being for the largest, and 8 for the +smallest. + +Supposing all the foregoing requisites to be quite ready, still you are +really by no means prepared for all your work. The butterflies captured +should be set as soon as possible after your return, and everything +required for _this_ part of the work must be in perfect trim. Yet I +think it will be more convenient just now to confine our attention to +the subject of 'Catching Butterflies,' leaving all the indoor work to +form the substance of another chapter. Our next point, then, shall be +the consideration of seasons, times, and localities. + +The earliest of the butterflies make their appearance on the wing in +April, or, if the weather is mild, towards the end of March; and from +this time you can find employment up to the end of September or the +beginning of October--a period of about seven months. But it must not be +supposed that all parts of this long season are equally prolific, and +will yield equally valuable catches. Remember the short term of a +butterfly's life, and bear in mind that each one has its own regular +season in which to spend the winged state; you will then see that anyone +who wishes to 'work' as many species as possible must arrange his +outings in accordance with the insects' own times. + +Some butterflies are double-brooded, and the two broods may not come +forth at certain fixed times. Hence they seem to be on the wing almost +without cessation for several months together, and therefore need not +have a special day set apart for them. But others are more uniform in +their date of appearance, and die off at about the same time. To catch +such as these you must be careful to watch the weather, make allowance +for any severities that may tend to cause a delay, or an unusually high +temperature that may hasten their emergence, and then select a day in +which you may expect to find them fresh and unworn. A week too early, +and none are to be seen; a week too late, and nearly all you catch are +worn and worthless. + +A glance at our Calendar (Appendix II) will give you a few illustrations +in point. Thus you will observe that May is a month for the 'Whites,' +early 'Blues' and certain of the Fritillaries; July for most of the +Hairstreaks and Browns, and so on. Before you have been long collecting +you will have captured the very common species, and then you will find +that your butterfly hunts are very unproductive unless you make it a +point to try for certain species at the proper times. + +Time, however, is not the only thing to take into account when preparing +for a day with the butterflies. It is equally important that we should +carefully select our locality in accordance with the known haunts of the +various species. As long as you are simply working up the common kinds, +you may wander almost at random in waste places, flowery meadows, corn +fields, railway banks, &c.; but when you have secured a few specimens of +each of these, you must search out the favoured resorts of the more +local and the rarer species. For instance, wooded spots must be visited +if you are to take certain of the Fritillaries, oak woods for the Purple +Emperor and the Purple Hairstreak, fenny districts for the beautiful +Swallow-tail, and so forth. In some cases the butterflies are closely +restricted to certain isolated localities, to which you must travel if +determined to obtain them. + +There yet remains another important matter to consider, and that is the +kind of day you shall select for your outing. Butterflies are not only +strictly day-fliers, but most of them venture out only on bright days. +Always choose as hot a day as possible, with a very bright sun. If you +are to be out for a full day's collecting, manage to be on the hunting +ground at about ten o'clock in the morning. As a rule there are not many +out before this time, and some do not appear to stir till an hour later: +still there are a few 'early birds' among them, one of which--the Wall +Butterfly--I have seen on the wing before eight. + +If your season, your day, and your locality are all well chosen, you may +reckon on a good six hours' work. At about four the butterflies begin to +lag, and then drop into their hiding places, one by one, till only a few +of the late stragglers remain on the wing. + +So far I have furnished some general instructions that may be regarded +as preparatory to the start; but I will now give a few hints as to the +mode of procedure when the day for field work has come. + +First, see that you have secured _all_ your apparatus, and that it is in +perfect condition. What is more annoying than to find, after you have +travelled some miles to get to your hunting ground, that you have left +your screw ferrule at home, or that the soldering of your metal Y is +just giving way? If you are troubled with a short memory, it will be +advisable to make out a list of every requisite for your field work, and +keep this for reference on all field days. + +Here is a list of your equipment for a day with the butterflies. Net, +ferrule or Y, stick, collecting box (the cork of which should be damped +if the box is a metal one), a few 'chip boxes' for live insects, killing +apparatus, a good supply of pins of several sizes, a piece of string, +needle and cotton, and your penknife. + +You observe in this list one or two items not previously mentioned, +since they hardly come under the category of apparatus, but a moment's +thought will convince you of their usefulness, especially in the case of +a breakdown. If your net catches in a thorn--a very common +occurrence--and a big rent is made, the needle and cotton will save you +a deal of agony, and perhaps loss of temper. If your stick breaks under +your exertions, the knife or the string may prove a most valuable +companion. Your pins may be stuck in the cork of your collecting box, +certainly the most convenient spot for immediate use; but you may also +have a reserve store in a small pocket cushion, or arranged neatly on a +strip of flannel which can be rolled up in the waistcoat pocket. + +At last you are on the hunting ground, fully equipped but inexperienced, +and at first find yourself just a little awkward in the use of your new +gear. Your experience with the cap has been a very wide one, and you are +possibly an expert at knocking down 'Whites' in the streets and in your +neighbour's kitchen gardens. Now you have to wield the net, and coax +your captives into your killing bottle; hence a slight feeling of +incompetence at first. + +You soon get over this, however, and within five minutes you may be seen +furiously slashing away at all the poor butterflies that come within +range, common 'Whites' and dingy 'Browns' receiving as much attention at +your hands as any rare gem that may happen to cross your path. + +How different are the movements of an experienced collector! He walks +stealthily along the route he has chosen, apparently taking but little +notice of the majority of butterflies that approach and pass him. He has +already secured his 'series' of nearly all the species, and is carefully +on the watch for the gems that are required to complete his cabinet. His +actions are slow and deliberate rather than rash; and he trusts more to +his eyes than his legs. + +The beginner may take to his field work quite to his own satisfaction, +and may travel homeward with a feeling of great pride over his first +day's catch; but yet there are a few points in which a little advice may +not be quite out of place, particularly so with regard to the management +of the net, and the killing and pinning of the insects. + +Most of the butterflies may be caught on the wing, and it is far better +to net them in the air than to sweep them off the herbage and flowers. +If these are rather low, you should strike the net smartly _upwards_ +from below them, but of course this movement is impossible with insects +that happen to be almost above your reach. If a butterfly is busily +engaged in searching out its sweet food, flying from flower to flower, +don't think of giving chase, but follow it up stealthily, and you will +sooner or later get an opportunity of striking at it while in the air. +Sometimes, however, you will see a powerful flier making a straight dash +across your field, taking no notice whatever of the fragrant blossoms, +but evidently engaged on some important errand. If such happens to be a +species you require, then you must run for it, but you will probably be +satisfied with only a few chases of this kind, particularly if the sun +is very hot, and the ground diversified with clumps of furze, heather, +'molehills,' and ditches. + +There are times when your only plan of netting a butterfly is to sweep +it from a flower or leaf on which it has settled. If the vegetation is +very low, you have simply to bring the net down upon it, and then, +holding up the apex of the net with the other hand so as to give it room +to fly, you can inclose it by grasping the lower part of the net as soon +as the butterfly has fluttered upward. If the herbage is tall it is +advisable to strike either upward or sideways at the insect, starting it +from the leaf or flower on which it rests; for if you bring _down_ the +net you will have to inclose the whole or part of the plant on which the +butterfly has settled--a procedure that often ends in a torn net, or in +the insect becoming damaged through being rubbed against the plant. + +Whenever you capture a butterfly by a sweep of the net through the air, +you immediately turn the ring into a horizontal position, so that the +bag of the net closes itself as it falls over the edge. This gives you +an opportunity of examining the insect before you introduce your killing +bottle. This is a very necessary precaution, for you are generally +unable to judge of the condition of a butterfly while on the wing, and +in some cases you cannot even be certain of the species. If, then, you +were to call the killing bottle into requisition for every capture you +make, you would certainly find yourself taking the life of many an +insect that is of no use whatever to you. Always examine your specimens +at the moment they have been secured, at least as far as it is possible +to do so, by looking through the gauze; and let your examination be as +brief as possible, or some of the butterflies that were at first in +splendid condition will render themselves useless to you during their +struggles to get away. + +When satisfied that an insect is likely to be of value to you, keep it +in the apex of the net by grasping the bag beneath it with the left +hand, and then introduce the opened killing bottle with the other hand. +As a rule you will experience not the slightest difficulty in coaxing it +into its trap, and then you quickly cover the mouth of the killing +bottle with the gauze, then apply your left hand, using it as a +temporary stopper for a few seconds, and now, the insect having been +quieted, replace the cork. + +A good killing bottle is almost instantaneous in its action, not only +stupefying, but immediately killing the insects; and as soon as you are +sure that each specimen is quite dead, you may pin it in your collecting +box. + +You must be cautious, however, on the one hand, that you do not take it +out too soon. If you do you may find that it recovers from the mere +stupefying effect of the poison, even after it has been pinned, and when +you open your collecting box for the next butterfly, you are horrified +at the sight of the poor victim struggling to free itself. + +On the other hand, don't keep the insects in the killing bottle too +long. If you do you will soon have a number, one lying on another, and +all tumbled about together while you are on the chase. Of course, under +such circumstances you are sure to damage them more or less. + +Many collectors, although they may always use a killing bottle for +moths, never employ one for butterflies, but kill them by pinching the +thorax. It is well to know how to do this, for it sometimes turns out to +be a really quicker process than that we have just been considering; +and, more than this, you can resort to it should you break or lose your +bottle while in the field. It is done in this manner: Bring the two +opposite sides of the net together, closing them on the insect so that +it cannot flutter. If now the wings are brought together over the back, +all is right, but if not, give it just a little room to flutter till you +have the opportunity of closing the gauze upon it with the wings in the +desired position. Now pinch the thorax smartly between the finger and +the thumb, applying the pressure outside the net, but be careful not to +squeeze the abdomen. In a moment you will find the insect quite dead, +and not in the least damaged unless you performed the operation +clumsily. + +Now as to pinning. Hold the dead butterfly between the finger and thumb +of the left hand, and pass a pin of convenient size through the centre +of the thorax above, and push it through so that the point appears +centrally on the under surface. It is now ready for your collecting box. + +So you work on till the sun begins to get low, and the butterflies +become fewer and fewer, till only a few stragglers of common species are +to be seen. Still there are a few hours of daylight and perhaps even of +bright sunshine before you, and if you are not weary with the work done, +you may very profitably spend these hours in the collection and study of +the habits of moths. + + +_Catching Moths by Day_ + +The reason for choosing the sunny hours for butterfly collecting is +obvious, all these lovers of brightness being then actively on the wing; +and although many may be driven out of their hiding places by beating +the herbage with the handle of your net, or even be searched out as they +rest on stalks and leaves during dull days or at morning and evening +twilight, yet such methods are comparatively tedious and unproductive. + +Some moths also are lovers of sunshine, and while engaged in butterfly +hunting you will often meet with a moth flying briskly from flower to +flower and taking its fill of both sweetness and brightness. Again, as +you wade among flowery herbs in quest of butterflies you will certainly +disturb a number of moths, causing them to take a short flight in search +of a safer spot. Thus you will almost invariably find a few moths among +the contents of your collecting box even though you made no special +effort to seek them out. But we shall now see how we may set to work to +obtain a successful catch of moths at times when butterflies are not so +much in demand, or during the less brilliant hours of the day, when +butterflies are at rest. + +The apparatus required for this work need not differ in any important +respect from that recommended for butterflies. The same net is used, any +reliable killing bottle will do, and the pins and collecting box used +for butterflies are equally serviceable. But your mode of procedure is +very different. + +As you walk towards your proposed hunting ground you will do well to +examine the trunks of trees, old walls, and wooden fences. In this way +you will meet with moths fast asleep, which are consequently easily +taken. All you have to do is to hold the open killing bottle obliquely +just below the insect, and then push it gently downward with a small +twig or stalk. As a rule the moth will drop direct into the bottle and +make no attempt to fly away; but some are very light sleepers, ready to +take flight at the slightest disturbance; and when dealing with these +you must be careful to bring the mouth of the killing bottle so closely +round them that there is no room for flight except into the bottle +itself. It is well, however, not to take long at this kind of searching, +but to reserve as much as possible of your time for what you consider to +be a very favourable locality. + +Speaking generally, a good locality for butterflies is a favourable one +also for moths, and you will do well to give special attention to +well-grown hedges, especially those that surround clover fields; also +overgrown banks, the borders of woods, open spaces in woods, the trunks +of isolated trees, gravel pits, and old chalk quarries. + +Walk beside or among the undergrowth of woods, or among the tall herbage +of waste places, tapping the branches and twigs with the handle of your +net as you go. Then, if your locality is well selected, you will rouse +moths to flight at almost every stroke. Some of these will shoot upward +among the lofty branches and disappear quite beyond your reach; others +will fly rather low and somewhat heavily, giving you favourable +opportunities to try your skill with the net; others, again, will fly +only a yard or so, and alight on a neighbouring leaf, often remaining so +quiet that the killing bottle is easily made to inclose them. + +There are moths that show a decided preference for large trees. These +may be seen hovering about high branches during the evening twilight, +and sometimes even in sunshine. In many such cases the chance of a +capture seems hopeless, but occasionally one will descend so low that a +watchful collector is able to secure it by a sweep of the net. + +If at any time you are in a locality by day where you suspect the +presence of certain species of moths at rest among the upper branches of +trees, such branches should be beaten if possible to dislodge the +insects they may shelter. A long stick will often serve this purpose +well, and, failing this, a few stones thrown among the branches may +prove effectual. In the case of small and rather slender trees, a kick +against the trunk will set the whole in vibration sufficient to surprise +all the lodgers; and the same effect may be produced with larger trees +by giving each a good sound blow with a mallet or some other suitable +implement. + +This or any other plan of 'beating' for moths is much more conveniently +worked by two collectors together than by one alone; for one engaged in +beating the herbage cannot be at the same time fully on the alert with +the net. If two persons are together, one may take the lead, armed with +the beating stick only, while the other, only very slightly in the rear, +is always ready to strike. + +We have said that butterflies should always be killed in the field, but +this plan is not so universally adopted with moths. Many collectors +carry a large supply of pill boxes when going out for the latter and +then take as many as they possibly can by boxing them direct in these. +This method of 'pill-boxing' is very simple in the case of the lazy and +soundly sleeping moths. It is only necessary to hold the open box below +the insect, and then cause it to fall by pressing the lid down gently on +it from above. + +Many of the moths so caught will remain quiet in the boxes and can be +taken home alive without much fear of damage. All may then be killed at +the same time by packing all the pill boxes in some vessel of sufficient +accommodation, and shutting them in with a little chloroform, ammonia, +benzole, or other suitable poison. The vapour will soon find its way +through the pores of the pill boxes, but, in order to make its action +speedy, each one should have a few perforations in the lid. + +Whatever advantages this method may give to the collector who works at +night, when the process of pinning would be more or less tedious, there +is no necessity for its adoption during the day. The large number of +pill boxes required is certainly far more bulky than the single +collecting box that would accommodate all the day's captures; and +although most of the insects boxed alive may be none the worse for the +shaking they get, and may not damage themselves by fluttering in their +small prisons, yet there is often a little loss on this score. + +If you do adopt the pill-boxing method, be very careful that you do not +mix the occupied boxes with the empties; and unless you fix on some +definite plan for the prevention of such an occurrence, you will often +find yourself releasing a prisoner from a box you have just opened to +receive a new-comer. + +Suppose that you start with all your empties in your right pocket. Then +each one, as soon as it is tenanted, might be placed in the _left_, with +the name of the insect, or any particular concerning it you would wish +to note, pencilled on the lid. + +When examining the trunks of trees you will be continually meeting with +specimens of very small Moths--_Pyralides_, _Crambi_, _Tortrices_, and +_Tineæ_--and at first may find some difficulty in boxing or bottling +such small and delicate creatures. A grass stalk will enable you to tip +some of them into your killing bottle, but some are so snugly packed in +crevices of the bark that it is almost impossible to get them out +without damage, even with a thin and slender stalk. But a sudden puff of +wind from your mouth will often be sufficient to dislodge them and blow +them into your net, and from this they are easily transferred to a box +or bottle. + +These few hints will prove sufficient to start you on moth-hunting +expeditions during the daytime, and will enable you to make good use of +the dull days and cloudy hours when the butterflies are quiet; but we +must now turn our attention to the night work of the entomologist, and +see how we may attract and catch moths during their hours of work and +play. + + +_Searching for Moths at Night._ + +It is a well-known fact that the night-flying moths are attracted by +lights, a characteristic of these insects that it is difficult to +explain. Their love of darkness is in many instances so decided that +they absolutely refuse to take flight while the fading light of day +still lingers on the horizon, and even display a great aversion to the +rays of the moon; and yet these very same species will often rush madly +into the fierce glare of a naked artificial light, or fly with an energy +almost amounting to fury against the glass of a street lamp or lighted +window. + +Puzzling as this peculiar tendency is, we can profitably turn it to our +own account by making it a means of luring a number of moths into our +presence. + +The simplest way of putting this mode of capture into effect is to post +yourself at your open window, with net and cyanide bottle at hand, while +the brightest light you can command casts its rays as far and as wide as +possible into darkness outside. If you use an oil lamp for the purpose, +let it stand just inside the window frame, or, if a jointed gas bracket +happens to be situated beside the window, bend it round so that the rays +may pass over a wide area outside. + +Two such lights are sometimes a very decided advantage--one quite +outside the window to attract the moths from all possible points, and +then another near the middle of the room to invite them inside. Whether +you use either one or two lights, always see that it or they are so +surrounded by a screen that the moths cannot by any possibility rush +into the flame. There is nothing better for this purpose than a covering +of light gauze, for this is not only a barrier for the prevention of the +suicidal tendencies of the insects, but it also gives a good foothold to +those who would like to rest and enjoy the luminous feast. + +You will soon begin to learn that moths, like ourselves, exhibit great +differences in their ways of enjoying their festal moments. Some will +satisfy themselves by flying _near_ the light in almost a straight +course, hardly slackening their speed as they pass; or will, perhaps, +make a hurried curve round the light and then pass on at once about +other business. To catch these you must be always on the alert, with net +in hand, ready to make a dash at the right moment. But many will make +straight for the flame, and then, finding a barrier in the form of gauze +or glass, will either flutter round and round as if dissatisfied with +your attempt to save them from an untimely end, or else settle quietly +on the screen to enjoy the brightness for a long period. The flutterers +are usually easily covered by a glass or the open cyanide bottle, and as +for those that settle down quietly, you can take them at your leisure. + +It will not do for a collector to depend solely on this method of +obtaining moths, but at times when either his duties or the bad weather +keeps him at home it affords him a means of capturing a few specimens +that otherwise would have been missed. He may be even so busily engaged +in other matters that he cannot afford the time to stand and watch with +net in hand, but the insects that fly into his room and dance round the +gas jet or inquisitively examine the white surface of the ceiling are +easily netted or boxed without much loss of time. + +The chances of success at this kind of work will vary considerably with +the aspect, the season, and the weather. If your window opens on a large +flower or fruit garden, on a patch of wooded country with plenty of +underwood, a piece of waste ground overgrown with rank vegetation, or a +stretch of heath or moor, then you may expect a very large number of +visitors; but if you are situated on a level and barren country, or in +the dense atmosphere of a thickly populated district, you must not +reckon on many intruders. + +As regards the season, this is more extended than that of the +butterflies. A few species of moths may give you a call during the bleak +nights of October and November, and also during the somewhat less dismal +nights of February and March; but from April to September you may rely +on a goodly number of captures. Of course you will not expect many of +the 'rarities' and 'gems' to find you out; these are to be searched for +in the open field in the manner to be presently described; but your +lights will attract a large number of the commoner species of _Geometræ_ +and _Noctuæ_, the former _chiefly_ during the early summer, and the +latter more or less throughout the season. + +A little experience will show you that the atmospheric conditions form a +very important consideration. The dark and warm nights are the most +productive. Very little luck is to be anticipated when the full moon is +throwing down her silvery rays from a clear sky; nor will you see many +while a cold east or north-east wind is blowing. Under these conditions +many moths prefer to keep in the sheltered nooks where they slept away +the sunny hours of the day. They love a warm and moist air such as calls +forth the odours of the fragrant blossoms that provide their sweets, and +show no dislike to a fine drizzling rain that you yourself would prefer +to avoid. A pelting shower will generally keep them under cover, but +they delight in the fresh and moist air that immediately succeeds the +passing storm. + +[Illustration: FIG. 50.--FRAME OF NET FOR COLLECTING INSECTS ON LAMPS +AND WINDOWS.] + +If you reside on the outskirts of a town an occasional tour of +inspection of street lamps may add a few specimens to your collection, +and some entomologists attach so much importance to the value of these +luminaries that they provide themselves with a special net for the +removal of moths from the glass and rails (fig. 50). The straight side +marked _a_ is applied to the panes of glass when flutterers or settlers +are to be taken, and the bend on the opposite side is to secure those +that rest on the rail. Such a frame is easily made by bending a piece of +stout wire to the required shape, and then soldering it to a ferrule to +receive a long stick. The net itself should not be deep. + +Many different forms of traps are now made for catching moths, and these +are deservedly coming rapidly into favour. They are generally +constructed on a 'catch-'em-alive-oh' principle, and have the advantage +that, after having been set, they may be left alone all night without +any watching, and give an ambitious collector the opportunity of taking +insects in his garden and searching in the open field both at the same +time. + +One of these traps may be constructed as follows at the cost of only a +few pence over the price of a small paraffin lamp. Put together a square +box, the sides about two feet and the front open, or procure a suitable +one from your grocer. Place a paraffin lamp with a bright tin reflector +at the back of this, and make a hole in the top just over the chimney to +allow the heated air to pass out freely. Three sheets of glass are now +to be placed as shown in the sketch (fig. 51), one upright piece +completely shutting off the lamp, and two others placed obliquely with a +space between them just large enough to allow admission. These must be +exactly the width of the box, and should not be permanently fixed, but +simply resting on small wooden supports nailed on to the sides. When +required for use, it is only necessary to light up the lamp, strew some +dead leaves on the bottom of the box, and put the sheets in their +places. It will be seen at once that the angles at which they are placed +will direct all light-seekers into the lower compartment, whence they +are not at all likely to find their way out again; and after vain +endeavours to reach the light they finally settle down on the sides of +the box or seek shelter among the dead leaves. + +[Illustration: FIG. 51.--A TRAP FOR CATCHING MOTHS.] + +Occasionally it happens that an entomologist is lucky enough to claim +the friendship of a person who, from the nature of his calling, is +peculiarly well qualified to render him great assistance. Thus a +friendly lamplighter, expert and patient in the use of the cyanide +bottle or pill box, is capable of giving valuable aid at times; and the +keeper of a lighthouse has it in his power to capture many a gem that is +seldom seen on the wing; but, although much may be done by means of +these and other stationary lights, this kind of work does not compare +favourably with the night rambles of a naturalist in the very haunts of +the objects of his search. + +For such out-door work in search of moths a good lantern is essential. +An ordinary 'bull's-eye' is almost useless, for, although it +concentrates a good light on certain objects, the narrow range of its +rays constitutes a strong objection to its use for entomological work. +For this purpose it is necessary that the rays of light not only pass in +front of you, but also shoot off right and left to warn you of the +approach of a moth before it is too late to wield the net. This wide +range may be obtained by means of three flat glass sides, or, better +still, by a bent plate glass front. + +In addition to this you must go out provided with your net, killing +bottle, and a number of pill boxes. Choose your night according to the +hints already given, and if you are on the look-out for any particular +species, be careful that the date of your outing is well timed, making +any necessary allowances for the forwardness or backwardness of the +season, for a moth that is generally due on a certain _average_ time of +the year may appear some weeks sooner if the preceding weeks have been +unusually warm, or its emergence may be delayed considerably by the +prevalence of cold east winds or a late frost. + +Make up your mind as to the field of your operations before you start, +and if possible choose a route that will carry you through a variety of +situations, so that you may pass the favourite haunts of a number of +different species. Clearings in woods with an abundant undergrowth, +waste places with plenty of tall and rank vegetation, overgrown railway +banks, clover fields, the flowery borders of corn fields, plantations in +parks, heaths and moors, sheltered and overgrown hollows such as chalk +pits and old disused quarries, reed and marsh land, all these are good +localities, each one inhabited by its own peculiar species, and if your +route runs through a fair variety of such places you may, other things +being equally favourable, depend on a good catch. + +See that your time also is well chosen. Of course you cannot say exactly +what the night will be till it actually comes, and, as you have to start +off before it is dark, you must consider the probabilities of the future +from the present condition of the air. Let it be a night when a bright +moon is not due, and if it follow a warm and moist day with a south or +south-west wind, or if drizzly, so much the better; but let your feet be +shod with boots that will permit you to wade through moist herbage +without danger, and take a waterproof if necessary. + +It is always advisable to be on your hunting ground before twilight sets +in, as a number of moths venture out before the sun has disappeared; and +then you can work on till midnight if you feel inclined, or even extend +your labours till the early hours of the morning. + +Before dusk you will meet with many of the little _Tortrices_ (page 298) +in sheltered spots, and a little later the _Geometræ_ and Hawks will be +on the wing. Thus, before dark, you may make good use of your net, +dealing with your captures just in the same way as recommended in the +case of butterflies. + +After a time, however, the lantern will have to be brought to your +assistance in making known the whereabouts of the later species, +consisting chiefly of the _Noctuæ_, many of which do not make their +appearance till it is quite dark. If now you carry your lantern in your +left hand, your work will be rendered somewhat difficult and tedious, +for, although one hand is sufficient to manage the net properly, you are +compelled to rest your light on the ground every time you make a +capture, as it is impossible to box your specimens unless both hands are +quite free. This difficulty is easily overcome by suspending the lantern +by means of a string or strap placed round your neck, allowing it to +hang on your chest; and a further advantage is gained by having a second +strap round your chest to prevent it from swaying about with every +movement of your body. This arrangement gives you both hands perfectly +free during the whole time, and also prevents the necessity of +continually bringing yourself into a stooping or kneeling posture while +you are examining or boxing the specimens you have netted. + +There are now two courses open to you. Either you can kill and pin the +moths as you catch them, fixing each one securely in the collecting box, +or you may simply shut each one in a separate pill box and leave the +remainder of the work to be done at home. If the ordinary collecting box +only is used, a little of your time is necessarily occupied in pinning +and transferring, and if many insects are about such an occupation may +appear to you to be a waste of valuable time. But this is not all. Often +and often will you find that while thus engaged a splendid moth will +come and flutter round your light; and, before you have time to drop +your collecting box and pick up the net, the fine creature you would +have prized has darted off again. This certainly seems to speak in +favour of the pill-boxing method, but it must be remembered that a few +of the moths will continue to flutter after they have been boxed, so +that when you arrive home they are more or less damaged, a large number +of the scales that once adorned the wings now lying on the sides and +bottom of the boxes. Perhaps the best plan is to take both the +collecting box and also a quantity of pill boxes, and a little +experience will soon show you which is the better accommodation for +certain kinds. + +Particular attention must be paid to flowers, some of which are very +attractive to the _Noctuæ_ especially. Sallow blossom in spring and ivy +bloom in autumn should be carefully and frequently watched, and at +other times the blossoms of heather, ragwort, bramble, clover, and +various other flowers must be searched. + +As you cast the rays of the lantern on the feasting moths some will +prove themselves very wary, and dart away at your approach; but others +will take but little notice of your advance, and will continue to suck +the sweet nectar, their eyes glaring like living sparks. + +As a rule the _Noctuæ_ thus engaged are easily pill-boxed or caught +direct in the cyanide bottle; but a few of the more restless species are +to be made sure of only by a sweep of the net. Some will feign death as +soon as disturbed, and allow themselves to drop among the foliage, where +further search is generally fruitless. + +Another common difficulty arises from the inconvenient height of many of +the attractive blossoms--often so great that it is impossible to reach +them with the net, and very difficult to direct the rays of your lantern +on them. This is particularly the case with sallow and ivy, the flowers +of which are two rich sources of supply to the entomologist. + +[Illustration: FIG. 52.] + +[Illustration: FIG. 53.--NET AND LANTERN FOR TAKING MOTHS FROM HIGH +BLOSSOMS.] + +Those who intend giving special attention to these blossoms should be +provided with some form of apparatus that will enable them to extend +their operations as high as possible. Perhaps the most effective +arrangement is the well-known combination here figured. It consists of a +long and stout stick, at the top of which is a tubular joint (fig. 52) +that might be termed a T-piece were it not that the smaller part does +not stand out at right angles to the other. In this is fixed, in a +straight line with the stick, a short rod on which hangs a lantern--an +ordinary bull's-eye answers well here; and in the smaller tube is +another short rod carrying a shallow basin-shaped net, and of such a +length that the net is just in advance of the lantern. + +At first sight this arrangement will strike you as being very +unsatisfactory, there being no kind of trap to prevent the escape of the +insects. But it must be remembered that moths are more or less addicted +to habits of intemperance--that they will hold on to the supply of the +sweet fluid they enjoy till they are ready to drop with intoxication. +This being the case, some will fall into your net as soon as they are +startled by the sudden and near approach of the glare of your lamp, and +others are easily _made_ to fall therein by gently tapping the +flower-bearing stems from below with the edge of the ring. + +Having become acquainted with this very sad propensity, which thus +brings ruin to so many unfortunate moths, can we not yet further turn +their evil doings to our own profit in our endeavours to become +acquainted with their structure and history? Most certainly we can. All +we have to do is to distribute in their haunts a bountiful supply of +some artificial intoxicant such as they love, and then lie in wait for +the victims that fall a prey to our snare. This process is known to +entomologists as 'sugaring,' and is a splendid means of securing an +abundance of species, often including some rare ones that are scarcely +to be obtained by any other plan. Let us now inquire into the _modus +operandi_ of this interesting operation. + +The first thing to do is to prepare the luring sweetmeat. Supply +yourself with a quantity of strong, dark treacle, and also some dark +brown sugar; always remembering, in the selection of these viands, that +odour rather than purity is to be the guide. The best kinds of sugar are +those very dark and moist brands imported in a raw state from the West +Indies, nothing being better than that known as 'Jamaica Foots.' + +Mix about equal quantities of these with a little stale beer, and boil +and stir till all the sugar is dissolved. The consistency of the mixture +should be such that it will work well with a brush when used as a +paint--not too thick, nor so thin that it is easily absorbed by the +substance on which it is 'painted,' nor must it be in such a fluid +condition that it easily runs. + +When satisfied on these points, transfer the mixture to a tin canister, +see it properly covered, and set it aside as your 'stock' from which you +can draw supplies as required. Now secure an ordinary painter's brush of +convenient size, and a number of strips of linen or other rag, each one +of which is fastened to a hook formed of bent wire. These items, +together with the usual lantern, collecting box, pill boxes, and killing +bottle, complete your outfit for the sugaring expedition. + +When the selected time for operations has arrived, take sufficient +'sugar' for your night's work, mix it well with sufficient strong rum to +give it a very decided odour, and start off at dusk with this and the +other requisites just mentioned. + +The night chosen should be warm and calm, with a rather damp atmosphere, +and no moon preferred. Let your locality be a well-wooded one; +abounding, if possible, with giant oaks and other trees, and containing +open spaces with plenty of underwood and rank herbage. Such localities +are to be met with at their best in forest lands, and if you would do +wonders at sugaring you cannot do better than arrange for spending your +holidays in such a spot as the New Forest, taking with you sufficient +'sugar' for several nights' work. + +Having reached a likely spot of no very great extent, you prepare for +real work. Light up the lamp, and get out your sugaring tin and brush +ready for action. Take your course along some definite track that you +are sure to remember, painting vertical strips of sugar, about a foot +long, on the trunks of trees or on palings, and hanging strips of rag +that have just been steeped in the sugar on the branches of small trees +and shrubs where you do not find good surfaces for the brush. + +After satisfying yourself concerning the amount of sugar distributed, +retrace your steps, examining every patch of sugar as you go. It will +not be long before signs of life appear. Earwigs, spiders, centipedes +and slugs will soon search out the luscious feast, but unless the time +and the locality are ill chosen, the lantern will soon reveal a goodly +number of moths, with eyes glaring like little balls of fire, greedily +devouring the bounteous repast. These will consist chiefly of _Noctuæ_, +but _Sphinges_, _Geometræ_ and numerous small species also join the +company. + +Some will exhibit a restless disposition, either darting off before you +make a close approach, or keeping their wings in rapid vibration as if +to be fully prepared for a hasty retreat when occasion demands. These +must receive your attention first; and, having secured them, proceed to +box as many as you require of the more lazy and gluttonous species. + +As a rule, moths thus engaged are easily pill-boxed, but the livelier +ones will not submit to such treatment without attempting to escape. The +best way to secure these is either to cover them with the opened cyanide +bottle (or its substitute), and replace the cork as soon as a favourable +opportunity occurs; or to perform the same feat with a glass-bottomed +pill box. + +The advantage of the latter over the ordinary boxes will be seen at +once. After the insect is covered, its movements can be watched, and so +a favourable opportunity can be seized for snapping on the lid. + +As already stated, some moths feign death when in danger, allowing +themselves to fall in places where they are often quite safe from +capture. Others allow themselves to fall simply because they have so +gorged themselves with the intoxicating sweet that they can no longer +maintain their hold. Both these classes of sugar seekers may easily be +secured by means of a net commonly known as the 'sugaring net.' + +[Illustration: FIG. 54.--FRAME FOR THE SUGARING NET.] + +This implement is so simple in its construction that anyone can easily +make his own. The frame may consist of two straight wires or canes fixed +in a metal Y, and the other ends joined by a piece of strong string or +catgut as shown in fig. 54. The net itself need not be deep. As soon as +you reach a tree where moths are feeding on the sugar, press the string +of the net against the bark just below them. The string at once assumes +the form of the trunk so well that you may be sure of every insect that +falls while you are boxing. + +For this work both hands must be free, and this is easily managed in +spite of the number of appliances called into service. The lantern is +slung round your neck and secured by a strap round the chest. The +'sugaring net' has a very short stick, and just while you are engaged in +boxing specimens, it may be gently held against the trunk by a slight +pressure of the body. But such precautions as these are necessary only +when the night worker is out alone. There are many circumstances, +however, that render the work of two or more in company much more +enjoyable than that of a single-handed entomologist. The labours are +considerably expedited where a division enables each one of the night +ramblers to take a particular portion of the work; and if there is such +a person as a nervous entomologist, that individual should on no account +go a sugaring in lonely spots on dark nights. Every rustling leaf gives +such a one a start; all footsteps are those of approaching disturbers of +the peace; and when at last the invisible landowner or his keeper, +attracted by the mysterious movements of the lamp, greets him with his +gruff 'What's your business here?' then for the moment he forgets his +enchanting hobby and wishes he were safely at home. + +It is certainly advisable to take a friend, whether an entomologist or +not, on such expeditions; and if you intend working on private grounds, +always make previous arrangements with the property owner, that you may +fear no foes and dread no surprises; for a sugarer is far more sure of +success in his work if he keeps a cool head and has nothing to think +about for the time being but his moths and his boxes. + +A few hours at this interesting employment pass away very rapidly, and +when midnight arrives there is often no great desire to leave off, +especially when it is known that some species of moths are not very busy +till very late at night. Still it is not advisable to surfeit oneself +with even the sweets of life. Perhaps it is better as a rule to work the +early species only on one night, and reserve another for the later ones. +The searchings are then always carried on with vigour throughout, and +the labours that are thus never made laborious ever retain their +attractiveness in the future. + +It has often been observed that, when sugaring has been carried on for a +few successive nights in the same locality, the success is greater each +night than on the one preceding it. Hence it is a common practice to +work a chosen 'run' for two, three, or more nights in succession; and +some collectors even go so far as to lay on the bait for a night or two +previous to starting work. For the same reason it is often advisable to +continue the use of a fairly productive beat rather than to wander in +search of a new one. + +In the neighbourhood of large towns one may often meet with patches of +sugared bark that mark the course and extent of a brother entomologist's +beat, and such are valuable to an inexperienced amateur in that they +give him some idea of the nature of the localities that are chosen by +more expert collectors. But it must be remembered that each entomologist +has a moral right to a run he has baited, and that it is considered +ungentlemanly, if not unjust, to take insects from sugar laid by +another. I have sometimes seen cards, bearing the names of the +collectors and the date of working, tacked on to baited trees and +fences, thus establishing their temporary exclusive rights to the use of +their runs. Such precautions are not necessary in large tracts of forest +land, where the choice of runs is practically unlimited. + +There are two other modes of capture available to the moth +collector--the use of decoy females, and the employment of 'sugar +traps'--and both these may be used on the sugaring run, or at other +times either in the woods or in your own garden. + +The wonderful acuteness of the sense by which the males of certain +species are enabled to seek out the females has already been alluded to, +and the possession of a suitable decoy will often bring you a number of +beautiful admirers without the least trouble, except that taken in +securing the decoy and preparing her temporary abode. It is absolutely +necessary that the female moth be one that has recently emerged, and +consequently you had better secure her in one of her earlier stages, +either by previous rearing or by collecting the pupæ. + +A little cage composed of a framework of wire covered with gauze must +now be made. Perhaps the simplest pattern is that illustrated. Here the +gauze is attached to two wire rings, only a few inches in diameter, and +suspended by a string. Such a cage answers every purpose in the field, +and has the advantage of folding into an exceedingly small space when +not in use. It may be suspended in your garden or taken into the field +whenever you have a suitable decoy at your disposal. + +[Illustration: FIG. 55.--CAGE FOR DECOY FEMALES.] + +[Illustration: FIG. 56.--A SUGAR TRAP.] + +The sugar trap may be of much the same pattern as that in which a light +is used, but if intended for field work it should be of a convenient +size for portability. A lighter and far more convenient form may be +constructed as follows: + +Procure a large cylindrical tin box, and cut a circular piece of +perforated zinc just small enough to drop into it. Then make two wire +rings, one a _little larger_ than the top of the tin, and the other only +about an inch in diameter. Next make a conical net of leno, open at both +ends, and of such a size that the two rings may form the frames of its +two extremities. When the trap is required for use, cut a circular +piece of flannel or other absorbent, steep it in sugar that has just +been flavoured with rum, and place it in the bottom of the tin. Then +place a few pebbles of equal size around the sides to support the zinc +partition, drop in the partition, and then allow the net to hang on the +rim as shown in the sketch. + +This arrangement will explain itself. The moths, attracted by the sweet +perfume, flutter about in the net till at last they find their way +through the small ring. Once in, they make further attempts to reach the +sugar; and, at last, finding all efforts fruitless, and, like Paddy at +the fair, not being able to discover the 'entrance out,' they finally +settle down in a disappointed mood awaiting your pleasure. + +Perhaps another word of explanation is necessary here. Why not allow the +poor creatures to reach the sugar that attracted them to the spot? The +reason is this. They sometimes gorge themselves to such an extent that +their bodies, dilated to the fullest capacity with syrup, are a bit +troublesome when the insects are placed in the cabinet. It is therefore +advisable to see that the zinc is so far above the sugar that the moths +are unable to reach the latter by thrusting their extended proboscides +through the perforations. A few dead leaves scattered on the zinc is +also a useful addition, since it affords shelter to such of the insects +as prefer it. + +This is a very useful trap to keep in one's garden throughout the +season. It may not attract large numbers, but it has the advantage that +it requires no watching. It is simply necessary to set it at dusk, and +remove the captives in the morning or at your leisure. + + + + +CHAPTER VII + +_COLLECTING OVA, LARVÆ, AND PUPÆ_ + + +We have already observed that insects should, as a rule, be set as soon +as possible after their capture; and it would therefore seem that this +is the proper place for instructions in this part of the work. But it so +happens that butterflies and moths are to be obtained by means other +than those already described, and we shall therefore consider these +previous to the study of the various processes connected with the +setting and preserving of our specimens. + +Were we to confine our attention to the capture of the perfect forms +only, our knowledge of the _Lepidoptera_ would be scanty indeed, for we +should then be ignorant of the earlier stages of the creatures' lives, +and have no opportunity of witnessing the wonderful transformations +through which they have to pass. + +Such an imperfect acquaintance with butterflies and moths will, I hope, +not satisfy the readers of these pages; so it is intended, in the next +two chapters, to give a little assistance to those who would like to +know how to set to work at the collection of their eggs and larvæ, how +to search for the pupæ, and how to rear the insects from the stage at +which they are acquired till they finally emerge in the perfect form. + +These portions of an entomologist's work certainly take up a great deal +of his time, and also require much patience and perseverance; but the +advantages derived cannot be over-estimated, for in addition to the +knowledge gained of the early stages of insect life, this kind of work +will enable him to place in his cabinet a number of gems he would +otherwise have not and probably know not. Occasionally a prize may be +obtained in the form of a cluster of eggs (_ova_) of a rare species, in +many instances the larvæ are to be obtained with comparative ease, while +the perfect insects of the same species are not often seen or not easily +captured, and many a rare pupa has been dug out of its hiding place +during a season when the entomologist had but little other work to +occupy his time. + +These and other similar subjects we shall now consider in turn. + + +_Collecting Ova_ + +The collection of ova may be carried on more or less throughout the +year. A number of moths are out in February, and even in January if the +weather is mild. These soon lay their eggs, which are hatched about the +time that the buds of the food plant are breaking. From this time till +late in the summer the ova of various species are being deposited, the +average period from laying to hatching being from two to three weeks. +Then, during the autumn, when the leaves of food plants are turning +brown and crisp, ova are still being laid, but these remain unchanged +till the new buds of the following spring are bursting. + +Of course if you intend searching for the ova of particular species you +must previously ascertain the favourite haunts of those species, become +acquainted with their food plants, and also with the season or seasons +during which the eggs are laid. But the few following hints will suffice +as general instructions for the search. + +In nearly all cases we must expect to find ova on the food plants of the +respective species, but at times, especially with certain moths, we may +come across them in the most unlikely spots. Thus, it sometimes happens +that a moth settles on a street lamp, and lays her eggs on the framework +round the glass, or even on the glass itself. The same thing may take +place on the sash or glass of a brightly lighted window. + +Such occurrences, however, we must regard as accidental and +comparatively rare, and therefore we confine our searchings for ova to +the food plants of the species we require. + +As a rule the under sides of the leaves will yield the most, but we have +already noticed (page 18) that some moths leave their eggs exposed on +the upper surface. Again, some larvæ feed on flowers and seeds and +fruit, and the eggs of such are deposited on these parts. Those insects +which feed on the leaves of shrubs and trees often lay their eggs on +trunks, branches and twigs. Sometimes these are laid singly, sometimes +in dense clusters; and it is not unusual to find them arranged in rings +or spirals with great regularity. When examining the trunks of trees for +ova it is necessary to look well into the crevices of the bark, for some +insects take particular care to lay them in deep sheltered chinks; but +others take no such precautions, and deposit them on exposed ridges or +plain surfaces where they are easily discovered. + +One difficulty of the ova collector lies in the fact that many insects +lay on the upper branches of large trees. Of course a search for these +is out of the question; but in places where the trees have been cut down +a few years previously, and where a consequent undergrowth has +developed, there are considerable chances of success with these species. +Young saplings of trees often yield well, especially in places where +tall trees of the same species are absent. It may be mentioned, too, +that some moths (page 294) actually lay their eggs beneath the surface +of water, depositing them on the under surfaces of floating pond weeds; +and others (page 298) even enter the nests of wasps and bees for the +same purpose. It is clear, then, from these few remarks, that the work +of an ambitious collector of insects' eggs is by no means a monotonous +task; for his employment takes him into the meadows and woods, leads him +to the banks of ponds, and even compels him to tear down banks and +hedges for the nests of _Hymenoptera_ at the risk of a sting or two. + +One of the most productive sources of eggs is undoubtedly the possession +of captured females. When you are out netting butterflies you often see +a female that is evidently engaged in her matronly duties. Instead of +seeking food from the various flowers in her path, she pays attention +only to the foliage, looking out a suitable leaf on which to deposit her +eggs. Should you meet with an insect thus engaged which you would like +to rear at home, or of which you would like to know the egg, secure it +in a perforated pill box with a leaf of the proper plant; and it will +often supply you with abundance of eggs for your purpose, in many cases +depositing them in the box before you arrive home. The eggs of numerous +species of moths are also to be easily obtained from captured females. + +Some insects do not seem inclined to deposit their eggs in captivity as +freely as when at large, and in order to induce them to do so we must, +as far as possible, put them in their natural conditions. Let them have +plenty of room, and supply them with fresh twigs of their food plants, +kept green by standing them in vessels of water. It is also advisable, +supposing you are not well acquainted with the dispositions of the +species you have, to keep a portion of the box well shaded from direct +sunlight, and allow another part to be as bright as possible; for some +species will not lay in a bright light, while others will not do so +without it. + +Again, while some deposit their eggs within a few hours of quitting the +pupa case, others do not lay for several days. With regard to the +latter, it is frequently necessary to feed them while in captivity, by +placing in the box a piece of rag or sponge that has been dipped in +honey or syrup. + +Each batch of ova should be carefully examined with a view to knowing +them by sight on a future occasion. A sketch should be made in your note +book, showing every detail that you can make out with the aid of a good +lens. Then observations concerning the season, colour of the eggs, the +situation in which deposited, arrangement, and any other useful +particulars, should be entered. + +In the next chapter some hints will be given concerning the management +of ova and the rearing of the larvæ from the time of hatching. + + +_Collecting Larvæ_ + +This occupation is generally far more productive to the entomologist +than searching for ova. The latter are very small, usually well +concealed, and to be detected only by a careful scrutinising use of the +eyes; but the superior size of the larvæ, the frequent bright colouring, +and the fact that they are easily beaten from their hold, render the +searchings of their hunters comparatively easy and fruitful. + +Before setting out on a larva-hunting expedition, there are a few +requisites to prepare. These include not only the implements for your +work in the field, but also the cages in which you intend to rear your +little captives. The latter are described a little later on under the +head 'Rearing Lepidoptera,' and the former we will now briefly +summarise. + +The outfit must consist of a quantity of suitable boxes, a stout hooked +stick, a strong net, and a white material to place under the herbage +while you are 'beating.' + +'Larva boxes' are usually made of zinc, and have little sliding doors in +the lids, so that the lids need not be removed while out of doors after +the fragment of the required food plant has been inserted. Such boxes +are not by any means essential. Small tin boxes will answer all purposes +nearly as well, providing a number of small holes be made in them for +the admission of air. Chip boxes are also fairly satisfactory, but these +also should be perforated. The best way to do this is to push a red-hot +iron wire through the chip, making about half a dozen small holes in +each box. This method will give you clean holes of a uniform size +without otherwise injuring the boxes. + +Metal boxes possess the advantage that they keep the food plants moist +for a long time, while chip boxes allow them to dry rather rapidly. Yet +there are some larvæ that do far better in the latter, since such a +quantity of moisture exudes through their skins that they soon become +uncomfortably wet if their apartment is not well ventilated. Under these +circumstances perhaps it is better to take a supply of both, so that +changes may be made as found necessary. + +One grave objection to chip boxes, however, is the weakness of the +material. They are easily crushed by pressure, and a bottom or a top +disc of wood often falls out; but this is easily overcome by gluing +narrow strips of calico round the top and bottom edges. Chip boxes +should always be treated in this way, and they will then last five or +six times as long. + +Your supply of boxes should always include one large one of metal in +which to bring home a supply of food for the larvæ. If you have a +botanist's vasculum, by all means take it, for nothing can serve this +purpose better. If not, any rather large square tin box will do, and +this may be carried in your satchel, or a couple of hooks may be +soldered to it so that a leather strap can be fixed for slinging it over +your shoulder. + +The net required is that commonly known as the 'sweep net.' It must be +very strong, for it has to submit to rather rough usage. The frame must +be made of thick wire; and the bag, which need not be more than a foot +deep, should be of strong calico or holland. + +Now with regard to the white material previously mentioned. This may be +a square of calico, hemmed round the edges. Nothing is more convenient +than this, as it occupies but little room in the pocket when not in use, +if neatly folded. The material need not be thick, but the larger it is +the better. Many prefer a white umbrella or an ordinary umbrella with a +white lining, but as this is only a matter of taste and convenience you +must decide for yourself as to which you will use. + +If your field of operations is only a little way from your head +quarters, and quantity of luggage therefore not a serious consideration, +you may provide yourself with a heavy mallet, loaded if necessary with a +pound or two of lead. This will prove very useful in shaking larvæ from +trees and large branches. Lastly, take a pencil and a note book or +writing paper for your observations in the field. + +Now for the choice of the season. Larvæ are to be found all the year +round. Early in the spring, as soon as the buds are bursting, some break +out of the eggs recently laid by the moths that appear in February and +March. Later on, during April and May, a host of both butterflies and +moths are busy arranging for their broods. Then, throughout the whole of +the summer, thousands of caterpillars of all sorts and sizes are to be +met with everywhere. And finally, during the bleak winter months, you +may amuse yourself by digging the hybernators out of their hiding places +where they rest themselves till the spring sun again calls them out to +refresh them with the young and tender leaves of a new year. Thus, +unless you are merely intending to search out certain species you happen +to require, there is not much difficulty in settling on the season. + +The day selected should be dry, for your work lies among the herbage of +banks, meadows, and woods, and nothing is more unpleasant than wading +through a wet and dense vegetation, or beating down on yourself a shower +of large drops from the branches of trees and shrubs. + +Having reached the hunting ground, the first thing to do is to look out +for _signs_ of the presence of larvæ rather than for the larvæ +themselves. Healthy vegetation with sound leaves must be passed by as +untenanted; but the presence of partly eaten foliage immediately arouses +suspicion. + +A little experience will soon enable you to distinguish between the +ravages of larvæ and of slugs, snails, wasps, &c. Some of the smaller +larvæ certainly eat out clean holes like those cut by _Hymenopterous_ +insects, but as a rule they bite away at the edges, leaving the midrib +and the larger veins standing out almost naked. + +By looking well into the edges of the eaten leaves, it is easy to see +whether the marauders have been recently at work. If they are dried up +and discoloured, it is not of much use to search; but if still green and +moist, you may feel almost sure that the hungry larvæ are not far off. + +In this case you will carefully turn over the leaves to examine the +under sides, and also the leaf stalks and branches or stems; but you +must be prepared for all kinds of protective mimicry. Little green +caterpillars will be seen lying on the midrib or veins, so straight and +so still that they are scarcely perceptible. Others are snugly tucked in +a depression of a leaf with the same result. Then we must also be +prepared for the artful little tricks of the larvæ of _Geometræ_ (p. +268), by which they imitate stalks and twigs so closely that a sharp eye +is necessary to discriminate between the two. + +While thus searching we may meet with the cast skin of a caterpillar. +This gives us fresh hopes, and so we continue our careful examination. +At last, on grasping a leaf in order to turn it over for inspection, we +feel something hairy or something soft and smooth. But lo! it is gone. +It is one of those numerous caterpillars that feign death and drop to +the ground on the slightest sign of danger. We search below for it, but +the density of the vegetation renders this hopeless, and we are just +about to start off in search of a more productive locality when we espy +a quantity of the excrement of larvæ lying on a little bare patch of +ground close by. This gives us a new idea. Here is another indication of +the presence of the creatures we require, one that we can put into +practice; and by-and-by we learn that in many cases this is really the +surest sign of their whereabouts. + +We look at these little pellets of excrement, and gain at once some idea +of the _size_ of the larvæ that produce them. Then we observe whether +they are fresh and moist, or dry and stale. If the latter, it is not of +much use to examine the leaves above; but if otherwise, there is little +doubt of our meeting with larvæ, as the present position they occupy is +so truly marked. The leaves just over them are carefully examined, +either by turning them over as before described, or, if the height of +the foliage admits of it, by placing our heads below and looking upward. + +If we find that the larvæ are some of those that endeavour to escape by +feigning death and allowing themselves to drop at the slightest +disturbance, the net is always kept beneath the leaves we are touching +in order to intercept them in their downward journey. + +Continuing the search, we meet with leaves that are rolled up and bound +with silk threads, and others that are drawn together and similarly +bound. These are carefully uncurled and pulled asunder with the result +that active little larvæ are exposed to view, or, it may be, pupæ are +discovered. In some cases flowers are drawn together in just the same +way, and an examination reveals one or more of the species that prefer +petals and other parts of flowers to the green leaves. + +Silken threads always arouse our suspicions. These may be seen lying on +the surfaces of leaves, and passing from one leaf to another, or they +may be hanging perpendicularly from the branches of trees above. In the +latter case a larva may be frequently seen on the lower extremity of the +fibre, swinging gently in the breeze, and, should we require it, we have +only to place the open box below for its reception. + +Hawthorn and other trees are sometimes seen almost devoid of leaves, +nearly every bit of green having been greedily devoured by a host of +small larvæ. In such cases we often meet with dense clusters of silk +fibres that may easily be mistaken for spiders' nests. But when we look +more closely into the structure we observe that we have discovered +instead nests of gregarious larvæ, such a large number being in each +little community that the deplorable appearance of the tree is at once +explained. + +A little farther on we meet with a sickly-looking plant in the midst of +a number of flourishing individuals of the same species, and stop to +make inquiries into the cause of this strange occurrence. Is it due to a +poorness of the soil? No, this cannot be the case; for intermingled with +its roots are those of its flourishing companions. We pluck a stunted +and half-shrivelled leaf and examine it. At first we do not notice the +cause of its peculiar condition; but, holding it up to the light, and +looking _through_ it, we see a number of little galleries that have been +eaten out of its internal soft substance, leaving the thin skin +(_epidermis_) almost entirely intact. But nothing more is to be seen. +Another leaf is examined in exactly the same way; and here we see the +little destroyer, lying motionless in its burrow till a gentle pressure +applied against it from outside causes it to wriggle along its narrow +passage. This is the larva of one of the little leaf miners mentioned +again on page 303. + +Reaching a little marshy spot we see a number of water-loving reeds, +most of them beautifully green and in a flourishing condition, but here +and there in their midst is a poor stunted specimen--another result of +the ravages of the larvæ of one or more moths. An examination of the +blades reveals nothing; but on splitting open the stalk we discover some +larvæ that have already devoured a quantity of the internal pith, and +thus endangered the life of the plant. On inspecting other similar reeds +we are at first puzzled as to how the larvæ could get inside the stems +without damaging the outer portion; but at last we see in each one a +little discoloured hole that was eaten out by the young caterpillar +just after its escape from the egg. Once within the reed, it found a +plentiful supply of food, and there grew at the expense of the plant +without doing any further external damage save by causing a stunted +growth. + +It may be that the stem eaters we have found are just about full grown. +If so we examine a number of the stems with a hope that we may find one +or two that are just about to change to the chrysalis state, or even a +pupa already formed. By this means we may secure one of the perfect +insects without the necessity of feeding larvæ at home. Such a +consideration becomes a most important one when it happens that the +required food plant is one that cannot be easily obtained. + +Close by the reeds is another water-loving plant in the form of an old +willow tree. This is always an attractive object to the entomologist, so +it comes in for a share of our inspection. On its leaves we may find +several species of the larvæ of _Lepidoptera_, including those of some +of our largest insects. But a strange feature catches our eyes as we +happen to glance at the bark of the tree. Here we see a few holes of +different sizes, about which are a number of little fragments of wood +that remind us of 'sawdust;' and, examining the ground below, we see +quite a little heap of this dust, looking just as if a carpenter had +been at work on the spot. + +This is not the effect of a saw, however; it is a sure sign of the +ravages of wood-eating larvæ (p. 224), whose powerful jaws gain them +admittance into the very hearts of trees, and the application of the +nose to one of the larger holes leaves no doubt of the presence of the +large and beautiful caterpillar of the Goat Moth (p. 224). + +If we require any of these wood-eaters, either for rearing or for +preservation, we must be prepared for a little rather heavy work. A +strong pocket knife is not sufficient, but with a good chisel the wood +can be gradually cut away, and the galleries traced, till at last we +come to the larvæ snugly resting in their burrows. + +It often happens that the tree thus tenanted is half decayed, and +consequently the work is rendered much easier. Also, while tearing away +the wood, we often meet with a number of cocoons that have been +constructed by the caterpillars for their winter quarters, or as a +resting place while undergoing their transformations. These are composed +of the wood dust bound together by strong silk fibres, and are often in +such a good state of preservation that they form useful illustrations +for the cabinet. + +As further aids to larvæ searching we may mention that many +species--chiefly of the _Noctuæ_--hide under the surface of the ground +or among dense and low herbage during the day, and come out to feed only +by night; that many others feed on roots, and are therefore seldom seen +above the surface of the soil; also that a good number burrow into +fruits, in the interior of which they spend the whole of their larval +stage. The best way to secure the latter is to examine the 'windfalls' +that lie scattered on orchard lands, for it is a well-known fact that +the fruits that are infested with larvæ generally fall earlier than +others--a result that must be attributed to the damaging work of the +larvæ themselves. + +All the larvæ collected should be carefully boxed at once, a separate +compartment being used for each species, and a few fragments of the food +plant being introduced in each case. It is also a good plan to have each +box previously lined with moss as a further addition to the comfort of +the captives. Without such a precaution some of the more delicate +species are liable to injury during their transmission from field to +home. + +Hitherto we have obtained our larvæ by _searching_ only, but there are +times and occasions when our boxes may be far more rapidly filled by +methods that are not such a tax on our time and patience. Suppose, for +instance, that we reach a bush, the mutilated leaves of which seem to +show that larvæ are present on its branches. We spread our white cloth +or open out the white-lined umbrella just under a selected branch, and +then tap that branch very smartly with our stick. + +Down comes a host of living creatures! Spiders, larvæ, beetles, aphides, +earwigs, and what not, struggling and running about on our white fabric +in all directions, and all mingled with bits of stick, leaves, and +fragments of all kinds. We leave the cloth or the umbrella, as the case +may be, quite still for a few seconds to allow all the living creatures +to get a good foothold, and then, raising it into a vertical position, +allow all the rubbish to drop off. + +We can now put the cloth down again, and select as many of the larvæ as +we require, giving our first attention to the nimble runners and loopers +that are already near the edge and just on the point of making their +escape. This productive method of larva hunting is known as 'beating,' +and is particularly applicable to tall herbs and the lower branches of +trees and shrubs. + +The same principle may be employed in the case of branches that are +quite out of the reach of the stick, but the blows are here applied to +the trunk, a mallet or some other rather heavy implement taking the +place of the stick. + +Another splendid method of securing larvæ where mere searching would be +tedious and unproductive, lies in the use of the sweep net described on +page 102. This implement comes into service in waste places that are +covered with rank vegetation, in clover and hayfields, and in all spots +covered with low herbs. + +Walking among the vegetation, the net is swept right and left before +you, and the contents examined at frequent intervals. It is advisable to +work the different species of herbs separately as far as possible, +otherwise there may be some difficulty in the determination of the food +plants of the mixed larvæ that the net will contain. If, however, this +plan is impracticable, you may save time by turning out all the +'sweepings' into one large box, leaving the sorting to be done at home +in leisure hours. + + +_Collecting Pupæ_ + +We have seen that ova and larvæ may be obtained in greater or less +abundance at all times of the year, so variable are the seasons of the +different butterflies and moths. The same remark applies equally well to +pupæ; but so many of the Lepidoptera spend the winter months in the +chrysalis state that this period may be regarded as the harvest time of +the pupa hunter. + +A large number of caterpillars undergo their change to the quiescent +state during the months of August and September, and, of course, remain +in this state until the warm days of the following spring or summer. And +as insects even in the pupal stage have a number of enemies and dangers +to contend with, it is advisable to start your search for them as soon +as possible after they have changed. + +If you set your mind on searching for particular species, you should +endeavour to ascertain the _usual_ time at which such species pupate; +make any necessary allowances for the forwardness or backwardness of the +season, and then allow a week or two for the change to be completed, for +insects should never be disturbed at times when their metamorphoses are +in progress. + +For general pupa hunting the best season is undoubtedly from the end of +August to the end of October, but there is no reason why the work should +not be carried on throughout the winter. If, however, you continue your +work so late, you must not expect nearly as much success as time +advances. You must remember that entomologists are not the only pupa +hunters. Many hungry birds are always on the look-out for insects, and +seem to enjoy them equally well in all their stages. Those that +hybernate on or under the ground are liable to fall a prey to moles and +beetles. In addition to these dangers, all pupæ are subject to the +effects of extreme cold, dampness, or floods. + +As regards the choice of a day, very little need be said. Any day that +is sufficiently genial for yourself will do for your work, except that +periods of hard frost render the ground too hard for digging--the most +profitable part of the pupa hunter's task. + +The apparatus required is extremely simple: A satchel or large pockets +full of small metal or chip boxes, a small garden trowel, and a strong +chisel. + +If metal boxes are used they should be perforated; in fact, nothing is +better than the ordinary larva boxes of the dealers. All the boxes, of +whatever kind, should be lined with moss previous to starting work. + +The trowel and chisel do not pack well with a number of small boxes, +therefore it is a good plan to fix them in a couple of leather sheaths +attached to your belt. In this position they are far more handy for use, +and the boxes are also in less danger of being crushed or damaged, as +they probably would be if in contact with hard and heavy tools. + +A note book is also a valuable addition to your outfit, as it enables +you to make memoranda concerning the trees and localities from which you +obtain your pupæ. + +The best localities for pupa hunting are clearings in woods, parks with +numerous large timber trees, and meadows in which large isolated trees +are scattered; and the best trees include willows, poplars, oaks, +beeches, birches, elms, and hawthorns. + +The best thing you can do on arriving at the selected hunting ground is +to make at once for isolated trees of large size, and work each one as +follows: + +First examine well the crevices of the bark, for many caterpillars +descend the tree to within a short distance of the ground, and then seek +out a snug little crevice in which to spend the winter, often protecting +themselves with silken cocoons, or constructing a neat little shelter of +gnawed fragments of the wood cemented together. + +If there is any loose bark, very carefully force it out with your +chisel, and examine both its inner surface and the wood from which it +was removed. The wood thus exposed may reveal openings of the galleries +of wood-eating larvæ, in which case, unless the material is too hard to +be broken up with the chisel, you may be able to trace out a few pupæ. +Where these exist, they are usually to be found very near the entrance, +sometimes even protruding slightly from the opening, for the larvæ +generally place themselves in this position of easy escape when about to +change. + +Next give your attention to the moss, if any, covering the lower portion +of the trunk. This affords a very favourite shelter to many species. +Tear it off very carefully, beginning at the top, and watch for loose +pupæ and cocoons as you do so. Then hold the clumps you have removed +over a patch of bare ground or over a spread handkerchief, and pull it +to pieces, in order that any pupæ it contains may fall out; also examine +the fragments carefully for others that may remain attached. + +This done, the surface of the ground must be examined. Remove all dead +leaves, and watch for pupæ that may be sheltered beneath them. If any +loose stones lie on the ground, turn them over. Search well into the +angles between the roots, and if there are any holes or hollows beneath +them or in the trunk itself, pull out all loose matter within, and +_feel_ gently above and around for cocoons. + +After all loose matter has been removed, there still remains the soil +for examination. If this is very hard and clayey, it is probably useless +to carry the search any farther; also if very wet you need not expect +much; but if comparatively dry and friable there are more hopes of +success. + +As a general rule the north and east sides of the trunk are drier than +those which are exposed to the heavy rains brought by the south and +south-west winds, and are consequently more favoured by larvæ that are +seeking a resting place for the winter. + +Most larvæ seek shelter in the angles between the roots of the trees on +which they fed, but a few species seem to prefer the edges rather than +the corners; and in cases where no such angles are formed at the +surface, you will do well to examine the earth and turf all round the +trunk; but it is generally useless to extend the search more than a few +inches from the tree. + +After having searched every available nook and corner as far as possible +without digging, thrust the trowel obliquely into the soil a few inches +from the tree, turn over the sod, and then examine the spot from which +it was removed. Now give your attention to the sod itself. If loose and +friable, break it up gently, keeping a sharp eye for falling pupæ, and +also for earthen cocoons that are easily mistaken for little lumps of +soil. + +If the soil is held together by roots, it must be pulled to pieces, and +the fragments shaken over a bare piece of ground where the fall of a +pupa or cocoon could be easily seen; and if you have removed a grassy +turf, it will be necessary to look between the bases of the blades as +well as among the roots. + +In this way you may search round tree after tree, wherever the soil is +of such a character as to allow of the admittance and shelter of larvæ. +But the variability of your success will be quite beyond your +comprehension. Sometimes you will sight a grand old oak with the most +favourable anticipations, and consider yourself quite certain of a good +find when you discover, on a nearer approach, the liberal coating of +moss that clothes its trunk and the dry sandy soil at its foot; and yet +the most careful search ends in nothing but disappointment. At other +times you try your luck at tree after tree without ever seeing a single +pupa or even a cast-off case, and then, when just on the point of +despairing, you search round another that is apparently much less +promising, and, to your great surprise and delight, a dozen or two are +turned out in a few minutes. Such an occurrence as this is not at all +uncommon, and cannot be satisfactorily explained, but we must take +things as they come and make the best of them, remembering that pupa +searching is one of the best of all entomological operations wherewith +to test one's perseverance and patience. + +It may be mentioned, in conclusion, that the pupæ of _Lepidoptera_ are +never to be found far below the surface of the soil. Generally they +exist, if buried at all, only an inch or two down, and very rarely at a +greater depth than four inches. + +In our next chapter we shall learn how to rear the perfect insects from +the earlier stages we have been considering. + + + + +CHAPTER VIII + +_REARING LEPIDOPTERA_ + + +_Management of Ova_ + +In the management of insects in all stages the strictest attention must +always be paid to one general rule on which the success of the work +almost entirely depends; and that is--keep every specimen as far as +possible under the same conditions as those in which you find it in +nature. + +Applying this principle to ova, we store them in airy and light places, +protected from the direct rays of the sun, and avoid handling and rough +treatment of any kind. It is also advisable in most cases to maintain a +slight amount of dampness corresponding with that of the open air at the +particular season of the year. + +They do not require much space, and it is certainly desirable not to +give much, otherwise the newly hatched larvæ, when their time arrives, +will actively wander all round their premises in search of food, and +give you no end of trouble in gathering them up. + +Chip boxes are, as a rule, very good and very convenient receptacles for +ova. After placing the eggs in these, cover them over with very fine +muslin, held in place by elastic bands; and label each as far as you can +with the name of the species contained, and other particulars worth +remembering. The boxes may then be put in front of a window facing +north, or in any situation within or out of doors where rain and sun +cannot reach them. A greenhouse is an admirable place in which to keep +them, the natural dampness of the atmosphere being apparently a +considerable assistance to the tiny larvæ just as they are striving to +escape from their shell. + +Whatever place is selected, it is absolutely necessary that the ova be +carefully watched, so that each brood may be supplied with the required +food plant within a few hours of quitting the shells. + +When ova are kept in a warm room, very great inconvenience and even loss +is sometimes caused by the appearance of larvæ before the necessary food +plant shows its buds. Yet, on the other hand, it is sometimes a great +gain to the entomologist to get certain broods off early in the season, +providing the food is at hand; for in this way he can not only get some +of his work over during a slack season, but also, if he desires it, +secure an additional brood; that is, one brood more than the usual +number. Thus, supposing a certain species he is rearing is naturally +double-brooded, he can, by judicious management, secure three successive +broods before the food plant casts its last leaves. + +This hastening of the natural events of insect life is known as +_forcing_, and merely consists in subjecting the species concerned to a +reasonable amount of artificial heat, such as that of a room in which a +fire is always kept, or of a hothouse. + +It is interesting at all times to note the dates on which eggs are laid +or collected, and the times at which the young larvæ appear. In addition +to this all changes that take place in the colours or forms of eggs +should be carefully observed; for such changes will assist you in +distinguishing between fertile and sterile ova, and also enable you to +judge approximately as to the date of the appearance of future broods. + + +_Rearing Larvæ_ + +The main point in connection with the rearing of larvæ is certainly the +selection and construction of the cages or their substitutes. For newly +hatched and all very small caterpillars a small bottle with a wide mouth +makes a very fair abode. Put a layer of sand or sifted soil in the +bottom, fix in this a small twig of the food plant or lay a few leaves +on the top, and then, after the larvæ have been introduced, cover the +top with a piece of muslin, held in place by an elastic band. + +The great drawback with this arrangement is the lack of any provision +for keeping the food moist and fresh, thus rendering a change necessary +at very frequent intervals; but this may be obviated by using damp sand +as a foundation for the little twig of food plant. With this +improvement, if you cover the top of the bottle with apiece of glass, a +saucer, or any impermeable substance, you may keep the twig fresh for +several days, generally until the disappearance of the last leaf calls +for a fresh supply; but it is very doubtful whether the damp atmosphere +resulting from this inclosure is not injurious to the larvæ. It +certainly does not seem to have much influence on some, but the +unhealthy conditions that result must be detrimental to the inmates. It +must also be remembered that many species require a _dry_ soil in which +to burrow when about to change. + +When the time comes for the change of food, great care must be taken not +to injure young and small larvæ. In many cases they need never be +touched, for if a fresh twig be placed beside the stale one, they will +readily find their way to it; and to facilitate this, and also to afford +a convenient foothold to those larvæ that accidentally fall from the +twig, the layer of sand at the bottom of the bottle should be covered +with moss or cocoa-nut fibre. + +[Illustration: FIG. 57.--A LARVA GLASS.] + +[Illustration: FIG. 58.--A LARVA GLASS.] + +If you find it necessary to move the larvæ yourself from the stale food, +never touch them with your fingers, but lift them gently by means of a +small camel-hair brush. Larger larvæ need never be moved at all. They +will always search out fresh food for themselves, and the stale may be +removed after they have quitted it. + +For rearing larger species ordinary bottles are hardly satisfactory, and +we must either use large jars or construct cages of some kind. + +An ordinary bell jar such as is used for covering ferns or for aquaria +makes a very useful 'larva glass.' Place a small bottle of water at the +bottom, and then introduce sufficient dry clean sand or sifted soil to +reach up to its neck. On the top of this place a layer of moss or +cocoa-nut fibre. Next introduce the food plant, fixing it firmly in the +bottle of water, and plugging up the space between the stem and the rim +with cotton wool. This precaution is to prevent the larvæ from falling +into the water as they attempt to pass up or down the stem, and the wool +also helps to keep the twig in a vertical position. The glass is now +ready for the caterpillars, but it is advisable to keep a covering of +muslin or gauze over the top in all cases even though the larvæ +contained are unable to creep up the surface of glass, for the great +enemies of caterpillars--the ichneumon flies--are always on the alert, +and will often take advantage of an open window to 'sting' the larva +rearer's pets. + +Another form of larva glass can easily be made out of a large glass jar +if you know how to cut off the bottom, or of a chemist's bell jar which +is open both at top and bottom. In this case the bottle of water and the +soil are arranged as before in a pan of unglazed earthenware, and then +covered over with the glass. This is shown in fig. 58, and is an +exceedingly convenient larva house, since the lifting of the glass +enables you to get at the insects without any trouble. + +[Illustration: FIG. 59.--A LARVA CAGE.] + +Wood larva cages are very commonly used for the larger species after +they have attained a fair size and require more food than can be stocked +in bottles and glasses. These cages have glass fronts, either sliding or +in the form of a hinged door, and sides of perforated zinc. They are +kept in stock by all dealers in entomologists' requisites, but equally +useful ones are easily constructed. If you select a box of suitable size +at the grocer's, cut out large pieces from the lid and sides with a fret +saw, and fix in the glass and zinc, you will have a cage that will +answer all purposes. + +The internal arrangements consist of a shallow tray filled with soil, in +which stands the bottle of water for the food, and a layer of moss +sufficiently high to cover the bottle completely. + +A series of such boxes standing on end on a shelf, or hanging on a wall, +will form a very satisfactory nursery for your pets, and will occupy but +little space. + +We have already observed that some larvæ burrow into soil when about to +change, while others creep to a sheltered corner, or suspend themselves +from the food plant itself. It will be seen that the larva cage just +described supplies all these demands, and care must be taken not to +disturb the occupants while they are undergoing their metamorphoses. +Those that suspend themselves on the food plant should be allowed to +remain where they have fixed themselves, and when it is necessary to +remove the stale food in order to give a fresh supply to the later +larvæ, let it be fixed in an airy place where it can be watched till the +perfect insects emerge. Those which suspend themselves on the sides or +top of the cage, or spin cocoons in the corners, should never be +disturbed unless you are greatly in want of the same cage for the +accommodation of another brood; and even then it is possible that their +presence will not in any way interfere with the new species. But if +their removal becomes a necessity, let it be carried out as carefully as +possible, and not until the change to the pupal stage is known to be +complete. + +The species that burrow into the soil or bury themselves in the moss +need never be disturbed till the rearing season is quite over, and then +they may be transferred to a box specially kept for the accommodation of +pupæ. + +There is yet another method of rearing larvæ to which we must refer--a +method known as 'sleeving'--particularly useful when you happen to have +the required food plants in your own garden. The ova or larvæ are placed +on the plant, the whole or part of which is then covered with a bag or +'sleeve' of gauze. The larvæ thus imprisoned have the full benefit of +fresh air and light, and are also free from the attacks of ichneumon +flies. They have a fair amount of liberty, and yet cannot get beyond +your reach; also abundance of fresh food without further trouble on the +part of the rearer. + +But even this arrangement is not perfection. It will not suit the night +feeders that like to hide beneath the soil during the day, and it +interferes somewhat with the burrowing tendencies of those which pupate +underground. These little difficulties, however, can be overcome by +placing the food plants in large pots or tubs of soil, and tying the +mouth of the 'sleeve' round the outside of this utensil. If this cannot +be done, those insects that pupate underground must be removed from the +plant when their restless disposition shows that the changing time has +arrived, and then be transferred to a box of soil where they can find +the seclusion they seek. + +The larvæ that hybernate throughout the winter are rather more +troublesome, especially those which are inclined to take a ramble on +certain mild days in search of food when none is at hand. Still there is +no reason why even a beginner should not attempt the rearing of these. +They will require food in the autumn until the cold weather sets in, and +again early in spring as soon as the new leaves appear; but this is not +of much consequence to those who reside in districts where the required +food plants abound. + +Wood feeders also require some special treatment and precautions, and +the successful rearing of some is a matter of no little difficulty. A +wooden cage is, of course, quite out of the question with these, unless +you wish to test the power of their jaws. They must be kept in large +pots or jars, covered over with wire gauze or perforated zinc, and +supplied with fresh stems or logs of wood, or with moist sawdust fresh +from their favourite tree. A few of them--the 'Goat' (page 224), for +example--will eat dead and rotting wood, and may be fed on old palings +and other waste providing the right kind is selected. + +The troubles and disappointments of larva rearers are numerous and +varied, and commence with the earliest moments of the young insects. +Even the hatching period sometimes proves a trial, for it occasionally +happens that the young larva has not sufficient strength to bite its way +through the shell that surrounds it, and dies with nothing but the +surface of its head exposed to view. This may be the result of keeping +the ova in too dry a spot, the shell having become too hard and horny +for the little creature's jaws. + +Then the moulting seasons are always periods of trial to the larvæ, and +often of loss to the rearer. Some of the hardier species may pass +through all their moults without appearing to suffer anything more than +a slight inconvenience at each, but in other cases the greater part of a +brood may fall victims to these ailments of the growing stage. + +Apart from these sources of loss, however, larvæ are subject to numerous +diseases, infectious and otherwise, about which we know but little. A +fever may rage in one of our cages; a fungoid growth may establish +itself on the bodies of our pets, or we may see them cut down, one by +one, through a fatal attack of diarrh[oe]a. + +In many such cases we are at a loss as to what to do. Blue pills and +black draughts are not to be prescribed, and the modern practices of +surgery and inoculation have not yet been applied to insect patients +with very great success; but we must do our best to adopt hygienic +principles, paying the greatest attention to proper means of ventilation +and to a regular and wholesome dieting. In the case of diarrh[oe]a--a +very common insect malady--the best we can do is to avoid the young and +juicy leaves of the food plant, and substitute the older, and drier +foliage. + +Ichneumon flies have already been mentioned as great enemies of larvæ. +These flies either deposit their eggs on the skins of caterpillars, or +thrust their sharp _ovipositors_ into the creature's flesh and lay their +eggs beneath the skin. When the young ichneumons are hatched, they +immediately begin to feed on the fatty matter that is usually stored in +comparative abundance under the skin of the caterpillar, and thus they +grow at the expense of their host, within whose body they lie completely +hidden from view. + +The poor caterpillar, though being eaten alive, often shows no external +signs of the mischief wrought within, and, even though its substance is +really decreased by the hungry internal parasites, yet the rapid growth +of these robbers maintains the general plumpness of a healthy larva. But +the ichneumons, having at last devoured the store of fat, and avoided +the vital organs of the caterpillar, as if with a view to preserve their +living home to the latest moment, now commence to attack the latter, +speedily reducing the vitality of their host to the lowest ebb, and +finally causing its death. + +This untimely end may come before the caterpillar is full grown, or the +insect may change to the pupa before the ichneumons have done their +worst, but it rarely occurs that the unfortunate creature has sufficient +strength to carry it on to the final stage. + +A large number of the collected larvæ will have been 'stung,' much to +the disgust and disappointment of the rearer; and hence the advantage of +rearing your specimens from ova wherever possible, providing you keep +them so well under cover that the ichneumons cannot visit your broods. + + +_The Management of Pupæ_ + +The disappointments connected with the rearing of _Lepidoptera_ are by +no means at an end when all have passed successfully into the pupal +condition, and the number of perfect insects obtained will often fall +far short of the number of pupæ in your boxes; but we must now see what +can be done to minimise the death rate of the captives. + +One or more suitable boxes must be prepared for the reception of the +pupæ, and the following suggestion will answer all purposes: + +Get a wooden box, quite rough and unplaned inside, large enough to +accommodate your pupæ with ease, and not less than eight inches deep. +Make several holes in the bottom, or else knock the bottom completely +out, and nail in its place a sheet of perforated zinc. Also make a lid +consisting of gauze attached to a light wood frame. + +Place a layer of clean gravel, about an inch deep, in the bottom, and +over this a few inches of sifted soil or cocoa-nut fibre. + +Now take all the pupæ that are 'earthed' in your cages, and arrange them +on the prepared bed; also add to them the pupæ you may have dug out +during your various excursions. Cover all with a layer of the material +selected for the bed, and then add a layer of moss. + +Next come the pupæ that are suspended by silky fibres, or are inclosed +in cocoons. These should be fixed with pins around the sides of the box, +running the pins either through the tuft of silk at the 'tail,' or the +outer layer of the cocoon, or through the portion of the dried food +plant to which they are attached. + +Here your pupæ will remain till they emerge, and the box may be kept in +any airy place where it is not likely to be forgotten, for it is +essential that the perfect insects should be removed as soon as possible +after quitting their cases. It does not matter much whether the pupæ be +kept in or out of doors, providing they are sheltered from rain and very +severe frosts; but of course, if the former, the imagines will emerge a +little earlier, even if the room in which your specimens are stored has +no fire. + +Even when protected in boxes such as that described the pupæ are subject +to enemies and dangers. The soil and moss employed may contain slugs, +mites, or other creatures which prey on insects, and the amount of +moisture present in these materials and in the atmosphere may prove too +little for some species or too much for others. + +The remedy for the former evil is a simple one. Bake the soil or fibre +well before fitting up the box, and boil and afterwards dry the moss. +You may then be sure that all life previously contained is quite +destroyed. + +But the degree of humidity is a point not so easily settled, and so +variable are the experiences and opinions of different entomologists +that it is difficult to advise a beginner on the subject. The fact that +some strongly advise a perennial dampness, while others recommend no +attempt at the application of water, would seem to show that there are +probably important points to be urged on both sides. + +Nothing can be better than a very careful observation of pupæ in their +natural conditions. When engaged in pupa digging you will observe that +the larger number are to be found on the east and north sides of trees +where the soil is protected from the heaviest rains; on the other hand a +good many are certainly found in very moist and sometimes even in wet +situations. + +Particular notice should be taken of such experiences, making every +allowance for the exceptions that prove the rule, and then let the +natural conditions be maintained in your nurseries at home. To carry +this out two pupa boxes should be kept, one for those species that seem +to require dry situations, and the other for the species that apparently +do best with moist surroundings. + +But when it is desired to maintain the pupæ in a moist condition, great +care must be taken not to allow any accumulation of stagnant water. The +box we have described, with its bottom of perforated zinc, is well +adapted for this purpose. Let it stand on a couple of strips of wood, so +that any excess of moisture may readily drain through. The perforated +bottom will also allow of a free circulation of air, thus securing the +ventilation that is desirable in all boxes, whether wet or dry. + +If you have any insects that have pupated within moist stems, they +should be kept in a moist condition till they emerge. The simplest way +of doing this is to support the stems in a layer of wetted but +well-drained silver sand. + +Forcing may be resorted to when it is required to obtain the imagines +for early setting in order to get them in the cabinet before the busy +season begins. The method is simple. Place the pupa box on a shelf in a +room where a fire is kept every day. By this means you may get all your +specimens out within a few weeks, even when you start the forcing at the +beginning or middle of the winter. If, however, you require the imagines +for breeding, you must be careful that the eggs are not laid long before +the buds of the necessary food plants are due. + +When you are expecting the appearance of perfect insects, the pupa +boxes should be examined every day. A morning visit to your pupæ (for +most insects emerge in the morning) may reward you with the sight of a +newly emerged imago, clinging to the rough surface of the box, thus +affording you an opportunity of observing the wonderful expansion of the +wings. But the greeting is not always of such a pleasant character, for +your disappointed eyes will sometimes be cast on a host of horrid +ichneumons that have just quitted a shell from which you were expecting +a prize of some specially valued species. + + + + +CHAPTER IX + +_SETTING AND PRESERVING_ + + +_Setting and Preserving Butterflies and Moths_ + +Up to the present we have been dealing only with living forms--learning +how to catch and rear the Lepidoptera that fall to our lot; but now we +have to become acquainted with the methods of preparing our dead +specimens in such a way that they may form a useful collection for +future study and reference. Our first attention shall be given to the +apparatus necessary for this work. + +The most important requirement is the setting boards, of which several +are necessary, the sizes varying according to the dimensions of the +different insects to be 'set.' The _lengths_ of all the boards should be +the same, not only for the convenience of packing when not in use, but +also in order that they may, if required, be arranged neatly in the +'drying house' to be presently described. The widths only will vary, and +in this respect the boards must be adapted to the measurements of the +insects from tip to tip when the wings are fully expanded. Thus, a set +of a dozen boards, ten or twelve inches long, and from one to five +inches wide, will do for a good start. Of course you may commence with a +smaller number than twelve, but if you really mean to do the thing well, +you will eventually require a good stock of boards. + +Here, again, it may be mentioned that all the necessary requisites may +be purchased ready for use, a set of boards and a drying house complete +costing from ten to twenty shillings according to size and quality; but +as the reader, like myself, may prefer to construct his own, I will +supply him with hints and suggestions sufficient for the work. + +Each board is constructed in this way. Cut out and plane up a piece of +wood of the required length and breadth, and about one-eighth of an inch +thick. Glue on the top of this a layer of cork about half an inch in +thickness, leaving the whole under a moderate pressure until the glue is +quite hard. The sheets of cork for this purpose may be bought at any +naturalist's stores; but slices cut from good large bottle corks may be +made to answer equally well if you don't mind the extra time expended in +cutting and fixing. + +When the glue has well set, trim off the edges of the cork flush with +the sides of the wood, and then cut out a groove down the whole length +of the cork, of course in the middle, and of such a size that it will +just contain the bodies of the insects for which it is intended. + +[Illustration: FIG. 60.--SECTION OF A SETTING BOARD.] + +The satisfactory cutting of this groove is not a very easy matter, but +if its position is first carefully marked, a long rat-tail file may be +made to plough it out neatly and regularly. As an alternative the +following plan is good. First cover the wood with a layer of cork about +a _quarter_ of an inch thick, and then glue on the top of this _two_ +narrower strips, about as thick as the bodies of the insects for which +the board is intended, leaving a space of the required size between +them, as shown in fig. 60. In this way you get a groove of square +section, that is in some respects preferable to the round one cut out by +means of the rat-tail file. + +[Illustration: FIG. 61.--SECTIONS OF SETTING BOARDS.] + +Now comes a question about which there is a difference in the tastes or +fancies of entomologists. Shall the boards be perfectly flat on the top, +or shall the sides slope from the groove, or shall the surface be +rounded? A glance at the three sections of setting boards will show +clearly what is meant. The rounded board is most commonly used, and the +graceful curve thus given to a butterfly or moth set on such is +certainly attractive; but it is not natural. The wings of these insects +are rigid, and are never seen bent into such curves in a living +specimen. For this reason I much prefer a perfectly plane surface on +each side of the groove. Then, as to whether there shall be a slope or +not, this is a matter of less importance. A very decided sloping of the +wings is certainly not so convenient for future examination; nor does +it, to my mind, look nearly so well as both sides in the same plane, or +at a very gentle inclination. But perhaps this subject had better be +left to the taste of the reader, remembering, however, that, whatever +plan be adopted, all the boards should be alike in this respect, so that +there may be a degree of uniformity in the cabinet. + +The surface of the cork must, in all cases, be nicely smoothed down with +glass paper, and then covered with thin white paper, fixed to its +surface with ordinary paste. + +When insects are on the boards, they should be placed in an airy spot, +as free as possible from dust, while they are drying. Hence the +advisability of some form of 'drying house.' This is simply a box, +standing on end, and provided with a hinged door consisting of a sheet +of perforated zinc in a wooden frame. The boards may slide in this on +little slips of wood nailed or glued on to the sides, or the wooden +bases of the boards may project beyond the cork at the ends, and slide +into grooves in the side of the house. + +[Illustration: FIG. 62.--A BUTTERFLY ON THE SETTING BOARD.] + +Beyond these requirements nothing is wanted save a good stock of pins, +thin card or ordinary writing paper, and a 'setting needle.' The +last-named item is simply a needle mounted in a handle, and a good one +may be made by thrusting the head of a darning needle into a piece of +twig. The pins used for setting--that is, for fixing the pieces of paper +or card to keep the parts in position--may be of the ordinary kind; but +entomological pins are far preferable, even for this purpose; for, being +much thinner, they do not damage and disfigure the setting boards so +much. + +Now as to the setting. First see that the pin with which you are to fix +your dead insect passes centrally through the thorax. Then fix it firmly +on the setting board, its body lying neatly in the groove of the cork. +Cut out some little pointed strips of card or paper, and, after bringing +the wings into position with the setting needle, fix each one by a +pinned strip. In spreading out the wings, care must be taken not to +pierce them at all, but simply to push them into their place by pressing +the needle at their bases, or by putting the needle beneath and +_lifting_ them out. + +Instead of pointed pieces of card, uniform strips of paper may be used, +as shown in fig. 63, each strip passing over both wings. + +After the four wings have been properly arranged, a few extra pins may +be used to keep other parts in position. Thus, the antennæ may be placed +at equal angles, the proboscis may be extended, and a couple of pins may +be used to support the abdomen if it is inclined to bend downward. + +[Illustration: FIG. 63.--ANOTHER METHOD OF SETTING BUTTERFLIES AND +MOTHS.] + +As before mentioned, insects should be set soon after they are dead, +while the parts are still soft and supple. But where this cannot be +done, and the specimens have become stiff, brittle, and rigid, they must +be 'relaxed' before any attempt is made at setting them out. + +This process of relaxing consists in placing the specimens in a very +moist atmosphere for a few days. There are several simple ways of doing +this, many of which will readily suggest themselves to the reader. Your +collecting box, if a zinc one, may also be used as a relaxer. Pin your +stiff insects in it, after well moistening the cork, and simply shut +them up for a day or two. Any metal box will serve the same purpose +providing you put into it a piece of sheet cork on which to fix the +insects, and this cork may rest on a bed of moist sand. + +Another plan is to float the pinned specimens on corks in a shallow +vessel of water, and cover them over with a bell glass. + +Insects that are being relaxed should be examined from time to time, and +the degree of flexibility acquired tested by a gentle pressure of the +setting needle or by blowing on them. If not sufficiently supple, give +another day in the damp cell, but never allow them to be forgotten till +they are covered with mildew. + +The time occupied in thoroughly drying butterflies and moths will vary +considerably according to their sizes and the condition of the +atmosphere. In hot and dry summer weather four or five days will prove +quite sufficient for the _very_ small and thin-bodied species. From one +to two weeks, however, may be looked upon as the average period; but the +large and thick-bodied moths may require more than this. + +Perhaps the best test of their condition is the gentle pressing of the +setting needle against the abdomen--the last part of the body to become +dry and stiff. If the abdomen seems quite firm and rigid, you are pretty +safe in removing the specimen from the board; but if it bends at all +under a slight pressure of the needle let it remain for a day or two +longer. + +If your cabinet is quite ready for the reception of new-comers, the +insects may be put in their proper places immediately after their +removal from the setting boards; but if not, they may be pinned +temporarily in a 'store box' till the time comes when you have proper +accommodation provided. The full consideration of these matters will be +dealt with in another chapter. + +It is possible that the setting of some of your specimens will not +exactly please you. If such is the case, put them in a relaxing box for +a day or two, and then reset them more to your fancy. + +We have now to deal with a matter that applies more particularly to +moths, especially the very large and thick-bodied species. The abdomens +of these become more or less contracted and shrivelled on drying, +sometimes to such an extent as to look most unsightly. + +There is a remedy for this, and the time and patience required in +working it out will be well repaid by the superior results obtained. + +While the abdomen is still in a soft condition, make a slit throughout +its length with a very sharp knife or a sharp-pointed pair of scissors. +This slit should be made down the centre of the under surface, or, if +the insect is to be placed in the cabinet with the under side exposed, +down the middle line of the back. Then remove all the contents of the +abdomen, scraping them out with a piece of hooked wire, or removing them +with a fine pair of forceps, and leaving the skin as clean as possible +both within and without. Now introduce a packing of cotton wool, just +sufficient in quantity to maintain the natural form of the body as the +specimen dries. + +There is another good method of stuffing moths that possesses a decided +advantage over the one just described, since it leaves the specimen in +such a perfect condition that it shows no appearance of having been +stuffed when viewed from either side. This consists in snipping off the +abdomen at the waist, clearing out the contents with a hooked wire, +lightly stuffing it with cotton wool pushed in at the waist, and then +setting it aside to dry, while the other part of the insect is +undergoing the same process on the setting board. When both parts of the +moth are thoroughly dry, the stuffed abdomen is easily fixed in its +place with a little coaguline; and this, if neatly done, will not show +the slightest sign of the treatment to which the insect has been +submitted. + +Even after your insects are finally housed in the cabinet, they are +subject to two other dangers, both of which are more destructive to +moths than to butterflies. One is technically known as 'grease,' and the +other is the invasion of certain museum pests that feed on the +specimens, causing them to fall to pieces. + +Examine the moths that have been for a time in the cabinet, and some are +sure to exhibit an oily or greasy appearance, the hairs of the abdomen, +and perhaps also of the thorax, being clogged together just as if the +specimen had been dipped in oil, the same miserable condition perhaps +being shared also by parts of the wings. + +This is due to the gradual oozing out of the fatty matter that is always +present to a greater or less extent in the bodies of the insects, and +which must necessarily show itself more sparingly in specimens that have +been carefully stuffed. + +The old saying, 'Prevention is better than cure,' applies well in the +present case; but as there are times when a knowledge of the 'cure' is +the only means of saving a valuable specimen from destruction, we will +study both. + +To deal with the two in the order of the well-worn proverb, we will +consider the prevention first. Always carefully clean out and stuff the +abdomens of large-bodied insects; and as a rule, treat them with some +substance that will either absorb or dissolve out all oily matter. I +think the best plan is to remove the abdomen, clean it out if its size +permits of such an operation, and then, after labelling it to prevent +its future application to the wrong body, either let it remain in a +bottle of magnesia for several weeks, or soak it in benzole or ether for +a few hours or longer. + +If magnesia has been employed as an absorbent, you have simply to blow +or lightly brush off the loose powder that clings to the body, and then +fix it in its place with coaguline. A body dipped in ether or benzole +will look as if completely spoilt at first, for the furry coat that +clothes it will lie matted and almost entirely robbed of its beautiful +colours, reminding one forcibly of the proverbial 'drowned rat.' But +take no notice of this change. Let the body have at least a few hours in +the liquid, extending the time to a day or two in the case of very large +ones and those which experience has proved to be particularly liable to +'grease;' and, immediately on withdrawing it, fix it with a pin in a +good strong draught, such as you may obtain by opening a window about an +inch, or, if a breezy day, in the open air. + +These liquids are so volatile (and for that reason should never be left +exposed in an open vessel) that they rapidly evaporate, leaving the dry +hair to be loosened by the breeze, thus bringing back the natural +appearance almost perfectly. + +It is probable that many of the smaller insects that were not considered +to require the stuffing or grease-removing operations will sooner or +later exhibit a greasy tendency in the cabinet. At first the abdomen is +affected, and the oily matter then gradually creeps over the rest of the +body, finally spreading over the wings, and giving the insect a most +deplorable aspect. But these are not irreparably lost, and the following +cure will often bring them back to their former beauty. + +If the abdomen only shows signs of grease, cut it off and soak it in one +of the above-named liquids for a day or so, replacing it as above after +the drying operation. If, however, the oily matter has spread to the +thorax and the bases of the wings, the whole specimen must be soaked, +using a basin or jar of suitable size, covered with a plate of glass. A +good draught during the drying operation will do much to prevent the +hair from sticking in matted tufts close against the surface of the body +and wings, and a gentle brushing with a very soft camel-hair brush will +loosen and reset the fur. + +The other danger to which we have referred is the invasion of certain +'mites' and other museum pests that pay periodical visits to our cabinet +drawers and store boxes, often committing such havoc as to severely try +the patience of an interested naturalist. + +The way to prevent such intrusions is to make the atmosphere of the +compartments so obnoxious (to them) that they dare not enter; and, +further, to so spice up your specimens that they are no longer safely +edible to the invaders. + +The first object can be attained by always keeping camphor or +naphthaline (albo-carbon) in each division. A lump of either substance +may be secured by pins or a little perforated cell in the corner of each +drawer or box, or the bottom of each may be dusted with finely powdered +naphthaline; but as both these solids are volatile, care must be taken +to renew the supply as occasion requires. + +Then, with regard to the second precaution, perhaps nothing is more +effectual than corrosive sublimate. A little of this may be dissolved in +a small bottle of alcohol (spirits of wine), labelled with the name and +the word POISON, and kept ready for use. All the skins of stuffed +specimens should be painted with this solution, and the stuffing itself +may be moistened with it before insertion. + +There is yet another circumstance that renders a watchful care of your +cabinet specimens necessary, if you happen to possess many that were +captured 'at sugar.' Some of these will have so gorged themselves with +syrup that they are literally full of it, and this will sometimes find +its way to the outside, often dropping on the surface beneath. In such +cases the sugar should be removed as completely as possible, and the +bodies stuffed, before they are quite dry; but if the specimens have +been in the cabinet so long that they are stiff and hard, the under +sides of the abdomens may be completely cut out with a very sharp knife +and thrown away, and then the sugar cleaned out from the upper shell as +neatly as possible. + + + + +CHAPTER X + +_PRESERVING OVA, LARVÆ AND PUPÆ_ + + +Many young entomologists give their attention almost solely to the +perfect forms of insects, often collecting and studying a very large +number of species without regard to their earlier stages and +metamorphoses. This is decidedly a very great mistake. Although the +lifeless form pinned in a cabinet may be a most beautiful object in +itself, yet a study of this alone is uninteresting compared with that of +the wonderful changes it has undergone since the time it was a very +young larva. + +The different stages of the insects should be known as far as possible, +and these, as well as the perfect forms, should be included in the +collection for future study and reference. A good cabinet, according to +my own opinion, is one that possesses, among other good features, a +number of complete sets illustrative of the life history of at least the +more typical forms; and as it is not a difficult matter to preserve the +earlier stages, there is really no excuse for their omission from the +collection. + +The empty shells of ova are in themselves sometimes interesting objects, +especially when they illustrate some peculiar instinct on the part of +the parent. Sterile eggs, also, often fall into the hands of breeders +and rearers, and these, though in other respects unprofitable, are +useful in the cabinet. + +If fertile eggs are to be prepared for a collection, they must be +killed. This is easily done by thrusting into each one the point of a +very fine needle, or by immersing them for a moment in boiling water, or +by shutting them up in a bottle with camphor. In drying they often +contract more or less, and frequently change their colour; still these +are useful, providing notes have been taken of the characters thus lost. +The larger eggs are capable of special treatment where the owner has the +necessary time and patience, and where the highest results are desired. +By means of a surgeon's injector of small size the contents of the eggs +can be removed; and then, by the same instrument, a warm solution of +gelatine, coloured in such a way as to restore the natural tint, may be +forced into the empty shell. As the gelatine cools and hardens, it +prevents any shrinking of the shell, and thus both form and colour are +well preserved. + +For the preservation of larvæ you will require one or two simple +appliances. + +The first of these is a suitable glass blowpipe, one form of which is +here illustrated. It consists of a glass tube, one end of which has been +drawn out very fine; a piece of watch spring tied to it in such a manner +that it will hold the skin of a larva at the small end, and a piece of +india-rubber tubing at the other end, pressed by means of a brass spring +clip. + +[Illustration: FIG. 64.--A BLOWPIPE FOR LARVÆ.] + +A little drying oven is also very useful, but not absolutely necessary. +If you decide to have one, any square box of sheet iron (not soldered +tinned iron) may be readily converted into one. It must be provided with +a hinged door in the front with a ventilator at the bottom, a hole for +the escape of hot air at the top, and a tripod wire stand inside on +which to rest the specimens while drying. The whole should be supported +on a wire stand, so that heat may be applied below. + +Each larva to be preserved should be dealt with in this way. First kill +it by means of any one of the killing bottles or boxes already +described, or by immersion in spirit of wine. When quite dead, enlarge +the anal orifice by thrusting a needle into it, and then lay it on a +piece of blotting paper with its head toward you. Now take a round +ruler, previously covered with blotting paper, and roll the larva gently +from head to tail till all the contents of the skin have been expelled. +Next fix the skin on the fine end of the blowpipe, by thrusting the +point of the latter into the opening, and allowing the spring to press +gently on its edge. Gently blow into the skin till it is inflated just +to a _little below_ natural size, then either hold it near a fire or +rest it in the drying oven till it is quite dry and rigid. + +If you have done your work neatly, the skin and blowpipe will both be +quite air-tight when the clip is closed; and the air, finding no outlet, +will still further inflate the skin when it expands on exposure to heat. +This is the reason why you are directed to blow it out to something +short of the natural dimensions. If you find that this expansion causes +the skin to stretch beyond its normal size, a little of the air must be +allowed to escape while it is yet soft and flexible. + +The front of the larva is generally the last portion to become dry, and +when this is quite rigid the skin may be removed from the blowpipe. This +is a matter that requires the greatest care; for the skin is so very +thin and brittle that a little rough handling will break it to pieces. +As a rule it may be easily pushed off the pipe by a slight pressure +behind, or a gentle twisting motion will loosen its hold; but this +latter method can hardly be applied to hairy larvæ without breaking off +the hairs, now rendered very brittle by the heat. + +If you find the slightest difficulty in detaching the skin of a valuable +specimen, it is far better to damage the blowpipe than to risk spoiling +the skin. Supposing your blowpipe is a glass one, you can easily break +off the end of it after making a cut with a very small triangular file, +and the portion thus removed may be left attached to the skin. Then, +after softening the glass blowpipe in a gas flame or the flame of a +spirit lamp, it can be drawn out thin again for future work. Those who +can manipulate glass tubing in this way will find it far better to lay +in a stock of suitable material, drawing it out when required, than to +purchase blowpipes ready made at the naturalist's shop. + +Very fine hollow stems, such as those of the bamboo cane, may be used +instead of glass; and these possess the advantage of being easily cut +with a sharp knife when there is any difficulty in removing the skin. +Again, whether glass or fine stems are used, a little grease of any kind +placed previously on the end will allow the dried skin to be slid off +with less difficulty. + +Preserved larvæ should preferably be mounted on small twigs or +artificial imitations of the leaves of the proper food plants. A little +coaguline applied to the claspers will fix them very firmly on these +twigs or leaves, which are then secured in the cabinet by means of one +or two small pins. + +It is much to be regretted that the natural colours of many caterpillars +cannot be preserved in the blown skins. Some are rendered much lighter +in colour on account of the withdrawal of the contents, while others +turn dark during the drying. In the smooth-skinned species the natural +tints may be restored by painting or by staining with suitable aniline +dyes, but these artificial imitations of the natural colours are always +far less beautiful than the hues of the living larvæ. + +Very few words need be said on the preservation of pupæ. Many of them do +not alter much in form and colour, and therefore they require no special +preparation. + +If a pupa has to be killed for the purpose of adding to the value of the +collection, simply plunge it into boiling water, and it is ready to be +fixed in the cabinet as soon as it is quite dry. + +The empty pupa cases, too, from which the perfect insects have emerged, +are often worth preserving, especially if the damage done by the imago +on forcing its way out is repaired with the aid of a little coaguline. + +Let all larvæ and pupæ be preserved in their characteristic attitudes +and positions as far as possible, so that each one tells some +interesting feature of the life history of the living being it +represents. Further, enrich your collection by numerous specimens of the +various kinds of cocoons constructed by the larvæ, pinning each one +beside its proper species; and never refuse a place to any object that +relates something of the life history of the creatures you are +studying. + + + + +CHAPTER XI + +_THE CABINET_--_ARRANGEMENT OF SPECIMENS_ + + +The selection of a cabinet or other storehouse for the rapidly +increasing specimens of insect forms is often a matter of no small +difficulty to a youthful entomologist. Indeed, there are very many +points of considerable importance to be considered before any final +decision is made. Freedom from dust, the exclusion of pests, the +convenience of the collector, the depth of his pocket, and the general +appearance of the storehouse must be considered, and it is impossible, +therefore, to describe a form that is equally suitable to all. + +If it is absolutely necessary that the cabinet (or its substitute) be of +a very inexpensive character, and if, at the same time, the collector +has not the mechanical skill necessary for its construction, then +perhaps the best thing he can do is to procure a number of shallow +(about an inch and a half deep) cardboard, glass-topped boxes, such as +are to be obtained at drapers' shops. For the sake of uniformity and +convenience in packing, have them all of one size. Glue in small slices +of cork just where the insects are to be pinned, and see that each box +is supplied with either camphor or naphthaline. All the boxes may be +packed in a cupboard or in a case made specially to contain them; and a +label on the front of each will enable you to select any one when +required without disturbing the others. + +It may be mentioned here that glass is not necessary, though it is +certainly convenient at times, especially when you are exhibiting your +specimens to admiring non-entomological friends, who have almost always +a most alarming way of bringing the tip of the first finger dangerously +near as they are pointing out their favourite colours. 'Isn't _that_ one +a beauty?' is a common remark, and therewith off snaps a wing of one of +your choicest insects. When glass is used, however, see that the +specimens are excluded from light, or the colours will soon lose their +natural brilliancy. + +Anyone who has a set of carpenter's tools and the ability to use them +well will be able to construct for himself either a set of store boxes +or a cabinet of many drawers in which to keep his natural treasures. In +this case a few considerations are necessary before deciding on the form +which the storehouse is to take. + +A cabinet, if nicely made, forms a very sightly article of furniture; +and, if space can be found for it, is the best and most convenient +receptacle. One of about twelve to twenty drawers will be quite +sufficient for a time; and the few following hints and suggestions may +be useful. + +The wood used should be well seasoned, and free from resin. The drawers +should fit well, and slide without the least danger of shaking. Each one +should be lined with sheet cork, about one-eighth of an inch thick, +glued to the bottom, nicely levelled with sand paper, and then covered +with thin, pure white paper, laid on with thin paste. It is also +advisable to cover each with glass, inclosed in a light wood frame that +fits so closely as to prevent the intrusion of mites. + +The drawers may be arranged in a single vertical tier if the cabinet is +to stand on the floor, or in two tiers if it is to be shorter for +placing on the top of another piece of furniture; and glass doors, +fastened by a lock and key, may be made to cover the front if such are +desired as a matter of fancy, or as a precaution against the meddlesome +habits of juvenile fingers. + +Store boxes are sometimes chosen in preference to cabinets because they +are more portable, and because they can be arranged on shelves--an +important consideration when floor space is not available. + +These boxes should be cork-lined and glazed like the cabinet drawers; +and if they are made in two equal portions, lined with cork on both +sides, and closing up like a book, they may be arranged on shelves like +books, in which position they will collect but little dust. + +Both store boxes and cabinets are always kept in stock by the dealers, +the former ranging from a few shillings each, and the latter from +fifteen shillings to a guinea per drawer. Knowing this, you can decide +for yourself between the two alternatives--making and purchasing. + +We have now to consider the manner in which our specimens should be +arranged and labelled. + +The table forming Appendix I contains the names of _all_ the British +butterflies and larger moths, and shows their division into _Sections_, +_Tribes_, _Families_, and _Genera_. This table is the result of most +careful study on the part of leading entomologists, and shows how, in +their opinion, the insects can best be arranged to show their relation +to one another; and you cannot do better than adopt the same order in +your collection. + + RHOPALOCERA + PAPILIONIDÆ _Euchloë_ NYMPHALIDÆ + _Papilio_ O O O _Argynnis_ + O O O O O + O O O O O + O O O O O + Machaon Rapæ Cardamines Edusa O + Selene + PIERIDÆ O _Leucophasia_ O + _Aporia_ O O O O + O O O v.

These, when cut up, supply you with neat labels for your +specimens. + +If you intend to study the British _Lepidoptera_ as completely as +possible, you may as well start at once with a sufficiently extensive +cabinet, and arrange all the labels of your list before you introduce +the insects. You will thus have a place provided ready for each specimen +as you acquire it, and the introduction of species obtained later on +will not compel you to be continually moving and rearranging the +drawers. + +Probably the number of blank spaces will at first suggest an almost +hopeless task, but a few years of careful searching and rearing will +give you heart to continue your interesting work. + +Arrange all the insects in perpendicular rows. Put the names of each +section, tribe, family, and genus _at the head_ of their respective +divisions, and the names of the species below each insect or series of +insects. The opposite plan, in which the circles represent the insects +themselves, will make this clear. + +Three or four specimens of each species are generally sufficient, except +where variations in colouring are to be exhibited. Wherever differences +exist in the form or markings of the sexes, both should appear; and one +specimen of each species should be pinned so as to exhibit the under +side. + +Finally, each drawer or box should have a neat label _outside_ giving +the name or names of the divisions of insects that are represented +within. This will enable you to find anything you may require without +the necessity of opening drawer after drawer or box after box. + + + + +PART III + +BRITISH BUTTERFLIES + + +We have now treated in detail of the changes through which butterflies +and moths have to pass, and have studied the methods by which we may +obtain and preserve the insects in their different stages. I shall now +give such a brief description of individual species as will enable the +reader to recognise them readily. We will begin with the butterflies. + + + + +CHAPTER XII + +_THE SWALLOW-TAIL AND THE 'WHITES'_ + + +Family--PAPILIONIDÆ + +_The Swallow-tail_ (_Papilio Machaon_) + +Our first family (_Papilionidæ_) contains only one British species--the +beautiful Swallow-tail (_Papilio Machaon_), distinguished at once from +all other British butterflies by its superior size and the 'tails' +projecting from the hind margin of the hind wings. + +This beautiful insect is figured on Plate I, where its bold black +markings on a yellow ground are so conspicuous as to render a written +description superfluous. Attention may be called, however, to the yellow +scales that dot the dark bands and blotches, making them look as if they +had been powdered; also to the blue clouds that relieve the black bands +of the hind wings, and the round reddish orange spot at the anal angle +of each of the same wings. + +It appears that this butterfly was once widely distributed throughout +England, having been recorded as common in various counties, and has +also been taken in Scotland and Ireland; but it is now almost +exclusively confined to the fens of Cambridgeshire, Huntingdonshire, +and Norfolk. Occasionally we hear of the capture of single specimens +quite outside these localities, sometimes even in most unlikely spots, +where its food plant does not abound. But we know that _Machaon_ is a +general favourite with entomologists, and that it is sent in the pupal +state, by post, to all parts of the kingdom; so that the occasional +capture of the insect far beyond the borders of its haunts is probably +the outcome of an escape from prison, or of the tender-heartedness of +some lover of nature who could not bear to see such a beautiful creature +deprived of its short but joyous, sunny flight. + +You cannot hope to see this splendid butterfly on the wing unless you +visit its haunts during its season--May to August; but the pupæ may be +purchased for a few pence each from most of the entomological dealers; +and if you obtain a few of these and watch them closely, you may be +fortunate enough to see the perfect insect emerge from its case, and +witness the gradual expansion of its beautiful wings. + +The pupa (Plate VIII, fig. 7) itself is a most beautiful object. Its +colour is a pale green, and it is fixed to its support by the tail, and +further secured by a very strong silk band. + +The larva (Plate VIII, fig. 1), too, is exceedingly beautiful. Its +ground colour is a lovely green, and twelve velvety black rings mark the +divisions between the segments. Between these are also black bars, all +spotted with bright orange except the one on the second segment. + +A remarkable feature of this larva is the possession of a forked, +Y-shaped 'horn,' that is projected from the back, just behind the head, +when the creature is alarmed. If it is gently pressed or irritated in +any way, this horn is thrust out just as if it were an important weapon +of defence. And perhaps it is, for it is the source of a powerful odour +of fennel--one of the food plants of the caterpillar--that may possibly +prove objectionable to some of its numerous enemies. + +The food plants of _Machaon_ are the milk parsley or hog's fennel +(_Peucedanum palustre_), cow-parsnip (_Heracleum sphondylium_), and the +wild angelica (_Angelica sylvestris_); but in confinement it will also +partake of rue and carrot leaves. + +The caterpillar of this species may be found in the fens during the +greater part of the summer. It turns to a chrysalis in the autumn, and +remains in this state throughout the winter, attached to the stems of +reeds in the vicinity of its food plants. The perfect insect is first +seen in May, and is more or less abundant from this time to the month of +August. + + +Family--PIERIDÆ + +This family, though known commonly as the 'Whites,' contains four +British species that display beautiful tints of bright yellow or orange. + +In many respects the _Pieridæ_ resemble the last species. Thus the +perfect insects have six fully developed legs; the caterpillars are +devoid of bristles or spines; and the chrysalides are attached by means +of silky webs at the 'tails,' and strong cords of the same material +round the middle. + +All the larvæ are also cylindrical or wormlike in shape; and their skins +are either quite smooth, or are covered with very short and fine hairs, +that sometimes impart a soft, velvety appearance. + +The members of this family are remarkable for their partiality for +certain of our cultivated plants and trees; and are, in some cases, so +abundant and so voracious, that they are exceedingly destructive to +certain crops. + + +_The Black-veined White_ (_Aporia Cratægi_) + +This butterfly may now be regarded as one of our rarities. At one time +it was rather abundant in certain localities in England, among which may +be mentioned the neighbourhoods of Cardiff and Stroud, also parts of +Kent, Sussex, Hampshire, Huntingdonshire, and the Isle of Thanet; but it +is to be feared that this species is nearly or quite extinct in this +country. It is well, however, not to give up the search for it, and if +you happen to be in one of its favoured localities of former days, you +might net all the doubtful 'Whites' of large size that arouse your +suspicions, liberating them again if, on inspection, they do not answer +to the description of the species 'wanted.' This course becomes +absolutely necessary, since the Black-veined White is hardly to be +distinguished from the Common Large White while on the wing. + +If you examine a number of British butterflies you will observe that in +nearly all species the wings are bordered by a fringe of hair, more or +less distinct. But the case is different with _Cratægi_. Here they are +bordered by a black nervure, without any trace of fringe, thus giving an +amount of rigidity to the edges (see Plate I, fig. 2). + +The wing rays, or nervures, are very distinct--a feature that gave rise +to the popular name of the butterfly. In the male they are quite or +nearly black, but those of the fore wings of the female are decidedly +brown in colour. At the terminations of the wing rays there are +triangular patches of dark scales, the bases of which unite on the outer +margins of the wings. + +Another peculiar feature of this insect is the scanty distribution of +scales on the wings. This is particularly so in the case of the female, +whose wings are semi-transparent in consequence. + +The butterfly is on the wing during June and July, at which time its +eggs are laid on the hawthorn (_Cratægus Oxyacantha_) or on fruit +trees--apple, pear and plum. + +A vigorous search of these trees in the proper localities _may_ reveal +to you a nest of the gregarious larvæ, all resting under the cover of a +common web of silk. These remain thus under their silken tent throughout +the hottest hours of the day, and venture out to feed only during the +early morning and in the evening. + +When the leaves begin to fall in the autumn, they construct a more +substantial web to protect themselves from the dangers of the winter, +and in this they hybernate till the buds burst in the following spring. +They now venture out, at first during the mildest days only, and feed +voraciously on the young leaves, returning to their homes to rest. Soon, +however, they gradually lose their social tendencies, till at last, when +about half or three-quarters fed, they become quite solitary in their +habits. + +In May they are fully grown, and change to the chrysalis state on the +twigs of their food trees. + +The larva is black above, with two reddish stripes. The sides and under +surface are grey, the former being relieved by black spiracles. + +The pupa (page 45) is greenish or yellowish white, striped with bright +yellow, and spotted with black. + +It is probable that the reader will never meet with this insect in any +of its stages. But, though it may have left us, it is still very +abundant on the Continent, where it does great damage to fruit trees; +and the foreign pupæ may be purchased of English dealers. + + +_The Large White_ (_Pieris Brassicæ_) + +We pass now from one of the rarest to one of the most abundant of +British butterflies. Everybody has seen the 'Large White,' though we +doubt whether everybody knows that this insect is not of the same +species as the two other very common 'Whites.' The three--Large, Small, +and Green-veined--are so much alike in general colour and markings, and +so similar in their habits and in the selection of their food plants, +that the non-entomological, not knowing that insects do not grow in +their perfect state, may perhaps regard the larger and the smaller as +older and younger members of the same species. But no--they are three +distinct species, exhibiting to a careful observer many important marks +by which each may be known from the other two. + +On Plate I (fig. 3) will be seen a picture of the female _Brassicæ_, in +which the following markings are depicted: On each fore wing--a blotch +at the tip, a round spot near the centre, another round one nearer the +inner margin, and a tapering spot on the inner margin with its point +toward the base of the wing. On the hind wings there is only one spot, +situated near the middle of the costal margin. + +The male may be readily distinguished by the absence of the black +markings on the fore wings, with the exception of those at the tips. He +is also a trifle smaller than his mate. + +This butterfly is double-brooded. The first brood appears in April and +May, the second in July and August; and the former--the spring +brood--which emerges from the chrysalides that have hybernated during +the winter, have _grey_ rather than black tips to the front wings. + +The ova of _Brassicæ_ may be found on the leaves of cabbages in every +kitchen garden, also on the nasturtium, during May and July. They are +pretty objects (see fig. 10), something like little bottles or +sculptured vases standing on end, and are arranged either singly or in +little groups. + +As soon as the young larvæ are out--from ten to fifteen days after the +eggs are deposited--having devoured their shells, they start feeding on +the selfsame spot, and afterwards wander about, dealing out destruction +as they go, till little remains of their food plant save the mere stumps +and skeletons of the leaves. + +The ground colour of the caterpillar is bluish green. It has a narrow +yellow stripe down the middle of the back, and two similar but wider +stripes along the sides; and the surface of the body is rendered +somewhat rough by a number of small black warty projections, from each +of which arises a short hair. + +When fully grown, it creeps to some neighbouring wall or fence, up which +it climbs till it reaches a sheltering ledge. Here it constructs its +web and silken cord as already described (page 36), and then changes to +a bluish-white chrysalis, dotted with black. The butterflies of the +summer brood emerge shortly after, but the chrysalides of the next brood +hybernate till the following spring. + +It is remarkable that we are so plagued with 'Whites' seeing that they +have so many enemies. Many of the insect-feeding birds commit fearful +havoc among their larvæ, and often chase the perfect insects on the +wing, but perhaps their greatest enemy is the ichneumon fly. + +Look under the ledges of a wall of any kitchen garden, and you will see +little clusters of oval bodies of a bright yellow colour. Most gardeners +know that these are in some way or other connected with the caterpillars +that do so much damage to their vegetables. They are often considered to +be eggs laid by the larvæ, and are consequently killed out of pure +revenge, or with a desire to save the crops from the future marauders. + +No greater mistake could be made. These yellow bodies are the silken +cocoons of the caterpillar's own foes. They contain the pupæ of the +little flies whose larvæ have lived within the body of an unfortunate +grub, and, having flourished to perfection at the expense of their host, +left its almost empty and nearly lifeless carcase to die and drop to the +ground just at the time when it ought to be working out its final +changes. Often you may see the dying grub beside the cluster of cocoons +just constructed by its deadly enemies. Should you wish to test the +extent of the destructive work of these busy flies, go into your garden +and collect a number of larvæ, and endeavour to rear them under cover. +The probability is that only a small proportion will ever reach the +final state, the others having been fatally 'stung' before you took +them. + + +_The Small White_ (_P. Rapæ_) + +This butterfly closely resembles the last species except in point of +size. The male, represented on Plate I (fig. 4), has a dark grey blotch +at the tip of each fore wing, a round spot of the same colour beyond the +centre of that wing, and another on the costal margin of the hind wing. +The female may be distinguished by an additional spot near the anal +angle of the fore wing. + +Although this and the two other common butterflies (_Brassicæ_ and +_Napi_) that frequent our kitchen gardens are usually spoken of as +'Whites,' a glance at a few specimens will show that they are not really +white at all, but exhibit delicate shades of cream and yellow, inclining +sometimes to buff. The under surfaces are particularly noticeable in +this respect, for here the hind wings and the tips of the fore wings +display a very rich yellow. + +The species we are now considering is also very variable both in its +ground colour and the markings of the wings. The former is in some cases +a really brilliant yellow; and the latter are in some cases entirely +wanting. + +_Rapæ_ is double-brooded, the first brood appearing in April and May, +and the other in July and August. + +During these months the eggs may be seen in plenty on its numerous food +plants, which include the cabbages and horse-radish of our gardens, also +water-cress (_Nasturtium officinale_), rape (_Brassica Napus_), wild +mustard (_B. Sinapis_), wild mignonette (_Reseda lutea_), and nasturtium +(_Tropæolum majus_). + +The eggs are conical in form--something like a sugar loaf, with ridges +running from apex to base, and very delicate lines from ridge to ridge +transversely. + +The young larvæ often make their first meal of the shell, and then +attack the food plant so voraciously that they are fully grown in about +three or four weeks. In colour they are of a beautiful glaucous green, +hardly distinguishable at times from the leaves on which they rest. A +yellow stripe runs along the middle of the back, and lines of yellow +spots adorn the sides; and the whole body is covered with very short +hairs, each one arising from a minute warty projection. + +The pupæ may be found during the same seasons and in the same situations +as those of _Brassicæ_. They are very variable in colour. Some are of a +very pale grey or putty colour, some are decidedly brown, and others of +a greenish tinge; and they are often spotted and striped with dark grey +or black. + + +_The Green-veined White_ (_P. Napi_) + +A non-observant beginner at entomological work may easily mistake this +insect for the last species, for the ground colour and markings are very +similar, even to the features by which the sexes are distinguished from +each other; but an inspection of the under surface will give a ready +means of identification, for here the wing rays are bordered with black +scales which, by contrast with the rich yellow around them, often +appear of a greenish hue. The butterfly receives its popular name from +this circumstance. + +A careful observer, however, will readily find distinguishing marks on +the upper side, for here also the chief 'veins' are more or less +accompanied with black scales, especially the extremities of those of +the fore wings, where little triangular blotches are often distinctly +formed; and the dark veining of the under surface of the hind wings +frequently shows through. The under side of this insect is shown on +Plate I (fig. 5). + +This butterfly is not so abundant as the two preceding, but is widely +distributed throughout England, and is in most parts decidedly +plentiful. + +The first brood (for it also is double-brooded) appears during April and +May, and the second in July and August. + +The eggs are very similar to those of _Rapæ_, resembling ribbed and +striated sugar loaves; and the larvæ are of the same rich glaucous +green, but may be identified by the black spiracles surrounded by yellow +rings. In our gardens we may find both eggs and larvæ on mignonette and +horse-radish; the other food plants of this species include the +water-cress (_Nasturtium officinale_), winter cress (_Barbarea +vulgaris_), rape (_Brassica Napus_), cuckoo-flower (_Cardamine +pratensis_), and Jack-by-the-hedge (_Sisymbrium Alliaria_). + +The pupa is greenish, and marked with small black dots. + + +_The Bath or Green-chequered White_ (_P. Daplidice_) + +There is no doubt that many butterflies migrate from one country to +another across the seas; and as the Bath White is very common on the +other side of the Channel, and has been taken very sparingly in England +almost exclusively in the south-east, it is highly probable that the +majority of those that have been captured here are specimens that have +taken a voluntary trip across the water, or have been blown over during +rough weather. + +This butterfly is one of our greatest rarities, and the capture of a +specimen in England is an event that must necessarily be recorded in our +entomological literature. It seems that _Daplidice_ has bred in England, +for its caterpillars have been found at large on one or two occasions, +so I will give a short description of the various stages of the insect, +with a hope that some of my readers may be fortunate enough to meet with +it. + +The female butterfly is shown on Plate I, fig. 6. From this it will be +observed that each of the fore wings is tipped with a rather large +smoky-black blotch, in which are four white spots. A double spot of the +same colour also occupies a place near the centre of the wing, and +another smaller and round one lies near the anal angle. The hind wings +are clouded with grey, and bordered along the hind margin with distinct +smoky-black spots. + +The male may be distinguished from the female by the absence of the spot +near the anal angle of the fore wings, and of all the clouds and spots +of the hind wings. Nevertheless the latter have a decidedly clouded +appearance, but this is due to the markings of the under surface showing +through them. + +The under side of both sexes is most beautifully marked--the fore wings +resembling the upper sides, but the hind pair chequered with a beautiful +soft green on a pale yellow ground. + +The eggs of this insect are deposited during April and May, and again in +August or September--for it is, like the other 'Whites,' +double-brooded--on two species of Wild Mignonette (_Reseda lutea_ and +_R. luteola_). + +[Illustration: FIG. 65.--THE BATH WHITE--UNDER SIDE.] + +The caterpillars, which are of a bluish colour, with two yellow stripes +down the back, and two others along the sides, may be _looked_ for in +June and September. Those of the first brood only have been taken in +this country, while the others on the Continent change to the chrysalis +in the autumn, and hybernate in this state throughout the winter. + +The chrysalis is of a brownish colour, and closely resembles that of the +Small White in form. + +Those in search of this rare British insect should wander along the +south-east coast, and net all the doubtful slow-flying small Whites +(_Daplidice_ is rather slow and heavy on the wing), and their +perseverance _may_ be rewarded with a prize that will ever be a reminder +of a glorious catch and an eventful day. If you fail in this, and most +probably you will, rather than remain a stranger to this beautiful and +interesting insect, fill up the blank in your cabinet with a foreign +specimen, which can be obtained at any time for a few pence, but be +careful to label it 'not British,' in order that your brother +collectors may not be deceived, or be led to make any unnecessary +inquiries. + + +_The Orange Tip_ (_Euchloë Cardamines_) + +No one could possibly mistake the male of this species for any other +British butterfly, the popular name alone giving quite sufficient +information for its identification, but the female Orange Tip is _not_ +tipped with orange, and its markings, both above and beneath, resemble +those of _Daplidice_ so nearly that the same written description might +apply almost equally well to both. + +On Plate I (fig. 7) is shown the upper side of the male, and just +opposite it (fig. 8) the under surface of the same. The female is +usually a little larger than her mate, and is marked similarly on both +sides except that the bright orange blotch is entirely wanting. She may +always be distinguished from _Daplidice_ by the smaller size of the +white spots that break the dark blotch at the tip of the fore wing; also +by the very small size of the dark spot in the centre of the same wing. +The green chequerings of the under side of the hind wings are also more +sharply defined, and the insect is generally of a lighter build. + +Like many other butterflies, the Orange Tip is subject to variations in +colouring. Sometimes a pale but bright yellow takes the place of the +white ground, and the orange blotch of the male is occasionally present +on the upper or lower surface only. + +_Cardamines_ is a single-brooded insect, and is essentially a creature +of the spring, at which time it may be found in abundance in lanes, +meadows, and clearings in woods throughout the British Isles. Its flight +is so light and airy that even the female may easily be distinguished +from other Whites when on the wing, while the brilliant orange of the +male, intensified by the bright rays of the spring sun, may be +identified at some considerable distance. + +The food plants of _Cardamines_ include the cuckoo-flower (_Cardamine +pratensis_) and the bitter cress (_C. impatiens_), after which the +insect is named, also water-cress (_Nasturtium officinale_), winter +cress (_Barbarea vulgaris_), rock cress (_Arabis perfoliata_), hedge +mustard (_Sisymbrium officinale_), Jack-by-the-hedge (_S. Alliaria_), +wild mustard (_Brassica Sinapis_), &c., and the eggs of the butterfly +may be found on these during May and June. + +The caterpillar (Plate VIII, fig. 2) is green, with a white stripe on +each side, and its body is covered with short hair. In July it is fully +grown, and ascends a stem of the food plant to prepare itself for its +long winter sleep. + +The chrysalis (Plate VIII, fig. 8) is a very peculiar object. Both ends +are much elongated and sharply pointed; and the foremost extremity +stands out at an angle with the stem to which it is attached. + +This butterfly should be looked for during April and May, but in mild +seasons it may often be met with in March. + + +_The Wood White_ (_Leucophasia Sinapis_) + +The distinguishing feature of this butterfly (see Plate II, fig. 1) is +the extreme lightness and delicacy of its build. Its wings are narrow, +and rounded at the tips; and the only mark to relieve the white ground +of the upper side is a squarish blotch at the tip of the fore wing, and +even this is either very indistinct or entirely absent in the female. +The under surface is clouded with a pale greenish tint. + +This insect may be looked for in May and again in August, in paths and +clearings in woods, where it moves along with a slow but steady flight, +hardly ever seeming to rest for a moment. It is not by any means a +common butterfly, but is very widely distributed, and sometimes appears +in considerable numbers in certain favoured spots. Among the localities +recorded may be mentioned Torquay, Exeter, Plymouth, South Dorset, New +Forest, Reading, Darent Woods, Morecambe Bay, Haslemere, Windermere, &c. + +The caterpillar is of a beautiful green colour, and is covered with +short whitish hairs. A darker green stripe runs down the middle of the +back, and a bright yellow stripe along each side. Its food plants are +the tufted vetch (_Vicia Cracca_), bird's-foot trefoil (_Lotus +corniculatus_ and _L. pilosus_), bitter vetch (_Lathyrus tuberosus_), +and the everlasting pea (_L. sylvestris_). + +The chrysalis is a very beautiful object. Its colour is a delicate +green, tinged with pink; and the wing-cases project in beautiful curves +much beyond the general surface. + + +_The Pale Clouded Yellow_ (_Colias Hyale_) + +The ground colour of this butterfly (Plate II, fig. 2) is very variable. +It is usually a sulphury yellow, and on this account the insect is +commonly known as the Clouded Brimstone; but sometimes the yellow is +exceedingly pale--almost white--and tinged with green. + +A very large black blotch, broken by indefinite patches of the ground +colour, fills up the tip of each fore wing, and extends to the anal +angle, becoming narrower as it approaches this point. A black oval spot +lies just above the middle of this wing. + +The hind wings are bordered with black, and a conspicuous spot of deep +yellow lies very near the centre of each. + +The antennæ are rather short, compared with those of the preceding +members of this family, and are distinguished by their reddish-brown +colour. + +The male and female of this species are similarly marked, but the ground +colour of the latter is commonly paler. + +This is not by any means a very common butterfly with us, though it is +very plentiful on the other side of the Channel; but it has a way of +taking us by surprise in certain seasons, and then almost neglecting us +for several years together. + +Its head quarters are certainly the coasts of Kent and Sussex, but it +has been taken in considerable numbers as far west as Cornwall, and also +to a less extent in some of the midland and northern counties. It is +particularly fond of lucerne and clover fields, especially those that +are situated close to the sea cliffs; and often it may be seen flying +over the beach, sometimes even flitting over the breakers away from land +till at last it disappears in the distance. This maritime tendency of +_Hyale_ makes it probable that a large number of those that are seen on +our south-east coasts have made a passage across the narrow end of the +Channel. + +The eggs are laid in spring, by females that have hybernated throughout +the winter, on various leguminous plants, including the lucerne +(_Medicago sativa_), black medick (_M. lupulina_), purple and Dutch +clovers (_Trifolium pratense_ and _T. repens_), and the bird's-foot +trefoil (_Lotus corniculatus_), and on these plants you may search for +the larva, though it can scarcely be said that you are likely to find +it. + +The caterpillar is green, with black dots, and a yellowish stripe on +each side. When fully grown it ascends a stem of its food plant and +changes to a green chrysalis with yellow stripes. + +_Hyale_ is single-brooded in England, although two broods regularly +appear on the Continent. In our country the perfect insects emerge +during July and August. Many of these die before the approach of winter; +but, as we have already observed, some hybernate and deposit their eggs +in the following spring. + + +_The Clouded Yellow_ (_Colias Edusa_) + +Not only are this and the last species similarly named, but a glance at +the figures will show that they much resemble each other in appearance; +and we shall also learn presently that in their habits and life history +they have much in common. + +The male _Edusa_ is shown on Plate II (fig. 3), and when we compare it +with its relative on the opposite side, we are at once struck with the +superior richness of the brilliant orange or saffron of the ground +colour. The black border of both fore and hind wings is also denser, +wider, and more extensive. The whole of the yellow area of the hind +wings is dusted more or less with black scales, with the exception of a +round central spot of deep orange, corresponding with the orange spots +on the hind wings of _Hyale_. + +The female, which is shown in the accompanying woodcut, is generally +larger than the male, and is further distinguished by the very pale +yellow spots that break the black border of both pairs of wings. + +[Illustration: FIG. 66.--THE CLOUDED YELLOW--FEMALE.] + +_Edusa_ further resembles _Hyale_ in the reddish colour of the antennæ; +and, in both the species, the red legs form a pleasing contrast with the +yellow furry surface of the under side of the thorax. + +There is a variety of the female of this butterfly, in which the ground +colour is a _very pale_ yellow, almost white. The hind wings are more +thickly dusted with black scales than in the normal insect, and the +orange spots of these wings show up much more conspicuously from the +contrast with their surroundings. + +It is usual to apply distinct names to constant varieties of +species--names that are to be added to the ordinary title. In this +particular case the distinguishing name is _Helice_, so that we should +speak of the variety of _Edusa_ above mentioned as: + + +_Colias Edusa_, var. _Helice_ + +Like _Hyale_, _Edusa_ is particularly capricious in its appearance. In +certain summers it absolutely swarms in favourite localities, while +during the intervals between such remarkable appearances--usually +several years--it is positively scarce. The last favoured season was the +summer of '92, during which (from the beginning of August to the end of +the summer) dozens might easily have been caught in an hour or two; in +fact, so plentiful were they in many places, that they were continuously +in sight, often several at one time. + +Those in search of this insect should repair to the south coast, +especially the south-east, and where lucerne and clover fields are in +flower. It has very decided maritime tendencies, and may often be seen +flying over the cliffs and beaches, and even skipping over the breakers; +but, at the same time, it is more or less plentiful in many inland +districts. It has been taken in many parts of Ireland and Scotland, +particularly along the southern coasts of these countries; but its head +quarters are undoubtedly the southern cliffs of England, from Cornwall +to Kent, and also the hilly inland districts of the south-eastern +counties. + +_Edusa_ catching is very lively sport, and is likely to prove sufficient +for any lover of outdoor exercise under a scorching sun; for this +butterfly is not only very powerful on the wing, but its flights are +usually long, so that a good run is often absolutely necessary in order +to capture it. On very hilly ground, such as _Edusa_ loves, chase is +often hopeless, and then it is necessary to resort to stratagem. In such +a case the best plan is to make a very cautious approach when the insect +has been observed to settle, and then secure it with a sudden +down-stroke of the net. + +The eggs are laid during May and June by a few females that have +survived the winter. + +The caterpillar may be found in June and July on its food plants, the +chief of which are the bird's-foot trefoil (_Lotus corniculatus_), and +the purple and Dutch clovers (_Trifolium pratense_ and _T. repens_). Its +colour is grass-green, and it is marked with a narrow whitish stripe on +each side, which is broken by the yellow of the spiracles. + +The chrysalis is of a pale yellowish green, and is marked with yellow +stripes and reddish-brown dots. + + +_The Brimstone_ (_Gonopteryx Rhamni_) + +This, the last member of the present family, is remarkable for the +graceful outline of its wings. The costal margins of the fore pair are +most beautifully arched, and both pairs are sharply angled on the hind +margins. This latter characteristic is quite unique among British +butterflies, though we shall presently meet with instances of angular +projections on hind wings only. + +The ground colour of the male (Plate II, fig. 4) is a rich sulphury +yellow, with a greenish tinge. That of the female is a very pale +greenish yellow. The only conspicuous markings are small saffron spots, +one near the centre of each wing. The antennæ are red, short, and +beautifully curved; but, unlike the two preceding species, the legs are +almost white. + +The eggs of this butterfly are laid in April on the two species of +buckthorn (_Rhamnus catharticus_ and _R. Frangula_) by the females that +have successfully weathered the winter. They are of a bright yellow +colour, and are usually hatched in about a fortnight. + +The body of the caterpillar is green, and it is thickly covered with +little black wart-like projections. A pale stripe also runs along each +side. During May and June it may be found on its food plants, and toward +the end of the latter month it attaches itself by a silken carpet and +belt to the under side of one of the leaves. + +The chrysalis is of a very peculiar shape, the body being curved, and +the wing cases standing out prominently beyond the general surface. Its +colour is a bright apple green marked with yellow, and it is so +transparent that certain of the structures can be seen through its skin. + +The perfect insect emerges in about three weeks after the change to the +chrysalis; and may be looked for from July to the end of the summer. +This period may be regarded as the best time in which to hunt for +_Rhamni_, but it is to be noted that this butterfly makes its appearance +during all months of the year, even though it is single-brooded. + +A large number seem to hybernate, and their winter sleep is so light +that the welcome rays of the sun on a mild day, even during the bleak +months of November to February, will often call them out from their +hiding places. Then, as a rule, the hybernating butterflies do not live +long after depositing their eggs for the future brood; but the Brimstone +often lives on till its offspring have themselves attained the perfect +state, so that it is possible to capture the insects of two different +years both on the same day. In such a case it is generally easy to +distinguish between the two, for the newly emerged specimens are +beautifully bright and fresh in colour, while those of the previous year +are more or less faded and worn, their wings being often +semi-transparent through the loss of scales, and frequently disfigured +by the stains of mildew. + + + + +CHAPTER XIII + +_THE FRITILLARIES, VANESSAS, AND THE PURPLE EMPEROR_ + + +Family--NYMPHALIDÆ + +We now come to a rather large family, which contains some of our largest +and most brilliant butterflies. Some of them display the most gaudy +colours, and others exhibit patches of a beautiful metallic lustre. + +If you were to see all the members of this family side by side, they +might strike you as being so varied in their appearance that you would +wonder why they are all placed in one family group. But, were you to +see, in addition to the perfect insects, all their larvæ and +chrysalides, the reason would be made clear at once, for these earlier +stages are seen to resemble each other in certain points at the very +first glance. The former are all provided with peculiar spines, and the +latter are all more or less angular, and are all suspended to a silken +carpet by means of hooks at the tip of the abdomen, and have no belt as +we have observed in the case of the _Pieridæ_. + +The perfect insects, too, although so varied in colouring, are alike in +that they have only four walking legs, the first pair being so +imperfectly developed as to be useless for this purpose. + +This family includes the Fritillaries and the Vanessas. + + +_The Small Pearl-bordered Fritillary_ (_Argynnis Selene_) + +The interesting group of butterflies known as the Fritillaries vary +considerably in size, but are remarkably uniform in the ground colour of +the wings, which, in all cases, is a rich golden or sienna brown; and +this ground is chequered with darker colours in such a manner as to +remind one of the petals of the wild flower known as the Snake's Head +or Fritillary--hence the popular name of the group. + +The Small Pearl-bordered, our first example, is one of the lesser +Fritillaries, and is shown in Plate II (fig. 5). + +The arrangement of the black markings on the upper surface will be +readily made out from the coloured plate, but the pattern of the under +side will require a little special notice, for it is here, as with the +other Fritillaries, that we find the chief marks by which we identify +the species. On this side (fig. 67) the fore wings are light orange +brown, with a patch of darker brown near the tips, and spotted with a +dull black. The hind wings have the light brown displaced by a very warm +chestnut tint, some yellow, and bright silvery spots. + +[Illustration: FIG. 67.--THE SMALL PEARL-BORDERED FRITILLARY--UNDER +SIDE.] + +Seven silvery spots of triangular form border the hind margin. A large +one occupies the centre of the wing, and ten others are somewhat +irregularly scattered over other parts of the wing--five between the +central spot and the hind margin, and five between it and the costa. + +All the spots on these wings, whether yellow, chestnut, or silver, are +bordered by a narrow black line. + +_Selene_ is not a very abundant butterfly, but is widely distributed in +England, and is also found in parts of Scotland. Its favourite resorts +are clearings in woods, especially those of Kent and other southern +counties. + +It appears in May and June, in which latter month it deposits its eggs +on the dog violet (_Viola canina_). + +The caterpillar is not fully grown at the end of the summer, and +hybernates during the winter among the roots of its food plant. In the +following spring it emerges again, and feeds till May, when it changes +to the chrysalis on a stem. It is less than an inch long when fully +grown, and is of a dark-brown colour. Six rows of hairy spines are +arranged longitudinally on its body. + +The chrysalis is greyish brown, and has a number of very short +projections corresponding with the spines of the caterpillar. + + +_The Pearl-bordered Fritillary_ (_Argynnis Euphrosyne_) + +There is very little difference in the size of this and that of the last +species, but _Euphrosyne_ (Plate II, fig. 6) is generally a trifle +larger. The two butterflies are also very similar in appearance; indeed, +they are so much alike on the upper side that it is impossible to decide +on the name of either without an examination of the under surface. + +_Euphrosyne_ has a border of seven triangular silver spots on each hind +wing, exactly corresponding with those of _Selene_. It has also the +large central spot of silver. But, beside these, there is _only one_ +other, and that is situated in the basal angle. Thus there are only nine +silvery or pearly spots on each hind wing of _Euphrosyne_, while there +are seventeen on _Selene_. This will form a ready means of +distinguishing between the two species. + +[Illustration: FIG. 68.--THE PEARL-BORDERED FRITILLARY--UNDER SIDE.] + +The seasons and localities of this butterfly correspond very closely +with those of the last species, but it is much more common, and may be +found in abundance in nearly all our southern woods during May and June. + +The caterpillar, also, feeds on the same plant (dog violet) as _Selene_. +It is black, with whitish lines along the sides; and is provided with a +number of bristly spines. + +The chrysalis is of a grey-brown colour, with small dots of a paler tint +on the wing cases; and its body has a number of short conical +projections exactly corresponding with the spines of the caterpillar. + + +_The Queen of Spain Fritillary_ (_Argynnis Latona_) + +We now pass from the commonest to the rarest and most prized of our wood +butterflies--The Queen of Spain (Plate II, fig. 7). This royal personage +is not easily mistaken for any of the meaner Fritillaries even when the +upper surface only is examined, as the concave hind margins of the fore +wings serve as an almost conclusive mark of distinction. The rich tawny +brown of this side is boldly marked with black, and the long hairs and +scales of the bases of the wings are tinged with green. + +The under side presents a most beautiful appearance. Here the ground +colour is paler than that of the upper side. The fore wings are spotted +with black, and have a few small patches of silver at the tips. Each +hind wing has no fewer than twenty-four bright silvery spots. Seven of +these, mostly of large size, adorn the hind margin, and above each of +these is a small one in the middle of a little patch of dark brown. The +arrangement of the others is not quite so easily described, but may be +readily made out from our illustration. + +[Illustration: FIG. 69.--THE QUEEN OF SPAIN FRITILLARY--UNDER SIDE.] + +This rare gem among British butterflies has been taken in many +localities, but in very small numbers. Seeing that it is a common insect +on the other side of the Channel, and that the British captures have +been made chiefly in the Isle of Wight and on the south coast, I am +inclined to believe that many of the highly valued genuine Britishers +have no right to their title, but are visitors that have spent only a +few days within our shores, having flown or been blown across the sea. + +It is not likely that many of my readers will ever meet with _Latona_ +during their rambles in our own country, and if they are anxious to have +the species represented in their collections, they will probably have to +purchase either a British or a foreign specimen, the former of which +will command a very high price, while the latter may be obtained for +three or four pence. + +The perfect insect may be looked for in August and September, during +which time the eggs are laid on the leaves of violets and the heartsease +(_Viola canina_, _V. odorata_, and _V. tricolor_). + +The caterpillar is brown, with numerous yellowish spines, and has three +whitish or yellowish stripes--one down the middle of the back and one +along each side. It hybernates during the winter, and is fully grown in +the following June or July. I hope that my reader will be so fortunate +as to secure either this or some other stage of this rare and beautiful +insect. The chances are decidedly against him, but that is no reason +why he should abstain from a vigorous search when he happens to be +'doing' the southern counties. + + +_The Dark-green Fritillary_ (_Argynnis Aglaia_) + +This butterfly is larger than _Latona_, as will be seen by reference to +Plate II, fig. 8. Its colour is, as usual with the Fritillaries, a tawny +brown with black markings. The female is usually larger than the male, +and she is further distinguished by the ground colour being darker and +the black markings larger. + +The under side of the fore wings is very similar in colour and markings +to the upper, but there are silvery spots near the tips. The hind wings +are beautifully tinted with olive green and brown, and studded with +silver. The arrangement of the latter is not easily described, but is +accurately represented in the accompanying woodcut. + +[Illustration: FIG. 70.--THE DARK-GREEN FRITILLARY--UNDER SIDE.] + +The favourite resorts of this insect are wooded spots, and also heaths +and downs clad with heather or ferns, where its food plant (the dog +violet) lies scattered; but it seems to be less partial to woods than +the other Fritillaries. It is very widely distributed throughout +England, and is common in parts of Scotland and Ireland. + +The perfect insect is on the wing in July and early August. + +The caterpillar first appears toward the end of August, and commences +its period of hybernation among the roots of its food plant before it +has grown to any considerable size. It comes out again in the spring, +and continues to feed till the beginning or middle of July, and then +changes to the chrysalis state, after protecting itself by binding three +or four leaves together. + +Its colour is a velvety black, with dark and glossy grey between the +segments. There is a double yellow line along the back, and a thin line +of orange yellow on each side below the spiracles. It has a number of +black hairy spines, arranged in six longitudinal rows. + +The chrysalis is of a shiny black colour, with brownish abdomen; and the +conical projections are black with yellow tips. + + +_The High-brown Fritillary_ (_Argynnis Adippe_) + +The upper side of this butterfly is so much like that of _Aglaia_ that +it would be difficult indeed to give a written description of one that +did not almost equally well apply to the other; so we look to the under +surface for the chief marks by which we can distinguish between them. + +On this side (Plate III, fig. 1) the fore wings are much the same as +those of _Aglaia_. The hind wings, too, are very similarly coloured and +marked, but here we have a distinguishing feature in a row of rust-red +spots with silvery centres, just inside the silver border of the hind +margin. + +[Illustration: FIG. 71.--THE HIGH-BROWN FRITILLARY.] + +This butterfly is common in open spaces of woods in many parts of +England, more particularly in the south, and seems to be also fond of +hilly heaths and moors. + +It is on the wing in July, and, towards the end of this month and in the +beginning of August, the eggs are laid on the leaves of the dog violet +(_Viola canina_) and heartsease (_V. tricolor_). + +The young caterpillar emerges about two weeks later, and feeds only for +a short time before it seeks out its winter quarters among the dead +leaves at the root of its food plant. The feeding is resumed in the +spring, and continued till the month of June, when it is fully grown. At +this time it is about an inch and a half long. Its head is black, and +its body pinkish brown. A white line extends down the back, but is +interrupted by several black marks. The spines, of which there are six +rows, are white, with pinkish tips. + + +_The Silver-washed Fritillary_ (_Argynnis Paphia_) + +This beautiful and noble butterfly is the largest of the Fritillaries, +and the most powerful on the wing. During the latter part of June and +throughout July it may be seen gracefully sweeping through the trees and +undergrowth of woods, often settling down on a favourite flower for a +short time. So strong is its flight that it is useless to attempt to +pursue it for any distance. Sometimes it will sail along a wooded path, +followed at short intervals by others of its species, and may be taken +in the net as it passes. But perhaps the most successful method of +netting _Paphia_ is to wait till it has settled, and then secure it by a +quick upward or side stroke of the net. If then you miss your aim, off +it will dart, sailing over the tree tops till, in a very short time, it +is quite out of sight. + +[Illustration: FIG. 72.--THE SILVER-WASHED FRITILLARY--UNDER SIDE.] + +The upper side of this butterfly is shown in Plate III, fig. 2, where +the general arrangement of the black spots on the rich orange-brown +ground is carefully marked. There is a considerable difference between +the male and female of this species. The figure on Plate III represents +the male. The female does not possess the broad black lines that follow +the course of the veins of the fore wings; the basal portions of all +four wings are also tinged with a rich olive-brown colour, often with a +decided tendency to green; and the black spots of all the wings are +larger. + +The under side is particularly rich in its decorations. The front wings +are of the usual orange brown, chequered with black. The hind wings are +partly brown and partly orange, and exhibit beautiful greenish +reflections. They have also two bars of silver, and a silvery spot in +the basal angle, all with rather indefinite outlines. + +The female lays her eggs late in July on the food plants (_Viola canina_ +and _V. odorata_) or on the moss that surrounds them. + +About two weeks later the young caterpillar is out and feeding; and +then, after a few more weeks, while it is yet very small, it hides among +the dead leaves at the roots. Early in the spring it resumes its +feeding, and is full grown at the end of May. + +The colour of the caterpillar (Plate VIII, fig. 3) is black, and there +are two yellow lines along the back, separated by a black stripe, also +one yellowish line on each side. Its body is adorned with reddish-brown +spines, two of which, situated just behind the head, are longer than the +others. + +The chrysalis (Plate VIII, fig. 9) is greyish, marked with metallic +spots, and has a number of angular projections representing the spines +of the larva. + +_Paphia_ is to be met with in woods in all parts of England and Wales. +It has also been observed in Ireland, but is rarely seen in Scotland. + + +_The Greasy Fritillary_ (_Melitæa Aurinia_) + +Unlike the other Fritillaries, this species (Plate III, fig. 3) exhibits +a variety of shades on the upper surface. A broad band of sienna brown +stretches across each wing, near to and parallel with the hind margin. +The other parts of the wings are marked with patches of sienna, orange, +and yellow, separated by black lines and bands. The margins are all +black, and inside the broader margin of the hind wing is a row of six +very pale yellow spots. The broad sienna band of the hind wing is also +divided by narrow black lines into seven parts, six of which have black +centres. + +[Illustration: FIG. 73.--THE GREASY FRITILLARY--UNDER SIDE.] + +The under surface of the fore wings has indefinite yellowish and tawny +patches, which look as if they had been greased and smeared. The hind +wings are marked with pale yellow and deep orange; a broad band of the +latter, near the hind margin, is divided into segments, each of which +has a yellow spot with black in the centre. + +This is a very local insect, although it is widely distributed +throughout England and Wales. It also occurs sparingly in Scotland and +Ireland. Its food plants are the honeysuckle (_Lonicera_ +_Periclymenum_), devil's-bit scabious (_Scabiosa succisa_), and the +plantain (_Plantago_); and its chief resorts are damp meadows and marshy +places, where these plants (more especially the scabious) abound. + +The butterfly appears about the end of April or in June. + +The caterpillars emerge from the eggs towards the end of the latter +month, and always feed in groups under the cover of a silken web. Like +the preceding species they hybernate during the winter, and commence +feeding again in the spring. They are fully grown about the end of +April. + +In colour the caterpillar is velvety black, dotted with white, and its +body is covered with short bristly spines. When fully fed it seeks the +shelter of a curled leaf or dense herbage, suspends itself by the hind +claspers to a silken carpet, and then changes to a creamy white +chrysalis with black dots. + + +_The Glanville Fritillary_ (_Melitæa Cinxia_) + +The pattern of the upper side of this Fritillary (Plate III, fig. 4) is +very similar to that of _Aurinia_, but the ground colour is a uniform +tawny brown, and the fringes of the wings are of a very pale straw +colour, barred with black. + +The under side of the fore wings is tawny brown, with straw-coloured +tips bearing black markings. The hind wings have four alternate bands of +brown and straw colour, and a patch of straw colour at the base. The +marginal yellow band has six or seven black spots. The brown band next +to it is divided into six segments with black borders, each with a black +spot. The next yellow band has also a row of black spots. The inner +fulvous band is very irregular; and inside this is the yellow base with +six spots. + +[Illustration: FIG. 74.--THE GLANVILLE FRITILLARY--UNDER SIDE.] + +This is another local insect--very local indeed, for it seems to have +been found only in a few spots outside its head quarters, the Isle of +Wight. Those in search of it should carefully scan the rough cliffy +parts of the island, wherever the species of plantain (_Plantago +Coronopus_ and _P. maritima_) are plentiful, these being the food plants +of the larvæ. It first appears on the wing in May, but may be found till +the end of June. + +The caterpillars, which are black and spiny, with reddish head and legs, +begin to feed in August, and as soon as the chilly weather sets in they +hybernate in groups under the cover of a tent constructed by binding +together leaves or blades of grass. In the spring they start out again, +and feed till the end of April, at which time they change to dark +brownish and smooth chrysalides. + + +_The Heath Fritillary_ (_Melitæa Athalia_) + +Both the upper and under sides of this butterfly are shown on Plate III +(figs. 5 and 6), and it will be observed from these that its general +appearance is very similar to that of _Cinxia_. + +The upper surface is of the same tawny brown, barred and striped with +black, and the fringes of the wings are pale yellow, interrupted by +small patches of black. + +The under surface of the fore wings has the same ground colour with the +exception of the tips, which are yellow; and the whole is marked with +black, as in the illustration. The hind wings are pale yellow, with two +broad bands of brown corresponding with those of _Cinxia_; but a series +of black double arches along the hind margin and the _absence_ of rows +of black spots serve to distinguish this species from the last. + +_Athalia_ is another local butterfly, but is sometimes found in +abundance in the spots which it frequents. It is met with chiefly in the +open spaces of woods along the south coast and for some distance inland. +Devon, Cornwall, Sussex, and Kent seem to be the most favoured counties; +and London entomologists would do well to search for it in Epping +Forest. + +The butterfly deposits its eggs during June and July, on several +different food plants, the chief of which are the greater and +narrow-leaved plantains (_Plantago major_ and _P. lanceolata_), foxglove +(_Digitalis purpurea_), two species of cow-wheat (_Melampyrum pratense_ +and _M. sylvaticum_), wood sage (_Teucrium Scorodonia_), and the +germander speedwell (_Veronica Chamædrys_), and the young caterpillars, +after feeding for only a week or two, commence their period of +hybernation. They resume their feeding in April, and change to the pupal +state about the end of May. + +The colour of the caterpillar is velvety black, finely dotted with +white, and the spines are yellow or orange, tipped with white. + +The chrysalis is creamy white, banded and patched with orange and +black, and is suspended by anal hooks from a silken, carpet which the +caterpillar had spun on the leaf of the food plant. + + +_The Comma_ (_Vanessa C-Album_) + +Leaving the Fritillaries, we now come to a genus (Vanessa) that includes +seven most beautiful butterflies, some of which are so common as to be +known to almost everybody. + +It will be observed that this genus belongs to the same family as the +Fritillaries, and we may therefore expect to find that the two groups +possess features in common. A slight examination of a few in their +different stages will show that this is so. Thus, the perfect insects +have only four walking legs, the caterpillars are all spiny, and the +chrysalides are angular. + +[Illustration: FIG. 75.--THE COMMA--UNDER SIDE.] + +There is another feature concerning the chrysalides worthy of note. Like +some of the pupæ of the Fritillaries, they are adorned more or less with +brilliant metallic spots, sometimes of a rich golden hue, and sometimes +resembling burnished silver. Now the word 'chrysalis,' which, as we have +already seen, is derived from a Greek word meaning 'gold,' was +originally applied to the pupæ of some of the Vanessas, on account of +their metallic decorations, but it has since been extended to the pupæ +of all the Lepidoptera, and also to other orders of insects, even though +the greater number of them display no tints of the precious metal. + +The first member for our consideration is the Comma Butterfly, of which +an illustration is given in Plate III, fig. 7. No one could mistake this +beautiful butterfly for any other British species, for its wings of rich +orange brown, with black and dark-brown markings, are so irregularly +scalloped on the hind margins that they present a somewhat ragged +appearance. Its name is derived from the fact that a white mark +something like the letter C, or, as some have it, like a comma, is +distinctly painted on the dark brown of the under side. + +This butterfly generally emerges from the chrysalis late in the +summer--August and September, but it is often seen earlier, and +frequently as late as October. It is a great lover of sweets, and may be +found settled on various flowers and fruits. Its chief food plants are +the hop (_Humulus Lupulus_), red currant (_Ribes rubrum_), stinging +nettle (_Urtica dioica_), and the Elm (_Ulmus campestris_). + +It is very abundant in certain districts where hops are grown, but seems +to avoid those counties that border the sea. It is widely distributed in +the midland counties, and extends to the north of England and into +Scotland, but is very capricious in its appearance in many parts. + +The eggs are laid in May by females that have hybernated through the +winter, and the caterpillars may be found feeding during July and +August. + +The caterpillar is coloured grey and brown, with a black head, and a +broad white stripe down the back of the hindermost segments. The body is +armed with a number of spines, some of which are white, and others pale +brown. + +The chrysalis is a very peculiar object, having two ear-like projections +extending forwards from the sides of the head. It has a number of +angular projections, and is of an umber-brown colour, finely netted with +black lines, and having several spots of a brilliant metallic lustre. + + +_The Large Tortoiseshell_ (_Vanessa Polychloros_) + +Our two tortoiseshells--large and small--are very similar in their +colour and markings, and moreover are not always to be distinguished by +their size, for specimens of the larger species are sometimes even +inferior in this respect to the largest of the smaller species; so, to +avoid all risks of mistaken identity, we must look for more reliable +marks of distinction between them. + +The present species is figured on Plate III (fig. 8), where it will be +seen that the ground colour of dark tawny brown is spotted and bordered +with black. The border of the hind wings contains a row of +crescent-shaped blue spots. The costal margin of the fore wings, between +the black patches, is decidedly lighter than the general ground, and is +yellow rather than brown. It will be noticed, too, that a black spot +lies very near the anal angle of these wings. + +The under surface, though by no means brilliant, exhibits a rich +blending of various shades of brown. + +This butterfly is not known to occur in either Scotland or Ireland, and +is by no means common in England. Its chief localities are in the +midland and eastern counties. + +The perfect insect generally appears about the middle of July, and after +spending a month or six weeks on the wing, seeks out a sheltered spot in +which to spend the winter. In the spring--April or May--it again takes +to flight, and during the latter month the females are busily engaged in +the deposition of their eggs. + +The caterpillar feeds on the two species of elm (_Ulmus campestris_ and +_U. montana_), willow (_Salix alba_), sallow (_S. Caprea_), osier (_S. +viminalis_), aspen (_Populus tremula_), and certain fruit trees; and is +full grown about midsummer. It is of a tawny grey colour, with a black +stripe on each side, and is covered with very small wart-like +projections, and the spines are branched. + +The chrysalis is of a dull pinkish colour, and may be found on tree +trunks, palings, and walls, about the end of June, suspended from a +silken carpet by means of its anal hooks. + + +_The Small Tortoiseshell_ (_Vanessa Urticæ_) + +_Urticæ_ (Plate III, fig. 9) may be distinguished from _Polychloros_ by +the _absence_ of the black spot in the anal angle of the fore wings of +the latter. It has also a white spot near the tip of each fore +wing-between the black border and the first black costal patch. The +whole of the base of the hind wing is also black, and the ground colour +is decidedly brighter. + +It is one of the commonest of all British butterflies, and is to be +found more or less abundantly in nearly all parts of the British Isles. + +The hybernated perfect insects come out early in the spring, and lay +their eggs in close irregular clusters on nettles (_Urtica dioica_ and +_U. urens_). Shortly after the gregarious caterpillars may be found on +these plants in dense masses. They change to the chrysalis state about +the end of May, and from this time there is a continuous succession of +butterflies till the end of the summer. + +The later specimens, which do not emerge till September or October, +spend only a short time on the wing, and then hybernate till the spring, +giving rise to the first brood of the following season. + +The caterpillar of this species is black above and greyish beneath. It +is thickly covered with yellow dots, which are so close together on the +back as to form two yellowish stripes, separated only by a fine black +line. There are also two yellowish stripes along each side; and the +body, as with the rest of this genus, is spiny, the spines in this case +being black or very dark green. + +The chrysalis is brownish, and spotted with burnished gold in variable +quantity--sometimes so plentifully as to cover the greater part of the +surface. + + +_The Peacock_ (_Vanessa Io_) + +This is another of our commonest and most beautiful butterflies. Its +general appearance is such that it cannot possibly be mistaken for any +other. The upper side (Plate IV, fig. 1) is rendered conspicuous by the +beautiful eye-like marks at the costal angles of all four wings; and the +under surface is very richly decorated with a fine arrangement of black +and dark-brown patches and streaks. + +Io is very abundant in all parts of England, and is well known in many +parts of Scotland and Ireland, but seems to be rare in the extreme north +of both of these countries. + +Its food plant is the stinging nettle (_Urtica dioica_), and on this the +eggs are laid in April by females that have hybernated during the +winter. + +The caterpillar is full grown at the end of June or beginning of July. +It is black, with numerous minute white wart-like projections. Its +spines also are black, and its claspers brown. + +The chrysalis may be found suspended by the tail on some object in the +neighbourhood of the food plant, or sometimes on the food plant itself. +It is of a greenish colour, with yellowish patches, but turns darker as +the time approaches for the emerging of the perfect insect. + +This event takes place in August, and the butterfly, after a brief +period on the wing, seeks out a sheltered spot for its winter nap. + + +_The Camberwell Beauty_ (_Vanessa Antiopa_) + +The reader will be fortunate if he succeeds in netting a specimen of +this highly prized British butterfly. It derives its popular name from +the fact that a few were taken in Camberwell about a hundred and fifty +years ago; and since that time it has been seen and taken in variable +numbers in several parts of England. So widely distributed, indeed, are +its localities, and so few, comparatively, its appearances, that it +would be useless to attempt to give any hints as to where it may be +looked for. It is, however, a very common butterfly in many continental +countries, and foreign specimens may be obtained from any dealer in +entomological wares for a few pence each. + +This rare British gem is illustrated in fig. 2 of Plate IV. Here it will +be seen that nearly the whole of the surface is covered with a rich +velvety purple brown, bordered with a black band containing blue spots; +and outside this is a border of white, finely dotted and streaked with +black. The continental specimens may be easily distinguished from the +genuine Britishers by a darker border with a decidedly yellow tinge. + +The eggs of this species are generally laid on the young leaves of the +willow (_Salix alba_), in the spring, by females that have hybernated, +but sometimes the nettle (_Urtica dioica_) and the birch (_Betula alba_) +are selected for the food of the larvæ. + +The caterpillar is black and spiny, and has a row of seven rather large +reddish-brown spots on the back, commencing at the fifth segment. + +The chrysalis, like those of the other members of this family, is +angular and suspended by the 'tail.' The perfect insect appears in +August, and may be seen from that month till October. + + +_The Red Admiral_ (_Vanessa Atalanta_) + +There seems to be a tendency with many to under-estimate the beauty of +certain natural objects because they happen to be so very common, and +this is particularly the case with some of our most familiar +butterflies. The beautiful Red Admiral (Plate IV, fig. 3) may possibly +suffer in this respect; for, not only is it one of the commonest of our +butterflies, but it fearlessly hovers among the flowers of our gardens, +often venturing into the very heart of thickly populated towns. + +The bright scarlet bands and white blotches of this gorgeous insect +stand out boldly on the rich velvety black ground of the wings, and the +additional touches of blue in the anal angles of the hind wings add to +the effect. The under side of the fore wings is somewhat similar to the +upper surface, but is relieved by brown and blue; and this side of the +hind wings presents most beautiful and indescribable blendings of +various shades of brown, grey, and pink. The female may be +distinguished by the presence of a small white spot on the scarlet band +of the fore wing. + +The eggs are deposited singly on the nettle (_Urtica dioica_) in spring +by females that have hybernated through the winter. + +The caterpillar always feeds under the cover of a tent made by drawing +leaves together. It is spiny, and its colour is usually a greenish or +yellowish grey, spotted with black, and striped along the sides with +white or yellow. When fully grown it bites the stem of the nettle nearly +through a few inches from the top, so that the upper part of the plant +bends over the withers. It then constructs a commodious tent by binding +the leaves of this drooping portion together, and suspends itself from +the roof of this strange home to undergo its metamorphoses. + +The change to the chrysalis state takes place in July or August, and the +perfect insect may be seen during August, September, and October in +almost every part of the British Isles. + + +_The Painted Lady_ (_Vanessa Cardui_) + +Although the time of appearance of this butterfly generally corresponds +with that of the last species, yet it is exceedingly variable, so much +so that it is impossible to give any fixed period as its season. It is, +moreover, very capricious with regard to its localities and its numbers. +Sometimes it will turn up unexpectedly in positive abundance in certain +localities where previously it had been a mere straggler; and then, for +some unaccountable reason, become comparatively scarce for several +successive seasons. + +The upper surface of this beauty (Plate IV, fig. 4) is adorned with pale +red, orange, and black, and with five white spots near the tip of each +fore wing. The under side of the fore wings is marked something like the +upper, but much of the black is replaced by shades of brown. The hind +wings are beautifully variegated beneath with greys and browns, and have +a row of eye-like spots near the hind margin. + +The eggs of this butterfly are laid singly on various species of +thistles, particularly the common field thistle (_Cnicus arvensis_), +generally in the month of June. + +The caterpillar, which is black above and red beneath, with yellowish +stripes along the back and sides, feeds under the cover of a silken web +which it constructs among the leaves. It is full grown in July or +August, when it suspends itself after the manner of the other Vanessas +previous to undergoing its changes. + +The chrysalis is angular, coloured with brown and grey, and adorned with +brilliant gold spots. + +The perfect insect may be seen at large throughout late summer and the +autumn, and the eggs are laid by females that survive the winter. + + +_The White Admiral_ (_Limenitis Sibylla_) + +The White Admiral (Plate IV, fig. 5) is neither so pretty nor so common +as its red namesake, but it is nevertheless a fine insect, although the +chief beauty is reserved for the under surface. Above, the ground colour +is a very dark rusty brown, relieved by bands and spots of white. The +under surface is beautifully marked with silvery blue, bright orange +brown, and white, the latter being arranged just like the corresponding +colour on the upper side. + +It will be observed that this butterfly does not belong to the _Vanessa_ +genus; so, while we may look for _family_ resemblances, we shall observe +a few features in which it differs from the preceding species. + +It is not by any means abundant, being unknown in Scotland and Ireland, +and confined in England almost exclusively to the oak woods of the +south, where its food plant--the honeysuckle (_Lonicera +Periclymenum_)--abounds. Here it may be seen during July, gracefully +sailing among the trees and across the open spaces. + +The caterpillar is very different from those of the Vanessas. Its colour +is dark green, with a narrow white stripe along each side. There are +very conspicuous branched spines on the third and two following +segments, also on the eleventh and twelfth; and smaller spines on most +of the others. All the spines are of a brownish colour, with pink tips. +While it is yet very small it prepares its winter quarters by bending +round the remains of a leaf on which it has been feeding, securing the +edges by silken threads, and then binding it to the stem of the plant. +Soon after, the petiole becomes detached from the stem, and the little +caterpillar then rests suspended in its snug swinging cradle, where it +remains perfectly secure till the following April, when the warm sun +calls it out to feed on the opening leaves. It continues at this till +about the beginning of June, and then changes to a beautiful angular and +eared chrysalis, of a bright green colour, marked with brown, and having +brilliant silvery spots and streaks. + + +Family--APATURIDÆ + +_The Purple Emperor_ (_Apatura Iris_) + +This grand insect is the only British member of its family, and richly +deserves its popular title. The male, which is figured on Plate V (fig. +1), exhibits a most gorgeous imperial purple, which is reflected at +certain angles only from the upper surface of his large and powerful +wings. His flight is lofty and vigorous, and among the topmost branches +of majestic oaks, where he defies the efforts of would-be capturers. +Unlike our other butterflies, he is also a very quarrelsome creature, +and will not hesitate to fiercely attack a brother Emperor who dares +approach the branch he has selected for his throne. + +Many attempts have been made to capture this prized creature by means of +a large net mounted on the end of a pole twenty or thirty feet in +length, but the wielding of such a cumbersome implement against so +powerful an insect is no mean task, and but few fall a prey to such a +snare. But it so happens that this imperial personage has a very +depraved appetite, the indulgence in which has often brought him to +ruin. Instead of searching out the sweets so bounteously supplied by the +blossoms that are so attractive to other lepidopterous insects, he +delights in sipping the waters of the filthiest puddles, and imbibing +the odoriferous moisture of dung and the decomposing carcases of +animals. So deeply seated is this depravity of taste that the Emperor +may be netted with ease while indulging in his sumptuous feast, and is +even to be taken at times with the fingers. + +The knowledge of this peculiarity of the imperial palate has led +entomologists to abandon the awkward net, and to bait the woods with +viands that alone can entice his highness from his lofty seat; and many +a splendid specimen has been easily captured while enjoying the +luxurious juice of a dead cat, stoat, or rabbit, or of a seething mass +of pig's dung. + +The female is larger than her mate, and does not display the beautiful +purple reflections that adorn the male. She is very different, too, in +her habits, for she sits nearly all day on high branches of trees, +giving her attention to the graver duties of an imperial mother, and is +consequently but seldom seem. She lays her eggs in July on the sallow +(_Salix Caprea_) or the poplar (_Populus_), and in less than a fortnight +the young caterpillars are hatched. They feed on till the leaves are +falling, and then fix themselves by their claspers to a silken carpet +which they construct on a twig. Here they remain, exposed to all the +wintry blasts and frosts, till the new leaves are out in the spring, +when they again commence feeding, and continue to do so till they are +full grown--in May or June. + +The under side of this species is shown in fig. 76, in which will also +be observed the eye-like spots of the fore wings which have given rise +to its specific name (_Iris_). + +The caterpillar (Plate VIII, fig. 5) is a very peculiar creature. Its +body is green, with seven oblique yellowish stripes on each side, and it +has a pair of horns attached to its head. + +[Illustration: FIG. 76.--THE PURPLE EMPEROR--UNDER SIDE.] + +The chrysalis (Plate VIII, fig. 10) may be found in June, suspended to +the under side of a leaf. It is of an apple-green colour, and still +exhibits the oblique stripes which we observed in the caterpillar. + +This insect is not to be found in either Scotland or Ireland, but is +more or less abundant in many of the oak woods of the midland and +southern counties of England. Among the numerous favoured localities, we +may mention Colchester, Forest of Dean, Northamptonshire, Ipswich, +Huntingdonshire, Buckinghamshire, Epping, Lyndhurst, and the Isle of +Wight. + + + + +CHAPTER XIV + +_THE BROWNS AND HEATHS_ + + +Family--SATYRIDÆ + +This family contains eleven British species, often spoken of +collectively as the 'Browns,' since in most of them the prevailing tints +are various shades of brown. They are decidedly dingy in comparison with +the beautiful butterflies we have been previously observing; but to this +statement we must allow one marked exception, for the family includes +the beautiful Marbled White, which stands out prominently among its +fellows for brilliancy and boldness of colour. + +The caterpillars of the 'Satyrs' have no spines, but their bodies are +covered with very minute hair-bearing warts that give them a soft +velvety appearance. The hinder extremity tapers off considerably, and +terminates in two points. + +The chrysalides are not angular like those of the preceding species, and +though generally suspended by the tail, are sometimes found quite free +among leaves and grasses on the ground. + +The perfect insects are rather feeble fliers, and generally take so +little notice of intruders that they are easily caught in the hand. +Their wings are devoid of angles, and they have only four perfectly +developed legs. + + +_The Marbled White_ (_Melanargia Galatea_) + +Our first member of this family is the exception to which we have +already alluded as a relief to the general dinginess of the 'Browns.' +Its colours above are cream and black, arranged as shown in Plate V, +fig. 2. The under side (fig. 77) is marked with white, black, and +greenish grey, with a row of eye-like spots parallel with the hind +margin of the hind wings. + +This butterfly is not known in Scotland or Ireland, nor is it to be +found in several of the northern counties of England. Its chief haunts +are the waste cliffy grounds of the southern and some of the midland +counties of England, where it is usually restricted to certain small +districts. In some places it is really a common insect, and among these +may be mentioned Brighton, Horsham, Dover, Folkestone, Margate, +Gravesend, New Forest, parts of Gloucestershire, Cambridgeshire, and +Devonshire, also in the Isle of Wight and South Wales. + +[Illustration: FIG. 77.--THE MARBLED WHITE--UNDER SIDE.] + +The perfect insect is out in July, during which month the eggs are +deposited on various grasses, or indiscriminately on leaves and stems in +grassy spots. + +The caterpillar feeds on grasses; and, being still small at the end of +the autumn, hybernates during the winter among the stems of grass. It +feeds again in April, and is fully grown by the end of May. Its colour +is a dull green or brownish, with a darker stripe down the back, and +lighter stripes along the sides. Its spiracles are black. + +The chrysalis is pale brown, marked with lines of a slightly darker +shade. It may be found among grass stems, without any attachment, during +the month of June. + + +_The Small Ringlet_ (_Erebia Epiphron_) + +On account of the very limited range of this butterfly, only those who +have the opportunity of visiting its haunts can have any practical +acquaintance with its natural history. It is almost exclusively confined +to the lake district in England, to a few mountainous localities in +Scotland, and to one or two similar localities in Ireland. Its strong +partiality for elevated situations has earned for it the popular name of +Mountain Ringlet. + +The colour of the upper surface (Plate V, fig. 3) is a dark brown, with +a broad band of rusty brown, parallel with the hind margin of each wing, +and broken by the wing rays. Each division of these bands has often a +black central spot, but frequently these are entirely absent. The +colouring of the under side is very similar but less defined, and the +rusty spots of the hind wings are very small. + +The butterfly is out in June and July. The caterpillars, which are +green, with white stripes along the sides, feed on various grasses. They +hybernate during the winter, and change to the chrysalis state in the +following May or June. + + +_The Northern Brown_ (_Erebia Æthiops_) + +The colour of this species (Plate V, fig. 4) is a rich dark brown, with +rust-coloured and black spotted bands arranged something like those of +the last. The markings, however, are very variable. There are usually +four black spots on the band of the fore wings, but the first two of +these are always united, and centred with white. The third is often very +small or entirely wanting. + +The under side of the fore wings is marked something like the upper, but +the hind wings on this side are grey, with two broad bands of a darker +colour. + +As its popular name implies, this butterfly is a northerner. It is +common in Scotland, where it flies in elevated spots. In England it is +confined to the mountainous districts of the north. + +The perfect insect is at large in July and August, during which time the +eggs are deposited on various grasses or on low-growing herbage in +grassy spots. + +The caterpillar is of a brown colour, and has a narrow black stripe down +the middle of the back, and two other stripes, lighter than the ground +colour, one on each side. At about the end of June it turns to a +chrysalis of a brownish colour. + +The food plants of this species include a number of common grasses. + + +_The Speckled Wood or Wood Argus_ (_Pararge Egeria_) + +Most of our butterflies delight in the hot sun, and are to be seen on +the wing only when it is shining brightly. This fact is particularly +noticeable on a bright day with occasional heavy clouds. While the sun's +rays are pouring uninterruptedly on the landscape, numbers of these +light-lovers are to be observed flitting about; but when the dense +shadow of a passing cloud creeps over the ground they rapidly disappear +from view, having settled down to rest on leaves and stems. Then, as +soon as the shadow passes away, the air is again enlivened with their +sports and flittings. + +The Wood Argus is a marked exception to this rule. It delights in the +cool shade of the narrow paths of woods, where it slowly flies up and +down the lonely footpath, taking but little heed of strangers that +intrude on its haunts, and seldom venturing into the full blaze of the +sun unless pursued. Even on dull days it continues its solitary flight, +and may even be seen on the wing while a soft rain is bathing the +dripping foliage. + +The upper surface of this pretty butterfly is shown on Plate V, fig. 5, +and the under side in the accompanying woodcut. Both sides are prettily +marked with various shades of brown and buff, and adorned with +white-centred dark eye-spots which have earned for it the name of Argus. + +[Illustration: FIG. 78.--THE WOOD ARGUS--UNDER SIDE.] + +It first appears on the wing in April, and may be seen from this month +continuously to the end of August. + +The food plants probably consist of many species of grasses, the +cock's-foot (_Dactylis glomerata_) and couch grass (_Agropyron repens_) +being among the number, and the eggs are laid on or in the neighbourhood +of these during the summer months. + +The caterpillar of this species is of a dull greenish or brownish +colour, and it has two whitish stripes (sometimes three) down the middle +of the back, and similar stripes along each side. It hybernates during +the winter, and is full grown in March, when it changes to a dull green +or brownish chrysalis, which is streaked with black, and has a few white +dots on the back. + +It has been stated that the butterfly is on the wing from April to +August, and, according to some authorities, there are no less than three +broods during this time, following each other in rapid succession. It is +common throughout England and Ireland, and is known in parts of +Scotland. + + +_The Wall Butterfly_ (_Pararge Megæra_) + +Belonging to the same genus is another very familiar butterfly--the +Wall--which receives its popular title from its peculiar habit of +frequently resting on walls and stony banks. It is one of the first, if +not _the_ first, to take to the wing in the morning, and is generally +the last to seek its hiding place in the evening. I have seen it +actively flying about during August, as early as 7.30 in the morning, +and found it still flitting from one spot to another along the western +side of a wall as late as 8 in the evening, as if in search of a +convenient shelter for the fast approaching night. + +This pretty 'Brown' must be familiar to the reader, and the coloured +drawing on Plate V (fig. 6) will at once serve for purposes of +identification without the necessity of a wordy description. It may be +mentioned, however, that the male (the sex figured) is smaller than the +female, and is further distinguished by a broad dark oblique band +passing across each fore wing. + +The Wall is a double-brooded butterfly, the first brood appearing in +May, and the second in August. The caterpillars which produce the latter +may be found on the cock's foot (_Dactylis glomerata_) and other grasses +in June, while those of the former are hybernators; and the chrysalides +of the two broods may be found in April and July respectively. + +The colour of the caterpillar is green, with a slightly darker stripe +down the middle of the back, a pale stripe along each side, and another +similar stripe about midway between these two. + +The chrysalis is green with the exception of the more prominent parts of +its surface, which are almost white. + +This species is very common in almost every locality in Britain. + + +_The Grayling_ (_Satyrus Semele_) + +The Grayling is the largest of our 'Browns,' and, although a powerful +flier, it seldom takes long flights. The female, which is shown in fig. +7, Plate V, is really a beautiful creature, the light markings of which +stand out in bold contrast with the deep brown ground colour; but the +male is comparatively dingy, there being much less contrast between the +ground and the markings. He is also smaller than his mate. + +The under side of both sexes is similar (fig. 79), the pattern of the +fore wings being much like that of the other side, but considerably +lighter, and the hind wings are beautifully marbled with various greys +and browns. + +[Illustration: FIG. 79.--THE GRAYLING--UNDER SIDE.] + +This species is not nearly so common as the two preceding, but it is +very widely distributed, and is exceedingly abundant in some parts. On +some of the heathery cliffs and downs of the south and south-west coasts +it is so plentiful that the butterflies are started into the air at +almost every step, for it seldom flies except when disturbed. It is a +common insect in Ireland, and also in parts of Scotland. + +The caterpillar is a hybernator, and may be found feeding on grasses in +the autumn and the spring. It changes to the chrysalis in June, and the +perfect insect is on the wing from June to the beginning of September. + +The colour of the caterpillar is pinkish drab above, and greenish drab +beneath. A dark brown stripe, edged with a lighter colour, passes down +the middle of the back, and a dark line on each side. It changes to a +dark reddish-brown chrysalis on the surface of the ground, or, according +to some observers, a little beneath the surface. + + +_The Meadow Brown_ (_Epinephele Janira_) + +Although this very common butterfly is usually considered to be the +dingiest of its family, yet it must be admitted that the colour of a +freshly emerged specimen is really very rich. + +The male is of a dark brown colour, with an indistinct patch of a +lighter tawny brown near the outer margin of the fore wings, and a +white-centred black eye-spot near the costal angle of the same wings. +The female (Plate V, fig. 8) is of a lighter colour, the eye-spot on her +fore wings is larger and far more conspicuous, and an irregular patch of +light orange brown occupies a large area of each of the same wings. She +is, moreover, larger than her mate, and in every way a more attractive +insect. + +The Meadow Brown abounds everywhere, from June to September, and may be +seen on grass land and waste grounds where other butterflies are seldom +found. + +The caterpillar is green, and is rendered slightly rough by a number of +minute warts. There is also a white stripe on each side. It feeds on +various grasses in the autumn, hybernates during the winter, and is full +grown in May. + +The chrysalis is apple green, spotted with a lighter green, and has +several black markings. + + +_The Large Heath_ (_Epinephele Tithonus_) + +This butterfly is sometimes called the 'Small Meadow Brown,' and is +certainly much like the last species, both in colouring and habits. + +The fore wings of the male (Plate V, fig. 9) are light orange brown, +bordered with dark brown, and having a broad patch of the same across +the middle; and near the costal angle is a round black spot with two +white dots. The hind wings are dark brown with a patch of light orange +brown near the centre, and a small eye-spot near the anal angle. The +female is exactly similar, except that she does not possess the broad +bar on the fore wings. + +[Illustration: FIG. 80.--THE LARGE HEATH--UNDER SIDE.] + +The under side is shown in fig. 80, and is coloured with various shades +of brown. + +This is a very common butterfly, and may be seen during July in most +English counties, also in the south of Scotland, and in a few localities +in the south of Ireland. It frequents meadows, heaths, downs, and lanes, +like _Janira_, but is not nearly so abundant as that species. + +The young caterpillar is hatched in August, and is still very small when +it seeks its winter shelter among the stems of grasses. It resumes +feeding in the following May, and is full grown towards the end of June. +Its colour is very variable--pale green, olive green, or dull brown, +with five longitudinal stripes at about equal distances from each other. +These consist of a dark one down the middle of the back, a pale line +along each side, and another pale line midway between these. + +The chrysalis may be found at the end of June, attached by the tail to +blades of grass. It is of a very light colour, almost white, but adorned +with numerous black lines and patches. + + +_The Ringlet_ (_Epinephele Hyperanthus_) + +This is another rather plainly dressed insect, though somewhat prettily +adorned on the under side. The upper surface is of a very deep sepia +brown, almost black, with a few indistinct black eye-like spots near the +margins. The under side (Plate V, fig. 10) is of a lighter umber brown, +with corresponding eye-spots generally very conspicuous. These spots are +black, with white centres, and generally surrounded by light rings. They +are subject, however, to considerable variation. Those on the upper +surface are sometimes quite absent in the male, but are nearly always +readily perceptible in the female. On the under side, too, they are +occasionally quite absent, while in other varieties they are minute +white-centred dots, without any surrounding light ring. Our coloured +drawing represents the most usual form. + +[Illustration: FIG. 81.--THE RINGLET--UPPER SIDE.] + +The favourite haunts of the Ringlet are the borders of woods, and the +sheltered sides of flowery hedgerows. It is not so widely distributed as +some of the common 'Browns,' but is usually very abundant where it +occurs, sometimes appearing in such numbers that several may be taken +with a single stroke of the net. It does not seem to be a frequenter of +Scotland, and is known in Ireland only in the south. Its head quarters +are the southern and south-midland counties of England. + +The eggs are laid in July on various grasses, on which the young +caterpillars feed from about the middle of August till the cold weather +sets in. They hybernate at the roots of the grasses till the beginning +of the following May, and change to the chrysalis state about the middle +of June, suspending themselves to grass blades by means of their anal +hooks. + +The colour of the caterpillar is dull green or brown, and is marked with +five longitudinal stripes much like those of the Large Heath. + +The chrysalis is pale brown, spotted and striped with a darker shade of +the same colour. + + +_The Marsh Ringlet_ (_Cænonympha Typhon_) + +The upper surface of this butterfly is shown in the first figure of +Plate VI, and the under side in the accompanying woodcut; but it must be +remembered that the species is a very variable one, so much so that it +is almost impossible to give anything like a short and, at the same +time, a satisfactory description. The female may usually be +distinguished by a pale patch across the middle of the fore wings; and +the eye spots of the same wings, always more or less indistinct when +present, are sometimes entirely wanting. The markings of the under side +are even more variable, the transverse bars and the eye spots being +often particularly conspicuous, and at other times hardly discernible. + +[Illustration: FIG. 82.--THE MARSH RINGLET--UNDER SIDE.] + +This is generally spoken of as a northerner, its chief localities being +in the mountainous parts of Scotland and the elevated districts of the +north of England, but in Ireland it extends to the southern ranges. Its +haunts are elevated moors and marshy heaths, where its food plant--the +beak-rush (_Rhyncospora alba_)--abounds, and it is on the wing from the +end of June to August or September. + +The caterpillar is green, with five longitudinal stripes--one dark one, +bordered with yellow, down the middle of the back, and two pale yellow +ones on each side. It is a hybernator, and is full grown about the end +of May, when it suspends itself by the hindmost claspers to a silken +carpet, and changes to a green chrysalis with pale brown wing cases. + + +_The Small Heath_ (_Cænonympha Pamphilus_) + +The last member of the family _Satyridæ_ is the well-known Small Heath, +that may be seen almost all over the British Isles on heaths, meadows +and moors, from May to September. + +The upper surface of this butterfly (Plate VI, fig. 2) is a tawny +yellow, with a dark brown border, and a spot of the same dark tint near +the tip of each fore wing. The under side is much like that of the last +species, but there are no eye spots on the hind wings. + +The eggs of the first brood are laid during May and June on the various +grasses on which the caterpillar feeds. + +The caterpillars that emerge from these are fully grown in July or early +August, and go through their changes during the latter month; but the +later ones hybernate during the winter, and are not full fed till the +following May. + +The colour of the larva is pale apple green, with a wide darker stripe +down the back, two others along the sides, and two more between the +latter and the dorsal stripe. All these five stripes are bordered with a +whitish colour. + +The chrysalis is bright apple green, dotted with white, and the wing +cases are striped with a purple-brown line edged with white. + + + + +CHAPTER XV + +_THE HAIRSTREAKS, COPPERS AND BLUES_ + + +Family--LYCÆNIDÆ + +This is a large family, including as it does no less than nineteen of +the British species. These are all of small size, and are characterised +by their short and jerky flights. They seldom rise much above the +ground, and are consequently very easily caught. + +The caterpillars of this family have all short and rather thick bodies, +shaped very much like that of the wood louse--flattened beneath and very +convex above. + +The chrysalides are generally attached by the 'tail,' and further +secured by a silken cord round the body, as we have already observed in +the case of the _Pieridæ_. + +The perfect insects differ from the preceding species in that all six +legs are perfectly developed and adapted for walking. + +There are only three genera in this large family: + + 1. _Thecla_--The Hairstreaks, with 'tailed' wings. + 2. _Polyommatus_--The 'Coppers.' + 3. _Lycæna_--The 'Blues,' with wings either blue or brown. + + +_The Brown Hairstreak_ (_Thecla Betulæ_) + +The five Hairstreaks which constitute the genus _Thecla_ are all pretty +insects, characterised by hair-like streaks on the under surface. + +_Betulæ_ is the largest of these. Its upper surface is of a deep brown +colour, with orange-brown marks at the anal angles of the hind wings, +and, in the female, a large patch of orange on the fore wings. The under +side (Plate VI, fig. 3) is orange brown, much lighter in the male than +in the female. On the fore wings are two white lines, the inner one of +which is indistinct; and on the hind wings are two others, the outer one +being longer and more distinct than the inner. + +This butterfly is by no means an abundant insect, though it is widely +distributed, and in some places plentiful. Its chief haunts are woods, +and we may mention among its favoured localities Epping Forest, Monk's +Wood in Cambridgeshire, the wooded parts of South Devon and Dorset, New +Forest, Colchester, and Peterborough. + +[Illustration: FIG. 83.--THE BROWN HAIRSTREAK--MALE.] + +The perfect insect is on the wing from July to October, and the eggs are +deposited in the autumn on the twigs of its food plant--the blackthorn +(_Prunus spinosa_). These do not hatch till the following spring. Toward +the end of June the caterpillar is fully fed. + +The colour of the caterpillar is light green, with two white stripes +down the back, and two others along the sides. There are also two small +oblique whitish lines on each side of each segment. + +The chrysalis is smooth, and of a pale brown colour. + + +_The Black Hairstreak, or White-letter Hairstreak_ (_Thecla W-album_) + +The first of the above two popular names has been applied to this +species on account of the very deep brown colour of the upper side, +which colour is often a near approach to black. The second is due to the +W-shaped bend of the white streak of the hind wings. The ground colour +of the under side (Plate VI, fig. 4) is greyish brown, with a bright +orange band, spotted with black near the hind margin of the hind wings. + +[Illustration: FIG. 84.--THE WHITE-LETTER HAIRSTREAK.] + +_W-album_ is a somewhat rare insect, but is occasionally seen in plenty +in a few localities, Cambridgeshire, Berkshire, Epping, Colchester and +Suffolk being among its chief resorts. It is out on the wing in July, +and should be looked for in wooded country where the common elm (_Ulmus +campestris_) and the wych elm (_U. montana_), its food plants, exist. + +The eggs are laid on the twigs of these trees late in the summer, and +the young caterpillars do not appear till the following spring. The +chrysalis may be found attached to an elm twig or leaf about the end of +June. + +The caterpillar is pale green. The ridges along the back are tinged with +yellow, and there are two fine oblique white lines on each side of each +segment. + + +_The Dark Hairstreak_ (_Thecla Pruni_) + +The upper side of this butterfly is very much like that of _W-album_, +but it may be distinguished by the presence of a few orange spots near +the anal angle of the hind wings. The colouring of the under side (Plate +VI, fig. 5) is also very similar, except that the white lines of the +wings are thinner and less distinct than in the last species, and do not +exhibit the W-shaped bend. The orange band of this surface is bordered +on each side with a row of black spots, each of which is touched with a +bluish white or a metallic blue. + +This insect is not by any means common, but has been seen in +considerable numbers in certain localities. It is not found in either +Scotland or Ireland, and its chief haunts in England seem to be in +Huntingdonshire, Cambridgeshire and Northamptonshire. It frequents +wooded country, and flies during June and July. + +The eggs are laid late in the summer on the twigs of the blackthorn +(_Prunus spinosa_), and are not hatched till the following spring. + +The caterpillar, which is pale green, with rows of yellow spots, may be +found in May. + + +_The Purple Hairstreak_ (_Thecla Quercus_) + +This pretty butterfly, by far the commonest of the Hairstreaks, though +comparatively very small, reminds one forcibly of the noble Purple +Emperor. Its haunts are the same oak woods, and its upper surface, +though only a dull dark brown in certain lights, exhibits the same +imperial purple reflections when viewed at certain angles. The purple of +the male extends over the whole of the wings, but that of the female is +confined to a V-shaped patch at the base of the fore wings. In the +latter case, however, the purple is much richer than in the male sex. + +The under side (Plate VI, fig. 6) is coloured with a delicate grey +ground, adorned with a white streak on each wing, and a couple of orange +spots near the anal angle of the hind wings. + +This species is very widely distributed, being common in oak woods in +most parts of England, and also in many parts of Scotland and Ireland. +It flies around the branches of the trees, and often disappoints the +collector by keeping far beyond the reach of his net. + +[Illustration: FIG. 85.--THE PURPLE HAIRSTREAK--MALE.] + +Those in search of this pretty insect should ramble in oak woods, +preferably in the south of England, during July and August. The eggs may +be found glued to the twigs throughout the winter, and the larvæ may be +beaten from the branches of the oak in June. + +The colour of the caterpillar is brownish or pinkish green, with a row +of V-shaped marks down the back. + +The chrysalis is of a brown colour, short and thick, and may be found +either attached to oak leaves, or under the surface of the earth at the +foot of the tree on which the caterpillar fed. + + +_The Green Hairstreak_ (_Thecla Rubi_) + +Next to _Quercus_, this is the most plentiful of the genus. It frequents +woods and heaths in nearly every county in England, and is also found in +parts of Scotland and Ireland. It is peculiar among British butterflies +as being the only one that exhibits a bright green colour. It also +differs from the other Hairstreaks in two important particulars, for the +hind wings, though angled at the hind margin, are not 'tailed,' and the +characteristic hairstreak which gives the popular name to the genus is +here represented only by a series of white dots across the wings, or, in +some cases, by one or two dots on the hind wings only. + +[Illustration: FIG. 86.--THE GREEN HAIRSTREAK.] + +The upper side is dark brown, displaying metallic reflections when +viewed in a strong light. The under side is represented in fig. 7 of +Plate VI. + +The chief food plants of this species are the bramble (_Rubus +fruticosus_), the birch (_Betula alba_), and the broom (_Cytisus +scoparius_). + +The perfect insect flies in May and June, and the eggs are deposited +during the latter month on the above plants. The caterpillars are full +fed in July, and change to the chrysalis state towards the end of the +summer. + +The colour of the caterpillar is pale green, with a yellow stripe and +several white oblique lines along the sides, also a yellowish stripe +down the back. + +The chrysalis is short and thick, and of a dark brown colour. + + +_The Large Copper_ (_Polyommatus Dispar_) + +Our next genus contains only two British species. The first of +these--the Large Copper--was once a common insect at Whittlesea in +Cambridgeshire, and in some of the fens of Huntingdonshire, but is now +feared to be quite extinct, as none have been seen for many years. The +last capture was made in 1847 in Huntingdonshire. However, it _may_ turn +up again; and even if it does not, it would be a pity to allow the +memory of so fine an insect to die out; so we find room to figure it +(Plate VI, fig. 8), and append a few remarks. + +There is a very great difference between the male and the female. The +former is of a brilliant copper hue, and all the wings have a black +margin and a black streak near the middle. The female is larger; and the +coppery colour is much redder. The black border of the fore wings is +wider, and there are also several large black spots on these wings. The +hind wings are almost entirely covered with black, with the exception of +a broad coppery band near the hind margin. + +The food plant of the caterpillar appears to have been the water dock +(_Rumex Hydrolapathum_), on which the eggs were laid late in the summer. +It is probable that the caterpillar was a hybernator, seeking its winter +shelter while still very young; and it was full fed in June. + +Its colour was green, with a darker stripe of the same colour on the +back; and the chrysalis was attached by anal hooks and a cord round the +body. + + +_The Small Copper_ (_Polyommatus Phlæas_) + +The only other British member of the genus _Polyommatus_--the Small +Copper--is one of the commonest of our butterflies. It may be found in +nearly all parts of the British Isles from April to September, more +particularly in April, June, _and_ August, for it is apparently triple +brooded. + +This brilliant and lively little insect is shown on Plate VI (fig. 9), +and, being so very familiar, needs no description. + +The caterpillar feeds on different species of dock--the broad-leaved +dock (_Rumex obtusifolius_), the fiddle dock (_R. pulcher_), the sorrel +(_R. acetosa_), and the sheep sorrel (_R. acetosella_); also on the +ragwort (_Senecio Jacobæa_). It is full fed about three weeks after +hatching, and then changes to a small and stout chrysalis, of a pale +brown colour, on the leaf of its food plant. + +The caterpillar itself is green, with a reddish line on the back and on +each side; and it glides over the surface of the leaves something after +the manner of a slug, without exhibiting any very apparent motion of its +short legs and claspers. + + +_The Tailed Blue_ (_Lycæna Bætica_) + +We now come to a genus containing no less than ten species of beautiful +little butterflies, known commonly as the 'Blues;' but one of them +exhibits no trace of the colour so characteristic of the group, although +it resembles the others in structure and habits. + +Our first example is the Tailed Blue, known also as the Pea-pod Argus. +The upper side of this insect (Plate VI, fig. 10) is of a dull smoke +colour, exhibiting purple-blue reflections, which are, in the female, +confined to distinct blotches on the bases of the wings, but in the male +are less noticeable, and extend over the whole surface. The hind margin +of the hind wings has a row of spots, more or less distinct, and much +more prominent in the female than in the male. The under side is +beautifully marked with bands of fawn and grey, and with two spots of +brilliant metallic green in the anal angle of the hind wings. + +[Illustration: FIG. 87.--THE TAILED BLUE--UNDER SIDE.] + +This butterfly abounds in the countries of South Europe, where the +caterpillar feeds on the pods of certain leguminous plants; but only a +few stragglers have been taken in England, so that its reputation as a +true Britisher is very uncertain. It is highly probable that the two or +three specimens caught on our south coast were blown over from the +Continent, and that the insect has never bred on this side of the +Channel. + + +_The Silver-studded Blue_ (_Lycæna Ægon_) + +The upper surface of the male (Plate VI, fig. 11) of this species is +purple blue, with a black border on the hind margins of all wings. The +female (fig. 12 of the same plate) is of a very dark smoky-brown colour, +often with a bluish tinge, and has generally a row of orange spots near +the hind margin of the hind wings. + +The under side of both sexes is similar, and is illustrated in the +accompanying woodcut. The ground colour is bluish grey, and is marked +with a number of black spots surrounded by light rings. Along the hind +margin of the hind wings is a row of orange spots, each bordered with +black on the inner side, and with a silvery blue on the outer. + +[Illustration: FIG. 88. THE SILVER-STUDDED BLUE--UNDER SIDE.] + +This insect appears in July, and is common in many dry, sandy, or chalky +spots in various parts of England, and also in a few localities in +Scotland and Ireland. It has been reported as abundant at Darlington and +in certain localities in Lancashire, but its head quarters are +undoubtedly the chalk downs and dry gravelly banks of the southern +counties. + +The caterpillar feeds on the bird's-foot (_Ornithopus perpusillus_), and +is full grown towards the end of June. Its colour is yellow or grey, +with a brown dorsal stripe, a white line on each side, and pale oblique +lines near the former. About the end of June it changes to a dull green +chrysalis, with projecting wing cases. + + +_The Brown Argus_ (_Lycæna Astrarche_) + +Neither male nor female of this species exhibits any trace of blue. The +upper surface, shown in fig. 13 of Plate VI, is coloured with a warm +brown, and all four wings have a row of orange spots near the hind +margin. The fore wings have also a central black spot. The under +surface, drawn on the same plate (fig. 14), is bluish grey, with a +border of orange spots on each hind margin as on the other side. There +are also numerous black spots in light rings, the arrangement of which +will be seen in the figure. + +Some species of butterflies and moths are so variable in their colouring +and markings that varieties have often been mistaken for distinct +species; and, in other cases, distinct species are sometimes so similar +in character that they are looked upon as identical. + +A butterfly that closely resembles the normal Brown Argus in many +points, and named _Artaxerxes_, has often been described as a distinct +species, but is now, I believe, recognised by most entomologists as a +constant variety of the present species. + +It differs from the normal type in having a _white_ instead of a _black_ +spot in the centre of the fore wings, and the border of orange spots is +often very indistinct. On the under side, too, instead of black spots in +white rings, it has white spots, with little or no trace of a black +centre. + +The ordinary Brown Argus is a southerner, and is particularly abundant +on the chalk downs of the south coast and the Isle of Wight, but +_Artaxerxes_ is to be found only in Scotland and the north of England; +and it is interesting to note that, between these northern and southern +districts, intermediate varieties are to be met with. + +Again, _Astrarche_ is a double-brooded butterfly, appearing on the wing +in May and August; while _Artaxerxes_ is single brooded, flying at +midsummer. This fact has lent support to the opinion that the two are +distinct species; but it must be remembered that several insects that +are single brooded in one country are double brooded in a warmer +climate. + +The caterpillar of _Astrarche_ feeds on the hemlock stork's-bill +(_Erodium cicutarium_). It is of a pale yellow colour, with a brownish +line on the back; and is full fed in April and July. + + +_The Common Blue_ (_Lycæna Icarus_) + +Although this pretty little butterfly is so common that it is almost +sure to be known to all who take any interest in insect life, yet it is +important to observe it carefully, since it is an easy matter to +confound it with other species of the same genus. + +The upper surfaces of the two sexes are very different, that of the male +(Plate VI, fig. 15) being a beautiful lilac blue; and that of the +female (Plate VI, fig. 16) a dark brown, powdered with blue at the bases +of the wings, and having _generally_ a border of orange spots, more or +less defined, on the hind margins of all wings. + +[Illustration: FIG. 89.--THE COMMON BLUE--UNDER SIDE.] + +The under side, shown in the accompanying woodcut, is ashy brown; warm +in the female, but paler in the male. The hind wings, and sometimes all +four, are bordered with orange spots; and this species may be +distinguished from _Astrarche_ by the presence of two black spots, in +white rings, near the base of the fore wings. + +There will be no need to name localities for this insect, as it is +abundant everywhere, frequenting meadows, heaths, and all waste places. +It is double brooded, and is on the wing continuously from May to +September, the first brood enduring from May to July, and the second +from July to the end of the warm weather. + +The caterpillar is green, with a dorsal line of a darker tint, and a row +of white spots on each side. It feeds on clover (_Trifolium pratense_ +and _T. repens_), bird's-foot (_Ornithopus perpusillus_), bird's-foot +trefoil (_Lotus corniculatus_), and the rest-harrow (_Ononis spinosa_). + +The chrysalis is short and rounded, of a dull green colour, tinged with +brown on the under surface. + + +_The Clifden Blue_ (_Lycæna Bellargus_) + +Our coloured representations of this beautiful blue (Plate VI, figs. 17 +and 18) show that here also there is a great difference between the male +and female. The former is a most lovely and brilliant sky blue, bordered +by a fine black line; and the latter is a dull dark brown, with a more +or less distinct border of orange spots, and the bases of the wings are +powdered with scales of a tint corresponding with those of the male. In +both sexes the fringe is very distinctly barred with dark brown. + +[Illustration: FIG. 90.--THE CLIFDEN BLUE--UNDER SIDE.] + +The under side (fig. 90) is similar in both sexes--greyish brown, with +a border of reddish spots, and a number of black spots in white rings, +the arrangement of which is here represented. + +The butterfly frequents chalky downs, chiefly in the south of England, +and seems to be unknown in Scotland and Ireland. The Isle of Wight, and +the chalky downs and banks of Sussex, Surrey, and Kent, are its +favourite localities; and even in these it is generally very local, +sometimes swarming on a grassy bank of no great extent, when the +surrounding neighbourhood, though apparently equally suitable to its +requirements, does not harbour a single specimen. It is on the wing in +May and June, and again in August. + +The caterpillar is green, with two rows of yellow streaks on the back, +and a yellow stripe on each side. It feeds on the Dutch clover +(_Trifolium repens_), horse-shoe vetch (_Hippocrepis comosa_), and +various other leguminous plants. + + +_The Chalk-Hill Blue_ (_Lycæna Corydon_) + +The male of this species (Plate VII, fig. 1) is readily to be +distinguished from all other members of the genus by its pale glossy +blue, but the female (fig. 2 of Plate VII) so closely resembles that of +_Bellargus_ that it is often a somewhat difficult matter to discriminate +between them. The following, however, are a few points worthy of +observation: The upper side of the female _Corydon_ has the bases of the +wings more or less sprinkled with the pale silky blue that characterises +the male; and the black bars of the fringe are _usually_ broader in +_Corydon_ than in _Bellargus_. The black-centred spots of the under side +are also usually more conspicuous in the former species than in the +latter. + +[Illustration: FIG. 91.--THE CHALK HILL BLUE--UNDER SIDE.] + +The difficulty of identification is increased by the fact that both +these butterflies frequent similar localities, and are often on the wing +at the same time; but although _Corydon_ is certainly a frequenter of +chalky districts, yet it is often found plentifully in districts far +removed from the chalk, notably at Arnside in Lancashire, and in Epping +Forest. + +The butterfly is out in June and July. The caterpillar is green, with +two rows of short yellow streaks on the back, and a yellow stripe on +each side. It feeds on the purple and Dutch clovers (_Trifolium +pratense_ and _T. repens_), bird's-foot trefoil (_Lotus corniculatus_), +horse-shoe vetch (_Hippocrepis comosa_), and lady's fingers (_Anthyllis +vulneraria_). + + +_The Holly Blue_ (_Lycæna Argiolus_) + +While all the other Blues delight to sport on low flowery banks in the +full blaze of the summer's sun, the Holly Blue prefers to flit among the +branches of trees, often many feet from the ground. The larva feeds on +the flowers of the holly (_Ilex Aquifolium_) in the spring, and on those +of the ivy (_Hedera Helix_) late in the summer; also on the alder +buckthorn (_Rhamnus Frangula_); and it is in localities where these grow +that we may find this lovely Blue sporting among the branches, or +resting on a leaf with its wings folded together, thus making itself +conspicuous among the dark foliage by exposing the pale silvery blue of +its under surface. + +The upper sides of both the male and female are shown on Plate VII +(figs. 3 and 4 respectively), where the beautiful lilac blue will be +seen to have a border of black, wider in the latter than in the former. + +[Illustration: FIG. 92.--THE HOLLY BLUE--UNDER SIDE.] + +The under surface is spotted with black, as shown in fig. 92, and has no +border of orange spots. + +This is a double-brooded butterfly, appearing first in April and May, +and then again in August. It is not at all uncommon in the south of +England, and extends northward as far as the Lake District, but is not +found in Scotland. It is generally distributed throughout Ireland. + +The caterpillar may be looked for in June and October. It is light +green, with a line of dark green down the back. + + +_The Mazarine Blue_ (_Lycæna Semiargus_) + +The male (Plate VII, fig. 5) is deep purple blue, with a narrow +dark-brown border, and the female (fig. 6 of the same plate) dark brown. +The under side of both sexes is light greyish-brown or drab, with a row +of black spots in white rings parallel with the hind margin of each +wing, and no reddish or orange spots. + +This pretty butterfly seems to have been plentiful in several localities +some years since, but has not been seen for a long time; and it is +probable that its reckless slaughter by those who catch all the pretty +butterflies they can secure either for ornament or for gain has caused +its name to be permanently removed from our list of natives. + +[Illustration: FIG. 93.--THE MAZARINE BLUE--UNDER SIDE.] + +It was formerly abundant in Dorset, Hereford, Glamorganshire, and near +Shirley, and was on the wing in June and July, but it disappeared from +our view before a full account of its life history had been prepared. + + +_The Small Blue_ (_Lycæna Minima_) + +We now come to the smallest of all British butterflies--a little insect +that measures less than one inch from tip to tip when its wings are +expanded. Its upper surface is of a dull and dark-brown colour, the +bases of the wings being dusted with blue in the case of the male. The +under side is pale drab, tinged with greenish blue at the bases of the +wings, and marked with black spots in light rings as shown in the +accompanying figure. The upper side is represented in fig. 7 of Plate +VII. + +[Illustration: FIG. 94.--THE SMALL BLUE--UNDER SIDE.] + +This butterfly is on the wing in May and June, and during the latter +month the eggs are deposited on the flowers of the lady's fingers +(_Anthyllis vulneraria_). + +The caterpillars are hatched in about a week, and commence feeding on +the calyx of the buds, and soon burrow into them till they are quite +concealed. + +The colour of the caterpillar is brownish, with a darker stripe on the +back, and a row of oblique brown streaks on each side. + +This species is widely distributed in England, and is plentiful in most +chalky and limestone districts. It is also found in parts of Scotland +and Ireland. + + +_The Large Blue_ (_Lycæna Arion_) + +The last of our Blues is the largest of the genus, and is, with the +exception of _Semiargus_, the rarest. It is a very local insect, +appearing in small numbers, during June and July, in parts of South +Devon, Gloucestershire, Northamptonshire, and a few other counties. + +[Illustration: FIG. 95.--THE LARGE BLUE--UNDER SIDE.] + +The colour of the upper side is a dark and rich blue, with a broad dark +border on the hind margins, and a group of black spots near the centre +of the fore wings. The under side (fig. 95) is of a pearly grey, without +any red spots, but having a double border of black spots, and also an +irregular row of black spots in white rings across the middle of each +wing. + +The caterpillar feeds on thyme (_Thymus Serpyllum_), on which plant the +eggs are laid singly, generally on the flower heads. + + + + +CHAPTER XVI + +_THE DUKE OF BURGUNDY AND THE SKIPPERS_ + + +Family--ERYCINIDÆ + +_The Duke of Burgundy_ (_Nemeobius Lucina_) + +The family _Erycinidæ_ has only one British representative, commonly +known as the Duke of Burgundy Fritillary, but although this butterfly +certainly resembles the Fritillaries in general appearance (see figs. 9 +and 10 of Plate VII), its habits and life history present many points of +difference from these. + +The upper side is chequered with black and tawny brown, the fringe is +white and barred with dark brown, and a row of tawny spots with black +centres border the hind margins. The under side has two rows of white +spots, one near the base, and the other across the centre of each wing. + +The male has only four legs adapted for walking, but the female has six. + +The butterfly is out in May and June, and frequents the paths and open +spaces of woods, chiefly in the south of England, but it has been taken +in some of the northern counties. + +The caterpillar (Plate VIII, fig. 6) is not spiny like those of the true +Fritillaries, but more closely resembles those of the Blues, being +somewhat of the form of a woodlouse. It is reddish brown, with tufts of +hair, black spiracles, and a dark line down the back. It feeds on the +primrose (_Primula acaulis_) and the cowslip (_P. veris_), and may be +found during June, July and August. + +When fully grown, the caterpillar secures itself to a leaf or stem by +means of its anal claspers and a silken cord round its body, and changes +to a short, thick, hairy and light-coloured chrysalis (Plate VIII, fig. +11), which is marked with several black spots. In this state it spends +the winter, and emerges early in the following summer. + + +Family--HESPERIIDÆ--THE SKIPPERS + +This family contains eight small species, none of which are remarkable +for brilliancy of color. They are, nevertheless, very interesting +creatures, for they exhibit peculiarities of structure and habit that +render them singular among the butterflies, and seem to show a sort of +cousin relationship with the moths. They have thick bodies that remind +us somewhat of the _Noctuæ_. Their heads are broad, so that the antennæ, +which are slightly hooked at the tips, are rather wide apart at the +bases. When at rest, they neither press their wings together over their +back like the other butterflies, nor do they set them horizontally after +the manner of the moths, but seem to lay claim to an intermediate +position in the scale of Lepidopterous insects by holding them in a half +elevated position. Their flight, too, is not graceful like that of most +other butterflies, nor even so steady as that of the little flitting +blues, but brisk and erratic, and resembling the fitful motions of moths +disturbed from their slumberings at unwonted hours. Thus they have +earned their popular title of skippers from their habit of skipping +rather than flying from flower to flower. All the three pairs of legs of +these butterflies are fully developed for walking. + +The caterpillars have rather large heads, and their bodies taper from +the middle toward both extremities. Like the larvæ of many moths, they +hide themselves in leaves which they have rolled and secured with silken +threads; and when about to change to the chrysalis state, they also spin +silken cocoons for their further protection. + + +_The Grizzled Skipper_ (_Syrichthus Malvæ_) + +The ground color of this species is a very dark brown, relieved by a +number of square white spots arranged as shown in fig. 11 of Plate VII. +The fringe is wide, and barred with the same two colours, arranged +alternately. The pattern of the under side is similar, but the dark +brown of the upper surface is replaced by a lighter olive tint. + +The butterfly may be looked for in May in the open spaces of woods, +particularly in damp places. It is common all over England, and is found +also in the south of Scotland. + +The caterpillar is either green or brownish, with a darker dorsal stripe +of the same color, and two white lines on each side. It feeds on the +raspberry (_Rubus idæus_), the bramble (_R. fruticosus_), and the +strawberry-leaved cinquefoil (_Potentilla Fragariastrum_), and is full +fed about the end of June. + +The chrysalis is greyish, spotted with black. It is rather elongated, +and without angles, but has a short and sharp projection extending +backwards from the 'tail.' + + +_The Dingy Skipper_ (_Nisoniades Tages_) + +Colour--a dingy brown, indistinctly barred and spotted with a darker +tint, and having a row of small white spots just inside the fringe of +the hind margins. Under side--a paler brown, with rows of small white +spots. + +This butterfly is common in all parts of England, and is found in a few +localities in Scotland and Ireland. It frequents dry banks, and is +particularly partial to the chalky districts of the south-eastern +counties. It is on the wing in May, and a second brood appears in lesser +numbers in August. + +The caterpillar is pale green, with two yellow stripes on each side, and +a row of black spots above each stripe. It feeds on the bird's-foot +trefoil (_Lotus corniculatus_), and may be found in June, and again in +September. + +The chrysalis (Plate VIII, fig. 12) is shaped something like that of the +last species, and is coloured green on the front segments, and a rose +red on the abdomen. + +The perfect insect is represented in fig. 12 of Plate VII. + + +_The Small Skipper_ (_Hesperia Thaumas_) + +In briefly describing the various British butterflies no mention has +been made, except in a few cases, of the shape of the wings, this matter +having been left to the reader's own observations of our illustrations. +We will, however, call attention to the somewhat square-cut form of the +wings of _Thaumas_ and the following species. + +The above-named butterfly (Plate VII, fig. 13) is a lively-looking +little insect, its wings being of a bright tawny orange colour, bordered +with black, beyond which is a light fringe. The male, which is the sex +figured, is distinguished from the female by an oblique black streak +across the middle of the front wings. The under side is orange, with a +decidedly greenish tinge. + +The butterfly is out in July, and is very abundant and widely +distributed. It lays its eggs on various grasses, particularly the +meadow soft-grass (_Holcus lanatus_). + +The caterpillar hybernates through the winter, and is full fed in the +following June, when it changes to a green chrysalis after spinning a +light silken cocoon among the blades of grass. The colour of the +caterpillar is green, with six longitudinal white stripes--two on the +back, and two on each side. + + +_The New Small Skipper_ (_Hesperia Lineola_) + +A few years since (1888) a butterfly was taken in one of our +south-eastern counties that closely resembled the well-known _Thaumas_ +(or _Linea_), but which turned out to be a species not previously known +in Britain. When, however, the distinguishing features of the new +butterfly were made known, several entomologists discovered that they +had already secured the new prize, but that, being ignorant of its +characteristics, they had placed it in their series over the label +_Thaumas_. + +Since the above date, this new insect (Plate VII, fig. 18), which is +named _Lineola_, has been taken in considerable numbers at Leigh, +Harwich, Southend, and near Shoeburyness in Suffolk, as well as in the +Fens of Huntingdonshire; and it is highly probable that it may turn up +in various other localities where it has not yet been observed. + +It appears on the wing about the first week of July, a little later than +_Thaumas_, but the two kindred species are often found flying together. + +The chief points by which we distinguish _Lineola_ from the last species +are these: The general appearance of the wings is a bit dingier than in +_Thaumas_; the inner portion of the hind wings is of a bright tawny +colour in _Thaumas_ but not in _Lineola_; the tips of the antennæ are +yellow beneath in _Thaumas_, but black in _Lineola_; and the black +streak across the fore wings of the latter species is short and +generally broken. + +The eggs of _Lineola_ are laid at the end of July or beginning of August +on various grasses, chiefly the various species of _Triticum_, but do +not hatch till the following April. + +The larva is full fed about the end of June or beginning of July, and +then changes to a long yellowish-green chrysalis, from which the perfect +insect emerges in two or three weeks. + + +_The Lulworth Skipper_ (_Hesperia Actæon_) + +Although this species is somewhat similar to the two preceding, it may +be readily distinguished by the heavy clouding of dull greenish brown +that almost covers the wings. The male, which is shown in fig. 14 of +Plate VII, has a black streak across the fore wings, and the female +possesses a semicircular row of tawny spots near the tip of the same +wings, and also a tawny streak near the centre. + +This is a very local species, having been found only in a few +localities. At Lulworth Cove and 'Burning Cliff' in Dorset it has been +met with in profusion. In Devon it frequents the rough ground near the +cliffs at Sidmouth and Torquay; and it has also been reported as +appearing at Stratford-on-Avon, Shenstone near Lichfield, and the +neighbourhoods of Swanage and Tyneham. + +One can scarcely hope to see this insect at large without making a +special trip to one of its favourite haunts, in which case a day should +be chosen toward the end of July or early in August. + + +_The Large Skipper_ (_Hesperia Sylvanus_) + +During May, June, and August this butterfly may be seen on grassy banks +in nearly every part of England, as well as in certain localities of +Scotland and Ireland. + +The wings are all of a bright orange-brown colour, with a narrow black +border, inside which is a broad shading of brown. The latter colour +usually completely covers the hind wings with the exception of about +half a dozen squarish spots; and the same colour, together with the dark +brown wing rays, breaks up the light ground of the fore wings, often +forming several squarish and triangular patches, most distinct near the +tips. The male (Plate VII, fig. 15) may be readily distinguished from +the female by the presence of a thick dark brown streak across the fore +wings. + +The under side of both sexes is pale tawny brown, with a greenish tinge; +and has several rather indistinct yellowish spots. + +The larva is of a dull green colour, with a dark line on the back. Its +upper surface is dotted with black, and there are white spots on the +under side of the tenth and eleventh segments. It feeds on several kinds +of grasses, some of its favourites being the meadow soft grass (_Holcus +lanatus_), the cock's-foot (_Dactylis glomerata_), and couch grass +(_Agropyron repens_). + + +_The Silver-spotted Skipper_ (_Hesperia Comma_) + +This species is very similar on the upper side to the last, except that +the squarish spots of both fore and hind wings are much paler and much +more distinct; and here, too, the male (Plate VII, fig. 16) is to be +distinguished from the female by a black streak crossing the front wings +obliquely. The under surface has a greenish tinge, more particularly on +the hind wings; and this side is conspicuously marked with a number of +_white_ square spots with sharp outlines, arranged as shown in fig. 96. + +[Illustration: FIG. 96.--THE SILVER-SPOTTED SKIPPER--UNDER SIDE.] + +Although common in some localities, this butterfly is not widely +distributed. It is confined to some of the southern and midland counties +of England, and is particularly partial to the chalk districts of the +south-east. On the chalk downs of Kent, Surrey, and Sussex it is +moderately common. It is on the wing during July and August. + +The caterpillar feeds on certain leguminous plants, among which are the +bird's-foot (_Ornithopus perpusillus_) and the bird's-foot trefoil +(_Lotus corniculatus_). + + +_The Chequered Skipper_ (_Carterocephalus Palæmon_) + +This is another local insect, more so even than the last, but it +sometimes appears in profusion in certain limited districts. Kettering, +Oundle in Northamptonshire, and Monk's Wood in Huntingdonshire are +places where it has been taken freely. It appears in June. + +The wings are chequered with very dark brown and orange. The fore wings +are bordered with small rounded yellow spots, and beside these there are +about nine very conspicuous yellow spots on the fore wing and three on +the hind wing. The arrangement of these markings may be seen in fig. 17 +of Plate VII. + +The caterpillar feeds on the greater plantain (_Plantago major_). + + + + +PART IV + +COMMON BRITISH MOTHS + +CHAPTER XVII + +_SPHINGES_ + + +We have already observed the chief features by which we are able to +distinguish between butterflies and moths (page 56), so we shall devote +the present division to a description of the characteristics and life +histories of some of the latter insects. + +The number of British butterflies is so limited that space could be +found for a brief description of every species, but with moths the case +is very different. There are about two thousand known British species of +this division of the Lepidoptera, and every year adds some newly +discovered insects to this long list; we shall therefore have to content +ourselves with making a selection of these for individual mention. + +In doing this I shall endeavour to provide the young entomologist with a +fairly representative list--one that will enable him to become more or +less intimately acquainted with all the principal divisions of the +_Heterocera_; and his attention will be drawn especially to many which +may be described as 'common' or 'generally distributed,' so that during +his first few seasons at collecting he may be enabled to identify and +study a fair proportion of his captures. Occasionally, however, one of +the rarer species will be described in order to illustrate some striking +characteristic. + +We shall commence with the tribe of _Sphinges_ or _Hawk Moths_. + +This group consists of three families--the _Sphingidæ_, including the +largest of the 'Hawks,' and the 'Bee Hawks,' the _Sesiidæ_ or +'Clearwings,' and the _Zygænidæ_, including the 'Foresters' and the +'Burnets'--numbering in all about forty species. + + +Family--SPHINGIDÆ + +This family is named from a fancied resemblance of the larvæ to the +celebrated Egyptian sphinx. The perfect insects have very thick bodies, +generally tapering toward the tail, and their wings are rather narrow in +proportion to the length, but are exceedingly powerful, and the flight +is, with one or two exceptions, very rapid. The antennæ terminate in a +small and thin hook. + +Most of these insects fly at dusk, but a few delight in the brightness +and heat of the midday sun. In either case the velocity of their flight +is generally so great that it is a difficult matter to follow them with +the eye, and a still more difficult matter to secure the insects in the +net; consequently, the best way to study them is to search out the larvæ +on their food plants, and rear them till they attain their perfect form. + +The larvæ of the _Sphingidæ_ are large and smooth, and most of them have +a horn projecting from the top of the last segment but one. They all +undergo their metamorphoses under the surface of the ground. + + +_The Death's-Head Hawk_ (_Acherontia Atropos_) + +Our first example of the Sphinges is the beautiful Death's-Head Hawk +Moth--an insect that often attains a breadth of five inches from tip to +tip when the wings are fully expanded. Its popular title has been +applied on account of the peculiar markings of the thorax, which are +said to resemble a human skull; and this feature has certainly some +connection with the superstitious beliefs of ignorant country folk +concerning this moth. But this characteristic is probably not the only +one that has caused the creature to be regarded with superstitious +alarm. Both its superior dimensions and nocturnal habits serve to +intensify the unfounded fear; but, what is particularly striking and +unique about it is its power of uttering a squeaking sound, which it +does when disturbed. Even the earlier stages of the insect possess this +strange power. The caterpillar makes a peculiar snapping noise when +irritated, and the chrysalis has been observed to squeak shortly before +the emergence of the perfect form. + +The fore wings of this moth are of a very rich dark brown, beautifully +mottled with lighter tawny shades, and with a small but conspicuous +yellow dot near the centre. The hind wings are yellow, with a black band +and margin; and the body is yellow, with six broad black bands, and six +large blue spots down the middle. + +[Illustration: FIG. 97.--THE DEATH'S-HEAD HAWK MOTH.] + +The moth is rather widely distributed, and even common in some parts, +but is not nearly so often met with as the larva. It is on the wing +during August and September. + +It is probable that the reader will never have an opportunity of +capturing the perfect form of this remarkable species, but he may with a +little perseverance obtain some caterpillars and rear them. These larvæ +feed on the potato, the deadly nightshade (_Atropa Belladonna_), and the +woody nightshade (_Solanum Dulcamara_); and they are well known to +potato growers in some parts of the country. + +The colour of the caterpillar is generally pale yellow, with numerous +small black dots, and seven oblique violet stripes on each side. The +horn is yellowish and rough, and is bent downward, but recurved again at +the tip. + +It feeds during the night, and remains hidden throughout the daytime. In +August it is fully grown, and then retires into the ground to undergo +its transformations. + +[Illustration: FIG. 98.--THE LARVA OF ATROPOS.] + + +_The Privet Hawk_ (_Sphinx Ligustri_) + +This is another fine moth, measuring nearly four and a half inches from +tip to tip. It is represented in the centre of Plate IX in its natural +colours, so that it need not be described. + +The perfect insect flies in June and July, and, although common, is not +frequently seen at large. The larvæ, however, are to be met with in +abundance in privet hedges. Even in the centres of large towns we may +see them resting on the topmost twigs of a privet hedge, their beautiful +green tint closely resembling that of the surrounding leaves. After a +little experience they may be readily discerned by a careful observer, +but there are certain signs by which their presence may be proved before +they have been actually seen. Sometimes a number of the twigs are +completely stripped of their leaves, even the midribs and the leaf +stalks being almost or entirely devoured; and beneath the bushes are +the large black masses of excrement that tell of the marauders above. +When found, these larvæ should always be removed on a piece of the twig +to which they are attached, for they hold on so firmly by their claspers +that it is sometimes almost impossible to remove them from their hold +without injury. + +These caterpillars may easily be distinguished from those of the other +'hawks' by the seven oblique stripes which adorn the sides. These are +each composed of two colours, white and lilac, and form a pretty +contrast with the bright green of the rest of the body. The horn is +smooth and curved, and is black with the exception of part of the under +side, which is yellow. + +They are fully grown in August, and from the end of this month till the +following June the chrysalides may be dug out from under privet and +lilac bushes, both of which are attacked by the larva. + + +_The Spurge Hawk_ (_Deilephila Euphorbiæ_) + +This is a very rare British species; in fact, it has never been seen in +this country in its perfect state, but the larva has been found +plentifully at Appledore and Braunton Burrows, in North Devon, feeding +on the sea spurge (_Euphorbia Paralias_). + +The perfect insect is shown on Plate IX (fig. 2). + +[Illustration: FIG. 99.--THE CATERPILLAR OF EUPHORBIÆ.] + +The caterpillar is black, with a large number of small yellowish white +dots, and two rows of spots of the same colour on each side. There is +also a red line on each side, and another down the middle of the back. +The horn is rough and red with a black tip. It feeds during August and +September. + + +_The Small Elephant Hawk_ (_Chærocampa Porcellus_) + +This pretty insect is one of the smallest of our hawk moths. It is +widely distributed, being met with in many parts of England and in the +south of Scotland. It flies in June. + +The fore wings are of a dull yellow colour, with rosy-red hind margins, +and a broad border of the same tint on the costal margin. The hind wings +have also a rosy-red hind margin, and are smoky black along the costæ, +and yellow in the anal angle. The body is coloured with bright rose-red, +tinged with olive on the foremost and hindmost segments. + +The popular name of this and the following species has been applied +because of the power which the caterpillar has of extending and +retracting its front segments, a peculiarity which has given the idea of +a semblance to the elephant's proboscis. The colour of the caterpillar +is light-brown or green, mottled with dark-brown, dark-green, or black. +It has a conspicuous eye-like spot on each side of the fifth and sixth +segments, and has no horn. + +[Illustration: FIG. 100.--THE SMALL ELEPHANT HAWK MOTH.] + +This larva may be found in July and August, feeding on species of +bedstraw (_Galium verum_, _G. Mollugo_, and _G. palustre_), willow herb +(_Epilobium hirsutum_), or the purple loosestrife (_Lythrum Salicaria_). + + +_The Large Elephant_ (_Chærocampa Elpenor_) + +This species (Plate IX, fig. 3) is very similar to the last in form and +markings; but is, as its name implies, larger. + +The caterpillar, too, is very like that of the last species, but may be +distinguished from it by the possession of a short black horn, tipped +with white, on the 'tail.' Its colour is green or brown, mottled and +spotted with black. The eye-like spots on its fifth and sixth segments +are black, and each contains a brown spot surrounded by a white line. + +Its chief food plants are the hairy willow herb (_Epilobium hirsutum_), +three species of bedstraw (_Galium verum_, _G. Mollugo_ and _G. +palustre_), the purple loosestrife (_Lythrum Salicaria_), and the +enchanter's nightshade (_Circæa lutetiana_). It will also feed on the +vine and the apple in confinement. + + +_The Eyed Hawk_ (_Smerinthus Ocellatus_) + +Our next genus (_Smerinthus_) contains three well-known moths, all of +which have the hind margin of the fore wings angulated or indented. + +The first is the Eyed Hawk, represented in fig. 4 of Plate IX and named +after the beautiful and conspicuous eye-like spot near the anal angle of +each hind wing. + +The caterpillar has a rough green skin, sprinkled with white dots, and +marked with seven oblique white lines on each side, each of which is +bordered with dark green above. The spiracles are pinkish, surrounded by +violet rings; and the horn is blue. + +The moth flies during May, June, and July; and the caterpillar may be +found in plenty during August, feeding on the apple, willow (_Salix +alba_), sallow (_S. cinerea_ and _S. Caprea_), poplar (_Populus alba_ +and _P. nigra_), aspen (_P. tremula_), and the blackthorn (_Prunus +spinosa_). + +As with many other _Sphinges_, the larvæ are much more commonly seen +than the perfect insects; but the latter may often be met with resting +on tree trunks and fences in the neighbourhood of their food plants. + + +_The Poplar Hawk_ (_Smerinthus Populi_) + +[Illustration: FIG. 101.--THE POPLAR HAWK.] + +This moth is very common and very widely distributed, and may be easily +found in any of its stages. The perfect insect flies during May, June, +and July; and being rather heavy on the wing, it is easily taken with a +net as it hovers round the branches of its favourite trees or among the +flowers of gardens at dusk. The larva may be beaten from the boughs of +poplars and sallows during August and September, and during the latter +month may often be seen creeping down and around the trunks of these +trees, searching for a suitable spot in which to undergo its changes. +The pupa may be dug out of the soil at the foot of the same trees +during the autumn, winter, and spring months. + +The fore wings are ashy grey or greyish brown, marbled with darker +tints, with a conspicuous white spot near the centre. The hind wings are +similarly coloured except at the base, where there is a large patch of +brick-red. + +The caterpillar is rough, of a pale green colour dotted with yellow, +with seven oblique yellow stripes on each side. The spiracles are white, +edged with red; and the horn is yellow on the upper, and reddish on the +under side. Its chief food plants are the poplar, the Lombardy poplar +(_Populus pyramidalis_), aspen (P_. tremula_), and sallow (_Salix +Caprea_ and _S. cinerea_). + + +_The Lime Hawk_ (_Smerinthus Tiliæ_) + +This beautiful moth (fig. 5, Plate IX) is easily identified by its rich +olive green and brown wings, the fore pair of which have very +conspicuous patches of deep olive, sometimes uniting to form a +continuous central bar. It flies in May and June. + +The caterpillar is rough, of a pale green colour, dotted with yellow, +with seven oblique yellow stripes on each side. Thus it is very like the +larva of _Populi_, but may be distinguished from that species by the +orange spiracles, and by the horn, which is rough, blue above, and +yellow beneath. Behind the horn, too, there is a flat purple or violet +scale with an edging of orange. + +The food plants of this species are the lime (_Tilia vulgaris_), elm +(_Ulmus campestris_), and the hazel (_Corylus Avellana_), from which the +larvæ may be beaten in August and September, and from under these the +pupæ may be dug out during the winter months. + + +_The Humming-Bird Hawk_ (_Macroglossa Stellatarum_) + +The genus to which this insect belongs contains three interesting +British species. Their antennæ are thickened toward the end, but +terminate in a small curved bristle. Their wings are rather short and +broad; their bodies are very thick, terminating in a broad tuft of hair; +and the perfect insects fly during the daytime, delighting in the +hottest sunshine. The larvæ feed principally on low-growing plants, and +undergo their metamorphoses on the ground among the foliage. + +On Plate IX (fig. 6) one of these pretty moths is shown. It is the +Humming-bird Hawk, so called on account of its exceedingly rapid +humming-bird-like flight, accompanied by a soft humming sound. + +This insect is very common; and, being very partial to the attractions +offered by many of our favourite garden flowers, it ought to be well +known to all observers of nature. + +Take your stand near a bed of petunias or verbenas, or close to a +honeysuckle in bloom, on any hot summer's day, and you are almost sure +to be rewarded by a peep at the wonderful flight and interesting ways of +this moth. It makes its appearance so suddenly that you first view it as +an apparently motionless insect, suspended in the air, and thrusting its +long proboscis into the tube of an attractive flower. Its wings vibrate +so rapidly that they are quite invisible, and give rise to the soft hum +already mentioned. Then it darts from one flower to another, making a +similar brief stay before each while it sucks the grateful sweets. Raise +your hand as if to strike, and suddenly it vanishes you know not where. +But it is as bold as it is wary, and will often return to the selfsame +flower as if to defy your power. A sharp sweep of your net in a +horizontal direction, or a sudden downward stroke, _may_ secure it; but +if you miss it, as you probably will, it will disappear like a phantom, +and give you no opportunity of making a second attempt. + +This moth is on the wing throughout the hottest months of the year--May +to September, and will often greet you as you roam over flowery banks in +search of butterflies. + +The caterpillar feeds on the lady's bedstraw (_Galium verum_), hedge +bedstraw (_G. Mollugo_), and the goose grass (_G. Aparine_), and may be +searched for in August and September. It is rough, green or brownish, +and dotted with white. Along each side are two light lines. The horn is +thin and short, rough, and points upwards. + + +_The Broad-bordered Bee Hawk_ (_Macroglossa Fuciformis_) + +The two other moths of this genus are called Bee Hawks from their +resemblance to the humble bee. They are very much alike, but may be +distinguished by a difference in the width of the dark border of the +wings; and are named Broad-bordered and Narrow-bordered respectively. + +The former is illustrated in the woodcut appended. The fore wings are +transparent like those of bees, with a dark central spot and a broad +reddish-brown hind margin. The base and costa are black and tinged with +green. The hind wings are similarly coloured, but have no central spot. +The body is olive-brown, with a broad reddish belt, and behind are tufts +of hair, which are spread out when the insect flies, just after the +manner of the tail feathers of a bird. The moth flies in May. + +[Illustration: FIG. 102.--THE BROAD-BORDERED BEE HAWK.] + +The larva resembles that of _Stellatarum_, but exhibits a violet tint +above the legs. Its horn, too, is curved, and of a reddish or brownish +colour. It feeds on the honeysuckle (_Lonicera Periclymenum_), ragged +robin (_Lychnis Flos-cuculi_), evening campion (_L. vespertina_), red +campion (_L. diurna_), lady's bedstraw (_Galium verum_), and the field +scabious (_Scabiosa arvensis_), during the month of July. + + +Family SESIIDÆ--THE CLEARWINGS + +This family contains fourteen very pretty British insects that differ +very much from other moths in many important and interesting +particulars. + +Their antennæ, like those of the _Sphingidæ_, are thickest beyond the +middle, and those of the males are slightly _ciliated_ or hairy. Their +bodies are slender, and terminate behind in tufts of hair. The hind +wings in all cases are transparent, margined and veined with black or +brown; and the fore wings also, in most cases, have transparent bases. + +These moths delight in the hottest sunshine, and may be seen gracefully +hovering over the flowers in our gardens, looking more like gnats, bees, +and wasps, than moths. + +The larvæ of these insects are all wood-eaters, and spend their time +within the stems of shrubs and trees, eating out galleries in the +material that forms both their food and their home. Within these they +also undergo their changes, and do not expose themselves to the free air +and light till they reach their perfect stage. + + +_The Hornet Clearwing of the Poplar_ (_Trochilium Apiformis_) + +We can find space for a mention of only two of the clearwings, the first +of which is an insect that closely resembles the dreaded hornet, and +whose larva feeds in the stems of poplars--features which will account +for the above name. + +[Illustration: FIG. 103.--THE HORNET CLEARWING OF THE POPLAR.] + +The head of this species is yellow, its thorax brown with a large yellow +patch on each side, its abdomen yellow with two brown belts, and its +legs reddish orange. The front wings are transparent, with brown costæ, +and all the wings are margined with brown. + +The caterpillar, when full fed, makes a cocoon with silk and the chips +of wood that it has bitten off; and in this undergoes its metamorphoses. +It is fully grown in April, and the moth flies from the end of May to +the end of July. + +There is another 'Hornet Clearwing,' the larva of which feeds on the +stems of osiers. It may be distinguished from the species just described +by a yellow 'collar' between the head and thorax, both of which are +blackish. + + +_The Currant Clearwing_ (_Sesia Tipuliformis_) + +This is by far the commonest of all the Clearwings, and only too well +known to those who grow currants. Examine the shoots of _Ribes rubrum_ +(red currant) and _R. nigrum_ (black currant), especially those that +present a withered or half-withered appearance, and you will almost +certainly meet with signs of the presence of this intruder. Little +wriggling larvæ occupy the pithless stems throughout the winter and +spring. These are full grown in April, and in June the pretty little +moth emerges through a hole in the side of a shoot, leaving the empty +pupa case within its former home. + +[Illustration: FIG. 104.--THE CURRANT CLEARWING.] + +The fore wings of this moth have black margins, and a black transverse +bar beyond the middle. The body is black, with three pale yellow belts, +and black tufts of hair at the tip. + + +Family--ZYGÆNIDÆ + +The remaining family of the _Sphinges_--the _Zygænidæ_--includes seven +British species, three of which are known popularly as the Foresters and +the others as the Burnets. + +Their antennæ are thickest beyond the middle, but do not terminate in a +hook. Their wings are narrow and completely covered with scales. + +These moths are very sluggish creatures, spending the greater part of +their time at rest on the stems of low-growing plants. When they do fly, +their flight is short and heavy, and their pretty wings glisten in the +sunshine (for they are lovers of the sun), giving them the appearance of +bees rather than of moths. On account of this natural sluggishness, they +are exceedingly local, for they never move far from the spots where +their food plants abound, and where they had previously spent the +earlier stages of their existence. Thus we often come across a very +limited piece of ground actually alive with them, and outside which not +a single specimen is to be seen. + +The larvæ, too, are sluggish creatures, with soft and plump cylindrical +bodies and no horns. I will briefly describe three members of this +family. + + +_The Forester_ (_Ino Statices_) + +The fore wings of this species are semi-transparent, and of a beautiful +glossy green. The hind wings also are semi-transparent, but of a dull +smoky tint. The thorax and abdomen are both of a brilliant metallic +green colour. The tips of the antennæ are blunt, and the male may be +distinguished from his mate by these organs being slightly fringed or +ciliated. + +[Illustration: FIG. 105.--THE FORESTER.] + +The caterpillar is dingy grey or greenish, with a row of black spots +down the back, and a whitish stripe on each side. It feeds on the common +sorrel (_Rumex acetosa_) and the sheep sorrel (_R. acetosella_), and +when fully grown it spins a cocoon on the stem of its food plant, and +there changes to a chrysalis. + +The larva may be found during May and early June. The chrysalis state +lasts only a few days, and the moth is on the wing during June and +July. + + +_The Broad-bordered Five-spotted Burnet_ (_Zygæna Trifolii_) + +On Plate IX (fig. 7) will be found a coloured representation of this +Burnet. The two crimson spots in the base of the fore wing are very +close together, and often touch. The same remark also applies to the two +spots on the middle of the wing. A glance at the list of British Moths +(Appendix I) will show that we have also a _Narrow_-bordered +Five-spotted Burnet. This insect is very similar to the species now +under consideration, but may be identified by the narrower purplish +margin on the hind wings, and also by the shape of the antennæ, which +are not thickened so much near the end as they are in _Trifolii_. + +The larva of the present species is yellowish or greenish, with a row of +black spots on the back and a row on each side. It feeds on the +bird's-foot trefoil (_Lotus corniculatus_), hop trefoil (_Trifolium +procumbens_), and the horse-shoe vetch (_Hippocrepis comosa_) in May. +Late in May or in early June the chrysalis may be found in a silken +cocoon attached to a stem or leaf; and the perfect insect flies during +June and July. + + +_The Six-spotted Burnet_ (_Zygæna Filipendulæ_) + +So common is this moth, and so conspicuous when it flies in the blazing +sun, that it must be familiar to almost everybody. On a bright midsummer +day hundreds may often be started from their grassy beds from one little +patch of ground. + +[Illustration: FIG. 106.--THE SIX-SPOTTED BURNET.] + +[Illustration: FIG. 107.--THE LARVA OF FILIPENDULÆ.] + +The colouring of the wings is much the same as in the last species, but +there are two crimson spots instead of one near the tips of the fore +pair. + +The larvæ may be seen in vast numbers during May and June, feeding on +clovers (_Trifolium pratense_ and _T. repens_), and the bird's-foot +trefoil (_Lotus corniculatus_); and in the latter month thousands of the +chrysalides, inclosed in shuttle-shaped cocoons on grass stems, may be +seen on downs and sunny banks in almost every part of the country. + +The caterpillar, which is yellow, may be known by the two rows of black +spots that adorn each segment of the body. + + + + +CHAPTER XVIII + +_BOMBYCES_ + + +This tribe is an important one, inasmuch as it contains those few moths +whose silk is of present or anticipated commercial value. Many of the +British members, even, make silken cocoons of moderate compactness, but +none of them yield a quantity and quality of silk to justify any attempt +to utilise it in the arts. + +There are more than a hundred British species in this group, and these +represent no less than seventeen families, which exhibit a great variety +in their general appearance and habits. + + +Family--NYCTEOLIDÆ + +_The Green Silver-lined_ (_Hylophila prasinana_) + +This family, under the name of _Chloephoridæ_, is included by some +authors among the _Tortrices_ (page 298), which they somewhat resemble +in habits. It contains only four species, of which we will take one +example--the Green Silver-lined. + +[Illustration: FIG. 108.--THE GREEN SILVER-LINED.] + +The fore wings of this insect are pale green, with three oblique silvery +white lines, the middle one of which is far more distinct than the other +two. The hind wings are silvery white in the female, and yellow in the +male. It flies in May, and is common in the wooded districts of the +south-eastern counties. + +The caterpillar is pale green, dotted and striped with yellow, and has a +reddish transverse band on the second segment. It feeds on oak (_Quercus +Robur_), birch (_Betula alba_), hazel (_Corylus_ _Avellana_), beech +(_Fagus sylvatica_), and alder (_Alnus glutinosa_), from which trees it +may be beaten in July and August. + + +Family--NOLIDÆ + +_The Short-cloaked Moth_ (_Nola cucullatella_) + +We select this common moth as a representative of the small family +_Nolidæ_, which contains only five British species. These are all small +insects. They are nocturnal in their habits, and may be found at rest on +the trunks of trees during the daytime. The caterpillars are hairy, and +undergo their metamorphoses within silken cocoons. + +[Illustration: FIG. 109.--THE SHORT-CLOAKED MOTH.] + +The fore wings of _Cucullatella_ are pearly grey, with a dark patch at +the base, a triangular spot on the middle of the costal margin, and wavy +lines beyond this, parallel with the hind margin. The hind wings are +grey, and devoid of any markings. + +The caterpillar is of a brownish colour, with a line of lighter patches +down the back, and it is covered with little tufts of hair. It feeds on +the blackthorn (_Prunus spinosa_), whitethorn (_Cratægus oxyacantha_), +and also on plum trees in our gardens during the month of May. The moth +is on the wing during June and July. + + +Family--LITHOSIIDÆ + +_The Muslin Moth_ (_Nudaria mundana_) + +The family _Lithosiidæ_ contains several small moths, distinguished from +the other _Bombyces_ by the narrowness of their fore wings. When the +insects are at rest, all the wings are wrapped closely round the body. +They fly at dusk on summer evenings, but may be obtained during the +daytime by beating the boughs of trees. If an open net be held under the +boughs during this operation, the moths will generally feign death and +allow themselves to fall into it when they are disturbed. + +[Illustration: FIG. 110.--THE MUSLIN MOTH.] + +Most of the larvæ of this family feed on the lichens that cover walls +and the bark of trees, and they conceal themselves so artfully among +this peculiar vegetation that it is no easy matter to search them out; +probably many still remain unknown to entomologists. + +Our first example--the Muslin Moth--has light brownish-grey and semi +transparent wings, the front pair of which have darker markings arranged +as shown in the illustration. It is a common moth, and may be met with +in July and August. + +The caterpillar feeds on lichens in June. It is of a dull grey colour, +with a yellow stripe down the back, and has numerous little tufts of +light hair. + + +_The Common Footman_ (_Lithosia lurideola_) + +The fore wings of this species are of a leaden grey, with a bright +yellow costal stripe which dwindles to a point just before it reaches +the tip. The hind wings are very pale yellow. + +[Illustration: FIG. 111.--THE COMMON FOOTMAN.] + +The larva is black, with a reddish line on each side just above the +feet. It may be found during May and June among the lichens of oaks, +blackthorns, and firs, especially in the woods of the south of England. + +The perfect insect flies during July and August. + + +Family--EUCHELIIDÆ + +_The Cinnabar_ (_Euchelia Jacobææ_) + +The family _Eucheliidæ_ contains only four British species, two of which +must receive a share of our attention. The first of these is the +Cinnabar Moth, which is common in all localities where its food +plants--the groundsel (_Senecio vulgaris_) and the ragwort (_S. +Jacobæa_)--abound. + +[Illustration: FIG. 112.--THE LARVA OF JACOBÆÆ.] + +Its colours are so striking that a glance at its representation (fig. 1 +of Plate X) will render a written description quite unnecessary. + +The caterpillar is a very familiar and conspicuous object. Its colour is +bright orange, broken by several broad black rings; and its body is +thinly covered with hair. When fully grown (July or August) it descends +to the ground, and there changes to a smooth and shining reddish-brown +chrysalis. + +The moth appears in June or early in July. + + +_The Scarlet Tiger_ (_Callimorpha Dominula_) + +This is certainly one of the most beautiful of all our moths. Its fore +wings are dark olive green, with a lovely metallic lustre, and boldly +marked with large white and yellow spots. These spots are arranged +generally like those in the illustration, but are subject to great +variation. The hind wings are crimson, with large black patches, chiefly +distributed near the hind margin. The thorax is black, with two white +streaks; and the abdomen crimson, with a black line down the back. + +[Illustration: FIG. 113.--THE SCARLET TIGER.] + +This moth is a common one. It may be taken in June and July. I have seen +it flying somewhat freely while the sun was still shining brightly. + +The caterpillar is very dark lead colour, nearly black; and is covered +with little wart-like projections, from each of which protrudes a short +black hair. There is a broad yellow broken line down the back, and two +others on the sides. It feeds on the hound's-tongue (_Cynoglossum +officinale_) and many other low-growing plants, hybernates through the +winter, and is fully grown in May. Like the other members of this +family, it spins a light silken cocoon, in which the hairs from its body +are interwoven. + + +Family--CHELONIIDÆ + +_The Wood Tiger_ (_Nemeophila Plantaginis_) + +The _Cheloniidæ_ are popularly known as the Tigers--a title suggested by +the tiger-like colouring of some of the prominent species. They differ +from the Scarlet Tiger and the other members of the _Eucheliidæ_ in that +the males have ciliated or fringed antennæ. The larvæ, too, are more +densely covered with hair. + +The Wood Tiger (fig. 2, Plate X) is a beautiful insect, somewhat +variable in its markings, but so conspicuously coloured that our +illustration cannot fail to lead to its identification. It may be found +commonly among the undergrowth of our southern woods during May and +June. + +The caterpillar is dark brown or brownish black, covered with little +hair-bearing warts. The hairs are long and black on the foremost and +hind segments, but shorter and of a brown colour on the middle of the +body. It issues from the egg in September, feeds for a week or two on +the leaves of violets (_Viola canina_ and _V. odorata_), heartsease (_V. +tricolor_), plantain (_Plantago_), or groundsel (_Senecio vulgaris_), +and then hybernates till the following March. It is fully grown in May, +and then spins a light cocoon, with which its hairs are interwoven, +among the leaves of its food plant. + + +_The Tiger_ (_Arctia caia_) + +This splendid moth is exceedingly variable in its colour and markings, +but its usual appearance corresponds closely with that of the +illustration on Plate X (fig. 3). In some specimens the cream colour +almost entirely covers the fore wings, while in others all four of the +wings are completely covered with shades of brown. This insect is +probably known to all my readers, for it is abundant everywhere. + +The larva is as well known as the perfect insect. It is a kind of +universal feeder, partaking readily of almost every low-growing plant, +with perhaps a special partiality for dead nettles (_Lamium album_ and +_L. purpureum_). It feeds also on the lime tree (_Tilia vulgaris_), and +is commonly met with on apple trees and on the various plants of our +flower beds. The young caterpillar makes its appearance in the autumn, +and hybernates after feeding for two or three weeks only. It is full +grown in June, when it spins a silken cocoon, and changes to a shiny +black chrysalis. + +The ground colour of the larva is black, but it is covered all over with +long hairs, those down the middle of the back being grey, and the others +brown. This familiar larva is known popularly as the Woolly Bear. + + +_The Cream-spot Tiger_ (_Arctia villica_) + +There is yet another Tiger--the Cream-spot--too beautiful and too common +to be excluded from our list. It is represented on Plate X (fig. 4); +and, like the others of its genus, is so boldly marked that mistaken +identity is impossible. + +It is a very sluggish moth, more often seen at rest than on the wing, +and will suffer itself to be roughly handled without making any attempt +to escape. + +The caterpillar may be observed on sunny banks, generally feeding on +chickweed (_Stellaria media_) but sometimes on various other low-growing +weeds, including the dock and the dandelion. Its colour is black, with +red head and legs, and its body is covered with long brown hairs. It +commences to feed in the autumn, hybernates throughout the winter, and +is full grown in May, towards the end of which month it changes to a +black chrysalis within a light silken web. + +The perfect insect appears in June. + + +_The Buff Ermine_ (_Spilosoma lubricipeda_) + +The _Cheloniidæ_ also include three moths that are popularly known as +the Ermines, two of which--the Buff and the White--are exceedingly +common, and are among the constant visitors to our gardens during June +and July. + +[Illustration: FIG. 114.--THE BUFF ERMINE.] + +The Buff Ermine has all four wings of a buff or ochreous tint, and +spotted with black as here represented. + +The caterpillar is whitish, with a white line down the middle of the +back, and its body is covered with long light brown hairs. It feeds on +the dock (_Rumex_) and many other low-growing plants during August and +September, and spends the winter in the chrysalis state, lying within a +loose cocoon on the surface of the ground. + +[Illustration: FIG. 115.--THE WHITE ERMINE.] + + +_The White Ermine_ (_Spilosoma Menthastri_) + +In this species the wings are of a pale cream colour, and the dots of +the fore wings are more uniformly distributed than in the last. Its +habits and life history closely correspond with those of _Lubricipeda_, +and its larva may be found feeding on the same plants. + +This latter may be distinguished from the caterpillar of the last +species by the dark brown or black colour of the body, and the presence +of an orange line down the back. It is covered with long brown hairs. + + +Family--HEPIALIDÆ + +The five species which compose this family are known as the Swifts, a +title which they have earned by their rather rapid flight. Their wings +are narrow, and the antennæ very short. + +In the larval state they are long, naked and unsightly grubs, that live +under the surface of the ground and feed on the roots of plants. The +chrysalides are armed with short spines projecting from the segments. + + +_The Ghost Swift_ (_Hepialus Humuli_) + +One of the commonest of these moths is the Ghost Swift, which may be +seen in hundreds on waste places in the south of England during the +month of June. The wings of the male are white, with a silky gloss, and +a very narrow brown margin. The fore wings of the female are yellow, +marked with irregular reddish lines. The hind wings are of a dull smoke +colour. + +[Illustration: FIG. 116.--THE GHOST SWIFT--FEMALE.] + +The larva is pale yellow, with a brown head, and a brown horny plate on +the front of the second segment. It feeds throughout the winter on the +roots of numerous plants, including the dock, dandelion, burdock, white +dead nettle, black horehound, and the hop. + + +_The Common Swift_ (_Hepialus lupulinus_) + +The fore wings of the male of this species are brown, with a bent +whitish streak, sometimes broken, passing from the base to the middle of +the inner margin, and then to the apex. The hind wings are smoke +coloured, with a light brownish fringe. The female is much less +distinctly marked, and presents a rather dingy appearance. + +[Illustration: FIG. 117.--THE COMMON SWIFT.] + +The larva is dingy white, with brown horny plates on the second, third +and fourth segments. It feeds on the roots of dead nettles (_Lamium +album_ and _L. purpureum_), black horehound (_Ballota nigra_), and +various other herbaceous plants, throughout the winter months, and is +full grown in April. + +This insect is abundant everywhere in waste places, and may be seen on +the wing in May and June. + + +Family--COSSIDÆ + +The members of this family have longer antennæ than the _Hepialidæ_, and +the females are provided with extended ovipositors which enable them to +place their eggs in the deep crevices of the bark of trees. + +The larvæ are naked or only very slightly hairy, and have a plate on the +second segment. They feed on the wood of trees or the interior of the +stems of reeds. The pupæ have spiny projections on each segment. + + +_The Goat Moth_ (_Cossus ligniperda_) + +There are only three British species of this family, the largest of +which is the Goat Moth, so called on account of the characteristic odour +of the larva, an odour said to resemble that emitted by the goat. + +The fore wings of this fine moth are pale brown, clouded with white, and +marked by numerous wavy transverse lines. The hind wings are somewhat +similar, but of a duller tint, and the markings are less distinct. Its +average breadth from tip to tip is over three inches, and it sometimes +reaches nearly four inches. + +The larva is a most interesting creature. It is dark reddish brown on +the back, and flesh colour beneath; and its head is intensely black. It +feeds on the solid wood of the willow, poplar, oak, elm, and other +trees. The infected trees are often so riddled with the burrows of these +larvæ that they are completely destroyed, and the presence of the +intruders is frequently indicated by a heap of small chips of wood lying +on the ground near the roots. The odour of the larvæ, too, is so +powerful, that there is generally no difficulty in ascertaining their +whereabouts by it alone. + +[Illustration: FIG. 118.--THE GOAT MOTH.] + +It is not always in living trees, however, that we find these creatures, +for they often feed on rotting wood, such as the remains of old palings +and posts, that lie on the ground in damp places. + +[Illustration: Fig. 119.--THE LARVA OF LIGNIPERDA (LESS THAN HALF FULL +SIZE).] + +When fully grown they construct a strong cocoon of chips of wood, bound +together by silk, and within this they change to the chrysalis. + +The moth emerges in June or July, and is commonly found resting on the +bark of willows and poplars during the daytime. + + +_The Leopard Moth_ (_Zeuzera pyrina_) + +The wings of this species are white and semi-transparent, and marked +with numerous bluish-black spots in such a way as to remind one of the +skin of the leopard. Its body is very long, and the antennæ of the male +are doubly fringed for about half their length from the base. + +[Illustration: FIG. 120.--THE LEOPARD MOTH.] + +The caterpillar feeds on the wood of various trees--elm, apple, pear, +ash, alder, poplar, horse chestnut, birch, lilac, and several others. It +is yellowish, with black shiny spots, and a black plate on the second +segment. + +[Illustration: FIG. 121.--THE LARVA OF PYRINA (ONLY PARTLY GROWN).] + +The moth appears in July, and is widely distributed. It is attracted by +bright lights, but the best way to obtain it is to search the trunks and +branches of trees that are known to harbour the larvæ early in the +morning, and so obtain newly emerged specimens. + + +Family--LIPARIDÆ + +Passing over the two small species which are the only British +representatives of the family _Cochliopodidæ_, we come to the +interesting _Liparidæ_, the remarkable feature of which is that most of +the caterpillars are adorned with brush-like tufts of hair, and even the +chrysalides are hairy. + +The perfect insects are not brilliantly coloured, but generally display +very pale tints; and the antennæ of the males are pectinated or +feathered. + + +_The Brown Tail_ (_Porthesia chrysorrh[oe]a_) + +The family contains two moths--the Brown Tail and the Yellow Tail--that +are very similar in appearance and habits. Both have white wings, and +their bodies also are white with the exception of the tuft of coloured +hair at the tip of the abdomen, which gives the names to the species. +Their larvæ may both be found feeding on the same trees (whitethorn), +and both change to a brown hairy chrysalis within a loose cocoon among +the leaves. + +The larva of _Chrysorrh[oe]a_ is black, with four rows of little +wart-like projections on each side, from which proceed little tufts of +hairs. These hairs are reddish with the exception of one row on each +side, which is white. The tenth and eleventh segments have each a +scarlet tubercle, and there are also other small spots of the same +colour on some of the front segments. + +[Illustration: FIG. 122.--THE BROWN TAIL.] + +The larva feeds on the blackthorn in addition to the tree mentioned +above, and is full grown in June. The moth flies in August. + + +_The Gipsy_ (_Ocneria dispar_) + +The fore wings of the male are smoky brown, with darker markings, +including a V-shaped black mark near the centre. The hind wings are +brown, darker near the margin. The female is dingy yellowish white, with +darker markings arranged as in the male. The male is much inferior in +size, and its antennæ are very strongly pectinated. + +[Illustration: FIG. 123.--THE GIPSY--MALE.] + +The larva is brownish black, finely dotted with yellowish grey. There is +a grey stripe down the middle of the back, and six tubercles on each +segment give rise to tufts of long hair. It feeds on the whitethorn +(_Cratægus oxyacantha_), blackthorn (_Prunus spinosa_), and various +fruit trees. + +The caterpillar is full grown in June, and the moth appears in August. + + +_The Black Arches_ (_Psilura Monacha_) + +The fore wings of the Black Arches are white, marked with zigzag black +lines as shown in our illustration. The hind wings are smoky grey. The +hinder segments of the abdomen are banded with black and rose-pink. The +male is much smaller than the female, and has the antennæ strongly +pectinated. + +[Illustration: FIG. 124.--THE BLACK ARCHES--MALE.] + +The caterpillar is hairy, and of a greyish-white colour. A brown stripe +runs down the back. On the top of the second segment are two blue +tubercles; and there is also a tubercle, of a reddish colour, on each of +the ninth, tenth, and eleventh segments. It feeds on the oak, birch, +fir, and the apple; and is full grown in June or July. + +The moth flies during July and August. + + +_The Vapourer Moth_ (_Orgyia antiqua_) + +During the hottest summer months, and particularly in August and +September, a rather small brown moth may be seen almost everywhere, +flying rapidly and in a very erratic manner in the bright rays of the +midday sun. This is the common Vapourer Moth, which may be known at once +by its bright chestnut colour, with darker transverse markings, and a +white crescent-shaped spot in the anal angle of the fore wings. It seems +somewhat partial to civilised life, for it frequents the streets of our +metropolis, even in the very densely populated parts; and the larva is +one of the commonest of the insect forms infesting our gardens and +squares. + +[Illustration: FIG. 125.--THE VAPOURER MOTH--MALE.] + +[Illustration: FIG. 126.--THE FEMALE VAPOURER.] + +The caterpillar is variously coloured; but the prevailing tints are dark +brown, grey, and pink. On the second segment are two long tufts of hair +directed forward, and on the twelfth segment a similar tuft directed +backward. On each of the segments five to eight inclusive is a +brush-like tuft of yellowish hairs. It feeds on almost every tree +usually to be found in parks and gardens. + +When fully grown it spins a web on the bark of a tree, or on a wall or +fence, and changes to a hairy chrysalis. + +[Illustration: FIG. 127.--LARVA OF THE VAPOURER MOTH.] + +The female of this species is wingless, and never moves away from the +cocoon out of which she has crawled, but lays her eggs on the outside of +the silken web, and there remains to die. + +The clusters of eggs may be found in abundance throughout the winter +months. + + +Family--BOMBYCIDÆ + +This family contains eleven thick-bodied moths, mostly of large size, in +which the predominating colours are greys and browns. Their hind wings +are generally paler than the front pair, and less distinctly marked; and +the antennæ of the males are pectinated. + +The caterpillars are very hairy, but the hairs are uniformly +distributed, and not arranged in tufts as in the larvæ of the last +family. + +The chrysalides are inclosed in silken cocoons, but are not hairy. + +We shall briefly examine three of the members of this family. + + +_The Oak Eggar_ (_Bombyx Quercus_) + +The male of this species is shown on Plate X (fig. 5). The female is +much larger, and of a pale tawny colour. + +The ground colour of the caterpillar is black; but it is so closely +covered with short yellowish brown hairs that the black is scarcely +visible, excepting when the creature rolls itself up into a ring, which +it does when alarmed. The spiracles are white, and there is a series of +white spots down the middle of the back and along each side. It feeds on +whitethorn (_Cratægus oxyacantha_), heather (_Calluna_, _Erica_), poplar +(_Populus nigra_), and various other plants and trees. + +As a rule the larva hybernates through the winter, is full grown in the +following May, and the moth appears in July; but in Scotland the +caterpillar does not spin its cocoon till September, hybernates in the +chrysalis state, and emerges in the following June. The same is true of +the Cornish Eggars; but along the coast of South Devon both varieties +are to be met with. + +The male Eggar seems to enjoy the bright sunshine, for I have seen large +numbers flying over the rugged cliffs of the south-west throughout all +hours of the day. + + +_The Drinker_ (_Odonestis potatoria_) + +The popular name of this species is applied on account of a peculiar +feature of the larva, which sucks up the dewdrop that lies on its food +plant. + +The colour of the male is tawny and brown, with a reddish tinge; that of +the female is yellow. The front wing has an oblique dark bar passing +from the apex to the middle of the inner margin; also two white +spots--one in the middle of the wing, and the other between it and the +costal margin. + +[Illustration: FIG. 128.--THE DRINKER--MALE.] + +The caterpillar is dark bluish grey above, and has a line of orange +spots on each side. Along the spiracles are oblique orange streaks, and +a series of tufts of white hair. It feeds on the annual meadow-grass +(_Poa annua_), and several other grasses. It is a hybernator, commencing +its caterpillar state in the autumn, and reaching its full dimensions +about the end of the following May. + +The moth flies during July and August. + + +_The Lappet_ (_Lasiocampa quercifolia_) + +Our last example of the _Bombycidæ_ is the Lappet (Plate X, fig. 6), a +large moth, the female often measuring considerably over three inches +from tip to tip. The wings are of a rich reddish brown, and exhibit a +beautiful purplish bloom in a newly emerged insect. Scalloped black +lines pass transversely across each wing, and a small black dot lies +near the centre of the fore wings. + +The caterpillar is very variable in colour, but is usually grey or +reddish brown. A deep purple band lies between the second and third +segments, and another between the third and fourth. On the twelfth there +is a small hump, and a pale stripe, more or less distinct, runs along +each side. It feeds on the blackthorn (_Prunus spinosa_), buckthorn +(_Rhamnus catharticus_), and the white willow (_Salix alba_). + +The moth is not uncommon, and is on the wing in June. + + +Family--ENDROMIDÆ + +_The Kentish Glory_ (_Endromis versicolor_) + +The beautiful Kentish Glory is the only British representative of its +family. The male is shown in Plate X (fig. 7); the female is larger and +similarly marked, but its colours are not so bright. + +This moth is not common, but may be seen occasionally in the birch woods +of the southern counties. The males fly rapidly in the bright sunshine, +but the females must be searched for on the bark and branches of the +trees. + +The eggs are laid in April on the twigs of the birch (_Betula alba_), +and the young caterpillar emerges early in May. It is gregarious at +first, but loses its social tendencies as it gets older. When full +grown, it is of a pale green colour, with white spiracles, a dark green +line down the back, and an oblique white stripe on each side of each +segment. The sides are dotted with black and brown, and there is a +conspicuous hump on the top of the twelfth segment. + +When fully grown it spins a cocoon among the dead leaves beneath the +tree, and in this it spends the winter months in the chrysalis state. + + +Family--SATURNIIDÆ + +_The Emperor Moth_ (_Saturnia pavonia_) + +Here is another family with but one British member; but in this, as in +the last case, the only representative is a really beautiful insect. The +male _Pavonia_ is shown on Plate X (fig. 8), and will need no written +description as an aid to its identification. The female is larger, and +similarly marked, but the ground colour of the wings is pale grey. + +This moth is abundant almost everywhere, and may be looked for in the +neighbourhood of heaths and woods early in the month of May. + +The larva feeds on a large number of plants and trees, among which may +be mentioned the willow (_Salix alba_), blackthorn (_Prunus spinosa_), +elder (_Sambucus nigra_), whitethorn (_Cratægus oxyacantha_), bramble +(_Rubus fruticosus_), heaths (_Erica tetralix_ and _E. cinerea_), and +the meadow-sweet (_Spiræa ulmaria_). Its colour is a lovely green; and +each segment has several pink tubercles, each surrounded by a black +ring, and giving rise to a tuft of short black hairs. The spiracles are +orange. + +In the autumn it spins a pear-shaped cocoon of silk, open at the small +end (fig. 28). + +It may here be mentioned in passing that, in the case of some of the +larger moths of the few preceding families, the young entomologist is +likely to meet with larvæ more frequently than the perfect insect. These +moths, however, are mostly very hardy and easily reared; and a beginner +cannot do better than endeavour to obtain either ova or larvæ, in order +that he may be able to watch the different species through their various +stages. + + +Family--DREPANULIDÆ + +We now reach a family containing six small moths that differ in many +important particulars from those we have just been considering. They are +of such slender build that a beginner may easily mistake them for +Geometers. Their wings, though small, are broad, and well proportioned +to their bodies. In five cases out of the six the front wings are more +or less hooked at the tips, and on this account the moths in question +are called the Hook Tips. + +The larvæ are not hairy, but they all have little fleshy projections on +their backs. Their bodies also taper to a point behind, and the last +pair of claspers are wanting, so that they have only fourteen walking +appendages. When at rest they usually fix themselves by their claspers +only, their pointed 'tails' being directed slightly upward, and all the +front segments being also elevated. When about to change, they descend +to the ground, and spin their cocoons among dead leaves. + +Two only of this family can receive an individual notice. + + +_The Oak Hook Tip_ (_Drepana binaria_) + +This can hardly be described as a very common moth, but it is fairly +plentiful in the woods of the southern counties of England. + +Its wings are yellowish brown, marked with two lighter transverse lines. +There are two black spots between the lines of the fore wings. The +antennæ of the male are pectinated; those of the female simple. The +latter sex is further distinguished by the paler colour of the hind +wings. + +[Illustration: FIG. 129.--THE OAK HOOK TIP.] + +The larva is brown, with a broad stripe, edged with yellow, down the +back. There are two projections on the back of the fourth segment. It +feeds on oak (_Quercus Robur_) and birch (_Betula alba_). + +This moth is double-brooded, and may be seen on the wing in June and +August. The larva may be beaten from the above-mentioned trees in June +and July, and again in September. + + +_The Chinese Character_ (_Cilix glaucata_) + +The fore wings of this species are white, with a broad dark blotch from +the inner margin to near the costa. The central portion of this blotch +is marked with silvery spots which are said to resemble Chinese +characters. The hind margin is shaded with a dark grey border, inside +which is a row of dark spots. The hind wings are clouded with grey. + +[Illustration: FIG. 130.--THE CHINESE CHARACTER.] + +This moth is widely distributed, and seems to be common throughout +England. It is double brooded, the first brood appearing in May and +June, and the second in August. + +The caterpillar, which is brown, with two prominent tubercles on each of +the third and fourth segments, feeds on the whitethorn (_Cratægus +oxyacantha_), and the blackthorn (_Prunus spinosa_). + + +Family--DICRANURIDÆ + +The five British species that represent this family are such interesting +insects that we should like to have given a detailed description of all +of them, but our limited space will allow of no more than an outline of +the general characteristics of the group and a selection of two for +individual mention. + +They are thick-bodied moths, and the prevailing colours are white and +shades of grey. The antennæ are pectinated in the males, and, with the +exception of the Lobster Moth (_Fagi_), in the females also. + +The larvæ, like those of the last family, have no anal claspers, and +stand, when at rest, with both ends of the body raised. They have two +'tails' projecting from the last segment. The largest of them (the +Puss), and three smaller species (Kittens) that closely resemble it in +habits, all construct hard cocoons to be presently described; but the +larva of the Lobster Moth spins a light cocoon among the leaves of +trees. + +They all spend the winter in the chrysalis state. + + +_The Poplar Kitten_ (_Dicranura bifida_) + +Our illustration shows the arrangement of the white and grey on the +wings of this moth, but the other Kittens (_Bicuspis_ and _Furcula_) so +closely resemble it that it is necessary to point out a mark of +distinction. It will be observed that the fore wings are crossed by a +broad grey band, edged with black. This band, in the present species, is +almost of the same width throughout, its interior margin being almost +straight, and the exterior one slightly concave. In _Furcula_, the outer +margin of the band is generally sharply bent inward just below the +costa. In _Bicuspis_ the grey band varies considerably in shape, but +both this and the dark blotch near the tip of the wing are more sharply +defined than in the other two species. + +[Illustration: FIG. 131.--THE POPLAR KITTEN.] + +The caterpillar is green, dotted with brown, and has a brown stripe on +the back. This stripe is broken on the third segment, and widens out on +the eighth and thirteenth segments. It feeds on the Poplar (_Populus +nigra_) and Aspen (_P. tremula_). + +When full grown it descends to the trunk of the tree, and constructs a +very hard cocoon of a glutinous substance from its own body mingled with +little pieces of the bark that it removes for the purpose. Thus made, +the cocoon so closely resembles the surrounding bark that detection is +very difficult. I have frequently found these cocoons on the inner +surface of loose bark. + +This moth is widely distributed, and may be searched for in June and +July. The larva feeds during August and September. + + +_The Puss_ (_Dicranura vinula_) + +No written description is necessary in this case, the illustration +easily serving for identification. This beautiful moth flies in May and +June, and is common everywhere. + +[Illustration: FIG. 132.--THE PUSS MOTH.] + +The caterpillar is a very interesting creature. It is green, with a hump +on the fourth segment, and a patch of brown from the fourth segment to +the tail. This patch is very wide on the eighth segment, but tapers to a +point on the thirteenth. The two horns are rather long and rough, and +from each of them a very slender pink filament is protruded when the +caterpillar is irritated. + +It constructs a cocoon very similar to that of _Bifida_, though of +course larger, on the bark of the tree on which it fed, generally three +or four feet from the ground. It feeds on sallows, willows, and poplars, +and may be found during July and August. + + +Family--NOTODONTIDÆ + +_The Coxcomb Prominent_ (_Lophopteryx camelina_) + +The family _Notodontidæ_ contains several moths of somewhat varied +appearance, but foremost among them are the 'Prominents,' distinguished +by a conspicuous projection on the inner margin of the fore wings. + +[Illustration: FIG. 133.--THE COXCOMB PROMINENT.] + +Our example of this group is the Coxcomb Prominent. + +Its fore wings are brown, with darker markings arranged as shown in the +illustration; and the hind margins are scalloped. The hind wings are +much paler, with a dark brown patch in the anal angle. + +The caterpillar is green, with a yellowish line on each side. The +spiracles are black, and there are two small humps on the twelfth +segment. It feeds during August, September, and October, on various +trees, including the oak, birch, poplar, hazel, and alder. + +The moth flies from June to August, and is moderately common and widely +distributed. + + +Family--PYGÆRIDÆ + +_The Buff Tip_ (_Phalera bucephala_) + +The first of our two examples of this small family is the common and +destructive Buff Tip. The perfect insect is represented on Plate X, fig. +9, and is too well known to require a lengthy description. During June +and July it may be seen resting on the bark of trees almost everywhere, +with its wings folded closely round its body, and its antennæ tucked +under the wings, looking just like a piece of stick, or a projection of +the bark on which it sits. + +[Illustration: FIG. 134.--THE LARVA OF BUCEPHALA.] + +The caterpillars appear towards the end of June, and may be seen in +dense clusters on lime and other trees, sometimes twenty or thirty +huddled together on a single leaf. As they grow larger they retain their +gregarious tendencies, and often completely strip the leaves from large +branches. They are of a dull yellow colour, hairy, and have seven broken +black lines, one along the middle of the back, and three on each side. +The head and legs are black. + +When full grown, they descend to the root of the tree, burrow into the +soil, and there remain in the chrysalis state till the following June. +The chief food plants of this species are the lime (_Tilia vulgaris_), +elm (_Ulmus campestris_), and hazel (_Corylus Avellana_). + + +_The Chocolate Tip_ (_Pygæra curtula_) + +This species is not nearly so common as the last, but is to be met with +more or less in most of the English counties in the month of May. + +Its fore wings are light greyish brown, crossed with four transverse +paler streaks, and tipped with a patch of chocolate brown. The hind +wings are pale yellowish grey. + +[Illustration: FIG. 135.--THE CHOCOLATE TIP.] + +The young caterpillars feed in companies between leaves which they have +spun together, but when nearly full grown they cease to be gregarious. +They are also very different in appearance at different ages. When fully +fed, the larva is of a reddish-grey colour, spotted with black, with a +double row of orange-coloured warts on each side. There is also a little +black hump on each of the fifth and twelfth segments. + +The food plants of this species are sallows (_Salix caprea_ and _S. +cinerea_), poplar (_Populus nigra_), and aspen (_P. tremula_). + + +Family--CYMATOPHORIDÆ + +This, the last family of the _Bombyces_, contains seven species of +moderate size, the larvæ of which are either quite smooth or have small +warty prominences. The seven species are grouped into three genera, from +two of which we shall select a representative. + + +_The Peach Blossom_ (_Thyatira Batis_) + +The popular name of this pretty little moth is given on account of the +resemblance of the pink patches of its olive-brown fore wings to the +petals of the peach flower. It is a moderately common moth, widely +distributed in England and Ireland, and flies during June and July. + +[Illustration: FIG. 136.--THE PEACH BLOSSOM.] + +The caterpillar is marbled with reddish grey and brown, and has a hump +on the third segment, and a smaller prominence on each of the segments +six to ten inclusive. It feeds on the bramble (_Rubus fruticosus_) +during August and September, and spends the winter in the chrysalis +state, inclosed in a loose cocoon among the dead leaves at the root of +its food plant. + + +_The Yellow-horned_ (_Asphalia flavicornis_) + +This is one of the earliest of our moths, appearing on the wing in +March, when it may be attracted by means of sugar placed on the bark of +the birch (_Betula alba_). + +[Illustration: FIG. 137.--THE YELLOW-HORNED.] + +The wings are grey, with a decidedly greenish tinge, crossed by three +dark lines near the base, and two others, which are zigzag, just outside +the centre. Between these two sets of lines is a conspicuous round pale +spot. The hind wings are greyish brown, darker along the hind margin. + +The larva, which feeds on the above-named tree, is pale greenish, with +both white and black dots. It rolls itself up in a leaf, and seldom +ventures out of the retreat thus formed. It is fully fed in July or +August. + + + + +CHAPTER XIX + +_THE NOCTUÆ_ + + +We have already noticed that several of our moths fly by day; that some +come out of their hiding places at dusk, and settle down again to rest +before the deepest shadows of night fall; and that others prefer the +darkest hours of the night. The tribe of moths we are next to consider +includes the greater number (about three hundred) of our truly nocturnal +species, hence the name that heads this chapter. + +They are generally of a somewhat dingy appearance, the prevailing +colours being dull shades of grey, drab, and brown. So closely, in fact, +do certain of them resemble each other, that the greatest care has to be +exercised in the identification of species--a task that is rendered +still more difficult by the variations that we observe in the tints and +markings of certain species. + +These moths have generally rather stout bodies. Their fore wings are +somewhat narrow, and, when the insects are at rest, these are brought +close to the body, and the hind pair are folded up beneath them. + + +Family--BRYOPHILIDÆ + +_The Marbled Beauty_ (_Bryophila Perla_) + +Our first family--the _Bryophilidæ_--contains only four British species. +These are small and slender-bodied moths, whose larvæ feed in early +morning on the lichens that cover stones and old walls, and conceal +themselves by day in holes and chinks and under stones. + +The Marbled Beauty is the only moth of this family that may be +described as common with us. It is abundant in nearly every English +county, as well as in parts of Scotland and Ireland. + +[Illustration: FIG. 138.--THE MARBLED BEAUTY.] + +Its wings are very pale grey, marked with a darker bluish grey, as shown +in the engraving. These markings are variable, but the bases of the fore +wings have always a dark blotch, followed by a patch of pale grey or +white, extending the whole width of the wing. The moth may be found from +the beginning of July to the middle of September. + +The larva feeds from February to April. It is black above, with a broad +orange-bordered stripe down the back; and its body is covered with small +warts, each of which bears a single hair. + + +Family--BOMBYCOIDÆ + +In this family there are sixteen British moths, several of which are +exceedingly common. They are much larger than the _Bryophilidæ_, and of +a much stouter build. The larvæ are covered with little hair-bearing +warts, and are, indeed, often so hairy that they may be mistaken for the +caterpillars of the _Bombyces_. + + +_The Grey Dagger_ (_Acronycta Psi_) + +This is the commonest of all the _Bombycoidæ_. It may be found at rest +on tree trunks and palings during the daytime throughout the summer. Its +fore wings are pale grey, with four conspicuous black marks, one of +which--that in the anal angle--resembles the Greek letter _psi_ ([psi]) +placed sideways. + +[Illustration: FIG. 139.--THE GREY DAGGER.] + +The larva is black or very dark grey, with a pale yellow line down the +back, and a black hump on each of the fifth and twelfth segments, that +on the fifth being much larger than the other. It feeds in the autumn on +lime (_Tilia vulgaris_), blackthorn (_Prunus spinosa_), whitethorn +(_Cratægus oxyacantha_), fruit trees, and various other trees, shrubs, +and herbs. + +The moth called the Dark Dagger (_Tridens_) is hardly to be +distinguished from _Psi_. It is not really any darker, and its markings +are almost exactly similar; but the larva is very different. + + +_The Poplar Grey_ (_Acronycta megacephala_) + +This is also a very common moth, to be found in all the southern and +midland counties, wherever poplars abound, during June and July. + +[Illustration: FIG. 140.--THE POPLAR GREY.] + +Its fore wings are grey, marbled with a very dark grey. A little inside +the middle of these wings, near the costa, is a round spot with a dark +centre. This spot is represented in a large number of the _Noctuæ_, and +is known as the _orbicular_. It will be observed that in the present +species it is very distinct. + +The caterpillar is dark grey, with a line of black dots down the back; +and it has a number of little warts, bearing hairs. On the back of the +eleventh segment is a rather large pale spot. It feeds during August on +various species of poplar, and changes to a chrysalis in a crevice of +the bark. + + +_The Figure of Eight_ (_Diloba cæruleocephala_) + +The fore wings are brownish grey. Near the middle of the wing, but +nearer the costa than the inner margin, are two whitish spots that +resemble the figure 8. The hind wings are dull brownish grey, with +darker wing rays, and a dark spot near the centre. + +[Illustration: FIG. 141.--THE FIGURE OF EIGHT.] + +This moth is common in all parts, and flies during September. + +The caterpillar emerges from the egg in spring, and is fully grown in +May or June. It is of a very pale colour--yellowish or greenish--with a +broad and broken yellow stripe down the back, and a bluish or greenish +stripe on each side. Its head is blue (hence the specific name) with two +black spots. It feeds on the hawthorn (_Cratægus oxyacantha_) and +various fruit trees; and on the twigs of these (especially the hawthorn) +the little clusters of eggs may be seen during the winter. + + +Family--LEUCANIIDÆ + +In this family we have a number of rather small moths, with, generally, +no markings on their wings, save, perhaps, a few dots or streaks. + +Their larvæ feed principally on grasses and reeds, and change to the +chrysalis state either in a cocoon among the food plants, or under the +surface of the ground. + +Several of these insects are very common, and most of them abound in +fens and marshes. + + +_The Brown-line Bright-eye_ (_Leucania conigera_) + +The fore wings are yellowish brown. The 'brown line' is a transverse +line parallel with the hind margin, and distant from it about one-fourth +the length of the wing. Another dark brown line, describing a sharp +bend, passes across the wing near the base. The 'bright eye' is a light +spot just outside the centre of the wing, nearer the costa than the +inner margin. This is another of those marks that occur very constantly +in the wings of the _Noctuæ_. It lies beyond the _orbicular_ spot, and +is usually somewhat kidney-shaped, and is consequently named the +_reniform_. + +[Illustration: FIG. 142.--THE BROWN-LINE BRIGHT-EYE.] + +The caterpillar is yellowish or greyish, with a pale dorsal line edged +with black. On each side of this is a broad black line, below which is a +yellow line edged with black, then a whitish stripe, next a yellow line +edged with black on the upper side, and lastly a broad brownish line, +just above the spiracles, edged with black on both sides. It feeds on +couch grass (_Agropyron repens_) and various other grasses, and is fully +grown in May. + +The moth flies in July and August, and is common throughout the United +Kingdom. + + +_The Smoky Wainscot_ (_Leucania impura_) + +This same genus includes a number of moths, very similar in general +appearance, and popularly known as the 'Wainscots.' Of these we shall +take two examples. + +The first is the Smoky Wainscot, so called from the dark smoky tint of +the hind wings. Its fore wings are wainscot brown, with lighter rays; +and they each have three black dots arranged in the form of a triangle, +one in the centre, and the other two between this and the hind margin. + +[Illustration: FIG. 143.--THE SMOKY WAINSCOT.] + +The caterpillar is yellowish, with a fine white line down the back. The +spiracles are red, and inclosed in black rings. It feeds on sedges +(_Carex_) from March to May. + +The moth is on the wing from June to August. + + +_The Common Wainscot_ (_Leucania pallens_) + +This moth is very much like the last. The fore wings exhibit the same +three dots, but it may be distinguished by the pale colour of the hind +wings. + +[Illustration: FIG. 144.--THE COMMON WAINSCOT.] + +The larva feeds on various grasses in March and April. It is of a +pinkish grey colour, with two rows of black dots on each side of the +dorsal line. There are also three stripes along the side, two of which +are brownish and the other grey. + +The moth is common everywhere from June to August. + + +_The Bullrush_ (_Nonagria arundinis_) + +Our last example of this family is the Bullrush, a moth that is common +in all parts where its food plant abounds. + +It is much larger than the two preceding species. The fore wings are +yellowish brown, with three parallel transverse lines of black spots. +The hind wings are whitish, tinged with brown near the hind margin. + +[Illustration: FIG. 145.--THE BULLRUSH.] + +The caterpillar is of a dull pinkish colour, with a shining brownish +plate on the second segment. The spiracles are black. It feeds inside +the stems of the reed-mace (_Typha latifolia_), and changes to a +chrysalis within the gallery it has excavated, after making a hole +through which it can escape when it attains the perfect form. + +The caterpillar may be found in May and June, the chrysalis in August, +and the moth in September. + + +Family--APAMEIDÆ + +This large family contains no less than forty-four British species, many +of which are exceedingly common; and of the others only about half a +dozen can be regarded as rare. + +Most of them are of medium size, and with one or two exceptions are +dressed in rather dingy garbs; but, although the ground colours are +dull, the various markings of the wings are sharply defined. They may be +searched for on palings and the bark of trees by day, at which time they +repose with their wings sloping like the sides of the roof of a house. +Some are easily attracted by lights, and others partake freely of the +entomologist's 'sugar.' + +The larvæ have small retractile heads, and feed on low-growing plants, +keeping themselves well concealed on the lower leaves close to the +ground. + + +_The Frosted Orange_ (_Gortyna Ochracea_) + +We commence with one of the brightest members of the family, the Frosted +Orange. Its fore wings are dark yellow or ochreous, with distinct brown +markings, the chief of which are two broad transverse bands. The +orbicular spot is pale yellow and very distinct. The hind wings are +dingy yellow. This moth flies from July to September, and is easily +attracted by a light at night. It is common everywhere. + +[Illustration: FIG. 146.--THE FROSTED ORANGE.] + +The larva is yellow, dotted with black, with a brownish plate on the +second segment. It feeds inside the stems of a number of plants, +including the marsh thistle (_Cnicus palustris_), musk thistle (_Carduus +nutans_), burdock (_Arctium minus_), mullein (_Verbascum thapsus_), +foxglove (_Digitalis purpurea_), and elder (_Sambucus nigra_). When +about to change to the chrysalis it eats _nearly_ to the surface of the +stem, leaving only a very thin and transparent layer of the epidermis to +cover the hole through which it is to escape when it becomes a moth. + +The caterpillars are to be found in June, and the chrysalides in July. + + +_The Flame_ (_Axylia putris_) + +This also is a pretty insect, but much smaller than _Ochracea_. It is +common in most parts, and may be seen flying in weedy and waste grounds +at dusk during June and July. + +[Illustration: FIG. 147.--THE FLAME.] + +The fore wings are pale pinkish brown, with dark brown along the costa, +and two patches of the same colour on the hind margin. There is also a +double line of small brown dots parallel with the hind margin. + +The larva is brown, with one yellow and two white dots on each segment. +There is also a triangular dark patch on each of the fifth and sixth +segments. It feeds during August on the stinging nettle (_Urtica +dioica_), and various other low herbs. + + +_The Light Arches_ (_Xylophasia lithoxylea_) + +The fore wings of this species are very light ochreous, with a light +brown patch on the middle of the costa, and patches of the same colour +along the hind margin; also a row of small black dots parallel with the +same margin. The hind wings are pale ochreous: they are brownish along +the hind margin, and have a light fringe. + +[Illustration: FIG. 148.--THE LIGHT ARCHES.] + +The moth is very common in waste places, and flies in June and July. + +The caterpillar is of a dirty white colour, dotted with black, and has a +black head. It feeds on the roots of grasses in May. + + +_The Flounced Rustic_ (_Luperina testacea_) + +The fore wings are greyish brown, with darker umber-brown markings. +These latter are variable, but the most conspicuous is a series of dark +crescent-shaped spots almost parallel with the hind margin, and +immediately outside these is a series of paler crescents. + +[Illustration: FIG. 149.--THE FLOUNCED RUSTIC.] + +The caterpillar is dull flesh-colour, with a brown head, and a brownish +plate on the second segment. It feeds on the stems of grasses. + +The moth is common throughout the British Isles, and flies in August and +September. + + +_The Cabbage Moth_ (_Mamestra Brassicæ_) + +Whatever be your methods of moth collecting, you are sure to meet with +_Brassicæ_ in abundance. They swarm round the insect hunter's sugar in +such numbers as to become a positive nuisance. They are also attracted +by light. During the day they may be seen at rest on palings. The +caterpillar is even better known, and with reason, for it is fearfully +destructive to our vegetables and even our flower beds. It burrows into +the hearts of cabbages, filling the galleries it makes with its +excrement, often leaving no very visible outward signs of its presence +within. But its ravages are by no means confined to cabbages. It eats +with more or less relish almost every vegetable and flowering plant of +our gardens, and is equally partial to the various herbs of the field. + +[Illustration: FIG. 150.--THE CABBAGE MOTH.] + +The fore wings of the moth are dingy brownish grey, marbled in a very +confused manner by darker markings. The _reniform_ spot is very +distinct, the orbicular less so. A light zigzag line runs parallel with +the hind margin. It flies in June and July. + +The larva feeds later in the season, and changes to the chrysalis +beneath the soil in the autumn. It is of a dark grey colour, with a +darker line on the back, and a lighter one along the spiracles, which +are white. + + +_The Dot_ (_Mamestra Persicariæ_) + +The conspicuous white reniform spot on the very dark marbled fore wings +is always sufficient for the identification of this species. + +This moth is out in June and July; and during the latter month lays its +eggs on the elder (_Sambucus nigra_), and the various low plants that +supply the larva with food. + +[Illustration: FIG. 151.--THE DOT.] + +The larva is greenish or greyish, sometimes with a reddish tinge, with a +light line down the back. The twelfth segment is humped, and there are +dark V-shaped marks on the back of segments five to twelve inclusive. It +is full grown in September, and burrows into the ground to undergo its +change to the chrysalis, in which state it remains throughout the +winter. + + +_The Rustic Shoulder-knot_ (_Apamea basilinea_) + +The fore wings of this species are pale ochreous grey, with light brown +markings; and there is a short dark streak in the middle of the base, +from which feature the specific name (_Basilinea_) is derived. The hind +wings are of a similar colour, but shading into a dark smoke colour at +the hind margin. + +[Illustration: FIG. 152.--THE RUSTIC SHOULDER KNOT.] + +The caterpillars feed at first on the grains of wheat, on the ears of +which the moth deposits the eggs in June. At harvest time they remain +hidden among the husks, and are often threshed out in large numbers by +the blows of the flail. The cold weather soon overtakes them, and they +then spin a cocoon in which to pass the winter. On the approach of +spring they come out again, and feed by night on various low plants, +hiding themselves among the roots by day. In March they are full grown, +and change to brown chrysalides beneath the surface of the ground. + +The moth flies in June, and is one of the commonest and most destructive +of our _Noctuæ_. + + +_The Marbled Minor_ (_Miana strigilis_) + +The next three genera (_Miana_, _Phothedes_, and _Celæna_) include seven +small moths known as the 'Minors.' The commonest of them is the Marbled +Minor, which is to be found in abundance everywhere during June and +July. + +[Illustration: FIG. 153.--THE MARBLED MINOR.] + +This species is very variable, but the fore wings are usually dark +brown, marbled with a lighter colour--white or grey. There is generally +an irregular white or pale grey band crossing the wings parallel with +the hind margin, and two white marks on the inner margin, halfway +between this band and the base. There is also a deep black blotch across +the middle of the wing. + +The caterpillar is greyish or greenish with paler lines and black +spiracles. It feeds on grasses in March and April, and changes to a +chrysalis under the ground in May. + + +Family--CARADRINIDÆ + +There are only ten British species in this family, two of which are +rare; and most of the others are particularly dingy. The transverse +lines so often seen on the fore wings of Noctuæ are generally well +marked. The larvæ have short stiff bristles, and feed on low plants; +they undergo their changes in an earthen cocoon under the ground. + + +_The Mottled Rustic_ (_Caradrina Morpheus_) + +We select as our type of this family the Mottled Rustic--a common moth +that may be procured from June to August. Its fore wings are brownish +grey, with darker lines and spots; the hind wings are almost white, but +darker at the tip. + +[Illustration: FIG. 154.--THE MOTTLED RUSTIC.] + +The caterpillar is brownish grey, with a row of triangular spots on each +side of the back. It is very sluggish, spending the greater part of its +existence among the roots of low plants. It feeds throughout the winter, +except during severe weather, and is full grown in April. The food +plants include teasels (_Dipsacus pilosus_ and _D. sylvestris_), hedge +bedstraw (_Galium Mollugo_), orpine (_Sedum Telephium_), sallows +(_Salix_), and various other plants. + +The chrysalis may be dug out in May. + + +Family--NOCTUIDÆ + +A glance at our list of British _Noctuæ_ (Appendix I) will show that +this family contains nearly fifty species and only three genera. It +includes several very common moths that frequent our gardens and are to +be met with during almost every summer evening ramble. + +Most of the species are very dingy, but the half-dozen that comprise the +genus _Triphæna_ are characterised by the bright colouring of the hind +wings. The fore wings are narrow and more or less glossy, and overlap to +a greater or less extent when the insects are at rest; and the hind +wings are folded and completely hidden beneath them. + +The larvæ are rather thick and smooth, and generally of very dingy +colours. They feed on low plants, often confining their ravages to the +roots, and generally lie well concealed close to the ground or under the +surface. + +The pupæ are brown, smooth, and shining, and are usually inclosed in +earthen cocoons. + +We shall briefly notice a few members of each of the three genera. + + +_The Turnip Moth_ (_Agrotis Segetum_) + +This is another of those destructive insects that attack vegetable and +flower gardens, often doing so much damage to our crops as to become +quite a nuisance to cultivators. + +The moth is decidedly dingy. Its fore wings are brown, clouded with a +darker tint. The hind wings are almost white, sometimes with a brown +hind margin. + +[Illustration: FIG. 155.--THE TURNIP MOTH.] + +In June it lays its eggs on the stems of young plants, generally very +close to the ground. As soon as the young caterpillars emerge they +commence feeding on the lower parts of the stems, or burrowing deeply +into the larger succulent roots. When the larvæ have completed their +work of destruction in this way, they change to brown chrysalides in the +ground. Some undergo this change in October, and shortly after give rise +to a second brood of moths; but most of them remain in the caterpillar +state throughout the winter, and, contrary to the general rule with +hybernating larvæ, continue to feed almost throughout the winter months, +and change to the chrysalis in the following May. + +The caterpillar grows to a large size. It is of a greyish or greenish +colour, with a paler line on the back, a light brown line on each side +of this, black spots between these lines, and black spiracles. + + +_The Heart and Dart_ (_Agrotis Exclamationis_) + +The destructive work of _Segetum_ is assisted by similar operations of +the Heart and Dart, the larva of which feeds voraciously on the roots of +several of our cultivated vegetables, though the present species does +not entirely confine its ravages to the farmer's crops, but attacks the +roots of many low-growing herbs. + +The fore wings of the moth are light brown, generally with a reddish +tinge. The darker markings include a large and very distinct reniform +spot, a less distinct orbicular, and a conspicuous longitudinal blackish +streak near the base of the wing known as the _claviform_. Beyond the +reniform a curved and zigzag dark line crosses the wing. The hind wings +of the male are very pale, those of the female darker, with a whitish +fringe. + +[Illustration: FIG. 156.--THE HEART AND DART.] + +The moth flies from June to August, and is common everywhere. The +caterpillar feeds in the autumn, and reaches its full size in October; +but it is said to feed at intervals throughout the winter. Its colour is +dingy brown or grey, with paler lines on the sides. The spiracles are +black, and there are black dots on the sides. + + +_The Garden Dart_ (_Agrotis nigricans_) + +This is another dingy moth, whose general appearance is so unattractive +that the tyro might be inclined to neglect it. But it must not be +omitted from our selection on that score, for our main object here is to +give the beginner an acquaintance with those species that are most +likely to be captured in the earlier part of his career, and this moth +is certainly one of those that may be described as 'abundant +everywhere.' + +[Illustration: FIG. 157.--THE GARDEN DART.] + +Its fore wings are dull dark brown, often tinged with red, and clouded +with black. The reniform spot is pale, the orbicular spot less distinct, +and between the two there is generally a rhomboidal dark spot. There is +also a short dark streak near the base of the wing, and a black spot +before the orbicular. The hind wings are pale, but smoky towards the +hind margin. + +The caterpillar is brown and shining, with a fine pale line on the back, +and a double white stripe below the spiracles. It is also dotted with +black. It is exceedingly destructive, feeding on clovers (_Trifolium +pratense_ and _T. repens_) and various low plants in May and June. + +The moth flies from June to August. + + +_The Flame Shoulder_ (_Noctua plecta_) + +As our example of the next genus we take the Flame Shoulder, a rather +small moth, easily identified by the broad yellowish-white streak along +the costa of the reddish-brown fore wings. The orbicular and reniform +spots are margined with white, and a thin white streak runs from the +base of the wing to the former. The hind wings are white. This moth +flies in July, and is common throughout Great Britain. + +[Illustration: FIG. 158.--THE FLAME SHOULDER.] + +The caterpillar is reddish brown, with a slender line of white dots on +the back, and a similar line on each side. The body is smooth and +velvety, and is netted and dotted all over with dark brown. It feeds on +the lady's bedstraw (_Galium verum_), sweet woodruff (_Asperula +odorata_), and many other low plants; and is full fed early in July. + + +_The Lesser Broad Border_ (_Triphæna ianthina_) + +We now come to the third and last genus (_Triphæna_) of this extensive +family, a genus which includes six interesting moths, with bright orange +or yellow hind wings. Of these we shall take three examples. + +[Illustration: FIG. 159.--THE LESSER BROAD BORDER.] + +The first of them--the Lesser Broad Border--has fore wings of a rich +reddish or violet brown, with paler markings. The hind wings are bright +orange, with a broad marginal band of black. + +It is a common moth, particularly in the south-western counties, and +flies during July and August. + +The caterpillar is of a dingy yellowish or greenish grey, with a light +line down the back, and two black spots on each side of segments nine to +twelve inclusive. It feeds throughout the winter by night on dead +nettles (_Lamium purpureum_ and _L. album_), primrose (_Primula +acaulis_), whitethorn (_Cratægus oxyacantha_), blackthorn (_Prunus +spinosa_), and various low plants; and may sometimes be seen in flower +gardens. It is full grown in April. + + +_The Lesser Yellow Underwing_ (_Triphæna Comes_) + +This insect is very similar to the last, but is larger. The fore wings +are also of a greyish or ochreous brown, and the black margin of the +hind wings is proportionately narrower. + +[Illustration: FIG. 160.--THE LESSER YELLOW UNDERWING.] + +It is more abundant than _Ianthina_; in fact it is to be found +everywhere in plenty during the month of July. + +The caterpillar is yellowish brown. On the back of each of the eleventh +and twelfth segments are two conspicuous dark marks. The spiracles are +white, and below them is a pale brown stripe. It feeds on the foxglove +(_Digitalis purpurea_), chickweed (_Stellaria media_), thrift (_Armeria +maritima_), and other low plants in the autumn, hybernates during the +winter, and attacks sallows (_Salix Caprea_ and _S. cinerea_) and +whitethorn (_Cratægus oxyacantha_) as soon as the buds appear in the +spring. It is full grown in April, and then changes to a chrysalis on +the surface of the earth. + + +_The Large Yellow Underwing_ (_Triphæna Pronuba_) + +This is by far the commonest moth of the genus, and may be found +everywhere, in town and country, from June to August. It is represented +on Plate XI (fig. 1), but its fore wings are very variable, sometimes a +cold dingy grey, but often of an exceedingly rich and warm brown. On the +costal margin, not far from the tip, there is always a small black spot, +which will serve to distinguish it from _Comes_. + +The caterpillar (fig. 21) feeds throughout the winter on the roots of +almost every plant in our gardens; and, during the warmer weather of the +autumn and spring, on stems and leaves. It is full grown early in the +summer, and then changes to a chrysalis in the ground. Its colour is +dirty yellowish or greenish grey, with a row of dark spots on each +side. + + +Family--AMPHIPYRIDÆ + +_The Gothic_ (_Mania typica_) + +The above family contains only four British species, two of which we +shall briefly consider. + +[Illustration: FIG. 161.--THE GOTHIC.] + +The first of these is the Gothic--a very common moth that may be seen +everywhere about midsummer. Its fore wings are brown with darker +marblings, and there are numerous lighter markings which may be easily +made out by reference to the accompanying woodcut. + +The caterpillar is smooth and velvety, of a dull brown or greenish +colour, with darker dorsal and side stripes. The latter are crossed +obliquely by a series of whitish lines. It feeds on fruit and other +trees in clusters when very young in early autumn, and afterwards +descends and feeds on low plants. It hybernates in the winter, and feeds +again on low plants in the spring. When full grown it burrows into the +soil to undergo its changes. + + +_The Old Lady_ (_Mania Maura_) + +This fine moth is so very different from the last in appearance that the +reason for placing the two in the same genus is not apparent till the +earlier stages and life history have been studied. All its wings are +very deep brown; the front pair has a darker band containing the +orbicular and reniform spots, and the hind pair a lighter band across +the middle. + +[Illustration: FIG. 162.--THE OLD LADY.] + +It is a common moth, often to be found at rest by day in outhouses and +sheds. It flies in July and August. + +The caterpillar is dark purple or umber brown, with darker and lighter +markings. It feeds in the autumn on fruit trees, and hybernates during +the winter. In the spring it feeds again on low plants, and changes to a +chrysalis in May under the ground. + + +Family--ORTHOSIIDÆ + +This is a large family of over thirty species, most of them of rather +small size, which make their appearance, with two exceptions, either in +early spring or in late autumn, often attracted in the former season by +the sallow blossom, and in the latter by ivy bloom. + +Several of them are very common insects, that are almost sure to be +taken by a young collector during his first season. + +The fore wings of these moths are more or less pointed at the tip, and +the usual lines and spots are generally distinct. The males may be +distinguished from the females by their antennæ, which are always more +or less ciliated. + +The caterpillars are smooth and velvety, and feed by night; and the pupæ +are inclosed in cocoons constructed of earth and silk. + + +_The Common Quaker_ (_Tæniocampa stabilis_) + +Several of the species of the family are known popularly as Quakers, the +commonest of which--_Stabilis_--is abundant in all parts. + +Its fore wings are grey, with generally either an ochreous or reddish +tinge. The orbicular and reniform spots are outlined with a paler +colour, and there is a pale transverse line parallel with the hind +margin, outside which is a row of indistinct black spots. The hind wings +are greyish brown. + +[Illustration: FIG. 163.--THE COMMON QUAKER.] + +The caterpillar is green and velvety, with a yellowish line on the back +and on each side; and a yellow band crosses the back of the twelfth +segment transversely. It feeds during June and July on oak (_Quercus +Robur_) and elm (_Ulmus campestris_), and changes to a chrysalis in +August on the surface of the ground. In this state it remains throughout +the winter, and the moth emerges in March or April. + + +_The Chestnut_ (_Cerastis Vaccinii_) + +Unfortunately our space will not allow us to notice the whole of even +the very common moths, so, passing over a few with great reluctance, we +come to the familiar Chestnut, which may be seen at large in October and +November, and sometimes even in December, and again appears, after a +rather short period of hybernation, in February and March. + +[Illustration: FIG. 164.--THE CHESTNUT.] + +The fore wings are reddish brown, with darker wavy lines. The orbicular +and reniform spots have pale outlines, and the lower half of the latter +is very dark grey. The hind wings are smoky grey, with generally a pale +band beyond the middle. + +The caterpillar is dark brown, with very indistinct lighter lines. The +spiracles are black, and inclosed in a yellowish grey stripe. It feeds +during June and July on the elm (_Ulmus campestris_), oak (_Quercus +Robur_), and sallow (_Salix caprea_), and various low plants. + + +_The Pink-barred Sallow_ (_Xanthia Flavago_) + +This moth is not nearly so common as the preceding species, but has been +taken more or less in all parts of England. + +Its fore wings are orange yellow, with purplish markings arranged as +represented in fig. 165. The hind wings are yellowish white. + +[Illustration: FIG. 165.--THE PINK-BARRED SALLOW.] + +The caterpillar is brown, with a lateral stripe formed by numerous red, +yellow and white dots. It feeds on sallow (_Salix caprea_) and various +low plants. + +It is full grown in June, and the moth appears in September. + + +Family--COSMIIDÆ + +_The Dun-bar_ (_Calymnia trapezina_) + +Our example of this family is the Dun-bar, common everywhere during July +and August. + +Its fore wings are greyish ochreous, with a darker band across the +middle. On each side of this band is a white line margined with dark +grey, and there is a row of black spots along the hind margin. The hind +wings are smoky brown, becoming paler towards the base. + +[Illustration: FIG. 166.--THE DUN-BAR.] + +The caterpillar feeds on oak (_Quercus Robur_), hornbeam (_Carpinus +Betulus_), and birch (_Betula alba_), and may be found in abundance +during May and June. It is green, with dark spots, and white lines on +the back and sides. Although it partakes of the leaves of the +above-named trees, yet its chief food seems to be other caterpillars, +for it devours these with a savage greediness that is simply +astonishing. It will chase an unfortunate caterpillar, seize it by the +neck with a fatal grip, and rapidly devour it. Its chief prey seems to +be the larva of the Winter Moth (_Brumata_). + + +Family--HADENIDÆ + +Nearly fifty British _Noctuæ_ are included in the family _Hadenidæ_. +They are of variable dimensions, and differ much in the brightness of +their colours, some being very dingy, and others gaily tinted. Their +antennæ are rather long; and when at rest the wings slope from the back +like the sides of a roof. + +The larvæ are smooth, and not very thick; and there is sometimes a hump +on the twelfth segment. The pupæ are brown and shiny, and are inclosed +in earthen cocoons beneath the surface of the soil. + + +_The Broad-barred White_ (_Hecatera serena_) + +Although not gaily coloured, this is a pretty little moth, there being a +bright contrast between the white ground and the grey markings of the +wings. It is common in the south of England, and seems to be plentiful +in and around London. + +[Illustration: FIG. 167.--THE BROAD-BARRED WHITE.] + +The caterpillar is of a dingy greenish colour, with a yellowish stripe +on each side of the back; and there are two distinct dots on the back of +each segment. It feeds during July and August on sow-thistles (_Sonchus +oleraceus_ and _S. arvensis_), sleepwort (_Lactuca virosa_), and +hawkweeds (_Hieracia_). + +The moth flies in June and July. + + +_The Marvel-du-jour_ (_Agriopis Aprilina_) + +The Marvel-du-jour is decidedly a beautiful moth--quite an exception +among the _Noctuæ_ in this respect, and it is withal both common and +widely distributed. We need not describe it, since it is represented on +Plate XI (fig. 2), and can hardly be mistaken for any other species. + +The caterpillar is dull green, often tinged with red. The dorsal line is +broad and dark, and interrupted by a series of very light lozenge-shaped +spots. It feeds on the oak in May and June, and is full grown in the +latter month. It then burrows into the earth at the foot of the tree, +and there constructs a fragile earthen cocoon previous to changing to a +chrysalis. + +From July to September the chrysalides may be obtained in plenty by +breaking up the sods at the roots of oaks, and the perfect insect may be +found toward the end of September and throughout October. + + +_The Small Angle Shades_ (_Euplexia lucipara_) + +This pretty little moth is represented in fig. 3 of Plate XI. It is very +common throughout the country, and may be seen in June and July. + +The caterpillar is thickest on the twelfth segment, and gradually tapers +from this towards the head. Its colour is pale green, with a white +stripe just below the spiracles, which are black. On each side of the +back are a number of oblique lines, which meet in the middle line, thus +forming a series of V-shaped marks pointing towards the tail. It feeds +on the common bracken fern (_Pteris aquilina_), foxglove (_Digitalis +purpurea_), and the male fern (_Lastræa Filix-mas_), in August and +September. + + +_The Angle Shades_ (_Phlogophora Meticulosa_) + +[Illustration: FIG. 168.--THE ANGLE SHADES.] + +This moth is so common and so widely distributed that it is almost sure +to be taken by the young collector during his first season. Its wings +are scalloped on the hind margin, and their colour light ochreous, often +tinged with pink or olive green, and marked with dark brown as shown in +the illustration. It is double brooded, the first brood appearing in May +and June, and the second in September and October. + +The caterpillar is green or olive brown, and thickly covered with white +spots. It feeds on groundsel (_Senecio vulgaris_) and many other low +plants, the first brood throughout the winter from November to April, +and the second in July and August. + + +_The Grey Arches_ (_Aplecta nebulosa_) + +The fore wings of this moth vary from greyish white to a rather dark +smoky tint. The markings are of a darker colour, and are also subject to +considerable variation. The orbicular and reniform spots are large, and +paler than the ground colour; and several zigzag or scalloped lines, +more or less distinct, cross the wings transversely. + +[Illustration: FIG. 169.--THE GREY ARCHES.] + +The larva is brown, with a lighter line down the back. On each of the +segments five to eleven is a dark lozenge-shaped spot, bisected by the +dorsal line; and on the second segment is a shining plate and a +triangular mark. It feeds on the dock (_Rumex_), and various other low +plants during the autumn; and, after its hybernation, on the leaves of +the sallow (_Salix Caprea_), birch (_Betula alba_), and whitethorn +(_Cratægus oxyacantha_). It is full grown in May, when it burrows into +the ground to undergo its metamorphoses. + +The moth flies during June and July, and is common in nearly every part +of Great Britain. Large numbers may be obtained by searching fences and +tree trunks about midsummer. + + +_The Shears_ (_Hadena dentina_) + +The Shears is another very common moth of the same family. The ground +colour of the fore wings is very variable, but is generally a lighter or +darker shade of grey. Sometimes, however, it has a very decided brownish +tinge. Across the centre of the wing is a darker band, wider on the +costal side, containing the orbicular and reniform spots, as well as a +light patch beneath them, and bordered on each side by a pale zigzag +line. There is another similar line near to and parallel with the hind +margin. The hind wings are smoky grey or smoky brown, darker towards the +hind margin. + +[Illustration: FIG. 170.--THE SHEARS.] + +The caterpillar is greyish, and has a series of triangular black spots +along each side of the back. It feeds on the roots of the dandelion +(_Taraxacum officinale_), and changes to a peculiar spiny chrysalis. + +The perfect insect appears to be abundant everywhere, and is on the wing +in June and July. + + +_The Bright-line Brown-eye_ (_Hadena oleracea_) + +Every collector is sure to meet with this insect during his first +season. The moth is abundant everywhere in June, the caterpillar may be +found feeding in almost every waste and weedy spot in August and +September, and the chrysalis is certain to be turned over by the pupa +digger. + +[Illustration: FIG. 171.--THE BRIGHT-LINE BROWN-EYE.] + +The fore wings of the perfect insect are reddish brown. The orbicular +spot is usually very indistinct, being of almost exactly the same tint +as the ground colour, and surrounded by a very fine whitish line. The +reniform is generally more conspicuous, a portion of it being of a light +ochreous colour. Near the hind margin, and parallel with it, is a white +line, bent sharply into the form of a W, just on the anal side of the +middle. + +The hind wings are greyish brown in the base, and dark smoke colour +towards the margin. + +The caterpillar is pale green or brown, dotted with both black and +white, and adorned with a bright yellow line just below the spiracles. +It feeds on the nettle (_Urtica dioica_), dock (_Rumex_), and many other +low plants; and, according to some observers, on the elm (_Ulmus +campestris_). + + +Family--XYLINIDÆ + +The next family--_Xylinidæ_--contains twenty British species, several of +which are local, but two or three are abundant and widely distributed. + +The transverse lines that so often cross the wings of the _Noctuæ_ are +nearly or entirely absent in this family, and longitudinal lines take +their place. When the insects are at rest the wings are folded rather +closely, the outer pair being arranged like a roof with a very gentle +slope. The bodies of the perfect insects are very stout, particularly in +the thorax, and thus present a rather powerful appearance. + +The larvæ are smooth, and generally brightly coloured, and feed +principally on low plants. The chrysalides are generally inclosed in +cocoons on or beneath the ground, and are often provided with spines or +bristles on the under side. + +We shall select two members of this family. + + +_The Early Grey_ (_Xylocampa Areola_) + +One of the first of the _Noctuæ_ to greet us in the spring is the Early +Grey, which may be found resting on fences in April, and, if the season +is mild, in March. + +[Illustration: FIG. 172.--THE EARLY GREY.] + +Its fore wings are light grey, often tinged with rose pink, and marked +with dark grey. The orbicular and reniform spots are very distinct, and +surrounded by a pale line; they are both united at their lower edges. +Along the hind margin is a series of dark spots. The hind wings are pale +yellowish grey, with a darker central spot, a central transverse darker +line, and a darker line along the hind margin. + +The caterpillar is yellowish grey. The dorsal line is lighter, and +passes through a brownish spot on the eighth segment. It feeds on the +honeysuckle (_Lonicera Periclymenum_) in July and August, being full +grown towards the end of the latter month. + + +_The Shark_ (_Cucullia umbratica_) + +The Shark is a very common moth, to be found everywhere on palings in +June, but the colour of its wings so closely resembles that of oak and +other light-wood fences that detection is not so easy as with most other +moths. + +[Illustration: FIG. 173.--THE SHARK.] + +The fore wings are grey, and marked with longitudinal dark lines, the +principal of which is a line from the middle of the base to about the +centre of the wing. The wing rays are also darker than the ground +colour. The hind wings are greyish white or brownish grey. + +The caterpillar is very dark brown, with orange spots on the back and +along the spiracles. It feeds on sow-thistles (_Sonchus oleraceus_, _S. +palustris_, and _S. arvensis_) and sleepwort (_Lactuca virosa_) at night +from July to September, and hides during the daytime among the leaves +that lie close against the ground. When disturbed it does not roll into +a ring or feign death like many others of its kind, but wriggles about +most vigorously as if to repel its foe. + + +Family--GONOPTERIDÆ + +_The Herald Moth_ (_Gonoptera Libatrix_) + +The above-mentioned family is so called on account of the angular +margins of the wings, especially the fore pair. It contains only one +British species, the Herald (Plate XII, fig. 1), a moth that is common +everywhere in August and September. It hybernates in the perfect state, +and the hybernated specimens may be seen in the spring time, from March +up to the end of May or the beginning of June. + +Its fore wings are reddish grey, thickly spotted and streaked with +brown. Transverse whitish lines divide the base into three parts of +nearly equal widths. The basal and central divisions are tinged with +orange; and there is a small white spot in the base close to the thorax, +also another near the centre of the wing. The hind wings are brownish +grey. + +The caterpillar is green and velvety, with a whitish stripe on the side, +and yellow spiracles. It feeds on willow (_Salix alba_) and sallow +(_Salix caprea_); and when full grown, about the end of June, it spins a +white silken cocoon between leaves of its tree, and changes to a very +dark chrysalis. + + +Family--PLUSIIDÆ + +The most peculiar feature of the moths of this family is the tufts of +hair that stand up perpendicularly on the top of the thorax. The abdomen +also is crested, and the fore wings of several species have smooth +patches that display a brilliant metallic lustre. + +Most of the larvæ may be described as semi-loopers, for their claspers +number only three pairs, and when they walk their backs are considerably +humped, somewhat after the fashion of the _Geometræ_. Some of them +further imitate the _Geometræ_ in their position of rest, holding on by +their claspers only, with body straightened out at an angle with the +leaf or twig on which they support themselves. + +Unlike the majority of the _Noctuæ_, they do not descend to the ground +when about to change, but spin a silken cocoon among the food plants. + + +_The Burnished Brass_ (_Plusia Chrysitis_) + +One of the commonest of the _Plusiidæ_ is the Burnished Brass, so called +on account of the large patches of bright golden green on the fore +wings. The hind margin of these wings is very gracefully curved, and +bordered with brown. A brown blotch fills the base of the wing, and the +remaining area is of a beautiful metallic greenish yellow, broken by two +large brown blotches, one on the costal and the other on the inner +margin, which closely approach each other and sometimes meet. + +[Illustration: FIG. 174.--THE BURNISHED BRASS.] + +This moth is very common everywhere, and is one of the frequent visitors +to our flower gardens from June to August. + +The caterpillar is thickest at the twelfth segment, and tapers from this +point. Its colour is pale green. It has no longitudinal stripes on the +back, but each segment is adorned with four or six oblique white marks. +Just above the spiracles is a white stripe. It feeds on the dead nettle +(_Lamium album_), stinging nettle (_Urtica dioica_), and burdock +(_Arctium minus_), and is full grown in June. + + +_The Silver_ Y (_Plusia Gamma_) + +Our second example of this family is the Silver Y, which may be found in +abundance everywhere from June to October. Its fore wings are of a shiny +grey colour, beautifully marbled with a rich dark brown; and just below +the orbicular spot is a brilliant silvery spot, in form something like +the Greek letter [gamma] placed obliquely. The base of the hind wings is +grey; along the margin is a broad and dark smoky brown band, and the +fringe is very light grey, barred with the dark tint of the band. This +moth is commonly driven out of its hiding places among low plants as we +walk in waste places, and when thus disturbed it takes a short and rapid +flight, generally disappearing so suddenly among the herbage that it is +difficult to locate it correctly. + +[Illustration: FIG. 175.--THE SILVER Y.] + +The caterpillar is thickest at the twelfth segment, and tapers gradually +from this point towards the head. Its body is green, with several thin +longitudinal white stripes, and a thin yellow stripe along the +spiracles. It may be found from June to October, feeding on many kinds +of low plants. + + +Family--EUCLIDIIDÆ + +_The Mother Shipton_ (_Euclidia Mi_) + +Passing over a few small and less important families, we come to the +_Euclidiidæ_, which contains only two British moths. One of these is the +Mother Shipton, a very common insect that flies in June. + +The fore wings of this species are very dark brown with whitish +markings. The latter include a peculiarly tortuous line, the character +of which will be made out more easily from our illustration (Plate XI, +fig. 4) than from a written description. The hind wings are also very +dark brown, and rather prettily spotted with an ochreous tint. + +The caterpillar is pale grey, with four white stripes, and has only +three pairs of claspers. It feeds in May on clovers (_Trifolium +pratense_ and _T. repens_) and other plants. + + +Family--CATOCALIDÆ + +This family contains only four British species, but these few are very +striking moths. They are of large size; and, unlike the _Noctuæ_ +generally, the chief adornment is reserved for the under wings. When at +rest, the outer or fore wings completely hide the other pair, and then +their general appearance is dull, though if closely examined it will be +observed that these outer wings are really beautifully marbled with +shades of grey. + +The caterpillars of this family are very peculiar creatures. Their +bodies are convex above and flattened beneath; and if disturbed as they +rest on the bark of a tree, instead of leaving their hold and rolling +into a ring like so many other larvæ of _Noctuæ_, they apply themselves +the closer, and hold on as if to defy our attempts to remove them. +Another peculiarity of these larvæ is the possession of fleshy +projections along the sides, just above the legs. They feed on the +leaves of trees, and when about to rest they descend to the trunk, and +there remain protected by their imitative colouring, detection being +rendered even more difficult by the close application of their flattened +under surface to the bark. Before changing to the chrysalis state, they +spin a light cocoon among the leaves or on the bark. + + +_The Clifden Nonpareil_ (_Catocala Fraxini_) + +This is the largest of the family, and, indeed, of all British _Noctuæ_. +The fore wings and thorax are light grey, dotted and marbled with darker +grey (see fig. 5, Plate XI); and the thorax and abdomen are banded with +black and greyish blue. + +The young entomologist can hardly expect to meet with this fine insect, +for it is very rare, and it is only occasionally that a specimen is seen +in Britain; but its characteristics are so striking that we have +endeavoured to find it a place here. Reputed British specimens of +_Fraxini_ command the price of a few pounds each, but specimens from the +other side of the Channel may be obtained for a few pence. With such +rarities we should advise a young entomologist to purchase the foreign +specimen rather than adopt the two other alternatives--give an +exorbitant price for a supposed Britisher, or else remain a stranger to +the gem, but all foreign specimens should be labelled according to their +nationalities. + + +_The Red Underwing_ (_Catocala Nupta_) + +The other three members of the family are very similar in appearance, +the fore wings of all being marbled with shades of grey, relieved by +touches of black and brown; and the hind wings, red or crimson, give the +popular names to the species. + +The Red Underwing flies in August and September, and is common in the +southern counties of England, as well as in some of the midland +counties; it may be often seen flying by day around willows. + +[Illustration: FIG. 176.--THE RED UNDERWING.] + +The caterpillar is similar in form to that of _Fraxini_, and when at +rest by day on the bark of its tree it is very difficult to detect, so +closely does it apply itself to the surface, and so perfectly does it +imitate the colour of its surroundings. It feeds on the crack willow +(_Salix fragilis_), sallow (_S. alba_), poplar (_Populus_), and plum +(_Prunus_), and is full grown in June. + + +_The Dark Crimson Underwing_ (_Catocala Sponsa_) + +This beautiful insect is represented on Plate XI (fig. 6). It will be +observed that the black band crossing the centre of the hind wing is +rather broad and sharply bent--an important feature, since it is the +most serviceable distinguishing mark between this species and the Light +Crimson Underwing (_C. Promissa_). + +The caterpillar is similar in form and habits to those of _Fraxini_ and +_Nupta_, and feeds on the oak. It is full fed about the beginning of +June, when it changes to a chrysalis between leaves which it has spun +together with silk. + +The moth flies in July and August, and is common only in certain oak +woods of the southern counties. It is particularly abundant in the New +Forest, where scores may be taken in a single night by judicious +sugaring. + +There yet remain a few small families of the _Noctuæ_, but we must leave +them in order that we may give a proportionate share of our space to the +other great division of the larger moths--the _Geometræ_. + + + + +CHAPTER XX + +_GEOMETRÆ_ + + +We have already referred (page 28) to caterpillars that walk by a +series of strides, alternately looping and extending their long and +slender bodies. It is this peculiar characteristic of the larvæ of +the present division that suggested the name _Geometræ_--a term that +signifies 'earth-measurers,' for they appear to measure the ground +over which they travel in terms of their own length. We have also +dealt with the peculiarities of structure in the case of these +caterpillars--peculiarities which adapt them to this mode of +progression; and we have now to make a selection from the various +families of this important division for a more detailed description. + +The _Geometræ_ include nearly three hundred species and sixteen +families. The moths have slender bodies and full wings, and generally +rest with the latter outspread. A few, however, repose with wings erect +like the butterflies, and a small number conceal their hind wings after +the manner of the _Noctuæ_. + + +Family--UROPTERYGIDÆ + +_The Swallow Tail_ (_Uropteryx sambucaria_) + +Our first family--_Uropterygidæ_--has only one British representative, +and that is the well-known Swallow Tail, so common in gardens and among +hedgerows in the south of England. This species is shown on Plate XII +(fig. 2), and the insect is so readily identified by the conspicuous +'tails' on the hind wings that no written description will be necessary. + +The caterpillar is a most peculiar and interesting creature. Its colour +is very variable, being either brown, olive, ochreous, or reddish; and +it is notched or humped in such a manner that it exactly resembles a +twig. This strange imitation is rendered still more remarkable by the +attitude assumed by the caterpillar when at rest. It fixes itself to a +twig by means of its two pairs of claspers, with its body standing out +at an angle in a perfectly straight posture; but its head is always +supported by means of a very slender and almost invisible silk fibre. It +feeds on a number of plants and trees, including elder (_Sambucus +nigra_), blackthorn (_Prunus spinosa_), whitethorn (_Cratægus +oxyacantha_), bramble (_Rubus fruticosus_), honeysuckle (_Lonicera +Periclymenum_), and forget-me-not (_Myosotis arvensis_). It may be found +feeding in the autumn, or hybernating in the crevices of the bark of +trees in winter. In April or May it comes out again; and in June, in +which month it is full grown, it binds together some fragments of +leaves, and forms them into a little swinging hammock in which it +changes to a brown chrysalis spotted with black. + +Just at this time it seems to be particularly sensitive. In the +caterpillar state it will strongly resent any kind of disturbance, and +will give a blow to an intruder by suddenly swaying its body right and +left; and while in its hammock a gentle irritation, such as a puff of +wind from the mouth, will set it wriggling in a furious manner. + + +Family--ENNOMIDÆ + +This family contains about twenty species, several of which rank among +the commonest as well as the most beautiful of the _Geometræ_. Their +wings are more or less angulated; and the antennæ are generally +pectinated in the males. + +The larvæ are generally humped and twig-like; and, as in the last +species, the semblance is increased by the position they assume when at +rest. The number of limbs varies from ten to fourteen, but where the +claspers exceed two pairs, the additional two or four, as the case may +be, are seldom used in walking. + + +_The Brimstone Moth_ (_Rumia luteolata_) + +As soon as the warm evenings of May set in, this lively and bright +little moth may be seen flitting about among our hedges at sunset; and +it continues with us throughout the whole of the summer, but is +particularly plentiful during the month of June. + +The moth itself need not be described, since it is shown on Plate XII +(fig. 3); but the caterpillar (fig. 25) must receive a passing notice. +It varies considerably in colour, being either green, brown, or marbled +with a mixture of shades of both these colours. It has a hump on the +back of the seventh segment, and two more on the ninth, and possesses +four pairs of claspers. It feeds on whitethorn (_Cratægus oxyacantha_), +blackthorn (_Prunus spinosa_), and the apple (_Pyrus Malus_), and may be +found on these trees throughout the summer. + +Some believe that there are three successive broods of this insect each +year, but it is doubtful whether this is invariably the rule, since both +the moth and its larva are to be found without intermission throughout +the season. + + +_The Light Emerald_ (_Metrocampa margaritaria_) + +All the wings of this moth are very pale green, and crossed with a white +band which is bordered with a darker green on the inner side. The fore +wings have an additional transverse line just halfway between the former +and the base, but this one is not so distinct. It flies in July, and is +very widely distributed, and in some parts is very abundant. + +[Illustration: FIG. 177.--THE LIGHT EMERALD.] + +The caterpillar feeds in September, and again in May, after hybernation, +on several of our forest trees, including the oak (_Quercus Robur_), elm +(_Ulmus campestris_), birch (_Betula alba_), and beech (_Fagus +sylvatica_). It is of a dingy olive colour, with a dark dorsal line, on +each side of which is a row of white spots; and it has three pairs of +claspers. + + +_The Scalloped Oak_ (_Crocallis elinguaria_) + +This species is common and widely distributed, and may be seen flying at +dusk towards the end of July and throughout August. It is represented in +fig. 4 of Plate XII. The antennæ of the male are strongly pectinated; +those of the female are simple. + +The caterpillar may be found in the autumn, and again in spring, feeding +on the honeysuckle (_Lonicera Periclymenum_), whitethorn (_Cratægus +oxyacantha_), blackthorn (_Prunus spinosa_), beech (_Fagus sylvatica_), +and various fruit trees. It is full grown in June, when it turns to a +chrysalis in a cocoon spun between leaves or moss on or near the ground. +It is of a greyish-brown or greyish-purple colour, and looks very like a +piece of twig. + + +_The August Thorn_ (_Eugonia quercinaria_) + +Our last example of this family is the August Thorn, represented in the +accompanying woodcut. The fore wings are ochreous yellow, crossed by two +nearly parallel lines of dark brown. In order to distinguish between +this and one or two similar species it must be observed that both these +lines are angulated near the costa, the inner one very sharply so; and +between the two is a distinct brown spot near the costal margin. The +hind wings are paler, and are crossed by an indistinct darker line. The +antennæ of the male are strongly fringed; those of the female are +simple. + +[Illustration: FIG. 178.--THE AUGUST THORN.] + +The moth is very common in August and September, and is readily +attracted by lights in the evening. + +The larva is grey, marbled with reddish brown. It has three small humps +on each of the sixth and seventh segments, two on the twelfth, and one +larger one on the ninth. It feeds on the oak and various other trees +during the month of June. + + +Family--AMPHIDASYDÆ + +The seven British species of the family _Amphidasydæ_ are generally to +be distinguished by their rather stout abdomens, and the long shaggy +hair that covers their thoraces. The antennæ of the males are +pectinated, and those of the females simple; and in three cases the +latter sex is wingless. + +The caterpillars have long and slender twig-like bodies, and are never +provided with more than two pairs of claspers. The chrysalides terminate +behind in a sharp spine, and are always to be found buried in the soil. + + +_The Brindled Beauty_ (_Biston hirtaria_) + +Early in April, and sometimes in March, this moth may be seen in +abundance, resting on the lime trees in and around our towns. In fact, +so strongly marked is its partiality to the haunts of man in the +neighbourhood of our great metropolis that it has received the name of +the Cockney. The male is represented in fig. 5 of Plate XII, and the +female may be distinguished from it by her simple antennæ and larger +body. + +The caterpillar is coloured with alternate bands of dark purple brown +and reddish brown. There is a yellow band on the front of the second +segment, a row of yellow spots on each side, and two little bright +yellow warts on the back of each segment. It feeds by night on lime +(_Tilia vulgaris_), elm (_Ulmus campestris_), and various fruit trees, +and often appears in such numbers that the foliage is almost completely +devoured. During the daytime it may be seen resting on the bark, almost +invariably fixed longitudinally on the trunk, where it looks like a +natural ridge of the bark which it so closely resembles in colour. It +may be found in June and July, and in August it changes to a chrysalis +at the foot of its tree, just below the surface of the soil. + + +_The Peppered Moth_ (_Amphidasys betularia_) + +Although this common species displays no bright tints, yet it is +prettily marked, its whitish wings being peppered and blotched all over +with black or very dark brown. It flies in May and June, later than any +other species of the family, and may generally be found on fences and +tree trunks during the day. + +[Illustration: FIG. 179.--THE PEPPERED MOTH.] + +The colour of the caterpillar is very variable--drab, grey, green, or +brown; but it may be known by the deep notch in the middle of the head, +and the arrangement of its 'humps.' These latter are only small reddish +or whitish projections, of which there is one on each side of the fifth, +sixth, seventh, eighth, tenth, and eleventh segments; also two on the +back of the ninth and twelfth. It feeds in August and September on a +large number of trees, including, in fact, nearly all our commonest +forest and fruit trees. In September it enters the soil to undergo its +change to the chrysalis. + + +Family--BOARMIIDÆ + +In the next family--_Boarmiidæ_--there are about twenty British members, +most of which are very pretty moths. They differ generally from the last +family in that their bodies are more slender, and although some of them +bear a resemblance to species of the family _Ennomidæ_, their wings are +not angulated. In several cases the fore and hind wings are both +similarly marked, a feature very uncommon with moths. + +The caterpillars of this family usually have humps on the sixth and +twelfth segments only, and have two pairs of claspers. The pupæ are to +be found either on the ground, among leaves or moss, or beneath the +soil. + + +_The Waved Umber_ (_Hemerophila abruptaria_) + +The most gaily coloured member of this family is the Waved Umber, shown +in fig. 6 of Plate XII. Like many other _Geometræ_, it rests on fences +and tree trunks by day with wings expanded so that all four are +displayed. It is on the wing in May and early June, and again in August, +and often frequents our gardens at dusk. + +The caterpillar is very dark brown, with a white collar on the front of +the second segment. It feeds in June and July on privet (_Ligustrum +vulgare_) and the cultivated rose trees of flower gardens, and probably +also on the dog rose (_Rosa canina_). When full grown it spins a silken +cocoon in a fork of one of the twigs, and there undergoes its +metamorphoses. + + +_The Willow Beauty_ (_Boarmia gemmaria_) + +Our second example of the _Boarmiidæ_ is the Willow Beauty, the male of +which species is here illustrated. Its wings are brownish grey, marked +with dark brown lines and streaks. The female is generally larger than +the male, and has simple antennæ. The moth is abundant throughout +England, and may be seen generally resting on fences and trees in June +and July. + +[Illustration: FIG. 180.--THE WILLOW BEAUTY.] + +The ground colour of the caterpillar is much the same as that of the +moth, and is marked with a similar darker tint. It has a yellowish line +along the spiracles, and is much like a piece of brownish twig. It feeds +on the oak (_Quercus Robur_), Birch (_Betula alba_), ivy (_Hedera +Helix_), and other trees, and may be found in September and October. + + +Family--GEOMETRIDÆ + +The next family contains eight moths, mostly of small size, all of which +have green wings, and are popularly known as the 'Emeralds.' In most +cases the male may be distinguished by its pectinated antennæ. + +There is no general characteristic by which we may know all the larvæ, +but some have the head deeply notched. + + +_The Large Emerald_ (_Geometra papilionaria_) + +This species is the largest of the family, and measures over two inches +when its wings are expanded. The colour is dull green, with whitish +bands and spots, the arrangement of which may be seen in our engraving. + +[Illustration: FIG. 181.--THE LARGE EMERALD.] + +The moth is out in July, and is common in most parts of England. + +The caterpillar feeds on birch (_Betula alba_), beech (_Fagus +sylvatica_) and hazel (_Corylus avellana_) in the autumn, and hybernates +while still young. In the spring it feeds again, and is full grown in +June, when it changes to a chrysalis in a cocoon spun between leaves. + + +_The Common Emerald_ (_Hemithea strigata_) + +One of the commonest of the Emeralds is _Strigata_, which may be found +in June and July in all parts of England, as well as in some localities +in Scotland and Ireland. Its wings are of a dull green colour, the front +pair being slightly scalloped on the hind margin, and crossed by +indistinct pale lines; and the hind pair are both scalloped and angled +and crossed in the middle by a transverse pale line. The fringe is +white, dotted with dull reddish brown. + +[Illustration: FIG. 182.--THE COMMON EMERALD.] + +The caterpillar is yellowish green, except the second, third, and fourth +segments which are brownish. It feeds on oak (_Quercus Robur_) and +whitethorn (_Cratægus oxyacantha_), and may be found in June. + + +Family--EPHYRIDÆ + +_The Maiden's Blush_ (_Zonosoma punctaria_) + +The family _Ephyridæ_ contains only six British species, chiefly +remarkable for the fact that their pupæ generally resemble those of +butterflies. + +We choose for our example the pretty little Maiden's Blush, so called on +account of the soft reddish patch on the middle of each fore wing. It is +represented in fig. 7 of Plate XII. It is moderately common, occurring +more or less in all parts of England, as well as certain localities in +the sister countries. It is a double-brooded moth, and may be caught in +May and August. + +The caterpillar feeds on oak (_Quercus Robur_), from which it may be +obtained by beating both in June and September. It is either green or +tawny yellow, marked with yellow oblique lines on the sides. + + +Family--ACIDALIIDÆ + +The moths of this family, over thirty in number, are mostly of small +size, and have slender bodies. As a rule the wings are not in the least +angulated or scalloped, but in a few species the hind pair are slightly +angled on the hind margin; and both fore and hind wings are similarly +marked. The antennæ are simple in the females, and generally only +slightly ciliated in the males. + +The caterpillars are long and slender, without projections, and feed +principally on low plants. The pupæ are to be found in loose cocoons +among the leaves of the food plants or under the soil. + +We shall briefly notice three members of this rather extensive family. + + +_The Lace Border_ (_Acidalia ornata_) + +The wings of this moth are silvery white, marked along the hind margin +with a beautiful lace-like border. This border consists of delicate +black and dark grey lines, and includes, in the fore wing, two light +brown blotches, one near the middle and the other in the anal angle. It +is abundant in England, particularly in chalky districts, but does not +seem to extend into Scotland. It may be seen on the wing from June to +August. + +[Illustration: FIG. 183.--THE LACE BORDER.] + +The caterpillar feeds on thyme (_Thymus Serpyllum_) and marjoram +(_Origanum vulgare_). + + +_The Riband Wave_ (_A. aversata_) + +All the wings of this species are of a pale yellowish or ochreous grey. +The fore wings are crossed by three transverse dark lines, and the hind +wings by two. The space between the two outer lines of the fore wing and +that between the lines of the hind wing are usually filled in with a +greyish brown, thus forming the 'riband' from which the popular name of +the insect is derived; and when this is the case the lines which border +the riband are scarcely distinguishable. Just inside the second line of +the fore wings, near the costa, is a small but conspicuous brown spot. + +[Illustration: FIG. 184.--THE RIBAND WAVE.] + +The moth flies in June and July, and is common in all parts. + +The caterpillar is dark brown except segments ten to thirteen, which are +grey. The line along the spiracles is whitish, and the surface of the +body is roughened by a number of minute warts. It feeds on various low +plants, including the meadow sweet (_Spiræa ulmaria_), water avens +(_Geum rivale_), common avens (_G. urbanum_), and knot-grass (_Polygonum +aviculare_), during April and May. + + +_The Blood-vein_ (_Timandra amataria_) + +Our last example of the _Acidaliidæ_ is the Blood-vein, which is common +in most parts of England in June and July. + +[Illustration: FIG. 185.--THE BLOOD-VEIN.] + +Its fore wings are pale grey, dusted with darker grey, and crossed by an +oblique red streak which runs from the tip of the fore wing to near the +inner margin of the hind wing. A slender dark and wavy line lies outside +this one, parallel with it in the hind wing, but meeting it near the tip +of the fore wing. + +The caterpillar is grey, with three white longitudinal stripes. It feeds +in the autumn on dock (_Rumex_), sorrel (_R. acetosa_), and knot-grass +(_Polygonum aviculare_). + + +Family--CABERIDÆ + +Six species, all of rather small size, constitute the British portion of +the above family. Their wings are mostly white or pale grey, with light +markings, and without angles. The moths are to be caught with the net +at dusk, or they may be seen on fences and tree trunks during the day, +with their wings fully extended and applied closely to the surface on +which they rest. + +The larvæ, which have no humps, feed on trees, and change to the +chrysalis state in light silken cocoons. + + +_The Common Wave_ (_Cabera exanthemata_) + +The first of our two examples of this small family is the Common Wave, +the wings of which are pale grey, almost white, dusted all over with +small dark dots. The fore wings are crossed by three parallel and +equidistant darker transverse lines, and the hind pair by two. The male +may be distinguished by its ciliated antennæ. + +[Illustration: FIG. 186.--THE COMMON WAVE.] + +The caterpillar is yellow or greenish yellow, with hinder segments +slightly swollen. It feeds during the latter part of the summer on +sallows (_Salix caprea_ and _S. cinerea_) and alder (_Alnus glutinosa_), +and changes to a chrysalis in a light cocoon among fallen leaves. In +this state it spends the winter, the perfect insect emerging in May or +June. + +This species is very abundant in most parts. + + +_The Clouded Silver_ (_Bapta temerata_) + +The other example is the Clouded Silver, the wings of which are white, +and clouded along the hind margin with smoky grey. On the hind margin of +the fore wings, close to the fringe, is a row of black crescent-shaped +spots; and on the inner side of the cloudings is a waved transverse +band. In the centre of the same wings there is a very distinct dark +spot. + +[Illustration: FIG. 187.--THE CLOUDED SILVER.] + +This moth is not so common as the last, but is widely distributed. It +flies in May and June. + +The caterpillar is bright green on the upper side, and has a row of +orange spots, bordered with brown, down the middle of the back. It feeds +in the autumn on the blackthorn (_Prunus spinosa_) and the wild cherry +(_P. Avium_), and spends the winter in the chrysalis state, inclosed in +a light silken cocoon. + + +Family--MACARIIDÆ + +_The_ V _Moth_ (_Halia Vauaria_) + +The family _Macariidæ_ contains only five British species, four of which +have the tip of the fore wings extended more or less into an angle, and +the hind wings are also angled to a greater or less extent. + +[Illustration: FIG. 188.--THE V MOTH.] + +Our only example is the V Moth, so called from the conspicuous V-shaped +blackish mark on the middle of the costa of the fore wings. The ground +colour of all the wings is grey, with a delicate violet tinge. There are +other dark markings in addition to the one mentioned above, and the +arrangement of these may be seen in the woodcut. + +This species is very common in all parts, and flies at about midsummer. + +The caterpillar is very variable in colour, but is generally green, and +is marked with longitudinal wavy lines. On each side is a series of +yellow blotches, forming a broken lateral stripe, and the body is +covered with minute black bristle-bearing warts. It feeds in May on +gooseberry and currant bushes, and changes to a chrysalis in a web +between the leaves. + + +Family--FIDONIIDÆ + +We now come to a family of moths peculiar for their habit of flying more +or less by day. As is often the case with day-flying moths, these are +mostly prettily marked, and are consequently often mistaken by the +uninitiated for butterflies. Most of them are to be found on heaths, +downs, and open fields; but one--the Bordered White--is met with only in +fir woods. + +The wings are not angulated, and the antennæ of the males are +pectinated. + +The larvæ are generally to be distinguished by a couple of little horns +on one or more of the hindermost segments, and in most cases they pupate +beneath the surface of the soil. + + +_The Common Heath_ (_Ematurga atomaria_) + +Of this family we shall select two examples, the first of which is the +Common Heath, often so abundant on heaths and downs that they are +disturbed at almost every footstep. + +The ground colour of the wings of the male is a dull yellowish grey, and +that of the female greyish white. In both cases the wings are crossed by +irregular dark brown bands. The fringe is barred alternately with white +and dark brown, and the whole of the ground tint between the +above-mentioned bands is thickly dotted with dark brown. The female is +generally smaller than the male. + +[Illustration: FIG. 189.--THE COMMON HEATH.] + +The caterpillar is very variable in colour, but is generally reddish +brown, ochreous brown, or greenish, with a light line along the +spiracles, and a series of lozenge-shaped spots on the back. It feeds on +trefoils (_Lotus corniculatus_ and _L. pilosus_) and various other +plants that grow on heaths. + + +_The Bordered White_ (_Bupalus piniaria_) + +The male of this species is boldly marked with yellowish white and dark +brown, the arrangement of the two colours being shown in fig. 190. The +female is very different in general appearance. Her wings are of an +almost uniform orange or yellowish-brown tint. The fore wings are darker +near the tip, and there is generally a darker transverse band across the +centre. + +[Illustration: FIG. 190.--THE BORDERED WHITE--MALE.] + +The male may often be seen flying in the sunshine among the branches of +fir trees during May and June, but his mate is rather less active, and +is generally to be secured by beating the branches. + +The caterpillar is pale green, with whitish stripes and yellow +spiracles. It feeds during August and September on the leaves of the +Scotch fir (_Pinus sylvestris_). + + +Family--ZERENIDÆ + +_The Currant Moth_ (_Abraxas grossulariata_) + +The family _Zerenidæ_ contains only four British moths, and of these we +select the Currant Moth or Magpie. This insect is exceedingly common +everywhere, and on account of its general brightness of appearance, and +also of its diurnal habits, it is often taken for a butterfly. The +ground colour of the wings is creamy white, with a yellow transverse +band, and a yellow blotch at the base; and the whole surface is more or +less blotched with black. + +[Illustration: FIG. 191.--THE CURRANT MOTH.] + +From the end of June to August this moth may be seen in abundance in our +gardens, wherever currant bushes exist, flying about both during the +sunshine and at dusk, with rather a heavy movement. + +The caterpillar is white, with a yellow line along the spiracles, and +numerous black dots. There are, in addition to the dots, two large black +blotches on the back of each segment. It feeds during May on currant and +gooseberry bushes, also on the blackthorn (_Prunus spinosa_). About the +end of May it spins a light silken cocoon, and changes to a short dumpy +chrysalis of a glossy black colour with bright yellow bands (fig. 34). + + +Family--HYBERNIIDÆ + +Passing over the family _Ligiidæ_, which contains only one British moth, +the Horse-chestnut, we come to the small but interesting family, +_Hyberniidæ_. + +Of this we have six species, five of which favour us during the bleakest +months of the year. Two of them visit us in October and November, and +even remain with us up to Christmas. The others follow closely on them, +and may be seen from January to March. + +The males have slender bodies, and their wings are full and without +angles; but the females are either perfectly or nearly wingless. In +three cases there is hardly a trace of wings in this sex, so that they +look more like spiders than moths. + +The caterpillars are long and slender and without humps, and all feed on +the leaves of trees. They change to the chrysalis state under the +ground. + + +_The Spring Usher_ (_Hybernia leucophæaria_) + +Early in February, and often even in January, this moth may be seen in +abundance in almost every oak wood, sitting on the bark of the trees, +or occasionally taking a short flight in the sunshine. In colour it is +very variable. The wings have always a whitish ground marbled and dotted +with dark brown, but in some the fore wings are almost entirely dark +brown with the exception of a transverse central bar. The female has +only the slightest rudiments of wings. + +[Illustration: FIG. 192.--THE SPRING USHER.] + +The caterpillar feeds on the young buds and leaves of the oak (_Quercus +Robur_) and sycamore (_Acer Pseudoplatanus_), concealing itself among +the small leaves which it has spun together. It is full grown in June, +when it changes to a chrysalis on the surface of the ground, and remains +here throughout the summer and part of the following winter. + +The colour of the caterpillar is very variable, but is usually pale +green with white markings. + + +_The Mottled Umber_ (_Hybernia defoliaria_) + +This very pretty moth is represented in fig. 8 of Plate XII. It is very +common in most parts, and visits us at the fall of the leaf, generally +appearing in October, and remaining on the wing till November. Our +illustration gives the usual appearance of the male, but in some +specimens the four wings are all of one uniform reddish-brown colour, +evenly dotted all over with a darker tint. The female is quite wingless. + +The caterpillar is exceedingly pretty. Its head is large and brown. The +back is brown, bordered with a fine black line. Below this is a broad +and bright yellow line, with a red spot on each segment. The spiracles +are white. It feeds during spring on oak (_Quercus Robur_), whitethorn +(_Cratægus oxyacantha_), blackthorn (_Prunus spinosa_), and other trees. +When disturbed it always allows itself to fall for a foot or two, and +then remains swinging at the end of a silken fibre till danger is over, +or hunger recalls it to its food. It changes to a chrysalis on the +ground about the middle of June. + + +_The March Moth_ (_Anisopteryx æscularia_) + +This is another common moth, and should be looked for during March and +April on the barks of trees in oak and other woods. The fore wings are +of a dingy brown colour, paler near the base, and crossed by a pale wavy +line. The hind wings are lighter, with a central dark spot. But this +description applies to the male only, for the female is wingless, and +may be known by the tuft of hair that tips the abdomen. + +[Illustration: FIG. 193.--THE MARCH MOTH.] + +The caterpillar is pale green, clouded with a darker tint, and has a +white line on each side of the back. It feeds in May on the three trees +named for the last species, also on lime (_Tilia vulgaris_) and elm +(_Ulmus campestris_). + + +Family--LARENTIIDÆ + +This is by far the most extensive family of the _Geometræ_, containing +as it does considerably over a hundred species, or well nigh a half of +the whole group. + +The wings of the various species are smooth and more or less glossy, and +the front pair are generally crossed by several wavy lines. Many of the +moths, and particularly those known popularly as the Pugs, are very +small. Representatives of the family are to be met with almost +throughout the year--from early spring to the middle of the winter. + +Most of the caterpillars are rather long and slender, and without humps; +and green is the prevailing colour. They feed either on trees or low +plants, often protecting themselves in folded leaves; and some of the +smaller species show a decided preference for flowers and seeds. + +We shall select about a dozen of the commonest members for individual +description. + + +_The November Moth_ (_Oporabia dilutata_) + +Our first example is the November moth--a rather dingy and very variable +species that may be found almost everywhere in October and November. The +ground colour of the fore wings is dingy grey, crossed by several darker +lines, subject to considerable variations. The hind wings are paler, +with two slender darker lines parallel with the hind margin. + +[Illustration: FIG. 194.--THE NOVEMBER MOTH.] + +The caterpillar feeds on many trees, the principal of which are the oak, +whitethorn and blackthorn. Like the perfect insect, it is very variable +in colour, but is generally of a bright green, with reddish or purplish +spots on the back and sides. The spiracles are yellow or orange, and +below them is a white stripe. It is full fed in June. + + +_The Twin-spot Carpet_ (_Larentia didymata_) + +The Twin-spot Carpet is common throughout Great Britain, and the +beginner is likely to meet with it in June and July during his first +season. Our illustration represents the male, the fore wings of which +are greyish brown, crossed by several dark lines, and with a double dark +and conspicuous spot near the middle of the hind margin. The female is +much lighter, and the markings are also lighter and less distinct. + +[Illustration: FIG. 195.--THE TWIN-SPOT CARPET.] + +The caterpillar is pale green, with a narrow whitish line along the +spiracles. It feeds in April and May on the leaves of the wood anemone +(_Anemone nemorosa_), chervil (_Chærophyllum temulum_), and other +plants. + + +_The Grass Rivulet_ (_Emmelesia albulata_) + +We represent the genus _Emmelesia_ by the Grass Rivulet--a pretty little +moth that flies in June, and which is widely distributed though not +abundant. + +[Illustration: FIG. 196.--THE GRASS RIVULET.] + +Its fore wings are pale grey, crossed by several white lines, the +arrangement of which may be seen in our engraving. The hind wings are of +the same ground colour, but have no markings except a white wavy line +near the hind margin. + +The caterpillar feeds during July and August on the seeds of the yellow +rattle (_Rhinanthus Crista-galli_), protecting itself from its enemies +by spinning together the petals of the flowers; and when full grown it +changes to a chrysalis under the same cover. + + +_The Netted Pug_ (_Eupithecia venosata_) + +We now come to the enormous genus _Eupithecia_, containing about fifty +small species, most of which are known as 'Pugs.' Many of these are +only imperfectly known, there being yet much to learn about their +earlier stages. + +[Illustration: FIG. 197.--THE NETTED PUG.] + +The Netted Pug flies in May and June, and is to be found in most parts +of Great Britain. Its fore wings are brownish grey, crossed by two +zigzag light bands, both of which are bordered with black, and divided +throughout by a fine dark line. There are also other dark lines, both +transverse and longitudinal, arranged as here represented. + +The caterpillar feeds during July inside the seed capsules of campions +(_Silene Cucubalis_, _S. maritima_, _S. acaulis_, and _Lychnis diurna_) +and catchfly (_Silene gallica_ and _S. nutans_). + + +_The Narrow-winged Pug_ (_Eupithecia nanata_) + +Early in May, and frequently in April, this pretty little moth may be +seen flying about at dusk among the heather on our moors. It is one of +the first Pugs of the season, and is widely distributed, and very common +in some localities. + +[Illustration: FIG. 198.--THE NARROW-WINGED PUG.] + +Its wings are dark grey, and marked with several transverse wavy light +lines. The fringe is dark grey, spotted with white. + +The caterpillar feeds during August and September on the ling (_Calluna +vulgaris_) and heath (_Erica cinerea_ and _E. Tetralix_). + + +_The Brindled Pug_ (_Eupithecia abbreviata_) + +Our last example of the Pugs is the Brindled Pug, another early species, +appearing on the wing in March and April. It is common in most parts, +and may generally be easily obtained by searching fences and tree +trunks. + +[Illustration: FIG. 199.--THE BRINDLED PUG.] + +Its fore wings are very long in proportion. The colour is yellowish +brown, crossed by darker lines. The fore wings have a very broad band of +the ground colour, broken by two short lines, and crossed by a slender +angulated stripe. + +The caterpillar feeds on the oak in June. + + +_The Small Seraphim_ (_Lobophora sexalisata_) + +This moth is very much like the Pugs in general appearance, and is quite +as small and even smaller than some of them; but it and the other +members of its genus differ from the Pugs in that they cover their hind +wings when at rest. + +[Illustration: FIG. 200.--THE SMALL SERAPHIM.] + +The fore wings are yellowish or pale brownish grey with four paler +transverse lines, the two median ones of which are divided throughout by +a darker fine wavy line. The hind wings are grey, paler at the base, and +crossed centrally by a double darker line. This species flies in May and +June, and though apparently widely distributed, can hardly be described +as common. + +The caterpillar feeds on the white willow (_Salix alba_) and sallow (_S. +caprea_) in August and September; and the chrysalis may be found in a +silken cocoon among the fallen leaves throughout the winter. + + +_The Blue-bordered Carpet_ (_Melanthia bicolorata_) + +This same family (_Larentiidæ_) is remarkable for its large number of +pretty moths, popularly known as the 'Carpets,' many of which are +exceedingly common in our woods and gardens. + +[Illustration: FIG. 201.--THE BLUE-BORDERED CARPET.] + +Our first example of these is the Blue-bordered, which is pretty well +represented in several counties of Great Britain and Ireland. Its white +fore wings are boldly marked with a blotch of greyish brown at the base, +and another extending from the middle of the costal margin more than +halfway across. The hind margin is marked with two bluish grey bars, +separated by a white line. The hind wings are white, with a very small +dark spot, and a bluish grey margin something like that of the fore +wings. + +The caterpillar is green, with longitudinal stripes of a darker and +lighter shade. It feeds in June on the alder (_Alnus glutinosa_) and +blackthorn (_Prunus spinosa_); and when full grown it changes to a brown +chrysalis within a light silken web. + +The moth flies in July and August. + + +_The Beautiful Carpet_ (_Melanthia albicillata_) + +The Beautiful Carpet belongs to the same genus as _Bicolorata_. Its +wings are of a rich creamy white, clouded with grey along the hind +margin. The basal blotches of the fore wings are large, of a dark brown +colour, and marbled with a light tint. Near the tips of these wings is +another conspicuous blotch of the same colour, from which a delicate +wavy dark line runs to the inner margin. A small dark spot also lies +near the middle of the costal margin of each of the four wings. + +[Illustration: FIG. 202.--THE BEAUTIFUL CARPET.] + +The caterpillar is green, with a white line along the spiracles, and a +triangular reddish spot on the back of segments four to ten inclusive. +It feeds on the bramble (_Rubus fruticosus_), raspberry (_R. Idæus_), +and wild strawberry (_Fragaria vesca_). It may be found in June and +July. + +The moth flies in June. + + +_The Common Carpet_ (_Melanippe sociata_) + +The genus _Melanippe_ contains twelve species, some of which are +extremely common. One of these moths--the Common Carpet--is represented +in fig. 203. Its wings are all of a smoky-brown colour, crossed by +numerous white lines, the arrangement of which may be gathered from our +illustration better than from a written description. It is a +double-brooded insect, appearing first in May, and then again about the +end of July. + +[Illustration: FIG. 203.--THE COMMON CARPET.] + +The caterpillar is mottled with shades of brown and grey. On the back +are five or six greyish-white lozenge-shaped marks, and there are a few +white dots on the back of each segment. It feeds on the hedge bedstraw +(_Galium Mollugo_), and when full grown it changes to a chrysalis in a +light cocoon on the ground. + + +_The Silver Ground Carpet_ (_Melanippe montanata_) + +In this species the ground colour is silvery white. The bases of the +fore wings are blotched with pale brown, and a dark brownish-grey bar, +containing a black spot, crosses the middle. The hind margins of the +fore wings are faintly marked with pale brown, and lines of the same +tint, more or less distinct, cross the hind wings. + +[Illustration: FIG. 204.--THE SILVER GROUND CARPET.] + +This moth is very common in all parts of the country, and may be seen on +the wing throughout the summer. + +The caterpillar is light brown, with several longitudinal lines of +different colours. On the back of each of the segments seven, eight, and +nine is a distinct black V-shaped mark, terminating behind with a bright +red spot. It feeds on the primrose (_Primula acaulis_) in the autumn, +hybernates through the winter, and is full grown about the beginning of +April. + + +_The Garden Carpet_ (_Melanippe fluctuata_) + +Our third and last member of this genus is the Garden Carpet--a moth +that must be pretty well known to almost everybody, since it is the +commonest of all the _Geometræ_ that frequent our gardens. + +[Illustration: FIG. 205.--THE GARDEN CARPET.] + +The fore wings are pale grey or brownish, with a patch of dark greyish +brown at the base, another larger one on the middle of the costa, and a +third near the tip. The wing is usually clouded between the middle +blotch and the inner margin, and numerous fine wavy lines, more or less +distinct, cross the wing. + +This moth may be seen throughout the summer, from May to September, but +is most abundant in June and July. + +The caterpillar is extremely variable in colour, being either green, +brown, or grey, or some intermediate tint; and is marbled and dotted +with dark brown on the back. It feeds on the nasturtium (_Tropæolum +majus_), rape (_Brassica Napus_), and various other cruciferous plants; +and may be found from April to August. + + +_The Yellow Shell_ (_Camptogramma bilineata_) + +Passing over two smaller genera, we come to the beautiful little Yellow +Shell. This moth is so abundant in most parts that we arouse it at +almost every stroke while beating low bushes. + +All its wings are yellow, and crossed by numerous delicate white and +brown lines. The most conspicuous feature is the two white lines, with +dark brown edging, crossing the fore wings. + +[Illustration: FIG. 206.--THE YELLOW SHELL.] + +The caterpillar feeds by night, and is therefore seldom seen except by +those who make special nocturnal searches with the aid of a lantern or +sweep net. It devours various grasses, and hides itself among the roots +or under stones during the daytime. It is full grown in April or May. +The colour is dull pale green, with a dark green dorsal line, and two +white stripes on each side. + + +_The Small Ph[oe]nix_ (_Cidaria silaceata_) + +Again passing over a few small and less important genera, we select the +small Ph[oe]nix as the last example of this very extensive family. + +[Illustration: FIG. 207.--THE SMALL PH[OE]NIX.] + +The fore wings of this species are dark brown, paler toward the hind +margin. Most of the wing rays are generally of a pale yellowish colour, +and a variable and complicated system of whitish lines crosses the wings +near the base, and another near the hind margin. Among the latter there +is always a series of dark triangular spots, with apices pointing +towards the hind margin. + +This moth is moderately common throughout the British Isles, and is +double brooded, appearing in May and August. + +The caterpillar is green, with a row of brown spots along the middle of +the back. When full grown it changes to a chrysalis in a light web. + + +Family--EUBOLIIDÆ + +This is the last family of the _Geometræ_ we shall notice, and contains +ten species. Most of these are rather pretty moths, and all have the +tips of the fore wings more or less pointed. As a rule, too, there is a +dark streak running from the very tip of the wing for a short distance +obliquely inward. + +They are generally very light sleepers, and are easily beaten from their +hiding places during the day. + +The larvæ are not humped, and may be found feeding on low plants. + +We shall briefly examine two species. + + +_The Small Mallow_ (_Eubolia limitata_) + +This moth is pretty abundant in waste places from June to August, and is +easily obtained by lightly beating the foliage of small bushes and low +plants. + +[Illustration: FIG. 208.--THE SMALL MALLOW.] + +Its fore wings are pale brown crossed by a broad central bar, the edges +of which are darker. The hind wings are of a paler brown, and are +crossed by two or three fine wavy lines. + +Although the perfect insect is so common, the caterpillar seems to be +seldom met with. It is a grass feeder, and may be looked for in May and +June. + + +_The Treble Bar_ (_Anaitis plagiata_) + +Our last example of the _Geometræ_ is the Treble Bar, a very pretty +moth, which is illustrated in fig. 9 of Plate XII. It may be readily +identified by the aid of this coloured picture, and therefore need not +be described in words. It is pretty generally distributed throughout the +British Isles, and is in some parts a very abundant species, +particularly so in the neighbourhood of London. + +The caterpillar is brown, with paler spaces between the segments. The +dorsal line is black and interrupted, and a yellow line runs along each +side. It feeds on the leaves and flowers of the perforated St. John's +wort (_Hypericum perforatum_). + +This insect is double brooded, the moth appearing in May and August, and +remaining with us throughout the month following in each case. + + + + +CHAPTER XXI + +_THE MICRO-LEPIDOPTERA_ + + +The butterflies, and all the moths contained in the groups of the last +four chapters, are commonly spoken of as constituting the +_Macro-lepidoptera_; but in addition to these there are many hundreds of +small British moths that represent what is known as the +_Micro-lepidoptera_. + +It is not usual for young entomologists to have much to do with the +'Micros' until they have had a little practical experience with the +larger species; in fact, a good number of them never seem to extend +their knowledge beyond the limits of the 'Macros' except that they may +make an occasional capture of a Micro that happens to fly across their +path. + +Now, since it would be practically impossible to deal fairly, even in +outline, with both these divisions of the _Lepidoptera_ in a work of the +present dimensions, I have devoted most space to the larger species so +as to meet the probable requirements of the majority of my readers. But +in order that the beginner may also have the means of introducing +himself intelligently to a study of the 'Micros,' I shall set apart this +chapter for a simple account of the broad principles of their +classification, illustrated by means of a few types, so that the +collector may at least know _something_ of the insects he captures, even +though he may not be able at once to fix on their names. + +The young entomologist, thus provided with the broad features that +enable him to roughly classify the specimens which reach his cabinet, +may, as his store increases, pay an occasional visit to a public museum +or the private collection of an entomological friend, and so obtain the +names and other details he may require. + +The _Micro-lepidoptera_ are divided into five main groups--_Pyralides_, +_Pterophori_, _Crambi_, _Tortrices_, and _Tineæ_, each of which is +divided into families and genera, as we have seen in the case of the +'Macros.' + + +_Pyralides_ + +The _Pyralides_ may be easily distinguished by the proportionately long +fore wings, long legs, and elongated abdomen. Some of them have wings of +a pearly lustre, and are accordingly known popularly as the 'Pearls.' +Some species fly in bright sunshine, others appear on the wing before +sunset, and fly till dusk; others, again, are purely nocturnal in their +habits. All, however, are apparently light sleepers, and may be easily +beaten out of their resting places and netted by day. Some of these +moths are common everywhere, but the majority of them are very local, +though they may be extremely abundant where they occur. + +The larvæ have a glossy and bristly appearance, and are generally +gregarious in their habits. + +This group contains about eighty species, arranged in five families as +follows: + + 1. _Pyralididæ_, including about forty species. + 2. _Botydæ_, about thirty species. + 3. _Steniiadæ_, containing only five species. + 4. _Hydrocampidæ_, four species. + 5. _Acentropodidæ_, containing only one. + + +_The Tabby_ (_Aglossa pinguinalis_) + +The first of these families contains the Tabby or Grease Moth, commonly +met with both in the larval and perfect states in barns and stables. + +[Illustration: FIG. 209.--THE TABBY OR GREASE MOTH.] + +Its fore wings are brownish grey, crossed with zigzag darker lines, and +having a black spot near the centre of the costal margin. The term +'Tabby' has been applied on account of the fancied resemblance of the +transverse markings to the fur of a tabby cat, and the other popular +name was given under the belief that the caterpillar feeds on fatty +matter, but it is extremely doubtful whether this supposition is +correct. + +The caterpillar probably feeds exclusively on the vegetable +accumulations that lie in the undisturbed corners and crevices of +outhouses and stables, and lives concealed in silken tubes, strengthened +outside by fragments of hay, chaff &c. that have been spun together. It +feeds from September to April, except during very severe weather, and +when full grown it leaves its tube, and changes to a chrysalis in a +light silken cocoon in some secluded corner. + +The moth emerges in July. + + +_The Meal Moth_ (_Pyralis farinalis_) + +The same family contains the common Meal Moth, so called because in the +larval state it feeds on meal and allied substances. + +[Illustration: FIG. 210.--THE MEAL MOTH.] + +The fore wings are yellowish grey, with reddish basal patches, a broad +reddish band along the hind margin, and two whitish indented transverse +lines. The hind wings are grey, and are crossed by two lines similar to +and continuous with those of the front pair. + +This moth is to be found in abundance throughout the summer months in +places where corn, meal, and grain are stored in large quantities, +sitting on walls and rafters during the daytime, and taking to flight in +the evening. + +The caterpillar feeds on corn, meal, grain, bran, &c., and lives +concealed in a silken tube covered outside with particles of its food +substance. It is not fully grown till nearly two years old, and then +changes to a chrysalis in a white silken cocoon. + + +_The Small Magpie_ (_Eurrhypara urticata_) + +The family _Botydæ_ contains the moths that are popularly known as the +'Pearls' on account of the pearly lustre of the wings. One of its +species--the Small Magpie--is shown in the accompanying illustration. +Its fore wings are pearly white, with blackish hind margin, a yellow +streak at the base, and blackish markings, the arrangement of which may +be seen in the figure. + +[Illustration: FIG. 211.--THE SMALL MAGPIE.] + +It is a very common moth, flying at dusk during June and July in waste +places where the stinging nettle grows. + +The caterpillar is whitish, with a dark dorsal line. It feeds on the +stinging nettle (_Urtica dioica_), always remaining concealed between +leaves which it has spun together with silken threads. + + +_The Mother-of-Pearl_ (_Botys ruralis_) + +This is another very common species of the family _Botydæ_, abundant +almost everywhere, and to be found on the wing from June to August. + +Its wings are whitish, and exhibit a very decided pearly lustre, and all +the markings are of a dull dark grey. + +[Illustration: FIG. 212.--THE MOTHER-OF-PEARL.] + +The caterpillar is glossy, and has a semi-transparent appearance. It is +greenish white above, with a darker line down the back; and the sides +are of a brighter green. It feeds on the stinging nettle (_Urtica +dioica_) during May. + + +_The Garden Pebble_ (_Pionea forficalis_) + +The same family contains also the Garden Pebble, which is one of the +commonest frequenters of gardens, both in town and country. + +The fore wings are pale yellowish grey with brown markings. The latter +include a fine line from the tip to the middle of the inner margin, and +another paler one inside and parallel with this, having a dark spot near +its centre. The hind wings are lighter, and have a pale and interrupted +line parallel with the hind margin. + +[Illustration: FIG. 213.--THE GARDEN PEBBLE.] + +The caterpillar is pale greenish, with a dark line along the back and on +each side. It feeds on the cabbage and other cruciferous plants. + +The moth flies from May to the end of the summer, and the caterpillar +may be found about midsummer, and again in the autumn. + + +_The Beautiful China Mark_ (_Hydrocampa stagnata_) + +Our last example of the _Pyralides_--the Beautiful China Mark--belongs +to the family _Hydrocampidæ_. This small family is remarkable for the +fact that its four species spend their larval state in the water, +feeding on the under surfaces of the leaves of water lilies and other +aquatic plants. These curious larvæ live either in cases which they +construct for their protection, something after the fashion of the larvæ +of caddis flies, or quite free in the water, and then they are supplied +with special breathing organs that enable them to absorb the oxygen held +in solution in the water. + +[Illustration: FIG. 214.--THE BEAUTIFUL CHINA MARK.] + +The moth we have selected for illustration is a very common species, and +may be seen flying in great numbers in the neighbourhood of ponds during +June and July. + + +_The Pterophori_ + +The members of this remarkable group are easily distinguishable from all +other moths by the feathery appearance of their wings, a feature that +has gained for them the popular name of _Plume Moths_. Their fore wings +are more or less divided or cleft, and their hind wings are generally +divided into three distinct feathery plumes. + +The larvæ are hairy, and when full fed they suspend themselves by their +anal claspers, and change to the chrysalis state without any kind of +covering. They are generally to be found in spring and early summer, but +some of them feed in the autumn. + +The chrysalides are often hairy, though some of them are perfectly +smooth. + +Plume moths are to be met with more or less throughout the year. Many of +the earlier species appear on the wing in spring and early summer; but +the late feeders emerge in the autumn, and hybernate through the winter, +often taking to the wing on the mild days of our coldest months. + +The _Pterophori_ include only about forty British species, all of which, +with two exceptions, belong to the family _Pterophoridæ_. The two +exceptions represent as many families--one the _Chrysocorididæ_, and the +other the _Alucitidæ_. + + +_Platyptilia gonodactyla_ + +This is one of the commonest of the _Pterophoridæ_, generally appearing +in our gardens and in waste places towards the end of May, and +continuing with us for some time. It starts from its retreat at or +before sunset, and remains on the wing after dark. + +[Illustration: FIG. 215.--GONODACTYLA.] + +Its fore wings are ochreous grey, with a narrow brown costal margin, and +a triangular brown patch on the costa. Beyond this patch the wing is +cleft. The hind wings consist of three distinct brownish plumes, the +third of which has a small tuft of black scales projecting from the +middle of the inner margin. + +The caterpillar feeds on the flower stalks of the coltsfoot during March +and April. + + +_Leioptilus osteodactylus_ + +This is another species of the same family. It is not uncommon, but is +more local than the last. + +[Illustration: FIG. 216.--OSTEODACTYLUS.] + +Its fore wings are pale yellow, with a small brown dot at the +commencement of the dividing fissure, and a brown blotch on the costal +margin nearer the tip. The hind wings are divided into three distinct +plumes like those of _Gonodactyla_. + +This is a later species, appearing on the wing in July. + + +_Aciptilia pentadactyla_ + +The fore wings of this species are white, frequently with a few greyish +scales, and are deeply divided into two feathery plumes. The hind wings +are pure white, and consist of three plumes. + +[Illustration: FIG. 217.--PENTADACTYLA.] + +This pretty insect is common and widely distributed, and flies during +June and July. + +The caterpillar feeds on the convolvulus in May. + + +_Alucita hexadactyla_ + +Our last example of the _Pterophori_ is the Twelve-plume Moth, the only +British representative of the family _Alucitidæ_. + +This little insect is of a yellowish colour, with two dark bands across +the fore wings; and both fore and hind wings are divided into six +distinct feathers. It is a common moth, and frequents sheltered spots, +flying at dusk. It appears in August, remains on the wing till October, +and then hybernates till the following April. During the winter it is +commonly met with in outhouses and even in dwelling houses. + +[Illustration: FIG. 218.--HEXADACTYLA--ENLARGED.] + +The caterpillar feeds during June and July on the flower buds of the +honeysuckle (_Lonicera Periclymenum_). It is not hairy, like most of the +larvæ of the last family; and, unlike these, it changes to a chrysalis +in a silken cocoon. + + +_Crambi_ + +The third group of the 'Micros' is the _Crambi_, and contains about +eighty species, arranged in four families. + +Some of them are common moths with which all must be more or less +familiar, as they are roused from the grasses on which they repose at +almost every footstep as we walk through meadows in the summer. When at +rest, they present a very peculiar appearance. Their wings are wrapped +closely round their bodies in such a manner that they are hardly +distinguishable from the stems on which they repose. + +The larvæ have sixteen limbs, and are very variable in their habits. +Some feed among moss or dry stems in silken tubes, some on the stems of +reeds, and others inhabit the hives of bees and feed on the wax of the +honeycomb. + +The four families are: + +1. _Chilidæ_--five species. + +2. _Crambidæ_--about thirty species. + +3. _Phycidæ_--over forty species. + +4. _Galleridæ_--five species. + + +_Chilo Phragmitellus_ + +This species is one of those moths known as the 'Veneers,' and is +popularly termed the Wainscot Veneer. It is one of the largest of the +family _Chilidæ_. + +Its fore wings are long, narrow, and pointed at the tip. They are of a +pale ochreous brown colour, with a row of small black dots along the +hind margin. + +The caterpillar is pale grey, with brown stripes; and the head and +second segment are yellowish brown. It feeds on the common reed +(_Phragmites_) in the autumn, and hybernates till the following spring, +when it resumes its feeding. + +[Illustration: FIG. 219.--PHRAGMITELLUS--ENLARGED ONE-HALF.] + +This insect is rather local, but may be searched for in all marshy +places where reeds abound. + + +_Crambus hamellus_ + +The family _Crambidæ_ is represented by the above-named species, which +has the popular title of Pearl-streak Veneer. It is not a common moth, +but is to be obtained in some localities by beating low herbage. + +[Illustration: FIG. 220.--HAMELLUS--SLIGHTLY ENLARGED.] + +Its fore wings are ochreous and glossy, with a silvery streak from the +base, running almost parallel with the costal margin. The hind margin is +yellow, bordered inside by a wavy brown line. The hind wings are pale +greyish brown with a yellowish margin. + + +_Crambus tristellus_ + +The same family contains the species _Tristellus_, which, unlike the +preceding insect, is abundant everywhere. + +[Illustration: FIG. 221.--TRISTELLUS.] + +Its fore wings are generally yellowish brown, but exceedingly variable. +A pale streak runs from the base to just beyond the middle of the wing, +and is then forked. Near the hind margin is a very indistinct brown wavy +line. The hind wings are dull smoke colour with a light fringe. As with +the other moths of the family, its labial palpi are very long. + +The moth flies from July to September. + + +_Crambus hortuellus_ + +This is also an abundant species, to be met with everywhere during June +and July. + +Its fore wings are dull ochreous brown. The wing rays are whitish near +the inner margin, and a brown line with a silvery edging crosses near +the hind margin. The hind wings are dull smoky brown, with a shining +surface, and the fringe is light. + +[Illustration: FIG. 222.--HORTUELLUS.] + +The larva is pale grey with dark grey spots, and may be found among moss +in April and May. + + +_Galleria mellonella_ + +Our last example of the _Crambi_ is a moth that the young entomologist +is not likely to meet with unless he happens to be in the neighbourhood +of one of its haunts, but its habits are so peculiar that we are tempted +to introduce it on that account. + +[Illustration: FIG. 223.--MELLONELLA.] + +It belongs to the family _Galleridæ_, the larvæ of which feed on the wax +combs in the hives of bees and in the nests of wild bees. They are +protected from the stings of the inmates by silken tubes which they +construct, and by the hardened covering of their heads and front +segments--the only parts that remain exposed while they are feeding. + +The fore wings of the moth are reddish-grey or brownish, sometimes with +a greenish tinge, and yellowish along the inner margin. The hind wings +are greyish brown. + +It flies in July and August, and the caterpillar feeds in May and June. + + +_The Tortrices_ + +This is a large group of moths, deriving their name from the peculiar +habit of a number of the larvæ of twisting or rolling up leaves for +their protection. This habit, however, is not common to all, for some +feed on stems and flowers, and others devour seeds and fruits. + +The perfect insects may easily be known by the shape of the wings. The +fore pair are gracefully curved on the costal margin in such a way that, +when the insect is at rest with its wings closed, its outline is much +the shape of a bell. + +The identification of the various species of this extensive group is no +easy task, for many of them are so variable in their colouring that +insects of the same species are often very different from each other. +So puzzling indeed is this tendency to run into varieties that many +insects, once considered to belong to separate species, have been +reduced to one; and this has been the case in a number of instances. + +There are so many of these little moths that we cannot even give a +representative of each family, but the following outline will serve to +show the extensiveness of the group. + + Family 1. _Tortricidæ_, about sixty species. + " 2. _Penthinidæ_, " twenty " + " 3. _Spilonotidæ_, " twelve " + " 4. _Sericoridæ_, " twenty-seven species. + " 5. _Sciaphilidæ_, " twenty-four " + " 6. _Grapholithidæ_, about one hundred and fifty species. + " 7. _Pyraloididæ_, four species. + " 8. _Conchylidæ_, about fifty species. + " 9. _Apheliidæ_, three species. + +We shall now briefly examine a few of the commonest insects of the +group. + + +_Tortrix xylosteana_ + +This pretty moth is common in most parts, and may often be met with in +abundance in wooded localities during July. It belongs to the family +_Tortricidæ_. + +Its fore wings are ochreous brown. A very dark oblique streak, edged +with yellow, runs from the inner margin of the base. A reddish patch in +the centre of the wing, also edged with yellow, is narrow on the costa, +and expands as it approaches the inner margin. Beyond this are another +dark patch on the costa and two reddish-brown blotches on the hind +margin. + +[Illustration: FIG. 224.--XYLOSTEANA WITH WINGS CLOSED.] + +The larva is greenish brown, marked with white spots which have black +centres; and it feeds on oak (_Quercus Robur_), honeysuckle (_Lonicera +Periclymenum_), and other plants, in the month of May. + + +_Tortrix viridana_ + +In June and July this pretty but destructive little insect may be seen +flying in abundance in almost every oak wood. Its fore wings are one +uniform pale green with the exception of a streak of yellow along the +costal margin; and, when at rest, scores may exist on a single twig +without being seen unless closely examined. The hind wings are of a pale +smoky tint, and rather glossy. + +The larva is green, with black spots, and feeds in May and June on the +oak and other trees, often almost completely devouring the foliage. + +[Illustration: FIG. 225.--VIRIDANA.] + + +_Peronea cristana_ + +This moth is not so generally abundant, but is very common in many of +the woods of the south. It is remarkable for the large number of +varieties that have been observed, many of which have been regarded as +distinct species. + +[Illustration: FIG. 226.--CRISTANA--ENLARGED.] + +Its fore wings are of some shade of brown or grey, with a light streak +of variable colour along the inner margin, and a tuft of raised white +scales in the middle of the wing. + +It flies during August and September. + + +_Ptycholoma lecheana_ + +Our last example of the family _Tortricidæ_ is _Lecheana_, a moth that +is common in most parts in June and July. + +[Illustration: FIG. 227.--LECHEANA.] + +Its fore wings are brown, lighter towards the base. There are no very +distinct markings, but there is generally a darker patch in the middle +of the wing, edged with a silvery streak on each side. + +The larva feeds on several trees, including oaks and elms, in the month +of May. + + +_Penthina pruniana_ + +[Illustration: FIG. 228.--PRUNIANA.] + +The next family--_Penthinidæ_--contains the common species _Pruniana_, +which may be readily known by its boldly marked wings. The basal portion +of the fore wings, to the extent of nearly two-thirds of the whole, is +very dark brown. The remaining third is almost white, and clouded with +grey. The hind wings are smoky brown with a paler fringe. + +The caterpillar of this species feeds on the blackthorn (_Prunus +spinosa_) in May, and the moth flies in June and July. + + +_Antithesia salicella_ + +This moth is not nearly so common as the last species, but is fairly +plentiful in some localities in the south of England. It belongs to the +same family as _Pruniana_. + +[Illustration: FIG. 229.--SALICELLA.] + +The fore wings are whitish at the base and along the inner margin, but +the light tint is dotted and clouded with shades of brown. The remainder +of the wings is marbled with dark brown of different depths, relieved +near the hind margin with a little blue. The hind wings, as is usual +with the _Tortrices_, are dull smoky brown. + +The caterpillar is reddish brown with black spots, and feeds during May +in rolled leaves of willows. + +The moth flies in August and September. + + +_Sciaphila octomaculana_ + +Our single example of the family _Sciaphilidæ_ is the species +_Octomaculana_, which, though not very abundant, is widely distributed, +and moderately common in parts. + +Its fore wings are white, dusted with grey, and each is marked with four +dark grey patches which have given rise to its specific name--a word +which signifies 'eight-spotted.' The hind wings are grey. + +[Illustration: FIG. 230.--OCTOMACULANA--ENLARGED.] + +The caterpillar feeds on thistles and other plants, and the moth flies +from August to October. + + +_Ephippiphora cirsiana_ + +This insect represents the family _Grapholithidæ_. It is a common moth, +and is widely distributed. + +Its fore wings are greyish brown, with a large white patch on the middle +of the inner margin; and beyond this white, in the anal angle, is a +pale grey patch containing three or four black dots. The tips of the +wings are reddish brown. + +The moth flies in June and July; and the larva, which feeds on thistles, +may be found in the stems from October to the following May. + +[Illustration: FIG. 231.--CIRSIANA--ENLARGED.] + + +_Carpocapsa pomonella_ + +The same extensive family contains a few moths that are very destructive +to our fruits, the larvæ burrowing into and living entirely within their +substance. One of these--_Pomonella_--is popularly known as the Codlin, +as its larva is so often found in the interior of small apples of the +same name. + +[Illustration: FIG. 232.--POMONELLA.] + +The fore wings of this insect are grey, with a number of dark transverse +lines. The spot in the anal angle is edged with a coppery tint, and +inclosed by a curved black line. + +This moth is common in all parts, flying during June and July; and the +larva may be looked for in apples and pears in August and September. + + +_Xanthosetia zoegana_ + +Our last example of the _Tortrices_ is _Zoegana_, which belongs to the +family _Conchylidæ_. Its fore wings are yellow, with a reddish streak +along the costa near the base, and a small reddish spot opposite this +near the inner margin. The tip of the wings is dark reddish brown, in +the middle of which is a large yellow spot. + +[Illustration: FIG. 233.--ZOEGANA--ENLARGED.] + +This moth is widely distributed, and in some parts common. It flies from +May to August, and the larva feeds on the small scabious (_Scabiosa +columbaria_). + + +_The Tineæ_ + +We have noticed that the _Tortrices_ form a very extensive group of +moths, but they are far outnumbered by the _Tineæ_, for of these there +are over seven hundred known British species. + +Of course, among so many species we are sure to find considerable +variety in form and structure; but notwithstanding this, the _Tineæ_ +form a well-marked division, and the beginner will find but little +difficulty in distinguishing between these and the other Micros. + +The wings are long and narrow, and are remarkable for the length of the +fringe, particularly that of the hind wings. The bodies, too, are long +and slender. + +The larvæ are exceedingly variable. Some have the usual number of +sixteen limbs, and others have as many as eighteen. Again, the larvæ of +several genera have only fourteen legs, and some are absolutely legless. + +With regard to their food and habits, they are equally variable, for +while some feed exposed, others are always protected in rolled leaves. +Some construct for themselves portable tubes, so that they always remain +under cover, and are at the same time perfectly free to ramble in search +for food. Some, also, are leaf miners; and the group includes the +so-called 'Clothes Moths,' whose larvæ devour our garments, furs, and +the upholstering of our furniture. + +We shall now briefly notice a few species, in order that we may become +better acquainted with the general characters of the group. + + +_Diurnea fagella_ + +This moth represents the small family _Epigraphiidæ_, containing only +six species, all of which appear in the winter or early spring. + +The present species is very common in most parts, and may be seen at +rest on the barks of trees in March and April. + +[Illustration: FIG. 234.--FAGELLA.] + +The fore wings are usually pale grey or yellowish grey, and dotted with +brown; but there is a great variety both in the depth of the ground +colour and the distinctness of the markings. Our illustration gives the +usual appearance of the insect. + +The caterpillar feeds on various trees in September and October, always +protected between leaves that it has spun together. + + +_Adela cuprella_ + +The family _Adelidæ_ contains ten species, all remarkable for the great +length of their antennæ. The one selected for illustration is a +beautiful little moth with bright bronzy green fore wings, tinged with a +rich glossy violet. The hind wings are brown with a glossy surface. + +[Illustration: FIG. 235.--CUPRELLA.] + +This moth does not seem to be widely distributed, but is fairly +plentiful where it occurs. Wimbledon Common and Epping Forest are good +localities for it. It is on the wing in April and May. + + +_Hyponomeuta Padellus_ + +The family _Hyponomeutidæ_ contains about twenty insects, some of which +are very common and exceedingly destructive to our trees. In May and +June hawthorn and fruit trees may be seen swarming with the gregarious +larvæ of some of them, and almost entirely stripped of their leaves. + +[Illustration: FIG. 236.--PADELLUS.] + +The species here figured has grey or white fore wings with three rows of +black dots. The hind wings are darker grey without dots. + +The larva feeds on hawthorn, apple, and other trees. The perfect insect +flies in July and August. + + +_Depressaria nervosa_ + +The next family--_Gelechiidæ_--is represented by the species Nervosa, +which is common in many localities. + +[Illustration: FIG. 237.--NERVOSA--TWICE NATURAL SIZE.] + +Its fore wings are reddish brown, and are marked by a number of short +longitudinal streaks of a darker colour. The hind wings are light grey. + +The caterpillar is black, marked with black spots in white rings, and +having yellow side stripes. It feeds on the flowers of the hemlock +water dropwort (_[OE]nanthe crocata_) during June and July. + +The moth flies in August and September. + + +_Harpella Geoffrella_ + +The same extensive family contains the moth Geoffrella, represented in +the accompanying cut. This is an exceedingly pretty insect. The basal +portion of its fore wings is yellow, with two longitudinal dark streaks, +the outer one of which is bent towards the inner margin near the middle +of the wing. The remaining portion of the wings is brown, with two +yellowish triangular spots, one on the costal and one on the inner +margin. On the middle of the costa is a short dark streak. + +[Illustration: FIG. 238.--GEOFFRELLA.] + +This moth appears in May and June, and is rather local, but very +abundant in some parts. + + +_Coleophora ibipennella_ + +The family _Coleophoridæ_ contains about seventy small moths, +characterised by their very narrow and pointed wings, with long fringes, +and also, generally, by a little tuft of hair on the first joint of the +antennæ. + +[Illustration: FIG. 239.--IBIPENNELLA--ENLARGED.] + +The larvæ live in little cases which they construct, and feed on various +leaves and seeds. They spend the winter within their cases, and change +to the chrysalis state in spring or early summer. + +One of these moths--_Ibipennella_--is shown in fig. 239. Its fore wings +are white, with a satiny gloss, and brownish towards the tips. The +'nervures' are generally of a yellowish tinge. The hind wings are dark +grey. + +The larva feeds on the birch (_Betula alba_), and may be seen walking on +the surface of the leaves, carrying, or rather dragging after it, the +pistol-shaped case in which it lives, nothing protruding save its head +and front legs. It is full fed in May, and the moth flies in July. + + +_Tischeria complanella_ + +This species represents the rather extensive family _Elachistidæ_, the +members of which have narrow and pointed wings. Many of them are adorned +with beautiful metallic tints, but are generally so small that a lens is +necessary to show up the splendour of their clothing. Most of the larvæ +are leaf miners, and are easily reared. All that is necessary is to +pluck a few twigs, the leaves of which, when held up to the light, +reveal the tiny larvæ in their burrows, and place them in a vessel of +water. They do not feed long, and it is probable that most of the larvæ +so treated will be ready to change before the leaves have become dry. +The present species has bright yellow fore wings, with pale grey +cloudings at the hind margins. It is very abundant in many parts, and +flies during the month of June. + +[Illustration: FIG. 240.--COMPLANELLA--ENLARGED.] + +The larva is one of the numerous leaf miners, and is of a yellowish +colour. It feeds in oak leaves during the autumn, and its presence is +indicated by light blotches on the foliage. + + +_Nepticula aurella_ + +The family _Nepticulidæ_--the last of the _Tineæ_--contains a number of +little moths, including the smallest of the _Lepidoptera_. Many of them +are exceedingly beautiful, being decorated with various tints of a +splendid metallic lustre, but their beauty is revealed only by the use +of a magnifying lens, and they are so small that very great care and +patience is required to set them properly. + +They may be recognised by their short and thick antennæ, rather large +head, broad fore wings, and narrow pointed hind wings. + +The larvæ have no true legs, but have nine pairs of very imperfectly +developed claspers. They are leaf miners, and are sometimes so abundant +that several may be found in a single leaf. + +[Illustration: FIG. 241.--AURELLA--ENLARGED.] + +The species we have selected has fore wings of a rich golden brown, with +deep violet tips, and a broad bar of pale golden yellow beyond the +middle. It may be found throughout the spring and summer. The larva +excavates long irregular burrows in the leaves of the bramble. + + + + +APPENDICES + + +APPENDIX I + +I have previously called the reader's attention to our classified list +of butterflies and moths, and have hinted at one or two of the objects +for which it is inserted. It contains the scientific and popular names +of all the British Butterflies, _Sphinges_, _Bombyces_, _Noctuæ_, and +_Geometræ_, arranged in their various families and genera; and in cases +where two specific names are commonly applied to the same insect, both +are given. + +Its chief uses to the young entomologist are to show the relation which +the insects bear one to another, and to supply a guide for the proper +arrangement of the specimens in his cabinet. + +The order adopted is that of South's 'Synonymic List of British +Lepidoptera,' and it has already been mentioned that similar lists, +printed on one side of the paper only, may be obtained from dealers in +naturalists' appliances. These, cut up as required, supply very neat +labels for cabinets or store boxes. + + +_COMPLETE CLASSIFIED LIST OF BRITISH MACRO-LEPIDOPTERA_ + +=RHOPALOCERA (BUTTERFLIES).= + + PAPILIONIDÆ. +

on his knowledge of the times at which the various butterflies +and moths generally appear, and of the localities which they are known +to frequent. The experiences he has gained in the past enable him to +calculate on the probabilities of the future, and he chooses both time +and locality according to his requirements. + +As he makes his way to the hunting ground he counts over the chances of +meeting with a certain insect that is wanted to fill a long-standing +blank in his cabinet; and we hear him discussing the probabilities as to +whether this species is yet 'out,' or whether the larvæ of that species +are feeding. + +How different it is with the young and unguided entomologist! He rambles +promiscuously here and there, having only the faintest idea as to what +he is likely to see, and perhaps meeting with only four or five species +when an experienced collector, without covering a larger area of ground, +would take scores in the same time. + +In order to afford some little help to the beginner, I have thought it +advisable to introduce a calendar of operations to guide him in his +work. The space at our command would not allow this to be carried out in +detail, but the general instructions will undoubtedly assist most of my +readers until the practical experience gained by a few years' work has +enabled them to run on their own legs. + +Of course, in making reference to the monthly lists of insects on the +wing, allowance must be made for the forwardness or backwardness of the +seasons. Thus, an insect entered in the April list _may_ appear in March +in an exceptionally warm season, but may not emerge till the early part +of May if the spring has been unusually severe. + +It will be observed that in cases where all the species of a certain +genus or family appear on the wing in the same month, the name of that +genus or family is entered on the list instead of the names of the +individual species; but the latter can easily be obtained by reference +to Appendix I. + + +JANUARY + +There is not much field work to be done during this month. If the +weather is very severe, hardly an insect will be found on the wing; but +a mild January will sometimes entice the Brimstone Butterfly (_Rhamni_) +and some of the hybernating Vanessas from their winter quarters. + +Hybernating moths may also be met with, on the wing if the weather +is mild, or sleeping in their sheltered nooks during the frosts. +These include several _Noctuæ_--_Auricoma_, _Lithargyria_, +_Suffusa_, _Vaccinii_, _Spadicea_, _Erythrocephala_, _Satellitia_, +_Rubiginea_, _Croceago_, _Vetusta_, _Exoleta_, _Ornithopus_, +_Furcifera_, _Semibrunnea_, _Socia_, and _Libatrix_; and also a few +_Geometræ_--_Zonaria_, _Fluviata_, _Dubitata_, _Siterata_, and _Miata_. + +In addition to these hybernating insects, the collector may examine tree +trunks and fences for the Early Moth (_Rupicapraria_), and late +specimens of the Winter Moth (_Brumata_); and towards the end of the +month he may expect to meet with fresh specimens of the Pale Brindled +Beauty (_Pedaria_) and the Spring Usher (_Leucophæaria_). A few of the +_Tineæ_ may also be seen. + +The net need not be used at all during the colder months of the year, as +the moths are easily taken in pill boxes from the trunks and fences on +which they rest. + +Pupa digging may be carried on throughout the month if the weather is +sufficiently mild, but it is of no use attempting this during a frost. +Hybernating larvæ may also be searched out of their winter quarters if +the collector does not mind giving them the attention they require; but, +as a rule, it is better to wait till they themselves start out to feed +in the spring, at which time all their food plants are showing leaf. + + +FEBRUARY + +Our remarks under 'January' concerning pupa digging and other work apply +equally well to this month. The same hybernating butterflies and moths +may be looked for; and, in addition to _Pedaria_, _Leucophæaria_, and +_Rupicapraria_, which now appear more plentifully, the following species +will probably be seen: + + Small Eggar (_Lanestris_) + Small Brindled Beauty (_Hispidaria_) + Oak Beauty (_Strataria_) + Dotted Border (_Marginaria_) + March Moth (_Æscularia_) + +About half a dozen species of the _Tineæ_ will also have made their +appearance before the end of the month. + + +MARCH + +Many of the hybernating larvæ will come out during March if the weather +is mild, and commence to feed; and the young caterpillars will begin to +appear from the eggs of the early moths already named. This is +consequently a good time to commence the search for larvæ if you intend +to go in for rearing. During the daytime some may be beaten from the +boughs of trees and shrubs; and those which feed on low plants, being +generally nocturnal in their habits, should be searched for in the +evening, after dark, with the aid of a lantern. + +The hybernating butterflies are now flying more freely than before, and, +if the weather is bright and warm for the time of year, a few freshly +emerged species may be seen. These may possibly include: + + Large White (_Brassicæ_) + Small White (_Rapæ_) + Green-veined White (_Napi_) + Holly Blue (_Argiolus_) + +As regards moths, several fresh species may be expected to appear, while +those named as appearing in February are still to be found. The +new-comers may include: + + =Bombyces.= + Kentish Glory (_Versicolor_) + Yellow-horned (_Flavicornis_) + + =Noctuæ.= + Pine Beauty (_Piniperda_) + White-marked Rustic (_Leucographa_) + Red Chestnut (_Rubricosa_) + All species of the genus _Tæniocampa_ + Early Grey (_Areola_) + Green-brindled Dot (_Oleagina_) + Orange Underwing (_Parthenias_) + Light Orange Underwing (_Notha_) + + =Geometræ.= + Early Thorn (_Bilunaria_) + Engrailed (_Biundularia_) + Mottled Grey (_Multistrigaria_) + +Sugaring may be commenced towards the end of March, and sallow blossom +may be searched in the evening, but it is probable that only a few +species will be taken by these means. + +A few more species of the _Tineæ_ appear in March, and four or five of +the _Tortrices_ are out before the end of the month. + + +APRIL + +This is really a busy month with the entomologist, and it will be +necessary to put all apparatus and appliances into perfect order early. +The cyanide bottle should be freshly charged, nets examined and repaired +if necessary, and all setting boards, breeding cages &c. put in perfect +trim for the new season's work. + +Larvæ are now feeding freely, and a few hours spent in beating, +sweeping, and searching will enable you to stock your cages liberally. + +Sugaring may be continued throughout the month, and the sallow blossom +may be searched as long as it proves attractive. Moths may also be +attracted by light at night. + +The following butterflies are generally out during April, in addition to +the hybernated species already named: + + Large White (_Brassicæ_) + Small White (_Rapæ_) + Green-veined White (_Napi_) + Orange Tip (_Cardamines_) + Wood White (_Sinapis_) + Pearl-bordered Fritillary (_Euphrosyne_) + Speckled Wood (_Egeria_) + Green Hairstreak (_Rubi_) + Small Copper (_Phl[oe]as_) + Holly Blue (_Argiolus_) + Grizzled Skipper (_Malvæ_) + Dingy Skipper (_Tages_) + +The following is a list of the principal moths for April: + + =Bombyces.= + Small Lappet (_Ilicifolia_) + Kentish Glory (_Versicolor_) + Yellow Horned (_Flavicornis_) + Frosted Green (_Ridens_) + + =Noctuæ.= + Pine Beauty (_Piniperda_) + White-marked Rustic (_Leucographa_) + Red Chestnut (_Rubricosa_) + All species of the genus _Tæniocampa_ + Early Grey (_Areola_) + Mullein Shark (_Verbasci_) + Orange Underwing (_Parthenias_) + Light Orange Underwing (_Notha_) + + =Geometræ.= + Brimstone (_Luteolata_) + Early Thorn (_Bilunaria_) + Belted Beauty (_Zonaria_) + Brindled Beauty (_Hirtaria_) + Waved Umber (_Abruptaria_) + Small Engrailed (_Crepuscularia_) + Engrailed (_Biundularia_) + Sloe Carpet (_Pictaria_) + Netted Mountain (_Carbonaria_) + Mottled Grey (_Multistrigaria_) + Satyr Pug (_Satyrata_) + Marbled Pug (_Irriguata_) + Campanula Pug (_Campanulata_) + Brindled Pug (_Abbreviata_) + Oak-tree Pug (_Dodoneata_) + Double-striped Pug (_Pumilata_) + Early Tooth-striped (_Carpinata_) + Shoulder Stripe (_Badiata_) + Many-lined (_Polygrammata_) + Tissue (_Dubitata_) + +In addition to the above, a few species of the _Tortrices_, several of +the _Tineæ_, and one or two of the Plume Moths (_Pterophori_) are out +during April. + + +MAY + +Little or nothing will be obtained by digging during May, yet a number +of pupæ may be found among grass and leaves under trees, and also +attached to the leaves and stems of low plants.

Many moths are driven from their resting places early in the +morning by the direct rays of the rising sun, and then seek out a spot +where they are better sheltered, and where they are consequently less +easily found. Hence the advantage of searching fences early in the +morning. + +The May list includes: + + =Sphinges.= + Small Elephant (_Porcellus_) + All species of the genera _Smerinthus_ and _Macroglossa_ + Some of the Clearwings (_Apiformis_, _Sphegiformis_, and + _Culiciformis_) + Cream-bordered Green (_Chlorana_) + Green Silver-lined (_Prasinana_) + + =Bombyces.= + Wood Tiger (_Plantaginis_) + Muslin Moth (_Mendica_) + Common Swift (_Lupulinus_) + Pale Tussock (_Pudibunda_) + Small Lappet (_Ilicifolia_) + Emperor (_Pavonia_) + All species of family _Drepanulidæ_ + Alder Kitten (_Bicuspis_) + Puss (_Vinula_) + Several of the 'Prominents' (_Cuculla_, _Carmelita_, _Dictæa_, + _Dictæoides_, _Trilophus_, _Ziczac_, _Trepida_, _Chaonia_, + _Trimacula_) + Chocolate Tip (_Curtula_) + Small Chocolate Tip (_Pigra_) + + =Noctuæ.= + Knot Grass (_Rumicis_) + Sweet Gale (_Myricæ_) + White Colon (_Albicolon_) + Cabbage (_Brassicæ_) + Treble Lines (_Trigrammica_) + Marsh Moth (_Palustris_) + Light Brocade (_Genistæ_) + Mullein Shark (_Verbasci_) + Betony Shark (_Scrophulariæ_) + Starwort Shark (_Asteris_) + Camomile Shark (_Chamomillæ_) + Small Dark Yellow Underwing (_Cordigera_) + Small Yellow Underwing (_Tenebrata_) + Bordered Sallow (_Umbra_) + Lunar Double Stripe (_Lunaris_) + + =Geometræ.= + Brimstone (_Luteolata_) + Speckled Yellow (_Macularia_) + Purple Thorn (_Tetralunaria_) + Scalloped Hazel (_Bidentata_) + Brindled Beauty (_Hirtaria_) + Peppered (_Betularia_) + Waved Umber (_Abruptaria_) + Ringed Carpet (_Cinctaria_) + Square Spot (_Consonaria_) + Small Engrailed (_Crepuscularia_) + Engrailed (_Biundularia_) + Grey Birch (_Punctularia_) + Small Grass Emerald (_Viridata_) + All species of family _Ephyridæ_ + Cream Wave (_Remutaria_) + White Wave (_Pusaria_) + Round-winged Wave (_Rotundaria_) + Common Wave (_Exanthemata_) + Clouded Silver (_Temerata_) + White-pinion Spotted (_Bimaculata_) + Latticed Heath (_Clathrata_) + Brown Silver-line (_Petraria_) + Barred Umber (_Pulveraria_) + Netted Mountain (_Carbonaria_) + Common Heath (_Atomaria_) + Bordered White (_Piniaria_) + Rest Harrow (_Ononaria_) + Yellow Belle (_Ochrearia_) + Clouded Border (_Marginata_) + Horse Chestnut (_Hippocastanaria_) + Pretty Pinion (_Adæquata_) + Pugs (_Venosata_, _Consignata_, _Pulchellata_, _Plumbeolata_, + _Satyrata_, _Castigata_, _Pusillata_, _Irriguata_, _Indigata_, + _Nanata_, _Vulgata_, _Assimilata_, _Exiguata_, _Coronata_) + Yellow-barred Brindle (_Viretata_) + Ruddy High-flier (_Ruberata_) + May High-flier (_Trifasciata_) + Common Carpet (_Sociata_) + Silver-ground Carpet (_Montanata_) + Streamer (_Nigrofasciaria_) + Barberry Carpet (_Berberata_) + Flame Carpet (_Designata_) + Twin-spot Carpets (_Ferrugata_ and _Unidentaria_) + Scarce Tissue (_Certata_) + Water Carpet (_Suffumata_) + Small Ph[oe]nix (_Silaceata_) + Oblique-striped (_Virgata_) + Broom Tip (_Rufata_) + +A number of the Micros are also out this month. About twenty species of +the _Pyralides_, one or two of the _Pterophori_, a few _Crambi_, about +fifty of the _Tortrices_, and no less than two hundred of the _Tineæ_. +The collector will do well to search fences and tree trunks for these +moths, whenever he has the opportunity; and also to use the net freely +in wooded country, waste places, and along hedgerows, _before_ and at +dusk. + + +JUNE + +There is a marked increase in winged insect life during this month. The +early butterflies are disappearing, or perhaps have quite left us; but +new species are taking their place. The _Sphinges_ now reach their +maximum, as do also the _Bombyces_; and the other groups are almost if +not quite up to their highest total. The _Noctuæ_ and _Geometræ_ each +amount to over a hundred species. No less than a hundred and fifty +British _Tortrices_ are on the wing; the _Tineæ_ make a near approach to +three hundred, and the _Pyralides_ of the month are not far short of +numbering a hundred species. It will thus be seen that the net and pill +boxes, as well as the setting boards, are in constant demand. + +Dull days may be well occupied in beating for moths, and in the +examination of fences and the bark of trees; and on bright days, as soon +as the butterflies have settled down to rest, the same work may be +carried on till dusk. + +Micros and _Geometræ_ are out early in the evening, when they should be +taken with the net. Later on the _Noctuæ_ may be seen playing round +their favourite flowers. + +Sugar and light traps are likely to do good service during June, and +decoy females of the _Bombyces_ group may be called to your aid. + +Larvæ are also abundant during June, and those of most of the +butterflies may be taken by carefully searching their food plants. + +The following is the list of imagines for the

and so are the _Bombyces_, but the +_Noctuæ_ and _Geometræ_ are slightly on the increase. + +As regards the Micros, a good number of fresh species may be expected, +all the groups exhibiting a marked increase in the total number on the +wing with the exception of the _Tineæ_. + +Sugaring is likely to pay well this month, and many moths may be +attracted by light.

Light traps may also be used with much success during August. + +Fallen fruits should be examined for the larvæ that feed within them; +and late in the month ripe fruit will supply food to the lovers of +sweets. + +Ivy blossom should be well worked at night; and clover and lucerne +fields form admirable hunting grounds for moths at night, especially +just after rain. + +Larvæ are to be obtained in

deal to be done both with butterflies and moths. + +Many of the former are worn and ragged, but good fresh specimens of some +species may be taken. Clover and lucerne fields and the flowery borders +of corn fields remain very attractive. + +Tree trunks and palings should be searched as before. Sugar still +attracts numbers of the _Noctuæ_; and ivy blossom should be examined at +night whenever an opportunity offers itself. + +September is a good month for larva hunting. Most of the species that +pupate in the autumn are now full fed, and will undergo the change to +the chrysalis state shortly after they have been housed, thus giving but +little trouble to the entomologist. The day feeders may be beaten or +swept from their food plants, but, of course, the nocturnal species are +best discovered by searching at night. + +Some have already 'gone down' for the winter, and, consequently, pupa +hunting may be started. However, as there is yet much to be done with +imagines and larvæ, it may, perhaps, be better to leave the pupæ alone +till about the end of the month, especially as many of the larvæ have +not yet had time to complete their transformation. + +The list of imagines for September includes: + + =Butterflies.= + Clouded Yellow (_Edusa_) + Brimstone (_Rhamni_) + Queen of Spain (_Latona_) + Comma (_C-Album_) + Large Tortoiseshell (_Polychloros_) + Small Tortoiseshell (_Urticæ_) + Peacock (_Io_) + Camberwell Beauty (_Antiopa_) + Red Admiral (_Atalanta_) + Painted Lady (_Cardui_) + Speckled Wood (_Egeria_) + Wall (_Megæra_) + Grayling (_Semele_) + Large Heath (_Tithonus_) + Small Heath (_Pamphilus_) + Small Copper (_Phl[oe]as_) + Common Blue (_Icarus_) + Clifden Blue (_Bellargus_) + Chalk-hill Blue (_Corydon_) + Holly Blue (_Argiolus_) + + =Sphinges.= + Death's-head Hawk (_Atropos_) + Convolvulus Hawk (_Convolvuli_) + Humming Bird Hawk (_Stellatarum_) + + =Bombyces.= + Tortrix (_Undulanus_) + Crimson Speckled (_Pulchella_) + Vapourer (_Antiqua_) + Pale Oak Eggar (_Cratægi_) + Lesser Lutestring (_Diluta_) + + =Noctuæ.= + Figure of Eight (_Cæruleocephala_) + Small Wainscot (_Fulva_) + Bullrush (_Arundinis_) + Large Wainscot (_Lutosa_) + Frosted Orange (_Ochracea_) + Rosy Rustic (_Micacea_) + Feathered Brindle (_Australis_) + Beautiful Gothic (_Hispidus_) + Antler (_Graminis_) + Flounced Rustic (_Testacea_) + Hedge Rustic (_Cespitis_) + Haworth's Minor (_Haworthii_) + Anomalous (_Anomala_) + Shuttle-shaped Dart (_Puta_) + Dark Sword Grass (_Suffusa_) + Pearly Underwing (_Saucia_) + Turnip (_Segetum_) + Heart and Dart (_Exclamationis_) + Autumn Rustic (_Glareosa_) + Mouse (_Tragopogonis_) + Red-lined Quaker (_Lota_) + Yellow-lined Quaker (_Macilenta_) + Genus _Anchocelis_ + Genus _Xanthia_ + Centre-barred Sallow (_Xerampelina_) + Double Kidney (_Retusa_) + Genus _Polia_ + Black Rustic (_Nigra_) + Green-brindled Crescent (_Oxyacanthæ_) + Marvel-du-jour (_Aprilina_) + Angle Shades (_Meticulosa_) + Flame Brocade (_Flammea_) + Brindled Green (_Protea_) + Genus _Calocampa_ + Genus _Xylina_ + Herald (_Libatrix_) + Gold Spot (_Festucæ_) + Silver Y (_Gamma_) + Scarce Bordered Straw (_Armigera_) + Clifden Nonpareil (_Fraxini_) + Buttoned Snout (_Rostralis_) + + =Geometræ.= + Bordered Beauty (_Apiciaria_) + Brimstone (_Luteolata_) + Genus _Eugonia_ + November (_Dilutata_) + Autumnal (_Filigrammaria_) + Juniper Pug (_Sobrinata_) + Shaded Broad Bar (_Variata_) + Slender-striped Rufous (_Lapidata_) + Tissue (_Dubitata_) + Carpets (_Siderata_, _Miata_, _Immanata_) + Chevron (_Testata_) + Mallow (_Cervinata_) + Streak (_Spartiata_) + + +OCTOBER + +As there is very little winged life this month, and the larvæ have +nearly all sought out their winter quarters, special attention may be +given to pupæ. The earlier this work is started after the insects have +completed their change the better. If left late, many pupæ will have +been destroyed by floods, moles, &c., and a prolonged series of frosty +days may render digging unproductive if not impossible. Again, it must +be remembered that some larvæ are not yet down, and by digging at the +roots of the trees on which they are feeding, you are preparing an +acceptable bed for the late species, for the pupæ of which you may call +again in about a month. + +Larvæ may be obtained by beating and searching as before, but this work +should be done as early in the month as possible, since but few are +feeding after the first week or so. + +Butterfly catching is now practically over, only a few of the late +species and the hybernators being on the wing, and these only on mild +days. + +_Noctuæ_ are still attracted by sugar and ivy blossom, and a few may be +found at rest. _Geometræ_ and Micros may be taken from palings and tree +trunks by day, or caught flying at dusk. + +The imagines of October may include the following butterflies: + + Brimstone (_Rhamni_) + Pale Clouded Yellow (_Hyale_) + Clouded Yellow (_Edusa_) + Comma (_C-Album_) + Large Tortoiseshell (_Polychloros_) + Small Tortoiseshell (_Urticæ_) + Peacock (_Io_) + Camberwell Beauty (_Antiopa_) + Red Admiral (_Atalanta_) + Painted Lady (_Cardui_) + Small Copper (_Phl[oe]as_) + +And a few late 'Blues.' + +The principal moths of the month are: + + =Sphinges.= + Death's-head Hawk (_Atropos_) + + =Bombyces.= + Plumed Prominent (_Plumigera_) + + =Noctuæ.= + Large Wainscot (_Lutosa_) + Red-lined Quaker (_Lota_) + Yellow-lined Quaker (_Macilenta_) + Beaded Chestnut (_Pistacina_) + Brown-spot Pinion (_Litura_) + Chestnut (_Vaccinii_) + Dark Chestnut (_Spadicea_) + Red-headed Chestnut (_Erythrocephala_) + Satellite (_Satellitia_) + Dotted Chestnut (_Rubiginea_) + Orange Upperwing (_Croceago_) + Brick (_Circellaris_) + Brindled Ochre (_Templi_) + Green Brindled Crescent (_Oxyacanthæ_) + Marvel-du-jour (_Aprilina_) + Angle Shades (_Meticulosa_) + Flame Brocade (_Flammea_) + Red Sword-grass (_Vetusta_) + Sword-grass (_Exolita_) + Genus _Xylina_ + Sprawler (_Sphinx_) + Silver Y (_Gamma_) + + =Geometræ.= + Feathered Thorn (_Pennaria_) + Vestal (_Sacraria_) + Scarce Umber (_Aurantiaria_) + Mottled Umber (_Defoliaria_) + Winter (_Brumata_) + Northern Winter (_Boreata_) + November (_Dilutata_) + Juniper Carpet (_Juniperata_) + Gem (_Fluviata_) + Carpets (_Siderata_, _Miata_) + Mallow (_Cervinata_) + Streak (_Spartiata_) + + +NOVEMBER + +No butterflies are to be seen this month with the exception of the +hybernating species, and even these will not venture on the wing unless +the weather is mild and bright for the season. + +Most of the moths met with are also hybernators, but a few species are +to be found only at this season, and these should be looked for on +fences and tree trunks. A few _Noctuæ_ may be taken at sugar, and the +_Geometræ_ attracted by lights. + +The only larvæ now existing are hybernators, and many of these may be +met with during your pupa-digging operations; but they are best left +alone till the spring, as a rule. + +The chief work of the entomologist in November is certainly pupa +hunting, and this may be carried on in real earnest whenever the weather +is favourable, following the instructions given in Chapter VII. + +It will be remembered, also, that many of the _Lepidoptera_ pass the +winter in the egg state, and search may be made for ova when time +permits. + +The November list, besides some of the hybernating species previously +mentioned, include: + + =Bombyces.= + December (_Populi_) + + =Noctuæ.= + Genus _Cerastis_ + Satellite (_Satellitia_) + Dotted Chestnut (_Rubiginea_) + Orange Upperwing (_Croceago_) + Brindled Ochre (_Exempli_) + + =Geometræ.= + Feathered Thorn (_Pennaria_) + Scarce Umber (_Aurantiaria_) + Mottled Umber (_Defoliaria_) + Winter (_Brumata_) + Northern Winter (_Boreata_) + + +DECEMBER + +Outdoor work is now at a minimum. The weather is too severe, as a rule, +to allow pupa digging to be carried on with either success or comfort, +but favourable opportunities should be seized for this employment as +well as for ova collecting. + +Now and again we may meet with _P. Populi_ at rest by day, or fluttering +round a light at night. _Brumata_ and _Defoliaria_ may also be seen, and +the Early Moth (_Rupicapraria_) may appear on the wing before the new +year; but nothing is likely to be met with beyond these save the +hybernators, already named in other lists, and some of the _Tineæ_. + +It is a good plan to utilise your spare time during the dreary months of +winter by attending to your cabinet. Rearrange your specimens where +necessary, and see that all are properly labelled; remove all greasy +specimens, and deal with them as recommended on page 127; also renew the +supply of camphor or naphthaline in your drawers and store boxes. Time +may also be found for the construction of apparatus that is likely to be +required next season, and for repairing any that has been damaged during +the work of the last. + + + + +COLOURED PLATES + + +PLATE I (_Frontispiece_) + + 1.

Information about the Mission of Project Gutenberg-tm + +Project Gutenberg-tm is synonymous with the free distribution of +electronic works in formats readable by the widest variety of computers +including obsolete, old, middle-aged and new computers. It exists +because of the efforts of hundreds of volunteers and donations from +people in all walks of life. + +Volunteers and financial support to provide volunteers with the +assistance they need are critical to reaching Project Gutenberg-tm's +goals and ensuring that the Project Gutenberg-tm collection will +remain freely available for generations to come. In 2001, the Project +Gutenberg Literary Archive Foundation was created to provide a secure +and permanent future for Project Gutenberg-tm and future generations. +To learn more about the Project Gutenberg Literary Archive Foundation +and how your efforts and donations can help, see Sections 3 and 4 +and the Foundation web page at http://www.gutenberg.org/fundraising/pglaf. + + +Section 3. Information about the Project Gutenberg Literary Archive +Foundation + +The Project Gutenberg Literary Archive Foundation is a non profit +501(c)(3) educational corporation organized under the laws of the +state of Mississippi and granted tax exempt status by the Internal +Revenue Service. The Foundation's EIN or federal tax identification +number is 64-6221541. Contributions to the Project Gutenberg +Literary Archive Foundation are tax deductible to the full extent +permitted by U.S. federal laws and your state's laws. + +The Foundation's principal office is located at 4557 Melan Dr. S. +Fairbanks, AK, 99712., but its volunteers and employees are scattered +throughout numerous locations.

Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://www.gutenberg.org/fundraising/donate + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses. Donations are accepted in a number of other +ways including checks, online payments and credit card donations. +To donate, please visit: +http://www.gutenberg.org/fundraising/donate + + +Section 5. General Information About Project Gutenberg-tm electronic +works. + +Professor Michael S. Hart is the originator of the Project Gutenberg-tm +concept of a library of electronic works that could be freely shared +with anyone. For thirty years, he produced and distributed Project +Gutenberg-tm eBooks with only a loose network of volunteer support. + +Project Gutenberg-tm eBooks are often created from several printed +editions, all of which are confirmed as Public Domain in the U.S. +unless a copyright notice is included. Thus, we do not necessarily +keep eBooks in compliance with any particular paper edition. + +Most people start at our Web site which has the main PG search facility: + + http://www.gutenberg.org + +This Web site includes information about Project Gutenberg-tm, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. + diff --git a/34131-8.zip b/34131-8.zip Binary files differnew file mode 100644 index 0000000..c151795 --- /dev/null +++ b/34131-8.zip diff --git a/34131-h.zip b/34131-h.zip Binary files differnew file mode 100644 index 0000000..46f2abe --- /dev/null +++ b/34131-h.zip diff --git a/34131-h/34131-h.htm b/34131-h/34131-h.htm new file mode 100644 index 0000000..5b51e7a --- /dev/null +++ b/34131-h/34131-h.htm @@ -0,0 +1,20761 @@ +<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" + "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> +<html xmlns="http://www.w3.org/1999/xhtml"> +<head> +<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> +<title>The Project Gutenberg eBook of Butterflies and Moths, by William S.

The number of British Butterflies, however, is +so limited that a place has been found for a figure and a description +of every species; and, of the larger moths, many +of the common and typical kinds have been included. An +introduction to the study of the Micro-lepidoptera has also +been added.</p> + +<p>No trouble has been spared to render this work thoroughly +practical. In addition to the verbal descriptions of so many +species, twelve coloured plates and a large number of woodcuts +have been specially prepared to help the student in his +work. It is believed that the extreme care with which these +have been produced will render them of the greatest assistance +to the collector in the recognition of his specimens.</p> + +<p>But he has not only to recognise his specimens—he must +first catch them; and here full directions have been given to +insure success in this part of his work, as well as in the +management, preservation, and arrangement of his captures.</p> + +<p>The Author hopes that this volume may be the means of +adding many happy hours—hours of the purest enjoyment—to +the lives of those whom he has succeeded in luring into +the fields and lanes and woods of the Out-door World.</p> +<p><!-- Page vii --><span class="pagenum"><a name="Page_vii" id="Page_vii">[Pg vii]</a></span></p> + + +<h2>CONTENTS</h2> + + +

+<p>The word <i>Lepidoptera</i>, which you see at the head of this page, is +the name of the order of insects to which this volume is to be +devoted. It is formed from two Greek words, one (<i>lepis</i>) signifying +a <i>scale</i>, and the other (<i>pteron</i>) denoting a <i>wing</i>; and was +applied by the great naturalist Linnæus to the scaly-winged insects +popularly known as Butterflies +and Moths.</p> + +<div class="figright" style="width: 400px;"> +<a name="FIG_1" id="FIG_1"></a><img src="images/i_018.jpg" width="400" height="222" alt="" title="" /> +<span class="caption">Fig. 1.—Scales from the Wings of +Butterflies.</span> +</div> + +<p>Every one of my readers +has undoubtedly handled some +of the interesting creatures of +this group—having been led +to do so either by the extreme +beauty of their clothing, or, +perhaps, from a murderous +intent in order to protect his +own garments from the ravages +of a supposed marauder. A light mealy powder will probably have +been observed afterwards on the fingers that have touched the +victim's wings.</p> + +<p>This powder, although it sometimes presents a beautiful glossy +surface when spread over the skin, does not exhibit any definite +form or structure without a more minute examination. Yet these<!-- Page 2 --><span class="pagenum"><a name="Page_2" id="Page_2">[Pg 2]</a></span> +are the scales that led the immortal naturalist to invent the somewhat +long but useful term <i>Lepidoptera</i>.</p> + +<p>The very next time the opportunity offers itself, dust off a little +of the mealy powder with a small and very soft brush on to a +strip of white paper or a slip of glass, and examine it with a +powerful lens or the low power of a compound microscope. What +a sight you will then behold! Each little particle of dust is a +beautifully formed scale, stamped with a number of minute +rounded projections, and often displaying the most gorgeous colours. +A great variety of designs and tints are often exhibited by the +'dust' from a single wing. Take, for instance, for your inspection, +scales from the wing of one of our commonest insects, the Small +Tortoiseshell Butterfly (<a href="#Plate_III">Plate +III</a>), and you will be surprised +at the pleasing contrasts. But +when your curiosity leads you +to deal with others in the same +manner, the varied display of +forms and colours is simply +amazing.</p> + +<div class="figleft" style="width: 352px;"> +<a name="FIG_2" id="FIG_2"></a><img src="images/i_019.jpg" width="352" height="351" alt="" title="" /> +<span class="caption">Fig. 2.—Portion of the Wing of a +Butterfly from which some of +the scales have been removed.</span> +</div> + +<p>In order that we may learn +still more of the structure of +the wings of the <i>Lepidoptera</i>, +we will examine a portion of +one from which some of the +scales have been removed, +again bringing the lens or the +microscope into our service. +We now see that the scales +are arranged in rows with great regularity on a thin and transparent +membrane, which is supported by a system of branching +rays. And the membrane itself, in parts which have been laid +bare, is marked with regular rows of dots—the points at which +the scales were originally attached by means of short hollow +rods.</p> + +<p>The framework that supports the thin membrane we have +spoken of as consisting of a system of <i>rays</i>, but to these the terms +<i>veins</i>, <i>nerves</i>, <i>nervures</i>, or <i>nervules</i> are more commonly applied by +various naturalists. We cannot do better, however, than adhere +to the name originally used, for the structures in question do not +perform the functions of veins, though at first they contain blood,<!-- Page 3 --><span class="pagenum"><a name="Page_3" id="Page_3">[Pg 3]</a></span> +nor are they themselves parts of the nervous systems of the insects +to which they belong.</p> + +<p>The result of our examination of the wings of butterflies and +moths has been to justify the application of the term <i>Lepidoptera</i>; +but we must now study other equally important and interesting +features of the structure of these insects. First, let us note the +general form of the body.</p> + +<div class="figright" style="width: 159px;"> +<a name="FIG_3" id="FIG_3"></a><a href="images/i_020.jpg"><img src="images/i_020_tn.jpg" width="159" height="400" alt="" title="Linked to larger image of Figure 3." /></a> +<span class="caption">Fig. 3.—Body of a Butterfly—Under +Side. +</span> +<p>1-7, segments of the abdomen; +8, anal extremity; <i>a</i>, antennæ; +<i>b</i>, tarsus; <i>c</i>, tibia; <i>d</i>, femur; +<i>e</i>, palpi; <i>f</i>, head; <i>g</i>, thorax.</p> +</div> + + + +<p>A cursory glance at this portion of the +creature's anatomy will show that it consists +of three distinct and well-defined +parts. In front there is the head, the size +of which is somewhat small in proportion. +Two very large eyes make up the greater +portion of its bulk. It is remarkable, too, +that butterflies possess eyes proportionately +much larger than those of moths. +Now, since butterflies always fly by day, +and moths are, generally speaking, nocturnal +insects, we might be led to suppose +that the reverse of this arrangement would +have suited the creatures better; for a +small eye, we should think, would be able +to collect sufficient light in the daytime +to form a bright image, and a larger light-receiving +area would be necessary during +the darker hours for the same purpose. +But it is evident that the sense of vision +must depend on other conditions besides +the size of the eye; and as these conditions +are not understood in relation to the +eyes of insects, any attempt at an explanation +would be quite useless.</p> + +<p>The eye of a butterfly or moth is worthy +of a closer examination, for it is a most beautiful and marvellous +structure. The outer globular transparent membrane—the <i>cornea</i>—is +divided into a large number of minute polygonal <i>facets</i>, each +one of which admits light into a small conical compartment surrounded +by a coloured membrane, and supplied with a fibre of the +nerve of vision (the <i>optic</i> nerve). Hence the eye is often spoken of +as <i>compound</i>.</p> + +<p>If you look closely into the eyes of various butterflies and moths<!-- Page 4 --><span class="pagenum"><a name="Page_4" id="Page_4">[Pg 4]</a></span> +you will generally see a ground colour of grey, blue, brown, or +black; but when viewed at certain angles in a strong light the +most gorgeous hues of metallic brilliancy—gold, copper, and bronze—are +to be observed.

Thus each little division of a compound eye forms its +own image of the object that happens to be exactly opposite its +facet. But how many facets do we find in a single eye? Sometimes +only a few hundreds, but sometimes +as many as seventeen or eighteen +thousand! We must not, however, +conclude that the nature of the vision +of butterflies and moths is necessarily +very different from our own. We have +two eyes, but the images formed by them +are both blended, so that we do not see +double. We can understand, therefore, +that the thousands of images formed in +a single eye may be blended together so +as to form one continuous picture. Still +there remains this difference: while in our own case the two images +formed by the two eyes are practically the same, in the case of +insects every one of the little conical tubes of a compound eye +forms an image of an object that cannot possibly be formed by any +one of the others. Thus, if the lepidopterous insect sees a continuous +picture of its surroundings, such a picture is produced by the overlapping +and blending, at their edges, of hundreds or thousands of +distinct parts.</p> + +<p>There is yet another interesting difference between the vision +of these insects and that of ourselves. As already stated, our two +eyes are both turned toward the same point at the same time. +But look at the butterfly's eyes. Here are no movable eyeballs, +and the two eyes, placed as they are at the <i>sides</i> of the head, are +always turned in <i>opposite</i> directions. The corneæ, too, are very +convex; and consequently the range of vision is vastly wider than<!-- Page 5 --><span class="pagenum"><a name="Page_5" id="Page_5">[Pg 5]</a></span> +ours. A boy is often easily surprised by a playmate who approaches +him stealthily from behind, but did you ever try the same game +with a butterfly? I have, many a time. After getting cautiously +so near to a butterfly at rest as to be able to distinguish between +its head and its hinder extremity, I have quietly circled round it so +as to approach it from behind, being at the time under the impression +that it wouldn't see me under those circumstances. But not +the slightest advantage did I derive from this stratagem, for the +position and construction of its eyes enabled it to see almost all +ways at once.</p> + +<p>In addition to the two compound eyes, the <i>Lepidoptera</i>, or at +least most of them, are provided with two small simple eyes; +but these are generally so hidden among the closely set hair that +covers the head, that it is doubtful whether they are of much +service as organs of vision.</p> + +<div class="figleft" style="width: 235px;"> +<a name="FIG_5" id="FIG_5"></a><img src="images/i_022a.jpg" width="207" height="400" alt="" title="" /> +<span class="caption">Fig. 5.—Antennæ of +Butterflies.</span> +</div> + +<div class="figright" style="width: 235px;"> +<a name="FIG_6" id="FIG_6"></a><img src="images/i_022b.jpg" width="235" height="400" alt="" title="" /> +<span class="caption">Fig. 6.—Antennæ of +Moths.</span> +</div> + +<p>The antennæ proceed from two points close to the upper +borders of the eyes.

In moths the antennæ are sometimes long, slender, +and pointed. Some are thick, and more or less prismatic in form; +while others are slightly or deeply pectinated or comb-like. The<!-- Page 6 --><span class="pagenum"><a name="Page_6" id="Page_6">[Pg 6]</a></span> +antennæ of butterflies are always straight, or only slightly curved; +and, although the insects can sway them bodily, they have no +power to bend them, or to stow them away in any place of shelter. +Moths, on the other hand, when at rest, are almost invariably found +to have their antennæ snugly tucked under the wings, and brought +so closely against the side of the head for this purpose that even +the uncovered portion is often difficult to find.</p> + +<p>There are two other prominent appendages belonging to the +heads of the <i>Lepidoptera</i>. These are the <i>labial palpi</i> or feelers of +the lips.

This instrument is so long and +slender that it seems almost impossible that it can be a tube +through which a liquid freely passes. But a careful examination +will show that this is the case. It is composed of two separate +pieces—two half tubes, which, when closely applied to each other, +form a very thin and flexible pipe, perfectly air-tight and adapted +for suction. Sometimes you can see a butterfly or moth manipulating +with its proboscis as if it required readjustment in some way +or other. It has split the tube throughout its length, so that it now +looks like two exceedingly fine hairs. Then, after a short time, the +two halves are put together again, and immediately, as if by magic, +become a single tube in which no kind of seam is to be observed +without a powerful magnifier.</p> + +<p>In order to observe the nature of such a wonderful arrangement +we must have recourse to the aid of a good microscope. Thus +assisted, we can see at once how the junction of the two sides of +the proboscis is brought about so quickly and so perfectly. The +inner edges of each half are very regularly fringed with lines of +closely set hairs—so regular, in fact, are they, that they give one +the idea of long yet minute beautifully formed combs. When the +two parts are brought together, the hairs of two opposite edges +interlock, those on one side exactly filling the spaces between those +of the other.</p> + +<p>The microscope also reveals another interesting fact, viz. that<!-- Page 7 --><span class="pagenum"><a name="Page_7" id="Page_7">[Pg 7]</a></span> +the proboscis is not a single tube, but, although so remarkably thin, +is really a set of three distinct pipes, one lying on each side of the +central one. It is said that the central tube only is used for sucking +up the liquid food, and there seems to be some doubt as to the +uses of the other two. Some naturalists are of opinion that the +latter are air tubes, and are connected with the respiration of the +insect; while others say that through these the insects eject a thin +watery fluid with which to dissolve or dilute those sweetmeats +that are not sufficiently liquid to be readily sucked up. But possibly +both these opinions are correct, the proboscis serving all three +of the purposes here named. The only observation of my own +bearing on the subject is this. While a moth was feeding on a +drop of syrup in a strong light, a powerful lens revealed drops, +of liquid, mingled with bubbles of air, passing +alternately <i>up and down</i> the two lateral tubes of +the proboscis. At the same time the upward +current of syrup in the central tube was by no +means steady and continuous.</p> + +<p>When this organ is not in use, it is beautifully +coiled into a close spiral which lies between the +labial palpi. The length varies considerably in +different insects, and consequently the number of +turns in the spiral must differ also. Sometimes +there are less than two turns, while some of the +longer ones form spirals of from six to ten turns.</p> + +<p>In concluding our brief account of the head +of lepidopterous insects it is, I suppose, hardly +necessary to add that there is no kind of chewing +apparatus to be described; all the members of this order, at least in +the perfect state, deriving the whole of the little nourishment they +require entirely by suction through the proboscis or 'trunk.'</p> + +<p>The second division of the body is the <i>thorax</i>.

But when we are a little farther advanced in our<!-- Page 8 --><span class="pagenum"><a name="Page_8" id="Page_8">[Pg 8]</a></span> +insect studies, we shall have to become acquainted with detailed +descriptions given as aids to the identification of species. Now, +such descriptions cannot be satisfactory, either to the one who +gives or to him who receives, unless expressed in such definite +terms as render a misunderstanding impossible. A botanist cannot +give an accurate and concise description of a flower without the use +of certain names and expressions which have gradually become an +almost necessary part of his vocabulary; neither can an entomologist +give a really useful, and, at the same time, a <i>succinct</i> +description of an insect unless he is acquainted with the names of its +parts. Therefore, seeing that we distinguish the various species of +butterflies and moths <i>mainly</i> by the arrangement and colour of the +markings of their wings, it is really necessary that we should know +the names of the different parts of these organs. For this reason I +have inserted drawings of a fore and of a hind wing of a butterfly, +together with the names of the various parts of the wings, and also +the names of the principal rays or <i>nervures</i>. Yet I would not +advise any young entomologist to attempt to commit to memory +all the names given. Rather use the diagram for reference when +occasion requires, more particularly when you have an insect in +your possession that you desire to study. In ordinary descriptions +of butterflies and moths the names of the <i>nervures</i> are not so +generally used as those of the <i>parts</i> of the wing. Consequently it +is exceedingly useful to know what is meant by the terms <i>base</i>, +<i>costal margin</i>, <i>apex</i>, <i>hind margin</i>, <i>anal angle</i>, <i>inner margin</i>, +<i>discoidal cell</i> &c. as applied to the wing.</p> + +<p>The two pairs of wings are attached to the second and third +segments of the thorax; but of the <i>three</i> pairs of legs, which we +have next to consider, one pair arises from each of the three +segments. The arrangement of these limbs is well shown in the +sketch on page 3, as are also the names of the different parts of +the limb, the latter being given for reference by the reader when +the need arises.</p> + +<p>All insects, in their perfect state, we are told, have three pairs +of legs; but if you examine the under surface of certain butterflies, +such as the Marbled White, or any of the Vanessas, Browns, or +Heaths, it is quite likely that you will raise objection to such a +statement; for in these you may possibly see only four legs. But this +is the result of a too cursory observation. Look a little more closely +at your specimen, and you will see a pair of smaller legs folded +up under the fore part of the thorax. By means of a blunt needle<!-- Page 9 --><span class="pagenum"><a name="Page_9" id="Page_9">[Pg 9]</a></span> +you can straighten out these limbs, and then the difference in +length to be observed between them and the other four is very +striking indeed.

On one<!-- Page 10 --><span class="pagenum"><a name="Page_10" id="Page_10">[Pg 10]</a></span> +occasion, however, while watching a Peacock Butterfly apparently +engaged in cleaning its divided proboscis, I observed that this organ +was frequently passed under the thorax, and that the front pair of +legs were pressed against it on each side, while it was being drawn +outward between them. It is probable, therefore, that these limbs +constitute a pair of brushes by means of which the fine grooves of +the divided trunk are cleared of any solid or sticky matter that may +lodge therein. It is certain that moths, and those butterflies that +possess six <i>equal</i> legs, use the front pair for this same purpose. The +former, also, employ them for brushing their antennæ, which seem +to be, by the way, particularly sensitive to different kinds of +irritation.</p> + +<p>It is a well-known fact that tobacco smoke has a powerful +influence on certain small insects; and even though it can hardly +be regarded as a perfect all-round insecticide, it is certainly more +or less objectionable to the larger and hardier species. A short time +since, while watching a number of newly +emerged moths of the <i>Sphinx</i> group, and at +the same time enjoying the solace afforded by +the luxurious weed, a puff of the smoke was +accidentally allowed to play into the box in +which my pets were for the time imprisoned. +Immediately they rubbed their front legs +vigorously over the antennæ, as if to remove +the obnoxious irritant that had thus intruded on their presence. +Similar observations have led many naturalists to suppose that the +antennæ are the seat of various senses, such as those of touch, +hearing, and smell. Seeing that insects do not, as far as we know, +possess special organs for all the five senses which we enjoy (and it +is interesting to note here that some insects certainly experience +other sensations which are quite beyond our ken), we can quite +understand the common tendency to locate the seats of certain of +the senses in such easily affected parts as the antennæ. But little, +I believe, has been definitely proved save that the antennæ are +sensitive to touch and to irritants generally.</p> + +<p>While speaking of the senses of insects, I cannot refrain from +mentioning a most remarkable example of a peculiar sensitiveness +that has been observed in certain moths of the family <i>Bombyces</i> +(<a href="#Page_217">page 217</a>)—notably the Oak Eggar, the Emperor, and the Kentish +Glory. Take a newly emerged female of either of these species, +shut her up in a small box, conceal the box in your pocket, and then<!-- Page 11 --><span class="pagenum"><a name="Page_11" id="Page_11">[Pg 11]</a></span> +walk about in some country spot known to you as being one of +the haunts of that species of moth. Then, if any of the males of +the same species happen to be in the neighbourhood, they will +settle or hover about close to the female which, although still +concealed and quite out of their reach, has attracted them to the +spot.</p> + +<p>What a marvellously acute sense this must be, that thus enables +the insects to scent out, as it were, their mates at considerable +distances, even when doubly surrounded by a wooden box and the +material of a coat pocket! You would naturally expect that +entomologists have turned this wonderful power to account. Many +a box has been filled with the beautiful Kentish Glories of the male +kind, who had been led into the snare by the attractions of a virgin +Glory that they were never to behold. Many an Emperor has also +been decoyed from his throne to the place of his execution, beguiled +by the imaginary charms of an Empress on whom he was never to +cast one passing glance. And these and other similar captures +have been made in places where, without the employment of the +innocent enchantress, perhaps not a single male could have been +found, even after the most diligent search.</p> + +<p>Speaking of this surprising sense, I am again tempted to revert +to the antennæ; for it is a remarkable fact that the males of those +species of moths which exhibit the power of thus searching out their +mates, are just those that are also remarkable for their very broad +and deeply pectinated antennæ—a fact that has led to the supposition +that the power in question is located in the antennæ, and is +also proportional to the amount of surface displayed by these organs.</p> + +<p>Up to the present time we have been considering the butterfly +and moth in their perfect forms, but everybody knows that +the former is not <i>always</i> a butterfly, nor is the latter always a +moth; but that they both pass through certain preparatory stages +before they attain their final winged state.</p> + +<p>We shall now notice briefly what these earlier stages are, leaving +the detailed descriptions of each for the following chapters.</p> + +<p>The life of the perfect butterfly or moth is of very short +duration, often only a few days, nearly the whole of its existence +having been spent in preparing itself for the brief term to be enjoyed</p> + +<p class="poem"> +<span class="i4">... in fields of light,</span><br /> +And where the flowers of Paradise unfold. +</p> + +<p>It may be interesting to consider of what use the metamorphoses<!-- Page 12 --><span class="pagenum"><a name="Page_12" id="Page_12">[Pg 12]</a></span> +of insects are, and to what extent these metamorphoses render them +fit for the work they have to do.</p> + +<p>It is certain that the chief work of insects, taken as a whole, is +to remove from the earth the excess of animal and vegetable matter. +If they are to do this work effectually, it is clear that they must +be very voracious feeders, and also be capable of multiplying their +species prodigiously. Now each of these powers requires the special +development of a certain set of organs, and an abnormal development +of one set must necessarily be produced at the expense of the +other. Hence we find insects existing in two distinct stages, with +or without an intermediate quiescent state, during the first of which +the digestive apparatus is enormously developed, while the reproductive +organs occupy but very little space; then, during the other +stage, the digestive apparatus is of the simplest possible description, +and the organs of reproduction are in a perfect state of +development.</p> + +<p>Allowing, then, that the chief work of the insect is the removal +of surplus organic matter, we can see that a large share of its life +should be spent in the larval or grub stage, and that the perfect +state <i>need</i> not occupy any more time than is necessary for the +fertilisation of the eggs that almost completely fill the body of the +female at the time of her emergence from the chrysalis shell.</p> + +<p>Many insects undergo their metamorphoses by slow degrees, +but the <i>Lepidoptera</i>, after existing for some considerable period +without any important visible change in structure, pass by a rapid +transition into the next state. Thus, a caterpillar, that has not +altered in general form for several weeks, changes into a chrysalis +within the course of a few days; and again, after a period of quiescence +that may extend throughout the whole of the colder months, +becomes a perfect butterfly or moth within twenty minutes of the +moment of its emergence.</p> + +<p>But this suddenness is more apparent than real, as may easily be +proved by internal examinations of the insect at various stages of +growth; showing that we are led astray by the rapidity of <i>external</i> +changes—the mere <i>moultings</i> or castings of the skin—while the +gradual transformations proceeding within are not so readily +observed.</p> + +<p>We have already said that the life of the perfect butterfly or +moth is short. A few days after emergence from the chrysalis case, +the female deposits her eggs on the leaves or stems of the plant +that is to sustain the larvæ. Her work is now accomplished, and<!-- Page 13 --><span class="pagenum"><a name="Page_13" id="Page_13">[Pg 13]</a></span> +the few days more allowed her are spent in frolicking among the +flowers, and sucking the sweet juices they provide. But males +and females alike—bedecked with the most gorgeous colours and +overflowing with sportive mirth when first they take to the wing—soon +show the symptoms of a fast approaching end. Their colours +begin to fade, and the beauty-making scales of the wings gradually +disappear through friction against the petals of hundreds of flowers +visited and the merry dances with scores and scores of playful +companions. At last, one bright afternoon, while the sun is still +high in the heavens, a butterfly, more weary than usual, with heavy +and laborious flight, seeks a place of rest for the approaching +night. Here, on a waving stalk, it is soon lulled to sleep by a gentle +breeze.</p> + +<p>Next morning, a few hours before noon, the blazing sun calls +it out for its usual frolics. But its body now seems too heavy to +be supported by the feeble and ragged wings, and, after one or two +weak attempts at play, incited by the approach of a younger and +merrier companion, it settles down in its final resting place. On +the following morning a dead butterfly is seen, still clinging by its +claws to a swinging stem, from which it is eventually thrown during +a storm.</p> + +<p>The tale of the perfect moth is very similar to the above, except +that it is generally summoned to activity by the approach of +darkness.</p> + +<p>We see, then, that butterflies and moths exhibit none of that +quality which we term parental affection. Their duty ends with +the deposition of the eggs, and the parents are dead before the +young larvæ have penetrated the shell that surrounds them.</p> + +<p>Yet it is wonderful to see how unmistakably the females +generally lay their eggs on the very plants that provide the +necessary food for their progeny, as if they were not only conscious +of and careful concerning the exact requirements of their offspring, +but also possessed such a knowledge of botanical science as +enabled them to discriminate between the plant required and all +others.</p> + +<p>Has the perfect insect any selfish motive in this apparently +careful selection of a plant on which to lay its eggs? Does the +female herself derive any benefit from the particular plant chosen +for this purpose? In most cases, certainly not. For it often +happens that the blossom of this plant is not by any means one of +those that supply the sweets which insects love, and still more<!-- Page 14 --><span class="pagenum"><a name="Page_14" id="Page_14">[Pg 14]</a></span> +frequently does it occur that the eggs are deposited either before +the flowers have appeared or after they have faded.</p> + +<div class="figleft" style="width: 226px;"> +<a name="FIG_10" id="FIG_10"></a><a href="images/i_031.jpg"><img src="images/i_031_tn.jpg" width="226" height="400" alt="" title="Linked to larger image of figure 10." /></a> +<span class="caption">Fig. 10.—The Four Stages of the +Large White Butterfly (Pieris +Brassicæ).</span> +<p><i>a</i>, larva; <i>b</i>, pupa; <i>c</i>, imago; <i>d</i>, egg.</p> +</div> + +<p>Neither can we easily impute to the insect an acquired knowledge +of the nature and wants of her offspring, or an acquaintance +with botany sufficient to enable her to distinguish plant +forms.

It is composed of a <i>calcareous</i> or limy +substance, known chemically as <i>carbonate of lime</i>. If you put +some pieces of it into an egg cup, and throw over them a little +vinegar or any other liquid acid, you will see them gradually +dissolve away, and small bubbles of carbonic acid gas will rise into +the air. Then again, if you take a long and narrow strip of the +shell, and hold one end of it in a gas or lamp flame, after a short +time that end will become softer, and will glow brightly in the +flame, for it is converted into lime—the same substance that is +used by the builders for making their mortar—and the bright glow +is really a miniature <i>lime light</i>, such as is always produced when a +piece of lime is made intensely hot.</p> + +<p>Just inside this shell you have seen a thin membrane or skin +that is easily peeled off the substance of the egg itself.

Turn over some leaves and examine their +under surfaces, choosing especially those plants which show, by +their partially eaten leaves, that they are favourites with the insect +world. Or you may amuse yourself by catching a number of butterflies—common +'Whites' are as good for the purpose as any—and +temporarily confine them in a wooden or cardboard box, containing +a number of leaves from various plants, and covered with gauze. +In this way you are sure to obtain a few females that have not yet +laid all their eggs; and if you watch your prisoners you will soon +see them carefully depositing the eggs on the under surfaces of +leaves, bending their abdomens round the edges if there is not sufficient +room to get themselves completely under. And then, when +you are satisfied with the number of eggs thus obtained for your +examination, you can have the pleasure of seeing all your liberated +captives flying joyfully in the free air.</p> + +<p>In giving these simple instructions I have assumed that the +reader has not yet learnt any of the characters by which female +butterflies are to be distinguished from their lords and masters; but +I hope that he will know soon, at least with regard to a good many +species, from which individuals he may most reasonably expect to +obtain eggs, and so be able to avoid the imprisonment, even though +only temporary, of insects which cannot satisfy his wants.</p> + +<p>Again, it is not necessary, after all, that butterflies should be +captured for the purpose of obtaining eggs. Watch them as they +hover about among your flowers. Some, you will observe, are intent +on nothing but idle frolicking; and you may conclude at once that +<i>these</i> have no immediate duty to perform. Others are flying without +hesitation from flower to flower, gorging themselves with the +sweets of life: these are not the objects of your search. But you +will descry certain others, flying round about the beds and borders +with a steadier and more matronly air, taking little or no notice of +their more frivolous companions, and paying not the slightest heed +to the bright nectar-producing cups of the numerous flowers. These<!-- Page 18 --><span class="pagenum"><a name="Page_18" id="Page_18">[Pg 18]</a></span> +are seriously engaged with family affairs only. Watch one of them +carefully, and as soon as she has settled herself on a leaf, walk steadily +towards her till you are near enough to observe her movements. +She will not move unless you approach too closely, for, like busy +folk generally, she has no time to worry about petty annoyances. +You will now actually witness the deposition of the eggs exactly as +carried on in the perfect freedom of nature; and the eggs themselves +may be taken either for examination or for the rearing of the +caterpillars.</p> + +<p>Some species of <i>Lepidoptera</i> lay some hundreds of eggs, and it +is seldom that the number laid by one female is much below a +hundred.</p> + +<p>As already stated, the under surfaces of leaves are generally +chosen for the deposit of eggs, but a few of the insects we are considering +always select the upper surface for this purpose. Thus +the Puss Moth (<a href="#Page_235">page 235</a>), and two or three others resembling it, +though much smaller, known as the Kittens (<a href="#Page_234">page 234</a>), invariably +lay them on the upper surface. And this is the more surprising +since the eggs of these moths are brown or black, and consequently +so conspicuous on the green leaves as to be in danger of being +sighted by the numerous enemies of insects.</p> + +<p>The Hairstreak Butterflies (<a href="#Page_183">page 183</a>) afford another exception to +the general rule, for their eggs are deposited on the <i>bark</i> of the trees +and shrubs (birch, sloe, elm, oak, and bramble) on which their +larvæ feed.</p> + +<p>At the moment each egg is laid it is covered with a liquid +sticky substance, so that it is immediately glued to the leaf or stem +as soon as it is deposited. The sticky substance soon dries, causing +the egg to be so firmly fastened in its place that it is often impossible +to force it off without destroying it completely.</p> + +<p>Some of the <i>Lepidoptera</i> deposit their eggs singly, or in small +irregular clusters; but by far the larger number set them very +regularly side by side, in so compact a mass that it would be +impossible to place them on a smaller area without piling one on +top of another. This is not accomplished with the aid of the sight, +for the insect performing her task with such precision often has her +head on one side of a leaf or stem while arranging her eggs on the +other. If you take the trouble to watch her, you will see that she +carefully <i>feels</i> out a place for each egg by means of the tip of her +abdomen immediately before laying it.</p> + +<p>The eggs are laid by moths and butterflies at various seasons<!-- Page 19 --><span class="pagenum"><a name="Page_19" id="Page_19">[Pg 19]</a></span> +of the year. In some cases they are deposited early in the spring, +even before the buds of the food plants have burst; and the young +larvæ, hatched a few weeks later, commence to feed on the young +and tender leaves. Then, throughout the late spring, the whole of +the summer and autumn, and even till the winter frosts set in, the +eggs of various species are being laid.</p> + +<p>Those deposited during the warm weather are often hatched in +a few days, but those laid toward the autumn remain unchanged +until the following spring.</p> + +<p>In this latter case the frosts of the most severe winter are not +capable of destroying the vitality of the eggs. In many instances +the perfect insect or the larva would be killed by the temperature +of an average winter day, but the vitality of the eggs is such that +they have been subjected to a temperature, artificially produced, of +fifty degrees below the freezing point, and even after this the young +larvæ walked out of their cradles at their appointed time just as if +nothing unusual had occurred.</p> + +<p>Experiments have also been performed on the eggs with a view +of determining how far their vitality is influenced by high temperatures. +We know that the scorching midsummer sun has no +destructive influence on them, but these experiments prove that +they are not influenced by a temperature only twenty degrees below +the boiling point—actually a considerably higher temperature than +is <i>necessary</i> to properly cook a hen's egg.</p> + +<p>Let us now examine a number of eggs of different species, that +we may note some of the many variations in form and colour.</p> + +<p>With regard to colour, we have already observed that the eggs +of a few species are black; but more commonly they are much +lighter—pearly white, green, yellow, and grey being of frequent +occurrence.</p> + +<p>The great variety of form, however, will provide a vast amount +of enjoyment to anyone who possesses a good magnifying lens or +a small compound microscope. Some are globular, others oval; +while many others represent cups, basins, and domes. Then we +have miniature vases, flasks, bottles with short necks, and numerous +figures that must remind a juvenile admirer of the sweet +cakes and ornamental jellies that have so often gladdened his +longing eyes.</p> + +<p>Again, the beautifully sculptured surfaces of a large number are +even more striking than their general shapes. Some are regularly +ribbed from top to bottom with parallel or radiating ridges, and at<!-- Page 20 --><span class="pagenum"><a name="Page_20" id="Page_20">[Pg 20]</a></span> +the same time marked with delicate transverse lines. Others are +beautifully pitted or honeycombed, some ornamented with the +most faithful representation of fine wicker-work, while a few are +provided with a cap, more or less ornamental, that is raised by the +young larva when about to see the world for the first time. A few +of these beautiful forms are here illustrated and named, and another +has already appeared on <a href="#Page_14">page 14</a>, but an enthusiastic young +naturalist may easily secure a variety of others for his own +examination.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_11" id="FIG_11"></a><img src="images/i_037a.jpg" width="300" height="169" alt="" title="" /> +<span class="caption">Fig. 11.—Egg of +the Meadow +Brown Butterfly.</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_12" id="FIG_12"></a><img src="images/i_037b.jpg" width="300" height="173" alt="" title="" /> +<span class="caption">Fig. 12.—Egg of +the Speckled +Wood Butterfly.</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_13" id="FIG_13"></a><img src="images/i_037c.jpg" width="300" height="178" alt="" title="" /> +<span class="caption">Fig. 13.—Egg of +the Vapourer +Moth.</span> +</div> + +<p>It may be surmised from the accompanying illustrations that +the form of the egg is always the same for any one species. +This is really the case, and consequently an experienced entomologist +can often decide on the name of the butterfly or moth that +deposited a cluster of eggs he happens to find in his rambles and +searchings; but in such decisions he is always greatly assisted by a +knowledge of the food plants of the various insects, and sometimes +also by the manner in which the eggs are arranged.</p> + +<p>We have seen that the period during which the <i>Lepidoptera</i> +remain in the egg stage is very variable, and depends largely on +the season in which they were laid; but it is often possible to tell +when to expect the young larvæ by certain changes which take +place in the appearance of the egg. As the horny covering of +the egg is transparent, the gradual development of the caterpillar +from the clear fluid can be watched to a certain extent; but +if you have a microscope, and would like to witness this development +to perfection, proceed as follows.</p> + +<p>Arrange that some butterflies and moths shall lay their eggs on +strips of glass of convenient dimensions for microscopic work—three +inches long by one wide is the usual size for this kind of work. +This is easily accomplished by placing a proper selection of female +insects in a rather small box temporarily lined with such 'slips.' +When a few eggs have thus been secured, all you have to do is<!-- Page 21 --><span class="pagenum"><a name="Page_21" id="Page_21">[Pg 21]</a></span> +to examine them at intervals with your microscope, always using +the reflector so as to direct a strong light <i>through</i> the eggs +from below.</p> + +<p>But even without such an arrangement some interesting +changes are to be observed. As a rule, the colour of the egg +turns darker as the time for the arrival of the infant larva approaches, +and you will often be able to see a little brown or +black head moving slightly within the 'shell.' You may know +then that the hatching is close at hand, and the movements of +the tiny creature are well worth careful watching. Soon a small +hole appears in the side of the case, and a little green or dark +cap begins to show itself. Then, with a magnifier of some kind, +you may see a pair of tiny jaws, working horizontally, and not +with an up-and-down motion like our own, gradually gnawing +away at the cradle, till at last the little creature is perfectly free to +ramble in search of food.</p> + +<p>Strange to say, the young larva does not waste a particle of +the horny substance that must necessarily be removed in securing +its liberty, but devours it with an apparent relish. Indeed, it appreciates +the flavour of this viand so highly that it often disposes +of the whole of its little home, with the exception of the small +circular patch by which it was cemented to the plant. When the +whole brood have thus dispensed with their empty cradles, there +remains on the stem or leaf a glittering patch of little pearly +plates.</p> + +<p>After the performance of this feat the young caterpillar starts +off in life on its own account with as much briskness and confidence +as if it had previously spent a term in the world under the same +conditions; but we must reserve an account of its doings and sufferings +for our next chapter.</p> + + + +<hr /> +<p><!-- Page 22 --><span class="pagenum"><a name="Page_22" id="Page_22">[Pg 22]</a></span></p> +<h3>CHAPTER III +<br /> +<i>THE LARVA</i></h3> + + +<p>In almost every case the young caterpillar, on quitting the 'shell' +of the egg, finds itself standing on and surrounded by its natural +food, and immediately commences to do justice to the abundant +supply.

The illustrious Réaumur, +for example, proved that some of the cabbage +eaters disposed of more than twice their own +weight of food in twenty-four hours, during which +time their weight increased one-tenth.

It evidently feels very uncomfortable. Its +appetite fails, and it remains for a time perfectly quiet in one spot, +having previously spun a little carpet of silk to form a firm foothold +during its temporary indisposition. Its colours have also +become dingy, and anyone, not understanding the character of its<!-- Page 23 --><span class="pagenum"><a name="Page_23" id="Page_23">[Pg 23]</a></span> +growth, might easily be led to suppose that the poor creature was +displaying the earlier symptoms of a serious and perhaps fatal +illness.</p> + +<p>But soon an encouraging symptom is observed. The caterpillar +begins to get restless. Its front segments are turned alternately +right and left, and are also made to swell out much beyond their +normal size. Then in a very short time—often less than a minute +from the first appearances of restlessness—the skin, which has +become somewhat dry and brittle, splits along the back over the +second, third and fourth segments, revealing a new and bright coat +beneath. The caterpillar continues its struggles and, in addition +to the previous movements, causes the swelling to move backward +along the body. This, acting like a +wedge, causes the rent in the old coat +to extend in that direction.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_15" id="FIG_15"></a><img src="images/i_040.jpg" width="300" height="273" alt="" title="" /> +<span class="caption">Fig. 15.—The Caterpillar of +the Dark Green Fritillary +Butterfly.</span> +</div> + +<p>The caterpillar now draws its head +backward, and, with a few convulsive +struggles, pulls the front segments +out of their old skin, and passes its +head out of the rent in the back. +With its foremost segments thus +rendered perfectly free, it walks +straight out of the old garment, +which is left still fixed by the legs to +the silken carpet.</p> + +<p>The larva, although now fresh and smart in its appearance, is +exhausted by these struggles and its prolonged fast. The new skin, +moreover, is very soft and tender, even to the cases of the head +and legs, which are normally very hard.

The hard shell +that covered the head and jaws is perfect in form, and so are the +claws and cases of the legs.

For, according to the accounts of some<!-- Page 24 --><span class="pagenum"><a name="Page_24" id="Page_24">[Pg 24]</a></span> +authoritative observers, the lining of the digestive organs, which is +really a continuation of the outer skin, is cast off (or rather cast +<i>out</i>) at the same time, as are also the linings of the larger breathing +tubes which are presently to be described.</p> + +<div class="figleft" style="width: 245px;"> +<a name="FIG_16" id="FIG_16"></a><img src="images/i_041.jpg" width="245" height="400" alt="" title="" /> +<span class="caption">Fig. 16.—The Caterpillar +of the +Purple Emperor +Butterfly.</span> +</div> + +<p>We have seen that some caterpillars, on quitting their egg cases +(which may really be regarded as the first moult), make their first +meal of the old covering. So also some of them, in their future +moultings, exhibit an apparently useless economy (seeing that they +are surrounded by an abundance of their +natural vegetable diet) by devouring their +old coats! In the face of this fact we can +hardly describe them as strict vegetarians.</p> + +<p>Having thus passed through its first hardship, +the caterpillar has by no means seen +the end of the troubles and dangers that beset +it; for, during its existence in the larval state, +it has to go through a series of three, four, five, +or even six moults, all of which are periods +of considerable inconvenience, and perhaps +even pain, and frequently prove fatal. And +it is by no means an uncommon thing to +meet with the lifeless body of an unfortunate +individual who, as shown by its shabby +appearance and the silken carpet under its +feet, has evidently fallen a victim to the +dangerous process of ridding itself of an old garment.</p> + +<p>But this is only one of the many dangers to which caterpillars +are exposed.

As soon as the young larvæ are hatched +from these eggs, they commence feeding on the fatty substance +stored beneath the caterpillar's skin. They carefully avoid, at +first, attacking the vital organs of their host's body, and in this +way secure for themselves a more lasting supply of fresh food.<!-- Page 25 --><span class="pagenum"><a name="Page_25" id="Page_25">[Pg 25]</a></span> +When the fatty substance is nearly all gone, they eat their way +into the more important structures, of course steadily growing all +the time; and so, even though the body of the caterpillar is rapidly +diminishing, the total bulk shows often no very appreciable decrease +in size.

The first point that strikes our notice is the division of +its body into segments or rings, separated from each other by a +more or less distinct line or slight constriction of the body.</p> + +<p>There are thirteen of these segments, reckoning, as is usual, the +head as the first.</p> + +<p>The head is usually very hard, and often of a much darker +colour than the rest of the body. It is also frequently divided into +two lobes by a couple of oblique lines, between which the parts of +the mouth are situated. The two powerful horizontal jaws, to +which we have already referred, are very hard and sharp, and +curved like a sickle, and therefore splendidly adapted for biting from +the edges of leaves. The head is also provided with a pair of +antennæ, usually very short and inconspicuous and protected by a +horny covering.</p> + +<p>Unlike the perfect insect, the caterpillar has no large compound +eyes, but twelve very small simple eyes, situated on the cheeks, +very near the mouth—six on each +side.</p> + +<div class="figleft" style="width: 300px;"> +<a name="FIG_19" id="FIG_19"></a><img src="images/i_043.jpg" width="300" height="83" alt="" title="" /> +<span class="caption">Fig. 19.—The Caterpillar of +the Angle Shades Moth +(Meticulosa).</span> +</div> + +<p>If you examine them with a magnifier, +you see that each one is provided +with a small and very convex +lens—a lens of very <i>short focus</i>, such +as would be used for the examination +of small objects held very near to +the eye. From this arrangement we should be inclined to conclude +that the caterpillar can see only those objects that are +close to its mouth; and this idea is strengthened if you place +one in a box containing a number of leaves, one of which is +that of its own food plant. It will wander about the box, apparently +looking at every part of every leaf it passes, after the +manner of a very short-sighted individual, and never taking a +general look round. A butterfly or a moth can see a flower in +the distance, for it flies unhesitatingly from one to another in +the straightest and shortest path, but if you place a caterpillar +in the centre of a ring composed of a leaf of its food plant and +nine others from other plants, the chances are (nine to one) that it +will <i>not</i> walk towards what it would like to have.</p> + +<p>Again, the eyes are situated on the <i>lower</i> part of the cheek, +directed slightly downward, and are therefore adapted for seeing +what is just under its jaws as it walks along. Had we no knowledge +whatever of the caterpillar's twelve little eyes, we should probably<!-- Page 27 --><span class="pagenum"><a name="Page_27" id="Page_27">[Pg 27]</a></span> +have thought that it sought out its food by some sense other than +that of vision.</p> + +<p>Another important and interesting feature of the head is the +silk-spinning apparatus, situated under cover of the lower lip. This +consists of two tubular glands, corresponding to our own salivary +glands, the special purpose of which is to secrete a viscid fluid that +solidifies on exposure to air. The opening by which the fluid +escapes is so situated that the caterpillar can easily apply it to the +surface of any object over which it is walking, and then, by drawing +or turning away its head, cause a silken fibre to be produced.</p> + +<p>Some caterpillars make use of this spinning apparatus only on +a few special occasions, but others, more especially some of the +smaller species, seem to have it always in use, so that if at any +time you suddenly start them into the air by giving a smart tap to +the plant or twig on which they rest, they invariably fall slowly on +the end of a growing web, the spinning of which they stop as soon +as they consider they have fallen far enough. Sometimes, as you +are walking through a wood, you will see hundreds, nay, thousands +of little caterpillars thus suspended, swinging gently in the +breeze. Not long since, after only a few minutes' walk among the +trees of Epping Forest, I found I was decorated with several dozens +of these swingers with which I had come into collision—in this +case consisting chiefly of the larvæ of the Green Tortrix Moth +(<i>Tortrix viridana</i>).</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_20" id="FIG_20"></a><img src="images/i_045a.jpg" width="300" height="199" alt="" title="" /> +<span class="caption">Fig. 20.—Walking Leg +of a Caterpillar.</span> +</div> + +<p>Now let us examine the caterpillar's limbs.

Thus they are termed 'pro-legs,' 'temporary +legs,' 'false legs,' and 'abdominal legs;' but if you watch a +caterpillar as it walks up a stalk or along the edge of a leaf, +you will certainly agree that the term 'clasper' is everything that +could be desired. But why not call them legs, seeing that they +are used in walking? The reason is that they differ in many +respects from the three foremost pairs of +limbs as regards structure, persistency, and +function. The true legs, as we have called +them, continue to exist, though concealed, in the chrysalis state, +and again appear, far more perfectly developed, in the butterfly +or moth, but the claspers are no more to be seen after the +caterpillar has passed into the quiescent stage. We have noticed, +too, that the true legs are pointed and clawed, also that they are protected +by a hard and horny covering; but examine a large caterpillar, +holding it between the fingers and thumb with its under side +uppermost, and you will soon see that the claspers are not at all hard, +but soft and fleshy; not pointed, but often terminating in a broad +flat circular surface. You will also observe, as the creature struggles +to escape from your grasp, and tries to get a hold on something with +its claspers, that these limbs, if we may so call them, are retractile, +and are sometimes completely drawn into the body. Finally, +examine the broad end of a clasper with a magnifier, and you will<!-- Page 30 --><span class="pagenum"><a name="Page_30" id="Page_30">[Pg 30]</a></span> +see it surrounded by a circle of little hooks, turning in all directions. +You will no longer wonder how it is that a caterpillar can hold so +tenaciously to a piece of twig that it is often almost impossible +to remove it without injury.</p> + +<p>Now put your caterpillar down, so that you may observe its gait. +If it happens to be one with the full complement of sixteen limbs, +you see that at each stride it makes but little progress. The +segments contract and relax alternately and in succession, thus +sending a series of wave-like motions along the body, and urging +onward the front segments while the claspers keep the hinder +portion firmly fixed.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_26" id="FIG_26"></a><img src="images/i_047.jpg" width="300" height="400" alt="" title="" /> +<span class="caption">Fig. 26.—The Claspers +of a Caterpillar.</span> +</div> + +<p>But if your caterpillar is one of the Geometers, with only two, +or perhaps three, pairs of claspers, the mode of procedure is very +different. The creature stretches its body out at full length, often +raising its head high in the air, and swinging +its long body right and left with a most +furious motion, as if to hastily scan the +neighbourhood. Then, having satisfied +itself as to the <i>direction</i> of its proposed +course (which, by the way, is often changed +considerably at almost every stride), it +holds on by the true legs and pulls its +hinder quarters forward till the body forms +almost a closed loop, with the fourth segment +nearly touching the ninth. The +claspers now become the holdfasts. The +little hooks with which they are provided +are firmly fixed to the surface on which it is walking; and the +body being again straightened out to its utmost length, the same +manœuvre is repeated. So, you see, the insect progresses by +strides equal in length to about six segments of the body, and +these the longest segments generally; and the rate at which the +strides succeed each other, especially in some of the smaller species, +is really astonishing.</p> + +<p>We have seen the caterpillar in the act of taking its walk, and +now we will give it a twig of its food plant so that we may see it +feed. It walks up the twig without hesitation—for caterpillars +(excepting those which feed on roots) always seem to move upward +when in search of food—and soon finds itself on a leaf. Over this +it walks till it reaches the edge; and, grasping the edge firmly +between the claspers, so as to give perfectly free play to its legs and<!-- Page 31 --><span class="pagenum"><a name="Page_31" id="Page_31">[Pg 31]</a></span> +head, it stretches its body at full length, and takes a series of bites +as it brings its head backward in a curve. When the head has +thus been brought close to its fore legs, the body is again extended, +and the same ground is gone over again.</p> + +<p>If the caterpillar is a fairly large and hardy one, it will bite +through the smaller veins, and perhaps even the larger ones; but +the smaller species often change their position on reaching a +moderately thick vein, and so devour little else than the soft cellular +substance of the leaf. In any case, it is astonishing to see how +rapidly the leaf disappears under the influence of the powerful jaws +and marvellous digestive apparatus of the hungry grub.</p> + +<p>Those who take a delight in watching the <i>movements</i> of caterpillars +are sure to be interested in observing them when at rest; +for at such times the various attitudes assumed are as pleasing +and instructive as are their active moments. And these attitudes +are all the more interesting on account of the mimicry by which +the creatures often baffle their numerous enemies. We may +profitably spend a little time in studying a few cases in point.</p> + +<p>Many species, when at rest, fix themselves by means of their +claspers to a small twig or leaf stalk, or on the midrib of the leaf +itself. Here they remain perfectly still, with their bodies perfectly +straight or with head slightly raised. I need hardly say that these +generally fix themselves on the <i>under</i> side of the leaves and stalks, +thus securing themselves against the attacks of the feathered foes +above. But some birds are equal to the caterpillars in this matter; +and it is really amusing to see them hopping about beneath the +leaves in our gardens, every now and again slyly turning one +eye upward, and smartly plucking an unwary grub from its resting +place.</p> + +<p>The precautions of the caterpillar, however, do not end merely +with the selection of an under surface. You will find that the +bright green species invariably settle on a leaf or a <i>green</i> stalk, +while the darkly coloured insects often choose a twig covered with +a brownish bark. Some even make for the <i>trunk</i> of the tree on +which they feed, and here remain quite still in a vertical position, +so that they look just like a ridge in the bark, the colour of which +is faithfully imitated by their skin. Further, many of the caterpillars +that resort to this stratagem have bodies that are notched +or knotted and spotted in such a manner that the resemblance to +their surroundings is so perfect as to defy any but the most +experienced eye. And even this is not all, for a number of these<!-- Page 32 --><span class="pagenum"><a name="Page_32" id="Page_32">[Pg 32]</a></span> +mimics of the insect world never venture to feed by day, but take +in their quantum of provisions during the dark hours, and practise +their deceptions throughout the day.</p> + +<p>Most of the Geometer caterpillars, of which we have already +spoken, are well trained in the art of deception. You are out +on a caterpillar hunt, and engaged in carefully turning over the +twigs of the hazel or some other shrub, so that you may the more +readily examine the under surfaces of the leaves. At last you lay +hold of a small broken twig for this very purpose. To your +astonishment it is very soft, and readily bends between your +fingers. You look more closely at this peculiar piece of stick, and +find, to your surprise, that you have grasped a looper caterpillar +that was standing out at an angle just like a broken twig, +supported by its two pairs of claspers, and coloured and knotted +exactly like the little branch on which it rested.</p> + +<p>At other times you meet with little green caterpillars of the +same group, supporting themselves in exactly the same manner on +a small twig, and looking just like a leaf stalk from which the +blade had fallen or been devoured.</p> + +<p>What a wonderful power is exhibited in the grasp of the +claspers and the tension of the muscles, enabling the caterpillar to +fix itself and retain its position for so long a time! Imagine an +acrobat fixing himself by his hands on an upright pole, throwing +out his body at an angle, and without any further support retaining +his position motionless for several hours!</p> + +<p>Other experiences of the larva hunter are equally interesting +and, perhaps, even more tantalising. He is engaged in very +cautiously turning over the leaves of a certain food plant from +which he hopes to obtain the larva of a much-coveted species. +Then, just as his eye catches a glimpse of the very object of his +search, down falls the caterpillar, rolled up into a little ball, among +the herbage below. This latter is diligently and patiently examined. +But no, the anticipated prize is nowhere to be seen. +It is probably a green one, and this adds to the difficulty of the +patient entomologist. Then, as he carefully separates the low +herbs, hoping to find the spot where the larva had fallen, the +insect, rolled up into a compact little ball, only sinks deeper and +deeper into the maze.</p> + +<p>Many caterpillars avoid capture in this manner, while others +seek to avoid detection by remaining perfectly motionless, even +when roughly handled. They allow themselves to drop from their<!-- Page 33 --><span class="pagenum"><a name="Page_33" id="Page_33">[Pg 33]</a></span> +resting place on the slightest sign of danger, and, when the alarm +is over and all is quiet again, they ascend the food plant and +resume their position.</p> + +<p>Some caterpillars not only rest, but even feed under cover, +quite secure from most, if not all, of their enemies. Several of +them feed on roots, and many a farmer can relate sad experiences +of the havoc committed by these caterpillars on his turnips and +other crops.

Take a few out of +their self-made homes, place them on a sprig of the food plant, +and you will soon have the pleasure of seeing one start its extraordinary +work.</p> + +<p>At first it spins a number of threads stretching from the edge of +a leaf to about the middle of the surface. These threads are not +tight by any means, and the leaf is, as yet, unchanged in position. +But now the little mechanic exhibits a tact that almost seems to +prove a knowledge of the principles of its art. Each thread in turn +is pulled <i>at right angles</i> at its middle, and then fastened by means +of the creature's spinneret. Each time this is done the edge of +the leaf is bent round <i>a little</i>; and when at last the cylinder is +completed, a number of other threads are stretched across from the +scroll to the flat part of the leaf to secure it firmly in its place.</p> + +<p>Many caterpillars are solitary in their habits: that is, they are +always found singly, whether walking, resting, or feeding. But a +large number of species are gregarious, living in dense clusters +either throughout their larval state or, perhaps, only while young. +In many such cases it is difficult or even impossible to find any +reason for this gregarious tendency—to discover any advantage +that the insects may derive from the habit. Many species, however, +are true co-operators in the defence of their communities. +The caterpillars of such live in clusters, sometimes several scores +in each, and all help in the spinning of a complicated mass of silk +fibres, which, with the leaves and twigs they join together, form a +safe home in which they can rest, feed, or change to the chrysalis +state. In early summer hundreds of such caterpillar 'nests' are +to be seen in many of our hawthorn and other hedgerows.</p> + +<p>Before closing our general account of the caterpillar we must +have a word to say about the breathing apparatus, more especially +as in our future descriptions we shall frequently have to mention +the colours and markings which surround the openings in its body +through which the air supply is admitted.</p> + +<p>If you examine the sides of the segments of a caterpillar, using +a lens if the insect is a small one, you will observe some little<!-- Page 35 --><span class="pagenum"><a name="Page_35" id="Page_35">[Pg 35]</a></span> +round holes, often inclosed in a ring or a patch of some prominent +colour. These are the <i>spiracles</i> or openings of a series of air tubes +called <i>tracheæ</i>. These latter divide and subdivide within the body +of the caterpillar, the branches of one often uniting with those of +another, thus forming a really complicated arrangement of air pipes +by which the supply of oxygen is distributed.</p> + +<p>A microscopic examination of a portion of one of the tracheæ +will show that its walls are supported by an elastic spiral of a firm +substance. This arrangement serves to keep the air passages open, +and secures for the caterpillar a free supply of air at times when a +contraction of the segments would otherwise cause the tubes to +collapse.</p> + +<p>There are nine spiracles on each side of the caterpillar's body, +and never more than one in the side of the same segment. The +head, which we have been regarding as the first segment, has no +spiracles. The second segment has a pair—one on each side. +There are none in the third and fourth; but all the segments, from +the fifth to the twelfth inclusive, have each a pair; the last +(thirteenth) segment has none.</p> + +<p>We have already observed the general arrangement of the caterpillar's +limbs; but perhaps it may be interesting and even convenient +to the reader to give here a little table that will show at a +glance the disposition of both limbs and spiracles.</p> + + + +<div class="center"> +<table border="0" cellpadding="4" cellspacing="0" summary="Disposition of caterpillar limbs and spiracles."> +<tr><td align="left">First</td><td align="left">segment—head</td><td align="left">Two short antennæ, two jaws, and twelve eyes.</td></tr> +<tr><td align="left">Second</td><td align="left"> "</td><td align="left">Legs and spiracles.</td></tr> +<tr><td align="left">Third</td><td align="left"> "</td><td align="left">Legs only.</td></tr> +<tr><td align="left">Fourth</td><td align="left"> "</td><td align="left">Legs only.</td></tr> +<tr><td align="left">Fifth</td><td align="left"> "</td><td align="left">Spiracles only.</td></tr> +<tr><td align="left">Sixth</td><td align="left"> "</td><td align="left">Spiracles only.</td></tr> +<tr><td align="left">Seventh</td><td align="left"> "</td><td align="left">Spiracles, and sometimes claspers.</td></tr> +<tr><td align="left">Eighth</td><td align="left"> "</td><td align="left">Spiracles, and sometimes claspers.</td></tr> +<tr><td align="left">Ninth</td><td align="left"> "</td><td align="left">Spiracles, and sometimes claspers.</td></tr> +<tr><td align="left">Tenth</td><td align="left"> "</td><td align="left">Spiracles, and generally claspers.</td></tr> +<tr><td align="left">Eleventh</td><td align="left"> "</td><td align="left">Spiracles only.</td></tr> +<tr><td align="left">Twelfth</td><td align="left"> "</td><td align="left">Spiracles only.</td></tr> +<tr><td align="left">Thirteenth</td><td align="left"> "</td><td align="left">Claspers only, and these occasionally absent.</td></tr> +</table></div> + +<p><!-- Page 36 --><span class="pagenum"><a name="Page_36" id="Page_36">[Pg 36]</a></span></p> + +<p>We must now watch the caterpillar through its later days, to +see how it prepares for passing into the pupal stage, and to +witness the various interesting changes that take place at this +period.</p> + +<p>When fully grown, it ceases to eat, and begins to wander about +in search of a convenient spot for the coming event. Its colours +fade, and the body becomes appreciably smaller, especially in length, +as it ejects the whole contents of its digestive apparatus. According +to some accounts, it even evacuates the lining of the intestines +with their contents.</p> + +<p>A great variety of situations are chosen by the different species +at this time. Some will fix themselves on their own food plant, +and there remain till they finally emerge in the perfect state, +suspending themselves from a silken carpet, hiding themselves +in a rolled leaf, or constructing a cocoon of some kind. A large +number walk down the food plants, and undergo their changes +in moss that happens to lie at the foot; or construct a cocoon +on the surface of the ground, utilising for the purpose any decayed +leaves, fragments of vegetable matter, or pieces of earth or small +stones. Many seek a further protection than this, and burrow +into the soil, where they either lie in a little oval cell that they prepare, +or in a cocoon constructed by spinning together some particles +of earth. Again, there are those caterpillars, chiefly of butterflies +that frequent our gardens, which find their way to the nearest wall +or fence, and there secure themselves in a sheltered nook. We +will watch a few of these varied methods of procedure, taking as +our first instance the caterpillar of the common Large White or +Cabbage Butterfly.</p> + +<p>When fully fed, this larva seeks out a sheltered spot, generally +selecting the under surface of some object, or of the ledge of a +wall or fence. Sometimes it will not even leave its food plant, +though it generally walks some considerable distance before a suitable +shelter is found. Having satisfied itself as to the site of the +temporary abode, it sets to work at spinning a silken carpet. At +first the threads spread over a rather wide area, and seem to be +laid in a somewhat irregular and aimless manner; but after a little +time its labours are concentrated on one small spot, where it spins +several layers of silk fibres.</p> + +<p>This done, it fixes the little hooks of the claspers firmly in its +carpet bed, and then proceeds with a highly interesting movement. +It is not satisfied with only the one mode of suspension. In fact,<!-- Page 37 --><span class="pagenum"><a name="Page_37" id="Page_37">[Pg 37]</a></span> +this alone would hardly be safe, for when it casts its skin, as it is +shortly about to do, its claspers will all disappear; and although it +afterwards secures itself by the 'tail,' it would be dangling in such +a manner as to swing with every breeze—a very unsatisfactory +state of affairs, especially with those that pupate late in the summer +and remain in the pupal state throughout the winter storms.</p> + +<p>Its next procedure, then, is to make a strong silk band round the +middle of its body, so as to keep it close to the surface against which +it rests. But how is this to be done? It bends its head round till +the spinning organ can be applied to a point close beside the middle +of its body. Here it fixes one end of a thread; and then, gradually +twisting its body, brings its head round to the other side, still keeping +it close to the same segment, and fastens the other end of the +thread exactly opposite the point at which it started.</p> + +<p>The head is now brought back to its former position, thus +adding another thread to the band; and the process is repeated +several times, till at last the caterpillar is satisfied with the thickness +and strength of the cord formed.</p> + +<p>Now it straightens out its body as if to rest from its labours; +but the work is not yet complete. Soon it exhibits much restlessness. +Its foremost segments are seen to shorten, and consequently +become thicker. Then the skin splits, and the last moult of the +caterpillar commences. The movements that follow are exactly +similar to those we have already described in connection with one +of the earlier moults: the alternate and successive contractions of +all the segments gradually force back the old coat, and this is +finally thrown entirely off by a somewhat vigorous wriggling of the +'tail.'</p> + +<p>Then, for a moment, the creature is supported only by its silken +cord. But this lasts <i>only</i> for a moment. For, as soon as it is +quite free from the old garment, it applies its tail to the densest +part of the carpet it had prepared at the start, and secures its hinder +extremity by means of little hooks.</p> + +<p>But what a change has now come over the creature! It is no +longer a caterpillar. Its head is no longer distinct, although we +can readily make out the positions of the eyes. Its mouth and +jaws have quite disappeared, and the legs and claspers are apparently +gone. The three segments that bore the legs are no longer distinctly +separable, though in reality they still exist. The head and thorax +are peculiarly shaped; and, instead of being cylindrical, are angled +and ridged; but, beneath the soft greenish skin—the new garment—we<!-- Page 38 --><span class="pagenum"><a name="Page_38" id="Page_38">[Pg 38]</a></span> +can discern the outline of a pair of small wings, and see a +proboscis and a pair of long antennæ. Also the six long legs of the +future butterfly can be traced with care.</p> + +<p>The abdomen is conical in form, coming to a sharp point at +the end, and its segments are quite distinct.</p> + +<p>No stranger to the metamorphoses of insects would connect +the present form with that of a caterpillar; they are so very +unlike. And yet the time occupied in the whole change, from the +spinning of the carpet, does not occupy more than about thirty or +thirty-five hours.</p> + +<p>The apparent suddenness of this change is really surprising, but +in reality the transformation is not nearly so sudden as it appears. +Dissection of a caterpillar a few days before the final moult is due +will show that the changes are already going on. In fact, a +simple removal of the skin will prove that the organs of the +future butterfly are developing. Still, in proportion to the short +time occupied, the change is extremely great; and it may reasonably +be inquired, Why so great a change within so short a space of +time?—why is not the change continued steadily and equally +through the larval existence? The reason has already been hinted +at. Caterpillars are living eating machines, whose office is to +remove excess of vegetable matter. Consequently they must have +their jaws and bulky digestive apparatus in full development to the +end. If these organs were to <i>gradually</i> disappear as the caterpillar +reaches its non-eating stages, it would simply be starved to death. +So the change from the larval to the pupal state, which we may +regard as the final moult of the caterpillar, is a far greater change +than any of the preceding ones, and occupies a proportionately +longer time, although it is principally confined to the last few days +of the caterpillar life.</p> + +<p>A number of caterpillars, and especially those of the butterflies, +suspend themselves when about to change; and the peculiarities of +the modes adopted must be left for our descriptions of species in a +future chapter; but we will find room here for one more interesting +example, taking this time the larva of one of the commonest of the +Vanessas (<a href="#Page_166">page 166</a>)—the Small Tortoiseshell Butterfly.</p> + +<p>The caterpillars of this insect are gregarious when young; and +if ever you meet with one, you are almost sure to be able to obtain +a hundred or so without much searching. But as they grow older +they feed singly, yet generally without straying very far from their +birthplace.<!-- Page 39 --><span class="pagenum"><a name="Page_39" id="Page_39">[Pg 39]</a></span></p> + +<p>When full grown they sometimes stray to a neighbouring plant +or fence to undergo the change to a chrysalis, but more commonly +they are perfectly satisfied with the protection afforded by the leaves +of their food plant. We will now watch one of these as we did the +larva of the Large White Butterfly.</p> + +<p>Of course the under side of the leaf is chosen. Here a silken +carpet is spun as before described; but the caterpillar, instead of +clinging with <i>all</i> its claspers, suspends itself in a vertical position +by its hindermost pair only.</p> + +<p>Here it hangs, head downwards, awaiting the coming events. +The splitting and casting of the skin goes on just as in the case of +the Large White, but there is this puzzle to be solved: how +can the insect shuffle itself out of its old coat without falling to the +ground, leaving the cast-off garments still hanging by the hooks +of the claspers? This really seems a matter of impossibility, since +the little hooks which alone suspend the insect are thrown off with +the skin of the claspers.</p> + +<p>The thing is managed in this way. As the skin slowly splits +through the wrigglings of the apparently uncomfortable occupant, +it is gradually pushed backward—that is, upward—till it is in a +shrivelled condition, and the body of the insect is nearly free. But +the chrysalis thus brought to light is provided with little hooks on +the end of its 'tail' by which it can attach itself to the irregularities +of the crumpled coat. Its conical abdomen is also very flexible, +and it can, by bending this, seize hold of a ridge in the skin, +holding it between the segments. Thus, although practically quite +free from the old garb, it never falls to the ground.</p> + +<p>There is now, however, another point to be attended to. The +newly formed chrysalis desires to be entirely independent of its +cast-off skin, and to suspend itself directly from the silky carpet it +has prepared. To this end it works steadily for a time, alternately +bending its supple abdomen from side to side, gripping the folds of +the skin between the segments, pulling its body a little higher at +each movement, and securing itself at each step by the little hooks +at its extremity.</p> + +<p>So it climbs, and at last it reaches the network of silk fibres, and +thrusts the tip of its abdomen among them till some of the hooks +have taken hold. Not satisfied with this, it turns its body round +and round to get the little hooks so entangled between the silk +fibres that a fall is impossible, and in so doing it frequently pushes +the old skin out of its place so that it falls to the ground.<!-- Page 40 --><span class="pagenum"><a name="Page_40" id="Page_40">[Pg 40]</a></span></p> + +<p>Although the caterpillars of this species do not show any great +gregarious tendency when nearly full fed, yet it is not an uncommon +thing to find several hanging from the under surface of +one leaf, all being attached to the one common carpet at which all +had worked. And when bred in confinement, a number will often +spin in company in a corner of their cage. I have thus obtained a +cluster of thirty-seven pupæ, all hanging by the 'tails' to the +same mass of silk, which was so small that they formed quite a +compact mass of beings with their tails close +together.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_28" id="FIG_28"></a> +<img src="images/i_057a.jpg" width="300" height="190" alt="" title="" /> +<span class="caption">Fig. 28.—The Cocoon of the +Emperor Moth.</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_29" id="FIG_29"></a><img src="images/i_057b.jpg" width="300" height="400" alt="" title="" /> +<span class="caption">Fig. 29.—The Cocoon +of the Six-spotted +Burnet (Filipendulæ).</span> +</div> + +<p>We have seen that the Large White Butterfly +makes itself secure by a silk band round its +middle, while the 'Tortoiseshell' is fixed only +by its tail.

Here it is the perfect insect that +braves the winter, and not the chrysalis.</p> + +<p>There is a great variety in the means taken by the caterpillars +of moths to protect themselves during their metamorphoses, but we +shall have space for only a few illustrations.</p> + +<p>A clever cocoon is spun by the larva of the Emperor Moth +(<i>Pavonia</i>). It is pear-shaped, and composed of a brownish silk; +and is so constructed that the newly emerged moth can easily walk +out of the small end without breaking a fibre, while the entry of an +insect enemy from without is impossible.</p> + +<p>This is managed as follows. A number of rather stiff threads +are made to project from the small end of the cocoon, and these +converge as they pass outward so that the ends are all near<!-- Page 41 --><span class="pagenum"><a name="Page_41" id="Page_41">[Pg 41]</a></span> +together. The other portions of the cocoon are of compact silk, +and any insect intruder that ventures to enter by what we may +almost term the <i>open</i> end is met by a number of spikes, as it were, +that play on it at every attempt. Many of these wonderful cocoons +may be found during the winter months attached to the food plants +of this insect.</p> + +<p>Of the silken cocoons spun by various caterpillars some are so +thin and light that the chrysalis can easily be seen through them, +and others are so densely woven as to be quite opaque. A +great difference is also to be observed in the adhesive power of the +silk fibres. In some cases little threads of silk can be pulled off +the cocoon; but some of them, that of the Oak Eggar (<a href="#Page_229">page 229</a>) for +example, look as if they had been constructed of paper rather than +of silk, because, at the time of spinning, the moist silk fibres stuck +so closely together.</p> + +<p>An extreme case of this character is to be met with in the +cocoon of the Puss Moth (<a href="#Page_235">page 235</a>); for here the fluid from the +spinneret of the caterpillar does not harden at once on exposure to +air, and so the threads become thoroughly united together, thus +forming a solid gluey cocoon.</p> + +<p>When the Puss caterpillar is about to change, it descends the +tree (poplar, willow, or sallow) till it is within a few feet of the +ground. Then it commences gnawing away at the bark, at the +same time cementing all the pieces together with the gluey substance +from its spinning glands. In this way it surrounds itself +with a very hard cocoon, which so closely resembles the surrounding +bark in colour that detection is difficult indeed.</p> + +<p>But how will the caterpillar proceed if it is removed from its +native tree and has no bark to gnaw? That you can easily answer +for yourself, or rather Puss will answer it for you. Go and search +among the poplars, willows and sallows in the month of July. You +may possibly come across a caterpillar that is just in the act of +creeping down the bark in search of a resting place; but if not you +may be successful in obtaining a few either by examining the twigs, +or you may start them from their hiding places by smartly tapping +the smaller branches with a strong stick.</p> + +<p>Having secured one or more larvæ, take them home, and they +will give some rather novel performances. If they are not fully +grown, you must supply them with fresh leaves every day till they +refuse to eat; and then is the time for your experiments. Shut one +in a little wooden box, and you will have the pleasure of watching it<!-- Page 42 --><span class="pagenum"><a name="Page_42" id="Page_42">[Pg 42]</a></span> +construct a cocoon of chips of wood that it has bitten out with its +powerful jaws, all joined together into a hard shell by means of +transparent glue. Shut another Puss in a glass vessel—a tumbler, +for instance—either by placing it under the inverted vessel, or by +covering over the top. Perhaps it will not be superfluous to mention +that, should you place it under an inverted vessel, this vessel +should not stand on a polished table, for, whatever be the material, +unless <i>extremely</i> hard, it is sure to be utilised in the manufacture +of the cocoon.</p> + +<p>Let us suppose, then, that the caterpillar is under an inverted +tumbler that stands on a plate or saucer. Now it is for <i>you</i> to +decide what material shall be used in the construction of the new +home. Give Puss some fine strips of brightly coloured ribbon, +and it will construct a very gaudy house by gluing them together. +Or, provide it with sawdust, pieces of rag, glass beads, sand, paper, +anything in fact; and the material will be 'made up' into a +cocoon more or less ornamental according to the nature of the supply.</p> + +<p>But what if you give it <i>nothing</i> with which to work, and so +inclose it that nothing its jaws can pierce is within its reach? +For instance, shut it in with tumbler and saucer as before, inverting +the former on the latter, and give it no material whatever. +What will it do now? We will watch and see.</p> + +<p>At first it is very restless, and walks round and round the edge +of the tumbler, evidently a little dissatisfied with the prospects. +Then, after a little while, the events of nature transpiring in their +fixed order regardless of trivial mishaps, the glutinous fluid begins +to flow from the creature's spinning glands, and it moves about in +a somewhat aimless fashion, applying the transparent adhesive +matter both to tumbler and saucer.</p> + +<p>It seems now to become a little more reconciled to its unnatural +surroundings; and, making the best of bad matters, keeps its +body in one place, and starts the construction of a ridge or barrier +all round itself. By the continued application of the creature's +spinneret this barrier is made gradually thicker and higher, till at +last the overhanging sides meet and the caterpillar is inclosed in +its self-constructed prison. But the walls of this prison are so +transparent that every movement can be watched; and, after the +insect has spent a few days in completing the cocoon, we can see +it cast off its old skin, and appear in the new garb of a fine +greenish chrysalis.</p> + +<p>Its soft green skin soon hardens and turns to a rich dark brown<!-- Page 43 --><span class="pagenum"><a name="Page_43" id="Page_43">[Pg 43]</a></span> +colour, and it settles down for a long rest lasting till the following +May or June.</p> + +<p>When the whole operation of building is completed, lift up the +tumbler, and up will come the saucer too. The two are firmly +glued together by the substance secreted; and the power of this as +a cementing material will be well illustrated if you endeavour by +mere pulling force to separate the two articles.</p> + +<p>The Puss is not the only caterpillar that works up a foreign +material with the contents of the spinning organs. There are +several others, in fact, that use for this purpose fragments of wood +or other parts of the food plants; and a still larger number bind +together leaves, fresh or dead, or particles of earth or other matter. +Several such cocoons will be described in our accounts of +individual species in another chapter. We shall now devote a +little space to a few general remarks on the chrysalides and the +final metamorphosis of butterflies and moths.</p> + + + +<hr /> +<p><!-- Page 44 --><span class="pagenum"><a name="Page_44" id="Page_44">[Pg 44]</a></span></p> +<h3>CHAPTER IV +<br /> +<i>THE PUPA OR CHRYSALIS</i></h3> + + +<p>As soon as the last moult of the caterpillar is over, the chrysalis +that had already been developing under the cover of the old skin +is exposed to full view; and although the perfect insect is not to +be liberated for some time to +come, yet some of its parts are +apparently fully formed.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_30" id="FIG_30"></a><img src="images/i_061a.jpg" width="300" height="368" alt="" title="" /> +<span class="caption">Fig. 30.—The +Pupa of the +Privet Hawk +(<i>Ligustri</i>).</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_31" id="FIG_31"></a><img src="images/i_061b.jpg" width="300" height="282" alt="" title="" /> +<span class="caption">Fig. 31.—The +Chrysalis of +the Large +White Butterfly +(<i>Brassicæ</i>).</span> +</div> + +<p>The newly exposed skin of +the chrysalis is very soft and +moist, but as it hardens it forms +a membranous or horny covering +that protects and holds +firmly in place the trunk and +the various limbs and appendages +that are distinctly to be +traced on the under surface.</p> + +<p>If, however, you examine a +chrysalis directly after the moult +is over, you will often find that +the wings, antennæ, proboscis, +and legs of the future butterfly +can be easily separated from +the trunk of the body on which +they lie by means of a blunt needle, and can be spread out so as to +be quite free from that surface.</p> + +<p>In form the chrysalides of butterflies and moths are as variable +as the caterpillars.

The caterpillars of +these are remarkable for their very hairy bodies, often ornamented<!-- Page 46 --><span class="pagenum"><a name="Page_46" id="Page_46">[Pg 46]</a></span> +by several bold brush-like tufts. The chrysalides are also hairy; +and several of the moths themselves are not only thickly clad with +shaggy hair, but a bold tuft often tips the abdomen.</p> + +<p>We must not leave these few remarks on the characters of +chrysalides without a mention of the brilliant spots of burnished +gold that decorate the pupæ of certain butterflies. This is the +feature that led to the invention of the term <i>chrysalis</i>, which is +derived from the Greek word <i>chrysos</i>, meaning <i>gold</i>. For the +same reason the term <i>aurelia</i> has been applied to the pupæ of +<i>Lepidoptera</i>, this being derived from <i>aurum</i>—the Latin name for +gold.</p> + +<p>Strictly, then, these two terms apply only to the pupæ of a +certain number of the butterflies; but the former is now generally +used to designate the pupæ of all the <i>Lepidoptera</i>, and is even extended +to the corresponding stages of insects of other orders.</p> + +<p>If you examine one of these gold-speckled chrysalides, the +brilliant metallic lustre seems to belong to the outer surface, just +as if certain spots had been tipped with real gold; but after the +butterfly has quitted its case the beautiful golden spots are gone. +This proves that the metallic appearance is not due to reflection +from the outer surface of the chrysalis, but to a reflection from some +structure beneath it. This latter is a very thin membrane which +lies just under the outer transparent covering of the chrysalis.</p> + +<p>The period during which the <i>Lepidoptera</i> remain in the chrysalis +state varies very considerably in different species, and also +depends more or less on the temperature. As a rule, when a caterpillar +pupates before the end of the summer, it remains dormant +in the pupal condition for only a few weeks; but, if late in the +summer or in the autumn, it remains in this condition throughout +the winter, and emerges in the following spring or early summer.</p> + +<p>Both these conditions are illustrated in the life history of the +Large White or Cabbage Butterfly—an insect with which we have +already become acquainted. We get two distinct broods of this +butterfly every year, the first appearing in May and the second in +August. The eggs of the first brood hatch in about a fortnight, and +the larvæ are full grown about four weeks later. These then change +to chrysalides, from which the perfect insects (the second brood) +emerge in a few weeks—the period varying slightly with the temperature +of the season. From the eggs of this second brood we +get another invading army of cabbage eaters that change to pupæ +late in the summer. These remain dormant till the following<!-- Page 47 --><span class="pagenum"><a name="Page_47" id="Page_47">[Pg 47]</a></span> +April, and may be found in numbers throughout the winter, attached +to the walls and fences of kitchen and market gardens.</p> + +<p>If, then, the pupæ of the same species are so influenced by the +temperatures of the seasons, can we limit or prolong the period +of quiescence by subjecting them to high or low temperatures +artificially produced? Most certainly we can; and every practical +entomologist knows how to obtain the perfect butterflies and +moths of certain species long before their appointed times, or, +if he desires it, to compel them to remain in their dormant stage +long after the natural period has terminated.</p> + +<p>Sometimes an enthusiastic insect hunter obtains a large number +of what we may term 'winter pupæ,' by collecting and breeding +various species. He also anticipates a number of successful captures +of perfect insects during the following summer. Thus, from two +distinct sources, he obtains a goodly assortment of butterflies and +moths, the setting, preserving, and arranging of which entails an +immense amount of home work.</p> + +<p>Under such circumstances he will sometimes endeavour to cause +some of his pupæ to emerge before their accustomed time, so that he +may get some of his insects 'on the boards' before his field work +is in full swing, and so avoid a rush, or prevent the loss of insects +that will be spoiled before he has time to take them in hand.</p> + +<p>This process of hurrying up his pupæ he calls 'forcing,' and +simply consists in keeping them for a time in a warm room or hothouse +where the high temperature is pretty constant.</p> + +<p>On the other hand, the entomologist may desire to try the effect +of a continued <i>low</i> temperature on his pupæ. This he can do by +placing his pupæ in an ice house. Such experiments have often +been performed, and the results are very interesting. In some +cases the emergence of the perfect insect has been delayed for many +months, and even years; and then, after an exposure to a normal +temperature lasting only a week or two, the winged insect has +made its appearance just as if nothing unusual had happened.</p> + +<p>Such are the effects of <i>extreme</i> temperatures on the duration +of the chrysalis state; and we naturally infer, from such results, +that the pupa under natural conditions is influenced, though in a +lesser degree, by the variations experienced with the seasons, +especially in such a fickle climate as our own.</p> + +<p>The insect hunter has always to bear this in mind, and particularly +so when he sets out on a search for certain desired species. +Suppose, for example, he has set his mind on the capture of a<!-- Page 48 --><span class="pagenum"><a name="Page_48" id="Page_48">[Pg 48]</a></span> +certain butterfly that <i>usually</i> appears in the <i>first</i> week in May. +Before finally naming the day, he has to consider what the weather +has been during the last few weeks, and if he finds that this has +been much warmer than the average for the corresponding periods +in the past, he selects a day in <i>April</i>, earlier or later according to +the difference between the present season and the average.</p> + +<p>If he does not pay due attention to such considerations, he will +sometimes find that all the insects netted are shabby and much +worn, even though, under average conditions, he would be catching +newly emerged and brilliant specimens. This, then, will explain +how it is that we so often see in entomologists' periodicals startling +accounts of 'early captures,' and of the appearance of certain insects +late in the season that <i>ought</i> not to have emerged till the following +summer.</p> + +<p>I will give just one illustration of these variations. The beautiful +Orange Tip Butterfly (<a href="#Frontispiece">Plate I</a>, fig. 7) generally appears about the +middle of May in the southern counties. Farther north it is of +course a little later. In the north of England it has been taken in +June; and in Scotland as late as July. On the other hand, I have +taken it in Gloucestershire as early as March, on a rather bleak +day with a cold east wind; and, withal, in a field on the slope of the +Cotswolds fully exposed to the unfavourable breeze; but it was +evident that, in this case, the butterfly had been enticed from +its winter quarters by the milder weather of the few previous +weeks.</p> + +<p>It may be as well, in passing, to observe that it is not only the +pupa that is influenced by temperature. The hatching of eggs may +be forced by high temperatures, or be retarded by exposure to cold; +and in nature the period of incubation varies with the seasons. +The larvæ, too, grow faster or more slowly, or pupate earlier or +later from similar causes. And so no very definite date or period +can be assigned to any one stage of any insect.</p> + +<p>Now let us return to one of the chrysalides that we have already +watched through the earlier stages of its existence, and follow it in +its future development.</p> + +<p>It is now, as we say, in its quiescent or dormant condition, but +we must not suppose that it is always in a profound sleep, nor can +we say that it is insensible to its surroundings. Touch it gently or +surprise it with a puff of air from your mouth, and it will begin to +wag its pointed tail, sometimes with such vigour as to send the +body rolling round and round in its box. Lay it on a bed of cocoa-nut<!-- Page 49 --><span class="pagenum"><a name="Page_49" id="Page_49">[Pg 49]</a></span> +fibre or finely sifted soil and let it remain <i>quite undisturbed</i> for +a few hours or days, and you will probably find that, by occasional +movements of its body, it has made a slight depression in its bed, +and lies partly submerged. I have known some chrysalides to +completely bury themselves in this way during the course of a day +or two, and others to partly expose themselves after having been +lightly covered. Others again, I have observed, will move smartly +if a strong light is suddenly turned on them. Many, too, certainly +appear to have a strong objection to exposure to the direct rays +of a hot sun; for, when thus exposed, they will struggle persistently, +as if to work their bodies into some shady corner. I +would not advise a young entomologist to try this experiment, +however, if he values the pupæ he possesses, for direct sunlight +is undoubtedly very harmful to many species, and perhaps it is +to all.</p> + +<p>Some chrysalides are not nearly so active as has just been +represented; in fact, there are many which seem to show no signs +of life during the greater part of the time spent in that state. But +in all, whether apparently active or not, certain important internal +changes are at work. We have already noticed that, even in the +last days of the <i>larval</i> existence, some of the organs of the future +imago are to be traced. But these are as yet imperfectly developed. +We have also observed that a continuation of these changes, +gradually carried on, would be impossible in a voracious feeder; so +the insect, now fully grown, and no longer requiring a supply of +food, settles down in perfect quiet, submitting itself quite passively +to any further changes that nature may demand.</p> + +<p>It has already suffered the loss of its claspers. Its wonderful +jaws that did so much damage (for good or evil as the case may be) +to the vegetable world are now gone, and the bulky digestive +apparatus has rapidly dwindled to useless dimensions. These and +other changes, already in progress, have to be perfected while the +creature is in a restful and helpless condition, though they may +often be retarded or even suspended during cold weather when +progress would certainly bring it to an untimely end.</p> + +<p>But now the grandest of all these transformation scenes is +nigh at hand. The protective skin is already loosening from the +almost perfect imago, and consequently feels softer and far more +yielding than it did when in close contact with the body: the +swaddled butterfly or moth (for such the pupa is) is slowly preparing +to throw off its imprisoning garb. The wings and large<!-- Page 50 --><span class="pagenum"><a name="Page_50" id="Page_50">[Pg 50]</a></span> +compound eyes are assuming their final colours, which now begin +to show themselves through the more or less transparent skin, +and the long legs, the perfectly formed antennæ, and the slender +proboscis, all of which are folded closely under the creature's thorax, +now begin to move within their loosened sheaths.</p> + +<p>Now let us watch it closely, for one of the most wonderful sights +ever witnessed by a naturalist is about to be presented to our view. +We think we can observe slight movements; and, it may be, we can +actually see the struggling insect endeavouring to set itself free. The +legs and proboscis are moving within the loosened skin; and lo! as +we watch these motions, the prison wall bursts with a slight snapping +noise (at least, such is the case with some of the larger species), +and in a moment out pop a few long legs which immediately +struggle for a foothold. The proboscis also appears, alternately +lengthening itself out and coiling into a spiral, as if impatient to +reach the sweet nectar from the bottom of +some fragrant flower cup.</p> + +<div class="figleft" style="width: 300px;"> +<a name="FIG_36" id="FIG_36"></a><img src="images/i_067.jpg" width="300" height="224" alt="" title="" /> +<span class="caption">Fig. 36—A Butterfly, +just after +Emerging.</span> +</div> + +<p>All this takes place in less time than one +requires to describe it; and, before many +seconds have passed, the struggling insect +has quite completed its last moult, and is +bidding good-bye to the rent garment that +has done it good service for so long a time.</p> + +<p>But how dreadfully disappointing! Did +we not say only a few minutes since, that a +beautiful butterfly or moth was about to emerge? How, then, is +this? Here is an odd-looking creature, such as we have never seen +before! True, it has the right kind of body, though even that is so +soft and heavy that it is fairly dragged along as the insect walks. +Its antennæ, too, seem to be just the right thing—that is, just +what we were expecting to see. But oh! the wings! Are we +looking at a deformity?—a failure on the part of Nature to produce +what she ought?</p> + +<p>We will not judge hastily, but continue to watch it a little +longer. It seems very restless at first, and, with the fluttering +apologies for wings, drags its heavy body along till it reaches some +surface up which it can climb. If nothing of the kind is close at +hand you may place a <i>rough</i> upright stick in its path, and it +will immediately begin to ascend. Its motto is now 'Excelsior!' +and its ambition to rise may be so great that, on reaching the very +top of the stick provided for it, it struggles for a still higher position<!-- Page 51 --><span class="pagenum"><a name="Page_51" id="Page_51">[Pg 51]</a></span> +in life till, failing to get a foothold in the air itself, it falls to the +ground and has to retrace its steps.</p> + +<p>I once thought I would like to test the perseverance of a large +moth in performing its first upward journey; and as it was one +from a chrysalis to be found in nature at the foot of a tree that +attains some considerable height, I was, of course, prepared to +exercise a little patience myself.</p> + +<p>As soon as the moth had emerged, I placed it at the bottom of +a window curtain that hung from about eight feet high to the +floor. In less than half a minute it had reached the top, and was +struggling hard to get still higher. I took it down, and again +placed it at the bottom. Up it went as fast as before; and this +was repeated nine times with exactly the same result. For the +tenth time I placed the persevering creature at the bottom of +the curtain; and, after it had walked about halfway up, it <i>suddenly</i> +stopped, apparently quite satisfied with having travelled a distance +of over seventy feet in an upward direction. Its six legs were +immediately arranged symmetrically in a business-like manner, +and there it settled quite still, as if it had some definite object in +stopping just exactly in that spot.</p> + +<p>But we must now return to our own insect, which has by this +time settled itself in a similar manner on the stick we provided +for it. The peculiar organs which represent the wings, though so +very small, show distinctly, in miniature, the colour and pattern of +the fully developed wings of the species. An interesting change is +just now commencing. These wings are apparently growing larger, +but the development is very unequal, so that they become curled and +crumpled till they are even more unsightly than before. All seems +to be going amiss. But this lasts only for a short time. The +fluid from the body steadily rushes into the <i>nervures</i>, causing the +wings to expand, and in a few minutes the beautiful pinions are +stretched to the full extent, assume their normal shape, and expose +the full glory of their brilliant colours.</p> + +<p>It may be interesting if I give an example showing the exact +time taken for the full development of the wings of a certain +insect. So I will here quote an entry from my note book; and, by +the way, let me strongly advise all my young readers who follow +up this subject to habitually enter in a book kept specially for the +purpose all facts which strike them as they pursue their study of +nature. The note to which I refer runs as follows:</p> + +<p>'Early on the evening of the 22nd [April] I selected a few<!-- Page 52 --><span class="pagenum"><a name="Page_52" id="Page_52">[Pg 52]</a></span> +chrysalides of Populi [the Poplar Hawk Moth, <a href="#Page_209">page 209</a>] which, +from the looseness of their cases, were thought to be just on the +point of emerging. At 8.46 one of them showed signs of restlessness; +and, after a few vigorous movements, during which it rolled +itself over on the glass [I had placed the pupæ on a piece of plate +glass so that slight movements might be more easily detected], the +front of its case was suddenly thrust off with considerable force; +and in <i>less than four seconds</i> the imago was quite free and +crawling on the table. After trying hard to reach a higher point +than was provided for about four minutes, it rested to expand its +wings—now about seven-sixteenths of an inch long, or one-third +the total length of the body. At 9 o'clock the wings reached +half the length of the body, and were much curled. At 9.12 they +were fully expanded and straightened out.'</p> + +<p>From this extract we see that the whole period from the +bursting of the case to the full expansion of the wings was only +twenty-six minutes; and it will be well to remind the reader that +the process occupies even a much shorter time than this with +many species, both of butterflies and moths. It will be observed, +also, that the <i>evening</i> was chosen as the time for the observation. +There was a reason for this. The Poplar Hawk Moth, as is the case +with many others, almost invariably emerges from the chrysalis in +the evening—usually after dark. But it may be mentioned in +passing that a far larger number of the <i>Lepidoptera</i> as invariably +emerge in the morning.</p> + +<p>Again we will return to our newly emerged insect, for there are +still one or two interesting points to observe. The wings have +fully expanded, it is true, but how very limp they are! Take the +creature on the tip of your finger and hold it so that its body is +in a horizontal position. Immediately the wings bend downward +with their own weight, so soft and flexible are they. The body, too, +is still very soft, and apparently much too heavy for flight. Then, +if you place it on a flat surface, it will immediately try to find +some perpendicular or overhanging surface from which it can +suspend itself by means of its legs, so that the pendant and +straightened wings are in the best possible position for drying. As +the insect walks away in search of such a resting place, the body +still drags as it did before, and the wings bend over, either both on +one side or one on each side of the body.</p> + +<p>It is some time before the wings are sufficiently dry and rigid +for flight, but the period varies greatly with different species.<!-- Page 53 --><span class="pagenum"><a name="Page_53" id="Page_53">[Pg 53]</a></span> +Some of the small butterflies and moths take to flight long before +an hour has passed, but in many cases several hours elapse before +the creature starts from its first resting place. Butterflies that +emerge in the morning spend their first day actively on the wing; +but the nocturnal moths that emerge early in the day do not fly till +evening twilight. When, however, the time arrives, the insect +flutters its wings as if to test their power before committing itself +to the air; and frequently, after only a few seconds spent in this +preparatory exercise, off it darts with astonishing rapidity. But +others seem far more cautious. They vibrate their wings, sometimes +with such rapidity that they are lost in a kind of mist, and +with such power that their bodies would be carried suddenly into +the air were they not firmly anchored by three pairs of hooked +claws. Then, continuing the rapid vibration, they move slowly +along, always holding on firmly by one or more legs, as if to still +further satisfy themselves concerning the efficiency of their wings. +Then they venture on a few short trial trips from one neighbouring +object to another, and at last gain sufficient confidence for a long +voyage.</p> + +<p>How strange must be the feelings of a winged insect during its +first flight! After a long period during which it was a helpless, +crawling grub, and this followed by a term of imprisonment during +which it was almost or quite shut off from the world, it now suddenly +acquires such great powers of locomotion that it is often a +match for ourselves.</p> + +<p>But, alas! this life is short. A few days spent in sporting with +those it meets and in sucking the sweet juices of many flowers; +then a day or two during which the female deposits its eggs; again +a few days employed in pleasures that become less and less attractive, +till, at last, the creature becomes weary of life and settles +down to die.</p> + +<p>We have now traced the complete life history of the <i>Lepidoptera</i> +from the egg to the perfect insect, avoiding descriptions that +apply only to certain species as far as possible, excepting where +such are useful as illustrations.</p> + +<p>Only one thing more remains to be done before we start in real +earnest with our practical work. We shall shortly be giving hints +on the modes of capture, the 'setting' and the preservation of +butterflies and moths. And in so doing we shall often have to +observe important points in which our dealings with these two +great divisions of the order will differ very materially. Hence we<!-- Page 54 --><span class="pagenum"><a name="Page_54" id="Page_54">[Pg 54]</a></span> +must not consider ourselves ready to proceed with the practical +portion of the entomologist's labours till we are perfectly satisfied +that we know the main features that enable us to distinguish +between the butterflies and the moths, and also know just a little +concerning the subdivisions on each side.</p> + +<p>This, then, shall form the subject of the next short chapter.</p> + + + +<hr /> +<p><!-- Page 55 --><span class="pagenum"><a name="Page_55" id="Page_55">[Pg 55]</a></span></p> +<h3>CHAPTER V +<br /> +<i>CLASSIFICATION OF THE LEPIDOPTERA</i></h3> + + +<p>The <i>Lepidoptera</i> are divided into two very unequal groups, to +which we have so frequently alluded as 'Butterflies' and 'Moths.' +And, although these two terms are popularly applied in a fairly +accurate manner, yet, strange to say, very few persons indeed have +any definite knowledge of the differences that entomologists recognise +between the two groups.</p> + +<p>Every entomologist has his circle of sympathetic and, perhaps, +even admiring friends. Consequently, many a little package is +sent round to his abode 'with great care,' accompanied by a note +or a message concerning the fine 'butterfly I have just caught, and +thought you would like to add to your collection.'</p> + +<p>The 'butterflies' that so frequently reach us through these +channels nearly always turn out to be <i>brightly coloured</i> moths, +and this naturally gives one the idea that the popular notion as to +the classification of the <i>Lepidoptera</i> is based on colour or brilliancy +of design, the term 'butterfly' being applied to the gayer species, +and 'moth' to the more dingy members of the race.</p> + +<p>There is really some shadow of a reason in this method of +nomenclature, for butterflies <i>are usually</i> more brightly clad than +moths; but the scientific classification, at least as far as the main +divisions and subdivisions are concerned, has nothing whatever to +do with colour or design; and we must at once acquaint ourselves +with the fact that there <i>are</i> very dingy butterflies, and most +beautiful and highly coloured moths.</p> + +<p>How shall we account for the fact that the specimens so kindly +sent us by our friends are generally moths? Is it because moths +are more numerous and more frequently seen? They are certainly +more numerous; for, while our butterflies do not number seventy<!-- Page 56 --><span class="pagenum"><a name="Page_56" id="Page_56">[Pg 56]</a></span> +species, the other division contains about two thousand. Yet, in +spite of this fact, moths are not generally observed as much as +butterflies, for the former are nearly all night-fliers, and the latter +<i>always</i> fly by day and rest by night.</p> + +<p>Still our question remains unanswered. The reason is this. +The captives sent us are seldom caught on the wing. Most of our +grown-up friends, even though they admire our own pluck and +general carelessness concerning the remarks of the spectators of +our entomological antics, would not themselves like to be seen, hat +in hand, chasing a butterfly; and the night-flying moths are, of +course, less frequently observed. But they often, in the course of +their daily employments, meet with a large moth fast asleep +in some corner of a dwelling house, workshop, or outhouse. Such +moths are easily caught while in the midst of their slumbers, +and, as they often make no attempt to fly by day, are as easily +transferred to a box suitable for transmission by messenger or by +post.</p> + +<p>In the above few remarks we have alluded to some features by +which the two great groups of the <i>Lepidoptera</i> may be distinguished; +but we have already referred (<a href="#Page_5">page 5</a>) to a far more +important one in our description of the various forms of antennæ. +All butterflies—at least all <i>British</i> butterflies—have knobbed or +clubbed antennæ, while the corresponding organs of all our moths +terminate in a sharp point.</p> + +<p>This distinction obtains in all British <i>Lepidoptera</i>, and is so far +regarded as the most important basis of classification that naturalists +have derived from it the two Greek terms that are synonymous +with our two popular names—butterflies and moths. The scientific +name for the former group is <i>Rhopalocera</i>—a term derived from +two Greek words, one signifying a horn, and the other a club, and +thus meaning 'club-horned.' The corresponding name for moths +is <i>Heterocera</i>, derived from the same source, and meaning 'variously +horned.'</p> + +<p>But, although we find embodied in these two long and formidable +names an unerring mark of distinction between British +butterflies and moths, we must not neglect other less important +facts which, though less distinctive, are not without interest.</p> + +<p>Observe a butterfly at rest. Its wings are turned vertically +over its back, and brought so closely together that they often +touch. In this position the 'upper' surfaces of the 'upper' wings +are completely hidden from view, and the 'under' surfaces are<!-- Page 57 --><span class="pagenum"><a name="Page_57" id="Page_57">[Pg 57]</a></span> +exposed on the two sides, except that those of the 'upper' pair are +partly hidden by the other pair.</p> + +<p>Now look at a moth under the same circumstances, and you +will generally find the wings lying over its body, which is almost or +completely hidden beneath them. As a rule the upper pair together +form a triangular figure, and entirely cover the second pair; but +in some cases a portion of each of the under wings extends beyond +the margin of those above them, and in others the upper pair +extend so far forward that nearly the whole of the under wings is +exposed behind them.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_37" id="FIG_37"></a><img src="images/i_074a.jpg" width="300" height="352" alt="" title="" /> +<span class="caption">Fig. 37.—A Butterfly at Rest +(Large Copper).</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_38" id="FIG_38"></a><img src="images/i_074b.jpg" width="300" height="366" alt="" title="" /> +<span class="caption">Fig. 38.—A Moth at Rest +(Gothic).</span> +</div> + +<p>Again, the wings of butterflies are so rigid that they can never +be folded; but you will observe that the under wings of moths are +generally very thin, soft, and pliant, +and are neatly pleated lengthwise when +not in use.</p> + +<p>Another feature deserving notice is +a slight difference to be often observed in the form of the body. +The butterfly, which generally has a slender body, has a distinct +constriction or waist between the thorax and abdomen. This is +not so apparent with moths, and especially with the thick-bodied +species.</p> + +<p>The <i>Rhopalocera</i> or Butterflies are divided into <i>Families</i>, each +of which contains insects that possess certain features in common +by which they may all be distinguished from the members of any +other family.</p> + +<p>The British species represent eight families. They are as +follows:</p> + +<p>1. <i>Papilionidæ.</i>—Containing only one British species—the +beautiful Swallow-tail (<a href="#Frontispiece">Plate I</a>, fig. 1).<!-- Page 58 --><span class="pagenum"><a name="Page_58" id="Page_58">[Pg 58]</a></span></p> + +<p>2. <i>Pieridæ.</i>—Containing ten species. These are often known +collectively as the 'Whites,' but include four butterflies that are +distinguished by beautiful shades of yellow and orange.</p> + +<p>3. <i>Nymphalidæ.</i>—This family contains seventeen insects, +among them being several splendid species. It includes the +Fritillaries and Vanessas.</p> + +<p>4. <i>Apaturidæ.</i>—Of this we have only one representative—the +Purple Emperor (<a href="#Plate_V">Plate V</a>, fig. 1).</p> + +<p>5. <i>Satyridæ.</i>—Including the 'Browns' and 'Heaths,' and +numbering eleven species.</p> + +<p>6. <i>Lycænidæ.</i>—Including the Hairstreaks, 'Coppers,' and +'Blues,' in all seventeen species.</p> + +<p>7. <i>Erycinidæ.</i>—Containing only the 'Duke of Burgundy.'</p> + +<p>8. <i>Hesperiidæ.</i>—This family contains seven British butterflies +commonly known as the 'Skippers.'</p> + +<p>Although all the members of the same family resemble each other +in certain points of structure, or in their habits, yet we can often find +among them a smaller group differing from all the others in one or +two minor particulars. Such smaller groups are called <i>Genera</i>.</p> + +<p>To make this all quite clear we will take an example.</p> + +<p>The Brimstone Butterfly (<a href="#Plate_II">Plate II</a>, fig. 4) belongs to the second +family—<i>Pieridæ</i>, <i>all</i> the members of which are distinguished +from those of the other families by the characteristics mentioned +on <a href="#Page_141">page 141</a>.</p> + +<p>But our Brimstone Butterfly possesses another very prominent +feature in which it differs from all the other British <i>Pieridæ</i>, and +that is the conspicuous projecting angles of both fore and hind +wings. Among the foreign species of the family we are considering +there are several that possess these angles; but as there are no +others among our own members, the 'Brimstone' is placed by +itself in the list of British <i>Lepidoptera</i> as the only member of the +genus <i>Gonopteryx</i> or 'angle-winged' butterflies.</p> + +<p>Thus the full relationship of this butterfly to other insects may +be shown in the following manner:</p> + + +<p><i>The Brimstone Butterfly.</i></p> +<ul> +<li><b>ORDER.</b>—<i>Lepidoptera</i></li> +<li><b>Section.</b>—<i>Rhopalocera</i></li> +<li><span class="smcap">Family.</span>—<i>Pieridæ</i></li> +<li><i>Genus.</i>—<i>Gonopteryx</i></li> +<li>Species.—<i>Rhamni</i></li> +</ul> +<p><!-- Page 59 --><span class="pagenum"><a name="Page_59" id="Page_59">[Pg 59]</a></span></p> + +<p>Now, every butterfly has a Latin or Greek name in addition to +that by which it is popularly known. I should have said <i>two</i> Latin +or Greek names. The first of these is always the <i>generic</i> name, +and the second is the one by which we denote the particular +member or <i>species</i> of that genus. Thus, the scientific name of the +Brimstone Butterfly is <i>Gonopteryx Rhamni</i>.</p> + +<p>'But,' the reader may be inclined to ask, 'why should we not +be satisfied with the one popular name only?' And, 'If we <i>must</i> +have a separate scientific name, could we not find suitable terms +among our English words to build up such a name—one that +might express the principal characteristics of the insect, and also +serve all the purposes of classification?'</p> + +<p>Such questions sound very reasonable, and so they are. But +the entomologist's answer is this. We ourselves may get on well +without the help of the dead languages, but we have brother +naturalists all over the world, speaking a great variety of different +languages. We endeavour to help one another—to exchange notes +and generally to assist one another in our labours; and this can be +greatly facilitated if we all adopt the same system of nomenclature. +The educated of most of the great nations generally know something +of Latin and Greek, and consequently the adoption of these +languages is generally acceptable to all.</p> + +<p>This sounds well, but for my own part I believe that if we are +to make any branch of natural history a popular study, especially +with the young, we must to a certain extent avoid anything that +may prove distasteful. There is no doubt whatever that many a +youngster has been turned away from the pursuit of the study of +nature by the formidable array of almost unpronounceable names +that stretch nearly halfway across a page; and those who desire +to make such a study pleasant to beginners should be very cautious +with the use of these necessary evils. One would think, on glancing +over some of the scientific manuals that are written 'especially +for the young,' that the authors considered our own too mean a +language for so exalted a purpose, for in such works we find all or +nearly all the popular names by which the schoolboy knows certain +creatures he has seen entirely omitted, and the description of a +species appended to a long Latin term that conveys no idea whatever +to the reader, who is studying the description of a well-known +animal or plant and doesn't know it.</p> + +<p>Our plan will be to give the popular names throughout, except +in the case of those few species that are not so well known as to<!-- Page 60 --><span class="pagenum"><a name="Page_60" id="Page_60">[Pg 60]</a></span> +have received one; but the scientific names will always be given +as well for the benefit of those readers who would like to know +them. And the short description of the method of classification +just given will enable the more ambitious of my readers to thoroughly +understand the table of British butterflies and moths +toward the end of the book.</p> + +<p>This table includes <i>all</i> the British species of butterflies and of +the larger moths; and the arrangement is such as to show clearly +the divisions into sections, families, &c. It will therefore be of +great value for reference, and as a guide for the arrangement of +the specimens in the cabinet.</p> + +<p>In the foregoing description of the method of classification +butterflies only are mentioned; but the division and arrangement +of moths is carried out in just the same manner except that the +system is a little more complicated. The number of moths is so +large in comparison, that we are able to select from them some +very large groups the species of which possess features in common. +These groups are termed <i>tribes</i>, and are again divided into families +just like the butterflies. Thus the arrangement of moths includes +<i>tribes</i>, <i>families</i>, <i>genera</i> and <i>species</i>. We will take an example by +way of illustration as we did before, and ask the reader to verify +the same by comparison with our table:</p> + +<p><i>Example.</i>—The 'Common Tiger' (<a href="#Plate_X">Plate X</a>, fig. 3).</p> + +<ul> +<li><b>ORDER.</b>—<i>Lepidoptera</i></li> +<li><b>Section.</b>—<i>Heterocera</i></li> +<li>TRIBE.—<i>Bombyces</i></li> +<li><span class="smcap">Family.</span>—<i>Cheloniidæ</i></li> +<li><i>Genus.</i>—<i>Arctia</i></li> +<li>Species.—<i>Caia</i></li> +<li>Scientific Name.—<i>Arctia Caia.</i></li> +</ul> + +<p>I have already said that the Latin and Greek names of butterflies +and moths are not at all necessary to the young entomologist. +It is quite possible to be well acquainted with the natural history +of these creatures, and to derive all the pleasure and benefits that +the study of them can afford without the knowledge of such names; +but most entomologists go in for them, often to the entire exclusion +of the popular English terms.</p> + +<p>There are those who consider themselves (or would have us +consider them) expert entomologists because they have the power<!-- Page 61 --><span class="pagenum"><a name="Page_61" id="Page_61">[Pg 61]</a></span> +to vomit forth a long list of scientific names of butterflies and +moths which (to them) have no meaning whatever; and it is astonishing +that we meet with so many youngsters who can rattle +away such terms, and, at the same time, are totally ignorant of +the real nature of the creatures they name.</p> + +<p>If you wish to be a naturalist in the true sense of the term, study +your <i>specimens</i>, and take but little pains to commit their hard +names to memory; and you will then find that the latter will +gradually become your own property without any special effort on +your part. Your continued reference to illustrated works and +museum collections will bring them to you almost unconsciously, +and you will generally find your entomological vocabulary extending +as rapidly as your cabinet becomes filled.</p> + +<p>Again, with regard to the <i>meanings</i> of the scientific terms, don't +trouble much about them. It unfortunately happens that in a very +large number of cases these names are ill chosen, and do not in any +way refer to the distinguishing characteristics of the species to +which they are applied. You will observe, too, if you look at the +table, that many insects have <i>two</i> scientific names applied to the +species, one being placed in brackets after the other. In such +cases both these names are in common use, having both been +applied by independent authorities, and the insertion of the +two will prove an assistance at times.</p> + +<p>It is a common practice with entomologists, in their communications, +to use only the second or <i>specific</i> name of insects. Thus, +they would speak of the Brimstone Butterfly as <i>Rhamni</i>, and not +<i>Gonopteryx Rhamni</i>. When <i>writing</i> a communication, however, +they very commonly place in front of the specific name the initial +letter of the first or <i>generic</i> name. Thus the full title of the +butterfly just mentioned would be abbreviated to <i>G. Rhamni</i>.</p> + +<p>Having said so much concerning the principles of classification +and nomenclature, we will pass on to the practical portion of the +entomologist's work.<!-- Page 62 --><span class="pagenum"><a name="Page_62" id="Page_62">[Pg 62]</a></span></p> + + + +<hr class="long" /> +<p><!-- Page 63 --><span class="pagenum"><a name="Page_63" id="Page_63">[Pg 63]</a></span></p> +<h2>PART II<br /> +<br /> +WORK AT HOME AND IN THE FIELD</h2> + + + +<hr /> +<h3>CHAPTER VI +<br /> +<i>CATCHING BUTTERFLIES AND MOTHS</i></h3> + + +<p>It is not at all surprising that entomology should prove such a +fascinating study to the young, and more especially that portion +which deals with the department we are now considering. Butterflies +and moths are among the most beautiful and most interesting +of living creatures. The study of their life history is enchanting, +and the creatures themselves are of such a size as to be conveniently +handled and preserved, and withal occupy so little space +that anyone with only moderate accommodation may possess a +fairly typical collection.</p> + +<p>Compare the work of the entomologist with that of one whose +hobby is the study of mammals. The latter has to deal with large +and cumbersome objects, a collection of which requires an enormous +amount of space; and, unless he has the time and means to +travel in foreign countries, he cannot get together a good typical +collection of specimens representing his particular branch, for the +few British mammals contain no representatives of several of the +orders into which the class is divided.</p> + +<p>Entomology is undoubtedly, <i>par excellence</i>, <i>the</i> study for +youngsters. It is equally suited to the studious and to those of an +adventurous turn of mind. It leads its follower into the bright sunshine +and the flowery meadows; and with body and mind pleasantly +occupied, the joy of living is deeply felt. The necessary apparatus +can be made by anyone. No dangerous gun is required, and there +are no precipitous rocks to scale. When the autumn flowers fade +the year's work of the entomologist is not done, for the arranging<!-- Page 64 --><span class="pagenum"><a name="Page_64" id="Page_64">[Pg 64]</a></span> +of his cabinet and the demands of his living specimens keep him +more or less actively engaged until the flowers of the following +spring call both him and the insects he loves once more into the +field. And so, season after season, and year after year, he finds +himself engrossed in labours so fascinating that idleness—the curse +of so many of our youths—is with him an impossibility.</p> + +<p>I assume that the readers of this book have a desire to take up +the study of one branch of entomology—that of butterflies and +moths—in real earnest; that they intend not only to <i>read</i> about +these interesting insects, but to <i>know</i> them. And there is only one +way in which one may really get to know living creatures; that +is by searching them out in their haunts, observing their growth +and habits, and by an occasional close examination in order to +become acquainted with their structure.</p> + +<p>Hence I shall in this, the practical portion of the work, give +such information as will assist the beginner in catching, preserving, +rearing, breeding, and arranging the specimens that are to form his +collection.</p> + + +<h4><i>Catching Butterflies</i></h4> + +<p>There was a time when we would try to capture a butterfly at +rest on a flower by a quick sweep of the hand, or, more commonly, +by a sharp downward stroke of the cap. We were led to this action +by a mere childish love of sport, or by a desire to possess an insect +simply because it was pretty. When we succeeded in securing our +prize, we handled it somewhat carelessly, often passing it from one +hand to the other, or boxing it in our closed and perspiring fist till +our fingers were dusted with the pretty microscopic scales of the +creature's wings, and the wings themselves, stripped of all their +beautiful clothing, were merely transparent and veined membranes. +Having thus carelessly but unintentionally deprived the creature of +its greatest beauty, we set it free, often in such a damaged or +exhausted condition that the poor thing could scarcely fly.</p> + +<p>But our childish ideas and inclinations have vanished. Now +we would rather watch the insect than catch it, for we find much +pleasure and interest in its varied movements. And if for purposes +of study we occasionally require to make one captive, we proceed +in such a manner as to preserve its beauty unimpaired. The cap +now gives place to a well-made and suitable net; and we are +careful to provide ourselves with sufficient and proper accommodation +for our captives.<!-- Page 65 --><span class="pagenum"><a name="Page_65" id="Page_65">[Pg 65]</a></span></p> + +<p>It is probable that many of my readers are as yet unacquainted +with the nature of an entomologist's requirements for field work, +so we shall describe them, confining ourselves at first to those that +are required for a butterfly hunt.</p> + +<p>First and foremost comes the net. This essential portion of your +equipment may be either purchased or constructed by yourself. +Very little skill is required to enable you to do the former. Provided +your pocket is well charged, you may start off at once to the +dealer in naturalists' appliances, and treat yourself to a complete +outfit. But even in this case a little advice may not be out of +place. See that what you purchase is very <i>strongly</i> made. You can +get nicely finished nets constructed on the most convenient principles, +made to fold and go in an ordinary coat pocket, but with +<i>weak joints</i>. See that you have the most convenient form of net +by all means, but do not +go in for convenience and +appearance at the expense +of strength and durability. +Nothing is more annoying +than to find your net give +way just when you are in +the midst of a good day's +sport.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_39" id="FIG_39"></a><img src="images/i_082a.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 39.—A Wire Frame +for a Butterfly Net.</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_40" id="FIG_40"></a><img src="images/i_082b.jpg" width="300" height="221" alt="" title="" /> +<span class="caption">Fig. 40.</span> +</div> + +<p>The folding net is certainly +very convenient, for +you can conceal it in your +pocket while you are walking +through town or travelling in a railway carriage, and thus avoid +that contemptuous gaze which certain of the public are prone to +cast on a poor 'bug hunter.' And although such nets are generally +purchased, yet they <i>may</i> be constructed by anyone who has had +experience in the working of metals. But other forms of nets, +equally useful and even stronger, can be made by anybody; and I +will give a few hints on two or three different ways of putting +them together.</p> + +<p>A very simple and strong frame for a net may be made as +follows: Get a piece of stout iron or brass wire about forty inches +in length, and bend it into a circle with the two ends, turned out +about two inches each, at right angles to the circumference as +shown in the accompanying sketch.</p> + +<p>Now take a good tough stick, the length of an ordinary walking<!-- Page 66 --><span class="pagenum"><a name="Page_66" id="Page_66">[Pg 66]</a></span> +stick, and cut out two grooves opposite each other at the end, just +large enough to take the straight ends of the wire. The end of the +stick will now resemble fig. 40 in shape. Place the ends in their +grooves, and bind them tightly to the stick by a good many turns +of rather fine wire.</p> + +<p>A frame well made after this fashion is as strong as anything +you could desire, but it has the disadvantage of being always fixed +to the handle, thus preventing the use of the latter as a walking +stick when you are not directly engaged in your entomological +work.</p> + +<p>A much more convenient frame may be made by thrusting the +ends of a piece of cane into the two narrow arms of a metal <span class="lettershape">Y</span>. +You may purchase the <span class="lettershape">Y</span> at any of the naturalists' stores, or you +can make one yourself if you know how to perform the operation of +soldering. I have always made mine with odds and ends of brass +tubing such as old gas pipes. One piece must be just the size to +fix on the stick; and the other two must fit the cane +tightly. The three pieces must be filed off at the +proper angles, and the doubly bevelled end of the +wider tube must then be flattened down to the +width of the smaller ones before soldering. If you +decide to buy one, give the preference to strong +brass rather than the cheaper and more fragile ones +made of tinned iron.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_41" id="FIG_41"></a><img src="images/i_083.jpg" width="300" height="275" alt="" title="" /> +<span class="caption">Fig. 41. +The Metal <span class="lettershape">Y</span>.</span> +</div> + +<p>The advantage of such an arrangement over the +last frame is evident at once. The cane, with net attached, can +be pulled out of the <span class="lettershape">Y</span> when not in use, and bent small enough to +go in the pocket or a satchel; and the <span class="lettershape">Y</span> can also be separated +from the stick, thus allowing the latter to be used as a walking +stick.</p> + +<p>Some entomologists speak very favourably of what is known +as the 'umbrella net'—a large and light net that will shut up like +an umbrella, and may even be made to look very much like this +useful protector, but the possession of such an imitation is somewhat +tantalising in a pelting shower. The ring of this net consists +of two steel springs attached to a couple of brass hinges, one of +which is fixed near one end of the handle, while the other slides up +and down in the gamp fashion.</p> + +<p>One other form of net—'the clap net'—although still occasionally +seen, has had its best days. Two sticks are provided to this +one, so that the two sides of the net may be brought together on<!-- Page 67 --><span class="pagenum"><a name="Page_67" id="Page_67">[Pg 67]</a></span> +the insect; but as both hands are required to manage it, it is almost +surprising that it ever had any advocates at all.</p> + +<p>When your frame is completed, sew round it a strip of strong +calico, to which the net itself may be afterwards sewn, for the lighter +material of the net is too delicate to stand the constant friction +against the metal or cane frame.</p> + +<p>The material usually employed in making the 'bag' is called +leno. It can be purchased at most of the drapers' shops, and three +colours—white, yellow and green—are usually kept in stock. +Measure the circumference of your net frame, and see that you get +sufficient leno to make a good full net. Suppose, for instance, that +the circle of your frame measures thirty-six inches round, then your +leno should be at least forty inches in length. Fold this double, +and then cut out two pieces of the shape shown in fig. 42, letting +the depth of the net be nearly or quite equal to the width of the +material. There is nothing to be done now but to +stitch the bag together and sew it to the calico on +the ring.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_42" id="FIG_42"></a><img src="images/i_084.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 42.</span> +</div> + +<p>At first you will find the leno rather stiff and +harsh, but a damping and good rubbing between +the hands will soften it down; or, if you prefer it, +you may soften the material by a slight washing +before cutting out the net. The latter is perhaps +the better plan, for the washing will remove the +objectionable 'dressing' that renders the material +rather hard and stiff.</p> + +<p>Of the three colours mentioned above, green is the one most +generally chosen, because it is more in harmony with the surroundings +of a butterfly catcher; but many prefer the white leno +to the green, as the insects are more easily seen in a net of this +colour. Yellow is certainly not a desirable tint.</p> + +<p>As a rule it will be necessary to kill an insect as soon as it is +captured. This is always the case with butterflies unless you +require to keep them alive either to watch their movements or to +obtain eggs. For this purpose you will require a killing bottle or +box containing some volatile substance.</p> + +<p>The selection of this necessary piece of apparatus is a point +deserving of much consideration, for so many different forms are in +use by different entomologists, and so many advocates each declare +that his own plan is far superior to that of any of the others, that +the final decision is not to be worked out in a moment. The best<!-- Page 68 --><span class="pagenum"><a name="Page_68" id="Page_68">[Pg 68]</a></span> +thing for a beginner is to try as many as he can, and then, after +some considerable experience of his own, he will be able to decide +which apparatus suits himself best.</p> + +<p>I recommend this because it is impossible to say of any one +plan that it is the best, for that which gives perfect satisfaction to +one individual will often fail to give anything but annoyance in +the hands of another.</p> + +<p>To enable my young readers to follow the advice I have just +given, I will describe some of the commonly used killing arrangements +and show how they should be used.</p> + +<p>I will take first the 'cyanide bottle.' This is a wide-mouthed +bottle, containing a very poisonous substance called <i>cyanide of +potassium</i>. It is fitted with a good sound +cork. The 'cyanide' is a solid substance, and +must be fixed in some way or other at the +bottom of the bottle so that it cannot shake +about and damage the butterflies.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_43" id="FIG_43"></a><img src="images/i_085.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 43.—The Cyanide +Bottle.</span> +</div> + +<p>A cyanide bottle can be purchased ready +for use at the cost of a shilling or thereabouts; +but if you are old enough to be trusted with +deadly poisons, you may buy the 'cyanide' of +a chemist who knows you well and is satisfied +as to your intentions, and then prepare your +own. Every entomologist should know how +to do this, for the poison loses its power after +some time, and it is not always convenient to +leave your bottle in the hands of a chemist or +a 'naturalist' to have it recharged. This will +cost you more than it would to do it yourself, +but that is nothing compared with the annoyance that may result +when, the night before an anticipated butterfly hunt, you are calmly +told that 'your bottle will be ready in a few days.' You can charge it +yourself in a few minutes if you can manage to keep a small supply +of 'cyanide' in stock, and it is ready for use very shortly after.</p> + +<p>Here is the <i>modus operandi</i>.—Purchase an ounce or two of the +cyanide of potassium, and immediately put it into a stoppered or +well-corked bottle. Label it at once, not only with the name, +but also with the word <span class="smcap">Poison</span> in very large and conspicuous +letters. This dangerous chemical is often sold in sticks that look +much like certain 'sugar sticks' I was acquainted with in my +younger days; but whether this is or is not the case with your<!-- Page 69 --><span class="pagenum"><a name="Page_69" id="Page_69">[Pg 69]</a></span> +cyanide, see that the bottle is kept quite out of the reach of the +inquisitive and sugar-loving juveniles of the house.</p> + +<p>The quantity above mentioned is more than you will require for +the first 'charge,' but you will soon experience the convenience of +having a supply always at hand for recharging when your cyanide +bottle fails to do its work expeditiously, or when an accident calls +for the somewhat sudden appearance of a new one.</p> + +<p>Now procure a bottle for your work. Its mouth must be wide +enough to take the largest insect you hope to catch, and the widest +part of the bottle need not be much larger. Get a perfectly sound +cork to fit it tightly; and, to insure the more perfect exclusion of +air, paint over the top of the cork with melted paraffin wax.</p> + +<p>Dissolve a few drams of the cyanide in a little water, using a +glass rod to stir up the mixture till the solid has all disappeared; +and be careful that neither the solid nor the solution touches +the skin if it should be in the slightest degree scratched or +broken. Now sprinkle plaster of Paris into the solution, a little +at a time, and stir all the while. As soon as the mixture begins +to set, pour it into your bottle as cleanly as you can—that is, without +touching the sides—and press it down with the flat end of a +stick if it is not level. Now cork it, and put the bottle away in a +cool place till required for use.</p> + +<p>This is, I think, the best way of charging the bottle; but there +are two other common methods that may, perhaps, be regarded as a +little more simple. One is this: put a few small lumps of the +'cyanide' into your bottle, and then cover them with a stiff mixture +of plaster of Paris and water, and press down as before. The other +plan is to cover the 'cyanide' with a few thicknesses of blotting +paper, cut just a little larger than the inside of the bottle. The first +of these two methods is fairly satisfactory, but I have always found +that the charge, when made in this way, has a tendency to become +wet and pasty, in which condition it will spoil the wings of the +insects. The other is very objectionable, especially for field work, +for the blotting paper fails to keep its place while you are on the +chase. If the plaster is used, the mixing must be done quickly and +without hesitation, or the mixture will become solid before you can +press it into your bottle.</p> + +<p>We will not enter now into the <i>pros</i> and <i>cons</i> of the cyanide +bottle, but will consider the advantages and disadvantages of the +various methods of killing the insects after we have noticed a few +more.<!-- Page 70 --><span class="pagenum"><a name="Page_70" id="Page_70">[Pg 70]</a></span></p> + +<p>The 'laurel box' has had many devoted advocates, although it +does not seem to be much in use now. It is a very good arrangement, +however, but is a little more troublesome than the cyanide +bottle, as it requires frequent replenishing.</p> + +<p>A very good laurel box may be prepared as follows. Get a +small tin box of cylindrical form, measuring about five inches by +two, and cut a circle of perforated zinc or wood just the size to +fit it snugly as a false bottom without any danger of falling out of +its place. Now gather some of the young leaves of the green laurel +bush, and beat them almost to a pulp with a mallet or hammer. +Place this in your tin box, and press down the perforated false +bottom on it. The bruised laurel leaves give off +a very powerful odour, which stupefies butterflies +immediately.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_44" id="FIG_44"></a><img src="images/i_087.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 44.—Section +of the Laurel +Box.</span> +<p><i>a</i>, space for insects; +<i>b</i>, perforated partition; +<i>c</i>, bruised +laurel leaves.</p> +</div> + +<p>Of course the reader may be able to think +of various other ways in which the laurel box +may be made. Any arrangement will do providing +the vapour can come to the insects without +allowing the leaves to touch their wings; +and any ingenious youth could manufacture a +more satisfactory article than the one I have +mentioned. My desire is, as far as possible, to +give instructions that may easily be carried out +by anyone, even if he has not the slightest +mechanical skill, leaving the clever youth, sometimes, +the opportunity of displaying his own inventive +power. But in this case I will give a +few suggestions concerning other ways in which +a laurel killer may be constructed. A firm and <i>fixed</i> false bottom +is a decided advantage. This is easily managed by fixing a circular +piece of perforated zinc or 'tin' by means of a little solder; or even +a wood partition may be used, fixed with a few brads, driven into +it from the outside. With the fixed partition, however, you must +have a lid at each end of the box. This is easily managed if you +get two tins of the same size, knock out the bottom of one, and fit +the lid of the other in its place.</p> + +<p>I have heard of laurel boxes without any partition save a piece +of rag in which the bruised leaves are wrapped. The whole is +<i>pressed</i> into the box so firmly that it is not likely to be displaced +while you are on the chase. I do not recommend this, for in addition +to the chance of its slipping there is a danger of the sap of the<!-- Page 71 --><span class="pagenum"><a name="Page_71" id="Page_71">[Pg 71]</a></span> +leaves exuding through the rag and spoiling the insects' wings. +But if the reader should prefer to try this on account of its simplicity, +it will probably occur to him that a bottle may be used instead +of a tin box.</p> + +<p>A well-made laurel box, with a fixed metal partition, is a piece +of apparatus strongly to be recommended to all young entomologists +who desire to test the relative value of the various poisons +that are used by the different experts; for with it any one of these +substances can be used. In the poison compartment you can place +pieces of 'cyanide' wrapped in blotting paper, or any kind of +porous substance moistened with liquid ammonia, chloroform, +benzole, or any other volatile liquid insecticide. All the above-named +substances are declared to be 'the best,' so they must all +be worth the trial.</p> + +<p>'Cyanide' is valued on account of its lasting powers. A cyanide +bottle well charged will retain its efficiency throughout a whole +season. I always recharge two in the spring, one for active service +in the field and the other as a reserve force; and these kept in a +cool place do good execution throughout the year. If they should +exhibit a slight failing, a few minutes' warming before a fire will +improve them; but for field work it is better to recharge. At +the same time see that the corks are in good condition.</p> + +<p>Next to the 'cyanide,' the bruised laurel takes the first rank for +permanency; but you must not expect this to last many days. +For a few days' continuous work one charge will suffice, but if the +laurel box has not been in use for some time you must have a fresh +supply.</p> + +<p>The liquid poisons, such as ammonia, chloroform, and benzole, +are so volatile that they are very powerful for a short time, but so +much vapour is lost each time the box is opened that it is absolutely +necessary to carry a bottle of the one you use into the field with +you. Also see that you have sufficient of the blotting paper or +other absorbent to prevent the liquid from leaking through the +perforations of the partition.</p> + +<p>If you choose ammonia—a substance that is not regarded as a +poison, and is therefore easily obtained from any chemist—always +get the strongest, and see that it is labelled 'Liq. Ammonia, S.G. +·880' as a guarantee. A small bottle such as you can conveniently +carry in the waistcoat pocket will contain sufficient for a day's +work. Use only a few drops at a time, but renew frequently. +Although the ammonia corrodes cork, yet a good cork is far preferable<!-- Page 72 --><span class="pagenum"><a name="Page_72" id="Page_72">[Pg 72]</a></span> +for the pocket to a glass stopper, for its elasticity prevents +it from losing its hold, and the liquid from saturating your pocket +and its surroundings; but a glass stopper is certainly better for the +stock solution kept at home.</p> + +<p>Most of the above remarks apply equally well to benzole and to +chloroform, but the latter is so powerful a poison that a very little +is required for a day's work, and consequently a very small +bottle is more convenient. The dealers in naturalist's appliances +supply metal 'chloroform bottles' with screw stoppers and a small +nozzle that will allow the liquid to run out only in drops. This is +a very good arrangement, since it enables you to avoid the 'drop +too much' which is not only unnecessary and therefore wasteful, +but saves you from experiencing the disappointment +of an empty bottle before your work is half done.</p> + +<div class="figleft" style="width: 300px;"> +<a name="FIG_45" id="FIG_45"></a><img src="images/i_089.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 45.—The +Chloroform +Bottle.</span> +</div> + +<p>Some entomologists recommend the solid carbonate +of ammonium instead of liquid ammonia, but this is +not so powerful. It must be remembered that we +have the butterflies to consider, as well as our own +convenience, in the selection of the poisons we use. +It is the opinion of many well-known entomologists +that 'insects cannot feel pain,' and that we are therefore +at liberty to deal with them in any way we please. +Still it is as well to save all possible suffering, and be +satisfied with no killing box that is not practically +instantaneous in its effects.</p> + +<p>Among other poisons used by entomologists I may +mention sulphur fumes and tobacco smoke. The former may be +obtained by burning a little sulphur or a sulphured lucifer match +under the perforations of a killing box of the pattern described, and +the latter—well, every smoker knows that. I should at once condemn +the former method, at least for field work, as troublesome +and inconvenient; and as to the other, I have tried the effect of a +puff (and many puffs) of tobacco smoke on an imprisoned insect, +but was so dissatisfied with the result that I am not likely to do so +again.</p> + +<p>We have now considered a good many insecticides more or less +suitable to our purpose, but there still remains the unsolved problem +as to which is the best. Each one has its advantages. For +<i>convenience</i> nothing beats the cyanide bottle. It is very speedy in +its action, and the use of a bottle is a little preferable to a metal +box, for you can always satisfy yourself as to its efficiency without<!-- Page 73 --><span class="pagenum"><a name="Page_73" id="Page_73">[Pg 73]</a></span> +opening it. Cyanide, chloroform, benzole, and some others render +the insects more or less brittle and stiff, so that it is not so easy to +'set' them for the cabinet. Perhaps, if you happen to have a +supply of growing laurel close at hand, you cannot do better than +stick to the laurel box. The time taken in bruising up a few leaves +is inconsiderable, and the moisture given off from them will keep +your insects moist and supple, or will even 'relax' them if they +have become rigid. But try various plans for yourself, and you +will be able to settle a question which all the entomologists in the +world cannot answer for you—which method answers best in <i>your</i> +hands.</p> + +<p>The next item for our consideration is the 'collecting box.' +This is merely a box in which the butterflies are pinned as soon as +they are dead. Here, again, we shall note a few variations from +which a selection can be made according to the means or the +ingenuity of the reader. For a couple of shillings you can obtain +a good zinc collecting box, lined with cork, of oval form (a most +convenient shape for the pocket), and quite large enough for one +day's captures; and half that modest sum will purchase a wooden +box, also lined with cork, adapted to the same purpose.</p> + +<p>As with many other things, so with collecting boxes, the cheapest +is often the dearest in the end. You may feel inclined to save a +shilling by buying a wooden box, but you are sure to discard it after +a little practical experience for a metal one. We shall speak a little +later on concerning the advisability of 'setting' the butterflies as +soon as possible after capture; but this is not always practicable, +especially after a good day's catch. Now, if the insects are pinned +in a wooden box, they soon become dry and rigid, and consequently +cannot be 'set' till they have been put through the more or less +tedious process of 'relaxing.' If you use a wooden collecting box +you will often find, on a hot and dry day, that all or nearly all your +butterflies are rigid before you arrive home; but a metal box will +keep them moist and supple, so that you can even put off the +setting till the following day if you are unable to do it immediately +after your return.</p> + +<p>Another point worth considering is the best economy of space. If +your collecting box is only about one inch deep inside, you have +room for only one layer of pinned insects; but a box only a little +deeper may be lined with cork both at top and bottom, and thus be +made to accommodate double the number. The zinc boxes sold by +the dealers are generally lined with cork in this manner, and are,<!-- Page 74 --><span class="pagenum"><a name="Page_74" id="Page_74">[Pg 74]</a></span> +of course, deep enough for the double layer of specimens; but the +wooden boxes are sometimes lined on the bottom only. After these +few remarks you will at once see the economy of expending the +extra shilling on the former.</p> + +<p>Although the prices of collecting boxes are low, yet there are +many who would prefer making their own, and there is much to be +said in favour of this. A great deal of pleasure is to be derived +from the construction of your own apparatus, especially when that +apparatus is afterwards to be used in the pursuit of a delightful +hobby. During the whole of the time thus engaged, you are looking +forward with the most pleasurable feelings to the glorious treat +before you, and every joint you make seems to bring you nearer to +the realisation of your joys. During the bleak winter months there +is no better employment for an entomologist who has a little spare +time than the preparation for the next outing. It is just one of +those artful schemes by which he seeks to get as much pleasure out +of life as it is capable of affording. How many there are who, +for the lack of a pleasant and instructive hobby, find their leisure +hours the most dismal of all, and who complain of the toil and +wearisomeness of their lot! The mournful thought with them is, +'Is life worth living?' but who ever heard such an expression from +the lips of an active entomologist?</p> + +<p>But I must have done with moralising and proceed to business. +The question is—How shall we set to work about the construction +of a collecting box? If it is to be a wooden one, select or make a +box of such a size as to suit your pocket or satchel, and cover the +bottom, and lid too if the depth allows of it, with sheet cork or +slices of good wine corks, about one-eighth of an inch thick, fixed +on with glue.</p> + +<p>The metal box is not quite so easy, but even here you may +save yourself much work by keeping your eyes open. Very neat +little collecting boxes can be made out of the flat metal boxes in +which are sold certain favourite brands of tobacco. Some of these +are just the right depth, and also of a very convenient size for the +coat pocket. Beg one of these boxes from a smoking friend, and if +the lid is not held by a hinge (a great advantage, by the way), you +can easily solder on a brass one.</p> + +<p>All that remains now is the fixing of the cork. Buy a sheet +of cork at a naturalist's shop, this being a commodity always in +stock, and cut out two pieces just the size to cover the bottom +and the lid.<!-- Page 75 --><span class="pagenum"><a name="Page_75" id="Page_75">[Pg 75]</a></span></p> + +<p>Gum and glue are not very satisfactory as fixing agents, for, as +you will presently learn, there are times when it will be necessary +to keep the box moist, and moisture softens both these substances. +The cork must be fixed by means of little strips of metal. Here +are two ways of doing this:</p> + +<p>First.—Cut a few little strips of sheet tin, each about two inches +long and one-eighth wide. Double and bend them as shown in +<a href="#FIG_46">fig. 46</a>, and solder them to the surfaces which the cork is to +cover (<a href="#FIG_47">fig. 47</a>). As the cork is pushed in its place, these little +slips are allowed to force themselves through slits in it made by +means of a penknife, and then the ends are bent over as shown in +<a href="#FIG_48">fig. 48</a>. Two or three such fasteners will be quite sufficient to hold +down each sheet of cork.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_46" id="FIG_46"></a> +<img src="images/i_092a.jpg" width="300" height="134" alt="" title="" /> +<span class="caption">Fig. 46.</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_47" id="FIG_47"></a> +<img src="images/i_092b.jpg" width="300" height="138" alt="" title="" /> +<span class="caption">Fig. 47.</span> +</div> + +<div class="figright" style="width: 400px;"> +<a name="FIG_48" id="FIG_48"></a> +<img src="images/i_092c.jpg" width="400" height="93" alt="" title="" /> +<span class="caption">Fig. 48.</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_49" id="FIG_49"></a> +<img src="images/i_092d.jpg" width="300" height="83" alt="" title="" /> +<span class="caption">Fig. 49.</span> +</div> + +<p>Second.—Put the sheets of cork in their places <i>first</i>, then +make a few little slits through both metal and cork with the +point of a penknife, and then bind the two together with a +few ordinary paper fasteners. This arrangement is shown in +section in <a href="#FIG_49">fig. 49</a>.</p> + +<p>Just one point more concerning the metal collecting box. You +will often call moisture to your aid in keeping the butterflies +flexible and soft. This will have but little action on zinc, but will +sooner or later cause the 'tin' (really tinned iron) box to rust. +Here, then, is a point in favour of zinc, but still a home-made 'tin' +collector will last a long time if kept dry when not in use.</p> + +<p>As already hinted, there are times when it is desirable to take +home certain butterflies alive, either for a study of their movements +or for the purpose of securing eggs for breeding. To this end you +must provide yourself either with a number of 'chip boxes' with a +few small holes pricked in the cover, or with some metal boxes +with perforations for the admission of air. If the latter, you will<!-- Page 76 --><span class="pagenum"><a name="Page_76" id="Page_76">[Pg 76]</a></span> +have no difficulty in securing a few 'tin' boxes of suitable size, +but, as the surface of the metal is very smooth, you should always +introduce a few leaves or something else that will provide a foothold +for the inmates.</p> + +<p>The last item of the outfit is the pins. Ordinary draper's pins +are quite out of the question. They are far too thick and clumsy for +the collector's work. If you are not already acquainted with the +'entomological pins,' you had better ask a dealer to give you a +sample card. This will be very useful for reference until you +become well acquainted with the various lengths, thicknesses, +numbers and prices. The card will contain one of each kind, with +price and number attached.</p> + +<p>If you fix a butterfly with the ordinary pin, you may find the +latter partly covered over with verdigris after a time. This bright +green substance is formed by the action of decomposing animal +matter on the copper of the pin, and gives a very unsightly appearance +to the specimen. To avoid this the entomological pins are +either silvered, blackened or gilded. The silvered pins tarnish +after a time, but the two other kinds keep their colour well, and +are therefore better. The gilded ones are rather expensive and unnecessary, +and perhaps the black ones are to be preferred to the +silvered, although they are rather more costly.</p> + +<p>Most dealers will supply you with a box of mixed pins, each box +containing about six different sizes. This is very convenient for +those who work in a rather small way; but if you intend to make +entomology a prolonged study you had better get an ounce or so of +each of the more useful sizes.</p> + +<p>Butterflies vary much in size, and Nos. 3 to 8 are the most +useful sizes of pins to fix them; No. 3 being for the largest, and 8 +for the smallest.</p> + +<p>Supposing all the foregoing requisites to be quite ready, still you +are really by no means prepared for all your work. The butterflies +captured should be set as soon as possible after your return, and +everything required for <i>this</i> part of the work must be in perfect +trim. Yet I think it will be more convenient just now to confine +our attention to the subject of 'Catching Butterflies,' leaving all +the indoor work to form the substance of another chapter. Our +next point, then, shall be the consideration of seasons, times, and +localities.</p> + +<p>The earliest of the butterflies make their appearance on the +wing in April, or, if the weather is mild, towards the end of March;<!-- Page 77 --><span class="pagenum"><a name="Page_77" id="Page_77">[Pg 77]</a></span> +and from this time you can find employment up to the end of +September or the beginning of October—a period of about seven +months. But it must not be supposed that all parts of this long +season are equally prolific, and will yield equally valuable catches. +Remember the short term of a butterfly's life, and bear in mind +that each one has its own regular season in which to spend the +winged state; you will then see that anyone who wishes to 'work' +as many species as possible must arrange his outings in accordance +with the insects' own times.</p> + +<p>Some butterflies are double-brooded, and the two broods may +not come forth at certain fixed times. Hence they seem to be on +the wing almost without cessation for several months together, and +therefore need not have a special day set apart for them. But +others are more uniform in their date of appearance, and die off at +about the same time. To catch such as these you must be careful +to watch the weather, make allowance for any severities that may +tend to cause a delay, or an unusually high temperature that may +hasten their emergence, and then select a day in which you may +expect to find them fresh and unworn. A week too early, and none +are to be seen; a week too late, and nearly all you catch are worn +and worthless.</p> + +<p>A glance at our Calendar (<a href="#APPENDIX_II">Appendix II</a>) will give you a few +illustrations in point. Thus you will observe that May is a month +for the 'Whites,' early 'Blues' and certain of the Fritillaries; +July for most of the Hairstreaks and Browns, and so on. Before +you have been long collecting you will have captured the very +common species, and then you will find that your butterfly hunts +are very unproductive unless you make it a point to try for certain +species at the proper times.</p> + +<p>Time, however, is not the only thing to take into account when +preparing for a day with the butterflies. It is equally important +that we should carefully select our locality in accordance with the +known haunts of the various species. As long as you are simply +working up the common kinds, you may wander almost at random +in waste places, flowery meadows, corn fields, railway banks, &c.; +but when you have secured a few specimens of each of these, you +must search out the favoured resorts of the more local and the +rarer species. For instance, wooded spots must be visited if you +are to take certain of the Fritillaries, oak woods for the Purple +Emperor and the Purple Hairstreak, fenny districts for the beautiful +Swallow-tail, and so forth. In some cases the butterflies are<!-- Page 78 --><span class="pagenum"><a name="Page_78" id="Page_78">[Pg 78]</a></span> +closely restricted to certain isolated localities, to which you must +travel if determined to obtain them.</p> + +<p>There yet remains another important matter to consider, and +that is the kind of day you shall select for your outing. Butterflies +are not only strictly day-fliers, but most of them venture out only +on bright days. Always choose as hot a day as possible, with a +very bright sun. If you are to be out for a full day's collecting, +manage to be on the hunting ground at about ten o'clock in the +morning. As a rule there are not many out before this time, and +some do not appear to stir till an hour later: still there are a few +'early birds' among them, one of which—the Wall Butterfly—I +have seen on the wing before eight.</p> + +<p>If your season, your day, and your locality are all well chosen, +you may reckon on a good six hours' work. At about four the +butterflies begin to lag, and then drop into their hiding places, one +by one, till only a few of the late stragglers remain on the wing.</p> + +<p>So far I have furnished some general instructions that may be +regarded as preparatory to the start; but I will now give a few +hints as to the mode of procedure when the day for field work has +come.</p> + +<p>First, see that you have secured <i>all</i> your apparatus, and that it +is in perfect condition. What is more annoying than to find, after +you have travelled some miles to get to your hunting ground, that +you have left your screw ferrule at home, or that the soldering of +your metal <span class="lettershape">Y</span> is just giving way? If you are troubled with a short +memory, it will be advisable to make out a list of every requisite +for your field work, and keep this for reference on all field days.</p> + +<p>Here is a list of your equipment for a day with the butterflies. +Net, ferrule or <span class="lettershape">Y</span>, stick, collecting box (the cork of which should be +damped if the box is a metal one), a few 'chip boxes' for live +insects, killing apparatus, a good supply of pins of several sizes, a +piece of string, needle and cotton, and your penknife.</p> + +<p>You observe in this list one or two items not previously mentioned, +since they hardly come under the category of apparatus, +but a moment's thought will convince you of their usefulness, especially +in the case of a breakdown. If your net catches in a thorn—a +very common occurrence—and a big rent is made, the needle and +cotton will save you a deal of agony, and perhaps loss of temper. +If your stick breaks under your exertions, the knife or the string +may prove a most valuable companion. Your pins may be stuck +in the cork of your collecting box, certainly the most convenient<!-- Page 79 --><span class="pagenum"><a name="Page_79" id="Page_79">[Pg 79]</a></span> +spot for immediate use; but you may also have a reserve store in +a small pocket cushion, or arranged neatly on a strip of flannel +which can be rolled up in the waistcoat pocket.</p> + +<p>At last you are on the hunting ground, fully equipped but inexperienced, +and at first find yourself just a little awkward in the +use of your new gear. Your experience with the cap has been a +very wide one, and you are possibly an expert at knocking down +'Whites' in the streets and in your neighbour's kitchen gardens. +Now you have to wield the net, and coax your captives into your +killing bottle; hence a slight feeling of incompetence at first.</p> + +<p>You soon get over this, however, and within five minutes you +may be seen furiously slashing away at all the poor butterflies that +come within range, common 'Whites' and dingy 'Browns' receiving +as much attention at your hands as any rare gem that +may happen to cross your path.</p> + +<p>How different are the movements of an experienced collector! +He walks stealthily along the route he has chosen, apparently +taking but little notice of the majority of butterflies that approach +and pass him. He has already secured his 'series' of nearly all +the species, and is carefully on the watch for the gems that are +required to complete his cabinet. His actions are slow and deliberate +rather than rash; and he trusts more to his eyes than his +legs.</p> + +<p>The beginner may take to his field work quite to his own satisfaction, +and may travel homeward with a feeling of great pride over +his first day's catch; but yet there are a few points in which a little +advice may not be quite out of place, particularly so with regard to +the management of the net, and the killing and pinning of the +insects.</p> + +<p>Most of the butterflies may be caught on the wing, and it is far +better to net them in the air than to sweep them off the herbage +and flowers. If these are rather low, you should strike the net +smartly <i>upwards</i> from below them, but of course this movement is +impossible with insects that happen to be almost above your reach. +If a butterfly is busily engaged in searching out its sweet food, +flying from flower to flower, don't think of giving chase, but follow +it up stealthily, and you will sooner or later get an opportunity of +striking at it while in the air. Sometimes, however, you will see a +powerful flier making a straight dash across your field, taking no +notice whatever of the fragrant blossoms, but evidently engaged on +some important errand. If such happens to be a species you<!-- Page 80 --><span class="pagenum"><a name="Page_80" id="Page_80">[Pg 80]</a></span> +require, then you must run for it, but you will probably be satisfied +with only a few chases of this kind, particularly if the sun is very +hot, and the ground diversified with clumps of furze, heather, +'molehills,' and ditches.</p> + +<p>There are times when your only plan of netting a butterfly is +to sweep it from a flower or leaf on which it has settled. If the +vegetation is very low, you have simply to bring the net down upon +it, and then, holding up the apex of the net with the other hand so +as to give it room to fly, you can inclose it by grasping the lower +part of the net as soon as the butterfly has fluttered upward. If +the herbage is tall it is advisable to strike either upward or sideways +at the insect, starting it from the leaf or flower on which it rests; +for if you bring <i>down</i> the net you will have to inclose the whole or +part of the plant on which the butterfly has settled—a procedure +that often ends in a torn net, or in the insect becoming damaged +through being rubbed against the plant.</p> + +<p>Whenever you capture a butterfly by a sweep of the net +through the air, you immediately turn the ring into a horizontal +position, so that the bag of the net closes itself as it falls over the +edge. This gives you an opportunity of examining the insect before +you introduce your killing bottle. This is a very necessary precaution, +for you are generally unable to judge of the condition of a +butterfly while on the wing, and in some cases you cannot even be +certain of the species. If, then, you were to call the killing bottle +into requisition for every capture you make, you would certainly +find yourself taking the life of many an insect that is of no use +whatever to you. Always examine your specimens at the moment +they have been secured, at least as far as it is possible to do so, by +looking through the gauze; and let your examination be as brief as +possible, or some of the butterflies that were at first in splendid +condition will render themselves useless to you during their +struggles to get away.</p> + +<p>When satisfied that an insect is likely to be of value to you, keep +it in the apex of the net by grasping the bag beneath it with the +left hand, and then introduce the opened killing bottle with the +other hand. As a rule you will experience not the slightest difficulty +in coaxing it into its trap, and then you quickly cover the +mouth of the killing bottle with the gauze, then apply your left +hand, using it as a temporary stopper for a few seconds, and now, +the insect having been quieted, replace the cork.</p> + +<p>A good killing bottle is almost instantaneous in its action, not<!-- Page 81 --><span class="pagenum"><a name="Page_81" id="Page_81">[Pg 81]</a></span> +only stupefying, but immediately killing the insects; and as soon as +you are sure that each specimen is quite dead, you may pin it in +your collecting box.</p> + +<p>You must be cautious, however, on the one hand, that you do +not take it out too soon. If you do you may find that it recovers +from the mere stupefying effect of the poison, even after it has been +pinned, and when you open your collecting box for the next butterfly, +you are horrified at the sight of the poor victim struggling to +free itself.</p> + +<p>On the other hand, don't keep the insects in the killing bottle +too long. If you do you will soon have a number, one lying on +another, and all tumbled about together while you are on the chase. +Of course, under such circumstances you are sure to damage them +more or less.</p> + +<p>Many collectors, although they may always use a killing bottle for +moths, never employ one for butterflies, but kill them by pinching +the thorax. It is well to know how to do this, for it sometimes +turns out to be a really quicker process than that we have just been +considering; and, more than this, you can resort to it should you +break or lose your bottle while in the field. It is done in this +manner: Bring the two opposite sides of the net together, closing +them on the insect so that it cannot flutter. If now the wings are +brought together over the back, all is right, but if not, give it just +a little room to flutter till you have the opportunity of closing the +gauze upon it with the wings in the desired position. Now pinch +the thorax smartly between the finger and the thumb, applying the +pressure outside the net, but be careful not to squeeze the abdomen. +In a moment you will find the insect quite dead, and not in the +least damaged unless you performed the operation clumsily.</p> + +<p>Now as to pinning. Hold the dead butterfly between the finger +and thumb of the left hand, and pass a pin of convenient size through +the centre of the thorax above, and push it through so that the point +appears centrally on the under surface. It is now ready for your +collecting box.</p> + +<p>So you work on till the sun begins to get low, and the butterflies +become fewer and fewer, till only a few stragglers of common species +are to be seen. Still there are a few hours of daylight and perhaps +even of bright sunshine before you, and if you are not weary with +the work done, you may very profitably spend these hours in the +collection and study of the habits of moths.<!-- Page 82 --><span class="pagenum"><a name="Page_82" id="Page_82">[Pg 82]</a></span></p> + + +<h4><i>Catching Moths by Day</i></h4> + +<p>The reason for choosing the sunny hours for butterfly collecting +is obvious, all these lovers of brightness being then actively on +the wing; and although many may be driven out of their hiding +places by beating the herbage with the handle of your net, or even +be searched out as they rest on stalks and leaves during dull days +or at morning and evening twilight, yet such methods are comparatively +tedious and unproductive.</p> + +<p>Some moths also are lovers of sunshine, and while engaged in +butterfly hunting you will often meet with a moth flying briskly +from flower to flower and taking its fill of both sweetness and +brightness. Again, as you wade among flowery herbs in quest of +butterflies you will certainly disturb a number of moths, causing +them to take a short flight in search of a safer spot. Thus you will +almost invariably find a few moths among the contents of your +collecting box even though you made no special effort to seek +them out. But we shall now see how we may set to work to +obtain a successful catch of moths at times when butterflies are +not so much in demand, or during the less brilliant hours of the +day, when butterflies are at rest.</p> + +<p>The apparatus required for this work need not differ in any important +respect from that recommended for butterflies. The same net is +used, any reliable killing bottle will do, and the pins and collecting +box used for butterflies are equally serviceable. But your mode +of procedure is very different.</p> + +<p>As you walk towards your proposed hunting ground you will +do well to examine the trunks of trees, old walls, and wooden fences. +In this way you will meet with moths fast asleep, which are +consequently easily taken. All you have to do is to hold the open +killing bottle obliquely just below the insect, and then push it +gently downward with a small twig or stalk. As a rule the moth +will drop direct into the bottle and make no attempt to fly away; +but some are very light sleepers, ready to take flight at the slightest +disturbance; and when dealing with these you must be careful to +bring the mouth of the killing bottle so closely round them that +there is no room for flight except into the bottle itself. It is well, +however, not to take long at this kind of searching, but to reserve +as much as possible of your time for what you consider to be a +very favourable locality.</p> + +<p>Speaking generally, a good locality for butterflies is a favourable<!-- Page 83 --><span class="pagenum"><a name="Page_83" id="Page_83">[Pg 83]</a></span> +one also for moths, and you will do well to give special attention +to well-grown hedges, especially those that surround clover fields; +also overgrown banks, the borders of woods, open spaces in woods, +the trunks of isolated trees, gravel pits, and old chalk quarries.</p> + +<p>Walk beside or among the undergrowth of woods, or among the +tall herbage of waste places, tapping the branches and twigs with +the handle of your net as you go. Then, if your locality is well +selected, you will rouse moths to flight at almost every stroke. +Some of these will shoot upward among the lofty branches and +disappear quite beyond your reach; others will fly rather low and +somewhat heavily, giving you favourable opportunities to try your +skill with the net; others, again, will fly only a yard or so, and +alight on a neighbouring leaf, often remaining so quiet that the +killing bottle is easily made to inclose them.</p> + +<p>There are moths that show a decided preference for large trees. +These may be seen hovering about high branches during the evening +twilight, and sometimes even in sunshine. In many such +cases the chance of a capture seems hopeless, but occasionally one +will descend so low that a watchful collector is able to secure it by a +sweep of the net.</p> + +<p>If at any time you are in a locality by day where you suspect +the presence of certain species of moths at rest among the upper +branches of trees, such branches should be beaten if possible to dislodge +the insects they may shelter. A long stick will often serve +this purpose well, and, failing this, a few stones thrown among +the branches may prove effectual. In the case of small and rather +slender trees, a kick against the trunk will set the whole in vibration +sufficient to surprise all the lodgers; and the same effect may +be produced with larger trees by giving each a good sound blow +with a mallet or some other suitable implement.</p> + +<p>This or any other plan of 'beating' for moths is much more +conveniently worked by two collectors together than by one alone; +for one engaged in beating the herbage cannot be at the same +time fully on the alert with the net. If two persons are together, +one may take the lead, armed with the beating stick only, while +the other, only very slightly in the rear, is always ready to +strike.</p> + +<p>We have said that butterflies should always be killed in the +field, but this plan is not so universally adopted with moths. Many +collectors carry a large supply of pill boxes when going out for the +latter and then take as many as they possibly can by boxing them<!-- Page 84 --><span class="pagenum"><a name="Page_84" id="Page_84">[Pg 84]</a></span> +direct in these. This method of 'pill-boxing' is very simple in +the case of the lazy and soundly sleeping moths. It is only +necessary to hold the open box below the insect, and then cause +it to fall by pressing the lid down gently on it from above.</p> + +<p>Many of the moths so caught will remain quiet in the boxes +and can be taken home alive without much fear of damage. All +may then be killed at the same time by packing all the pill +boxes in some vessel of sufficient accommodation, and shutting +them in with a little chloroform, ammonia, benzole, or other +suitable poison. The vapour will soon find its way through the +pores of the pill boxes, but, in order to make its action speedy, +each one should have a few perforations in the lid.</p> + +<p>Whatever advantages this method may give to the collector +who works at night, when the process of pinning would be more +or less tedious, there is no necessity for its adoption during the +day. The large number of pill boxes required is certainly far +more bulky than the single collecting box that would accommodate +all the day's captures; and although most of the insects boxed +alive may be none the worse for the shaking they get, and may not +damage themselves by fluttering in their small prisons, yet there is +often a little loss on this score.</p> + +<p>If you do adopt the pill-boxing method, be very careful +that you do not mix the occupied boxes with the empties; and unless +you fix on some definite plan for the prevention of such an +occurrence, you will often find yourself releasing a prisoner from a +box you have just opened to receive a new-comer.</p> + +<p>Suppose that you start with all your empties in your right +pocket. Then each one, as soon as it is tenanted, might be placed +in the <i>left</i>, with the name of the insect, or any particular concerning +it you would wish to note, pencilled on the lid.</p> + +<p>When examining the trunks of trees you will be continually +meeting with specimens of very small Moths—<i>Pyralides</i>, <i>Crambi</i>, +<i>Tortrices</i>, and <i>Tineæ</i>—and at first may find some difficulty in +boxing or bottling such small and delicate creatures. A grass +stalk will enable you to tip some of them into your killing bottle, +but some are so snugly packed in crevices of the bark that it is +almost impossible to get them out without damage, even with a +thin and slender stalk. But a sudden puff of wind from your +mouth will often be sufficient to dislodge them and blow them +into your net, and from this they are easily transferred to a box or +bottle.<!-- Page 85 --><span class="pagenum"><a name="Page_85" id="Page_85">[Pg 85]</a></span></p> + +<p>These few hints will prove sufficient to start you on moth-hunting +expeditions during the daytime, and will enable you to +make good use of the dull days and cloudy hours when the butterflies +are quiet; but we must now turn our attention to the night +work of the entomologist, and see how we may attract and catch +moths during their hours of work and play.</p> + + +<h4><i>Searching for Moths at Night.</i></h4> + +<p>It is a well-known fact that the night-flying moths are attracted +by lights, a characteristic of these insects that it is difficult to +explain. Their love of darkness is in many instances so decided +that they absolutely refuse to take flight while the fading light of +day still lingers on the horizon, and even display a great aversion +to the rays of the moon; and yet these very same species will +often rush madly into the fierce glare of a naked artificial light, or +fly with an energy almost amounting to fury against the glass of a +street lamp or lighted window.</p> + +<p>Puzzling as this peculiar tendency is, we can profitably turn +it to our own account by making it a means of luring a number of +moths into our presence.</p> + +<p>The simplest way of putting this mode of capture into effect is +to post yourself at your open window, with net and cyanide bottle +at hand, while the brightest light you can command casts its rays +as far and as wide as possible into darkness outside. If you use +an oil lamp for the purpose, let it stand just inside the window +frame, or, if a jointed gas bracket happens to be situated beside the +window, bend it round so that the rays may pass over a wide area +outside.</p> + +<p>Two such lights are sometimes a very decided advantage—one +quite outside the window to attract the moths from all possible +points, and then another near the middle of the room to invite +them inside. Whether you use either one or two lights, always +see that it or they are so surrounded by a screen that the moths +cannot by any possibility rush into the flame. There is nothing +better for this purpose than a covering of light gauze, for this is +not only a barrier for the prevention of the suicidal tendencies of +the insects, but it also gives a good foothold to those who would +like to rest and enjoy the luminous feast.</p> + +<p>You will soon begin to learn that moths, like ourselves, exhibit +great differences in their ways of enjoying their festal moments.<!-- Page 86 --><span class="pagenum"><a name="Page_86" id="Page_86">[Pg 86]</a></span> +Some will satisfy themselves by flying <i>near</i> the light in almost a +straight course, hardly slackening their speed as they pass; or will, +perhaps, make a hurried curve round the light and then pass on at +once about other business. To catch these you must be always on +the alert, with net in hand, ready to make a dash at the right +moment. But many will make straight for the flame, and then, +finding a barrier in the form of gauze or glass, will either flutter +round and round as if dissatisfied with your attempt to save them +from an untimely end, or else settle quietly on the screen to enjoy +the brightness for a long period. The flutterers are usually easily +covered by a glass or the open cyanide bottle, and as for those that +settle down quietly, you can take them at your leisure.</p> + +<p>It will not do for a collector to depend solely on this method of +obtaining moths, but at times when either his duties or the bad +weather keeps him at home it affords him a means of capturing a +few specimens that otherwise would have been missed. He may +be even so busily engaged in other matters that he cannot afford +the time to stand and watch with net in hand, but the insects that +fly into his room and dance round the gas jet or inquisitively +examine the white surface of the ceiling are easily netted or boxed +without much loss of time.</p> + +<p>The chances of success at this kind of work will vary considerably +with the aspect, the season, and the weather. If your +window opens on a large flower or fruit garden, on a patch of +wooded country with plenty of underwood, a piece of waste ground +overgrown with rank vegetation, or a stretch of heath or moor, +then you may expect a very large number of visitors; but if you +are situated on a level and barren country, or in the dense +atmosphere of a thickly populated district, you must not reckon on +many intruders.</p> + +<p>As regards the season, this is more extended than that of the +butterflies. A few species of moths may give you a call during +the bleak nights of October and November, and also during the +somewhat less dismal nights of February and March; but from +April to September you may rely on a goodly number of captures. +Of course you will not expect many of the 'rarities' and 'gems' +to find you out; these are to be searched for in the open field in +the manner to be presently described; but your lights will attract a +large number of the commoner species of <i>Geometræ</i> and <i>Noctuæ</i>, +the former <i>chiefly</i> during the early summer, and the latter more +or less throughout the season.<!-- Page 87 --><span class="pagenum"><a name="Page_87" id="Page_87">[Pg 87]</a></span></p> + +<p>A little experience will show you that the atmospheric conditions +form a very important consideration. The dark and warm +nights are the most productive. Very little luck is to be anticipated +when the full moon is throwing down her silvery rays from a clear +sky; nor will you see many while a cold east or north-east wind is +blowing. Under these conditions many moths prefer to keep in the +sheltered nooks where they slept away the sunny hours of the day. +They love a warm and moist air such as calls forth the odours of +the fragrant blossoms that provide their sweets, and show no dislike +to a fine drizzling rain that you yourself would prefer to avoid. A +pelting shower will generally keep them under cover, but they +delight in the fresh and moist air that immediately +succeeds the passing storm.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_50" id="FIG_50"></a> +<img src="images/i_104.jpg" width="300" height="400" alt="" title="" /> +<span class="caption">Fig. 50.—Frame +of Net for Collecting +Insects +on Lamps and +Windows.</span> +</div> + +<p>If you reside on the outskirts of a town an +occasional tour of inspection of street lamps +may add a few specimens to your collection, and +some entomologists attach so much importance +to the value of these luminaries that they provide +themselves with a special net for the removal of +moths from the glass and rails (<a href="#FIG_50">fig. 50</a>). The +straight side marked <i>a</i> is applied to the panes +of glass when flutterers or settlers are to be +taken, and the bend on the opposite side is to +secure those that rest on the rail.

Three sheets of glass are now to be placed as shown in the +sketch (<a href="#FIG_51">fig. 51</a>), one upright piece completely shutting off the lamp, +and two others placed obliquely with a space between them just +large enough to allow admission. These must be exactly the +width of the box, and should not be permanently fixed, but simply +resting on small wooden supports nailed on to the sides. When required +for use, it is only necessary to light up the lamp, strew some +dead leaves on the bottom of the box, and put the sheets in their +places. It will be seen at once that the angles at which they are +placed will direct all light-seekers into the lower compartment, +whence they are not at all likely to find their way out again; and +after vain endeavours to reach the light they finally settle down on +the sides of the box or seek shelter among the dead leaves.</p> + +<div class="figleft" style="width: 400px;"> +<a name="FIG_51" id="FIG_51"></a> +<img src="images/i_105.jpg" width="400" height="313" alt="" title="" /> +<span class="caption">Fig. 51.—A Trap for Catching Moths.</span> +</div> + +<p>Occasionally it happens +that an entomologist +is lucky enough to claim +the friendship of a person +who, from the nature of +his calling, is peculiarly +well qualified to render +him great assistance. +Thus a friendly lamplighter, +expert and patient +in the use of the cyanide +bottle or pill box, is capable +of giving valuable aid at +times; and the keeper of a +lighthouse has it in his power to capture many a gem that is seldom +seen on the wing; but, although much may be done by means of +these and other stationary lights, this kind of work does not compare +favourably with the night rambles of a naturalist in the very +haunts of the objects of his search.</p> + +<p>For such out-door work in search of moths a good lantern is +essential. An ordinary 'bull's-eye' is almost useless, for, although +it concentrates a good light on certain objects, the narrow range of +its rays constitutes a strong objection to its use for entomological +work. For this purpose it is necessary that the rays of light not +only pass in front of you, but also shoot off right and left to warn you +of the approach of a moth before it is too late to wield the net. +This wide range may be obtained by means of three flat glass sides, +or, better still, by a bent plate glass front.<!-- Page 89 --><span class="pagenum"><a name="Page_89" id="Page_89">[Pg 89]</a></span></p> + +<p>In addition to this you must go out provided with your net, +killing bottle, and a number of pill boxes. Choose your night +according to the hints already given, and if you are on the look-out +for any particular species, be careful that the date of your outing is +well timed, making any necessary allowances for the forwardness +or backwardness of the season, for a moth that is generally due on +a certain <i>average</i> time of the year may appear some weeks sooner +if the preceding weeks have been unusually warm, or its emergence +may be delayed considerably by the prevalence of cold east +winds or a late frost.</p> + +<p>Make up your mind as to the field of your operations before you +start, and if possible choose a route that will carry you through a +variety of situations, so that you may pass the favourite haunts of +a number of different species. Clearings in woods with an abundant +undergrowth, waste places with plenty of tall and rank vegetation, +overgrown railway banks, clover fields, the flowery borders of corn +fields, plantations in parks, heaths and moors, sheltered and overgrown +hollows such as chalk pits and old disused quarries, reed and +marsh land, all these are good localities, each one inhabited by its +own peculiar species, and if your route runs through a fair variety +of such places you may, other things being equally favourable, +depend on a good catch.</p> + +<p>See that your time also is well chosen. Of course you cannot +say exactly what the night will be till it actually comes, and, as +you have to start off before it is dark, you must consider the +probabilities of the future from the present condition of the air. Let +it be a night when a bright moon is not due, and if it follow a +warm and moist day with a south or south-west wind, or if drizzly, +so much the better; but let your feet be shod with boots that will +permit you to wade through moist herbage without danger, and +take a waterproof if necessary.</p> + +<p>It is always advisable to be on your hunting ground before +twilight sets in, as a number of moths venture out before the sun +has disappeared; and then you can work on till midnight if you +feel inclined, or even extend your labours till the early hours of the +morning.</p> + +<p>Before dusk you will meet with many of the little <i>Tortrices</i> +(<a href="#Page_298">page 298</a>) in sheltered spots, and a little later the <i>Geometræ</i> and +Hawks will be on the wing. Thus, before dark, you may make +good use of your net, dealing with your captures just in the same +way as recommended in the case of butterflies.<!-- Page 90 --><span class="pagenum"><a name="Page_90" id="Page_90">[Pg 90]</a></span></p> + +<p>After a time, however, the lantern will have to be brought to +your assistance in making known the whereabouts of the later +species, consisting chiefly of the <i>Noctuæ</i>, many of which do not +make their appearance till it is quite dark. If now you carry your +lantern in your left hand, your work will be rendered somewhat +difficult and tedious, for, although one hand is sufficient to manage +the net properly, you are compelled to rest your light on the ground +every time you make a capture, as it is impossible to box your +specimens unless both hands are quite free. This difficulty is easily +overcome by suspending the lantern by means of a string or strap +placed round your neck, allowing it to hang on your chest; and a +further advantage is gained by having a second strap round your +chest to prevent it from swaying about with every movement of +your body. This arrangement gives you both hands perfectly free +during the whole time, and also prevents the necessity of continually +bringing yourself into a stooping or kneeling posture +while you are examining or boxing the specimens you have +netted.</p> + +<p>There are now two courses open to you. Either you can kill +and pin the moths as you catch them, fixing each one securely in +the collecting box, or you may simply shut each one in a separate +pill box and leave the remainder of the work to be done at home. +If the ordinary collecting box only is used, a little of your time is +necessarily occupied in pinning and transferring, and if many +insects are about such an occupation may appear to you to be a +waste of valuable time. But this is not all. Often and often will +you find that while thus engaged a splendid moth will come and +flutter round your light; and, before you have time to drop your +collecting box and pick up the net, the fine creature you would +have prized has darted off again. This certainly seems to speak in +favour of the pill-boxing method, but it must be remembered that +a few of the moths will continue to flutter after they have been +boxed, so that when you arrive home they are more or less +damaged, a large number of the scales that once adorned the wings +now lying on the sides and bottom of the boxes. Perhaps the best +plan is to take both the collecting box and also a quantity of pill +boxes, and a little experience will soon show you which is the +better accommodation for certain kinds.</p> + +<p>Particular attention must be paid to flowers, some of which are +very attractive to the <i>Noctuæ</i> especially.

It consists of a long and stout stick, at the top of +which is a tubular joint (<a href="#FIG_52">fig. 52</a>) that might be termed a <span class="lettershape">T</span>-piece +were it not that the smaller part does not stand out at right angles +to the other. In this is fixed, in a straight line with the stick, a +short rod on which hangs a lantern—an ordinary bull's-eye answers +well here; and in the smaller tube is another short rod carrying a +shallow basin-shaped net, and of such a length that the net is just +in advance of the lantern.</p> + +<p>At first sight this arrangement will strike you as being very +unsatisfactory, there being no kind of trap to prevent the escape of +the insects. But it must be remembered that moths are more or<!-- Page 92 --><span class="pagenum"><a name="Page_92" id="Page_92">[Pg 92]</a></span> +less addicted to habits of intemperance—that they will hold on to +the supply of the sweet fluid they enjoy till they are ready to drop +with intoxication. This being the case, some will fall into your +net as soon as they are startled by the sudden and near approach +of the glare of your lamp, and others are easily <i>made</i> to fall therein +by gently tapping the flower-bearing stems from below with the +edge of the ring.</p> + +<p>Having become acquainted with this very sad propensity, which +thus brings ruin to so many unfortunate moths, can we not yet +further turn their evil doings to our own profit in our endeavours +to become acquainted with their structure and history? Most +certainly we can. All we have to do is to distribute in their haunts +a bountiful supply of some artificial intoxicant such as they love, +and then lie in wait for the victims that fall a prey to our snare. +This process is known to entomologists as 'sugaring,' and is a +splendid means of securing an abundance of species, often including +some rare ones that are scarcely to be obtained by any other plan. +Let us now inquire into the <i>modus operandi</i> of this interesting +operation.</p> + +<p>The first thing to do is to prepare the luring sweetmeat. Supply +yourself with a quantity of strong, dark treacle, and also some dark +brown sugar; always remembering, in the selection of these viands, +that odour rather than purity is to be the guide. The best kinds of +sugar are those very dark and moist brands imported in a raw state +from the West Indies, nothing being better than that known as +'Jamaica Foots.'</p> + +<p>Mix about equal quantities of these with a little stale beer, and +boil and stir till all the sugar is dissolved. The consistency of the +mixture should be such that it will work well with a brush when +used as a paint—not too thick, nor so thin that it is easily +absorbed by the substance on which it is 'painted,' nor must it be +in such a fluid condition that it easily runs.</p> + +<p>When satisfied on these points, transfer the mixture to a tin +canister, see it properly covered, and set it aside as your 'stock' +from which you can draw supplies as required. Now secure an +ordinary painter's brush of convenient size, and a number of strips +of linen or other rag, each one of which is fastened to a hook formed +of bent wire. These items, together with the usual lantern, collecting +box, pill boxes, and killing bottle, complete your outfit for the +sugaring expedition.</p> + +<p>When the selected time for operations has arrived, take sufficient<!-- Page 93 --><span class="pagenum"><a name="Page_93" id="Page_93">[Pg 93]</a></span> +'sugar' for your night's work, mix it well with sufficient +strong rum to give it a very decided odour, and start off at dusk +with this and the other requisites just mentioned.</p> + +<p>The night chosen should be warm and calm, with a rather damp +atmosphere, and no moon preferred. Let your locality be a well-wooded +one; abounding, if possible, with giant oaks and other trees, +and containing open spaces with plenty of underwood and rank +herbage. Such localities are to be met with at their best in forest +lands, and if you would do wonders at sugaring you cannot do better +than arrange for spending your holidays in such a spot as the New +Forest, taking with you sufficient 'sugar' for several nights' work.</p> + +<p>Having reached a likely spot of no very great extent, you prepare +for real work. Light up the lamp, and get out your sugaring +tin and brush ready for action. Take your course along some +definite track that you are sure to remember, painting vertical strips +of sugar, about a foot long, on the trunks of trees or on palings, +and hanging strips of rag that have just been steeped in the sugar +on the branches of small trees and shrubs where you do not find +good surfaces for the brush.</p> + +<p>After satisfying yourself concerning the amount of sugar distributed, +retrace your steps, examining every patch of sugar as you +go. It will not be long before signs of life appear. Earwigs, spiders, +centipedes and slugs will soon search out the luscious feast, but +unless the time and the locality are ill chosen, the lantern will soon +reveal a goodly number of moths, with eyes glaring like little balls +of fire, greedily devouring the bounteous repast. These will consist +chiefly of <i>Noctuæ</i>, but <i>Sphinges</i>, <i>Geometræ</i> and numerous small +species also join the company.</p> + +<p>Some will exhibit a restless disposition, either darting off before +you make a close approach, or keeping their wings in rapid vibration +as if to be fully prepared for a hasty retreat when occasion demands. +These must receive your attention first; and, having secured them, +proceed to box as many as you require of the more lazy and +gluttonous species.</p> + +<p>As a rule, moths thus engaged are easily pill-boxed, but the +livelier ones will not submit to such treatment without attempting +to escape. The best way to secure these is either to cover them +with the opened cyanide bottle (or its substitute), and replace the +cork as soon as a favourable opportunity occurs; or to perform the +same feat with a glass-bottomed pill box.</p> + +<p>The advantage of the latter over the ordinary boxes will be<!-- Page 94 --><span class="pagenum"><a name="Page_94" id="Page_94">[Pg 94]</a></span> +seen at once. After the insect is covered, its movements can be +watched, and so a favourable opportunity can be seized for snapping +on the lid.</p> + +<p>As already stated, some moths feign death when in danger, +allowing themselves to fall in places where they are often quite safe +from capture. Others allow themselves to fall simply because they +have so gorged themselves with the intoxicating sweet that they +can no longer maintain their hold. Both these classes of sugar +seekers may easily be secured by means of a net commonly known +as the 'sugaring net.'</p> + +<div class="figleft" style="width: 300px;"> +<a name="FIG_54" id="FIG_54"></a> +<img src="images/i_111.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 54.—Frame +for the Sugaring +Net.</span> +</div> + +<p>This implement is so simple in its construction that anyone can +easily make his own. The frame may consist of two straight +wires or canes fixed in a metal <span class="lettershape">Y</span>, and the other ends joined by a +piece of strong string or catgut as shown in <a href="#FIG_54">fig. 54</a>. The net itself need +not be deep. As soon as you reach a tree where moths are feeding +on the sugar, press the string of the net against +the bark just below them. The string at once +assumes the form of the trunk so well that you +may be sure of every insect that falls while you +are boxing.</p> + +<p>For this work both hands must be free, and +this is easily managed in spite of the number of +appliances called into service. The lantern is +slung round your neck and secured by a strap +round the chest. The 'sugaring net' has a very +short stick, and just while you are engaged in +boxing specimens, it may be gently held against the trunk by a +slight pressure of the body. But such precautions as these are +necessary only when the night worker is out alone. There are +many circumstances, however, that render the work of two or more +in company much more enjoyable than that of a single-handed +entomologist. The labours are considerably expedited where a +division enables each one of the night ramblers to take a particular +portion of the work; and if there is such a person as a nervous +entomologist, that individual should on no account go a sugaring in +lonely spots on dark nights. Every rustling leaf gives such a one +a start; all footsteps are those of approaching disturbers of the +peace; and when at last the invisible landowner or his keeper, +attracted by the mysterious movements of the lamp, greets him +with his gruff 'What's your business here?' then for the moment +he forgets his enchanting hobby and wishes he were safely at home.<!-- Page 95 --><span class="pagenum"><a name="Page_95" id="Page_95">[Pg 95]</a></span></p> + +<p>It is certainly advisable to take a friend, whether an entomologist +or not, on such expeditions; and if you intend working on private +grounds, always make previous arrangements with the property +owner, that you may fear no foes and dread no surprises; for a +sugarer is far more sure of success in his work if he keeps a cool +head and has nothing to think about for the time being but his +moths and his boxes.</p> + +<p>A few hours at this interesting employment pass away very +rapidly, and when midnight arrives there is often no great desire to +leave off, especially when it is known that some species of moths +are not very busy till very late at night. Still it is not advisable +to surfeit oneself with even the sweets of life. Perhaps it is better +as a rule to work the early species only on one night, and reserve +another for the later ones. The searchings are then always carried +on with vigour throughout, and the labours that are thus never +made laborious ever retain their attractiveness in the future.</p> + +<p>It has often been observed that, when sugaring has been carried +on for a few successive nights in the same locality, the success is +greater each night than on the one preceding it. Hence it is a +common practice to work a chosen 'run' for two, three, or more +nights in succession; and some collectors even go so far as to lay on +the bait for a night or two previous to starting work. For the same +reason it is often advisable to continue the use of a fairly productive +beat rather than to wander in search of a new one.</p> + +<p>In the neighbourhood of large towns one may often meet with +patches of sugared bark that mark the course and extent of a +brother entomologist's beat, and such are valuable to an inexperienced +amateur in that they give him some idea of the nature of +the localities that are chosen by more expert collectors. But it +must be remembered that each entomologist has a moral right to a +run he has baited, and that it is considered ungentlemanly, if not +unjust, to take insects from sugar laid by another. I have sometimes +seen cards, bearing the names of the collectors and the date of +working, tacked on to baited trees and fences, thus establishing +their temporary exclusive rights to the use of their runs. Such +precautions are not necessary in large tracts of forest land, where +the choice of runs is practically unlimited.</p> + +<p>There are two other modes of capture available to the moth +collector—the use of decoy females, and the employment of 'sugar +traps'—and both these may be used on the sugaring run, or at other +times either in the woods or in your own garden.<!-- Page 96 --><span class="pagenum"><a name="Page_96" id="Page_96">[Pg 96]</a></span></p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_55" id="FIG_55"></a><img src="images/i_113a.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 55.—Cage for +Decoy Females.</span> +</div> + +<div class="figright" style="width: 300px;"> +<a name="FIG_56" id="FIG_56"></a><img src="images/i_113b.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 56.—A Sugar +Trap.</span> +</div> + +<p>The wonderful acuteness of the sense by which the males of +certain species are enabled to seek out the females has already been +alluded to, and the possession of a suitable decoy will often bring +you a number of beautiful admirers without the least trouble, except +that taken in securing the decoy and preparing her temporary abode. +It is absolutely necessary that the female moth be one that has +recently emerged, and consequently you had better secure her in +one of her earlier stages, either by previous rearing or by collecting +the pupæ.</p> + +<p>A little cage composed of a framework of wire covered with gauze +must now be made. Perhaps the simplest pattern is that illustrated. +Here the gauze is attached to two wire rings, only a few inches in +diameter, and suspended by a string. Such a cage answers every +purpose in the field, and has the advantage of folding into an +exceedingly small space when not in use. It may be suspended in +your garden or taken into the field whenever you have a suitable +decoy at your disposal.</p> + +<p>The sugar trap may be of much the same pattern as that in +which a light is used, but if intended for field work it should be of a +convenient size for portability. A lighter and far more convenient +form may be constructed as follows:</p> + +<p>Procure a large cylindrical tin box, and cut a circular piece of +perforated zinc just small enough to drop into it. Then make two +wire rings, one a <i>little larger</i> than the top of the tin, and the other +only about an inch in diameter. Next make a conical net of leno, +open at both ends, and of such a size that the two rings may form +the frames of its two extremities. When the trap is required for<!-- Page 97 --><span class="pagenum"><a name="Page_97" id="Page_97">[Pg 97]</a></span> +use, cut a circular piece of flannel or other absorbent, steep it in +sugar that has just been flavoured with rum, and place it in the +bottom of the tin. Then place a few pebbles of equal size around +the sides to support the zinc partition, drop in the partition, and +then allow the net to hang on the rim as shown in the sketch.</p> + +<p>This arrangement will explain itself. The moths, attracted by +the sweet perfume, flutter about in the net till at last they find their +way through the small ring. Once in, they make further attempts +to reach the sugar; and, at last, finding all efforts fruitless, +and, like Paddy at the fair, not being able to discover the 'entrance +out,' they finally settle down in a disappointed mood awaiting your +pleasure.</p> + +<p>Perhaps another word of explanation is necessary here. Why +not allow the poor creatures to reach the sugar that attracted them +to the spot? The reason is this. They sometimes gorge themselves +to such an extent that their bodies, dilated to the fullest capacity +with syrup, are a bit troublesome when the insects are placed in the +cabinet. It is therefore advisable to see that the zinc is so far above +the sugar that the moths are unable to reach the latter by thrusting +their extended proboscides through the perforations. A few dead +leaves scattered on the zinc is also a useful addition, since it affords +shelter to such of the insects as prefer it.</p> + +<p>This is a very useful trap to keep in one's garden throughout the +season. It may not attract large numbers, but it has the advantage +that it requires no watching. It is simply necessary to set it at +dusk, and remove the captives in the morning or at your leisure.</p> + + + +<hr /> +<p><!-- Page 98 --><span class="pagenum"><a name="Page_98" id="Page_98">[Pg 98]</a></span></p> +<h3><a name="CHAPTER_VII" id="CHAPTER_VII"></a>CHAPTER VII +<br /> +<i>COLLECTING OVA, LARVÆ, AND PUPÆ</i></h3> + + +<p>We have already observed that insects should, as a rule, be set as +soon as possible after their capture; and it would therefore seem +that this is the proper place for instructions in this part of the work. +But it so happens that butterflies and moths are to be obtained by +means other than those already described, and we shall therefore +consider these previous to the study of the various processes +connected with the setting and preserving of our specimens.</p> + +<p>Were we to confine our attention to the capture of the perfect +forms only, our knowledge of the <i>Lepidoptera</i> would be scanty +indeed, for we should then be ignorant of the earlier stages of the +creatures' lives, and have no opportunity of witnessing the wonderful +transformations through which they have to pass.</p> + +<p>Such an imperfect acquaintance with butterflies and moths will, +I hope, not satisfy the readers of these pages; so it is intended, in +the next two chapters, to give a little assistance to those who would +like to know how to set to work at the collection of their eggs and +larvæ, how to search for the pupæ, and how to rear the insects +from the stage at which they are acquired till they finally emerge +in the perfect form.</p> + +<p>These portions of an entomologist's work certainly take up a +great deal of his time, and also require much patience and perseverance; +but the advantages derived cannot be over-estimated, for +in addition to the knowledge gained of the early stages of insect +life, this kind of work will enable him to place in his cabinet a +number of gems he would otherwise have not and probably know +not. Occasionally a prize may be obtained in the form of a cluster +of eggs (<i>ova</i>) of a rare species, in many instances the larvæ are to +be obtained with comparative ease, while the perfect insects of the +same species are not often seen or not easily captured, and many a<!-- Page 99 --><span class="pagenum"><a name="Page_99" id="Page_99">[Pg 99]</a></span> +rare pupa has been dug out of its hiding place during a season +when the entomologist had but little other work to occupy his time.</p> + +<p>These and other similar subjects we shall now consider in turn.</p> + + +<h4><i>Collecting Ova</i></h4> + +<p>The collection of ova may be carried on more or less throughout +the year. A number of moths are out in February, and even +in January if the weather is mild. These soon lay their eggs, +which are hatched about the time that the buds of the food plant +are breaking. From this time till late in the summer the ova of +various species are being deposited, the average period from laying +to hatching being from two to three weeks. Then, during the +autumn, when the leaves of food plants are turning brown and +crisp, ova are still being laid, but these remain unchanged till the +new buds of the following spring are bursting.</p> + +<p>Of course if you intend searching for the ova of particular species +you must previously ascertain the favourite haunts of those species, +become acquainted with their food plants, and also with the season +or seasons during which the eggs are laid. But the few following +hints will suffice as general instructions for the search.</p> + +<p>In nearly all cases we must expect to find ova on the food plants +of the respective species, but at times, especially with certain +moths, we may come across them in the most unlikely spots. +Thus, it sometimes happens that a moth settles on a street lamp, +and lays her eggs on the framework round the glass, or even on +the glass itself. The same thing may take place on the sash or +glass of a brightly lighted window.</p> + +<p>Such occurrences, however, we must regard as accidental and +comparatively rare, and therefore we confine our searchings for ova +to the food plants of the species we require.</p> + +<p>As a rule the under sides of the leaves will yield the most, but +we have already noticed (<a href="#Page_18">page 18</a>) that some moths leave their eggs +exposed on the upper surface. Again, some larvæ feed on flowers +and seeds and fruit, and the eggs of such are deposited on these +parts. Those insects which feed on the leaves of shrubs and trees +often lay their eggs on trunks, branches and twigs. Sometimes +these are laid singly, sometimes in dense clusters; and it is not +unusual to find them arranged in rings or spirals with great regularity. +When examining the trunks of trees for ova it is necessary +to look well into the crevices of the bark, for some insects take<!-- Page 100 --><span class="pagenum"><a name="Page_100" id="Page_100">[Pg 100]</a></span> +particular care to lay them in deep sheltered chinks; but others +take no such precautions, and deposit them on exposed ridges or +plain surfaces where they are easily discovered.</p> + +<p>One difficulty of the ova collector lies in the fact that many +insects lay on the upper branches of large trees. Of course a search +for these is out of the question; but in places where the trees have +been cut down a few years previously, and where a consequent +undergrowth has developed, there are considerable chances of +success with these species. Young saplings of trees often yield +well, especially in places where tall trees of the same species are +absent. It may be mentioned, too, that some moths (<a href="#Page_294">page 294</a>) +actually lay their eggs beneath the surface of water, depositing +them on the under surfaces of floating pond weeds; and others +(<a href="#Page_298">page 298</a>) even enter the nests of wasps and bees for the same purpose. +It is clear, then, from these few remarks, that the work of +an ambitious collector of insects' eggs is by no means a monotonous +task; for his employment takes him into the meadows and +woods, leads him to the banks of ponds, and even compels him to +tear down banks and hedges for the nests of <i>Hymenoptera</i> at the +risk of a sting or two.</p> + +<p>One of the most productive sources of eggs is undoubtedly the +possession of captured females. When you are out netting butterflies +you often see a female that is evidently engaged in her +matronly duties. Instead of seeking food from the various flowers +in her path, she pays attention only to the foliage, looking out a +suitable leaf on which to deposit her eggs. Should you meet with +an insect thus engaged which you would like to rear at home, or of +which you would like to know the egg, secure it in a perforated +pill box with a leaf of the proper plant; and it will often supply +you with abundance of eggs for your purpose, in many cases depositing +them in the box before you arrive home. The eggs of +numerous species of moths are also to be easily obtained from +captured females.</p> + +<p>Some insects do not seem inclined to deposit their eggs in captivity +as freely as when at large, and in order to induce them to do +so we must, as far as possible, put them in their natural conditions. +Let them have plenty of room, and supply them with fresh twigs +of their food plants, kept green by standing them in vessels of +water. It is also advisable, supposing you are not well acquainted +with the dispositions of the species you have, to keep a portion of the +box well shaded from direct sunlight, and allow another part to be<!-- Page 101 --><span class="pagenum"><a name="Page_101" id="Page_101">[Pg 101]</a></span> +as bright as possible; for some species will not lay in a bright light, +while others will not do so without it.</p> + +<p>Again, while some deposit their eggs within a few hours of +quitting the pupa case, others do not lay for several days. With +regard to the latter, it is frequently necessary to feed them while +in captivity, by placing in the box a piece of rag or sponge that has +been dipped in honey or syrup.</p> + +<p>Each batch of ova should be carefully examined with a view to +knowing them by sight on a future occasion. A sketch should be +made in your note book, showing every detail that you can make +out with the aid of a good lens. Then observations concerning the +season, colour of the eggs, the situation in which deposited, arrangement, +and any other useful particulars, should be entered.</p> + +<p>In the next chapter some hints will be given concerning the +management of ova and the rearing of the larvæ from the time of +hatching.</p> + + +<h4><i>Collecting Larvæ</i></h4> + +<p>This occupation is generally far more productive to the +entomologist than searching for ova. The latter are very small, +usually well concealed, and to be detected only by a careful +scrutinising use of the eyes; but the superior size of the larvæ, +the frequent bright colouring, and the fact that they are easily +beaten from their hold, render the searchings of their hunters +comparatively easy and fruitful.</p> + +<p>Before setting out on a larva-hunting expedition, there are a few +requisites to prepare. These include not only the implements for +your work in the field, but also the cages in which you intend to +rear your little captives. The latter are described a little later on +under the head 'Rearing Lepidoptera,' and the former we will now +briefly summarise.</p> + +<p>The outfit must consist of a quantity of suitable boxes, a stout +hooked stick, a strong net, and a white material to place under the +herbage while you are 'beating.'</p> + +<p>'Larva boxes' are usually made of zinc, and have little sliding +doors in the lids, so that the lids need not be removed while out of +doors after the fragment of the required food plant has been +inserted. Such boxes are not by any means essential. Small tin +boxes will answer all purposes nearly as well, providing a number +of small holes be made in them for the admission of air. Chip +boxes are also fairly satisfactory, but these also should be perforated.<!-- Page 102 --><span class="pagenum"><a name="Page_102" id="Page_102">[Pg 102]</a></span> +The best way to do this is to push a red-hot iron wire +through the chip, making about half a dozen small holes in each +box. This method will give you clean holes of a uniform size +without otherwise injuring the boxes.</p> + +<p>Metal boxes possess the advantage that they keep the food +plants moist for a long time, while chip boxes allow them to dry +rather rapidly. Yet there are some larvæ that do far better in the +latter, since such a quantity of moisture exudes through their skins +that they soon become uncomfortably wet if their apartment is not +well ventilated. Under these circumstances perhaps it is better to +take a supply of both, so that changes may be made as found +necessary.</p> + +<p>One grave objection to chip boxes, however, is the weakness of +the material. They are easily crushed by pressure, and a bottom +or a top disc of wood often falls out; but this is easily overcome by +gluing narrow strips of calico round the top and bottom edges. +Chip boxes should always be treated in this way, and they will +then last five or six times as long.</p> + +<p>Your supply of boxes should always include one large one of +metal in which to bring home a supply of food for the larvæ. If +you have a botanist's vasculum, by all means take it, for nothing +can serve this purpose better. If not, any rather large square tin +box will do, and this may be carried in your satchel, or a couple of +hooks may be soldered to it so that a leather strap can be fixed for +slinging it over your shoulder.</p> + +<p>The net required is that commonly known as the 'sweep net.' +It must be very strong, for it has to submit to rather rough usage. +The frame must be made of thick wire; and the bag, which need +not be more than a foot deep, should be of strong calico or holland.</p> + +<p>Now with regard to the white material previously mentioned. +This may be a square of calico, hemmed round the edges. Nothing +is more convenient than this, as it occupies but little room in the +pocket when not in use, if neatly folded. The material need not +be thick, but the larger it is the better. Many prefer a white +umbrella or an ordinary umbrella with a white lining, but as this +is only a matter of taste and convenience you must decide for yourself +as to which you will use.</p> + +<p>If your field of operations is only a little way from your head +quarters, and quantity of luggage therefore not a serious consideration, +you may provide yourself with a heavy mallet, loaded if +necessary with a pound or two of lead. This will prove very useful<!-- Page 103 --><span class="pagenum"><a name="Page_103" id="Page_103">[Pg 103]</a></span> +in shaking larvæ from trees and large branches. Lastly, take a +pencil and a note book or writing paper for your observations in +the field.</p> + +<p>Now for the choice of the season. Larvæ are to be found all +the year round. Early in the spring, as soon as the buds are +bursting, some break out of the eggs recently laid by the moths +that appear in February and March. Later on, during April and +May, a host of both butterflies and moths are busy arranging for +their broods. Then, throughout the whole of the summer, thousands +of caterpillars of all sorts and sizes are to be met with everywhere. +And finally, during the bleak winter months, you may +amuse yourself by digging the hybernators out of their hiding +places where they rest themselves till the spring sun again calls them +out to refresh them with the young and tender leaves of a new +year. Thus, unless you are merely intending to search out certain +species you happen to require, there is not much difficulty in +settling on the season.</p> + +<p>The day selected should be dry, for your work lies among the +herbage of banks, meadows, and woods, and nothing is more unpleasant +than wading through a wet and dense vegetation, or beating +down on yourself a shower of large drops from the branches of +trees and shrubs.</p> + +<p>Having reached the hunting ground, the first thing to do is to +look out for <i>signs</i> of the presence of larvæ rather than for the +larvæ themselves. Healthy vegetation with sound leaves must be +passed by as untenanted; but the presence of partly eaten foliage +immediately arouses suspicion.</p> + +<p>A little experience will soon enable you to distinguish between +the ravages of larvæ and of slugs, snails, wasps, &c. Some of +the smaller larvæ certainly eat out clean holes like those cut by +<i>Hymenopterous</i> insects, but as a rule they bite away at the edges, +leaving the midrib and the larger veins standing out almost naked.</p> + +<p>By looking well into the edges of the eaten leaves, it is easy to +see whether the marauders have been recently at work. If they +are dried up and discoloured, it is not of much use to search; but if +still green and moist, you may feel almost sure that the hungry +larvæ are not far off.</p> + +<p>In this case you will carefully turn over the leaves to examine +the under sides, and also the leaf stalks and branches or stems; +but you must be prepared for all kinds of protective mimicry. +Little green caterpillars will be seen lying on the midrib or<!-- Page 104 --><span class="pagenum"><a name="Page_104" id="Page_104">[Pg 104]</a></span> +veins, so straight and so still that they are scarcely perceptible. +Others are snugly tucked in a depression of a leaf with the same +result. Then we must also be prepared for the artful little tricks +of the larvæ of <i>Geometræ</i> (<a href="#Page_268">p. 268</a>), by which they imitate stalks +and twigs so closely that a sharp eye is necessary to discriminate +between the two.</p> + +<p>While thus searching we may meet with the cast skin of a caterpillar. +This gives us fresh hopes, and so we continue our careful +examination. At last, on grasping a leaf in order to turn it over for +inspection, we feel something hairy or something soft and smooth. +But lo! it is gone. It is one of those numerous caterpillars that +feign death and drop to the ground on the slightest sign of danger. +We search below for it, but the density of the vegetation renders +this hopeless, and we are just about to start off in search of a more +productive locality when we espy a quantity of the excrement of +larvæ lying on a little bare patch of ground close by. This gives +us a new idea. Here is another indication of the presence of the +creatures we require, one that we can put into practice; and by-and-by +we learn that in many cases this is really the surest sign +of their whereabouts.</p> + +<p>We look at these little pellets of excrement, and gain at once +some idea of the <i>size</i> of the larvæ that produce them. Then we +observe whether they are fresh and moist, or dry and stale. If the +latter, it is not of much use to examine the leaves above; but if +otherwise, there is little doubt of our meeting with larvæ, as the +present position they occupy is so truly marked. The leaves just +over them are carefully examined, either by turning them over as +before described, or, if the height of the foliage admits of it, +by placing our heads below and looking upward.</p> + +<p>If we find that the larvæ are some of those that endeavour to +escape by feigning death and allowing themselves to drop at the +slightest disturbance, the net is always kept beneath the leaves we +are touching in order to intercept them in their downward journey.</p> + +<p>Continuing the search, we meet with leaves that are rolled up +and bound with silk threads, and others that are drawn together +and similarly bound. These are carefully uncurled and pulled +asunder with the result that active little larvæ are exposed to view, +or, it may be, pupæ are discovered. In some cases flowers are +drawn together in just the same way, and an examination reveals +one or more of the species that prefer petals and other parts of +flowers to the green leaves.<!-- Page 105 --><span class="pagenum"><a name="Page_105" id="Page_105">[Pg 105]</a></span></p> + +<p>Silken threads always arouse our suspicions. These may be seen +lying on the surfaces of leaves, and passing from one leaf to another, +or they may be hanging perpendicularly from the branches of trees +above. In the latter case a larva may be frequently seen on the +lower extremity of the fibre, swinging gently in the breeze, and, +should we require it, we have only to place the open box below for +its reception.</p> + +<p>Hawthorn and other trees are sometimes seen almost devoid of +leaves, nearly every bit of green having been greedily devoured by +a host of small larvæ. In such cases we often meet with dense +clusters of silk fibres that may easily be mistaken for spiders' nests. +But when we look more closely into the structure we observe that +we have discovered instead nests of gregarious larvæ, such a large +number being in each little community that the deplorable appearance +of the tree is at once explained.</p> + +<p>A little farther on we meet with a sickly-looking plant in the +midst of a number of flourishing individuals of the same species, +and stop to make inquiries into the cause of this strange occurrence. +Is it due to a poorness of the soil? No, this cannot be the case; +for intermingled with its roots are those of its flourishing companions. +We pluck a stunted and half-shrivelled leaf and examine +it. At first we do not notice the cause of its peculiar condition; +but, holding it up to the light, and looking <i>through</i> it, we see a +number of little galleries that have been eaten out of its internal +soft substance, leaving the thin skin (<i>epidermis</i>) almost entirely +intact. But nothing more is to be seen. Another leaf is examined +in exactly the same way; and here we see the little destroyer, lying +motionless in its burrow till a gentle pressure applied against it +from outside causes it to wriggle along its narrow passage. This is +the larva of one of the little leaf miners mentioned again on +<a href="#Page_303">page 303</a>.</p> + +<p>Reaching a little marshy spot we see a number of water-loving +reeds, most of them beautifully green and in a flourishing condition, +but here and there in their midst is a poor stunted specimen—another +result of the ravages of the larvæ of one or more moths. +An examination of the blades reveals nothing; but on splitting +open the stalk we discover some larvæ that have already devoured +a quantity of the internal pith, and thus endangered the life of the +plant. On inspecting other similar reeds we are at first puzzled as +to how the larvæ could get inside the stems without damaging the +outer portion; but at last we see in each one a little discoloured<!-- Page 106 --><span class="pagenum"><a name="Page_106" id="Page_106">[Pg 106]</a></span> +hole that was eaten out by the young caterpillar just after its escape +from the egg. Once within the reed, it found a plentiful supply of +food, and there grew at the expense of the plant without doing any +further external damage save by causing a stunted growth.</p> + +<p>It may be that the stem eaters we have found are just about +full grown. If so we examine a number of the stems with a hope +that we may find one or two that are just about to change to the +chrysalis state, or even a pupa already formed. By this means we +may secure one of the perfect insects without the necessity of feeding +larvæ at home. Such a consideration becomes a most important +one when it happens that the required food plant is one that cannot +be easily obtained.</p> + +<p>Close by the reeds is another water-loving plant in the form of +an old willow tree. This is always an attractive object to the +entomologist, so it comes in for a share of our inspection. On its +leaves we may find several species of the larvæ of <i>Lepidoptera</i>, +including those of some of our largest insects. But a strange feature +catches our eyes as we happen to glance at the bark of the tree. +Here we see a few holes of different sizes, about which are a number +of little fragments of wood that remind us of 'sawdust;' and, +examining the ground below, we see quite a little heap of this +dust, looking just as if a carpenter had been at work on the spot.</p> + +<p>This is not the effect of a saw, however; it is a sure sign of the +ravages of wood-eating larvæ (<a href="#Page_224">p. 224</a>), whose powerful jaws gain +them admittance into the very hearts of trees, and the application +of the nose to one of the larger holes leaves no doubt of the presence +of the large and beautiful caterpillar of the Goat Moth +(<a href="#Page_224">p. 224</a>).</p> + +<p>If we require any of these wood-eaters, either for rearing or for +preservation, we must be prepared for a little rather heavy work. +A strong pocket knife is not sufficient, but with a good chisel the +wood can be gradually cut away, and the galleries traced, till at +last we come to the larvæ snugly resting in their burrows.</p> + +<p>It often happens that the tree thus tenanted is half decayed, and +consequently the work is rendered much easier. Also, while tearing +away the wood, we often meet with a number of cocoons that +have been constructed by the caterpillars for their winter quarters, +or as a resting place while undergoing their transformations. These +are composed of the wood dust bound together by strong silk fibres, +and are often in such a good state of preservation that they form +useful illustrations for the cabinet.<!-- Page 107 --><span class="pagenum"><a name="Page_107" id="Page_107">[Pg 107]</a></span></p> + +<p>As further aids to larvæ searching we may mention that many +species—chiefly of the <i>Noctuæ</i>—hide under the surface of the ground +or among dense and low herbage during the day, and come out to +feed only by night; that many others feed on roots, and are therefore +seldom seen above the surface of the soil; also that a good +number burrow into fruits, in the interior of which they spend the +whole of their larval stage. The best way to secure the latter is to +examine the 'windfalls' that lie scattered on orchard lands, for it +is a well-known fact that the fruits that are infested with larvæ +generally fall earlier than others—a result that must be attributed +to the damaging work of the larvæ themselves.</p> + +<p>All the larvæ collected should be carefully boxed at once, a +separate compartment being used for each species, and a few fragments +of the food plant being introduced in each case. It is also a +good plan to have each box previously lined with moss as a further +addition to the comfort of the captives. Without such a precaution +some of the more delicate species are liable to injury during their +transmission from field to home.</p> + +<p>Hitherto we have obtained our larvæ by <i>searching</i> only, but +there are times and occasions when our boxes may be far more +rapidly filled by methods that are not such a tax on our time and +patience. Suppose, for instance, that we reach a bush, the mutilated +leaves of which seem to show that larvæ are present on its +branches. We spread our white cloth or open out the white-lined +umbrella just under a selected branch, and then tap that +branch very smartly with our stick.</p> + +<p>Down comes a host of living creatures! Spiders, larvæ, beetles, +aphides, earwigs, and what not, struggling and running about on +our white fabric in all directions, and all mingled with bits of stick, +leaves, and fragments of all kinds. We leave the cloth or the umbrella, +as the case may be, quite still for a few seconds to allow all +the living creatures to get a good foothold, and then, raising it into +a vertical position, allow all the rubbish to drop off.</p> + +<p>We can now put the cloth down again, and select as many of +the larvæ as we require, giving our first attention to the nimble +runners and loopers that are already near the edge and just on the +point of making their escape. This productive method of larva +hunting is known as 'beating,' and is particularly applicable to tall +herbs and the lower branches of trees and shrubs.</p> + +<p>The same principle may be employed in the case of branches +that are quite out of the reach of the stick, but the blows are here<!-- Page 108 --><span class="pagenum"><a name="Page_108" id="Page_108">[Pg 108]</a></span> +applied to the trunk, a mallet or some other rather heavy implement +taking the place of the stick.</p> + +<p>Another splendid method of securing larvæ where mere searching +would be tedious and unproductive, lies in the use of the sweep +net described on <a href="#Page_102">page 102</a>. This implement comes into service in +waste places that are covered with rank vegetation, in clover and +hayfields, and in all spots covered with low herbs.</p> + +<p>Walking among the vegetation, the net is swept right and left +before you, and the contents examined at frequent intervals. It is +advisable to work the different species of herbs separately as far as +possible, otherwise there may be some difficulty in the determination +of the food plants of the mixed larvæ that the net will +contain. If, however, this plan is impracticable, you may save +time by turning out all the 'sweepings' into one large box, leaving +the sorting to be done at home in leisure hours.</p> + + +<h4><i>Collecting Pupæ</i></h4> + +<p>We have seen that ova and larvæ may be obtained in greater or +less abundance at all times of the year, so variable are the seasons +of the different butterflies and moths. The same remark applies +equally well to pupæ; but so many of the Lepidoptera spend the +winter months in the chrysalis state that this period may be +regarded as the harvest time of the pupa hunter.</p> + +<p>A large number of caterpillars undergo their change to the +quiescent state during the months of August and September, and, +of course, remain in this state until the warm days of the following +spring or summer. And as insects even in the pupal stage have a +number of enemies and dangers to contend with, it is advisable to +start your search for them as soon as possible after they have +changed.</p> + +<p>If you set your mind on searching for particular species, you +should endeavour to ascertain the <i>usual</i> time at which such species +pupate; make any necessary allowances for the forwardness or +backwardness of the season, and then allow a week or two for the +change to be completed, for insects should never be disturbed at +times when their metamorphoses are in progress.</p> + +<p>For general pupa hunting the best season is undoubtedly from +the end of August to the end of October, but there is no reason +why the work should not be carried on throughout the winter. If, +however, you continue your work so late, you must not expect<!-- Page 109 --><span class="pagenum"><a name="Page_109" id="Page_109">[Pg 109]</a></span> +nearly as much success as time advances. You must remember +that entomologists are not the only pupa hunters. Many hungry +birds are always on the look-out for insects, and seem to enjoy +them equally well in all their stages. Those that hybernate on or +under the ground are liable to fall a prey to moles and beetles. In +addition to these dangers, all pupæ are subject to the effects of +extreme cold, dampness, or floods.</p> + +<p>As regards the choice of a day, very little need be said. Any +day that is sufficiently genial for yourself will do for your work, +except that periods of hard frost render the ground too hard for +digging—the most profitable part of the pupa hunter's task.</p> + +<p>The apparatus required is extremely simple: A satchel or +large pockets full of small metal or chip boxes, a small garden +trowel, and a strong chisel.</p> + +<p>If metal boxes are used they should be perforated; in fact, +nothing is better than the ordinary larva boxes of the dealers. +All the boxes, of whatever kind, should be lined with moss previous +to starting work.</p> + +<p>The trowel and chisel do not pack well with a number of small +boxes, therefore it is a good plan to fix them in a couple of +leather sheaths attached to your belt. In this position they are far +more handy for use, and the boxes are also in less danger of being +crushed or damaged, as they probably would be if in contact with +hard and heavy tools.</p> + +<p>A note book is also a valuable addition to your outfit, as it +enables you to make memoranda concerning the trees and localities +from which you obtain your pupæ.</p> + +<p>The best localities for pupa hunting are clearings in woods, +parks with numerous large timber trees, and meadows in which +large isolated trees are scattered; and the best trees include willows, +poplars, oaks, beeches, birches, elms, and hawthorns.</p> + +<p>The best thing you can do on arriving at the selected hunting +ground is to make at once for isolated trees of large size, and work +each one as follows:</p> + +<p>First examine well the crevices of the bark, for many caterpillars +descend the tree to within a short distance of the ground, +and then seek out a snug little crevice in which to spend the +winter, often protecting themselves with silken cocoons, or constructing +a neat little shelter of gnawed fragments of the wood +cemented together.</p> + +<p>If there is any loose bark, very carefully force it out with your<!-- Page 110 --><span class="pagenum"><a name="Page_110" id="Page_110">[Pg 110]</a></span> +chisel, and examine both its inner surface and the wood from which +it was removed. The wood thus exposed may reveal openings +of the galleries of wood-eating larvæ, in which case, unless the +material is too hard to be broken up with the chisel, you may be +able to trace out a few pupæ. Where these exist, they are usually +to be found very near the entrance, sometimes even protruding +slightly from the opening, for the larvæ generally place themselves +in this position of easy escape when about to change.</p> + +<p>Next give your attention to the moss, if any, covering the lower +portion of the trunk. This affords a very favourite shelter to +many species. Tear it off very carefully, beginning at the top, and +watch for loose pupæ and cocoons as you do so. Then hold the +clumps you have removed over a patch of bare ground or over a +spread handkerchief, and pull it to pieces, in order that any pupæ +it contains may fall out; also examine the fragments carefully for +others that may remain attached.</p> + +<p>This done, the surface of the ground must be examined. +Remove all dead leaves, and watch for pupæ that may be sheltered +beneath them. If any loose stones lie on the ground, turn them +over. Search well into the angles between the roots, and if there +are any holes or hollows beneath them or in the trunk itself, pull +out all loose matter within, and <i>feel</i> gently above and around for +cocoons.</p> + +<p>After all loose matter has been removed, there still remains the +soil for examination. If this is very hard and clayey, it is probably +useless to carry the search any farther; also if very wet you +need not expect much; but if comparatively dry and friable there +are more hopes of success.</p> + +<p>As a general rule the north and east sides of the trunk are +drier than those which are exposed to the heavy rains brought +by the south and south-west winds, and are consequently more +favoured by larvæ that are seeking a resting place for the winter.</p> + +<p>Most larvæ seek shelter in the angles between the roots of the +trees on which they fed, but a few species seem to prefer the +edges rather than the corners; and in cases where no such angles +are formed at the surface, you will do well to examine the earth +and turf all round the trunk; but it is generally useless to extend +the search more than a few inches from the tree.</p> + +<p>After having searched every available nook and corner as far +as possible without digging, thrust the trowel obliquely into the +soil a few inches from the tree, turn over the sod, and then examine<!-- Page 111 --><span class="pagenum"><a name="Page_111" id="Page_111">[Pg 111]</a></span> +the spot from which it was removed. Now give your attention +to the sod itself. If loose and friable, break it up gently, +keeping a sharp eye for falling pupæ, and also for earthen cocoons +that are easily mistaken for little lumps of soil.</p> + +<p>If the soil is held together by roots, it must be pulled to pieces, +and the fragments shaken over a bare piece of ground where the +fall of a pupa or cocoon could be easily seen; and if you have +removed a grassy turf, it will be necessary to look between the bases +of the blades as well as among the roots.</p> + +<p>In this way you may search round tree after tree, wherever the +soil is of such a character as to allow of the admittance and shelter +of larvæ. But the variability of your success will be quite beyond +your comprehension. Sometimes you will sight a grand old oak +with the most favourable anticipations, and consider yourself quite +certain of a good find when you discover, on a nearer approach, +the liberal coating of moss that clothes its trunk and the dry sandy +soil at its foot; and yet the most careful search ends in nothing +but disappointment. At other times you try your luck at tree +after tree without ever seeing a single pupa or even a cast-off case, +and then, when just on the point of despairing, you search round +another that is apparently much less promising, and, to your great +surprise and delight, a dozen or two are turned out in a few minutes. +Such an occurrence as this is not at all uncommon, and cannot be +satisfactorily explained, but we must take things as they come and +make the best of them, remembering that pupa searching is one of +the best of all entomological operations wherewith to test one's +perseverance and patience.</p> + +<p>It may be mentioned, in conclusion, that the pupæ of <i>Lepidoptera</i> +are never to be found far below the surface of the soil. Generally +they exist, if buried at all, only an inch or two down, and very +rarely at a greater depth than four inches.</p> + +<p>In our next chapter we shall learn how to rear the perfect +insects from the earlier stages we have been considering.</p> + + + +<hr /> +<p><!-- Page 112 --><span class="pagenum"><a name="Page_112" id="Page_112">[Pg 112]</a></span></p> +<h3>CHAPTER VIII +<br /> +<i>REARING LEPIDOPTERA</i></h3> + + +<h4><i>Management of Ova</i></h4> + +<p>In the management of insects in all stages the strictest attention +must always be paid to one general rule on which the success of +the work almost entirely depends; and that is—keep every specimen +as far as possible under the same conditions as those in which you +find it in nature.</p> + +<p>Applying this principle to ova, we store them in airy and light +places, protected from the direct rays of the sun, and avoid handling +and rough treatment of any kind. It is also advisable in most +cases to maintain a slight amount of dampness corresponding with +that of the open air at the particular season of the year.</p> + +<p>They do not require much space, and it is certainly desirable +not to give much, otherwise the newly hatched larvæ, when their +time arrives, will actively wander all round their premises in search +of food, and give you no end of trouble in gathering them up.</p> + +<p>Chip boxes are, as a rule, very good and very convenient +receptacles for ova. After placing the eggs in these, cover them +over with very fine muslin, held in place by elastic bands; and label +each as far as you can with the name of the species contained, and +other particulars worth remembering. The boxes may then be +put in front of a window facing north, or in any situation within +or out of doors where rain and sun cannot reach them. A greenhouse +is an admirable place in which to keep them, the natural +dampness of the atmosphere being apparently a considerable +assistance to the tiny larvæ just as they are striving to escape from +their shell.</p> + +<p>Whatever place is selected, it is absolutely necessary that the +ova be carefully watched, so that each brood may be supplied with +the required food plant within a few hours of quitting the shells.<!-- Page 113 --><span class="pagenum"><a name="Page_113" id="Page_113">[Pg 113]</a></span></p> + +<p>When ova are kept in a warm room, very great inconvenience +and even loss is sometimes caused by the appearance of larvæ before +the necessary food plant shows its buds. Yet, on the other hand, +it is sometimes a great gain to the entomologist to get certain +broods off early in the season, providing the food is at hand; for +in this way he can not only get some of his work over during a +slack season, but also, if he desires it, secure an additional brood; +that is, one brood more than the usual number. Thus, supposing +a certain species he is rearing is naturally double-brooded, he can, +by judicious management, secure three successive broods before the +food plant casts its last leaves.</p> + +<p>This hastening of the natural events of insect life is known as +<i>forcing</i>, and merely consists in subjecting the species concerned to +a reasonable amount of artificial heat, such as that of a room in +which a fire is always kept, or of a hothouse.</p> + +<p>It is interesting at all times to note the dates on which eggs are +laid or collected, and the times at which the young larvæ appear. +In addition to this all changes that take place in the colours or +forms of eggs should be carefully observed; for such changes will +assist you in distinguishing between fertile and sterile ova, and +also enable you to judge approximately as to the date of the +appearance of future broods.</p> + + +<h4><i>Rearing Larvæ</i></h4> + +<p>The main point in connection with the rearing of larvæ is certainly +the selection and construction of the cages or their substitutes. +For newly hatched and all very small caterpillars a small bottle +with a wide mouth makes a very fair abode. Put a layer of sand +or sifted soil in the bottom, fix in this a small twig of the food plant +or lay a few leaves on the top, and then, after the larvæ have been +introduced, cover the top with a piece of muslin, held in place by an +elastic band.</p> + +<p>The great drawback with this arrangement is the lack of any +provision for keeping the food moist and fresh, thus rendering a +change necessary at very frequent intervals; but this may be +obviated by using damp sand as a foundation for the little twig +of food plant. With this improvement, if you cover the top of the +bottle with apiece of glass, a saucer, or any impermeable substance, +you may keep the twig fresh for several days, generally until the +disappearance of the last leaf calls for a fresh supply; but it is<!-- Page 114 --><span class="pagenum"><a name="Page_114" id="Page_114">[Pg 114]</a></span> +very doubtful whether the damp atmosphere resulting from this +inclosure is not injurious to the larvæ. It certainly does not seem +to have much influence on some, but the unhealthy conditions that +result must be detrimental to the inmates. It must also be remembered +that many species require a <i>dry</i> soil in which to burrow +when about to change.</p> + +<p>When the time comes for the change of food, great care must be +taken not to injure young and small larvæ. In many cases they +need never be touched, for if a fresh twig be placed beside the stale +one, they will readily find their way to it; and to facilitate this, and +also to afford a convenient foothold to those larvæ that accidentally +fall from the twig, the layer of sand at the bottom of the bottle +should be covered with moss or cocoa-nut fibre.</p> + +<div class="figleft" style="width: 300px;"> +<a name="FIG_57" id="FIG_57"></a><img src="images/i_131a.jpg" width="300" height="379" alt="" title="" /> +<span class="caption">Fig. 57.—A Larva Glass.</span> +</div> + +<div class="figleft" style="width: 300px;"> +<a name="FIG_58" id="FIG_58"></a> +<img src="images/i_131b.jpg" width="300" height="304" alt="" title="" /> +<span class="caption">Fig. 58.—A Larva Glass.</span> +</div> + +<p>If you find it necessary to +move the larvæ yourself from +the stale food, never touch +them with your fingers, but lift them gently by means of a small +camel-hair brush. Larger larvæ need never be moved at all. They +will always search out fresh food for themselves, and the stale may +be removed after they have quitted it.</p> + +<p>For rearing larger species ordinary bottles are hardly satisfactory, +and we must either use large jars or construct cages of some kind.</p> + +<p>An ordinary bell jar such as is used for covering ferns or for +aquaria makes a very useful 'larva glass.' Place a small bottle of +water at the bottom, and then introduce sufficient dry clean sand or +sifted soil to reach up to its neck. On the top of this place a layer +of moss or cocoa-nut fibre. Next introduce the food plant, fixing it +firmly in the bottle of water, and plugging up the space between<!-- Page 115 --><span class="pagenum"><a name="Page_115" id="Page_115">[Pg 115]</a></span> +the stem and the rim with cotton wool. This precaution is to +prevent the larvæ from falling into the water as they attempt to +pass up or down the stem, and the wool also helps to keep the +twig in a vertical position. The glass is now ready for the caterpillars, +but it is advisable to keep a covering of muslin or gauze +over the top in all cases even though the larvæ contained are unable +to creep up the surface of glass, for the great enemies of caterpillars—the +ichneumon flies—are always on the alert, and will often take +advantage of an open window to 'sting' the larva rearer's pets.</p> + +<p>Another form of larva glass can easily be made out of a large +glass jar if you know how to cut off the bottom, or of a chemist's bell +jar which is open both at top and bottom. In this case the bottle +of water and the soil are arranged as +before in a pan of unglazed earthenware, +and then covered over with the +glass. This is shown in <a href="#FIG_58">fig. 58</a>, and is +an exceedingly convenient larva house, +since the lifting of the glass enables +you to get at the insects without any +trouble.</p> + +<div class="figleft" style="width: 300px;"> +<a name="FIG_59" id="FIG_59"></a><img src="images/i_132.jpg" width="300" height="300" alt="" title="" /> +<span class="caption">Fig. 59.—A Larva Cage.</span> +</div> + +<p>Wood larva cages are very commonly +used for the larger species after +they have attained a fair size and require +more food than can be stocked +in bottles and glasses. These cages +have glass fronts, either sliding or in +the form of a hinged door, and sides +of perforated zinc. They are kept in +stock by all dealers in entomologists' requisites, but equally useful +ones are easily constructed. If you select a box of suitable size at +the grocer's, cut out large pieces from the lid and sides with a fret +saw, and fix in the glass and zinc, you will have a cage that will +answer all purposes.</p> + +<p>The internal arrangements consist of a shallow tray filled with +soil, in which stands the bottle of water for the food, and a layer of +moss sufficiently high to cover the bottle completely.</p> + +<p>A series of such boxes standing on end on a shelf, or hanging on +a wall, will form a very satisfactory nursery for your pets, and will +occupy but little space.</p> + +<p>We have already observed that some larvæ burrow into soil +when about to change, while others creep to a sheltered corner, or<!-- Page 116 --><span class="pagenum"><a name="Page_116" id="Page_116">[Pg 116]</a></span> +suspend themselves from the food plant itself. It will be seen that the +larva cage just described supplies all these demands, and care must be +taken not to disturb the occupants while they are undergoing their +metamorphoses. Those that suspend themselves on the food plant +should be allowed to remain where they have fixed themselves, and +when it is necessary to remove the stale food in order to give a fresh +supply to the later larvæ, let it be fixed in an airy place where it can +be watched till the perfect insects emerge. Those which suspend +themselves on the sides or top of the cage, or spin cocoons in the +corners, should never be disturbed unless you are greatly in want of +the same cage for the accommodation of another brood; and even +then it is possible that their presence will not in any way interfere +with the new species. But if their removal becomes a necessity, let +it be carried out as carefully as possible, and not until the change +to the pupal stage is known to be complete.</p> + +<p>The species that burrow into the soil or bury themselves in the +moss need never be disturbed till the rearing season is quite over, +and then they may be transferred to a box specially kept for the +accommodation of pupæ.</p> + +<p>There is yet another method of rearing larvæ to which we must +refer—a method known as 'sleeving'—particularly useful when +you happen to have the required food plants in your own garden. +The ova or larvæ are placed on the plant, the whole or part of +which is then covered with a bag or 'sleeve' of gauze. The larvæ +thus imprisoned have the full benefit of fresh air and light, and +are also free from the attacks of ichneumon flies. They have a +fair amount of liberty, and yet cannot get beyond your reach; +also abundance of fresh food without further trouble on the part of +the rearer.</p> + +<p>But even this arrangement is not perfection. It will not suit +the night feeders that like to hide beneath the soil during the day, +and it interferes somewhat with the burrowing tendencies of those +which pupate underground. These little difficulties, however, can +be overcome by placing the food plants in large pots or tubs of +soil, and tying the mouth of the 'sleeve' round the outside of this +utensil. If this cannot be done, those insects that pupate underground +must be removed from the plant when their restless +disposition shows that the changing time has arrived, and then be +transferred to a box of soil where they can find the seclusion they +seek.</p> + +<p>The larvæ that hybernate throughout the winter are rather<!-- Page 117 --><span class="pagenum"><a name="Page_117" id="Page_117">[Pg 117]</a></span> +more troublesome, especially those which are inclined to take a +ramble on certain mild days in search of food when none is at +hand. Still there is no reason why even a beginner should not +attempt the rearing of these. They will require food in the +autumn until the cold weather sets in, and again early in spring +as soon as the new leaves appear; but this is not of much +consequence to those who reside in districts where the required +food plants abound.</p> + +<p>Wood feeders also require some special treatment and precautions, +and the successful rearing of some is a matter of no little +difficulty. A wooden cage is, of course, quite out of the question +with these, unless you wish to test the power of their jaws. They +must be kept in large pots or jars, covered over with wire gauze or +perforated zinc, and supplied with fresh stems or logs of wood, or +with moist sawdust fresh from their favourite tree. A few of them—the +'Goat' (<a href="#Page_224">page 224</a>), for example—will eat dead and rotting +wood, and may be fed on old palings and other waste providing the +right kind is selected.</p> + +<p>The troubles and disappointments of larva rearers are numerous +and varied, and commence with the earliest moments of the +young insects. Even the hatching period sometimes proves a +trial, for it occasionally happens that the young larva has not +sufficient strength to bite its way through the shell that surrounds +it, and dies with nothing but the surface of its head exposed to +view. This may be the result of keeping the ova in too dry a spot, +the shell having become too hard and horny for the little creature's +jaws.</p> + +<p>Then the moulting seasons are always periods of trial to the +larvæ, and often of loss to the rearer. Some of the hardier species +may pass through all their moults without appearing to suffer anything +more than a slight inconvenience at each, but in other cases +the greater part of a brood may fall victims to these ailments of +the growing stage.</p> + +<p>Apart from these sources of loss, however, larvæ are subject to +numerous diseases, infectious and otherwise, about which we know +but little. A fever may rage in one of our cages; a fungoid growth +may establish itself on the bodies of our pets, or we may see them +cut down, one by one, through a fatal attack of diarrhœa.</p> + +<p>In many such cases we are at a loss as to what to do. Blue +pills and black draughts are not to be prescribed, and the modern +practices of surgery and inoculation have not yet been applied to<!-- Page 118 --><span class="pagenum"><a name="Page_118" id="Page_118">[Pg 118]</a></span> +insect patients with very great success; but we must do our best +to adopt hygienic principles, paying the greatest attention to +proper means of ventilation and to a regular and wholesome dieting. +In the case of diarrhœa—a very common insect malady—the +best we can do is to avoid the young and juicy leaves of the food +plant, and substitute the older, and drier foliage.</p> + +<p>Ichneumon flies have already been mentioned as great enemies +of larvæ. These flies either deposit their eggs on the skins of +caterpillars, or thrust their sharp <i>ovipositors</i> into the creature's +flesh and lay their eggs beneath the skin. When the young +ichneumons are hatched, they immediately begin to feed on the +fatty matter that is usually stored in comparative abundance under +the skin of the caterpillar, and thus they grow at the expense of +their host, within whose body they lie completely hidden from +view.</p> + +<p>The poor caterpillar, though being eaten alive, often shows no +external signs of the mischief wrought within, and, even though +its substance is really decreased by the hungry internal parasites, +yet the rapid growth of these robbers maintains the general plumpness +of a healthy larva. But the ichneumons, having at last +devoured the store of fat, and avoided the vital organs of the +caterpillar, as if with a view to preserve their living home to the +latest moment, now commence to attack the latter, speedily +reducing the vitality of their host to the lowest ebb, and finally +causing its death.</p> + +<p>This untimely end may come before the caterpillar is full grown, +or the insect may change to the pupa before the ichneumons have +done their worst, but it rarely occurs that the unfortunate creature +has sufficient strength to carry it on to the final stage.</p> + +<p>A large number of the collected larvæ will have been 'stung,' +much to the disgust and disappointment of the rearer; and hence +the advantage of rearing your specimens from ova wherever possible, +providing you keep them so well under cover that the ichneumons +cannot visit your broods.</p> + + +<h4><i>The Management of Pupæ</i></h4> + +<p>The disappointments connected with the rearing of <i>Lepidoptera</i> +are by no means at an end when all have passed successfully into +the pupal condition, and the number of perfect insects obtained +will often fall far short of the number of pupæ in your boxes; but<!-- Page 119 --><span class="pagenum"><a name="Page_119" id="Page_119">[Pg 119]</a></span> +we must now see what can be done to minimise the death rate of +the captives.</p> + +<p>One or more suitable boxes must be prepared for the reception +of the pupæ, and the following suggestion will answer all +purposes:</p> + +<p>Get a wooden box, quite rough and unplaned inside, large enough +to accommodate your pupæ with ease, and not less than eight +inches deep. Make several holes in the bottom, or else knock the +bottom completely out, and nail in its place a sheet of perforated +zinc. Also make a lid consisting of gauze attached to a light wood +frame.</p> + +<p>Place a layer of clean gravel, about an inch deep, in the bottom, +and over this a few inches of sifted soil or cocoa-nut fibre.</p> + +<p>Now take all the pupæ that are 'earthed' in your cages, and +arrange them on the prepared bed; also add to them the pupæ +you may have dug out during your various excursions. Cover all +with a layer of the material selected for the bed, and then add a +layer of moss.</p> + +<p>Next come the pupæ that are suspended by silky fibres, or are +inclosed in cocoons. These should be fixed with pins around +the sides of the box, running the pins either through the tuft of +silk at the 'tail,' or the outer layer of the cocoon, or through the +portion of the dried food plant to which they are attached.</p> + +<p>Here your pupæ will remain till they emerge, and the box may +be kept in any airy place where it is not likely to be forgotten, for +it is essential that the perfect insects should be removed as soon +as possible after quitting their cases. It does not matter much +whether the pupæ be kept in or out of doors, providing they are +sheltered from rain and very severe frosts; but of course, if the +former, the imagines will emerge a little earlier, even if the room +in which your specimens are stored has no fire.</p> + +<p>Even when protected in boxes such as that described the pupæ +are subject to enemies and dangers. The soil and moss employed +may contain slugs, mites, or other creatures which prey on insects, +and the amount of moisture present in these materials and in the +atmosphere may prove too little for some species or too much for +others.</p> + +<p>The remedy for the former evil is a simple one. Bake the soil +or fibre well before fitting up the box, and boil and afterwards dry +the moss. You may then be sure that all life previously contained +is quite destroyed.<!-- Page 120 --><span class="pagenum"><a name="Page_120" id="Page_120">[Pg 120]</a></span></p> + +<p>But the degree of humidity is a point not so easily settled, and +so variable are the experiences and opinions of different entomologists +that it is difficult to advise a beginner on the subject. The +fact that some strongly advise a perennial dampness, while others +recommend no attempt at the application of water, would seem +to show that there are probably important points to be urged on +both sides.</p> + +<p>Nothing can be better than a very careful observation of pupæ +in their natural conditions. When engaged in pupa digging you +will observe that the larger number are to be found on the east and +north sides of trees where the soil is protected from the heaviest +rains; on the other hand a good many are certainly found in very +moist and sometimes even in wet situations.</p> + +<p>Particular notice should be taken of such experiences, making +every allowance for the exceptions that prove the rule, and then let +the natural conditions be maintained in your nurseries at home. +To carry this out two pupa boxes should be kept, one for those +species that seem to require dry situations, and the other for the +species that apparently do best with moist surroundings.</p> + +<p>But when it is desired to maintain the pupæ in a moist condition, +great care must be taken not to allow any accumulation of +stagnant water. The box we have described, with its bottom of +perforated zinc, is well adapted for this purpose. Let it stand on +a couple of strips of wood, so that any excess of moisture may +readily drain through. The perforated bottom will also allow of a +free circulation of air, thus securing the ventilation that is desirable +in all boxes, whether wet or dry.</p> + +<p>If you have any insects that have pupated within moist stems, +they should be kept in a moist condition till they emerge. The +simplest way of doing this is to support the stems in a layer of +wetted but well-drained silver sand.</p> + +<p>Forcing may be resorted to when it is required to obtain the +imagines for early setting in order to get them in the cabinet before +the busy season begins. The method is simple. Place the pupa +box on a shelf in a room where a fire is kept every day. By this +means you may get all your specimens out within a few weeks, +even when you start the forcing at the beginning or middle of the +winter. If, however, you require the imagines for breeding, you +must be careful that the eggs are not laid long before the buds of +the necessary food plants are due.</p> + +<p>When you are expecting the appearance of perfect insects, the<!-- Page 121 --><span class="pagenum"><a name="Page_121" id="Page_121">[Pg 121]</a></span> +pupa boxes should be examined every day.

Our first attention +shall be given to the apparatus necessary for this work.</p> + +<p>The most important requirement is the setting boards, of which +several are necessary, the sizes varying according to the dimensions +of the different insects to be 'set.' The <i>lengths</i> of all the boards +should be the same, not only for the convenience of packing when +not in use, but also in order that they may, if required, be arranged +neatly in the 'drying house' to be presently described. The widths +only will vary, and in this respect the boards must be adapted +to the measurements of the insects from tip to tip when the +wings are fully expanded. Thus, a set of a dozen boards, ten +or twelve inches long, and from one to five inches wide, will do +for a good start. Of course you may commence with a smaller +number than twelve, but if you really mean to do the thing well, +you will eventually require a good stock of boards.</p> + +<p>Here, again, it may be mentioned that all the necessary requisites +may be purchased ready for use, a set of boards and a drying +house complete costing from ten to twenty shillings according to +size and quality; but as the reader, like myself, may prefer to construct +his own, I will supply him with hints and suggestions sufficient +for the work.</p> + +<p>Each board is constructed in this way. Cut out and plane up +a piece of wood of the required length and breadth, and about one-eighth +of an inch thick. Glue on the top of this a layer of cork<!-- Page 123 --><span class="pagenum"><a name="Page_123" id="Page_123">[Pg 123]</a></span> +about half an inch in thickness, leaving the whole under a moderate +pressure until the glue is quite hard. The sheets of cork for this +purpose may be bought at any naturalist's stores; but slices cut +from good large bottle corks may be made to answer equally well +if you don't mind the extra time expended in cutting and fixing.</p> + +<p>When the glue has well set, trim off the edges of the cork flush +with the sides of the wood, +and then cut out a groove +down the whole length of +the cork, of course in the +middle, and of such a size +that it will just contain +the bodies of the insects for which it is intended.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_60" id="FIG_60"></a> +<img src="images/i_140a.jpg" width="300" height="60" alt="" title="" /> +<span class="caption">Fig. 60.—Section of a Setting Board.</span> +</div> + +<p>The satisfactory cutting of this groove is not a very easy matter, +but if its position is first carefully marked, a long rat-tail file may +be made to plough it out neatly and regularly. As an alternative +the following plan is good. First cover the wood with a layer of +cork about a <i>quarter</i> of an inch thick, and then glue on the top of +this <i>two</i> narrower strips, about as thick as the bodies of the insects +for which the board is intended, +leaving a space of the required +size between them, as shown in +<a href="#FIG_60">fig. 60</a>. In this way you get a +groove of square section, that is +in some respects preferable to +the round one cut out by means +of the rat-tail file.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_61" id="FIG_61"></a><img src="images/i_140b.jpg" width="300" height="294" alt="" title="" /> +<span class="caption">Fig. 61.—Sections of Setting +Boards.</span> +</div> + +<p>Now comes a question about +which there is a difference in the +tastes or fancies of entomologists. +Shall the boards be perfectly +flat on the top, or shall the sides +slope from the groove, or shall +the surface be rounded? A +glance at the three sections of +setting boards will show clearly what is meant. The rounded board +is most commonly used, and the graceful curve thus given to a +butterfly or moth set on such is certainly attractive; but it is not +natural. The wings of these insects are rigid, and are never seen +bent into such curves in a living specimen. For this reason I +much prefer a perfectly plane surface on each side of the groove.<!-- Page 124 --><span class="pagenum"><a name="Page_124" id="Page_124">[Pg 124]</a></span> +Then, as to whether there shall be a slope or not, this is a matter +of less importance. A very decided sloping of the wings is certainly +not so convenient for future examination; nor does it, to my mind, +look nearly so well as both sides in the same plane, or at a very +gentle inclination. But perhaps this subject had better be left to +the taste of the reader, remembering, however, that, whatever plan +be adopted, all the boards should be alike in this respect, so that +there may be a degree of uniformity in the cabinet.</p> + +<p>The surface of the cork must, in all cases, be nicely smoothed +down with glass paper, and then covered with thin white paper, +fixed to its surface with ordinary paste.</p> + +<p>When insects are on the boards, they should be placed in an +airy spot, as free as possible from dust, while they are drying. +Hence the advisability of some form of 'drying house.' This is +simply a box, standing on end, +and provided with a hinged door +consisting of a sheet of perforated +zinc in a wooden frame. +The boards may slide in this on +little slips of wood nailed or +glued on to the sides, or the +wooden bases of the boards may +project beyond the cork at the +ends, and slide into grooves in +the side of the house.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_62" id="FIG_62"></a><img src="images/i_141.jpg" width="300" height="263" alt="" title="" /> +<span class="caption">Fig. 62.—A Butterfly on the +Setting Board.</span> +</div> + +<p>Beyond these requirements +nothing is wanted save a good +stock of pins, thin card or ordinary +writing paper, and a 'setting needle.' The last-named item +is simply a needle mounted in a handle, and a good one may be +made by thrusting the head of a darning needle into a piece of twig. +The pins used for setting—that is, for fixing the pieces of paper or +card to keep the parts in position—may be of the ordinary kind; +but entomological pins are far preferable, even for this purpose; +for, being much thinner, they do not damage and disfigure the +setting boards so much.</p> + +<p>Now as to the setting. First see that the pin with which you +are to fix your dead insect passes centrally through the thorax. +Then fix it firmly on the setting board, its body lying neatly in the +groove of the cork. Cut out some little pointed strips of card or +paper, and, after bringing the wings into position with the setting<!-- Page 125 --><span class="pagenum"><a name="Page_125" id="Page_125">[Pg 125]</a></span> +needle, fix each one by a pinned strip. In spreading out the wings, +care must be taken not to pierce them at all, but simply to push +them into their place by pressing the needle at their bases, or by +putting the needle beneath and <i>lifting</i> them out.</p> + +<p>Instead of pointed pieces of card, uniform strips of paper may +be used, as shown in <a href="#FIG_63">fig. 63</a>, each strip passing over both wings.</p> + +<p>After the four wings have been properly arranged, a few extra +pins may be used to keep other parts in position. Thus, the +antennæ may be placed at equal angles, the proboscis may be extended, +and a couple of pins may be used to support the abdomen +if it is inclined to bend downward.</p> + +<div class="figcenter" style="width: 400px;"> +<a name="FIG_63" id="FIG_63"></a> +<img src="images/i_142.jpg" width="400" height="400" alt="" title="" /> +<span class="caption">Fig. 63.—Another Method of Setting +Butterflies and Moths.</span> +</div> + +<p>As before mentioned, +insects should +be set soon after they +are dead, while the +parts are still soft and +supple. But where +this cannot be done, +and the specimens have +become stiff, brittle, +and rigid, they must be +'relaxed' before any +attempt is made at +setting them out.</p> + +<p>This process of relaxing +consists in placing +the specimens in a +very moist atmosphere +for a few days. There +are several simple +ways of doing this, many of which will readily suggest themselves +to the reader. Your collecting box, if a zinc one, may also be +used as a relaxer. Pin your stiff insects in it, after well moistening +the cork, and simply shut them up for a day or two. Any metal box +will serve the same purpose providing you put into it a piece of +sheet cork on which to fix the insects, and this cork may rest on a +bed of moist sand.</p> + +<p>Another plan is to float the pinned specimens on corks in a +shallow vessel of water, and cover them over with a bell glass.</p> + +<p>Insects that are being relaxed should be examined from time +to time, and the degree of flexibility acquired tested by a gentle<!-- Page 126 --><span class="pagenum"><a name="Page_126" id="Page_126">[Pg 126]</a></span> +pressure of the setting needle or by blowing on them. If not +sufficiently supple, give another day in the damp cell, but never +allow them to be forgotten till they are covered with mildew.</p> + +<p>The time occupied in thoroughly drying butterflies and moths +will vary considerably according to their sizes and the condition of +the atmosphere. In hot and dry summer weather four or five days +will prove quite sufficient for the <i>very</i> small and thin-bodied species. +From one to two weeks, however, may be looked upon as the +average period; but the large and thick-bodied moths may require +more than this.</p> + +<p>Perhaps the best test of their condition is the gentle pressing of +the setting needle against the abdomen—the last part of the body +to become dry and stiff. If the abdomen seems quite firm and +rigid, you are pretty safe in removing the specimen from the +board; but if it bends at all under a slight pressure of the needle +let it remain for a day or two longer.</p> + +<p>If your cabinet is quite ready for the reception of new-comers, +the insects may be put in their proper places immediately after +their removal from the setting boards; but if not, they may +be pinned temporarily in a 'store box' till the time comes when +you have proper accommodation provided. The full consideration +of these matters will be dealt with in another chapter.</p> + +<p>It is possible that the setting of some of your specimens will not +exactly please you. If such is the case, put them in a relaxing box +for a day or two, and then reset them more to your fancy.</p> + +<p>We have now to deal with a matter that applies more +particularly to moths, especially the very large and thick-bodied +species. The abdomens of these become more or less contracted +and shrivelled on drying, sometimes to such an extent as to look +most unsightly.</p> + +<p>There is a remedy for this, and the time and patience required +in working it out will be well repaid by the superior results +obtained.</p> + +<p>While the abdomen is still in a soft condition, make a slit +throughout its length with a very sharp knife or a sharp-pointed +pair of scissors. This slit should be made down the centre of the +under surface, or, if the insect is to be placed in the cabinet with +the under side exposed, down the middle line of the back. Then +remove all the contents of the abdomen, scraping them out with a +piece of hooked wire, or removing them with a fine pair of forceps, +and leaving the skin as clean as possible both within and without.<!-- Page 127 --><span class="pagenum"><a name="Page_127" id="Page_127">[Pg 127]</a></span> +Now introduce a packing of cotton wool, just sufficient in quantity +to maintain the natural form of the body as the specimen +dries.</p> + +<p>There is another good method of stuffing moths that possesses +a decided advantage over the one just described, since it leaves the +specimen in such a perfect condition that it shows no appearance +of having been stuffed when viewed from either side. This consists +in snipping off the abdomen at the waist, clearing out the contents +with a hooked wire, lightly stuffing it with cotton wool pushed in +at the waist, and then setting it aside to dry, while the other part +of the insect is undergoing the same process on the setting board. +When both parts of the moth are thoroughly dry, the stuffed +abdomen is easily fixed in its place with a little coaguline; and this, +if neatly done, will not show the slightest sign of the treatment to +which the insect has been submitted.</p> + +<p>Even after your insects are finally housed in the cabinet, they +are subject to two other dangers, both of which are more destructive +to moths than to butterflies. One is technically known +as 'grease,' and the other is the invasion of certain museum pests +that feed on the specimens, causing them to fall to pieces.</p> + +<p>Examine the moths that have been for a time in the cabinet, +and some are sure to exhibit an oily or greasy appearance, the hairs +of the abdomen, and perhaps also of the thorax, being clogged +together just as if the specimen had been dipped in oil, the +same miserable condition perhaps being shared also by parts of +the wings.</p> + +<p>This is due to the gradual oozing out of the fatty matter that +is always present to a greater or less extent in the bodies of the +insects, and which must necessarily show itself more sparingly in +specimens that have been carefully stuffed.</p> + +<p>The old saying, 'Prevention is better than cure,' applies well in +the present case; but as there are times when a knowledge of the +'cure' is the only means of saving a valuable specimen from +destruction, we will study both.</p> + +<p>To deal with the two in the order of the well-worn proverb, we +will consider the prevention first. Always carefully clean out and +stuff the abdomens of large-bodied insects; and as a rule, treat them +with some substance that will either absorb or dissolve out all oily +matter. I think the best plan is to remove the abdomen, clean it +out if its size permits of such an operation, and then, after labelling +it to prevent its future application to the wrong body, either let it<!-- Page 128 --><span class="pagenum"><a name="Page_128" id="Page_128">[Pg 128]</a></span> +remain in a bottle of magnesia for several weeks, or soak it in benzole +or ether for a few hours or longer.</p> + +<p>If magnesia has been employed as an absorbent, you have +simply to blow or lightly brush off the loose powder that clings to the +body, and then fix it in its place with coaguline. A body dipped in +ether or benzole will look as if completely spoilt at first, for the furry +coat that clothes it will lie matted and almost entirely robbed of its +beautiful colours, reminding one forcibly of the proverbial 'drowned +rat.' But take no notice of this change. Let the body have at +least a few hours in the liquid, extending the time to a day or two +in the case of very large ones and those which experience has +proved to be particularly liable to 'grease;' and, immediately on +withdrawing it, fix it with a pin in a good strong draught, such as +you may obtain by opening a window about an inch, or, if a breezy +day, in the open air.</p> + +<p>These liquids are so volatile (and for that reason should never +be left exposed in an open vessel) that they rapidly evaporate, +leaving the dry hair to be loosened by the breeze, thus bringing +back the natural appearance almost perfectly.</p> + +<p>It is probable that many of the smaller insects that were not +considered to require the stuffing or grease-removing operations +will sooner or later exhibit a greasy tendency in the cabinet. At +first the abdomen is affected, and the oily matter then gradually +creeps over the rest of the body, finally spreading over the wings, +and giving the insect a most deplorable aspect. But these are not +irreparably lost, and the following cure will often bring them back +to their former beauty.</p> + +<p>If the abdomen only shows signs of grease, cut it off and soak +it in one of the above-named liquids for a day or so, replacing it as +above after the drying operation. If, however, the oily matter +has spread to the thorax and the bases of the wings, the whole +specimen must be soaked, using a basin or jar of suitable size, +covered with a plate of glass. A good draught during the drying +operation will do much to prevent the hair from sticking in matted +tufts close against the surface of the body and wings, and a gentle +brushing with a very soft camel-hair brush will loosen and reset +the fur.</p> + +<p>The other danger to which we have referred is the invasion of +certain 'mites' and other museum pests that pay periodical visits +to our cabinet drawers and store boxes, often committing such +havoc as to severely try the patience of an interested naturalist.<!-- Page 129 --><span class="pagenum"><a name="Page_129" id="Page_129">[Pg 129]</a></span></p> + +<p>The way to prevent such intrusions is to make the atmosphere +of the compartments so obnoxious (to them) that they dare not +enter; and, further, to so spice up your specimens that they are +no longer safely edible to the invaders.</p> + +<p>The first object can be attained by always keeping camphor or +naphthaline (albo-carbon) in each division. A lump of either substance +may be secured by pins or a little perforated cell in the +corner of each drawer or box, or the bottom of each may be dusted +with finely powdered naphthaline; but as both these solids are +volatile, care must be taken to renew the supply as occasion +requires.</p> + +<p>Then, with regard to the second precaution, perhaps nothing +is more effectual than corrosive sublimate. A little of this may be +dissolved in a small bottle of alcohol (spirits of wine), labelled with +the name and the word <span class="smcap">Poison</span>, and kept ready for use. All the +skins of stuffed specimens should be painted with this solution, and +the stuffing itself may be moistened with it before insertion.</p> + +<p>There is yet another circumstance that renders a watchful care +of your cabinet specimens necessary, if you happen to possess +many that were captured 'at sugar.' Some of these will have so +gorged themselves with syrup that they are literally full of it, and +this will sometimes find its way to the outside, often dropping on +the surface beneath. In such cases the sugar should be removed +as completely as possible, and the bodies stuffed, before they are +quite dry; but if the specimens have been in the cabinet so long +that they are stiff and hard, the under sides of the abdomens may +be completely cut out with a very sharp knife and thrown away, +and then the sugar cleaned out from the upper shell as neatly as +possible.</p> + + + +<hr /> +<p><!-- Page 130 --><span class="pagenum"><a name="Page_130" id="Page_130">[Pg 130]</a></span></p> +<h3>CHAPTER X +<br /> +<i>PRESERVING OVA, LARVÆ AND PUPÆ</i></h3> + + +<p>Many young entomologists give their attention almost solely to the +perfect forms of insects, often collecting and studying a very large +number of species without regard to their earlier stages and metamorphoses. +This is decidedly a very great mistake. Although +the lifeless form pinned in a cabinet may be a most beautiful object +in itself, yet a study of this alone is uninteresting compared with +that of the wonderful changes it has undergone since the time it +was a very young larva.</p> + +<p>The different stages of the insects should be known as far as +possible, and these, as well as the perfect forms, should be included +in the collection for future study and reference. A good cabinet, +according to my own opinion, is one that possesses, among other +good features, a number of complete sets illustrative of the life +history of at least the more typical forms; and as it is not a +difficult matter to preserve the earlier stages, there is really no +excuse for their omission from the collection.</p> + +<p>The empty shells of ova are in themselves sometimes interesting +objects, especially when they illustrate some peculiar instinct +on the part of the parent. Sterile eggs, also, often fall into the +hands of breeders and rearers, and these, though in other respects +unprofitable, are useful in the cabinet.</p> + +<p>If fertile eggs are to be prepared for a collection, they must be +killed. This is easily done by thrusting into each one the point of +a very fine needle, or by immersing them for a moment in boiling +water, or by shutting them up in a bottle with camphor. In drying +they often contract more or less, and frequently change their +colour; still these are useful, providing notes have been taken of +the characters thus lost. The larger eggs are capable of special +treatment where the owner has the necessary time and patience, +and where the highest results are desired. By means of a surgeon's<!-- Page 131 --><span class="pagenum"><a name="Page_131" id="Page_131">[Pg 131]</a></span> +injector of small size the contents of the eggs can be removed; and +then, by the same instrument, a warm solution of gelatine, coloured +in such a way as to restore the natural tint, may be forced into the +empty shell. As the gelatine cools and hardens, it prevents any +shrinking of the shell, and thus both form and colour are well +preserved.</p> + +<p>For the preservation of larvæ you will require one or two +simple appliances.</p> + +<p>The first of these is a suitable glass blowpipe, one form of which +is here illustrated. It consists of a glass tube, one end of which +has been drawn out very fine; a piece of watch spring tied to it in +such a manner that it will hold the skin of a larva at the small end, +and a piece of india-rubber tubing at the other end, pressed by +means of a brass spring clip.</p> + +<div class="figcenter" style="width: 400px;"> +<a name="FIG_64" id="FIG_64"></a><a href="images/i_148.jpg"><img src="images/i_148_tn.jpg" width="400" height="80" alt="" title="[Larger image of Figure 64.]" /></a> +<span class="caption">Fig. 64.—A Blowpipe for Larvæ.</span> +</div> + +<p>A little drying oven is also very useful, but not absolutely necessary. +If you decide to have one, any square box of sheet iron (not +soldered tinned iron) may be readily converted into one. It must +be provided with a hinged door in the front with a ventilator at the +bottom, a hole for the escape of hot air at the top, and a tripod wire +stand inside on which to rest the specimens while drying. The +whole should be supported on a wire stand, so that heat may be +applied below.</p> + +<p>Each larva to be preserved should be dealt with in this way. +First kill it by means of any one of the killing bottles or boxes already +described, or by immersion in spirit of wine. When quite dead, +enlarge the anal orifice by thrusting a needle into it, and then lay +it on a piece of blotting paper with its head toward you. Now +take a round ruler, previously covered with blotting paper, and roll +the larva gently from head to tail till all the contents of the skin +have been expelled. Next fix the skin on the fine end of the blowpipe, +by thrusting the point of the latter into the opening, and +allowing the spring to press gently on its edge. Gently blow into +the skin till it is inflated just to a <i>little below</i> natural size, then<!-- Page 132 --><span class="pagenum"><a name="Page_132" id="Page_132">[Pg 132]</a></span> +either hold it near a fire or rest it in the drying oven till it is quite +dry and rigid.</p> + +<p>If you have done your work neatly, the skin and blowpipe will +both be quite air-tight when the clip is closed; and the air, finding +no outlet, will still further inflate the skin when it expands on +exposure to heat. This is the reason why you are directed to blow +it out to something short of the natural dimensions. If you find +that this expansion causes the skin to stretch beyond its normal +size, a little of the air must be allowed to escape while it is yet soft +and flexible.</p> + +<p>The front of the larva is generally the last portion to become +dry, and when this is quite rigid the skin may be removed from +the blowpipe. This is a matter that requires the greatest care; for +the skin is so very thin and brittle that a little rough handling will +break it to pieces. As a rule it may be easily pushed off the pipe +by a slight pressure behind, or a gentle twisting motion will loosen +its hold; but this latter method can hardly be applied to hairy +larvæ without breaking off the hairs, now rendered very brittle by +the heat.</p> + +<p>If you find the slightest difficulty in detaching the skin of a +valuable specimen, it is far better to damage the blowpipe than to +risk spoiling the skin. Supposing your blowpipe is a glass one, +you can easily break off the end of it after making a cut with a very +small triangular file, and the portion thus removed may be left +attached to the skin. Then, after softening the glass blowpipe in a +gas flame or the flame of a spirit lamp, it can be drawn out thin +again for future work. Those who can manipulate glass tubing in +this way will find it far better to lay in a stock of suitable material, +drawing it out when required, than to purchase blowpipes ready +made at the naturalist's shop.</p> + +<p>Very fine hollow stems, such as those of the bamboo cane, may +be used instead of glass; and these possess the advantage of being +easily cut with a sharp knife when there is any difficulty in removing +the skin. Again, whether glass or fine stems are used, a little +grease of any kind placed previously on the end will allow the dried +skin to be slid off with less difficulty.</p> + +<p>Preserved larvæ should preferably be mounted on small twigs +or artificial imitations of the leaves of the proper food plants. A +little coaguline applied to the claspers will fix them very firmly on +these twigs or leaves, which are then secured in the cabinet by +means of one or two small pins.<!-- Page 133 --><span class="pagenum"><a name="Page_133" id="Page_133">[Pg 133]</a></span></p> + +<p>It is much to be regretted that the natural colours of many +caterpillars cannot be preserved in the blown skins. Some are +rendered much lighter in colour on account of the withdrawal of +the contents, while others turn dark during the drying. In the +smooth-skinned species the natural tints may be restored by painting +or by staining with suitable aniline dyes, but these artificial imitations +of the natural colours are always far less beautiful than the +hues of the living larvæ.</p> + +<p>Very few words need be said on the preservation of pupæ. +Many of them do not alter much in form and colour, and therefore +they require no special preparation.</p> + +<p>If a pupa has to be killed for the purpose of adding to the value +of the collection, simply plunge it into boiling water, and it is ready +to be fixed in the cabinet as soon as it is quite dry.</p> + +<p>The empty pupa cases, too, from which the perfect insects have +emerged, are often worth preserving, especially if the damage done +by the imago on forcing its way out is repaired with the aid of a little +coaguline.</p> + +<p>Let all larvæ and pupæ be preserved in their characteristic attitudes +and positions as far as possible, so that each one tells some +interesting feature of the life history of the living being it represents. +Further, enrich your collection by numerous specimens of +the various kinds of cocoons constructed by the larvæ, pinning each +one beside its proper species; and never refuse a place to any +object that relates something of the life history of the creatures +you are studying.</p> + + + +<hr /> +<p><!-- Page 134 --><span class="pagenum"><a name="Page_134" id="Page_134">[Pg 134]</a></span></p> +<h3>CHAPTER XI +<br /> +<i>THE CABINET</i>—<i>ARRANGEMENT OF SPECIMENS</i></h3> + + +<p>The selection of a cabinet or other storehouse for the rapidly +increasing specimens of insect forms is often a matter of no small +difficulty to a youthful entomologist. Indeed, there are very many +points of considerable importance to be considered before any final +decision is made. Freedom from dust, the exclusion of pests, the +convenience of the collector, the depth of his pocket, and the +general appearance of the storehouse must be considered, and it is +impossible, therefore, to describe a form that is equally suitable +to all.</p> + +<p>If it is absolutely necessary that the cabinet (or its substitute) +be of a very inexpensive character, and if, at the same time, the +collector has not the mechanical skill necessary for its construction, +then perhaps the best thing he can do is to procure a number of +shallow (about an inch and a half deep) cardboard, glass-topped +boxes, such as are to be obtained at drapers' shops. For the sake +of uniformity and convenience in packing, have them all of one +size. Glue in small slices of cork just where the insects are to be +pinned, and see that each box is supplied with either camphor or +naphthaline. All the boxes may be packed in a cupboard or in a +case made specially to contain them; and a label on the front of +each will enable you to select any one when required without disturbing +the others.</p> + +<p>It may be mentioned here that glass is not necessary, though it +is certainly convenient at times, especially when you are exhibiting +your specimens to admiring non-entomological friends, who have +almost always a most alarming way of bringing the tip of the first +finger dangerously near as they are pointing out their favourite +colours. 'Isn't <i>that</i> one a beauty?' is a common remark, and<!-- Page 135 --><span class="pagenum"><a name="Page_135" id="Page_135">[Pg 135]</a></span> +therewith off snaps a wing of one of your choicest insects. When +glass is used, however, see that the specimens are excluded from +light, or the colours will soon lose their natural brilliancy.</p> + +<p>Anyone who has a set of carpenter's tools and the ability to use +them well will be able to construct for himself either a set of store +boxes or a cabinet of many drawers in which to keep his natural +treasures. In this case a few considerations are necessary before +deciding on the form which the storehouse is to take.</p> + +<p>A cabinet, if nicely made, forms a very sightly article of furniture; +and, if space can be found for it, is the best and most convenient +receptacle. One of about twelve to twenty drawers will be +quite sufficient for a time; and the few following hints and suggestions +may be useful.</p> + +<p>The wood used should be well seasoned, and free from resin. +The drawers should fit well, and slide without the least danger of +shaking. Each one should be lined with sheet cork, about one-eighth +of an inch thick, glued to the bottom, nicely levelled with +sand paper, and then covered with thin, pure white paper, laid on +with thin paste. It is also advisable to cover each with glass, +inclosed in a light wood frame that fits so closely as to prevent the +intrusion of mites.</p> + +<p>The drawers may be arranged in a single vertical tier if the +cabinet is to stand on the floor, or in two tiers if it is to be shorter +for placing on the top of another piece of furniture; and glass doors, +fastened by a lock and key, may be made to cover the front if such +are desired as a matter of fancy, or as a precaution against the +meddlesome habits of juvenile fingers.</p> + +<p>Store boxes are sometimes chosen in preference to cabinets +because they are more portable, and because they can be arranged +on shelves—an important consideration when floor space is not +available.</p> + +<p>These boxes should be cork-lined and glazed like the cabinet +drawers; and if they are made in two equal portions, lined with +cork on both sides, and closing up like a book, they may be arranged +on shelves like books, in which position they will collect but little +dust.</p> + +<p>Both store boxes and cabinets are always kept in stock by the +dealers, the former ranging from a few shillings each, and the latter +from fifteen shillings to a guinea per drawer. Knowing this, you +can decide for yourself between the two alternatives—making and +purchasing.<!-- Page 136 --><span class="pagenum"><a name="Page_136" id="Page_136">[Pg 136]</a></span></p> + +<p>We have now to consider the manner in which our specimens +should be arranged and labelled.</p> + +<p>The table forming <a href="#APPENDIX_I">Appendix I</a> contains the names of <i>all</i> the +British butterflies and larger moths, and shows their division +into <i>Sections</i>, <i>Tribes</i>, <i>Families</i>, and <i>Genera</i>.

I shall now give such a brief description of individual +species as will enable the reader to recognise them readily. We +will begin with the butterflies.</p> + + + +<hr /> +<h3><a name="CHAPTER_XII" id="CHAPTER_XII"></a>CHAPTER XII +<br /> +<i>THE SWALLOW-TAIL AND THE 'WHITES'</i></h3> + + +<h4>Family—<span class="smcap">Papilionidæ</span> +<br /><br /> +<i>The Swallow-tail</i> (<i>Papilio Machaon</i>)</h4> + +<p>Our first family (<i>Papilionidæ</i>) contains only one British species—the +beautiful Swallow-tail (<i>Papilio Machaon</i>), distinguished at once +from all other British butterflies by its superior size and the 'tails' +projecting from the hind margin of the hind wings.</p> + +<p>This beautiful insect is figured on <a href="#Frontispiece">Plate I</a>, where its bold black +markings on a yellow ground are so conspicuous as to render a +written description superfluous. Attention may be called, however, +to the yellow scales that dot the dark bands and blotches, making +them look as if they had been powdered; also to the blue clouds +that relieve the black bands of the hind wings, and the round reddish +orange spot at the anal angle of each of the same wings.</p> + +<p>It appears that this butterfly was once widely distributed +throughout England, having been recorded as common in various +counties, and has also been taken in Scotland and Ireland; but it +is now almost exclusively confined to the fens of Cambridgeshire,<!-- Page 140 --><span class="pagenum"><a name="Page_140" id="Page_140">[Pg 140]</a></span> +Huntingdonshire, and Norfolk. Occasionally we hear of the capture +of single specimens quite outside these localities, sometimes even +in most unlikely spots, where its food plant does not abound. But +we know that <i>Machaon</i> is a general favourite with entomologists, +and that it is sent in the pupal state, by post, to all parts of the +kingdom; so that the occasional capture of the insect far beyond +the borders of its haunts is probably the outcome of an escape from +prison, or of the tender-heartedness of some lover of nature who +could not bear to see such a beautiful creature deprived of its short +but joyous, sunny flight.</p> + +<p>You cannot hope to see this splendid butterfly on the wing unless +you visit its haunts during its season—May to August; but the +pupæ may be purchased for a few pence each from most of the +entomological dealers; and if you obtain a few of these and watch +them closely, you may be fortunate enough to see the perfect insect +emerge from its case, and witness the gradual expansion of its +beautiful wings.</p> + +<p>The pupa (<a href="#Plate_VIII">Plate VIII</a>, fig. 7) itself is a most beautiful object. +Its colour is a pale green, and it is fixed to its support by the tail, +and further secured by a very strong silk band.</p> + +<p>The larva (<a href="#Plate_VIII">Plate VIII</a>, fig. 1), too, is exceedingly beautiful. Its +ground colour is a lovely green, and twelve velvety black rings +mark the divisions between the segments. Between these are also +black bars, all spotted with bright orange except the one on the +second segment.</p> + +<p>A remarkable feature of this larva is the possession of a forked, +<span class="lettershape">Y</span>-shaped 'horn,' that is projected from the back, just behind the +head, when the creature is alarmed. If it is gently pressed or +irritated in any way, this horn is thrust out just as if it were an +important weapon of defence. And perhaps it is, for it is the source +of a powerful odour of fennel—one of the food plants of the caterpillar—that +may possibly prove objectionable to some of its numerous +enemies.</p> + +<p>The food plants of <i>Machaon</i> are the milk parsley or hog's +fennel (<i>Peucedanum palustre</i>), cow-parsnip (<i>Heracleum sphondylium</i>), +and the wild angelica (<i>Angelica sylvestris</i>); but in confinement +it will also partake of rue and carrot leaves.</p> + +<p>The caterpillar of this species may be found in the fens during +the greater part of the summer. It turns to a chrysalis in the +autumn, and remains in this state throughout the winter, attached +to the stems of reeds in the vicinity of its food plants. The perfect<!-- Page 141 --><span class="pagenum"><a name="Page_141" id="Page_141">[Pg 141]</a></span> +insect is first seen in May, and is more or less abundant from this +time to the month of August.</p> + + +<h4>Family—<span class="smcap">Pieridæ</span></h4> + +<p>This family, though known commonly as the 'Whites,' contains +four British species that display beautiful tints of bright yellow or +orange.</p> + +<p>In many respects the <i>Pieridæ</i> resemble the last species. Thus +the perfect insects have six fully developed legs; the caterpillars +are devoid of bristles or spines; and the chrysalides are attached +by means of silky webs at the 'tails,' and strong cords of the same +material round the middle.</p> + +<p>All the larvæ are also cylindrical or wormlike in shape; and +their skins are either quite smooth, or are covered with very short +and fine hairs, that sometimes impart a soft, velvety appearance.</p> + +<p>The members of this family are remarkable for their partiality +for certain of our cultivated plants and trees; and are, in some +cases, so abundant and so voracious, that they are exceedingly +destructive to certain crops.</p> + + +<h4><i>The Black-veined White</i> (<i>Aporia Cratægi</i>)</h4> + +<p>This butterfly may now be regarded as one of our rarities. At +one time it was rather abundant in certain localities in England, +among which may be mentioned the neighbourhoods of Cardiff and +Stroud, also parts of Kent, Sussex, Hampshire, Huntingdonshire, and +the Isle of Thanet; but it is to be feared that this species is nearly +or quite extinct in this country. It is well, however, not to give up +the search for it, and if you happen to be in one of its favoured +localities of former days, you might net all the doubtful 'Whites' +of large size that arouse your suspicions, liberating them again if, +on inspection, they do not answer to the description of the species +'wanted.' This course becomes absolutely necessary, since the +Black-veined White is hardly to be distinguished from the Common +Large White while on the wing.</p> + +<p>If you examine a number of British butterflies you will observe +that in nearly all species the wings are bordered by a fringe of hair, +more or less distinct. But the case is different with <i>Cratægi</i>. Here +they are bordered by a black nervure, without any trace of fringe, +thus giving an amount of rigidity to the edges (see <a href="#Frontispiece">Plate I</a>, fig. 2).</p> + +<p>The wing rays, or nervures, are very distinct—a feature that<!-- Page 142 --><span class="pagenum"><a name="Page_142" id="Page_142">[Pg 142]</a></span> +gave rise to the popular name of the butterfly. In the male they +are quite or nearly black, but those of the fore wings of the female +are decidedly brown in colour. At the terminations of the wing +rays there are triangular patches of dark scales, the bases of which +unite on the outer margins of the wings.</p> + +<p>Another peculiar feature of this insect is the scanty distribution +of scales on the wings. This is particularly so in the case of the +female, whose wings are semi-transparent in consequence.</p> + +<p>The butterfly is on the wing during June and July, at which +time its eggs are laid on the hawthorn (<i>Cratægus Oxyacantha</i>) +or on fruit trees—apple, pear and plum.</p> + +<p>A vigorous search of these trees in the proper localities <i>may</i> +reveal to you a nest of the gregarious larvæ, all resting under the +cover of a common web of silk. These remain thus under their +silken tent throughout the hottest hours of the day, and venture out +to feed only during the early morning and in the evening.</p> + +<p>When the leaves begin to fall in the autumn, they construct a +more substantial web to protect themselves from the dangers of the +winter, and in this they hybernate till the buds burst in the +following spring. They now venture out, at first during the mildest +days only, and feed voraciously on the young leaves, returning to +their homes to rest. Soon, however, they gradually lose their +social tendencies, till at last, when about half or three-quarters +fed, they become quite solitary in their habits.</p> + +<p>In May they are fully grown, and change to the chrysalis state +on the twigs of their food trees.</p> + +<p>The larva is black above, with two reddish stripes. The sides +and under surface are grey, the former being relieved by black +spiracles.</p> + +<p>The pupa (<a href="#Page_45">page 45</a>) is greenish or yellowish white, striped with +bright yellow, and spotted with black.</p> + +<p>It is probable that the reader will never meet with this insect in +any of its stages. But, though it may have left us, it is still very +abundant on the Continent, where it does great damage to fruit +trees; and the foreign pupæ may be purchased of English +dealers.</p> + + +<h4><i>The Large White</i> (<i>Pieris Brassicæ</i>)</h4> + +<p>We pass now from one of the rarest to one of the most abundant +of British butterflies. Everybody has seen the 'Large White,' +though we doubt whether everybody knows that this insect is not<!-- Page 143 --><span class="pagenum"><a name="Page_143" id="Page_143">[Pg 143]</a></span> +of the same species as the two other very common 'Whites.' The +three—Large, Small, and Green-veined—are so much alike in +general colour and markings, and so similar in their habits and in +the selection of their food plants, that the non-entomological, not +knowing that insects do not grow in their perfect state, may +perhaps regard the larger and the smaller as older and younger +members of the same species. But no—they are three distinct +species, exhibiting to a careful observer many important marks by +which each may be known from the other two.</p> + +<p>On <a href="#Frontispiece">Plate I</a> (fig. 3) will be seen a picture of the female <i>Brassicæ</i>, +in which the following markings are depicted: On each fore wing—a +blotch at the tip, a round spot near the centre, another round +one nearer the inner margin, and a tapering spot on the inner margin +with its point toward the base of the wing. On the hind wings +there is only one spot, situated near the middle of the costal +margin.</p> + +<p>The male may be readily distinguished by the absence of the +black markings on the fore wings, with the exception of those +at the tips. He is also a trifle smaller than his mate.</p> + +<p>This butterfly is double-brooded. The first brood appears in +April and May, the second in July and August; and the former—the +spring brood—which emerges from the chrysalides that have +hybernated during the winter, have <i>grey</i> rather than black tips to +the front wings.</p> + +<p>The ova of <i>Brassicæ</i> may be found on the leaves of cabbages in +every kitchen garden, also on the nasturtium, during May and +July. They are pretty objects (see <a href="#FIG_10">fig. 10</a>), something like little +bottles or sculptured vases standing on end, and are arranged +either singly or in little groups.</p> + +<p>As soon as the young larvæ are out—from ten to fifteen days +after the eggs are deposited—having devoured their shells, they +start feeding on the selfsame spot, and afterwards wander about, +dealing out destruction as they go, till little remains of their +food plant save the mere stumps and skeletons of the leaves.</p> + +<p>The ground colour of the caterpillar is bluish green. It has a +narrow yellow stripe down the middle of the back, and two similar +but wider stripes along the sides; and the surface of the body is +rendered somewhat rough by a number of small black warty projections, +from each of which arises a short hair.</p> + +<p>When fully grown, it creeps to some neighbouring wall or +fence, up which it climbs till it reaches a sheltering ledge. Here<!-- Page 144 --><span class="pagenum"><a name="Page_144" id="Page_144">[Pg 144]</a></span> +it constructs its web and silken cord as already described (page 36), +and then changes to a bluish-white chrysalis, dotted with black. +The butterflies of the summer brood emerge shortly after, but +the chrysalides of the next brood hybernate till the following +spring.</p> + +<p>It is remarkable that we are so plagued with 'Whites' seeing +that they have so many enemies. Many of the insect-feeding birds +commit fearful havoc among their larvæ, and often chase the +perfect insects on the wing, but perhaps their greatest enemy is the +ichneumon fly.</p> + +<p>Look under the ledges of a wall of any kitchen garden, and you +will see little clusters of oval bodies of a bright yellow colour. +Most gardeners know that these are in some way or other +connected with the caterpillars that do so much damage to their +vegetables. They are often considered to be eggs laid by the +larvæ, and are consequently killed out of pure revenge, or +with a desire to save the crops from the future marauders.</p> + +<p>No greater mistake could be made. These yellow bodies are +the silken cocoons of the caterpillar's own foes. They contain the +pupæ of the little flies whose larvæ have lived within the body of +an unfortunate grub, and, having flourished to perfection at the +expense of their host, left its almost empty and nearly lifeless +carcase to die and drop to the ground just at the time when it +ought to be working out its final changes. Often you may see the +dying grub beside the cluster of cocoons just constructed by its +deadly enemies. Should you wish to test the extent of the +destructive work of these busy flies, go into your garden and collect +a number of larvæ, and endeavour to rear them under cover. The +probability is that only a small proportion will ever reach the +final state, the others having been fatally 'stung' before you took +them.</p> + + +<h4><i>The Small White</i> (<i>P. Rapæ</i>)</h4> + +<p>This butterfly closely resembles the last species except in point +of size. The male, represented on <a href="#Frontispiece">Plate I</a> (fig. 4), has a dark grey +blotch at the tip of each fore wing, a round spot of the same colour +beyond the centre of that wing, and another on the costal margin +of the hind wing. The female may be distinguished by an +additional spot near the anal angle of the fore wing.</p> + +<p>Although this and the two other common butterflies (<i>Brassicæ</i> +and <i>Napi</i>) that frequent our kitchen gardens are usually spoken of<!-- Page 145 --><span class="pagenum"><a name="Page_145" id="Page_145">[Pg 145]</a></span> +as 'Whites,' a glance at a few specimens will show that they are +not really white at all, but exhibit delicate shades of cream and +yellow, inclining sometimes to buff. The under surfaces are particularly +noticeable in this respect, for here the hind wings and the +tips of the fore wings display a very rich yellow.</p> + +<p>The species we are now considering is also very variable both in +its ground colour and the markings of the wings. The former is in +some cases a really brilliant yellow; and the latter are in some +cases entirely wanting.</p> + +<p><i>Rapæ</i> is double-brooded, the first brood appearing in April and +May, and the other in July and August.</p> + +<p>During these months the eggs may be seen in plenty on its +numerous food plants, which include the cabbages and horse-radish +of our gardens, also water-cress (<i>Nasturtium officinale</i>), rape +(<i>Brassica Napus</i>), wild mustard (<i>B. Sinapis</i>), wild mignonette +(<i>Reseda lutea</i>), and nasturtium (<i>Tropæolum majus</i>).</p> + +<p>The eggs are conical in form—something like a sugar loaf, with +ridges running from apex to base, and very delicate lines from +ridge to ridge transversely.</p> + +<p>The young larvæ often make their first meal of the shell, and +then attack the food plant so voraciously that they are fully grown +in about three or four weeks. In colour they are of a beautiful +glaucous green, hardly distinguishable at times from the leaves on +which they rest. A yellow stripe runs along the middle of the +back, and lines of yellow spots adorn the sides; and the whole body +is covered with very short hairs, each one arising from a minute +warty projection.</p> + +<p>The pupæ may be found during the same seasons and in the +same situations as those of <i>Brassicæ</i>. They are very variable in +colour. Some are of a very pale grey or putty colour, some are +decidedly brown, and others of a greenish tinge; and they are +often spotted and striped with dark grey or black.</p> + + +<h4><i>The Green-veined White</i> (<i>P. Napi</i>)</h4> + +<p>A non-observant beginner at entomological work may easily +mistake this insect for the last species, for the ground colour and +markings are very similar, even to the features by which the sexes +are distinguished from each other; but an inspection of the under +surface will give a ready means of identification, for here the wing +rays are bordered with black scales which, by contrast with the<!-- Page 146 --><span class="pagenum"><a name="Page_146" id="Page_146">[Pg 146]</a></span> +rich yellow around them, often appear of a greenish hue. The +butterfly receives its popular name from this circumstance.</p> + +<p>A careful observer, however, will readily find distinguishing +marks on the upper side, for here also the chief 'veins' are more +or less accompanied with black scales, especially the extremities of +those of the fore wings, where little triangular blotches are often +distinctly formed; and the dark veining of the under surface of the +hind wings frequently shows through. The under side of this +insect is shown on <a href="#Frontispiece">Plate I</a> (fig. 5).</p> + +<p>This butterfly is not so abundant as the two preceding, but is +widely distributed throughout England, and is in most parts +decidedly plentiful.</p> + +<p>The first brood (for it also is double-brooded) appears during +April and May, and the second in July and August.</p> + +<p>The eggs are very similar to those of <i>Rapæ</i>, resembling ribbed +and striated sugar loaves; and the larvæ are of the same rich glaucous +green, but may be identified by the black spiracles surrounded by +yellow rings. In our gardens we may find both eggs and larvæ on +mignonette and horse-radish; the other food plants of this species +include the water-cress (<i>Nasturtium officinale</i>), winter cress +(<i>Barbarea vulgaris</i>), rape (<i>Brassica Napus</i>), cuckoo-flower +(<i>Cardamine pratensis</i>), and Jack-by-the-hedge (<i>Sisymbrium +Alliaria</i>).</p> + +<p>The pupa is greenish, and marked with small black dots.</p> + + +<h4><i>The Bath or Green-chequered White</i> (<i>P. Daplidice</i>)</h4> + +<p>There is no doubt that many butterflies migrate from one country +to another across the seas; and as the Bath White is very +common on the other side of the Channel, and has been taken very +sparingly in England almost exclusively in the south-east, it is +highly probable that the majority of those that have been captured +here are specimens that have taken a voluntary trip across the +water, or have been blown over during rough weather.</p> + +<p>This butterfly is one of our greatest rarities, and the capture of a +specimen in England is an event that must necessarily be recorded +in our entomological literature. It seems that <i>Daplidice</i> has bred +in England, for its caterpillars have been found at large on one or +two occasions, so I will give a short description of the various +stages of the insect, with a hope that some of my readers may be +fortunate enough to meet with it.<!-- Page 147 --><span class="pagenum"><a name="Page_147" id="Page_147">[Pg 147]</a></span></p> + +<p>The female butterfly is shown on <a href="#Frontispiece">Plate I</a>, fig. 6. From this it +will be observed that each of the fore wings is tipped with a rather +large smoky-black blotch, in which are four white spots. A double +spot of the same colour also occupies a place near the centre of the +wing, and another smaller and round one lies near the anal angle. +The hind wings are clouded with grey, and bordered along the +hind margin with distinct smoky-black spots.</p> + +<p>The male may be distinguished from the female by the absence +of the spot near the anal angle of the fore wings, and of all the +clouds and spots of the hind wings. Nevertheless the latter have +a decidedly clouded appearance, but this is due to the markings of +the under surface showing through them.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_65" id="FIG_65"></a><a href="images/i_164.jpg"><img src="images/i_164_tn.jpg" width="300" height="137" alt="" title="Linked to larger image of The Bath White." /></a> +<span class="caption">Fig. 65.—The Bath White—Under +Side.</span> +</div> + +<p>The under side of both sexes is most beautifully marked—the +fore wings resembling the upper sides, but the hind pair chequered +with a beautiful soft green on a +pale yellow ground.</p> + +<p>The eggs of this insect are +deposited during April and May, +and again in August or September—for +it is, like the other +'Whites,' double-brooded—on +two species of Wild Mignonette +(<i>Reseda lutea</i> and <i>R. luteola</i>).</p> + +<p>The caterpillars, which are +of a bluish colour, with two +yellow stripes down the back, and +two others along the sides, may be <i>looked</i> for in June and September. +Those of the first brood only have been taken in this +country, while the others on the Continent change to the chrysalis +in the autumn, and hybernate in this state throughout the winter.</p> + +<p>The chrysalis is of a brownish colour, and closely resembles that +of the Small White in form.</p> + +<p>Those in search of this rare British insect should wander along +the south-east coast, and net all the doubtful slow-flying small +Whites (<i>Daplidice</i> is rather slow and heavy on the wing), and +their perseverance <i>may</i> be rewarded with a prize that will ever be +a reminder of a glorious catch and an eventful day.

The female +is usually a little larger than her mate, and is marked similarly on +both sides except that the bright orange blotch is entirely wanting. +She may always be distinguished from <i>Daplidice</i> by the smaller +size of the white spots that break the dark blotch at the tip of the +fore wing; also by the very small size of the dark spot in the +centre of the same wing. The green chequerings of the under side +of the hind wings are also more sharply defined, and the insect is +generally of a lighter build.</p> + +<p>Like many other butterflies, the Orange Tip is subject to variations +in colouring. Sometimes a pale but bright yellow takes the +place of the white ground, and the orange blotch of the male is +occasionally present on the upper or lower surface only.</p> + +<p><i>Cardamines</i> is a single-brooded insect, and is essentially a +creature of the spring, at which time it may be found in abundance +in lanes, meadows, and clearings in woods throughout the British +Isles. Its flight is so light and airy that even the female may +easily be distinguished from other Whites when on the wing, while +the brilliant orange of the male, intensified by the bright rays of +the spring sun, may be identified at some considerable distance.</p> + +<p>The food plants of <i>Cardamines</i> include the cuckoo-flower +(<i>Cardamine pratensis</i>) and the bitter cress (<i>C. impatiens</i>), after +which the insect is named, also water-cress (<i>Nasturtium officinale</i>), +winter cress (<i>Barbarea vulgaris</i>), rock cress (<i>Arabis perfoliata</i>), +hedge mustard (<i>Sisymbrium officinale</i>), Jack-by-the-hedge (<i>S. +Alliaria</i>), wild mustard (<i>Brassica Sinapis</i>), &c., and the eggs of +the butterfly may be found on these during May and June.</p> + +<p>The caterpillar (<a href="#Plate_VIII">Plate VIII</a>, fig. 2) is green, with a white stripe +on each side, and its body is covered with short hair.

Both +ends are much elongated and sharply pointed; and the foremost +extremity stands out at an angle with the stem to which it is +attached.</p> + +<p>This butterfly should be looked for during April and May, but in +mild seasons it may often be met with in March.</p> + + +<h4><i>The Wood White</i> (<i>Leucophasia Sinapis</i>)</h4> + +<p>The distinguishing feature of this butterfly (see <a href="#Plate_II">Plate II</a>, fig. 1) +is the extreme lightness and delicacy of its build. Its wings are +narrow, and rounded at the tips; and the only mark to relieve the +white ground of the upper side is a squarish blotch at the tip of the +fore wing, and even this is either very indistinct or entirely absent +in the female. The under surface is clouded with a pale greenish +tint.</p> + +<p>This insect may be looked for in May and again in August, in +paths and clearings in woods, where it moves along with a slow but +steady flight, hardly ever seeming to rest for a moment. It is not +by any means a common butterfly, but is very widely distributed, +and sometimes appears in considerable numbers in certain favoured +spots. Among the localities recorded may be mentioned Torquay, +Exeter, Plymouth, South Dorset, New Forest, Reading, Darent +Woods, Morecambe Bay, Haslemere, Windermere, &c.</p> + +<p>The caterpillar is of a beautiful green colour, and is covered with +short whitish hairs. A darker green stripe runs down the middle +of the back, and a bright yellow stripe along each side. Its food +plants are the tufted vetch (<i>Vicia Cracca</i>), bird's-foot trefoil (<i>Lotus +corniculatus</i> and <i>L. pilosus</i>), bitter vetch (<i>Lathyrus tuberosus</i>), +and the everlasting pea (<i>L. sylvestris</i>).</p> + +<p>The chrysalis is a very beautiful object.

It is particularly fond of lucerne and clover fields, +especially those that are situated close to the sea cliffs; and often +it may be seen flying over the beach, sometimes even flitting over +the breakers away from land till at last it disappears in the distance. +This maritime tendency of <i>Hyale</i> makes it probable that a +large number of those that are seen on our south-east coasts have +made a passage across the narrow end of the Channel.</p> + +<p>The eggs are laid in spring, by females that have hybernated +throughout the winter, on various leguminous plants, including the +lucerne (<i>Medicago sativa</i>), black medick (<i>M. lupulina</i>), purple and +Dutch clovers (<i>Trifolium pratense</i> and <i>T. repens</i>), and the bird's-foot +trefoil (<i>Lotus corniculatus</i>), and on these plants you may search +for the larva, though it can scarcely be said that you are likely to +find it.</p> + +<p>The caterpillar is green, with black dots, and a yellowish stripe +on each side. When fully grown it ascends a stem of its food plant +and changes to a green chrysalis with yellow stripes.</p> + +<p><i>Hyale</i> is single-brooded in England, although two broods +regularly appear on the Continent. In our country the perfect insects +emerge during July and August. Many of these die before +the approach of winter; but, as we have already observed, some +hybernate and deposit their eggs in the following spring.<!-- Page 151 --><span class="pagenum"><a name="Page_151" id="Page_151">[Pg 151]</a></span></p> + + +<h4><i>The Clouded Yellow</i> (<i>Colias Edusa</i>)</h4> + +<p>Not only are this and the last species similarly named, but a +glance at the figures will show that they much resemble each other +in appearance; and we shall also learn presently that in their habits +and life history they have much in common.</p> + +<p>The male <i>Edusa</i> is shown on <a href="#Plate_II">Plate II</a> (fig. 3), and when we +compare it with its relative on the opposite side, we are at once struck +with the superior richness of the brilliant orange or saffron of the +ground colour.

The last favoured +season was the summer of '92, during which (from the beginning of +August to the end of the summer) dozens might easily have been +caught in an hour or two; in fact, so plentiful were they in many +places, that they were continuously in sight, often several at one time.</p> + +<p>Those in search of this insect should repair to the south coast, +especially the south-east, and where lucerne and clover fields are +in flower. It has very decided maritime tendencies, and may often +be seen flying over the cliffs and beaches, and even skipping over the +breakers; but, at the same time, it is more or less plentiful in many +inland districts. It has been taken in many parts of Ireland and +Scotland, particularly along the southern coasts of these countries; +but its head quarters are undoubtedly the southern cliffs of England, +from Cornwall to Kent, and also the hilly inland districts of the +south-eastern counties.</p> + +<p><i>Edusa</i> catching is very lively sport, and is likely to prove +sufficient for any lover of outdoor exercise under a scorching sun; +for this butterfly is not only very powerful on the wing, but its +flights are usually long, so that a good run is often absolutely +necessary in order to capture it. On very hilly ground, such as +<i>Edusa</i> loves, chase is often hopeless, and then it is necessary to +resort to stratagem. In such a case the best plan is to make a +very cautious approach when the insect has been observed to settle, +and then secure it with a sudden down-stroke of the net.</p> + +<p>The eggs are laid during May and June by a few females that +have survived the winter.</p> + +<p>The caterpillar may be found in June and July on its food +plants, the chief of which are the bird's-foot trefoil (<i>Lotus corniculatus</i>), +and the purple and Dutch clovers (<i>Trifolium pratense</i> and +<i>T. repens</i>).

The costal margins of the fore +pair are most beautifully arched, and both pairs are sharply angled +on the hind margins.

That of the female is a very +pale greenish yellow. The only conspicuous markings are small +saffron spots, one near the centre of each wing. The antennæ are +red, short, and beautifully curved; but, unlike the two preceding +species, the legs are almost white.</p> + +<p>The eggs of this butterfly are laid in April on the two species of +buckthorn (<i>Rhamnus catharticus</i> and <i>R. Frangula</i>) by the females +that have successfully weathered the winter. They are of a bright +yellow colour, and are usually hatched in about a fortnight.</p> + +<p>The body of the caterpillar is green, and it is thickly covered +with little black wart-like projections. A pale stripe also runs +along each side. During May and June it may be found on its +food plants, and toward the end of the latter month it attaches itself +by a silken carpet and belt to the under side of one of the leaves.</p> + +<p>The chrysalis is of a very peculiar shape, the body being curved, +and the wing cases standing out prominently beyond the general +surface. Its colour is a bright apple green marked with yellow, +and it is so transparent that certain of the structures can be seen +through its skin.</p> + +<p>The perfect insect emerges in about three weeks after the change +to the chrysalis; and may be looked for from July to the end of the +summer. This period may be regarded as the best time in which +to hunt for <i>Rhamni</i>, but it is to be noted that this butterfly makes +its appearance during all months of the year, even though it is single-brooded.</p> + +<p>A large number seem to hybernate, and their winter sleep is so +light that the welcome rays of the sun on a mild day, even during +the bleak months of November to February, will often call them out +from their hiding places. Then, as a rule, the hybernating butterflies +do not live long after depositing their eggs for the future +brood; but the Brimstone often lives on till its offspring have themselves +attained the perfect state, so that it is possible to capture the +insects of two different years both on the same day. In such a case +it is generally easy to distinguish between the two, for the newly +emerged specimens are beautifully bright and fresh in colour, +while those of the previous year are more or less faded and worn, +their wings being often semi-transparent through the loss of scales, +and frequently disfigured by the stains of mildew.</p> + + + +<hr /> +<p><!-- Page 154 --><span class="pagenum"><a name="Page_154" id="Page_154">[Pg 154]</a></span></p> +<h3><a name="CHAPTER_XIII" id="CHAPTER_XIII"></a>CHAPTER XIII +<br /> +<i>THE FRITILLARIES, VANESSAS, AND THE PURPLE +EMPEROR</i></h3> + + +<h4>Family—<span class="smcap">Nymphalidæ</span></h4> + +<p>We now come to a rather large family, which contains some of our +largest and most brilliant butterflies.

A slight examination +of a few in their different stages will show that this is so. +Thus, the perfect insects have only four walking legs, the caterpillars +are all spiny, and the chrysalides are angular.</p> + +<p>There is another feature concerning the chrysalides worthy of +note.

The continental specimens may be easily distinguished +from the genuine Britishers by a darker border with a +decidedly yellow tinge.</p> + +<p>The eggs of this species are generally laid on the young leaves of +the willow (<i>Salix alba</i>), in the spring, by females that have hybernated, +but sometimes the nettle (<i>Urtica dioica</i>) and the birch +(<i>Betula alba</i>) are selected for the food of the larvæ.</p> + +<p>The caterpillar is black and spiny, and has a row of seven rather +large reddish-brown spots on the back, commencing at the fifth +segment.</p> + +<p>The chrysalis, like those of the other members of this family, +is angular and suspended by the 'tail.' The perfect insect appears +in August, and may be seen from that month till October.</p> + + +<h4><i>The Red Admiral</i> (<i>Vanessa Atalanta</i>)</h4> + +<p>There seems to be a tendency with many to under-estimate the +beauty of certain natural objects because they happen to be so very +common, and this is particularly the case with some of our most +familiar butterflies. The beautiful Red Admiral (<a href="#Plate_IV">Plate IV</a>, fig. 3) +may possibly suffer in this respect; for, not only is it one of the +commonest of our butterflies, but it fearlessly hovers among the +flowers of our gardens, often venturing into the very heart of thickly +populated towns.</p> + +<p>The bright scarlet bands and white blotches of this gorgeous +insect stand out boldly on the rich velvety black ground of the +wings, and the additional touches of blue in the anal angles of the +hind wings add to the effect. The under side of the fore wings is +somewhat similar to the upper surface, but is relieved by brown +and blue; and this side of the hind wings presents most beautiful +and indescribable blendings of various shades of brown, grey, and<!-- Page 169 --><span class="pagenum"><a name="Page_169" id="Page_169">[Pg 169]</a></span> +pink. The female may be distinguished by the presence of a small +white spot on the scarlet band of the fore wing.</p> + +<p>The eggs are deposited singly on the nettle (<i>Urtica dioica</i>) in +spring by females that have hybernated through the winter.</p> + +<p>The caterpillar always feeds under the cover of a tent made by +drawing leaves together. It is spiny, and its colour is usually a +greenish or yellowish grey, spotted with black, and striped along +the sides with white or yellow. When fully grown it bites the stem +of the nettle nearly through a few inches from the top, so that the +upper part of the plant bends over the withers. It then constructs +a commodious tent by binding the leaves of this drooping portion +together, and suspends itself from the roof of this strange home to +undergo its metamorphoses.</p> + +<p>The change to the chrysalis state takes place in July or August, +and the perfect insect may be seen during August, September, +and October in almost every part of the British Isles.</p> + + +<h4><i>The Painted Lady</i> (<i>Vanessa Cardui</i>)</h4> + +<p>Although the time of appearance of this butterfly generally +corresponds with that of the last species, yet it is exceedingly +variable, so much so that it is impossible to give any fixed period +as its season. It is, moreover, very capricious with regard to its +localities and its numbers. Sometimes it will turn up unexpectedly +in positive abundance in certain localities where +previously it had been a mere straggler; and then, for some +unaccountable reason, become comparatively scarce for several +successive seasons.</p> + +<p>The upper surface of this beauty (<a href="#Plate_IV">Plate IV</a>, fig. 4) is adorned +with pale red, orange, and black, and with five white spots near +the tip of each fore wing. The under side of the fore wings is +marked something like the upper, but much of the black is replaced +by shades of brown. The hind wings are beautifully variegated +beneath with greys and browns, and have a row of eye-like spots +near the hind margin.</p> + +<p>The eggs of this butterfly are laid singly on various species of +thistles, particularly the common field thistle (<i>Cnicus arvensis</i>), +generally in the month of June.</p> + +<p>The caterpillar, which is black above and red beneath, with +yellowish stripes along the back and sides, feeds under the cover of a +silken web which it constructs among the leaves. It is full grown<!-- Page 170 --><span class="pagenum"><a name="Page_170" id="Page_170">[Pg 170]</a></span> +in July or August, when it suspends itself after the manner of the +other Vanessas previous to undergoing its changes.</p> + +<p>The chrysalis is angular, coloured with brown and grey, and +adorned with brilliant gold spots.</p> + +<p>The perfect insect may be seen at large throughout late summer +and the autumn, and the eggs are laid by females that survive the +winter.</p> + + +<h4><i>The White Admiral</i> (<i>Limenitis Sibylla</i>)</h4> + +<p>The White Admiral (<a href="#Plate_IV">Plate IV</a>, fig. 5) is neither so pretty nor so +common as its red namesake, but it is nevertheless a fine insect, +although the chief beauty is reserved for the under surface. Above, +the ground colour is a very dark rusty brown, relieved by bands +and spots of white. The under surface is beautifully marked with +silvery blue, bright orange brown, and white, the latter being +arranged just like the corresponding colour on the upper side.</p> + +<p>It will be observed that this butterfly does not belong to the +<i>Vanessa</i> genus; so, while we may look for <i>family</i> resemblances, +we shall observe a few features in which it differs from the preceding +species.</p> + +<p>It is not by any means abundant, being unknown in Scotland +and Ireland, and confined in England almost exclusively to the +oak woods of the south, where its food plant—the honeysuckle +(<i>Lonicera Periclymenum</i>)—abounds. Here it may be seen during +July, gracefully sailing among the trees and across the open spaces.</p> + +<p>The caterpillar is very different from those of the Vanessas. +Its colour is dark green, with a narrow white stripe along each +side. There are very conspicuous branched spines on the third and +two following segments, also on the eleventh and twelfth; and +smaller spines on most of the others. All the spines are of a +brownish colour, with pink tips. While it is yet very small it prepares +its winter quarters by bending round the remains of a leaf on +which it has been feeding, securing the edges by silken threads, +and then binding it to the stem of the plant. Soon after, the petiole +becomes detached from the stem, and the little caterpillar then +rests suspended in its snug swinging cradle, where it remains +perfectly secure till the following April, when the warm sun calls +it out to feed on the opening leaves. It continues at this till about +the beginning of June, and then changes to a beautiful angular and +eared chrysalis, of a bright green colour, marked with brown, and +having brilliant silvery spots and streaks.<!-- Page 171 --><span class="pagenum"><a name="Page_171" id="Page_171">[Pg 171]</a></span></p> + + +<h4>Family—<span class="smcap">Apaturidæ</span><br /> +<br /> +<i>The Purple Emperor</i> (<i>Apatura Iris</i>)</h4> + +<p>This grand insect is the only British member of its family, and +richly deserves its popular title. The male, which is figured on +<a href="#Plate_V">Plate V</a> (fig. 1), exhibits a most gorgeous imperial purple, which is +reflected at certain angles only from the upper surface of his large +and powerful wings. His flight is lofty and vigorous, and among +the topmost branches of majestic oaks, where he defies the efforts +of would-be capturers. Unlike our other butterflies, he is also a +very quarrelsome creature, and will not hesitate to fiercely attack +a brother Emperor who dares approach the branch he has selected +for his throne.</p> + +<p>Many attempts have been made to capture this prized creature +by means of a large net mounted on the end of a pole twenty or +thirty feet in length, but the wielding of such a cumbersome implement +against so powerful an insect is no mean task, and but few +fall a prey to such a snare. But it so happens that this imperial +personage has a very depraved appetite, the indulgence in which +has often brought him to ruin. Instead of searching out the sweets +so bounteously supplied by the blossoms that are so attractive to +other lepidopterous insects, he delights in sipping the waters of the +filthiest puddles, and imbibing the odoriferous moisture of dung and +the decomposing carcases of animals. So deeply seated is this depravity +of taste that the Emperor may be netted with ease while +indulging in his sumptuous feast, and is even to be taken at times +with the fingers.</p> + +<p>The knowledge of this peculiarity of the imperial palate has led +entomologists to abandon the awkward net, and to bait the woods +with viands that alone can entice his highness from his lofty seat; +and many a splendid specimen has been easily captured while +enjoying the luxurious juice of a dead cat, stoat, or rabbit, or of a +seething mass of pig's dung.</p> + +<p>The female is larger than her mate, and does not display the +beautiful purple reflections that adorn the male. She is very +different, too, in her habits, for she sits nearly all day on high +branches of trees, giving her attention to the graver duties of an +imperial mother, and is consequently but seldom seem. She lays +her eggs in July on the sallow (<i>Salix Caprea</i>) or the poplar (<i>Populus</i>), +and in less than a fortnight the young caterpillars are hatched.<!-- Page 172 --><span class="pagenum"><a name="Page_172" id="Page_172">[Pg 172]</a></span> +They feed on till the leaves are falling, and then fix themselves by +their claspers to a silken carpet which they construct on a twig.

Its chief +haunts are the waste cliffy grounds of the southern and some of +the midland counties of England, where it is usually restricted to certain +small districts. In some places it is really a common insect, +and among these may be mentioned Brighton, Horsham, Dover, +Folkestone, Margate, +Gravesend, New Forest, +parts of Gloucestershire, +Cambridgeshire, and +Devonshire, also in the +Isle of Wight and South +Wales.</p> + +<p>The perfect insect is +out in July, during which +month the eggs are deposited +on various grasses, +or indiscriminately on +leaves and stems in grassy +spots.</p> + +<p>The caterpillar feeds on grasses; and, being still small at the +end of the autumn, hybernates during the winter among the stems of +grass. It feeds again in April, and is fully grown by the end of May. +Its colour is a dull green or brownish, with a darker stripe down +the back, and lighter stripes along the sides. Its spiracles are black.</p> + +<p>The chrysalis is pale brown, marked with lines of a slightly +darker shade. It may be found among grass stems, without any +attachment, during the month of June.</p> + + +<h4><i>The Small Ringlet</i> (<i>Erebia Epiphron</i>)</h4> + +<p>On account of the very limited range of this butterfly, only those +who have the opportunity of visiting its haunts can have any +practical acquaintance with its natural history. It is almost +exclusively confined to the lake district in England, to a few +mountainous localities in Scotland, and to one or two similar +localities in Ireland. Its strong partiality for elevated situations +has earned for it the popular name of Mountain Ringlet.</p> + +<p>The colour of the upper surface (<a href="#Plate_V">Plate V</a>, fig. 3) is a dark +brown, with a broad band of rusty brown, parallel with the hind +margin of each wing, and broken by the wing rays. Each division<!-- Page 175 --><span class="pagenum"><a name="Page_175" id="Page_175">[Pg 175]</a></span> +of these bands has often a black central spot, but frequently these +are entirely absent. The colouring of the under side is very +similar but less defined, and the rusty spots of the hind wings are +very small.</p> + +<p>The butterfly is out in June and July. The caterpillars, which +are green, with white stripes along the sides, feed on various +grasses. They hybernate during the winter, and change to the +chrysalis state in the following May or June.</p> + + +<h4><i>The Northern Brown</i> (<i>Erebia Æthiops</i>)</h4> + +<p>The colour of this species (<a href="#Plate_V">Plate V</a>, fig. 4) is a rich dark brown, +with rust-coloured and black spotted bands arranged something +like those of the last. The markings, however, are very variable. +There are usually four black spots on the band of the fore wings, +but the first two of these are always united, and centred with +white. The third is often very small or entirely wanting.</p> + +<p>The under side of the fore wings is marked something like the +upper, but the hind wings on this side are grey, with two broad +bands of a darker colour.</p> + +<p>As its popular name implies, this butterfly is a northerner. It +is common in Scotland, where it flies in elevated spots. In +England it is confined to the mountainous districts of the +north.</p> + +<p>The perfect insect is at large in July and August, during which +time the eggs are deposited on various grasses or on low-growing +herbage in grassy spots.</p> + +<p>The caterpillar is of a brown colour, and has a narrow black +stripe down the middle of the back, and two other stripes, lighter +than the ground colour, one on each side.

This fact is +particularly noticeable on a bright day with occasional heavy +clouds. While the sun's rays are pouring uninterruptedly on the +landscape, numbers of these light-lovers are to be observed flitting<!-- Page 176 --><span class="pagenum"><a name="Page_176" id="Page_176">[Pg 176]</a></span> +about; but when the dense shadow of a passing cloud creeps over +the ground they rapidly disappear from view, having settled down +to rest on leaves and stems. Then, as soon as the shadow passes +away, the air is again enlivened with their sports and flittings.</p> + +<p>The Wood Argus is a marked exception to this rule. It +delights in the cool shade of the narrow paths of woods, where it +slowly flies up and down the lonely footpath, taking but little heed +of strangers that intrude on its haunts, and seldom venturing into +the full blaze of the sun unless pursued. Even on dull days it +continues its solitary flight, and may even be seen on the wing +while a soft rain is bathing the dripping foliage.</p> + +<div class="figright" style="width: 300px;"> +<a name="FIG_78" id="FIG_78"></a><a href="images/i_193.jpg"><img src="images/i_193_tn.jpg" width="300" height="101" alt="" title="Linked to larger image of The Wood Argus." /></a> +<span class="caption">Fig. 78.—The Wood Argus—Under +Side.</span> +</div> + +<p>The upper surface of this pretty butterfly is shown on <a href="#Plate_V">Plate V</a>, +fig. 5, and the under side in the accompanying woodcut.

I have +seen it actively flying about during August, as early as 7.30 in the +morning, and found it still flitting from one spot to another along +the western side of a wall as late as 8 in the evening, as if in search +of a convenient shelter for the fast approaching night.</p> + +<p>This pretty 'Brown' must be familiar to the reader, and the +coloured drawing on <a href="#Plate_V">Plate V</a> (fig. 6) will at once serve for purposes +of identification without the necessity of a wordy description. It +may be mentioned, however, that the male (the sex figured) is +smaller than the female, and is further distinguished by a broad dark +oblique band passing across each fore wing.</p> + +<p>The Wall is a double-brooded butterfly, the first brood appearing +in May, and the second in August. The caterpillars which produce +the latter may be found on the cock's foot (<i>Dactylis glomerata</i>) +and other grasses in June, while those of the former are hybernators; +and the chrysalides of the two broods may be found in April +and July respectively.</p> + +<p>The colour of the caterpillar is green, with a slightly darker +stripe down the middle of the back, a pale stripe along each side, +and another similar stripe about midway between these two.</p> + +<p>The chrysalis is green with the exception of the more prominent +parts of its surface, which are almost white.</p> + +<p>This species is very common in almost every locality in Britain.</p> + + +<h4><i>The Grayling</i> (<i>Satyrus Semele</i>)</h4> + +<p>The Grayling is the largest of our 'Browns,' and, although a +powerful flier, it seldom takes long flights. The female, which is +shown in fig. 7, <a href="#Plate_V">Plate V</a>, is really a beautiful creature, the light +markings of which stand out in bold contrast with the deep brown +ground colour; but the male is comparatively dingy, there being +much less contrast between the ground and the markings.

The former is of a brilliant copper hue, and all the wings +have a black margin and a black streak near the middle. The female +is larger; and the coppery colour is much redder.

There are also numerous black spots in light +rings, the arrangement of which will be seen in the figure.</p> + +<p>Some species of butterflies and moths are so variable in their +colouring and markings that varieties have often been mistaken for +distinct species; and, in other cases, distinct species are sometimes +so similar in character that they are looked upon as identical.</p> + +<p>A butterfly that closely resembles the normal Brown Argus in +many points, and named <i>Artaxerxes</i>, has often been described as a +distinct species, but is now, I believe, recognised by most entomologists +as a constant variety of the present species.</p> + +<p>It differs from the normal type in having a <i>white</i> instead of a +<i>black</i> spot in the centre of the fore wings, and the border of orange +spots is often very indistinct. On the under side, too, instead of +black spots in white rings, it has white spots, with little or no trace +of a black centre.</p> + +<p>The ordinary Brown Argus is a southerner, and is particularly +abundant on the chalk downs of the south coast and the Isle of +Wight, but <i>Artaxerxes</i> is to be found only in Scotland and the +north of England; and it is interesting to note that, between these +northern and southern districts, intermediate varieties are to be met +with.</p> + +<p>Again, <i>Astrarche</i> is a double-brooded butterfly, appearing on +the wing in May and August; while <i>Artaxerxes</i> is single brooded, +flying at midsummer.

They are, nevertheless, very +interesting creatures, for they exhibit peculiarities of structure and +habit that render them singular among the butterflies, and seem to +show a sort of cousin relationship with the moths. They have +thick bodies that remind us somewhat of the <i>Noctuæ</i>. Their heads +are broad, so that the antennæ, which are slightly hooked at the +tips, are rather wide apart at the bases. When at rest, they +neither press their wings together over their back like the other +butterflies, nor do they set them horizontally after the manner of +the moths, but seem to lay claim to an intermediate position in the +scale of Lepidopterous insects by holding them in a half elevated +position. Their flight, too, is not graceful like that of most other +butterflies, nor even so steady as that of the little flitting blues, but +brisk and erratic, and resembling the fitful motions of moths disturbed +from their slumberings at unwonted hours. Thus they have +earned their popular title of skippers from their habit of skipping +rather than flying from flower to flower. All the three pairs of legs +of these butterflies are fully developed for walking.</p> + +<p>The caterpillars have rather large heads, and their bodies taper +from the middle toward both extremities. Like the larvæ of many +moths, they hide themselves in leaves which they have rolled and +secured with silken threads; and when about to change to the +chrysalis state, they also spin silken cocoons for their further +protection.</p> + + +<h4><i>The Grizzled Skipper</i> (<i>Syrichthus Malvæ</i>)</h4> + +<p>The ground color of this species is a very dark brown, relieved +by a number of square white spots arranged as shown in fig. 11 +of <a href="#Plate_VII">Plate VII</a>. The fringe is wide, and barred with the same two +colours, arranged alternately. The pattern of the under side is +similar, but the dark brown of the upper surface is replaced by a +lighter olive tint.</p> + +<p>The butterfly may be looked for in May in the open spaces of +woods, particularly in damp places. It is common all over England, +and is found also in the south of Scotland.</p> + +<p>The caterpillar is either green or brownish, with a darker dorsal +stripe of the same color, and two white lines on each side.

Occasionally, however, one of the +rarer species will be described in order to illustrate some striking +characteristic.</p> + +<p>We shall commence with the tribe of <i>Sphinges</i> or <i>Hawk +Moths</i>.<!-- Page 204 --><span class="pagenum"><a name="Page_204" id="Page_204">[Pg 204]</a></span></p> + +<p>This group consists of three families—the <i>Sphingidæ</i>, including +the largest of the 'Hawks,' and the 'Bee Hawks,' the <i>Sesiidæ</i> or +'Clearwings,' and the <i>Zygænidæ</i>, including the 'Foresters' and the +'Burnets'—numbering in all about forty species.</p> + + +<h4>Family—<span class="smcap">Sphingidæ</span></h4> + +<p>This family is named from a fancied resemblance of the larvæ +to the celebrated Egyptian sphinx. The perfect insects have very +thick bodies, generally tapering toward the tail, and their wings are +rather narrow in proportion to the length, but are exceedingly +powerful, and the flight is, with one or two exceptions, very rapid. +The antennæ terminate in a small and thin hook.</p> + +<p>Most of these insects fly at dusk, but a few delight in the brightness +and heat of the midday sun. In either case the velocity of +their flight is generally so great that it is a difficult matter to +follow them with the eye, and a still more difficult matter to secure +the insects in the net; consequently, the best way to study them is +to search out the larvæ on their food plants, and rear them till they +attain their perfect form.</p> + +<p>The larvæ of the <i>Sphingidæ</i> are large and smooth, and most of +them have a horn projecting from the top of the last segment but +one.

Its popular +title has been applied on account of the peculiar markings of the +thorax, which are said to resemble a human skull; and this feature +has certainly some connection with the superstitious beliefs of +ignorant country folk concerning this moth. But this characteristic +is probably not the only one that has caused the creature to +be regarded with superstitious alarm. Both its superior dimensions +and nocturnal habits serve to intensify the unfounded fear; but, +what is particularly striking and unique about it is its power of +uttering a squeaking sound, which it does when disturbed. Even +the earlier stages of the insect possess this strange power. The +caterpillar makes a peculiar snapping noise when irritated, and the<!-- Page 205 --><span class="pagenum"><a name="Page_205" id="Page_205">[Pg 205]</a></span> +chrysalis has been observed to squeak shortly before the emergence +of the perfect form.</p> + +<p>The fore wings of this moth are of a very rich dark brown, +beautifully mottled with lighter tawny shades, and with a small +but conspicuous yellow dot near the centre.

Its wings vibrate so rapidly that they are quite +invisible, and give rise to the soft hum already mentioned. Then +it darts from one flower to another, making a similar brief stay +before each while it sucks the grateful sweets. Raise your hand as +if to strike, and suddenly it vanishes you know not where. But it +is as bold as it is wary, and will often return to the selfsame flower +as if to defy your power. A sharp sweep of your net in a horizontal +direction, or a sudden downward stroke, <i>may</i> secure it; but if you +miss it, as you probably will, it will disappear like a phantom, and +give you no opportunity of making a second attempt.</p> + +<p>This moth is on the wing throughout the hottest months of the +year—May to September, and will often greet you as you roam over +flowery banks in search of butterflies.</p> + +<p>The caterpillar feeds on the lady's bedstraw (<i>Galium verum</i>), +hedge bedstraw (<i>G.

One +of these is the Mother Shipton, a very common insect that flies in +June.</p> + +<p>The fore wings of this species are very dark brown with whitish +markings. The latter include a peculiarly tortuous line, the character +of which will be made out more easily from our illustration (<a href="#Plate_XI">Plate +XI</a>, fig. 4) than from a written description. The hind wings are<!-- Page 265 --><span class="pagenum"><a name="Page_265" id="Page_265">[Pg 265]</a></span> +also very dark brown, and rather prettily spotted with an ochreous +tint.</p> + +<p>The caterpillar is pale grey, with four white stripes, and has +only three pairs of claspers. It feeds in May on clovers (<i>Trifolium +pratense</i> and <i>T. repens</i>) and other plants.</p> + + +<h4>Family—<span class="smcap">Catocalidæ</span></h4> + +<p>This family contains only four British species, but these few are +very striking moths. They are of large size; and, unlike the +<i>Noctuæ</i> generally, the chief adornment is reserved for the under +wings. When at rest, the outer or fore wings completely hide the +other pair, and then their general appearance is dull, though if +closely examined it will be observed that these outer wings are +really beautifully marbled with shades of grey.</p> + +<p>The caterpillars of this family are very peculiar creatures. Their +bodies are convex above and flattened beneath; and if disturbed +as they rest on the bark of a tree, instead of leaving their hold and +rolling into a ring like so many other larvæ of <i>Noctuæ</i>, they apply +themselves the closer, and hold on as if to defy our attempts to +remove them. Another peculiarity of these larvæ is the possession +of fleshy projections along the sides, just above the legs. They feed +on the leaves of trees, and when about to rest they descend to the +trunk, and there remain protected by their imitative colouring, +detection being rendered even more difficult by the close application +of their flattened under surface to the bark. Before changing +to the chrysalis state, they spin a light cocoon among the leaves or +on the bark.</p> + + +<h4><i>The Clifden Nonpareil</i> (<i>Catocala Fraxini</i>)</h4> + +<p>This is the largest of the family, and, indeed, of all British +<i>Noctuæ</i>. The fore wings and thorax are light grey, dotted and +marbled with darker grey (see fig. 5, <a href="#Plate_XI">Plate XI</a>); and the thorax +and abdomen are banded with black and greyish blue.</p> + +<p>The young entomologist can hardly expect to meet with this fine +insect, for it is very rare, and it is only occasionally that a specimen +is seen in Britain; but its characteristics are so striking that we have +endeavoured to find it a place here. Reputed British specimens of +<i>Fraxini</i> command the price of a few pounds each, but specimens +from the other side of the Channel may be obtained for a few pence. +With such rarities we should advise a young entomologist to purchase<!-- Page 266 --><span class="pagenum"><a name="Page_266" id="Page_266">[Pg 266]</a></span> +the foreign specimen rather than adopt the two other alternatives—give +an exorbitant price for a supposed Britisher, or else remain a +stranger to the gem, but all foreign specimens should be labelled +according to their nationalities.</p> + + +<h4><i>The Red Underwing</i> (<i>Catocala Nupta</i>)</h4> + +<div class="figright" style="width: 300px;"> +<a name="FIG_176" id="FIG_176"></a><a href="images/i_283.jpg"><img src="images/i_283_tn.jpg" width="300" height="147" alt="" title="Linked to larger image of The Red Underwing." /></a> +<span class="caption">Fig. 176.—The Red Underwing.</span> +</div> + +<p>The other three members of the family are very similar in +appearance, the fore wings of all being marbled with shades of +grey, relieved by touches of black and brown; and the hind wings, +red or crimson, give the popular names to the species.</p> + +<p>The Red Underwing flies in August and September, and is +common in the southern counties of England, as well as in some +of the midland counties; it may be often seen flying by day +around willows.</p> + +<p>The caterpillar is similar in form to that of <i>Fraxini</i>, and when +at rest by day on the bark of its tree it is very difficult to detect, so +closely does it apply itself to the surface, and so perfectly does it +imitate the colour of its surroundings.

It will +be observed that the black band crossing the centre of the hind +wing is rather broad and sharply bent—an important feature, since +it is the most serviceable distinguishing mark between this species +and the Light Crimson Underwing (<i>C.

It is full fed about the beginning +of June, when it changes to a chrysalis between leaves which it has +spun together with silk.</p> + +<p>The moth flies in July and August, and is common only in +certain oak woods of the southern counties. It is particularly +abundant in the New Forest, where scores may be taken in a +single night by judicious sugaring.</p> + +<p>There yet remain a few small families of the <i>Noctuæ</i>, but we +must leave them in order that we may give a proportionate share +of our space to the other great division of the larger moths—the +<i>Geometræ</i>.<!-- Page 268 --><span class="pagenum"><a name="Page_268" id="Page_268">[Pg 268]</a></span></p> + + + +<hr /> +<h3><a name="CHAPTER_XX" id="CHAPTER_XX"></a>CHAPTER XX +<br /> +<i>GEOMETRÆ</i></h3> + + +<p>We have already referred (page 28) to caterpillars that walk by a +series of strides, alternately looping and extending their long and +slender bodies. It is this peculiar characteristic of the larvæ of +the present division that suggested the name <i>Geometræ</i>—a term +that signifies 'earth-measurers,' for they appear to measure the +ground over which they travel in terms of their own length. We +have also dealt with the peculiarities of structure in the case of +these caterpillars—peculiarities which adapt them to this mode of +progression; and we have now to make a selection from the various +families of this important division for a more detailed description.</p> + +<p>The <i>Geometræ</i> include nearly three hundred species and sixteen +families. The moths have slender bodies and full wings, and +generally rest with the latter outspread. A few, however, repose +with wings erect like the butterflies, and a small number conceal +their hind wings after the manner of the <i>Noctuæ</i>.</p> + + +<h4>Family—<span class="smcap">Uropterygidæ</span> +<br /><br /> +<i>The Swallow Tail</i> (<i>Uropteryx sambucaria</i>)</h4> + +<p>Our first family—<i>Uropterygidæ</i>—has only one British representative, +and that is the well-known Swallow Tail, so common in gardens +and among hedgerows in the south of England. This species +is shown on <a href="#Plate_XII">Plate XII</a> (fig. 2), and the insect is so readily identified +by the conspicuous 'tails' on the hind wings that no written description +will be necessary.</p> + +<p>The caterpillar is a most peculiar and interesting creature. Its +colour is very variable, being either brown, olive, ochreous, or reddish; +and it is notched or humped in such a manner that it exactly +resembles a twig. This strange imitation is rendered still more remarkable<!-- Page 269 --><span class="pagenum"><a name="Page_269" id="Page_269">[Pg 269]</a></span> +by the attitude assumed by the caterpillar when at rest. +It fixes itself to a twig by means of its two pairs of claspers, with +its body standing out at an angle in a perfectly straight posture; +but its head is always supported by means of a very slender and +almost invisible silk fibre. It feeds on a number of plants and trees, +including elder (<i>Sambucus nigra</i>), blackthorn (<i>Prunus spinosa</i>), +whitethorn (<i>Cratægus oxyacantha</i>), bramble (<i>Rubus fruticosus</i>), +honeysuckle (<i>Lonicera Periclymenum</i>), and forget-me-not (<i>Myosotis +arvensis</i>). It may be found feeding in the autumn, or hybernating +in the crevices of the bark of trees in winter. In April or +May it comes out again; and in June, in which month it is full +grown, it binds together some fragments of leaves, and forms +them into a little swinging hammock in which it changes to a brown +chrysalis spotted with black.</p> + +<p>Just at this time it seems to be particularly sensitive. In the +caterpillar state it will strongly resent any kind of disturbance, +and will give a blow to an intruder by suddenly swaying its +body right and left; and while in its hammock a gentle irritation, +such as a puff of wind from the mouth, will set it wriggling in a +furious manner.</p> + + +<h4>Family—<span class="smcap">Ennomidæ</span></h4> + +<p>This family contains about twenty species, several of which rank +among the commonest as well as the most beautiful of the <i>Geometræ</i>. +Their wings are more or less angulated; and the antennæ +are generally pectinated in the males.</p> + +<p>The larvæ are generally humped and twig-like; and, as in the +last species, the semblance is increased by the position they assume +when at rest. The number of limbs varies from ten to fourteen, but +where the claspers exceed two pairs, the additional two or four, as +the case may be, are seldom used in walking.</p> + + +<h4><i>The Brimstone Moth</i> (<i>Rumia luteolata</i>)</h4> + +<p>As soon as the warm evenings of May set in, this lively and +bright little moth may be seen flitting about among our hedges at +sunset; and it continues with us throughout the whole of the summer, +but is particularly plentiful during the month of June.</p> + +<p>The moth itself need not be described, since it is shown on <a href="#Plate_XII">Plate +XII</a> (fig. 3); but the caterpillar (<a href="#FIG_25">fig. 25</a>) must receive a passing +notice. It varies considerably in colour, being either green, brown,<!-- Page 270 --><span class="pagenum"><a name="Page_270" id="Page_270">[Pg 270]</a></span> +or marbled with a mixture of shades of both these colours. It has +a hump on the back of the seventh segment, and two more on the +ninth, and possesses four pairs of claspers. It feeds on whitethorn +(<i>Cratægus oxyacantha</i>), blackthorn (<i>Prunus spinosa</i>), and the +apple (<i>Pyrus Malus</i>), and may be found on these trees throughout +the summer.</p> + +<p>Some believe that there are three successive broods of this insect +each year, but it is doubtful whether this is invariably the rule, since +both the moth and its larva are to be found without intermission +throughout the season.</p> + + +<h4><i>The Light Emerald</i> (<i>Metrocampa margaritaria</i>)</h4> + +<div class="figright" style="width: 300px;"> +<a name="FIG_177" id="FIG_177"></a><a href="images/i_287.jpg"><img src="images/i_287_tn.jpg" width="300" height="99" alt="" title="Linked to larger image of The Light Emerald." /></a> +<span class="caption">Fig. 177.—The Light Emerald.</span> +</div> + +<p>All the wings of this moth are very pale green, and crossed with +a white band which is bordered with a darker green on the inner +side.

There is a yellow band on the front of +the second segment, a row of yellow spots on each side, and two +little bright yellow warts on the back of each segment. It feeds by +night on lime (<i>Tilia vulgaris</i>), elm (<i>Ulmus campestris</i>), and +various fruit trees, and often appears in such numbers that the +foliage is almost completely devoured. During the daytime it may +be seen resting on the bark, almost invariably fixed longitudinally +on the trunk, where it looks like a natural ridge of the bark which +it so closely resembles in colour. It may be found in June and +July, and in August it changes to a chrysalis at the foot of its tree, +just below the surface of the soil.</p> + + +<h4><i>The Peppered Moth</i> (<i>Amphidasys betularia</i>)</h4> + +<div class="figright" style="width: 300px;"> +<a name="FIG_179" id="FIG_179"></a><a href="images/i_289.jpg"><img src="images/i_289_tn.jpg" width="300" height="101" alt="" title="Linked to larger image of The Peppered Moth." /></a> +<span class="caption">Fig. 179.—The Peppered Moth.</span> +</div> + +<p>Although this common species displays no bright tints, yet it is +prettily marked, its whitish wings being peppered and blotched all +over with black or very dark brown.

These latter are only small reddish or whitish +projections, of which there is one on each side of the fifth, sixth, +seventh, eighth, tenth, and eleventh segments; also two on the +back of the ninth and twelfth. It feeds in August and September +on a large number of trees, including, in fact, nearly all our commonest +forest and fruit trees. In September it enters the soil to +undergo its change to the chrysalis.</p> + + +<h4>Family—<span class="smcap">Boarmiidæ</span></h4> + +<p>In the next family—<i>Boarmiidæ</i>—there are about twenty British +members, most of which are very pretty moths. They differ +generally from the last family in that their bodies are more slender,<!-- Page 273 --><span class="pagenum"><a name="Page_273" id="Page_273">[Pg 273]</a></span> +and although some of them bear a resemblance to species of the +family <i>Ennomidæ</i>, their wings are not angulated.

Most of the +larvæ are leaf miners, +and are easily reared. +All that is necessary is +to pluck a few twigs, +the leaves of which, +when held up to the +light, reveal the tiny +larvæ in their burrows, +and place them in a vessel of water. They do not feed long, and +it is probable that most of the larvæ so treated will be ready to +change before the leaves have become dry. The present species +has bright yellow fore wings, with pale grey cloudings at the hind +margins. It is very abundant in many parts, and flies during the +month of June.</p> + +<p>The larva is one of the numerous leaf miners, and is of a +yellowish colour.

+<i>THE LEPIDOPTERIST'S CALENDAR</i></h3> + +<p>The success of the country rambles of an expert lepidopterist depends +greatly on his knowledge of the times at which the various +butterflies and moths generally appear, and of the localities which +they are known to frequent. The experiences he has gained in the +past enable him to calculate on the probabilities of the future, and +he chooses both time and locality according to his requirements.</p> + +<p>As he makes his way to the hunting ground he counts over the +chances of meeting with a certain insect that is wanted to fill a +long-standing blank in his cabinet; and we hear him discussing the +probabilities as to whether this species is yet 'out,' or whether the +larvæ of that species are feeding.</p> + +<p>How different it is with the young and unguided entomologist! +He rambles promiscuously here and there, having only the faintest +idea as to what he is likely to see, and perhaps meeting with only +four or five species when an experienced collector, without covering +a larger area of ground, would take scores in the same time.</p> + +<p>In order to afford some little help to the beginner, I have +thought it advisable to introduce a calendar of operations to guide +him in his work. The space at our command would not allow this +to be carried out in detail, but the general instructions will undoubtedly +assist most of my readers until the practical experience +gained by a few years' work has enabled them to run on their own legs.<!-- Page 327 --><span class="pagenum"><a name="Page_327" id="Page_327">[Pg 327]</a></span></p> + +<p>Of course, in making reference to the monthly lists of insects on +the wing, allowance must be made for the forwardness or backwardness +of the seasons. Thus, an insect entered in the April list <i>may</i> +appear in March in an exceptionally warm season, but may not +emerge till the early part of May if the spring has been unusually +severe.</p> + +<p>It will be observed that in cases where all the species of a +certain genus or family appear on the wing in the same month, the +name of that genus or family is entered on the list instead of the +names of the individual species; but the latter can easily be obtained +by reference to <a href="#APPENDIX_I">Appendix I</a>.</p> + + +<h4>JANUARY</h4> + +<p>There is not much field work to be done during this month. If +the weather is very severe, hardly an insect will be found on the +wing; but a mild January will sometimes entice the Brimstone +Butterfly (<i>Rhamni</i>) and some of the hybernating Vanessas from +their winter quarters.</p> + +<p>Hybernating moths may also be met with, on the wing if the +weather is mild, or sleeping in their sheltered nooks during the +frosts. These include several <i>Noctuæ</i>—<i>Auricoma</i>, <i>Lithargyria</i>, +<i>Suffusa</i>, <i>Vaccinii</i>, <i>Spadicea</i>, <i>Erythrocephala</i>, <i>Satellitia</i>, <i>Rubiginea</i>, +<i>Croceago</i>, <i>Vetusta</i>, <i>Exoleta</i>, <i>Ornithopus</i>, <i>Furcifera</i>, <i>Semibrunnea</i>, +<i>Socia</i>, and <i>Libatrix</i>; and also a few <i>Geometræ</i>—<i>Zonaria</i>, +<i>Fluviata</i>, <i>Dubitata</i>, <i>Siterata</i>, and <i>Miata</i>.</p> + +<p>In addition to these hybernating insects, the collector may +examine tree trunks and fences for the Early Moth (<i>Rupicapraria</i>), +and late specimens of the Winter Moth (<i>Brumata</i>); and towards the +end of the month he may expect to meet with fresh specimens of +the Pale Brindled Beauty (<i>Pedaria</i>) and the Spring Usher (<i>Leucophæaria</i>). +A few of the <i>Tineæ</i> may also be seen.</p> + +<p>The net need not be used at all during the colder months of the +year, as the moths are easily taken in pill boxes from the trunks +and fences on which they rest.</p> + +<p>Pupa digging may be carried on throughout the month if the +weather is sufficiently mild, but it is of no use attempting this +during a frost. Hybernating larvæ may also be searched out of +their winter quarters if the collector does not mind giving them the +attention they require; but, as a rule, it is better to wait till they +themselves start out to feed in the spring, at which time all their +food plants are showing leaf.</p> + + +<h4>FEBRUARY</h4> + +<p>Our remarks under 'January' concerning pupa digging and +other work apply equally well to this month. The same hybernating +butterflies and moths may be looked for; and, in addition to<!-- Page 328 --><span class="pagenum"><a name="Page_328" id="Page_328">[Pg 328]</a></span> +<i>Pedaria</i>, <i>Leucophæaria</i>, and <i>Rupicapraria</i>, which now appear +more plentifully, the following species will probably be seen:</p> + +<ul> +<li>Small Eggar (<i>Lanestris</i>)</li> +<li>Small Brindled Beauty (<i>Hispidaria</i>)</li> +<li>Oak Beauty (<i>Strataria</i>)</li> +<li>Dotted Border (<i>Marginaria</i>)</li> +<li>March Moth (<i>Æscularia</i>)</li> +</ul> + +<p>About half a dozen species of the <i>Tineæ</i> will also have made +their appearance before the end of the month.</p> + + +<h4>MARCH</h4> + +<p>Many of the hybernating larvæ will come out during March if +the weather is mild, and commence to feed; and the young caterpillars +will begin to appear from the eggs of the early moths already +named. This is consequently a good time to commence the search +for larvæ if you intend to go in for rearing. During the daytime +some may be beaten from the boughs of trees and shrubs; and those +which feed on low plants, being generally nocturnal in their habits, +should be searched for in the evening, after dark, with the aid of a +lantern.</p> + +<p>The hybernating butterflies are now flying more freely than +before, and, if the weather is bright and warm for the time of year, +a few freshly emerged species may be seen. These may possibly +include:</p> + +<ul> +<li>Large White (<i>Brassicæ</i>)</li> +<li>Small White (<i>Rapæ</i>)</li> +<li>Green-veined White (<i>Napi</i>)</li> +<li>Holly Blue (<i>Argiolus</i>)</li> +</ul> + +<p>As regards moths, several fresh species may be expected to +appear, while those named as appearing in February are still to be +found.

The cyanide bottle should be freshly charged, nets examined +and repaired if necessary, and all setting boards, breeding cages +&c. put in perfect trim for the new season's work.</p> + +<p>Larvæ are now feeding freely, and a few hours spent in beating, +sweeping, and searching will enable you to stock your cages +liberally.</p> + +<p>Sugaring may be continued throughout the month, and the +sallow

The early butterflies are disappearing, or perhaps have +quite left us; but new species are taking their place. The +<i>Sphinges</i> now reach their maximum, as do also the <i>Bombyces</i>; and +the other groups are almost if not quite up to their highest total. +The <i>Noctuæ</i> and <i>Geometræ</i> each amount to over a hundred species. +No less than a hundred and fifty British <i>Tortrices</i> are on the wing; +the <i>Tineæ</i> make a near approach to three hundred, and the <i>Pyralides</i> +of the month are not far short of numbering a hundred species. +It will thus be seen that the net and pill boxes, as well as the setting +boards, are in constant demand.</p> + +<p>Dull days may be well occupied in beating for moths, and in the +examination of fences and the bark of trees; and on bright days, +as soon as the butterflies have settled down to rest, the same work +may be carried on till dusk.</p> + +<p>Micros and <i>Geometræ</i> are out early in the evening, when they +should be taken with the net. Later on the <i>Noctuæ</i> may be seen +playing round their favourite flowers.</p> + +<p>Sugar and light traps are likely to do good service during June, +and decoy females of the <i>Bombyces</i> group may be called to your +aid.</p> + +<p>Larvæ are also abundant during June, and those of most of the +butterflies may be taken by carefully searching their food plants.</p> + +<p>The following is

Clover and lucerne fields should be well worked.</p> + +<p>A few <i>Sphinges</i> and a number of the <i>Bombyces</i> are still on the +wing. The <i>Noctuæ</i> are on the decrease, but there are yet nearly +a hundred species (including the rarer ones) at large.<!-- Page 339 --><span class="pagenum"><a name="Page_339" id="Page_339">[Pg 339]</a></span></p> + +<p>These last may be taken at sugar in considerable numbers, and +it is interesting to note that two of the Vanessas (<i>Atalanta</i> and +<i>Cardui</i>) may be caught sipping on your baited trees during the +daytime.</p> + +<p><i>Geometræ</i> and Micros fall off very considerably this month, but +these, as well as moths of the other groups, may be taken from +tree trunks and palings. Light traps may also be used with much +success during August.</p> + +<p>Fallen fruits should be examined for the larvæ that feed within +them; and late in the month ripe fruit will supply food to the +lovers of sweets.</p> + +<p>Ivy blossom should be well worked at night; and clover and +lucerne fields form admirable hunting grounds for moths at night, +especially just after rain.</p> + +<p>Larvæ

Project Gutenberg volunteers and employees expend considerable +effort to identify, do copyright research on, transcribe and proofread +public domain works in creating the Project Gutenberg-tm +collection. Despite these efforts, Project Gutenberg-tm electronic +works, and the medium on which they may be stored, may contain +"Defects," such as, but not limited to, incomplete, inaccurate or +corrupt data, transcription errors, a copyright or other intellectual +property infringement, a defective or damaged disk or other medium, a +computer virus, or computer codes that damage or cannot be read by +your equipment. + +1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right +of Replacement or Refund" described in paragraph 1.F.3, the Project +Gutenberg Literary Archive Foundation, the owner of the Project +Gutenberg-tm trademark, and any other party distributing a Project +Gutenberg-tm electronic work under this agreement, disclaim all +liability to you for damages, costs and expenses, including legal +fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT +LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE +PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE +TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE +LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR +INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH +DAMAGE. + +1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a +defect in this electronic work within 90 days of receiving it, you can +receive a refund of the money (if any) you paid for it by sending a +written explanation to the person you received the work from. If you +received the work on a physical medium, you must return the medium with +your written explanation. The person or entity that provided you with +the defective work may elect to provide a replacement copy in lieu of a +refund. If you received the work electronically, the person or entity +providing it to you may choose to give you a second opportunity to +receive the work electronically in lieu of a refund. If the second copy +is also defective, you may demand a refund in writing without further +opportunities to fix the problem. + +1.F.4. Except for the limited right of replacement or refund set forth +in paragraph 1.F.3, this work is provided to you 'AS-IS,' WITH NO OTHER +WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO +WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE. + +1.F.5. Some states do not allow disclaimers of certain implied +warranties or the exclusion or limitation of certain types of damages. +If any disclaimer or limitation set forth in this agreement violates the +law of the state applicable to this agreement, the agreement shall be +interpreted to make the maximum disclaimer or limitation permitted by +the applicable state law. The invalidity or unenforceability of any +provision of this agreement shall not void the remaining provisions. + +1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the +trademark owner, any agent or employee of the Foundation, anyone +providing copies of Project Gutenberg-tm electronic works in accordance +with this agreement, and any volunteers associated with the production, +promotion and distribution of Project Gutenberg-tm electronic works, +harmless from all liability, costs and expenses, including legal fees, +that arise directly or indirectly from any of the following which you do +or cause to occur: (a) distribution of this or any Project Gutenberg-tm +work, (b) alteration, modification, or additions or deletions to any +Project Gutenberg-tm work, and (c) any Defect you cause. + + +Section 2. Information about the Mission of Project Gutenberg-tm + +Project Gutenberg-tm is synonymous with the free distribution of +electronic works in formats readable by the widest variety of computers +including obsolete, old, middle-aged and new computers. It exists +because of the efforts of hundreds of volunteers and donations from +people in all walks of life. + +Volunteers and financial support to provide volunteers with the +assistance they need are critical to reaching Project Gutenberg-tm's +goals and ensuring that the Project Gutenberg-tm collection will +remain freely available for generations to come. In 2001, the Project +Gutenberg Literary Archive Foundation was created to provide a secure +and permanent future for Project Gutenberg-tm and future generations. +To learn more about the Project Gutenberg Literary Archive Foundation +and how your efforts and donations can help, see Sections 3 and 4 +and the Foundation web page at http://www.gutenberg.org/fundraising/pglaf. + + +Section 3. Information about the Project Gutenberg Literary Archive +Foundation + +The Project Gutenberg Literary Archive Foundation is a non profit +501(c)(3) educational corporation organized under the laws of the +state of Mississippi and granted tax exempt status by the Internal +Revenue Service. The Foundation's EIN or federal tax identification +number is 64-6221541. Contributions to the Project Gutenberg +Literary Archive Foundation are tax deductible to the full extent +permitted by U.S. federal laws and your state's laws. + +The Foundation's principal office is located at 4557 Melan Dr. S. +Fairbanks, AK, 99712., but its volunteers and employees are scattered +throughout numerous locations. Its business office is located at +809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887, email +business@pglaf.org. Email contact links and up to date contact +information can be found at the Foundation's web site and official +page at http://www.gutenberg.org/about/contact + +For additional contact information: + Dr. Gregory B. Newby + Chief Executive and Director + gbnewby@pglaf.org + +Section 4. Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://www.gutenberg.org/fundraising/pglaf + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses. Donations are accepted in a number of other +ways including checks, online payments and credit card donations. +To donate, please visit: http://www.gutenberg.org/fundraising/donate + + +Section 5. General Information About Project Gutenberg-tm electronic +works. + +Professor Michael S. Hart is the originator of the Project Gutenberg-tm +concept of a library of electronic works that could be freely shared +with anyone. For thirty years, he produced and distributed Project +Gutenberg-tm eBooks with only a loose network of volunteer support. + +Project Gutenberg-tm eBooks are often created from several printed +editions, all of which are confirmed as Public Domain in the U.S. +unless a copyright notice is included. Thus, we do not necessarily +keep eBooks in compliance with any particular paper edition. + +Each eBook is in a subdirectory of the same number as the eBook's +eBook number, often in several formats including plain vanilla ASCII, +compressed (zipped), HTML and others. + +Corrected EDITIONS of our eBooks replace the old file and take over +the old filename and etext number. The replaced older file is renamed. +VERSIONS based on separate sources are treated as new eBooks receiving +new filenames and etext numbers. + +Most people start at our Web site which has the main PG search facility: + +<a href="http://www.gutenberg.org">http://www.gutenberg.org</a> + +This Web site includes information about Project Gutenberg-tm, +including how to make donations to the Project Gutenberg Literary +Archive Foundation, how to help produce our new eBooks, and how to +subscribe to our email newsletter to hear about new eBooks. + +EBooks posted prior to November 2003, with eBook numbers BELOW #10000, +are filed in directories based on their release date. If you want to +download any of these eBooks directly, rather than using the regular +search system you may utilize the following addresses and just +download by the etext year. + +<a href="http://www.gutenberg.org/dirs/etext06/">http://www.gutenberg.org/dirs/etext06/</a> + + (Or /etext 05, 04, 03, 02, 01, 00, 99, + 98, 97, 96, 95, 94, 93, 92, 92, 91 or 90) + +EBooks posted since November 2003, with etext numbers OVER #10000, are +filed in a different way. The year of a release date is no longer part +of the directory path. The path is based on the etext number (which is +identical to the filename). The path to the file is made up of single +digits corresponding to all but the last digit in the filename. For +example an eBook of filename 10234 would be found at: + +http://www.gutenberg.org/dirs/1/0/2/3/10234 + +or filename 24689 would be found at: +http://www.gutenberg.org/dirs/2/4/6/8/24689 + +An

Necessarily each subject was only briefly +touched upon, but the study is of so enticing a character that 'appetite +grows by feeding,' and the students of the 'Out-door World,' having +tasted the sweetness of companionship with Nature, will not rest +satisfied with the help afforded by that handbook. Each one will want to +go deeper into that particular department which most appeals to his own +inclinations. + +The present volume is written expressly for those who desire to extend +their knowledge of the British Lepidoptera, or, to use the more popular +names, 'Butterflies and Moths.' + +The general characteristics of this interesting order of insects are +described somewhat fully, but, of course, it would be impossible to give +an individual account of all the British Lepidoptera in a work of this +size, so a selection has been made such as will satisfy the requirements +of the great majority of those who intend to take up this particular +branch of entomology. The number of British Butterflies, however, is +so limited that a place has been found for a figure and a description of +every species; and, of the larger moths, many of the common and typical +kinds have been included. An introduction to the study of the +Micro-lepidoptera has also been added. + +No trouble has been spared to render this work thoroughly practical. In +addition to the verbal descriptions of so many species, twelve coloured +plates and a large number of woodcuts have been specially prepared to +help the student in his work. It is believed that the extreme care with +which these have been produced will render them of the greatest +assistance to the collector in the recognition of his specimens. + +But he has not only to recognise his specimens--he must first catch +them; and here full directions have been given to insure success in this +part of his work, as well as in the management, preservation, and +arrangement of his captures. + +The Author hopes that this volume may be the means of adding many happy +hours--hours of the purest enjoyment--to the lives of those whom he has +succeeded in luring into the fields and lanes and woods of the Out-door +World. + + +CONTENTS + + PART I + + _STRUCTURE AND LIFE HISTORY OF THE LEPIDOPTERA_ + + CHAP.

AURELLA--ENLARGED 307 + + + + +PART I + +STRUCTURE AND LIFE-HISTORY OF THE LEPIDOPTERA + +CHAPTER I + +_GENERAL CHARACTERS_ + + +The word _Lepidoptera_, which you see at the head of this page, is the +name of the order of insects to which this volume is to be devoted. It +is formed from two Greek words, one (_lepis_) signifying a _scale_, and +the other (_pteron_) denoting a _wing_; and was applied by the great +naturalist Linnaeus to the scaly-winged insects popularly known as +Butterflies and Moths. + +[Illustration: FIG. 1.--SCALES FROM THE WINGS OF BUTTERFLIES.] + +Every one of my readers has undoubtedly handled some of the interesting +creatures of this group--having been led to do so either by the extreme +beauty of their clothing, or, perhaps, from a murderous intent in order +to protect his own garments from the ravages of a supposed marauder. A +light mealy powder will probably have been observed afterwards on the +fingers that have touched the victim's wings. + +This powder, although it sometimes presents a beautiful glossy surface +when spread over the skin, does not exhibit any definite form or +structure without a more minute examination. Yet these are the scales +that led the immortal naturalist to invent the somewhat long but useful +term _Lepidoptera_. + +The very next time the opportunity offers itself, dust off a little of +the mealy powder with a small and very soft brush on to a strip of white +paper or a slip of glass, and examine it with a powerful lens or the low +power of a compound microscope. What a sight you will then behold! Each +little particle of dust is a beautifully formed scale, stamped with a +number of minute rounded projections, and often displaying the most +gorgeous colours. A great variety of designs and tints are often +exhibited by the 'dust' from a single wing. Take, for instance, for your +inspection, scales from the wing of one of our commonest insects, the +Small Tortoiseshell Butterfly (Plate III), and you will be surprised at +the pleasing contrasts. But when your curiosity leads you to deal with +others in the same manner, the varied display of forms and colours is +simply amazing. + +[Illustration: FIG. 2.--PORTION OF THE WING OF A BUTTERFLY FROM WHICH +SOME OF THE SCALES HAVE BEEN REMOVED.] + +In order that we may learn still more of the structure of the wings of +the _Lepidoptera_, we will examine a portion of one from which some of +the scales have been removed, again bringing the lens or the microscope +into our service. We now see that the scales are arranged in rows with +great regularity on a thin and transparent membrane, which is supported +by a system of branching rays. And the membrane itself, in parts which +have been laid bare, is marked with regular rows of dots--the points at +which the scales were originally attached by means of short hollow rods. + +The framework that supports the thin membrane we have spoken of as +consisting of a system of _rays_, but to these the terms _veins_, +_nerves_, _nervures_, or _nervules_ are more commonly applied by various +naturalists. We cannot do better, however, than adhere to the name +originally used, for the structures in question do not perform the +functions of veins, though at first they contain blood, nor are they +themselves parts of the nervous systems of the insects to which they +belong. + +The result of our examination of the wings of butterflies and moths has +been to justify the application of the term _Lepidoptera_; but we must +now study other equally important and interesting features of the +structure of these insects. First, let us note the general form of the +body. + +[Illustration: FIG. 3.--BODY OF A BUTTERFLY--UNDER SIDE. + +1-7, segments of the abdomen; 8, anal extremity; _a_, antennae; _b_, +tarsus; _c_, tibia; _d_, femur; _e_, palpi; _f_, head; _g_, thorax.] + +A cursory glance at this portion of the creature's anatomy will show +that it consists of three distinct and well-defined parts. In front +there is the head, the size of which is somewhat small in proportion. +Two very large eyes make up the greater portion of its bulk. It is +remarkable, too, that butterflies possess eyes proportionately much +larger than those of moths. Now, since butterflies always fly by day, +and moths are, generally speaking, nocturnal insects, we might be led to +suppose that the reverse of this arrangement would have suited the +creatures better; for a small eye, we should think, would be able to +collect sufficient light in the daytime to form a bright image, and a +larger light-receiving area would be necessary during the darker hours +for the same purpose. But it is evident that the sense of vision must +depend on other conditions besides the size of the eye; and as these +conditions are not understood in relation to the eyes of insects, any +attempt at an explanation would be quite useless. + +The eye of a butterfly or moth is worthy of a closer examination, for it +is a most beautiful and marvellous structure. The outer globular +transparent membrane--the _cornea_--is divided into a large number of +minute polygonal _facets_, each one of which admits light into a small +conical compartment surrounded by a coloured membrane, and supplied with +a fibre of the nerve of vision (the _optic_ nerve). Hence the eye is +often spoken of as _compound_. + +If you look closely into the eyes of various butterflies and moths you +will generally see a ground colour of grey, blue, brown, or black; but +when viewed at certain angles in a strong light the most gorgeous hues +of metallic brilliancy--gold, copper, and bronze--are to be observed. +All such colours are due to the reflection of light from the colouring +matter that lies between the numerous conical compartments. + +[Illustration: FIG. 4.--SECTION OF THE EYE OF AN INSECT.] + +A glance at the section of a compound eye will show you that all the +little cones radiate from a common centre. And, as each little +compartment is surrounded by opaque colouring matter, it is clear that +perpendicular rays only are capable of penetrating to its base and +exciting the nerve fibre that lies there. Thus each little division of a +compound eye forms its own image of the object that happens to be +exactly opposite its facet. But how many facets do we find in a single +eye? Sometimes only a few hundreds, but sometimes as many as seventeen +or eighteen thousand! We must not, however, conclude that the nature of +the vision of butterflies and moths is necessarily very different from +our own. We have two eyes, but the images formed by them are both +blended, so that we do not see double. We can understand, therefore, +that the thousands of images formed in a single eye may be blended +together so as to form one continuous picture. Still there remains this +difference: while in our own case the two images formed by the two eyes +are practically the same, in the case of insects every one of the little +conical tubes of a compound eye forms an image of an object that cannot +possibly be formed by any one of the others. Thus, if the lepidopterous +insect sees a continuous picture of its surroundings, such a picture is +produced by the overlapping and blending, at their edges, of hundreds or +thousands of distinct parts. + +There is yet another interesting difference between the vision of these +insects and that of ourselves. As already stated, our two eyes are both +turned toward the same point at the same time. But look at the +butterfly's eyes. Here are no movable eyeballs, and the two eyes, placed +as they are at the _sides_ of the head, are always turned in _opposite_ +directions. The corneae, too, are very convex; and consequently the range +of vision is vastly wider than ours. A boy is often easily surprised by +a playmate who approaches him stealthily from behind, but did you ever +try the same game with a butterfly? I have, many a time. After getting +cautiously so near to a butterfly at rest as to be able to distinguish +between its head and its hinder extremity, I have quietly circled round +it so as to approach it from behind, being at the time under the +impression that it wouldn't see me under those circumstances. But not +the slightest advantage did I derive from this stratagem, for the +position and construction of its eyes enabled it to see almost all ways +at once. + +In addition to the two compound eyes, the _Lepidoptera_, or at least +most of them, are provided with two small simple eyes; but these are +generally so hidden among the closely set hair that covers the head, +that it is doubtful whether they are of much service as organs of +vision. + +[Illustration: FIG. 5.--ANTENNAE OF BUTTERFLIES.] + +[Illustration: FIG. 6.--ANTENNAE OF MOTHS.] + +The antennae proceed from two points close to the upper borders of the +eyes. They are jointed organs, and are of very different forms in the +various species of _Lepidoptera_. They are generally long, slender, and +clubbed at the extremity in butterflies, but exhibit several minor +points of difference which we shall have to note later on. In moths the +antennae are sometimes long, slender, and pointed. Some are thick, and +more or less prismatic in form; while others are slightly or deeply +pectinated or comb-like. The antennae of butterflies are always +straight, or only slightly curved; and, although the insects can sway +them bodily, they have no power to bend them, or to stow them away in +any place of shelter. Moths, on the other hand, when at rest, are almost +invariably found to have their antennae snugly tucked under the wings, +and brought so closely against the side of the head for this purpose +that even the uncovered portion is often difficult to find. + +There are two other prominent appendages belonging to the heads of the +_Lepidoptera_. These are the _labial palpi_ or feelers of the lips. They +are generally easily seen, projecting forward on the under side of the +head, sometimes so long and conspicuous as to give one the idea of a +snout or long nose. The palpi are jointed--usually in three parts--are +covered with scales, and often furnished with hairs or bristles. + +If you watch a moth or butterfly when it is feeding on the sweet juices +of a flower, or on some kind of artificial sweet with which you have +provided it, you will observe its long trunk or _proboscis_, by which +food is sucked up. This instrument is so long and slender that it seems +almost impossible that it can be a tube through which a liquid freely +passes. But a careful examination will show that this is the case. It is +composed of two separate pieces--two half tubes, which, when closely +applied to each other, form a very thin and flexible pipe, perfectly +air-tight and adapted for suction. Sometimes you can see a butterfly or +moth manipulating with its proboscis as if it required readjustment in +some way or other. It has split the tube throughout its length, so that +it now looks like two exceedingly fine hairs. Then, after a short time, +the two halves are put together again, and immediately, as if by magic, +become a single tube in which no kind of seam is to be observed without +a powerful magnifier. + +In order to observe the nature of such a wonderful arrangement we must +have recourse to the aid of a good microscope. Thus assisted, we can see +at once how the junction of the two sides of the proboscis is brought +about so quickly and so perfectly. The inner edges of each half are very +regularly fringed with lines of closely set hairs--so regular, in fact, +are they, that they give one the idea of long yet minute beautifully +formed combs. When the two parts are brought together, the hairs of two +opposite edges interlock, those on one side exactly filling the spaces +between those of the other. + +The microscope also reveals another interesting fact, viz. that the +proboscis is not a single tube, but, although so remarkably thin, is +really a set of three distinct pipes, one lying on each side of the +central one. It is said that the central tube only is used for sucking +up the liquid food, and there seems to be some doubt as to the uses of +the other two. Some naturalists are of opinion that the latter are air +tubes, and are connected with the respiration of the insect; while +others say that through these the insects eject a thin watery fluid with +which to dissolve or dilute those sweetmeats that are not sufficiently +liquid to be readily sucked up. But possibly both these opinions are +correct, the proboscis serving all three of the purposes here named. The +only observation of my own bearing on the subject is this. While a moth +was feeding on a drop of syrup in a strong light, a powerful lens +revealed drops, of liquid, mingled with bubbles of air, passing +alternately _up and down_ the two lateral tubes of the proboscis. At the +same time the upward current of syrup in the central tube was by no +means steady and continuous. + +[Illustration: FIG. 7.--SECTION OF THE PROBOSCIS OF A BUTTERFLY.] + +When this organ is not in use, it is beautifully coiled into a close +spiral which lies between the labial palpi. The length varies +considerably in different insects, and consequently the number of turns +in the spiral must differ also. Sometimes there are less than two turns, +while some of the longer ones form spirals of from six to ten turns. + +In concluding our brief account of the head of lepidopterous insects it +is, I suppose, hardly necessary to add that there is no kind of chewing +apparatus to be described; all the members of this order, at least in +the perfect state, deriving the whole of the little nourishment they +require entirely by suction through the proboscis or 'trunk.' + +The second division of the body is the _thorax_. This is much larger +than the head, and consists of three ring-like segments, joined one +behind the other so intimately that the lines of junction are hardly +visible, even after the thick clothing of fine hair has been brushed +off. Behind the thorax is the abdomen, which is composed of several +segments, the junctions between the rings often being most distinct. + +From the sides of the thorax proceed the two pairs of wings, the general +structure of which we have already to a certain extent examined. But +when we are a little farther advanced in our insect studies, we shall +have to become acquainted with detailed descriptions given as aids to +the identification of species. Now, such descriptions cannot be +satisfactory, either to the one who gives or to him who receives, unless +expressed in such definite terms as render a misunderstanding +impossible. A botanist cannot give an accurate and concise description +of a flower without the use of certain names and expressions which have +gradually become an almost necessary part of his vocabulary; neither can +an entomologist give a really useful, and, at the same time, a +_succinct_ description of an insect unless he is acquainted with the +names of its parts. Therefore, seeing that we distinguish the various +species of butterflies and moths _mainly_ by the arrangement and colour +of the markings of their wings, it is really necessary that we should +know the names of the different parts of these organs. For this reason I +have inserted drawings of a fore and of a hind wing of a butterfly, +together with the names of the various parts of the wings, and also the +names of the principal rays or _nervures_. Yet I would not advise any +young entomologist to attempt to commit to memory all the names given. +Rather use the diagram for reference when occasion requires, more +particularly when you have an insect in your possession that you desire +to study. In ordinary descriptions of butterflies and moths the names of +the _nervures_ are not so generally used as those of the _parts_ of the +wing. Consequently it is exceedingly useful to know what is meant by the +terms _base_, _costal margin_, _apex_, _hind margin_, _anal angle_, +_inner margin_, _discoidal cell_ &c. as applied to the wing. + +The two pairs of wings are attached to the second and third segments of +the thorax; but of the _three_ pairs of legs, which we have next to +consider, one pair arises from each of the three segments. The +arrangement of these limbs is well shown in the sketch on page 3, as are +also the names of the different parts of the limb, the latter being +given for reference by the reader when the need arises. + +All insects, in their perfect state, we are told, have three pairs of +legs; but if you examine the under surface of certain butterflies, such +as the Marbled White, or any of the Vanessas, Browns, or Heaths, it is +quite likely that you will raise objection to such a statement; for in +these you may possibly see only four legs. But this is the result of a +too cursory observation. Look a little more closely at your specimen, +and you will see a pair of smaller legs folded up under the fore part of +the thorax. By means of a blunt needle you can straighten out these +limbs, and then the difference in length to be observed between them and +the other four is very striking indeed. They are also thinner than the +middle and hind legs; and, unlike these, are not provided with claws. + +[Illustration: FIG. 8.--DIAGRAM OF THE WINGS OF A BUTTERFLY. + +I. _Fore wing._--1-5, subcostal nervules; 6, 7, discoidal nervules; +8-10, median nervules; 11, submedian nervure; 12, internal nervure; +13-15, disco-cellular nervules; 16, interno-median nervule; 17, median +nervure; 18, subcostal nervure; _a_, costal nervure; _b_, costa or +anterior margin; _c_, apex or anterior angle; _d_, posterior or hind +margin; _e_, posterior or anal angle; _f_, interior or inner margin; +_g_, base; _h_, discoidal cell. + +II. _Hind wing._--1, 2, subcostal nervules; 3, discoidal nervule; 4-6, +median nervules; 7, submedian nervure; 8, precostal nervure; 9, +subcostal nervure; 10, median nervure; 11, 12, disco-cellular nervules; +_a_, costal nervure; _b_, costa or anterior margin; _c_, apex or +anterior angle; _d_, hind margin; _e_, tail or caudal appendage; _f_, +anal angle; _g_, abdominal or inner margin; _h_, base.] + +These imperfectly developed legs are, of course, quite useless as far as +walking is concerned; indeed, it is extremely doubtful as to whether +they are of any service whatever to the owner. On one occasion, +however, while watching a Peacock Butterfly apparently engaged in +cleaning its divided proboscis, I observed that this organ was +frequently passed under the thorax, and that the front pair of legs were +pressed against it on each side, while it was being drawn outward +between them. It is probable, therefore, that these limbs constitute a +pair of brushes by means of which the fine grooves of the divided trunk +are cleared of any solid or sticky matter that may lodge therein. It is +certain that moths, and those butterflies that possess six _equal_ legs, +use the front pair for this same purpose. The former, also, employ them +for brushing their antennae, which seem to be, by the way, particularly +sensitive to different kinds of irritation. + +[Illustration: FIG. 9.--THE UNDEVELOPED FORE LEG OF A BUTTERFLY.] + +It is a well-known fact that tobacco smoke has a powerful influence on +certain small insects; and even though it can hardly be regarded as a +perfect all-round insecticide, it is certainly more or less +objectionable to the larger and hardier species. A short time since, +while watching a number of newly emerged moths of the _Sphinx_ group, +and at the same time enjoying the solace afforded by the luxurious weed, +a puff of the smoke was accidentally allowed to play into the box in +which my pets were for the time imprisoned. Immediately they rubbed +their front legs vigorously over the antennae, as if to remove the +obnoxious irritant that had thus intruded on their presence. Similar +observations have led many naturalists to suppose that the antennae are +the seat of various senses, such as those of touch, hearing, and smell. +Seeing that insects do not, as far as we know, possess special organs +for all the five senses which we enjoy (and it is interesting to note +here that some insects certainly experience other sensations which are +quite beyond our ken), we can quite understand the common tendency to +locate the seats of certain of the senses in such easily affected parts +as the antennae. But little, I believe, has been definitely proved save +that the antennae are sensitive to touch and to irritants generally. + +While speaking of the senses of insects, I cannot refrain from +mentioning a most remarkable example of a peculiar sensitiveness that +has been observed in certain moths of the family _Bombyces_ (page +217)--notably the Oak Eggar, the Emperor, and the Kentish Glory. Take a +newly emerged female of either of these species, shut her up in a small +box, conceal the box in your pocket, and then walk about in some +country spot known to you as being one of the haunts of that species of +moth. Then, if any of the males of the same species happen to be in the +neighbourhood, they will settle or hover about close to the female +which, although still concealed and quite out of their reach, has +attracted them to the spot. + +What a marvellously acute sense this must be, that thus enables the +insects to scent out, as it were, their mates at considerable distances, +even when doubly surrounded by a wooden box and the material of a coat +pocket! You would naturally expect that entomologists have turned this +wonderful power to account. Many a box has been filled with the +beautiful Kentish Glories of the male kind, who had been led into the +snare by the attractions of a virgin Glory that they were never to +behold. Many an Emperor has also been decoyed from his throne to the +place of his execution, beguiled by the imaginary charms of an Empress +on whom he was never to cast one passing glance. And these and other +similar captures have been made in places where, without the employment +of the innocent enchantress, perhaps not a single male could have been +found, even after the most diligent search. + +Speaking of this surprising sense, I am again tempted to revert to the +antennae; for it is a remarkable fact that the males of those species of +moths which exhibit the power of thus searching out their mates, are +just those that are also remarkable for their very broad and deeply +pectinated antennae--a fact that has led to the supposition that the +power in question is located in the antennae, and is also proportional to +the amount of surface displayed by these organs. + +Up to the present time we have been considering the butterfly and moth +in their perfect forms, but everybody knows that the former is not +_always_ a butterfly, nor is the latter always a moth; but that they +both pass through certain preparatory stages before they attain their +final winged state. + +We shall now notice briefly what these earlier stages are, leaving the +detailed descriptions of each for the following chapters. + +The life of the perfect butterfly or moth is of very short duration, +often only a few days, nearly the whole of its existence having been +spent in preparing itself for the brief term to be enjoyed + + ... in fields of light, + And where the flowers of Paradise unfold. + +It may be interesting to consider of what use the metamorphoses of +insects are, and to what extent these metamorphoses render them fit for +the work they have to do. + +It is certain that the chief work of insects, taken as a whole, is to +remove from the earth the excess of animal and vegetable matter. If they +are to do this work effectually, it is clear that they must be very +voracious feeders, and also be capable of multiplying their species +prodigiously. Now each of these powers requires the special development +of a certain set of organs, and an abnormal development of one set must +necessarily be produced at the expense of the other. Hence we find +insects existing in two distinct stages, with or without an intermediate +quiescent state, during the first of which the digestive apparatus is +enormously developed, while the reproductive organs occupy but very +little space; then, during the other stage, the digestive apparatus is +of the simplest possible description, and the organs of reproduction are +in a perfect state of development. + +Allowing, then, that the chief work of the insect is the removal of +surplus organic matter, we can see that a large share of its life should +be spent in the larval or grub stage, and that the perfect state _need_ +not occupy any more time than is necessary for the fertilisation of the +eggs that almost completely fill the body of the female at the time of +her emergence from the chrysalis shell. + +Many insects undergo their metamorphoses by slow degrees, but the +_Lepidoptera_, after existing for some considerable period without any +important visible change in structure, pass by a rapid transition into +the next state. Thus, a caterpillar, that has not altered in general +form for several weeks, changes into a chrysalis within the course of a +few days; and again, after a period of quiescence that may extend +throughout the whole of the colder months, becomes a perfect butterfly +or moth within twenty minutes of the moment of its emergence. + +But this suddenness is more apparent than real, as may easily be proved +by internal examinations of the insect at various stages of growth; +showing that we are led astray by the rapidity of _external_ +changes--the mere _moultings_ or castings of the skin--while the gradual +transformations proceeding within are not so readily observed. + +We have already said that the life of the perfect butterfly or moth is +short. A few days after emergence from the chrysalis case, the female +deposits her eggs on the leaves or stems of the plant that is to sustain +the larvae. Her work is now accomplished, and the few days more allowed +her are spent in frolicking among the flowers, and sucking the sweet +juices they provide. But males and females alike--bedecked with the most +gorgeous colours and overflowing with sportive mirth when first they +take to the wing--soon show the symptoms of a fast approaching end. +Their colours begin to fade, and the beauty-making scales of the wings +gradually disappear through friction against the petals of hundreds of +flowers visited and the merry dances with scores and scores of playful +companions. At last, one bright afternoon, while the sun is still high +in the heavens, a butterfly, more weary than usual, with heavy and +laborious flight, seeks a place of rest for the approaching night. Here, +on a waving stalk, it is soon lulled to sleep by a gentle breeze. + +Next morning, a few hours before noon, the blazing sun calls it out for +its usual frolics. But its body now seems too heavy to be supported by +the feeble and ragged wings, and, after one or two weak attempts at +play, incited by the approach of a younger and merrier companion, it +settles down in its final resting place. On the following morning a dead +butterfly is seen, still clinging by its claws to a swinging stem, from +which it is eventually thrown during a storm. + +The tale of the perfect moth is very similar to the above, except that +it is generally summoned to activity by the approach of darkness. + +We see, then, that butterflies and moths exhibit none of that quality +which we term parental affection. Their duty ends with the deposition of +the eggs, and the parents are dead before the young larvae have +penetrated the shell that surrounds them. + +Yet it is wonderful to see how unmistakably the females generally lay +their eggs on the very plants that provide the necessary food for their +progeny, as if they were not only conscious of and careful concerning +the exact requirements of their offspring, but also possessed such a +knowledge of botanical science as enabled them to discriminate between +the plant required and all others. + +Has the perfect insect any selfish motive in this apparently careful +selection of a plant on which to lay its eggs? Does the female herself +derive any benefit from the particular plant chosen for this purpose? In +most cases, certainly not. For it often happens that the blossom of this +plant is not by any means one of those that supply the sweets which +insects love, and still more frequently does it occur that the eggs are +deposited either before the flowers have appeared or after they have +faded. + +Neither can we easily impute to the insect an acquired knowledge of the +nature and wants of her offspring, or an acquaintance with botany +sufficient to enable her to distinguish plant forms. Our only solution +of the problem (which is really no solution at all) is to attribute the +whole thing to that inexplicable quality which we are pleased to term +_natural instinct_. It is to be observed, however, that it is not _all_ +butterflies and moths that display this unerring power. Some few seem to +deposit their eggs indiscriminately on all kinds of herbage. But, I +believe, the larvae of these species are generally grass feeders, and +would seldom have to travel far from any spot without meeting with an +acceptable morsel. + +[Illustration: FIG. 10.--THE FOUR STAGES OF THE LARGE WHITE BUTTERFLY +(_Pieris Brassicae_). _a_, larva; _b_, pupa; _c_, imago; _d_, egg.] + +But we must now pass on to a brief consideration of the other stages of +the insect's existence. After a time, varying from a few days to several +months, the young caterpillars or larvae make their appearance. They soon +commence feeding in right earnest. Their period of existence in this +state varies from a few weeks to several months, and even, in some +cases, to years. During this time their growth is generally very rapid, +and they undergo a series of _moults_ or changes of skin, of which we +shall have more to say in a future chapter. Then, when fully grown, they +prepare for an apparently quiescent form, which we speak of as the +_pupa_ or chrysalis, and in which they again spend a very variable +period, extending over a few days, weeks, or months. Now, inclosed in a +protective case, each pupa is undergoing a remarkable change. Some of +its old organs are disappearing, and others are developing; and, after +all the parts of the future insect have been developed as far as its +narrow shell will permit, it bursts forth into the world as a perfect +insect or _imago_. + +Its wings at first are small, shapeless, and crumpled in a most +unsightly fashion; but it is not long before they assume their full +size, beautiful form, and gorgeous colouring. Then, in about another +hour or two, the wings, at first soft and flaccid, have become +sufficiently dry and stiff to bear their owner rapidly through the air. + +We have thus observed some of the more striking features in the +structure of the butterfly and moth in its most perfect state; and +alluded in a very brief manner to the various stages through which these +creatures must necessarily pass before finally reaching this stage. But +now we must study these earlier stages more closely, and watch the +insects during the marvellous transitions they are destined to undergo. +This we shall do in the following chapters. + + + + +CHAPTER II + +_THE EGG_ + + +I suppose you are all acquainted with the general structure of the hen's +egg, having dissected several, in your own way, many a time. + +Its outer covering, which you speak of as the 'shell,' you have observed +is hard and brittle. It is composed of a _calcareous_ or limy substance, +known chemically as _carbonate of lime_. If you put some pieces of it +into an egg cup, and throw over them a little vinegar or any other +liquid acid, you will see them gradually dissolve away, and small +bubbles of carbonic acid gas will rise into the air. Then again, if you +take a long and narrow strip of the shell, and hold one end of it in a +gas or lamp flame, after a short time that end will become softer, and +will glow brightly in the flame, for it is converted into lime--the same +substance that is used by the builders for making their mortar--and the +bright glow is really a miniature _lime light_, such as is always +produced when a piece of lime is made intensely hot. + +Just inside this shell you have seen a thin membrane or skin that is +easily peeled off the substance of the egg itself. Next to this comes +the 'white' of the egg, which is really colourless while liquid, but +turns white and more or less solid in the cooking. Last of all, in the +centre of this, you have noticed the oval yellow mass that is termed the +'yoke' or 'yolk,' and which contains the embryo of the future chick. + +Now if you imagine this egg to be reduced in size till two or three +dozen of them would be required to form a single line about one inch +long, the outer calcareous shell to be entirely removed, the skin or +membrane to be converted into a firmer substance of a horny nature, and, +finally, the yolk to be absent and the whole internal space to be filled +with the 'white,' you will then have some idea of the nature of the egg +of a butterfly or moth. + +To put the matter more briefly, then, we will say that the eggs of these +insects are simply little liquid masses, usually of a colourless +substance, surrounded by a horny and flexible covering. + +Such a description may certainly give you some idea of the nature of the +eggs of insects, but no amount of book reading will serve the purpose so +well or be so pleasant as the examination of the eggs themselves. During +the summer months very little difficulty will be experienced in finding +some eggs in your own garden. Turn over some leaves and examine their +under surfaces, choosing especially those plants which show, by their +partially eaten leaves, that they are favourites with the insect world. +Or you may amuse yourself by catching a number of butterflies--common +'Whites' are as good for the purpose as any--and temporarily confine +them in a wooden or cardboard box, containing a number of leaves from +various plants, and covered with gauze. In this way you are sure to +obtain a few females that have not yet laid all their eggs; and if you +watch your prisoners you will soon see them carefully depositing the +eggs on the under surfaces of leaves, bending their abdomens round the +edges if there is not sufficient room to get themselves completely +under. And then, when you are satisfied with the number of eggs thus +obtained for your examination, you can have the pleasure of seeing all +your liberated captives flying joyfully in the free air. + +In giving these simple instructions I have assumed that the reader has +not yet learnt any of the characters by which female butterflies are to +be distinguished from their lords and masters; but I hope that he will +know soon, at least with regard to a good many species, from which +individuals he may most reasonably expect to obtain eggs, and so be able +to avoid the imprisonment, even though only temporary, of insects which +cannot satisfy his wants. + +Again, it is not necessary, after all, that butterflies should be +captured for the purpose of obtaining eggs. Watch them as they hover +about among your flowers. Some, you will observe, are intent on nothing +but idle frolicking; and you may conclude at once that _these_ have no +immediate duty to perform. Others are flying without hesitation from +flower to flower, gorging themselves with the sweets of life: these are +not the objects of your search. But you will descry certain others, +flying round about the beds and borders with a steadier and more +matronly air, taking little or no notice of their more frivolous +companions, and paying not the slightest heed to the bright +nectar-producing cups of the numerous flowers. These are seriously +engaged with family affairs only. Watch one of them carefully, and as +soon as she has settled herself on a leaf, walk steadily towards her +till you are near enough to observe her movements. She will not move +unless you approach too closely, for, like busy folk generally, she has +no time to worry about petty annoyances. You will now actually witness +the deposition of the eggs exactly as carried on in the perfect freedom +of nature; and the eggs themselves may be taken either for examination +or for the rearing of the caterpillars. + +Some species of _Lepidoptera_ lay some hundreds of eggs, and it is +seldom that the number laid by one female is much below a hundred. + +As already stated, the under surfaces of leaves are generally chosen for +the deposit of eggs, but a few of the insects we are considering always +select the upper surface for this purpose. Thus the Puss Moth (page +235), and two or three others resembling it, though much smaller, known +as the Kittens (page 234), invariably lay them on the upper surface. And +this is the more surprising since the eggs of these moths are brown or +black, and consequently so conspicuous on the green leaves as to be in +danger of being sighted by the numerous enemies of insects. + +The Hairstreak Butterflies (page 183) afford another exception to the +general rule, for their eggs are deposited on the _bark_ of the trees +and shrubs (birch, sloe, elm, oak, and bramble) on which their larvae +feed. + +At the moment each egg is laid it is covered with a liquid sticky +substance, so that it is immediately glued to the leaf or stem as soon +as it is deposited. The sticky substance soon dries, causing the egg to +be so firmly fastened in its place that it is often impossible to force +it off without destroying it completely. + +Some of the _Lepidoptera_ deposit their eggs singly, or in small +irregular clusters; but by far the larger number set them very regularly +side by side, in so compact a mass that it would be impossible to place +them on a smaller area without piling one on top of another. This is not +accomplished with the aid of the sight, for the insect performing her +task with such precision often has her head on one side of a leaf or +stem while arranging her eggs on the other. If you take the trouble to +watch her, you will see that she carefully _feels_ out a place for each +egg by means of the tip of her abdomen immediately before laying it. + +The eggs are laid by moths and butterflies at various seasons of the +year. In some cases they are deposited early in the spring, even before +the buds of the food plants have burst; and the young larvae, hatched a +few weeks later, commence to feed on the young and tender leaves. Then, +throughout the late spring, the whole of the summer and autumn, and even +till the winter frosts set in, the eggs of various species are being +laid. + +Those deposited during the warm weather are often hatched in a few days, +but those laid toward the autumn remain unchanged until the following +spring. + +In this latter case the frosts of the most severe winter are not capable +of destroying the vitality of the eggs. In many instances the perfect +insect or the larva would be killed by the temperature of an average +winter day, but the vitality of the eggs is such that they have been +subjected to a temperature, artificially produced, of fifty degrees +below the freezing point, and even after this the young larvae walked out +of their cradles at their appointed time just as if nothing unusual had +occurred. + +Experiments have also been performed on the eggs with a view of +determining how far their vitality is influenced by high temperatures. +We know that the scorching midsummer sun has no destructive influence on +them, but these experiments prove that they are not influenced by a +temperature only twenty degrees below the boiling point--actually a +considerably higher temperature than is _necessary_ to properly cook a +hen's egg. + +Let us now examine a number of eggs of different species, that we may +note some of the many variations in form and colour. + +With regard to colour, we have already observed that the eggs of a few +species are black; but more commonly they are much lighter--pearly +white, green, yellow, and grey being of frequent occurrence. + +The great variety of form, however, will provide a vast amount of +enjoyment to anyone who possesses a good magnifying lens or a small +compound microscope. Some are globular, others oval; while many others +represent cups, basins, and domes. Then we have miniature vases, flasks, +bottles with short necks, and numerous figures that must remind a +juvenile admirer of the sweet cakes and ornamental jellies that have so +often gladdened his longing eyes. + +Again, the beautifully sculptured surfaces of a large number are even +more striking than their general shapes. Some are regularly ribbed from +top to bottom with parallel or radiating ridges, and at the same time +marked with delicate transverse lines. Others are beautifully pitted or +honeycombed, some ornamented with the most faithful representation of +fine wicker-work, while a few are provided with a cap, more or less +ornamental, that is raised by the young larva when about to see the +world for the first time. A few of these beautiful forms are here +illustrated and named, and another has already appeared on page 14, but +an enthusiastic young naturalist may easily secure a variety of others +for his own examination. + +[Illustration: FIG. 11.--EGG OF THE MEADOW BROWN BUTTERFLY.] + +[Illustration: FIG. 12.--EGG OF THE SPECKLED WOOD BUTTERFLY.] + +[Illustration: FIG. 13.--EGG OF THE VAPOURER MOTH.] + +It may be surmised from the accompanying illustrations that the form of +the egg is always the same for any one species. This is really the case, +and consequently an experienced entomologist can often decide on the +name of the butterfly or moth that deposited a cluster of eggs he +happens to find in his rambles and searchings; but in such decisions he +is always greatly assisted by a knowledge of the food plants of the +various insects, and sometimes also by the manner in which the eggs are +arranged. + +We have seen that the period during which the _Lepidoptera_ remain in +the egg stage is very variable, and depends largely on the season in +which they were laid; but it is often possible to tell when to expect +the young larvae by certain changes which take place in the appearance of +the egg. As the horny covering of the egg is transparent, the gradual +development of the caterpillar from the clear fluid can be watched to a +certain extent; but if you have a microscope, and would like to witness +this development to perfection, proceed as follows. + +Arrange that some butterflies and moths shall lay their eggs on strips +of glass of convenient dimensions for microscopic work--three inches +long by one wide is the usual size for this kind of work. This is easily +accomplished by placing a proper selection of female insects in a rather +small box temporarily lined with such 'slips.' When a few eggs have thus +been secured, all you have to do is to examine them at intervals with +your microscope, always using the reflector so as to direct a strong +light _through_ the eggs from below. + +But even without such an arrangement some interesting changes are to be +observed. As a rule, the colour of the egg turns darker as the time for +the arrival of the infant larva approaches, and you will often be able +to see a little brown or black head moving slightly within the 'shell.' +You may know then that the hatching is close at hand, and the movements +of the tiny creature are well worth careful watching. Soon a small hole +appears in the side of the case, and a little green or dark cap begins +to show itself. Then, with a magnifier of some kind, you may see a pair +of tiny jaws, working horizontally, and not with an up-and-down motion +like our own, gradually gnawing away at the cradle, till at last the +little creature is perfectly free to ramble in search of food. + +Strange to say, the young larva does not waste a particle of the horny +substance that must necessarily be removed in securing its liberty, but +devours it with an apparent relish. Indeed, it appreciates the flavour +of this viand so highly that it often disposes of the whole of its +little home, with the exception of the small circular patch by which it +was cemented to the plant. When the whole brood have thus dispensed with +their empty cradles, there remains on the stem or leaf a glittering +patch of little pearly plates. + +After the performance of this feat the young caterpillar starts off in +life on its own account with as much briskness and confidence as if it +had previously spent a term in the world under the same conditions; but +we must reserve an account of its doings and sufferings for our next +chapter. + + + + +CHAPTER III + +_THE LARVA_ + + +In almost every case the young caterpillar, on quitting the 'shell' of +the egg, finds itself standing on and surrounded by its natural food, +and immediately commences to do justice to the abundant supply. It will +either nibble away at the surface of the leaf, removing the soft +cellular substance, so that the leaf exhibits a number of +semi-transparent patches when held up to the light, or it will make +straight for the edge, and, closing its horizontal jaws on either side, +bite the leaf completely through, and thus remove a small piece each +time. + +[Illustration: FIG. 14.--THE CATERPILLAR OF THE CLOUDED YELLOW +BUTTERFLY.] + +Several naturalists have amused themselves by performing experiments and +making calculations on the efficiency of the masticating and digesting +powers of the caterpillar. The illustrious R['e]aumur, for example, proved +that some of the cabbage eaters disposed of more than twice their own +weight of food in twenty-four hours, during which time their weight +increased one-tenth. Let us see what this would be equivalent to in +human beings: A man weighing eleven stone would devour over three +hundred pounds of food in a day, and at the end of that day weigh about +fifteen pounds more than he did at the beginning! + +So the young caterpillar eats, and rests, and grows, till, while still +young, its body has become too large for the already tightened skin. It +evidently feels very uncomfortable. Its appetite fails, and it remains +for a time perfectly quiet in one spot, having previously spun a little +carpet of silk to form a firm foothold during its temporary +indisposition. Its colours have also become dingy, and anyone, not +understanding the character of its growth, might easily be led to +suppose that the poor creature was displaying the earlier symptoms of a +serious and perhaps fatal illness. + +But soon an encouraging symptom is observed. The caterpillar begins to +get restless. Its front segments are turned alternately right and left, +and are also made to swell out much beyond their normal size. Then in a +very short time--often less than a minute from the first appearances of +restlessness--the skin, which has become somewhat dry and brittle, +splits along the back over the second, third and fourth segments, +revealing a new and bright coat beneath. The caterpillar continues its +struggles and, in addition to the previous movements, causes the +swelling to move backward along the body. This, acting like a wedge, +causes the rent in the old coat to extend in that direction. + +[Illustration: FIG. 15.--THE CATERPILLAR OF THE DARK GREEN FRITILLARY +BUTTERFLY.] + +The caterpillar now draws its head backward, and, with a few convulsive +struggles, pulls the front segments out of their old skin, and passes +its head out of the rent in the back. With its foremost segments thus +rendered perfectly free, it walks straight out of the old garment, which +is left still fixed by the legs to the silken carpet. + +The larva, although now fresh and smart in its appearance, is exhausted +by these struggles and its prolonged fast. The new skin, moreover, is +very soft and tender, even to the cases of the head and legs, which are +normally very hard. But a short period of rest suffices to dry its skin +and sharpen its appetite, and then it eats more vigorously than ever. + +We will now leave the caterpillar for a moment while we look at its +cast-off clothes. They are still clinging to a stem so firmly that they +can scarcely be removed without injury. The hard shell that covered the +head and jaws is perfect in form, and so are the claws and cases of the +legs. All the hairs or spines that happened to adorn the previous owner +still retain their positions; and the whole skin, although always more +or less shrivelled, is sometimes so slightly altered in form that it +might be mistaken for a living caterpillar if not closely examined. + +But this is not all. For, according to the accounts of some +authoritative observers, the lining of the digestive organs, which is +really a continuation of the outer skin, is cast off (or rather cast +_out_) at the same time, as are also the linings of the larger breathing +tubes which are presently to be described. + +We have seen that some caterpillars, on quitting their egg cases (which +may really be regarded as the first moult), make their first meal of the +old covering. So also some of them, in their future moultings, exhibit +an apparently useless economy (seeing that they are surrounded by an +abundance of their natural vegetable diet) by devouring their old coats! +In the face of this fact we can hardly describe them as strict +vegetarians. + +[Illustration: FIG. 16.--THE CATERPILLAR OF THE PURPLE EMPEROR +BUTTERFLY.] + +Having thus passed through its first hardship, the caterpillar has by no +means seen the end of the troubles and dangers that beset it; for, +during its existence in the larval state, it has to go through a series +of three, four, five, or even six moults, all of which are periods of +considerable inconvenience, and perhaps even pain, and frequently prove +fatal. And it is by no means an uncommon thing to meet with the lifeless +body of an unfortunate individual who, as shown by its shabby appearance +and the silken carpet under its feet, has evidently fallen a victim to +the dangerous process of ridding itself of an old garment. + +But this is only one of the many dangers to which caterpillars are +exposed. Throughout every hour of the day the sharp and hungry eyes of +the numerous insect-eating birds are searching the leaves for such +delicacies to satisfy the wants of themselves and their broods. The +lively little lizards, too, during the sunny hours are busily engaged in +searching them out among the foliage of heaths and banks. + +Very formidable enemies also exist in the form of Ichneumon and other +species of flies, which pierce the skins of caterpillars with their +sharp _ovipositors_, and lay their eggs within the bodies of the +unfortunate victims. As soon as the young larvae are hatched from these +eggs, they commence feeding on the fatty substance stored beneath the +caterpillar's skin. They carefully avoid, at first, attacking the vital +organs of their host's body, and in this way secure for themselves a +more lasting supply of fresh food. When the fatty substance is nearly +all gone, they eat their way into the more important structures, of +course steadily growing all the time; and so, even though the body of +the caterpillar is rapidly diminishing, the total bulk shows often no +very appreciable decrease in size. When the larvae of the flies are fully +fed, they either change to the pupa within the carcase of their host, or +eat their way out of its body and construct for themselves a cocoon in +which to undergo the transformation. + +As for the caterpillar itself, it sometimes dies before the time for its +metamorphosis has arrived; but it often changes to the chrysalis before +its fate is sealed. In this latter case, a number of flies, having +undergone their final transformation within the chrysalis shell (there +being but little else than shell remaining of the victim's body), break +forth from the remains of the carcase somewhere about the time at which +the butterfly or moth should have appeared. + +[Illustration: FIG. 17.--AN ICHNEUMON FLY (_Cryptus Migrator_).] + +[Illustration: FIG. 18.--ANOTHER ICHNEUMON FLY (_Pimpla Instigator_).] + +Caterpillars have also their nocturnal enemies and devourers, among +which may be mentioned frogs, toads, newts, and insect-eating mammals. + +We must now learn something of the structure of caterpillars; and then +become acquainted with their habits, and the change to the chrysalis or +pupa. + +Take a caterpillar from your garden, preferably a full-grown one of a +rather large species, that is not very densely covered with hair, and +examine it carefully as we note the main points in its structure. The +first point that strikes our notice is the division of its body into +segments or rings, separated from each other by a more or less distinct +line or slight constriction of the body. + +There are thirteen of these segments, reckoning, as is usual, the head +as the first. + +The head is usually very hard, and often of a much darker colour than +the rest of the body. It is also frequently divided into two lobes by a +couple of oblique lines, between which the parts of the mouth are +situated. The two powerful horizontal jaws, to which we have already +referred, are very hard and sharp, and curved like a sickle, and +therefore splendidly adapted for biting from the edges of leaves. The +head is also provided with a pair of antennae, usually very short and +inconspicuous and protected by a horny covering. + +Unlike the perfect insect, the caterpillar has no large compound eyes, +but twelve very small simple eyes, situated on the cheeks, very near the +mouth--six on each side. + +[Illustration: FIG. 19.--THE CATERPILLAR OF THE ANGLE SHADES MOTH +(_Meticulosa_).] + +If you examine them with a magnifier, you see that each one is provided +with a small and very convex lens--a lens of very _short focus_, such as +would be used for the examination of small objects held very near to the +eye. From this arrangement we should be inclined to conclude that the +caterpillar can see only those objects that are close to its mouth; and +this idea is strengthened if you place one in a box containing a number +of leaves, one of which is that of its own food plant. It will wander +about the box, apparently looking at every part of every leaf it passes, +after the manner of a very short-sighted individual, and never taking a +general look round. A butterfly or a moth can see a flower in the +distance, for it flies unhesitatingly from one to another in the +straightest and shortest path, but if you place a caterpillar in the +centre of a ring composed of a leaf of its food plant and nine others +from other plants, the chances are (nine to one) that it will _not_ walk +towards what it would like to have. + +Again, the eyes are situated on the _lower_ part of the cheek, directed +slightly downward, and are therefore adapted for seeing what is just +under its jaws as it walks along. Had we no knowledge whatever of the +caterpillar's twelve little eyes, we should probably have thought that +it sought out its food by some sense other than that of vision. + +Another important and interesting feature of the head is the +silk-spinning apparatus, situated under cover of the lower lip. This +consists of two tubular glands, corresponding to our own salivary +glands, the special purpose of which is to secrete a viscid fluid that +solidifies on exposure to air. The opening by which the fluid escapes is +so situated that the caterpillar can easily apply it to the surface of +any object over which it is walking, and then, by drawing or turning +away its head, cause a silken fibre to be produced. + +Some caterpillars make use of this spinning apparatus only on a few +special occasions, but others, more especially some of the smaller +species, seem to have it always in use, so that if at any time you +suddenly start them into the air by giving a smart tap to the plant or +twig on which they rest, they invariably fall slowly on the end of a +growing web, the spinning of which they stop as soon as they consider +they have fallen far enough. Sometimes, as you are walking through a +wood, you will see hundreds, nay, thousands of little caterpillars thus +suspended, swinging gently in the breeze. Not long since, after only a +few minutes' walk among the trees of Epping Forest, I found I was +decorated with several dozens of these swingers with which I had come +into collision--in this case consisting chiefly of the larvae of the +Green Tortrix Moth (_Tortrix viridana_). + +Now let us examine the caterpillar's limbs. Attached to each of the +second, third, and fourth segments is a pair of true walking legs, +corresponding with those of the perfect insect. These are covered with a +hard and shining substance, and are also each provided with a hook. The +fifth and sixth segments have no limbs at all, nor have the eleventh and +twelfth, but some or all of the others (seventh, eighth, ninth, tenth, +and thirteenth) are furnished with a pair of claspers which we shall +presently describe. + +First, as regards the number of claspers, it will be seen from what has +just been said that this is not always the same. Some caterpillars +possess five pairs, thus making up the total number of walking +appendages to sixteen. In fact, we must regard this as the _usual_ +number. But there are at least a few hundred exceptions to the rule. +Many of the _Bombyces_ (page 217), for example, have only four pairs of +claspers; and in others of the same group the fifth pair is present, but +only partially developed, and quite useless for walking. + +Look at the peculiar caterpillar of the Lobster Moth (fig. 23)--a +creature that differs from most other caterpillars not only in its +claspers, but in many other respects too. Observe its long and slender +legs, its humped middle segments, and its upturned hindermost segment, +of enormous size and mounted with a pair of clubbed 'horns.' This last +segment you will observe, has no claspers. + +[Illustration: FIG. 20.--WALKING LEG OF A CATERPILLAR.] + +[Illustration: FIG. 21--LARVA OF THE YELLOW UNDERWING MOTH (_Pronuba_).] + +[Illustration: FIG. 22.--LARVA OF THE CRIMSON SPECKLED MOTH +(_Pulchella_).] + +[Illustration: Fig. 23.--LARVA OF THE LOBSTER MOTH (_Fagi_).] + +Another allied caterpillar is that of the Iron Prominent Moth (fig. 24). +This one also has humped segments, and the claspers of the thirteenth +segment are imperfectly developed. + +A large number of other exceptions to the general rule are to be found +in the caterpillars of the Geometer Moths (page 268), one of which is +here represented. These have generally only two pairs of claspers, one +pair on each of the tenth and last segments, so that there is a distance +equal to the combined length of six segments between the hindermost true +leg and the first pair of claspers. But even among the Geometers there +are variations to be observed in the number of claspers, and some of +these will be pointed out in our brief descriptions of the commoner +species. + +[Illustration: FIG. 24.--CATERPILLAR OF THE IRON PROMINENT MOTH +(_Dromedarius_).] + +[Illustration: FIG. 25.--LARVA OF THE BRIMSTONE MOTH (_Luteolata_).] + +These limbs which we have been calling claspers are known by several +other names. Thus they are termed 'pro-legs,' 'temporary legs,' 'false +legs,' and 'abdominal legs;' but if you watch a caterpillar as it walks +up a stalk or along the edge of a leaf, you will certainly agree that +the term 'clasper' is everything that could be desired. But why not call +them legs, seeing that they are used in walking? The reason is that they +differ in many respects from the three foremost pairs of limbs as +regards structure, persistency, and function. The true legs, as we have +called them, continue to exist, though concealed, in the chrysalis +state, and again appear, far more perfectly developed, in the butterfly +or moth, but the claspers are no more to be seen after the caterpillar +has passed into the quiescent stage. We have noticed, too, that the true +legs are pointed and clawed, also that they are protected by a hard and +horny covering; but examine a large caterpillar, holding it between the +fingers and thumb with its under side uppermost, and you will soon see +that the claspers are not at all hard, but soft and fleshy; not pointed, +but often terminating in a broad flat circular surface. You will also +observe, as the creature struggles to escape from your grasp, and tries +to get a hold on something with its claspers, that these limbs, if we +may so call them, are retractile, and are sometimes completely drawn +into the body. Finally, examine the broad end of a clasper with a +magnifier, and you will see it surrounded by a circle of little hooks, +turning in all directions. You will no longer wonder how it is that a +caterpillar can hold so tenaciously to a piece of twig that it is often +almost impossible to remove it without injury. + +Now put your caterpillar down, so that you may observe its gait. If it +happens to be one with the full complement of sixteen limbs, you see +that at each stride it makes but little progress. The segments contract +and relax alternately and in succession, thus sending a series of +wave-like motions along the body, and urging onward the front segments +while the claspers keep the hinder portion firmly fixed. + +[Illustration: FIG. 26.--THE CLASPERS OF A CATERPILLAR.] + +But if your caterpillar is one of the Geometers, with only two, or +perhaps three, pairs of claspers, the mode of procedure is very +different. The creature stretches its body out at full length, often +raising its head high in the air, and swinging its long body right and +left with a most furious motion, as if to hastily scan the +neighbourhood. Then, having satisfied itself as to the _direction_ of +its proposed course (which, by the way, is often changed considerably at +almost every stride), it holds on by the true legs and pulls its hinder +quarters forward till the body forms almost a closed loop, with the +fourth segment nearly touching the ninth. The claspers now become the +holdfasts. The little hooks with which they are provided are firmly +fixed to the surface on which it is walking; and the body being again +straightened out to its utmost length, the same man[oe]uvre is repeated. +So, you see, the insect progresses by strides equal in length to about +six segments of the body, and these the longest segments generally; and +the rate at which the strides succeed each other, especially in some of +the smaller species, is really astonishing. + +We have seen the caterpillar in the act of taking its walk, and now we +will give it a twig of its food plant so that we may see it feed. It +walks up the twig without hesitation--for caterpillars (excepting those +which feed on roots) always seem to move upward when in search of +food--and soon finds itself on a leaf. Over this it walks till it +reaches the edge; and, grasping the edge firmly between the claspers, so +as to give perfectly free play to its legs and head, it stretches its +body at full length, and takes a series of bites as it brings its head +backward in a curve. When the head has thus been brought close to its +fore legs, the body is again extended, and the same ground is gone over +again. + +If the caterpillar is a fairly large and hardy one, it will bite through +the smaller veins, and perhaps even the larger ones; but the smaller +species often change their position on reaching a moderately thick vein, +and so devour little else than the soft cellular substance of the leaf. +In any case, it is astonishing to see how rapidly the leaf disappears +under the influence of the powerful jaws and marvellous digestive +apparatus of the hungry grub. + +Those who take a delight in watching the _movements_ of caterpillars are +sure to be interested in observing them when at rest; for at such times +the various attitudes assumed are as pleasing and instructive as are +their active moments. And these attitudes are all the more interesting +on account of the mimicry by which the creatures often baffle their +numerous enemies. We may profitably spend a little time in studying a +few cases in point. + +Many species, when at rest, fix themselves by means of their claspers to +a small twig or leaf stalk, or on the midrib of the leaf itself. Here +they remain perfectly still, with their bodies perfectly straight or +with head slightly raised. I need hardly say that these generally fix +themselves on the _under_ side of the leaves and stalks, thus securing +themselves against the attacks of the feathered foes above. But some +birds are equal to the caterpillars in this matter; and it is really +amusing to see them hopping about beneath the leaves in our gardens, +every now and again slyly turning one eye upward, and smartly plucking +an unwary grub from its resting place. + +The precautions of the caterpillar, however, do not end merely with the +selection of an under surface. You will find that the bright green +species invariably settle on a leaf or a _green_ stalk, while the darkly +coloured insects often choose a twig covered with a brownish bark. Some +even make for the _trunk_ of the tree on which they feed, and here +remain quite still in a vertical position, so that they look just like a +ridge in the bark, the colour of which is faithfully imitated by their +skin. Further, many of the caterpillars that resort to this stratagem +have bodies that are notched or knotted and spotted in such a manner +that the resemblance to their surroundings is so perfect as to defy any +but the most experienced eye. And even this is not all, for a number of +these mimics of the insect world never venture to feed by day, but take +in their quantum of provisions during the dark hours, and practise their +deceptions throughout the day. + +Most of the Geometer caterpillars, of which we have already spoken, are +well trained in the art of deception. You are out on a caterpillar hunt, +and engaged in carefully turning over the twigs of the hazel or some +other shrub, so that you may the more readily examine the under surfaces +of the leaves. At last you lay hold of a small broken twig for this very +purpose. To your astonishment it is very soft, and readily bends between +your fingers. You look more closely at this peculiar piece of stick, and +find, to your surprise, that you have grasped a looper caterpillar that +was standing out at an angle just like a broken twig, supported by its +two pairs of claspers, and coloured and knotted exactly like the little +branch on which it rested. + +At other times you meet with little green caterpillars of the same +group, supporting themselves in exactly the same manner on a small twig, +and looking just like a leaf stalk from which the blade had fallen or +been devoured. + +What a wonderful power is exhibited in the grasp of the claspers and the +tension of the muscles, enabling the caterpillar to fix itself and +retain its position for so long a time! Imagine an acrobat fixing +himself by his hands on an upright pole, throwing out his body at an +angle, and without any further support retaining his position motionless +for several hours! + +Other experiences of the larva hunter are equally interesting and, +perhaps, even more tantalising. He is engaged in very cautiously turning +over the leaves of a certain food plant from which he hopes to obtain +the larva of a much-coveted species. Then, just as his eye catches a +glimpse of the very object of his search, down falls the caterpillar, +rolled up into a little ball, among the herbage below. This latter is +diligently and patiently examined. But no, the anticipated prize is +nowhere to be seen. It is probably a green one, and this adds to the +difficulty of the patient entomologist. Then, as he carefully separates +the low herbs, hoping to find the spot where the larva had fallen, the +insect, rolled up into a compact little ball, only sinks deeper and +deeper into the maze. + +Many caterpillars avoid capture in this manner, while others seek to +avoid detection by remaining perfectly motionless, even when roughly +handled. They allow themselves to drop from their resting place on the +slightest sign of danger, and, when the alarm is over and all is quiet +again, they ascend the food plant and resume their position. + +Some caterpillars not only rest, but even feed under cover, quite secure +from most, if not all, of their enemies. Several of them feed on roots, +and many a farmer can relate sad experiences of the havoc committed by +these caterpillars on his turnips and other crops. Then there are those +which feed on flowers and buds, completely burying themselves in the +dense mass of food. + +[Illustration: FIG. 27.--THE HOMES OF LEAF MINERS AND LEAF ROLLERS.] + +We must conclude this brief account of resting and hiding places and +attitudes of caterpillars by a few observations on the leaf miners and +leaf rollers. + +The former are very small caterpillars--the larvae of certain small +moths--that eat burrows into leaves without doing any considerable +injury to the outer _epidermis_, and thus prepare a safe resting place +within the substance of their food. + +The latter, also mostly of small size, make themselves secure by curling +a leaf or a portion of a leaf into a cylinder, and holding it in +position by means of a number of silken threads. + +If you examine a leaf thus curled you will soon be convinced that a +considerable number of the extremely delicate threads must be necessary +to hold it in position; but, if you would like to know how a very small +and feeble caterpillar can manage to roll up a comparatively large and +rigid leaf, you must watch the little creature at its work. + +You need have but little difficulty in finding a willing worker, for +such caterpillars are extremely numerous. Take a few out of their +self-made homes, place them on a sprig of the food plant, and you will +soon have the pleasure of seeing one start its extraordinary work. + +At first it spins a number of threads stretching from the edge of a leaf +to about the middle of the surface. These threads are not tight by any +means, and the leaf is, as yet, unchanged in position. But now the +little mechanic exhibits a tact that almost seems to prove a knowledge +of the principles of its art. Each thread in turn is pulled _at right +angles_ at its middle, and then fastened by means of the creature's +spinneret. Each time this is done the edge of the leaf is bent round _a +little_; and when at last the cylinder is completed, a number of other +threads are stretched across from the scroll to the flat part of the +leaf to secure it firmly in its place. + +Many caterpillars are solitary in their habits: that is, they are always +found singly, whether walking, resting, or feeding. But a large number +of species are gregarious, living in dense clusters either throughout +their larval state or, perhaps, only while young. In many such cases it +is difficult or even impossible to find any reason for this gregarious +tendency--to discover any advantage that the insects may derive from the +habit. Many species, however, are true co-operators in the defence of +their communities. The caterpillars of such live in clusters, sometimes +several scores in each, and all help in the spinning of a complicated +mass of silk fibres, which, with the leaves and twigs they join +together, form a safe home in which they can rest, feed, or change to +the chrysalis state. In early summer hundreds of such caterpillar +'nests' are to be seen in many of our hawthorn and other hedgerows. + +Before closing our general account of the caterpillar we must have a +word to say about the breathing apparatus, more especially as in our +future descriptions we shall frequently have to mention the colours and +markings which surround the openings in its body through which the air +supply is admitted. + +If you examine the sides of the segments of a caterpillar, using a lens +if the insect is a small one, you will observe some little round holes, +often inclosed in a ring or a patch of some prominent colour. These are +the _spiracles_ or openings of a series of air tubes called _tracheae_. +These latter divide and subdivide within the body of the caterpillar, +the branches of one often uniting with those of another, thus forming a +really complicated arrangement of air pipes by which the supply of +oxygen is distributed. + +A microscopic examination of a portion of one of the tracheae will show +that its walls are supported by an elastic spiral of a firm substance. +This arrangement serves to keep the air passages open, and secures for +the caterpillar a free supply of air at times when a contraction of the +segments would otherwise cause the tubes to collapse. + +There are nine spiracles on each side of the caterpillar's body, and +never more than one in the side of the same segment. The head, which we +have been regarding as the first segment, has no spiracles. The second +segment has a pair--one on each side. There are none in the third and +fourth; but all the segments, from the fifth to the twelfth inclusive, +have each a pair; the last (thirteenth) segment has none. + +We have already observed the general arrangement of the caterpillar's +limbs; but perhaps it may be interesting and even convenient to the +reader to give here a little table that will show at a glance the +disposition of both limbs and spiracles. + + First segment--head Two short antennae, two jaws, + and twelve eyes. + Second " Legs and spiracles. + Third " Legs only. + Fourth " Legs only. + Fifth " Spiracles only. + Sixth " Spiracles only. + Seventh " Spiracles, and sometimes + claspers. + Eighth " Spiracles, and sometimes + claspers. + Ninth " Spiracles, and sometimes + claspers. + Tenth " Spiracles, and generally + claspers. + Eleventh " Spiracles only. + Twelfth " Spiracles only. + Thirteenth " Claspers only, and these + occasionally absent. + +We must now watch the caterpillar through its later days, to see how it +prepares for passing into the pupal stage, and to witness the various +interesting changes that take place at this period. + +When fully grown, it ceases to eat, and begins to wander about in search +of a convenient spot for the coming event. Its colours fade, and the +body becomes appreciably smaller, especially in length, as it ejects the +whole contents of its digestive apparatus. According to some accounts, +it even evacuates the lining of the intestines with their contents. + +A great variety of situations are chosen by the different species at +this time. Some will fix themselves on their own food plant, and there +remain till they finally emerge in the perfect state, suspending +themselves from a silken carpet, hiding themselves in a rolled leaf, or +constructing a cocoon of some kind. A large number walk down the food +plants, and undergo their changes in moss that happens to lie at the +foot; or construct a cocoon on the surface of the ground, utilising for +the purpose any decayed leaves, fragments of vegetable matter, or pieces +of earth or small stones. Many seek a further protection than this, and +burrow into the soil, where they either lie in a little oval cell that +they prepare, or in a cocoon constructed by spinning together some +particles of earth. Again, there are those caterpillars, chiefly of +butterflies that frequent our gardens, which find their way to the +nearest wall or fence, and there secure themselves in a sheltered nook. +We will watch a few of these varied methods of procedure, taking as our +first instance the caterpillar of the common Large White or Cabbage +Butterfly. + +When fully fed, this larva seeks out a sheltered spot, generally +selecting the under surface of some object, or of the ledge of a wall or +fence. Sometimes it will not even leave its food plant, though it +generally walks some considerable distance before a suitable shelter is +found. Having satisfied itself as to the site of the temporary abode, it +sets to work at spinning a silken carpet. At first the threads spread +over a rather wide area, and seem to be laid in a somewhat irregular and +aimless manner; but after a little time its labours are concentrated on +one small spot, where it spins several layers of silk fibres. + +This done, it fixes the little hooks of the claspers firmly in its +carpet bed, and then proceeds with a highly interesting movement. It is +not satisfied with only the one mode of suspension. In fact, this alone +would hardly be safe, for when it casts its skin, as it is shortly about +to do, its claspers will all disappear; and although it afterwards +secures itself by the 'tail,' it would be dangling in such a manner as +to swing with every breeze--a very unsatisfactory state of affairs, +especially with those that pupate late in the summer and remain in the +pupal state throughout the winter storms. + +Its next procedure, then, is to make a strong silk band round the middle +of its body, so as to keep it close to the surface against which it +rests. But how is this to be done? It bends its head round till the +spinning organ can be applied to a point close beside the middle of its +body. Here it fixes one end of a thread; and then, gradually twisting +its body, brings its head round to the other side, still keeping it +close to the same segment, and fastens the other end of the thread +exactly opposite the point at which it started. + +The head is now brought back to its former position, thus adding another +thread to the band; and the process is repeated several times, till at +last the caterpillar is satisfied with the thickness and strength of the +cord formed. + +Now it straightens out its body as if to rest from its labours; but the +work is not yet complete. Soon it exhibits much restlessness. Its +foremost segments are seen to shorten, and consequently become thicker. +Then the skin splits, and the last moult of the caterpillar commences. +The movements that follow are exactly similar to those we have already +described in connection with one of the earlier moults: the alternate +and successive contractions of all the segments gradually force back the +old coat, and this is finally thrown entirely off by a somewhat vigorous +wriggling of the 'tail.' + +Then, for a moment, the creature is supported only by its silken cord. +But this lasts _only_ for a moment. For, as soon as it is quite free +from the old garment, it applies its tail to the densest part of the +carpet it had prepared at the start, and secures its hinder extremity by +means of little hooks. + +But what a change has now come over the creature! It is no longer a +caterpillar. Its head is no longer distinct, although we can readily +make out the positions of the eyes. Its mouth and jaws have quite +disappeared, and the legs and claspers are apparently gone. The three +segments that bore the legs are no longer distinctly separable, though +in reality they still exist. The head and thorax are peculiarly shaped; +and, instead of being cylindrical, are angled and ridged; but, beneath +the soft greenish skin--the new garment--we can discern the outline of +a pair of small wings, and see a proboscis and a pair of long antennae. +Also the six long legs of the future butterfly can be traced with care. + +The abdomen is conical in form, coming to a sharp point at the end, and +its segments are quite distinct. + +No stranger to the metamorphoses of insects would connect the present +form with that of a caterpillar; they are so very unlike. And yet the +time occupied in the whole change, from the spinning of the carpet, does +not occupy more than about thirty or thirty-five hours. + +The apparent suddenness of this change is really surprising, but in +reality the transformation is not nearly so sudden as it appears. +Dissection of a caterpillar a few days before the final moult is due +will show that the changes are already going on. In fact, a simple +removal of the skin will prove that the organs of the future butterfly +are developing. Still, in proportion to the short time occupied, the +change is extremely great; and it may reasonably be inquired, Why so +great a change within so short a space of time?--why is not the change +continued steadily and equally through the larval existence? The reason +has already been hinted at. Caterpillars are living eating machines, +whose office is to remove excess of vegetable matter. Consequently they +must have their jaws and bulky digestive apparatus in full development +to the end. If these organs were to _gradually_ disappear as the +caterpillar reaches its non-eating stages, it would simply be starved to +death. So the change from the larval to the pupal state, which we may +regard as the final moult of the caterpillar, is a far greater change +than any of the preceding ones, and occupies a proportionately longer +time, although it is principally confined to the last few days of the +caterpillar life. + +A number of caterpillars, and especially those of the butterflies, +suspend themselves when about to change; and the peculiarities of the +modes adopted must be left for our descriptions of species in a future +chapter; but we will find room here for one more interesting example, +taking this time the larva of one of the commonest of the Vanessas (page +166)--the Small Tortoiseshell Butterfly. + +The caterpillars of this insect are gregarious when young; and if ever +you meet with one, you are almost sure to be able to obtain a hundred or +so without much searching. But as they grow older they feed singly, yet +generally without straying very far from their birthplace. + +When full grown they sometimes stray to a neighbouring plant or fence to +undergo the change to a chrysalis, but more commonly they are perfectly +satisfied with the protection afforded by the leaves of their food +plant. We will now watch one of these as we did the larva of the Large +White Butterfly. + +Of course the under side of the leaf is chosen. Here a silken carpet is +spun as before described; but the caterpillar, instead of clinging with +_all_ its claspers, suspends itself in a vertical position by its +hindermost pair only. + +Here it hangs, head downwards, awaiting the coming events. The splitting +and casting of the skin goes on just as in the case of the Large White, +but there is this puzzle to be solved: how can the insect shuffle itself +out of its old coat without falling to the ground, leaving the cast-off +garments still hanging by the hooks of the claspers? This really seems a +matter of impossibility, since the little hooks which alone suspend the +insect are thrown off with the skin of the claspers. + +The thing is managed in this way. As the skin slowly splits through the +wrigglings of the apparently uncomfortable occupant, it is gradually +pushed backward--that is, upward--till it is in a shrivelled condition, +and the body of the insect is nearly free. But the chrysalis thus +brought to light is provided with little hooks on the end of its 'tail' +by which it can attach itself to the irregularities of the crumpled +coat. Its conical abdomen is also very flexible, and it can, by bending +this, seize hold of a ridge in the skin, holding it between the +segments. Thus, although practically quite free from the old garb, it +never falls to the ground. + +There is now, however, another point to be attended to. The newly formed +chrysalis desires to be entirely independent of its cast-off skin, and +to suspend itself directly from the silky carpet it has prepared. To +this end it works steadily for a time, alternately bending its supple +abdomen from side to side, gripping the folds of the skin between the +segments, pulling its body a little higher at each movement, and +securing itself at each step by the little hooks at its extremity. + +So it climbs, and at last it reaches the network of silk fibres, and +thrusts the tip of its abdomen among them till some of the hooks have +taken hold. Not satisfied with this, it turns its body round and round +to get the little hooks so entangled between the silk fibres that a fall +is impossible, and in so doing it frequently pushes the old skin out of +its place so that it falls to the ground. + +Although the caterpillars of this species do not show any great +gregarious tendency when nearly full fed, yet it is not an uncommon +thing to find several hanging from the under surface of one leaf, all +being attached to the one common carpet at which all had worked. And +when bred in confinement, a number will often spin in company in a +corner of their cage. I have thus obtained a cluster of thirty-seven +pupae, all hanging by the 'tails' to the same mass of silk, which was so +small that they formed quite a compact mass of beings with their tails +close together. + +[Illustration: FIG. 28.--THE COCOON OF THE EMPEROR MOTH.] + +[Illustration: FIG. 29.--THE COCOON OF THE SIX-SPOTTED BURNET +(_Filipendulae_).] + +We have seen that the Large White Butterfly makes itself secure by a +silk band round its middle, while the 'Tortoiseshell' is fixed only by +its tail. But the extra provision for the safety of the former is not so +necessary in the case of the latter, as it never spends more than two or +three weeks in the pupal state. Here it is the perfect insect that +braves the winter, and not the chrysalis. + +There is a great variety in the means taken by the caterpillars of moths +to protect themselves during their metamorphoses, but we shall have +space for only a few illustrations. + +A clever cocoon is spun by the larva of the Emperor Moth (_Pavonia_). It +is pear-shaped, and composed of a brownish silk; and is so constructed +that the newly emerged moth can easily walk out of the small end without +breaking a fibre, while the entry of an insect enemy from without is +impossible. + +This is managed as follows. A number of rather stiff threads are made to +project from the small end of the cocoon, and these converge as they +pass outward so that the ends are all near together. The other portions +of the cocoon are of compact silk, and any insect intruder that ventures +to enter by what we may almost term the _open_ end is met by a number of +spikes, as it were, that play on it at every attempt. Many of these +wonderful cocoons may be found during the winter months attached to the +food plants of this insect. + +Of the silken cocoons spun by various caterpillars some are so thin and +light that the chrysalis can easily be seen through them, and others are +so densely woven as to be quite opaque. A great difference is also to be +observed in the adhesive power of the silk fibres. In some cases little +threads of silk can be pulled off the cocoon; but some of them, that of +the Oak Eggar (page 229) for example, look as if they had been +constructed of paper rather than of silk, because, at the time of +spinning, the moist silk fibres stuck so closely together. + +An extreme case of this character is to be met with in the cocoon of the +Puss Moth (page 235); for here the fluid from the spinneret of the +caterpillar does not harden at once on exposure to air, and so the +threads become thoroughly united together, thus forming a solid gluey +cocoon. + +When the Puss caterpillar is about to change, it descends the tree +(poplar, willow, or sallow) till it is within a few feet of the ground. +Then it commences gnawing away at the bark, at the same time cementing +all the pieces together with the gluey substance from its spinning +glands. In this way it surrounds itself with a very hard cocoon, which +so closely resembles the surrounding bark in colour that detection is +difficult indeed. + +But how will the caterpillar proceed if it is removed from its native +tree and has no bark to gnaw? That you can easily answer for yourself, +or rather Puss will answer it for you. Go and search among the poplars, +willows and sallows in the month of July. You may possibly come across a +caterpillar that is just in the act of creeping down the bark in search +of a resting place; but if not you may be successful in obtaining a few +either by examining the twigs, or you may start them from their hiding +places by smartly tapping the smaller branches with a strong stick. + +Having secured one or more larvae, take them home, and they will give +some rather novel performances. If they are not fully grown, you must +supply them with fresh leaves every day till they refuse to eat; and +then is the time for your experiments. Shut one in a little wooden box, +and you will have the pleasure of watching it construct a cocoon of +chips of wood that it has bitten out with its powerful jaws, all joined +together into a hard shell by means of transparent glue. Shut another +Puss in a glass vessel--a tumbler, for instance--either by placing it +under the inverted vessel, or by covering over the top. Perhaps it will +not be superfluous to mention that, should you place it under an +inverted vessel, this vessel should not stand on a polished table, for, +whatever be the material, unless _extremely_ hard, it is sure to be +utilised in the manufacture of the cocoon. + +Let us suppose, then, that the caterpillar is under an inverted tumbler +that stands on a plate or saucer. Now it is for _you_ to decide what +material shall be used in the construction of the new home. Give Puss +some fine strips of brightly coloured ribbon, and it will construct a +very gaudy house by gluing them together. Or, provide it with sawdust, +pieces of rag, glass beads, sand, paper, anything in fact; and the +material will be 'made up' into a cocoon more or less ornamental +according to the nature of the supply. + +But what if you give it _nothing_ with which to work, and so inclose it +that nothing its jaws can pierce is within its reach? For instance, shut +it in with tumbler and saucer as before, inverting the former on the +latter, and give it no material whatever. What will it do now? We will +watch and see. + +At first it is very restless, and walks round and round the edge of the +tumbler, evidently a little dissatisfied with the prospects. Then, after +a little while, the events of nature transpiring in their fixed order +regardless of trivial mishaps, the glutinous fluid begins to flow from +the creature's spinning glands, and it moves about in a somewhat aimless +fashion, applying the transparent adhesive matter both to tumbler and +saucer. + +It seems now to become a little more reconciled to its unnatural +surroundings; and, making the best of bad matters, keeps its body in one +place, and starts the construction of a ridge or barrier all round +itself. By the continued application of the creature's spinneret this +barrier is made gradually thicker and higher, till at last the +overhanging sides meet and the caterpillar is inclosed in its +self-constructed prison. But the walls of this prison are so transparent +that every movement can be watched; and, after the insect has spent a +few days in completing the cocoon, we can see it cast off its old skin, +and appear in the new garb of a fine greenish chrysalis. + +Its soft green skin soon hardens and turns to a rich dark brown colour, +and it settles down for a long rest lasting till the following May or +June. + +When the whole operation of building is completed, lift up the tumbler, +and up will come the saucer too. The two are firmly glued together by +the substance secreted; and the power of this as a cementing material +will be well illustrated if you endeavour by mere pulling force to +separate the two articles. + +The Puss is not the only caterpillar that works up a foreign material +with the contents of the spinning organs. There are several others, in +fact, that use for this purpose fragments of wood or other parts of the +food plants; and a still larger number bind together leaves, fresh or +dead, or particles of earth or other matter. Several such cocoons will +be described in our accounts of individual species in another chapter. +We shall now devote a little space to a few general remarks on the +chrysalides and the final metamorphosis of butterflies and moths. + + + + +CHAPTER IV + +_THE PUPA OR CHRYSALIS_ + + +As soon as the last moult of the caterpillar is over, the chrysalis that +had already been developing under the cover of the old skin is exposed +to full view; and although the perfect insect is not to be liberated for +some time to come, yet some of its parts are apparently fully formed. + +[Illustration: FIG. 30.--THE PUPA OF THE PRIVET HAWK (_Ligustri_).] + +[Illustration: FIG. 31.--THE CHRYSALIS OF THE LARGE WHITE BUTTERFLY +(_Brassicae_).] + +The newly exposed skin of the chrysalis is very soft and moist, but as +it hardens it forms a membranous or horny covering that protects and +holds firmly in place the trunk and the various limbs and appendages +that are distinctly to be traced on the under surface. + +If, however, you examine a chrysalis directly after the moult is over, +you will often find that the wings, antennae, proboscis, and legs of the +future butterfly can be easily separated from the trunk of the body on +which they lie by means of a blunt needle, and can be spread out so as +to be quite free from that surface. + +In form the chrysalides of butterflies and moths are as variable as the +caterpillars. Many of the former are sharply angular like that of the +'Small Tortoiseshell' already mentioned; but some of the +butterflies--the Skippers (page 197)--have smooth and tapering +chrysalides, and so have most of the moths. + +In colour they are equally variable. Some are beautifully tinted with +delicate shades of green, some spotted on a light ground, some striped +with bands more or less gaudy and distinct, but the prevailing tint, +especially among the moths, is a reddish brown, often so deep that it is +almost a black. + +[Illustration: FIG. 32.--THE PUPA OF THE DARK GREEN FRITILLARY +(_Aglaia_).] + +[Illustration: FIG. 33.--THE PUPA OF THE BLACK-VEINED WHITE BUTTERFLY +(_Crataegi_).] + +As a rule there is no marked resemblance between the different stages of +the same insect. Thus, a brilliantly coloured caterpillar may change to +a dull and unattractive chrysalis, from which may emerge a butterfly or +moth that partakes of the colours of neither. But in a few cases there +_are_ colours or other features that remain persistent throughout the +three stages, or show themselves prominently in two. + +An interesting example in point is that of the Magpie or Currant Moth +(page 279). The caterpillar of this moth is cream-coloured, with orange +stripes along the sides, and very bold black markings down the back. The +chrysalis, which is at first entirely yellow, afterwards turns black +with the exception of some yellow transverse bands. Then, the moth +exhibits the same colours as these two earlier stages, with the same +degree of boldness; for its pale cream-coloured wings, tinted with +patches of yellow, are marked with numerous deep black spots. Thus, in +this case, we find the same general character of the colouring +throughout the insect's existence. + +[Illustration: FIG. 34.--THE PUPA OF THE CURRANT MOTH.] + +[Illustration: FIG. 35.--PUPA OF THE PALE TUSSOCK MOTH (_Pudibunda_).] + +Another interesting example, though not so striking as the last, is to +be found in the case of a group of moths known as the _Liparidae_. The +caterpillars of these are remarkable for their very hairy bodies, often +ornamented by several bold brush-like tufts. The chrysalides are also +hairy; and several of the moths themselves are not only thickly clad +with shaggy hair, but a bold tuft often tips the abdomen. + +We must not leave these few remarks on the characters of chrysalides +without a mention of the brilliant spots of burnished gold that decorate +the pupae of certain butterflies. This is the feature that led to the +invention of the term _chrysalis_, which is derived from the Greek word +_chrysos_, meaning _gold_. For the same reason the term _aurelia_ has +been applied to the pupae of _Lepidoptera_, this being derived from +_aurum_--the Latin name for gold. + +Strictly, then, these two terms apply only to the pupae of a certain +number of the butterflies; but the former is now generally used to +designate the pupae of all the _Lepidoptera_, and is even extended to the +corresponding stages of insects of other orders. + +If you examine one of these gold-speckled chrysalides, the brilliant +metallic lustre seems to belong to the outer surface, just as if certain +spots had been tipped with real gold; but after the butterfly has +quitted its case the beautiful golden spots are gone. This proves that +the metallic appearance is not due to reflection from the outer surface +of the chrysalis, but to a reflection from some structure beneath it. +This latter is a very thin membrane which lies just under the outer +transparent covering of the chrysalis. + +The period during which the _Lepidoptera_ remain in the chrysalis state +varies very considerably in different species, and also depends more or +less on the temperature. As a rule, when a caterpillar pupates before +the end of the summer, it remains dormant in the pupal condition for +only a few weeks; but, if late in the summer or in the autumn, it +remains in this condition throughout the winter, and emerges in the +following spring or early summer. + +Both these conditions are illustrated in the life history of the Large +White or Cabbage Butterfly--an insect with which we have already become +acquainted. We get two distinct broods of this butterfly every year, the +first appearing in May and the second in August. The eggs of the first +brood hatch in about a fortnight, and the larvae are full grown about +four weeks later. These then change to chrysalides, from which the +perfect insects (the second brood) emerge in a few weeks--the period +varying slightly with the temperature of the season. From the eggs of +this second brood we get another invading army of cabbage eaters that +change to pupae late in the summer. These remain dormant till the +following April, and may be found in numbers throughout the winter, +attached to the walls and fences of kitchen and market gardens. + +If, then, the pupae of the same species are so influenced by the +temperatures of the seasons, can we limit or prolong the period of +quiescence by subjecting them to high or low temperatures artificially +produced? Most certainly we can; and every practical entomologist knows +how to obtain the perfect butterflies and moths of certain species long +before their appointed times, or, if he desires it, to compel them to +remain in their dormant stage long after the natural period has +terminated. + +Sometimes an enthusiastic insect hunter obtains a large number of what +we may term 'winter pupae,' by collecting and breeding various species. +He also anticipates a number of successful captures of perfect insects +during the following summer. Thus, from two distinct sources, he obtains +a goodly assortment of butterflies and moths, the setting, preserving, +and arranging of which entails an immense amount of home work. + +Under such circumstances he will sometimes endeavour to cause some of +his pupae to emerge before their accustomed time, so that he may get some +of his insects 'on the boards' before his field work is in full swing, +and so avoid a rush, or prevent the loss of insects that will be spoiled +before he has time to take them in hand. + +This process of hurrying up his pupae he calls 'forcing,' and simply +consists in keeping them for a time in a warm room or hothouse where the +high temperature is pretty constant. + +On the other hand, the entomologist may desire to try the effect of a +continued _low_ temperature on his pupae. This he can do by placing his +pupae in an ice house. Such experiments have often been performed, and +the results are very interesting. In some cases the emergence of the +perfect insect has been delayed for many months, and even years; and +then, after an exposure to a normal temperature lasting only a week or +two, the winged insect has made its appearance just as if nothing +unusual had happened. + +Such are the effects of _extreme_ temperatures on the duration of the +chrysalis state; and we naturally infer, from such results, that the +pupa under natural conditions is influenced, though in a lesser degree, +by the variations experienced with the seasons, especially in such a +fickle climate as our own. + +The insect hunter has always to bear this in mind, and particularly so +when he sets out on a search for certain desired species. Suppose, for +example, he has set his mind on the capture of a certain butterfly that +_usually_ appears in the _first_ week in May. Before finally naming the +day, he has to consider what the weather has been during the last few +weeks, and if he finds that this has been much warmer than the average +for the corresponding periods in the past, he selects a day in _April_, +earlier or later according to the difference between the present season +and the average. + +If he does not pay due attention to such considerations, he will +sometimes find that all the insects netted are shabby and much worn, +even though, under average conditions, he would be catching newly +emerged and brilliant specimens. This, then, will explain how it is that +we so often see in entomologists' periodicals startling accounts of +'early captures,' and of the appearance of certain insects late in the +season that _ought_ not to have emerged till the following summer. + +I will give just one illustration of these variations. The beautiful +Orange Tip Butterfly (Plate I, fig. 7) generally appears about the +middle of May in the southern counties. Farther north it is of course a +little later. In the north of England it has been taken in June; and in +Scotland as late as July. On the other hand, I have taken it in +Gloucestershire as early as March, on a rather bleak day with a cold +east wind; and, withal, in a field on the slope of the Cotswolds fully +exposed to the unfavourable breeze; but it was evident that, in this +case, the butterfly had been enticed from its winter quarters by the +milder weather of the few previous weeks. + +It may be as well, in passing, to observe that it is not only the pupa +that is influenced by temperature. The hatching of eggs may be forced by +high temperatures, or be retarded by exposure to cold; and in nature the +period of incubation varies with the seasons. The larvae, too, grow +faster or more slowly, or pupate earlier or later from similar causes. +And so no very definite date or period can be assigned to any one stage +of any insect. + +Now let us return to one of the chrysalides that we have already watched +through the earlier stages of its existence, and follow it in its future +development. + +It is now, as we say, in its quiescent or dormant condition, but we must +not suppose that it is always in a profound sleep, nor can we say that +it is insensible to its surroundings. Touch it gently or surprise it +with a puff of air from your mouth, and it will begin to wag its pointed +tail, sometimes with such vigour as to send the body rolling round and +round in its box. Lay it on a bed of cocoa-nut fibre or finely sifted +soil and let it remain _quite undisturbed_ for a few hours or days, and +you will probably find that, by occasional movements of its body, it has +made a slight depression in its bed, and lies partly submerged. I have +known some chrysalides to completely bury themselves in this way during +the course of a day or two, and others to partly expose themselves after +having been lightly covered. Others again, I have observed, will move +smartly if a strong light is suddenly turned on them. Many, too, +certainly appear to have a strong objection to exposure to the direct +rays of a hot sun; for, when thus exposed, they will struggle +persistently, as if to work their bodies into some shady corner. I would +not advise a young entomologist to try this experiment, however, if he +values the pupae he possesses, for direct sunlight is undoubtedly very +harmful to many species, and perhaps it is to all. + +Some chrysalides are not nearly so active as has just been represented; +in fact, there are many which seem to show no signs of life during the +greater part of the time spent in that state. But in all, whether +apparently active or not, certain important internal changes are at +work. We have already noticed that, even in the last days of the +_larval_ existence, some of the organs of the future imago are to be +traced. But these are as yet imperfectly developed. We have also +observed that a continuation of these changes, gradually carried on, +would be impossible in a voracious feeder; so the insect, now fully +grown, and no longer requiring a supply of food, settles down in perfect +quiet, submitting itself quite passively to any further changes that +nature may demand. + +It has already suffered the loss of its claspers. Its wonderful jaws +that did so much damage (for good or evil as the case may be) to the +vegetable world are now gone, and the bulky digestive apparatus has +rapidly dwindled to useless dimensions. These and other changes, already +in progress, have to be perfected while the creature is in a restful and +helpless condition, though they may often be retarded or even suspended +during cold weather when progress would certainly bring it to an +untimely end. + +But now the grandest of all these transformation scenes is nigh at hand. +The protective skin is already loosening from the almost perfect imago, +and consequently feels softer and far more yielding than it did when in +close contact with the body: the swaddled butterfly or moth (for such +the pupa is) is slowly preparing to throw off its imprisoning garb. The +wings and large compound eyes are assuming their final colours, which +now begin to show themselves through the more or less transparent skin, +and the long legs, the perfectly formed antennae, and the slender +proboscis, all of which are folded closely under the creature's thorax, +now begin to move within their loosened sheaths. + +Now let us watch it closely, for one of the most wonderful sights ever +witnessed by a naturalist is about to be presented to our view. We think +we can observe slight movements; and, it may be, we can actually see the +struggling insect endeavouring to set itself free. The legs and +proboscis are moving within the loosened skin; and lo! as we watch these +motions, the prison wall bursts with a slight snapping noise (at least, +such is the case with some of the larger species), and in a moment out +pop a few long legs which immediately struggle for a foothold. The +proboscis also appears, alternately lengthening itself out and coiling +into a spiral, as if impatient to reach the sweet nectar from the bottom +of some fragrant flower cup. + +[Illustration: FIG. 36--A BUTTERFLY, JUST AFTER EMERGING.] + +All this takes place in less time than one requires to describe it; and, +before many seconds have passed, the struggling insect has quite +completed its last moult, and is bidding good-bye to the rent garment +that has done it good service for so long a time. + +But how dreadfully disappointing! Did we not say only a few minutes +since, that a beautiful butterfly or moth was about to emerge? How, +then, is this? Here is an odd-looking creature, such as we have never +seen before! True, it has the right kind of body, though even that is so +soft and heavy that it is fairly dragged along as the insect walks. Its +antennae, too, seem to be just the right thing--that is, just what we +were expecting to see. But oh! the wings! Are we looking at a +deformity?--a failure on the part of Nature to produce what she ought? + +We will not judge hastily, but continue to watch it a little longer. It +seems very restless at first, and, with the fluttering apologies for +wings, drags its heavy body along till it reaches some surface up which +it can climb. If nothing of the kind is close at hand you may place a +_rough_ upright stick in its path, and it will immediately begin to +ascend. Its motto is now 'Excelsior!' and its ambition to rise may be so +great that, on reaching the very top of the stick provided for it, it +struggles for a still higher position in life till, failing to get a +foothold in the air itself, it falls to the ground and has to retrace +its steps. + +I once thought I would like to test the perseverance of a large moth in +performing its first upward journey; and as it was one from a chrysalis +to be found in nature at the foot of a tree that attains some +considerable height, I was, of course, prepared to exercise a little +patience myself. + +As soon as the moth had emerged, I placed it at the bottom of a window +curtain that hung from about eight feet high to the floor. In less than +half a minute it had reached the top, and was struggling hard to get +still higher. I took it down, and again placed it at the bottom. Up it +went as fast as before; and this was repeated nine times with exactly +the same result. For the tenth time I placed the persevering creature at +the bottom of the curtain; and, after it had walked about halfway up, it +_suddenly_ stopped, apparently quite satisfied with having travelled a +distance of over seventy feet in an upward direction. Its six legs were +immediately arranged symmetrically in a business-like manner, and there +it settled quite still, as if it had some definite object in stopping +just exactly in that spot. + +But we must now return to our own insect, which has by this time settled +itself in a similar manner on the stick we provided for it. The peculiar +organs which represent the wings, though so very small, show distinctly, +in miniature, the colour and pattern of the fully developed wings of the +species. An interesting change is just now commencing. These wings are +apparently growing larger, but the development is very unequal, so that +they become curled and crumpled till they are even more unsightly than +before. All seems to be going amiss. But this lasts only for a short +time. The fluid from the body steadily rushes into the _nervures_, +causing the wings to expand, and in a few minutes the beautiful pinions +are stretched to the full extent, assume their normal shape, and expose +the full glory of their brilliant colours. + +It may be interesting if I give an example showing the exact time taken +for the full development of the wings of a certain insect. So I will +here quote an entry from my note book; and, by the way, let me strongly +advise all my young readers who follow up this subject to habitually +enter in a book kept specially for the purpose all facts which strike +them as they pursue their study of nature. The note to which I refer +runs as follows: + +'Early on the evening of the 22nd [April] I selected a few chrysalides +of Populi [the Poplar Hawk Moth, page 209] which, from the looseness of +their cases, were thought to be just on the point of emerging. At 8.46 +one of them showed signs of restlessness; and, after a few vigorous +movements, during which it rolled itself over on the glass [I had placed +the pupae on a piece of plate glass so that slight movements might be +more easily detected], the front of its case was suddenly thrust off +with considerable force; and in _less than four seconds_ the imago was +quite free and crawling on the table. After trying hard to reach a +higher point than was provided for about four minutes, it rested to +expand its wings--now about seven-sixteenths of an inch long, or +one-third the total length of the body. At 9 o'clock the wings reached +half the length of the body, and were much curled. At 9.12 they were +fully expanded and straightened out.' + +From this extract we see that the whole period from the bursting of the +case to the full expansion of the wings was only twenty-six minutes; and +it will be well to remind the reader that the process occupies even a +much shorter time than this with many species, both of butterflies and +moths. It will be observed, also, that the _evening_ was chosen as the +time for the observation. There was a reason for this. The Poplar Hawk +Moth, as is the case with many others, almost invariably emerges from +the chrysalis in the evening--usually after dark. But it may be +mentioned in passing that a far larger number of the _Lepidoptera_ as +invariably emerge in the morning. + +Again we will return to our newly emerged insect, for there are still +one or two interesting points to observe. The wings have fully expanded, +it is true, but how very limp they are! Take the creature on the tip of +your finger and hold it so that its body is in a horizontal position. +Immediately the wings bend downward with their own weight, so soft and +flexible are they. The body, too, is still very soft, and apparently +much too heavy for flight. Then, if you place it on a flat surface, it +will immediately try to find some perpendicular or overhanging surface +from which it can suspend itself by means of its legs, so that the +pendant and straightened wings are in the best possible position for +drying. As the insect walks away in search of such a resting place, the +body still drags as it did before, and the wings bend over, either both +on one side or one on each side of the body. + +It is some time before the wings are sufficiently dry and rigid for +flight, but the period varies greatly with different species. Some of +the small butterflies and moths take to flight long before an hour has +passed, but in many cases several hours elapse before the creature +starts from its first resting place. Butterflies that emerge in the +morning spend their first day actively on the wing; but the nocturnal +moths that emerge early in the day do not fly till evening twilight. +When, however, the time arrives, the insect flutters its wings as if to +test their power before committing itself to the air; and frequently, +after only a few seconds spent in this preparatory exercise, off it +darts with astonishing rapidity. But others seem far more cautious. They +vibrate their wings, sometimes with such rapidity that they are lost in +a kind of mist, and with such power that their bodies would be carried +suddenly into the air were they not firmly anchored by three pairs of +hooked claws. Then, continuing the rapid vibration, they move slowly +along, always holding on firmly by one or more legs, as if to still +further satisfy themselves concerning the efficiency of their wings. +Then they venture on a few short trial trips from one neighbouring +object to another, and at last gain sufficient confidence for a long +voyage. + +How strange must be the feelings of a winged insect during its first +flight! After a long period during which it was a helpless, crawling +grub, and this followed by a term of imprisonment during which it was +almost or quite shut off from the world, it now suddenly acquires such +great powers of locomotion that it is often a match for ourselves. + +But, alas! this life is short. A few days spent in sporting with those +it meets and in sucking the sweet juices of many flowers; then a day or +two during which the female deposits its eggs; again a few days employed +in pleasures that become less and less attractive, till, at last, the +creature becomes weary of life and settles down to die. + +We have now traced the complete life history of the _Lepidoptera_ from +the egg to the perfect insect, avoiding descriptions that apply only to +certain species as far as possible, excepting where such are useful as +illustrations. + +Only one thing more remains to be done before we start in real earnest +with our practical work. We shall shortly be giving hints on the modes +of capture, the 'setting' and the preservation of butterflies and moths. +And in so doing we shall often have to observe important points in which +our dealings with these two great divisions of the order will differ +very materially. Hence we must not consider ourselves ready to proceed +with the practical portion of the entomologist's labours till we are +perfectly satisfied that we know the main features that enable us to +distinguish between the butterflies and the moths, and also know just a +little concerning the subdivisions on each side. + +This, then, shall form the subject of the next short chapter. + + + + +CHAPTER V + +_CLASSIFICATION OF THE LEPIDOPTERA_ + + +The _Lepidoptera_ are divided into two very unequal groups, to which we +have so frequently alluded as 'Butterflies' and 'Moths.' And, although +these two terms are popularly applied in a fairly accurate manner, yet, +strange to say, very few persons indeed have any definite knowledge of +the differences that entomologists recognise between the two groups. + +Every entomologist has his circle of sympathetic and, perhaps, even +admiring friends. Consequently, many a little package is sent round to +his abode 'with great care,' accompanied by a note or a message +concerning the fine 'butterfly I have just caught, and thought you would +like to add to your collection.' + +The 'butterflies' that so frequently reach us through these channels +nearly always turn out to be _brightly coloured_ moths, and this +naturally gives one the idea that the popular notion as to the +classification of the _Lepidoptera_ is based on colour or brilliancy of +design, the term 'butterfly' being applied to the gayer species, and +'moth' to the more dingy members of the race. + +There is really some shadow of a reason in this method of nomenclature, +for butterflies _are usually_ more brightly clad than moths; but the +scientific classification, at least as far as the main divisions and +subdivisions are concerned, has nothing whatever to do with colour or +design; and we must at once acquaint ourselves with the fact that there +_are_ very dingy butterflies, and most beautiful and highly coloured +moths. + +How shall we account for the fact that the specimens so kindly sent us +by our friends are generally moths? Is it because moths are more +numerous and more frequently seen? They are certainly more numerous; +for, while our butterflies do not number seventy species, the other +division contains about two thousand. Yet, in spite of this fact, moths +are not generally observed as much as butterflies, for the former are +nearly all night-fliers, and the latter _always_ fly by day and rest by +night. + +Still our question remains unanswered. The reason is this. The captives +sent us are seldom caught on the wing. Most of our grown-up friends, +even though they admire our own pluck and general carelessness +concerning the remarks of the spectators of our entomological antics, +would not themselves like to be seen, hat in hand, chasing a butterfly; +and the night-flying moths are, of course, less frequently observed. But +they often, in the course of their daily employments, meet with a large +moth fast asleep in some corner of a dwelling house, workshop, or +outhouse. Such moths are easily caught while in the midst of their +slumbers, and, as they often make no attempt to fly by day, are as +easily transferred to a box suitable for transmission by messenger or by +post. + +In the above few remarks we have alluded to some features by which the +two great groups of the _Lepidoptera_ may be distinguished; but we have +already referred (page 5) to a far more important one in our description +of the various forms of antennae. All butterflies--at least all _British_ +butterflies--have knobbed or clubbed antennae, while the corresponding +organs of all our moths terminate in a sharp point. + +This distinction obtains in all British _Lepidoptera_, and is so far +regarded as the most important basis of classification that naturalists +have derived from it the two Greek terms that are synonymous with our +two popular names--butterflies and moths. The scientific name for the +former group is _Rhopalocera_--a term derived from two Greek words, one +signifying a horn, and the other a club, and thus meaning 'club-horned.' +The corresponding name for moths is _Heterocera_, derived from the same +source, and meaning 'variously horned.' + +But, although we find embodied in these two long and formidable names an +unerring mark of distinction between British butterflies and moths, we +must not neglect other less important facts which, though less +distinctive, are not without interest. + +Observe a butterfly at rest. Its wings are turned vertically over its +back, and brought so closely together that they often touch. In this +position the 'upper' surfaces of the 'upper' wings are completely hidden +from view, and the 'under' surfaces are exposed on the two sides, +except that those of the 'upper' pair are partly hidden by the other +pair. + +Now look at a moth under the same circumstances, and you will generally +find the wings lying over its body, which is almost or completely hidden +beneath them. As a rule the upper pair together form a triangular +figure, and entirely cover the second pair; but in some cases a portion +of each of the under wings extends beyond the margin of those above +them, and in others the upper pair extend so far forward that nearly the +whole of the under wings is exposed behind them. + +[Illustration: FIG. 37.--A BUTTERFLY AT REST (LARGE COPPER).] + +[Illustration: FIG. 38.--A MOTH AT REST (GOTHIC).] + +Again, the wings of butterflies are so rigid that they can never be +folded; but you will observe that the under wings of moths are generally +very thin, soft, and pliant, and are neatly pleated lengthwise when not +in use. + +Another feature deserving notice is a slight difference to be often +observed in the form of the body. The butterfly, which generally has a +slender body, has a distinct constriction or waist between the thorax +and abdomen. This is not so apparent with moths, and especially with the +thick-bodied species. + +The _Rhopalocera_ or Butterflies are divided into _Families_, each of +which contains insects that possess certain features in common by which +they may all be distinguished from the members of any other family. + +The British species represent eight families. They are as follows: + +1. _Papilionidae._--Containing only one British species--the beautiful +Swallow-tail (Plate I, fig. 1). + +2. _Pieridae._--Containing ten species. These are often known +collectively as the 'Whites,' but include four butterflies that are +distinguished by beautiful shades of yellow and orange. + +3. _Nymphalidae._--This family contains seventeen insects, among them +being several splendid species. It includes the Fritillaries and +Vanessas. + +4. _Apaturidae._--Of this we have only one representative--the Purple +Emperor (Plate V, fig. 1). + +5. _Satyridae._--Including the 'Browns' and 'Heaths,' and numbering +eleven species. + +6. _Lycaenidae._--Including the Hairstreaks, 'Coppers,' and 'Blues,' in +all seventeen species. + +7. _Erycinidae._--Containing only the 'Duke of Burgundy.' + +8. _Hesperiidae._--This family contains seven British butterflies +commonly known as the 'Skippers.' + +Although all the members of the same family resemble each other in +certain points of structure, or in their habits, yet we can often find +among them a smaller group differing from all the others in one or two +minor particulars. Such smaller groups are called _Genera_. + +To make this all quite clear we will take an example. + +The Brimstone Butterfly (Plate II, fig. 4) belongs to the second +family--_Pieridae_, _all_ the members of which are distinguished from +those of the other families by the characteristics mentioned on page +141. + +But our Brimstone Butterfly possesses another very prominent feature in +which it differs from all the other British _Pieridae_, and that is the +conspicuous projecting angles of both fore and hind wings. Among the +foreign species of the family we are considering there are several that +possess these angles; but as there are no others among our own members, +the 'Brimstone' is placed by itself in the list of British _Lepidoptera_ +as the only member of the genus _Gonopteryx_ or 'angle-winged' +butterflies. + +Thus the full relationship of this butterfly to other insects may be +shown in the following manner: + + _The Brimstone Butterfly._ + + =ORDER.=--_Lepidoptera_ + =Section.=--_Rhopalocera_ + FAMILY.--_Pieridae_ + _Genus._--_Gonopteryx_ + Species.--_Rhamni_ + +Now, every butterfly has a Latin or Greek name in addition to that by +which it is popularly known. I should have said _two_ Latin or Greek +names. The first of these is always the _generic_ name, and the second +is the one by which we denote the particular member or _species_ of that +genus. Thus, the scientific name of the Brimstone Butterfly is +_Gonopteryx Rhamni_. + +'But,' the reader may be inclined to ask, 'why should we not be +satisfied with the one popular name only?' And, 'If we _must_ have a +separate scientific name, could we not find suitable terms among our +English words to build up such a name--one that might express the +principal characteristics of the insect, and also serve all the purposes +of classification?' + +Such questions sound very reasonable, and so they are. But the +entomologist's answer is this. We ourselves may get on well without the +help of the dead languages, but we have brother naturalists all over the +world, speaking a great variety of different languages. We endeavour to +help one another--to exchange notes and generally to assist one another +in our labours; and this can be greatly facilitated if we all adopt the +same system of nomenclature. The educated of most of the great nations +generally know something of Latin and Greek, and consequently the +adoption of these languages is generally acceptable to all. + +This sounds well, but for my own part I believe that if we are to make +any branch of natural history a popular study, especially with the +young, we must to a certain extent avoid anything that may prove +distasteful. There is no doubt whatever that many a youngster has been +turned away from the pursuit of the study of nature by the formidable +array of almost unpronounceable names that stretch nearly halfway across +a page; and those who desire to make such a study pleasant to beginners +should be very cautious with the use of these necessary evils. One would +think, on glancing over some of the scientific manuals that are written +'especially for the young,' that the authors considered our own too mean +a language for so exalted a purpose, for in such works we find all or +nearly all the popular names by which the schoolboy knows certain +creatures he has seen entirely omitted, and the description of a species +appended to a long Latin term that conveys no idea whatever to the +reader, who is studying the description of a well-known animal or plant +and doesn't know it. + +Our plan will be to give the popular names throughout, except in the +case of those few species that are not so well known as to have +received one; but the scientific names will always be given as well for +the benefit of those readers who would like to know them. And the short +description of the method of classification just given will enable the +more ambitious of my readers to thoroughly understand the table of +British butterflies and moths toward the end of the book. + +This table includes _all_ the British species of butterflies and of the +larger moths; and the arrangement is such as to show clearly the +divisions into sections, families, &c. It will therefore be of great +value for reference, and as a guide for the arrangement of the specimens +in the cabinet. + +In the foregoing description of the method of classification butterflies +only are mentioned; but the division and arrangement of moths is carried +out in just the same manner except that the system is a little more +complicated. The number of moths is so large in comparison, that we are +able to select from them some very large groups the species of which +possess features in common. These groups are termed _tribes_, and are +again divided into families just like the butterflies. Thus the +arrangement of moths includes _tribes_, _families_, _genera_ and +_species_. We will take an example by way of illustration as we did +before, and ask the reader to verify the same by comparison with our +table: + + _Example._--The 'Common Tiger' (Plate X, fig. 3). + + =ORDER.=--_Lepidoptera_ + =Section.=--_Heterocera_ + TRIBE.--_Bombyces_ + FAMILY.--_Cheloniidae_ + _Genus._--_Arctia_ + Species.--_Caia_ + Scientific Name.--_Arctia Caia._ + +I have already said that the Latin and Greek names of butterflies and +moths are not at all necessary to the young entomologist. It is quite +possible to be well acquainted with the natural history of these +creatures, and to derive all the pleasure and benefits that the study of +them can afford without the knowledge of such names; but most +entomologists go in for them, often to the entire exclusion of the +popular English terms. + +There are those who consider themselves (or would have us consider them) +expert entomologists because they have the power to vomit forth a long +list of scientific names of butterflies and moths which (to them) have +no meaning whatever; and it is astonishing that we meet with so many +youngsters who can rattle away such terms, and, at the same time, are +totally ignorant of the real nature of the creatures they name. + +If you wish to be a naturalist in the true sense of the term, study your +_specimens_, and take but little pains to commit their hard names to +memory; and you will then find that the latter will gradually become +your own property without any special effort on your part. Your +continued reference to illustrated works and museum collections will +bring them to you almost unconsciously, and you will generally find your +entomological vocabulary extending as rapidly as your cabinet becomes +filled. + +Again, with regard to the _meanings_ of the scientific terms, don't +trouble much about them. It unfortunately happens that in a very large +number of cases these names are ill chosen, and do not in any way refer +to the distinguishing characteristics of the species to which they are +applied. You will observe, too, if you look at the table, that many +insects have _two_ scientific names applied to the species, one being +placed in brackets after the other. In such cases both these names are +in common use, having both been applied by independent authorities, and +the insertion of the two will prove an assistance at times. + +It is a common practice with entomologists, in their communications, to +use only the second or _specific_ name of insects. Thus, they would +speak of the Brimstone Butterfly as _Rhamni_, and not _Gonopteryx +Rhamni_. When _writing_ a communication, however, they very commonly +place in front of the specific name the initial letter of the first or +_generic_ name. Thus the full title of the butterfly just mentioned +would be abbreviated to _G. Rhamni_. + +Having said so much concerning the principles of classification and +nomenclature, we will pass on to the practical portion of the +entomologist's work. + + + + +PART II + +WORK AT HOME AND IN THE FIELD + + + + +CHAPTER VI + +_CATCHING BUTTERFLIES AND MOTHS_ + + +It is not at all surprising that entomology should prove such a +fascinating study to the young, and more especially that portion which +deals with the department we are now considering. Butterflies and moths +are among the most beautiful and most interesting of living creatures. +The study of their life history is enchanting, and the creatures +themselves are of such a size as to be conveniently handled and +preserved, and withal occupy so little space that anyone with only +moderate accommodation may possess a fairly typical collection. + +Compare the work of the entomologist with that of one whose hobby is the +study of mammals. The latter has to deal with large and cumbersome +objects, a collection of which requires an enormous amount of space; +and, unless he has the time and means to travel in foreign countries, he +cannot get together a good typical collection of specimens representing +his particular branch, for the few British mammals contain no +representatives of several of the orders into which the class is +divided. + +Entomology is undoubtedly, _par excellence_, _the_ study for youngsters. +It is equally suited to the studious and to those of an adventurous turn +of mind. It leads its follower into the bright sunshine and the flowery +meadows; and with body and mind pleasantly occupied, the joy of living +is deeply felt. The necessary apparatus can be made by anyone. No +dangerous gun is required, and there are no precipitous rocks to scale. +When the autumn flowers fade the year's work of the entomologist is not +done, for the arranging of his cabinet and the demands of his living +specimens keep him more or less actively engaged until the flowers of +the following spring call both him and the insects he loves once more +into the field. And so, season after season, and year after year, he +finds himself engrossed in labours so fascinating that idleness--the +curse of so many of our youths--is with him an impossibility. + +I assume that the readers of this book have a desire to take up the +study of one branch of entomology--that of butterflies and moths--in +real earnest; that they intend not only to _read_ about these +interesting insects, but to _know_ them. And there is only one way in +which one may really get to know living creatures; that is by searching +them out in their haunts, observing their growth and habits, and by an +occasional close examination in order to become acquainted with their +structure. + +Hence I shall in this, the practical portion of the work, give such +information as will assist the beginner in catching, preserving, +rearing, breeding, and arranging the specimens that are to form his +collection. + + +_Catching Butterflies_ + +There was a time when we would try to capture a butterfly at rest on a +flower by a quick sweep of the hand, or, more commonly, by a sharp +downward stroke of the cap. We were led to this action by a mere +childish love of sport, or by a desire to possess an insect simply +because it was pretty. When we succeeded in securing our prize, we +handled it somewhat carelessly, often passing it from one hand to the +other, or boxing it in our closed and perspiring fist till our fingers +were dusted with the pretty microscopic scales of the creature's wings, +and the wings themselves, stripped of all their beautiful clothing, were +merely transparent and veined membranes. Having thus carelessly but +unintentionally deprived the creature of its greatest beauty, we set it +free, often in such a damaged or exhausted condition that the poor thing +could scarcely fly. + +But our childish ideas and inclinations have vanished. Now we would +rather watch the insect than catch it, for we find much pleasure and +interest in its varied movements. And if for purposes of study we +occasionally require to make one captive, we proceed in such a manner as +to preserve its beauty unimpaired. The cap now gives place to a +well-made and suitable net; and we are careful to provide ourselves with +sufficient and proper accommodation for our captives. + +It is probable that many of my readers are as yet unacquainted with the +nature of an entomologist's requirements for field work, so we shall +describe them, confining ourselves at first to those that are required +for a butterfly hunt. + +First and foremost comes the net. This essential portion of your +equipment may be either purchased or constructed by yourself. Very +little skill is required to enable you to do the former. Provided your +pocket is well charged, you may start off at once to the dealer in +naturalists' appliances, and treat yourself to a complete outfit. But +even in this case a little advice may not be out of place. See that what +you purchase is very _strongly_ made. You can get nicely finished nets +constructed on the most convenient principles, made to fold and go in an +ordinary coat pocket, but with _weak joints_. See that you have the most +convenient form of net by all means, but do not go in for convenience +and appearance at the expense of strength and durability. Nothing is +more annoying than to find your net give way just when you are in the +midst of a good day's sport. + +[Illustration: FIG. 39.--A WIRE FRAME FOR A BUTTERFLY NET.] + +[Illustration: FIG. 40.] + +The folding net is certainly very convenient, for you can conceal it in +your pocket while you are walking through town or travelling in a +railway carriage, and thus avoid that contemptuous gaze which certain of +the public are prone to cast on a poor 'bug hunter.' And although such +nets are generally purchased, yet they _may_ be constructed by anyone +who has had experience in the working of metals. But other forms of +nets, equally useful and even stronger, can be made by anybody; and I +will give a few hints on two or three different ways of putting them +together. + +A very simple and strong frame for a net may be made as follows: Get a +piece of stout iron or brass wire about forty inches in length, and bend +it into a circle with the two ends, turned out about two inches each, at +right angles to the circumference as shown in the accompanying sketch. + +Now take a good tough stick, the length of an ordinary walking stick, +and cut out two grooves opposite each other at the end, just large +enough to take the straight ends of the wire. The end of the stick will +now resemble fig. 40 in shape. Place the ends in their grooves, and bind +them tightly to the stick by a good many turns of rather fine wire. + +A frame well made after this fashion is as strong as anything you could +desire, but it has the disadvantage of being always fixed to the handle, +thus preventing the use of the latter as a walking stick when you are +not directly engaged in your entomological work. + +A much more convenient frame may be made by thrusting the ends of a +piece of cane into the two narrow arms of a metal Y. You may purchase +the Y at any of the naturalists' stores, or you can make one yourself if +you know how to perform the operation of soldering. I have always made +mine with odds and ends of brass tubing such as old gas pipes. One piece +must be just the size to fix on the stick; and the other two must fit +the cane tightly. The three pieces must be filed off at the proper +angles, and the doubly bevelled end of the wider tube must then be +flattened down to the width of the smaller ones before soldering. If you +decide to buy one, give the preference to strong brass rather than the +cheaper and more fragile ones made of tinned iron. + +[Illustration: FIG. 41. THE METAL Y.] + +The advantage of such an arrangement over the last frame is evident at +once. The cane, with net attached, can be pulled out of the Y when not +in use, and bent small enough to go in the pocket or a satchel; and the +Y can also be separated from the stick, thus allowing the latter to be +used as a walking stick. + +Some entomologists speak very favourably of what is known as the +'umbrella net'--a large and light net that will shut up like an +umbrella, and may even be made to look very much like this useful +protector, but the possession of such an imitation is somewhat +tantalising in a pelting shower. The ring of this net consists of two +steel springs attached to a couple of brass hinges, one of which is +fixed near one end of the handle, while the other slides up and down in +the gamp fashion. + +One other form of net--'the clap net'--although still occasionally seen, +has had its best days. Two sticks are provided to this one, so that the +two sides of the net may be brought together on the insect; but as both +hands are required to manage it, it is almost surprising that it ever +had any advocates at all. + +When your frame is completed, sew round it a strip of strong calico, to +which the net itself may be afterwards sewn, for the lighter material of +the net is too delicate to stand the constant friction against the metal +or cane frame. + +The material usually employed in making the 'bag' is called leno. It can +be purchased at most of the drapers' shops, and three colours--white, +yellow and green--are usually kept in stock. Measure the circumference +of your net frame, and see that you get sufficient leno to make a good +full net. Suppose, for instance, that the circle of your frame measures +thirty-six inches round, then your leno should be at least forty inches +in length. Fold this double, and then cut out two pieces of the shape +shown in fig. 42, letting the depth of the net be nearly or quite equal +to the width of the material. There is nothing to be done now but to +stitch the bag together and sew it to the calico on the ring. + +[Illustration: FIG. 42.] + +At first you will find the leno rather stiff and harsh, but a damping +and good rubbing between the hands will soften it down; or, if you +prefer it, you may soften the material by a slight washing before +cutting out the net. The latter is perhaps the better plan, for the +washing will remove the objectionable 'dressing' that renders the +material rather hard and stiff. + +Of the three colours mentioned above, green is the one most generally +chosen, because it is more in harmony with the surroundings of a +butterfly catcher; but many prefer the white leno to the green, as the +insects are more easily seen in a net of this colour. Yellow is +certainly not a desirable tint. + +As a rule it will be necessary to kill an insect as soon as it is +captured. This is always the case with butterflies unless you require to +keep them alive either to watch their movements or to obtain eggs. For +this purpose you will require a killing bottle or box containing some +volatile substance. + +The selection of this necessary piece of apparatus is a point deserving +of much consideration, for so many different forms are in use by +different entomologists, and so many advocates each declare that his own +plan is far superior to that of any of the others, that the final +decision is not to be worked out in a moment. The best thing for a +beginner is to try as many as he can, and then, after some considerable +experience of his own, he will be able to decide which apparatus suits +himself best. + +I recommend this because it is impossible to say of any one plan that it +is the best, for that which gives perfect satisfaction to one individual +will often fail to give anything but annoyance in the hands of another. + +To enable my young readers to follow the advice I have just given, I +will describe some of the commonly used killing arrangements and show +how they should be used. + +I will take first the 'cyanide bottle.' This is a wide-mouthed bottle, +containing a very poisonous substance called _cyanide of potassium_. It +is fitted with a good sound cork. The 'cyanide' is a solid substance, +and must be fixed in some way or other at the bottom of the bottle so +that it cannot shake about and damage the butterflies. + +[Illustration: FIG. 43.--THE CYANIDE BOTTLE.] + +A cyanide bottle can be purchased ready for use at the cost of a +shilling or thereabouts; but if you are old enough to be trusted with +deadly poisons, you may buy the 'cyanide' of a chemist who knows you +well and is satisfied as to your intentions, and then prepare your own. +Every entomologist should know how to do this, for the poison loses its +power after some time, and it is not always convenient to leave your +bottle in the hands of a chemist or a 'naturalist' to have it recharged. +This will cost you more than it would to do it yourself, but that is +nothing compared with the annoyance that may result when, the night +before an anticipated butterfly hunt, you are calmly told that 'your +bottle will be ready in a few days.' You can charge it yourself in a few +minutes if you can manage to keep a small supply of 'cyanide' in stock, +and it is ready for use very shortly after. + +Here is the _modus operandi_.--Purchase an ounce or two of the cyanide +of potassium, and immediately put it into a stoppered or well-corked +bottle. Label it at once, not only with the name, but also with the word +POISON in very large and conspicuous letters. This dangerous chemical is +often sold in sticks that look much like certain 'sugar sticks' I was +acquainted with in my younger days; but whether this is or is not the +case with your cyanide, see that the bottle is kept quite out of the +reach of the inquisitive and sugar-loving juveniles of the house. + +The quantity above mentioned is more than you will require for the first +'charge,' but you will soon experience the convenience of having a +supply always at hand for recharging when your cyanide bottle fails to +do its work expeditiously, or when an accident calls for the somewhat +sudden appearance of a new one. + +Now procure a bottle for your work. Its mouth must be wide enough to +take the largest insect you hope to catch, and the widest part of the +bottle need not be much larger. Get a perfectly sound cork to fit it +tightly; and, to insure the more perfect exclusion of air, paint over +the top of the cork with melted paraffin wax. + +Dissolve a few drams of the cyanide in a little water, using a glass rod +to stir up the mixture till the solid has all disappeared; and be +careful that neither the solid nor the solution touches the skin if it +should be in the slightest degree scratched or broken. Now sprinkle +plaster of Paris into the solution, a little at a time, and stir all the +while. As soon as the mixture begins to set, pour it into your bottle as +cleanly as you can--that is, without touching the sides--and press it +down with the flat end of a stick if it is not level. Now cork it, and +put the bottle away in a cool place till required for use. + +This is, I think, the best way of charging the bottle; but there are two +other common methods that may, perhaps, be regarded as a little more +simple. One is this: put a few small lumps of the 'cyanide' into your +bottle, and then cover them with a stiff mixture of plaster of Paris and +water, and press down as before. The other plan is to cover the +'cyanide' with a few thicknesses of blotting paper, cut just a little +larger than the inside of the bottle. The first of these two methods is +fairly satisfactory, but I have always found that the charge, when made +in this way, has a tendency to become wet and pasty, in which condition +it will spoil the wings of the insects. The other is very objectionable, +especially for field work, for the blotting paper fails to keep its +place while you are on the chase. If the plaster is used, the mixing +must be done quickly and without hesitation, or the mixture will become +solid before you can press it into your bottle. + +We will not enter now into the _pros_ and _cons_ of the cyanide bottle, +but will consider the advantages and disadvantages of the various +methods of killing the insects after we have noticed a few more. + +The 'laurel box' has had many devoted advocates, although it does not +seem to be much in use now. It is a very good arrangement, however, but +is a little more troublesome than the cyanide bottle, as it requires +frequent replenishing. + +A very good laurel box may be prepared as follows. Get a small tin box +of cylindrical form, measuring about five inches by two, and cut a +circle of perforated zinc or wood just the size to fit it snugly as a +false bottom without any danger of falling out of its place. Now gather +some of the young leaves of the green laurel bush, and beat them almost +to a pulp with a mallet or hammer. Place this in your tin box, and press +down the perforated false bottom on it. The bruised laurel leaves give +off a very powerful odour, which stupefies butterflies immediately. + +[Illustration: FIG. 44.--SECTION OF THE LAUREL BOX. + +_a_, space for insects; _b_, perforated partition; _c_, bruised laurel +leaves.] + +Of course the reader may be able to think of various other ways in which +the laurel box may be made. Any arrangement will do providing the vapour +can come to the insects without allowing the leaves to touch their +wings; and any ingenious youth could manufacture a more satisfactory +article than the one I have mentioned. My desire is, as far as possible, +to give instructions that may easily be carried out by anyone, even if +he has not the slightest mechanical skill, leaving the clever youth, +sometimes, the opportunity of displaying his own inventive power. But in +this case I will give a few suggestions concerning other ways in which a +laurel killer may be constructed. A firm and _fixed_ false bottom is a +decided advantage. This is easily managed by fixing a circular piece of +perforated zinc or 'tin' by means of a little solder; or even a wood +partition may be used, fixed with a few brads, driven into it from the +outside. With the fixed partition, however, you must have a lid at each +end of the box. This is easily managed if you get two tins of the same +size, knock out the bottom of one, and fit the lid of the other in its +place. + +I have heard of laurel boxes without any partition save a piece of rag +in which the bruised leaves are wrapped. The whole is _pressed_ into the +box so firmly that it is not likely to be displaced while you are on the +chase. I do not recommend this, for in addition to the chance of its +slipping there is a danger of the sap of the leaves exuding through the +rag and spoiling the insects' wings. But if the reader should prefer to +try this on account of its simplicity, it will probably occur to him +that a bottle may be used instead of a tin box. + +A well-made laurel box, with a fixed metal partition, is a piece of +apparatus strongly to be recommended to all young entomologists who +desire to test the relative value of the various poisons that are used +by the different experts; for with it any one of these substances can be +used. In the poison compartment you can place pieces of 'cyanide' +wrapped in blotting paper, or any kind of porous substance moistened +with liquid ammonia, chloroform, benzole, or any other volatile liquid +insecticide. All the above-named substances are declared to be 'the +best,' so they must all be worth the trial. + +'Cyanide' is valued on account of its lasting powers. A cyanide bottle +well charged will retain its efficiency throughout a whole season. I +always recharge two in the spring, one for active service in the field +and the other as a reserve force; and these kept in a cool place do good +execution throughout the year. If they should exhibit a slight failing, +a few minutes' warming before a fire will improve them; but for field +work it is better to recharge. At the same time see that the corks are +in good condition. + +Next to the 'cyanide,' the bruised laurel takes the first rank for +permanency; but you must not expect this to last many days. For a few +days' continuous work one charge will suffice, but if the laurel box has +not been in use for some time you must have a fresh supply. + +The liquid poisons, such as ammonia, chloroform, and benzole, are so +volatile that they are very powerful for a short time, but so much +vapour is lost each time the box is opened that it is absolutely +necessary to carry a bottle of the one you use into the field with you. +Also see that you have sufficient of the blotting paper or other +absorbent to prevent the liquid from leaking through the perforations of +the partition. + +If you choose ammonia--a substance that is not regarded as a poison, and +is therefore easily obtained from any chemist--always get the strongest, +and see that it is labelled 'Liq. Ammonia, S.G. .880' as a guarantee. A +small bottle such as you can conveniently carry in the waistcoat pocket +will contain sufficient for a day's work. Use only a few drops at a +time, but renew frequently. Although the ammonia corrodes cork, yet a +good cork is far preferable for the pocket to a glass stopper, for its +elasticity prevents it from losing its hold, and the liquid from +saturating your pocket and its surroundings; but a glass stopper is +certainly better for the stock solution kept at home. + +Most of the above remarks apply equally well to benzole and to +chloroform, but the latter is so powerful a poison that a very little is +required for a day's work, and consequently a very small bottle is more +convenient. The dealers in naturalist's appliances supply metal +'chloroform bottles' with screw stoppers and a small nozzle that will +allow the liquid to run out only in drops. This is a very good +arrangement, since it enables you to avoid the 'drop too much' which is +not only unnecessary and therefore wasteful, but saves you from +experiencing the disappointment of an empty bottle before your work is +half done. + +[Illustration: FIG. 45.--THE CHLOROFORM BOTTLE.] + +Some entomologists recommend the solid carbonate of ammonium instead of +liquid ammonia, but this is not so powerful. It must be remembered that +we have the butterflies to consider, as well as our own convenience, in +the selection of the poisons we use. It is the opinion of many +well-known entomologists that 'insects cannot feel pain,' and that we +are therefore at liberty to deal with them in any way we please. Still +it is as well to save all possible suffering, and be satisfied with no +killing box that is not practically instantaneous in its effects. + +Among other poisons used by entomologists I may mention sulphur fumes +and tobacco smoke. The former may be obtained by burning a little +sulphur or a sulphured lucifer match under the perforations of a killing +box of the pattern described, and the latter--well, every smoker knows +that. I should at once condemn the former method, at least for field +work, as troublesome and inconvenient; and as to the other, I have tried +the effect of a puff (and many puffs) of tobacco smoke on an imprisoned +insect, but was so dissatisfied with the result that I am not likely to +do so again. + +We have now considered a good many insecticides more or less suitable to +our purpose, but there still remains the unsolved problem as to which is +the best. Each one has its advantages. For _convenience_ nothing beats +the cyanide bottle. It is very speedy in its action, and the use of a +bottle is a little preferable to a metal box, for you can always satisfy +yourself as to its efficiency without opening it. Cyanide, chloroform, +benzole, and some others render the insects more or less brittle and +stiff, so that it is not so easy to 'set' them for the cabinet. Perhaps, +if you happen to have a supply of growing laurel close at hand, you +cannot do better than stick to the laurel box. The time taken in +bruising up a few leaves is inconsiderable, and the moisture given off +from them will keep your insects moist and supple, or will even 'relax' +them if they have become rigid. But try various plans for yourself, and +you will be able to settle a question which all the entomologists in the +world cannot answer for you--which method answers best in _your_ hands. + +The next item for our consideration is the 'collecting box.' This is +merely a box in which the butterflies are pinned as soon as they are +dead. Here, again, we shall note a few variations from which a selection +can be made according to the means or the ingenuity of the reader. For a +couple of shillings you can obtain a good zinc collecting box, lined +with cork, of oval form (a most convenient shape for the pocket), and +quite large enough for one day's captures; and half that modest sum will +purchase a wooden box, also lined with cork, adapted to the same +purpose. + +As with many other things, so with collecting boxes, the cheapest is +often the dearest in the end. You may feel inclined to save a shilling +by buying a wooden box, but you are sure to discard it after a little +practical experience for a metal one. We shall speak a little later on +concerning the advisability of 'setting' the butterflies as soon as +possible after capture; but this is not always practicable, especially +after a good day's catch. Now, if the insects are pinned in a wooden +box, they soon become dry and rigid, and consequently cannot be 'set' +till they have been put through the more or less tedious process of +'relaxing.' If you use a wooden collecting box you will often find, on a +hot and dry day, that all or nearly all your butterflies are rigid +before you arrive home; but a metal box will keep them moist and supple, +so that you can even put off the setting till the following day if you +are unable to do it immediately after your return. + +Another point worth considering is the best economy of space. If your +collecting box is only about one inch deep inside, you have room for +only one layer of pinned insects; but a box only a little deeper may be +lined with cork both at top and bottom, and thus be made to accommodate +double the number. The zinc boxes sold by the dealers are generally +lined with cork in this manner, and are, of course, deep enough for the +double layer of specimens; but the wooden boxes are sometimes lined on +the bottom only. After these few remarks you will at once see the +economy of expending the extra shilling on the former. + +Although the prices of collecting boxes are low, yet there are many who +would prefer making their own, and there is much to be said in favour of +this. A great deal of pleasure is to be derived from the construction of +your own apparatus, especially when that apparatus is afterwards to be +used in the pursuit of a delightful hobby. During the whole of the time +thus engaged, you are looking forward with the most pleasurable feelings +to the glorious treat before you, and every joint you make seems to +bring you nearer to the realisation of your joys. During the bleak +winter months there is no better employment for an entomologist who has +a little spare time than the preparation for the next outing. It is just +one of those artful schemes by which he seeks to get as much pleasure +out of life as it is capable of affording. How many there are who, for +the lack of a pleasant and instructive hobby, find their leisure hours +the most dismal of all, and who complain of the toil and wearisomeness +of their lot! The mournful thought with them is, 'Is life worth living?' +but who ever heard such an expression from the lips of an active +entomologist? + +But I must have done with moralising and proceed to business. The +question is--How shall we set to work about the construction of a +collecting box? If it is to be a wooden one, select or make a box of +such a size as to suit your pocket or satchel, and cover the bottom, and +lid too if the depth allows of it, with sheet cork or slices of good +wine corks, about one-eighth of an inch thick, fixed on with glue. + +The metal box is not quite so easy, but even here you may save yourself +much work by keeping your eyes open. Very neat little collecting boxes +can be made out of the flat metal boxes in which are sold certain +favourite brands of tobacco. Some of these are just the right depth, and +also of a very convenient size for the coat pocket. Beg one of these +boxes from a smoking friend, and if the lid is not held by a hinge (a +great advantage, by the way), you can easily solder on a brass one. + +All that remains now is the fixing of the cork. Buy a sheet of cork at a +naturalist's shop, this being a commodity always in stock, and cut out +two pieces just the size to cover the bottom and the lid. + +Gum and glue are not very satisfactory as fixing agents, for, as you +will presently learn, there are times when it will be necessary to keep +the box moist, and moisture softens both these substances. The cork must +be fixed by means of little strips of metal. Here are two ways of doing +this: + +First.--Cut a few little strips of sheet tin, each about two inches long +and one-eighth wide. Double and bend them as shown in fig. 46, and +solder them to the surfaces which the cork is to cover (fig. 47). As the +cork is pushed in its place, these little slips are allowed to force +themselves through slits in it made by means of a penknife, and then the +ends are bent over as shown in fig. 48. Two or three such fasteners will +be quite sufficient to hold down each sheet of cork. + +[Illustration: FIG. 46.] + +[Illustration: FIG. 47.] + +[Illustration: FIG. 48.] + +[Illustration: FIG. 49.] + +Second.--Put the sheets of cork in their places _first_, then make a few +little slits through both metal and cork with the point of a penknife, +and then bind the two together with a few ordinary paper fasteners. This +arrangement is shown in section in fig. 49. + +Just one point more concerning the metal collecting box. You will often +call moisture to your aid in keeping the butterflies flexible and soft. +This will have but little action on zinc, but will sooner or later cause +the 'tin' (really tinned iron) box to rust. Here, then, is a point in +favour of zinc, but still a home-made 'tin' collector will last a long +time if kept dry when not in use. + +As already hinted, there are times when it is desirable to take home +certain butterflies alive, either for a study of their movements or for +the purpose of securing eggs for breeding. To this end you must provide +yourself either with a number of 'chip boxes' with a few small holes +pricked in the cover, or with some metal boxes with perforations for the +admission of air. If the latter, you will have no difficulty in +securing a few 'tin' boxes of suitable size, but, as the surface of the +metal is very smooth, you should always introduce a few leaves or +something else that will provide a foothold for the inmates. + +The last item of the outfit is the pins. Ordinary draper's pins are +quite out of the question. They are far too thick and clumsy for the +collector's work. If you are not already acquainted with the +'entomological pins,' you had better ask a dealer to give you a sample +card. This will be very useful for reference until you become well +acquainted with the various lengths, thicknesses, numbers and prices. +The card will contain one of each kind, with price and number attached. + +If you fix a butterfly with the ordinary pin, you may find the latter +partly covered over with verdigris after a time. This bright green +substance is formed by the action of decomposing animal matter on the +copper of the pin, and gives a very unsightly appearance to the +specimen. To avoid this the entomological pins are either silvered, +blackened or gilded. The silvered pins tarnish after a time, but the two +other kinds keep their colour well, and are therefore better. The gilded +ones are rather expensive and unnecessary, and perhaps the black ones +are to be preferred to the silvered, although they are rather more +costly. + +Most dealers will supply you with a box of mixed pins, each box +containing about six different sizes. This is very convenient for those +who work in a rather small way; but if you intend to make entomology a +prolonged study you had better get an ounce or so of each of the more +useful sizes. + +Butterflies vary much in size, and Nos. 3 to 8 are the most useful sizes +of pins to fix them; No. 3 being for the largest, and 8 for the +smallest. + +Supposing all the foregoing requisites to be quite ready, still you are +really by no means prepared for all your work. The butterflies captured +should be set as soon as possible after your return, and everything +required for _this_ part of the work must be in perfect trim. Yet I +think it will be more convenient just now to confine our attention to +the subject of 'Catching Butterflies,' leaving all the indoor work to +form the substance of another chapter. Our next point, then, shall be +the consideration of seasons, times, and localities. + +The earliest of the butterflies make their appearance on the wing in +April, or, if the weather is mild, towards the end of March; and from +this time you can find employment up to the end of September or the +beginning of October--a period of about seven months. But it must not be +supposed that all parts of this long season are equally prolific, and +will yield equally valuable catches. Remember the short term of a +butterfly's life, and bear in mind that each one has its own regular +season in which to spend the winged state; you will then see that anyone +who wishes to 'work' as many species as possible must arrange his +outings in accordance with the insects' own times. + +Some butterflies are double-brooded, and the two broods may not come +forth at certain fixed times. Hence they seem to be on the wing almost +without cessation for several months together, and therefore need not +have a special day set apart for them. But others are more uniform in +their date of appearance, and die off at about the same time. To catch +such as these you must be careful to watch the weather, make allowance +for any severities that may tend to cause a delay, or an unusually high +temperature that may hasten their emergence, and then select a day in +which you may expect to find them fresh and unworn. A week too early, +and none are to be seen; a week too late, and nearly all you catch are +worn and worthless. + +A glance at our Calendar (Appendix II) will give you a few illustrations +in point. Thus you will observe that May is a month for the 'Whites,' +early 'Blues' and certain of the Fritillaries; July for most of the +Hairstreaks and Browns, and so on. Before you have been long collecting +you will have captured the very common species, and then you will find +that your butterfly hunts are very unproductive unless you make it a +point to try for certain species at the proper times. + +Time, however, is not the only thing to take into account when preparing +for a day with the butterflies. It is equally important that we should +carefully select our locality in accordance with the known haunts of the +various species. As long as you are simply working up the common kinds, +you may wander almost at random in waste places, flowery meadows, corn +fields, railway banks, &c.; but when you have secured a few specimens of +each of these, you must search out the favoured resorts of the more +local and the rarer species. For instance, wooded spots must be visited +if you are to take certain of the Fritillaries, oak woods for the Purple +Emperor and the Purple Hairstreak, fenny districts for the beautiful +Swallow-tail, and so forth. In some cases the butterflies are closely +restricted to certain isolated localities, to which you must travel if +determined to obtain them. + +There yet remains another important matter to consider, and that is the +kind of day you shall select for your outing. Butterflies are not only +strictly day-fliers, but most of them venture out only on bright days. +Always choose as hot a day as possible, with a very bright sun. If you +are to be out for a full day's collecting, manage to be on the hunting +ground at about ten o'clock in the morning. As a rule there are not many +out before this time, and some do not appear to stir till an hour later: +still there are a few 'early birds' among them, one of which--the Wall +Butterfly--I have seen on the wing before eight. + +If your season, your day, and your locality are all well chosen, you may +reckon on a good six hours' work. At about four the butterflies begin to +lag, and then drop into their hiding places, one by one, till only a few +of the late stragglers remain on the wing. + +So far I have furnished some general instructions that may be regarded +as preparatory to the start; but I will now give a few hints as to the +mode of procedure when the day for field work has come. + +First, see that you have secured _all_ your apparatus, and that it is in +perfect condition. What is more annoying than to find, after you have +travelled some miles to get to your hunting ground, that you have left +your screw ferrule at home, or that the soldering of your metal Y is +just giving way? If you are troubled with a short memory, it will be +advisable to make out a list of every requisite for your field work, and +keep this for reference on all field days. + +Here is a list of your equipment for a day with the butterflies. Net, +ferrule or Y, stick, collecting box (the cork of which should be damped +if the box is a metal one), a few 'chip boxes' for live insects, killing +apparatus, a good supply of pins of several sizes, a piece of string, +needle and cotton, and your penknife. + +You observe in this list one or two items not previously mentioned, +since they hardly come under the category of apparatus, but a moment's +thought will convince you of their usefulness, especially in the case of +a breakdown. If your net catches in a thorn--a very common +occurrence--and a big rent is made, the needle and cotton will save you +a deal of agony, and perhaps loss of temper. If your stick breaks under +your exertions, the knife or the string may prove a most valuable +companion. Your pins may be stuck in the cork of your collecting box, +certainly the most convenient spot for immediate use; but you may also +have a reserve store in a small pocket cushion, or arranged neatly on a +strip of flannel which can be rolled up in the waistcoat pocket. + +At last you are on the hunting ground, fully equipped but inexperienced, +and at first find yourself just a little awkward in the use of your new +gear. Your experience with the cap has been a very wide one, and you are +possibly an expert at knocking down 'Whites' in the streets and in your +neighbour's kitchen gardens. Now you have to wield the net, and coax +your captives into your killing bottle; hence a slight feeling of +incompetence at first. + +You soon get over this, however, and within five minutes you may be seen +furiously slashing away at all the poor butterflies that come within +range, common 'Whites' and dingy 'Browns' receiving as much attention at +your hands as any rare gem that may happen to cross your path. + +How different are the movements of an experienced collector! He walks +stealthily along the route he has chosen, apparently taking but little +notice of the majority of butterflies that approach and pass him. He has +already secured his 'series' of nearly all the species, and is carefully +on the watch for the gems that are required to complete his cabinet. His +actions are slow and deliberate rather than rash; and he trusts more to +his eyes than his legs. + +The beginner may take to his field work quite to his own satisfaction, +and may travel homeward with a feeling of great pride over his first +day's catch; but yet there are a few points in which a little advice may +not be quite out of place, particularly so with regard to the management +of the net, and the killing and pinning of the insects. + +Most of the butterflies may be caught on the wing, and it is far better +to net them in the air than to sweep them off the herbage and flowers. +If these are rather low, you should strike the net smartly _upwards_ +from below them, but of course this movement is impossible with insects +that happen to be almost above your reach. If a butterfly is busily +engaged in searching out its sweet food, flying from flower to flower, +don't think of giving chase, but follow it up stealthily, and you will +sooner or later get an opportunity of striking at it while in the air. +Sometimes, however, you will see a powerful flier making a straight dash +across your field, taking no notice whatever of the fragrant blossoms, +but evidently engaged on some important errand. If such happens to be a +species you require, then you must run for it, but you will probably be +satisfied with only a few chases of this kind, particularly if the sun +is very hot, and the ground diversified with clumps of furze, heather, +'molehills,' and ditches. + +There are times when your only plan of netting a butterfly is to sweep +it from a flower or leaf on which it has settled. If the vegetation is +very low, you have simply to bring the net down upon it, and then, +holding up the apex of the net with the other hand so as to give it room +to fly, you can inclose it by grasping the lower part of the net as soon +as the butterfly has fluttered upward. If the herbage is tall it is +advisable to strike either upward or sideways at the insect, starting it +from the leaf or flower on which it rests; for if you bring _down_ the +net you will have to inclose the whole or part of the plant on which the +butterfly has settled--a procedure that often ends in a torn net, or in +the insect becoming damaged through being rubbed against the plant. + +Whenever you capture a butterfly by a sweep of the net through the air, +you immediately turn the ring into a horizontal position, so that the +bag of the net closes itself as it falls over the edge. This gives you +an opportunity of examining the insect before you introduce your killing +bottle. This is a very necessary precaution, for you are generally +unable to judge of the condition of a butterfly while on the wing, and +in some cases you cannot even be certain of the species. If, then, you +were to call the killing bottle into requisition for every capture you +make, you would certainly find yourself taking the life of many an +insect that is of no use whatever to you. Always examine your specimens +at the moment they have been secured, at least as far as it is possible +to do so, by looking through the gauze; and let your examination be as +brief as possible, or some of the butterflies that were at first in +splendid condition will render themselves useless to you during their +struggles to get away. + +When satisfied that an insect is likely to be of value to you, keep it +in the apex of the net by grasping the bag beneath it with the left +hand, and then introduce the opened killing bottle with the other hand. +As a rule you will experience not the slightest difficulty in coaxing it +into its trap, and then you quickly cover the mouth of the killing +bottle with the gauze, then apply your left hand, using it as a +temporary stopper for a few seconds, and now, the insect having been +quieted, replace the cork. + +A good killing bottle is almost instantaneous in its action, not only +stupefying, but immediately killing the insects; and as soon as you are +sure that each specimen is quite dead, you may pin it in your collecting +box. + +You must be cautious, however, on the one hand, that you do not take it +out too soon. If you do you may find that it recovers from the mere +stupefying effect of the poison, even after it has been pinned, and when +you open your collecting box for the next butterfly, you are horrified +at the sight of the poor victim struggling to free itself. + +On the other hand, don't keep the insects in the killing bottle too +long. If you do you will soon have a number, one lying on another, and +all tumbled about together while you are on the chase. Of course, under +such circumstances you are sure to damage them more or less. + +Many collectors, although they may always use a killing bottle for +moths, never employ one for butterflies, but kill them by pinching the +thorax. It is well to know how to do this, for it sometimes turns out to +be a really quicker process than that we have just been considering; +and, more than this, you can resort to it should you break or lose your +bottle while in the field. It is done in this manner: Bring the two +opposite sides of the net together, closing them on the insect so that +it cannot flutter. If now the wings are brought together over the back, +all is right, but if not, give it just a little room to flutter till you +have the opportunity of closing the gauze upon it with the wings in the +desired position. Now pinch the thorax smartly between the finger and +the thumb, applying the pressure outside the net, but be careful not to +squeeze the abdomen. In a moment you will find the insect quite dead, +and not in the least damaged unless you performed the operation +clumsily. + +Now as to pinning. Hold the dead butterfly between the finger and thumb +of the left hand, and pass a pin of convenient size through the centre +of the thorax above, and push it through so that the point appears +centrally on the under surface. It is now ready for your collecting box. + +So you work on till the sun begins to get low, and the butterflies +become fewer and fewer, till only a few stragglers of common species are +to be seen. Still there are a few hours of daylight and perhaps even of +bright sunshine before you, and if you are not weary with the work done, +you may very profitably spend these hours in the collection and study of +the habits of moths. + + +_Catching Moths by Day_ + +The reason for choosing the sunny hours for butterfly collecting is +obvious, all these lovers of brightness being then actively on the wing; +and although many may be driven out of their hiding places by beating +the herbage with the handle of your net, or even be searched out as they +rest on stalks and leaves during dull days or at morning and evening +twilight, yet such methods are comparatively tedious and unproductive. + +Some moths also are lovers of sunshine, and while engaged in butterfly +hunting you will often meet with a moth flying briskly from flower to +flower and taking its fill of both sweetness and brightness. Again, as +you wade among flowery herbs in quest of butterflies you will certainly +disturb a number of moths, causing them to take a short flight in search +of a safer spot. Thus you will almost invariably find a few moths among +the contents of your collecting box even though you made no special +effort to seek them out. But we shall now see how we may set to work to +obtain a successful catch of moths at times when butterflies are not so +much in demand, or during the less brilliant hours of the day, when +butterflies are at rest. + +The apparatus required for this work need not differ in any important +respect from that recommended for butterflies. The same net is used, any +reliable killing bottle will do, and the pins and collecting box used +for butterflies are equally serviceable. But your mode of procedure is +very different. + +As you walk towards your proposed hunting ground you will do well to +examine the trunks of trees, old walls, and wooden fences. In this way +you will meet with moths fast asleep, which are consequently easily +taken. All you have to do is to hold the open killing bottle obliquely +just below the insect, and then push it gently downward with a small +twig or stalk. As a rule the moth will drop direct into the bottle and +make no attempt to fly away; but some are very light sleepers, ready to +take flight at the slightest disturbance; and when dealing with these +you must be careful to bring the mouth of the killing bottle so closely +round them that there is no room for flight except into the bottle +itself. It is well, however, not to take long at this kind of searching, +but to reserve as much as possible of your time for what you consider to +be a very favourable locality. + +Speaking generally, a good locality for butterflies is a favourable one +also for moths, and you will do well to give special attention to +well-grown hedges, especially those that surround clover fields; also +overgrown banks, the borders of woods, open spaces in woods, the trunks +of isolated trees, gravel pits, and old chalk quarries. + +Walk beside or among the undergrowth of woods, or among the tall herbage +of waste places, tapping the branches and twigs with the handle of your +net as you go. Then, if your locality is well selected, you will rouse +moths to flight at almost every stroke. Some of these will shoot upward +among the lofty branches and disappear quite beyond your reach; others +will fly rather low and somewhat heavily, giving you favourable +opportunities to try your skill with the net; others, again, will fly +only a yard or so, and alight on a neighbouring leaf, often remaining so +quiet that the killing bottle is easily made to inclose them. + +There are moths that show a decided preference for large trees. These +may be seen hovering about high branches during the evening twilight, +and sometimes even in sunshine. In many such cases the chance of a +capture seems hopeless, but occasionally one will descend so low that a +watchful collector is able to secure it by a sweep of the net. + +If at any time you are in a locality by day where you suspect the +presence of certain species of moths at rest among the upper branches of +trees, such branches should be beaten if possible to dislodge the +insects they may shelter. A long stick will often serve this purpose +well, and, failing this, a few stones thrown among the branches may +prove effectual. In the case of small and rather slender trees, a kick +against the trunk will set the whole in vibration sufficient to surprise +all the lodgers; and the same effect may be produced with larger trees +by giving each a good sound blow with a mallet or some other suitable +implement. + +This or any other plan of 'beating' for moths is much more conveniently +worked by two collectors together than by one alone; for one engaged in +beating the herbage cannot be at the same time fully on the alert with +the net. If two persons are together, one may take the lead, armed with +the beating stick only, while the other, only very slightly in the rear, +is always ready to strike. + +We have said that butterflies should always be killed in the field, but +this plan is not so universally adopted with moths. Many collectors +carry a large supply of pill boxes when going out for the latter and +then take as many as they possibly can by boxing them direct in these. +This method of 'pill-boxing' is very simple in the case of the lazy and +soundly sleeping moths. It is only necessary to hold the open box below +the insect, and then cause it to fall by pressing the lid down gently on +it from above. + +Many of the moths so caught will remain quiet in the boxes and can be +taken home alive without much fear of damage. All may then be killed at +the same time by packing all the pill boxes in some vessel of sufficient +accommodation, and shutting them in with a little chloroform, ammonia, +benzole, or other suitable poison. The vapour will soon find its way +through the pores of the pill boxes, but, in order to make its action +speedy, each one should have a few perforations in the lid. + +Whatever advantages this method may give to the collector who works at +night, when the process of pinning would be more or less tedious, there +is no necessity for its adoption during the day. The large number of +pill boxes required is certainly far more bulky than the single +collecting box that would accommodate all the day's captures; and +although most of the insects boxed alive may be none the worse for the +shaking they get, and may not damage themselves by fluttering in their +small prisons, yet there is often a little loss on this score. + +If you do adopt the pill-boxing method, be very careful that you do not +mix the occupied boxes with the empties; and unless you fix on some +definite plan for the prevention of such an occurrence, you will often +find yourself releasing a prisoner from a box you have just opened to +receive a new-comer. + +Suppose that you start with all your empties in your right pocket. Then +each one, as soon as it is tenanted, might be placed in the _left_, with +the name of the insect, or any particular concerning it you would wish +to note, pencilled on the lid. + +When examining the trunks of trees you will be continually meeting with +specimens of very small Moths--_Pyralides_, _Crambi_, _Tortrices_, and +_Tineae_--and at first may find some difficulty in boxing or bottling +such small and delicate creatures. A grass stalk will enable you to tip +some of them into your killing bottle, but some are so snugly packed in +crevices of the bark that it is almost impossible to get them out +without damage, even with a thin and slender stalk. But a sudden puff of +wind from your mouth will often be sufficient to dislodge them and blow +them into your net, and from this they are easily transferred to a box +or bottle. + +These few hints will prove sufficient to start you on moth-hunting +expeditions during the daytime, and will enable you to make good use of +the dull days and cloudy hours when the butterflies are quiet; but we +must now turn our attention to the night work of the entomologist, and +see how we may attract and catch moths during their hours of work and +play. + + +_Searching for Moths at Night._ + +It is a well-known fact that the night-flying moths are attracted by +lights, a characteristic of these insects that it is difficult to +explain. Their love of darkness is in many instances so decided that +they absolutely refuse to take flight while the fading light of day +still lingers on the horizon, and even display a great aversion to the +rays of the moon; and yet these very same species will often rush madly +into the fierce glare of a naked artificial light, or fly with an energy +almost amounting to fury against the glass of a street lamp or lighted +window. + +Puzzling as this peculiar tendency is, we can profitably turn it to our +own account by making it a means of luring a number of moths into our +presence. + +The simplest way of putting this mode of capture into effect is to post +yourself at your open window, with net and cyanide bottle at hand, while +the brightest light you can command casts its rays as far and as wide as +possible into darkness outside. If you use an oil lamp for the purpose, +let it stand just inside the window frame, or, if a jointed gas bracket +happens to be situated beside the window, bend it round so that the rays +may pass over a wide area outside. + +Two such lights are sometimes a very decided advantage--one quite +outside the window to attract the moths from all possible points, and +then another near the middle of the room to invite them inside. Whether +you use either one or two lights, always see that it or they are so +surrounded by a screen that the moths cannot by any possibility rush +into the flame. There is nothing better for this purpose than a covering +of light gauze, for this is not only a barrier for the prevention of the +suicidal tendencies of the insects, but it also gives a good foothold to +those who would like to rest and enjoy the luminous feast. + +You will soon begin to learn that moths, like ourselves, exhibit great +differences in their ways of enjoying their festal moments. Some will +satisfy themselves by flying _near_ the light in almost a straight +course, hardly slackening their speed as they pass; or will, perhaps, +make a hurried curve round the light and then pass on at once about +other business. To catch these you must be always on the alert, with net +in hand, ready to make a dash at the right moment. But many will make +straight for the flame, and then, finding a barrier in the form of gauze +or glass, will either flutter round and round as if dissatisfied with +your attempt to save them from an untimely end, or else settle quietly +on the screen to enjoy the brightness for a long period. The flutterers +are usually easily covered by a glass or the open cyanide bottle, and as +for those that settle down quietly, you can take them at your leisure. + +It will not do for a collector to depend solely on this method of +obtaining moths, but at times when either his duties or the bad weather +keeps him at home it affords him a means of capturing a few specimens +that otherwise would have been missed. He may be even so busily engaged +in other matters that he cannot afford the time to stand and watch with +net in hand, but the insects that fly into his room and dance round the +gas jet or inquisitively examine the white surface of the ceiling are +easily netted or boxed without much loss of time. + +The chances of success at this kind of work will vary considerably with +the aspect, the season, and the weather. If your window opens on a large +flower or fruit garden, on a patch of wooded country with plenty of +underwood, a piece of waste ground overgrown with rank vegetation, or a +stretch of heath or moor, then you may expect a very large number of +visitors; but if you are situated on a level and barren country, or in +the dense atmosphere of a thickly populated district, you must not +reckon on many intruders. + +As regards the season, this is more extended than that of the +butterflies. A few species of moths may give you a call during the bleak +nights of October and November, and also during the somewhat less dismal +nights of February and March; but from April to September you may rely +on a goodly number of captures. Of course you will not expect many of +the 'rarities' and 'gems' to find you out; these are to be searched for +in the open field in the manner to be presently described; but your +lights will attract a large number of the commoner species of _Geometrae_ +and _Noctuae_, the former _chiefly_ during the early summer, and the +latter more or less throughout the season. + +A little experience will show you that the atmospheric conditions form a +very important consideration. The dark and warm nights are the most +productive. Very little luck is to be anticipated when the full moon is +throwing down her silvery rays from a clear sky; nor will you see many +while a cold east or north-east wind is blowing. Under these conditions +many moths prefer to keep in the sheltered nooks where they slept away +the sunny hours of the day. They love a warm and moist air such as calls +forth the odours of the fragrant blossoms that provide their sweets, and +show no dislike to a fine drizzling rain that you yourself would prefer +to avoid. A pelting shower will generally keep them under cover, but +they delight in the fresh and moist air that immediately succeeds the +passing storm. + +[Illustration: FIG. 50.--FRAME OF NET FOR COLLECTING INSECTS ON LAMPS +AND WINDOWS.] + +If you reside on the outskirts of a town an occasional tour of +inspection of street lamps may add a few specimens to your collection, +and some entomologists attach so much importance to the value of these +luminaries that they provide themselves with a special net for the +removal of moths from the glass and rails (fig. 50). The straight side +marked _a_ is applied to the panes of glass when flutterers or settlers +are to be taken, and the bend on the opposite side is to secure those +that rest on the rail. Such a frame is easily made by bending a piece of +stout wire to the required shape, and then soldering it to a ferrule to +receive a long stick. The net itself should not be deep. + +Many different forms of traps are now made for catching moths, and these +are deservedly coming rapidly into favour. They are generally +constructed on a 'catch-'em-alive-oh' principle, and have the advantage +that, after having been set, they may be left alone all night without +any watching, and give an ambitious collector the opportunity of taking +insects in his garden and searching in the open field both at the same +time. + +One of these traps may be constructed as follows at the cost of only a +few pence over the price of a small paraffin lamp. Put together a square +box, the sides about two feet and the front open, or procure a suitable +one from your grocer. Place a paraffin lamp with a bright tin reflector +at the back of this, and make a hole in the top just over the chimney to +allow the heated air to pass out freely. Three sheets of glass are now +to be placed as shown in the sketch (fig. 51), one upright piece +completely shutting off the lamp, and two others placed obliquely with a +space between them just large enough to allow admission. These must be +exactly the width of the box, and should not be permanently fixed, but +simply resting on small wooden supports nailed on to the sides. When +required for use, it is only necessary to light up the lamp, strew some +dead leaves on the bottom of the box, and put the sheets in their +places. It will be seen at once that the angles at which they are placed +will direct all light-seekers into the lower compartment, whence they +are not at all likely to find their way out again; and after vain +endeavours to reach the light they finally settle down on the sides of +the box or seek shelter among the dead leaves. + +[Illustration: FIG. 51.--A TRAP FOR CATCHING MOTHS.] + +Occasionally it happens that an entomologist is lucky enough to claim +the friendship of a person who, from the nature of his calling, is +peculiarly well qualified to render him great assistance. Thus a +friendly lamplighter, expert and patient in the use of the cyanide +bottle or pill box, is capable of giving valuable aid at times; and the +keeper of a lighthouse has it in his power to capture many a gem that is +seldom seen on the wing; but, although much may be done by means of +these and other stationary lights, this kind of work does not compare +favourably with the night rambles of a naturalist in the very haunts of +the objects of his search. + +For such out-door work in search of moths a good lantern is essential. +An ordinary 'bull's-eye' is almost useless, for, although it +concentrates a good light on certain objects, the narrow range of its +rays constitutes a strong objection to its use for entomological work. +For this purpose it is necessary that the rays of light not only pass in +front of you, but also shoot off right and left to warn you of the +approach of a moth before it is too late to wield the net. This wide +range may be obtained by means of three flat glass sides, or, better +still, by a bent plate glass front. + +In addition to this you must go out provided with your net, killing +bottle, and a number of pill boxes. Choose your night according to the +hints already given, and if you are on the look-out for any particular +species, be careful that the date of your outing is well timed, making +any necessary allowances for the forwardness or backwardness of the +season, for a moth that is generally due on a certain _average_ time of +the year may appear some weeks sooner if the preceding weeks have been +unusually warm, or its emergence may be delayed considerably by the +prevalence of cold east winds or a late frost. + +Make up your mind as to the field of your operations before you start, +and if possible choose a route that will carry you through a variety of +situations, so that you may pass the favourite haunts of a number of +different species. Clearings in woods with an abundant undergrowth, +waste places with plenty of tall and rank vegetation, overgrown railway +banks, clover fields, the flowery borders of corn fields, plantations in +parks, heaths and moors, sheltered and overgrown hollows such as chalk +pits and old disused quarries, reed and marsh land, all these are good +localities, each one inhabited by its own peculiar species, and if your +route runs through a fair variety of such places you may, other things +being equally favourable, depend on a good catch. + +See that your time also is well chosen. Of course you cannot say exactly +what the night will be till it actually comes, and, as you have to start +off before it is dark, you must consider the probabilities of the future +from the present condition of the air. Let it be a night when a bright +moon is not due, and if it follow a warm and moist day with a south or +south-west wind, or if drizzly, so much the better; but let your feet be +shod with boots that will permit you to wade through moist herbage +without danger, and take a waterproof if necessary. + +It is always advisable to be on your hunting ground before twilight sets +in, as a number of moths venture out before the sun has disappeared; and +then you can work on till midnight if you feel inclined, or even extend +your labours till the early hours of the morning. + +Before dusk you will meet with many of the little _Tortrices_ (page 298) +in sheltered spots, and a little later the _Geometrae_ and Hawks will be +on the wing. Thus, before dark, you may make good use of your net, +dealing with your captures just in the same way as recommended in the +case of butterflies. + +After a time, however, the lantern will have to be brought to your +assistance in making known the whereabouts of the later species, +consisting chiefly of the _Noctuae_, many of which do not make their +appearance till it is quite dark. If now you carry your lantern in your +left hand, your work will be rendered somewhat difficult and tedious, +for, although one hand is sufficient to manage the net properly, you are +compelled to rest your light on the ground every time you make a +capture, as it is impossible to box your specimens unless both hands are +quite free. This difficulty is easily overcome by suspending the lantern +by means of a string or strap placed round your neck, allowing it to +hang on your chest; and a further advantage is gained by having a second +strap round your chest to prevent it from swaying about with every +movement of your body. This arrangement gives you both hands perfectly +free during the whole time, and also prevents the necessity of +continually bringing yourself into a stooping or kneeling posture while +you are examining or boxing the specimens you have netted. + +There are now two courses open to you. Either you can kill and pin the +moths as you catch them, fixing each one securely in the collecting box, +or you may simply shut each one in a separate pill box and leave the +remainder of the work to be done at home. If the ordinary collecting box +only is used, a little of your time is necessarily occupied in pinning +and transferring, and if many insects are about such an occupation may +appear to you to be a waste of valuable time. But this is not all. Often +and often will you find that while thus engaged a splendid moth will +come and flutter round your light; and, before you have time to drop +your collecting box and pick up the net, the fine creature you would +have prized has darted off again. This certainly seems to speak in +favour of the pill-boxing method, but it must be remembered that a few +of the moths will continue to flutter after they have been boxed, so +that when you arrive home they are more or less damaged, a large number +of the scales that once adorned the wings now lying on the sides and +bottom of the boxes. Perhaps the best plan is to take both the +collecting box and also a quantity of pill boxes, and a little +experience will soon show you which is the better accommodation for +certain kinds. + +Particular attention must be paid to flowers, some of which are very +attractive to the _Noctuae_ especially. Sallow blossom in spring and ivy +bloom in autumn should be carefully and frequently watched, and at +other times the blossoms of heather, ragwort, bramble, clover, and +various other flowers must be searched. + +As you cast the rays of the lantern on the feasting moths some will +prove themselves very wary, and dart away at your approach; but others +will take but little notice of your advance, and will continue to suck +the sweet nectar, their eyes glaring like living sparks. + +As a rule the _Noctuae_ thus engaged are easily pill-boxed or caught +direct in the cyanide bottle; but a few of the more restless species are +to be made sure of only by a sweep of the net. Some will feign death as +soon as disturbed, and allow themselves to drop among the foliage, where +further search is generally fruitless. + +Another common difficulty arises from the inconvenient height of many of +the attractive blossoms--often so great that it is impossible to reach +them with the net, and very difficult to direct the rays of your lantern +on them. This is particularly the case with sallow and ivy, the flowers +of which are two rich sources of supply to the entomologist. + +[Illustration: FIG. 52.] + +[Illustration: FIG. 53.--NET AND LANTERN FOR TAKING MOTHS FROM HIGH +BLOSSOMS.] + +Those who intend giving special attention to these blossoms should be +provided with some form of apparatus that will enable them to extend +their operations as high as possible. Perhaps the most effective +arrangement is the well-known combination here figured. It consists of a +long and stout stick, at the top of which is a tubular joint (fig. 52) +that might be termed a T-piece were it not that the smaller part does +not stand out at right angles to the other. In this is fixed, in a +straight line with the stick, a short rod on which hangs a lantern--an +ordinary bull's-eye answers well here; and in the smaller tube is +another short rod carrying a shallow basin-shaped net, and of such a +length that the net is just in advance of the lantern. + +At first sight this arrangement will strike you as being very +unsatisfactory, there being no kind of trap to prevent the escape of the +insects. But it must be remembered that moths are more or less addicted +to habits of intemperance--that they will hold on to the supply of the +sweet fluid they enjoy till they are ready to drop with intoxication. +This being the case, some will fall into your net as soon as they are +startled by the sudden and near approach of the glare of your lamp, and +others are easily _made_ to fall therein by gently tapping the +flower-bearing stems from below with the edge of the ring. + +Having become acquainted with this very sad propensity, which thus +brings ruin to so many unfortunate moths, can we not yet further turn +their evil doings to our own profit in our endeavours to become +acquainted with their structure and history? Most certainly we can. All +we have to do is to distribute in their haunts a bountiful supply of +some artificial intoxicant such as they love, and then lie in wait for +the victims that fall a prey to our snare. This process is known to +entomologists as 'sugaring,' and is a splendid means of securing an +abundance of species, often including some rare ones that are scarcely +to be obtained by any other plan. Let us now inquire into the _modus +operandi_ of this interesting operation. + +The first thing to do is to prepare the luring sweetmeat. Supply +yourself with a quantity of strong, dark treacle, and also some dark +brown sugar; always remembering, in the selection of these viands, that +odour rather than purity is to be the guide. The best kinds of sugar are +those very dark and moist brands imported in a raw state from the West +Indies, nothing being better than that known as 'Jamaica Foots.' + +Mix about equal quantities of these with a little stale beer, and boil +and stir till all the sugar is dissolved. The consistency of the mixture +should be such that it will work well with a brush when used as a +paint--not too thick, nor so thin that it is easily absorbed by the +substance on which it is 'painted,' nor must it be in such a fluid +condition that it easily runs. + +When satisfied on these points, transfer the mixture to a tin canister, +see it properly covered, and set it aside as your 'stock' from which you +can draw supplies as required. Now secure an ordinary painter's brush of +convenient size, and a number of strips of linen or other rag, each one +of which is fastened to a hook formed of bent wire. These items, +together with the usual lantern, collecting box, pill boxes, and killing +bottle, complete your outfit for the sugaring expedition. + +When the selected time for operations has arrived, take sufficient +'sugar' for your night's work, mix it well with sufficient strong rum to +give it a very decided odour, and start off at dusk with this and the +other requisites just mentioned. + +The night chosen should be warm and calm, with a rather damp atmosphere, +and no moon preferred. Let your locality be a well-wooded one; +abounding, if possible, with giant oaks and other trees, and containing +open spaces with plenty of underwood and rank herbage. Such localities +are to be met with at their best in forest lands, and if you would do +wonders at sugaring you cannot do better than arrange for spending your +holidays in such a spot as the New Forest, taking with you sufficient +'sugar' for several nights' work. + +Having reached a likely spot of no very great extent, you prepare for +real work. Light up the lamp, and get out your sugaring tin and brush +ready for action. Take your course along some definite track that you +are sure to remember, painting vertical strips of sugar, about a foot +long, on the trunks of trees or on palings, and hanging strips of rag +that have just been steeped in the sugar on the branches of small trees +and shrubs where you do not find good surfaces for the brush. + +After satisfying yourself concerning the amount of sugar distributed, +retrace your steps, examining every patch of sugar as you go. It will +not be long before signs of life appear. Earwigs, spiders, centipedes +and slugs will soon search out the luscious feast, but unless the time +and the locality are ill chosen, the lantern will soon reveal a goodly +number of moths, with eyes glaring like little balls of fire, greedily +devouring the bounteous repast. These will consist chiefly of _Noctuae_, +but _Sphinges_, _Geometrae_ and numerous small species also join the +company. + +Some will exhibit a restless disposition, either darting off before you +make a close approach, or keeping their wings in rapid vibration as if +to be fully prepared for a hasty retreat when occasion demands. These +must receive your attention first; and, having secured them, proceed to +box as many as you require of the more lazy and gluttonous species. + +As a rule, moths thus engaged are easily pill-boxed, but the livelier +ones will not submit to such treatment without attempting to escape. The +best way to secure these is either to cover them with the opened cyanide +bottle (or its substitute), and replace the cork as soon as a favourable +opportunity occurs; or to perform the same feat with a glass-bottomed +pill box. + +The advantage of the latter over the ordinary boxes will be seen at +once. After the insect is covered, its movements can be watched, and so +a favourable opportunity can be seized for snapping on the lid. + +As already stated, some moths feign death when in danger, allowing +themselves to fall in places where they are often quite safe from +capture. Others allow themselves to fall simply because they have so +gorged themselves with the intoxicating sweet that they can no longer +maintain their hold. Both these classes of sugar seekers may easily be +secured by means of a net commonly known as the 'sugaring net.' + +[Illustration: FIG. 54.--FRAME FOR THE SUGARING NET.] + +This implement is so simple in its construction that anyone can easily +make his own. The frame may consist of two straight wires or canes fixed +in a metal Y, and the other ends joined by a piece of strong string or +catgut as shown in fig. 54. The net itself need not be deep. As soon as +you reach a tree where moths are feeding on the sugar, press the string +of the net against the bark just below them. The string at once assumes +the form of the trunk so well that you may be sure of every insect that +falls while you are boxing. + +For this work both hands must be free, and this is easily managed in +spite of the number of appliances called into service. The lantern is +slung round your neck and secured by a strap round the chest. The +'sugaring net' has a very short stick, and just while you are engaged in +boxing specimens, it may be gently held against the trunk by a slight +pressure of the body. But such precautions as these are necessary only +when the night worker is out alone. There are many circumstances, +however, that render the work of two or more in company much more +enjoyable than that of a single-handed entomologist. The labours are +considerably expedited where a division enables each one of the night +ramblers to take a particular portion of the work; and if there is such +a person as a nervous entomologist, that individual should on no account +go a sugaring in lonely spots on dark nights. Every rustling leaf gives +such a one a start; all footsteps are those of approaching disturbers of +the peace; and when at last the invisible landowner or his keeper, +attracted by the mysterious movements of the lamp, greets him with his +gruff 'What's your business here?' then for the moment he forgets his +enchanting hobby and wishes he were safely at home. + +It is certainly advisable to take a friend, whether an entomologist or +not, on such expeditions; and if you intend working on private grounds, +always make previous arrangements with the property owner, that you may +fear no foes and dread no surprises; for a sugarer is far more sure of +success in his work if he keeps a cool head and has nothing to think +about for the time being but his moths and his boxes. + +A few hours at this interesting employment pass away very rapidly, and +when midnight arrives there is often no great desire to leave off, +especially when it is known that some species of moths are not very busy +till very late at night. Still it is not advisable to surfeit oneself +with even the sweets of life. Perhaps it is better as a rule to work the +early species only on one night, and reserve another for the later ones. +The searchings are then always carried on with vigour throughout, and +the labours that are thus never made laborious ever retain their +attractiveness in the future. + +It has often been observed that, when sugaring has been carried on for a +few successive nights in the same locality, the success is greater each +night than on the one preceding it. Hence it is a common practice to +work a chosen 'run' for two, three, or more nights in succession; and +some collectors even go so far as to lay on the bait for a night or two +previous to starting work. For the same reason it is often advisable to +continue the use of a fairly productive beat rather than to wander in +search of a new one. + +In the neighbourhood of large towns one may often meet with patches of +sugared bark that mark the course and extent of a brother entomologist's +beat, and such are valuable to an inexperienced amateur in that they +give him some idea of the nature of the localities that are chosen by +more expert collectors. But it must be remembered that each entomologist +has a moral right to a run he has baited, and that it is considered +ungentlemanly, if not unjust, to take insects from sugar laid by +another. I have sometimes seen cards, bearing the names of the +collectors and the date of working, tacked on to baited trees and +fences, thus establishing their temporary exclusive rights to the use of +their runs. Such precautions are not necessary in large tracts of forest +land, where the choice of runs is practically unlimited. + +There are two other modes of capture available to the moth +collector--the use of decoy females, and the employment of 'sugar +traps'--and both these may be used on the sugaring run, or at other +times either in the woods or in your own garden. + +The wonderful acuteness of the sense by which the males of certain +species are enabled to seek out the females has already been alluded to, +and the possession of a suitable decoy will often bring you a number of +beautiful admirers without the least trouble, except that taken in +securing the decoy and preparing her temporary abode. It is absolutely +necessary that the female moth be one that has recently emerged, and +consequently you had better secure her in one of her earlier stages, +either by previous rearing or by collecting the pupae. + +A little cage composed of a framework of wire covered with gauze must +now be made. Perhaps the simplest pattern is that illustrated. Here the +gauze is attached to two wire rings, only a few inches in diameter, and +suspended by a string. Such a cage answers every purpose in the field, +and has the advantage of folding into an exceedingly small space when +not in use. It may be suspended in your garden or taken into the field +whenever you have a suitable decoy at your disposal. + +[Illustration: FIG. 55.--CAGE FOR DECOY FEMALES.] + +[Illustration: FIG. 56.--A SUGAR TRAP.] + +The sugar trap may be of much the same pattern as that in which a light +is used, but if intended for field work it should be of a convenient +size for portability. A lighter and far more convenient form may be +constructed as follows: + +Procure a large cylindrical tin box, and cut a circular piece of +perforated zinc just small enough to drop into it. Then make two wire +rings, one a _little larger_ than the top of the tin, and the other only +about an inch in diameter. Next make a conical net of leno, open at both +ends, and of such a size that the two rings may form the frames of its +two extremities. When the trap is required for use, cut a circular +piece of flannel or other absorbent, steep it in sugar that has just +been flavoured with rum, and place it in the bottom of the tin. Then +place a few pebbles of equal size around the sides to support the zinc +partition, drop in the partition, and then allow the net to hang on the +rim as shown in the sketch. + +This arrangement will explain itself. The moths, attracted by the sweet +perfume, flutter about in the net till at last they find their way +through the small ring. Once in, they make further attempts to reach the +sugar; and, at last, finding all efforts fruitless, and, like Paddy at +the fair, not being able to discover the 'entrance out,' they finally +settle down in a disappointed mood awaiting your pleasure. + +Perhaps another word of explanation is necessary here. Why not allow the +poor creatures to reach the sugar that attracted them to the spot? The +reason is this. They sometimes gorge themselves to such an extent that +their bodies, dilated to the fullest capacity with syrup, are a bit +troublesome when the insects are placed in the cabinet. It is therefore +advisable to see that the zinc is so far above the sugar that the moths +are unable to reach the latter by thrusting their extended proboscides +through the perforations. A few dead leaves scattered on the zinc is +also a useful addition, since it affords shelter to such of the insects +as prefer it. + +This is a very useful trap to keep in one's garden throughout the +season. It may not attract large numbers, but it has the advantage that +it requires no watching. It is simply necessary to set it at dusk, and +remove the captives in the morning or at your leisure. + + + + +CHAPTER VII + +_COLLECTING OVA, LARVAE, AND PUPAE_ + + +We have already observed that insects should, as a rule, be set as soon +as possible after their capture; and it would therefore seem that this +is the proper place for instructions in this part of the work. But it so +happens that butterflies and moths are to be obtained by means other +than those already described, and we shall therefore consider these +previous to the study of the various processes connected with the +setting and preserving of our specimens. + +Were we to confine our attention to the capture of the perfect forms +only, our knowledge of the _Lepidoptera_ would be scanty indeed, for we +should then be ignorant of the earlier stages of the creatures' lives, +and have no opportunity of witnessing the wonderful transformations +through which they have to pass. + +Such an imperfect acquaintance with butterflies and moths will, I hope, +not satisfy the readers of these pages; so it is intended, in the next +two chapters, to give a little assistance to those who would like to +know how to set to work at the collection of their eggs and larvae, how +to search for the pupae, and how to rear the insects from the stage at +which they are acquired till they finally emerge in the perfect form. + +These portions of an entomologist's work certainly take up a great deal +of his time, and also require much patience and perseverance; but the +advantages derived cannot be over-estimated, for in addition to the +knowledge gained of the early stages of insect life, this kind of work +will enable him to place in his cabinet a number of gems he would +otherwise have not and probably know not. Occasionally a prize may be +obtained in the form of a cluster of eggs (_ova_) of a rare species, in +many instances the larvae are to be obtained with comparative ease, while +the perfect insects of the same species are not often seen or not easily +captured, and many a rare pupa has been dug out of its hiding place +during a season when the entomologist had but little other work to +occupy his time. + +These and other similar subjects we shall now consider in turn. + + +_Collecting Ova_ + +The collection of ova may be carried on more or less throughout the +year. A number of moths are out in February, and even in January if the +weather is mild. These soon lay their eggs, which are hatched about the +time that the buds of the food plant are breaking. From this time till +late in the summer the ova of various species are being deposited, the +average period from laying to hatching being from two to three weeks. +Then, during the autumn, when the leaves of food plants are turning +brown and crisp, ova are still being laid, but these remain unchanged +till the new buds of the following spring are bursting. + +Of course if you intend searching for the ova of particular species you +must previously ascertain the favourite haunts of those species, become +acquainted with their food plants, and also with the season or seasons +during which the eggs are laid. But the few following hints will suffice +as general instructions for the search. + +In nearly all cases we must expect to find ova on the food plants of the +respective species, but at times, especially with certain moths, we may +come across them in the most unlikely spots. Thus, it sometimes happens +that a moth settles on a street lamp, and lays her eggs on the framework +round the glass, or even on the glass itself. The same thing may take +place on the sash or glass of a brightly lighted window. + +Such occurrences, however, we must regard as accidental and +comparatively rare, and therefore we confine our searchings for ova to +the food plants of the species we require. + +As a rule the under sides of the leaves will yield the most, but we have +already noticed (page 18) that some moths leave their eggs exposed on +the upper surface. Again, some larvae feed on flowers and seeds and +fruit, and the eggs of such are deposited on these parts. Those insects +which feed on the leaves of shrubs and trees often lay their eggs on +trunks, branches and twigs. Sometimes these are laid singly, sometimes +in dense clusters; and it is not unusual to find them arranged in rings +or spirals with great regularity. When examining the trunks of trees for +ova it is necessary to look well into the crevices of the bark, for some +insects take particular care to lay them in deep sheltered chinks; but +others take no such precautions, and deposit them on exposed ridges or +plain surfaces where they are easily discovered. + +One difficulty of the ova collector lies in the fact that many insects +lay on the upper branches of large trees. Of course a search for these +is out of the question; but in places where the trees have been cut down +a few years previously, and where a consequent undergrowth has +developed, there are considerable chances of success with these species. +Young saplings of trees often yield well, especially in places where +tall trees of the same species are absent. It may be mentioned, too, +that some moths (page 294) actually lay their eggs beneath the surface +of water, depositing them on the under surfaces of floating pond weeds; +and others (page 298) even enter the nests of wasps and bees for the +same purpose. It is clear, then, from these few remarks, that the work +of an ambitious collector of insects' eggs is by no means a monotonous +task; for his employment takes him into the meadows and woods, leads him +to the banks of ponds, and even compels him to tear down banks and +hedges for the nests of _Hymenoptera_ at the risk of a sting or two. + +One of the most productive sources of eggs is undoubtedly the possession +of captured females. When you are out netting butterflies you often see +a female that is evidently engaged in her matronly duties. Instead of +seeking food from the various flowers in her path, she pays attention +only to the foliage, looking out a suitable leaf on which to deposit her +eggs. Should you meet with an insect thus engaged which you would like +to rear at home, or of which you would like to know the egg, secure it +in a perforated pill box with a leaf of the proper plant; and it will +often supply you with abundance of eggs for your purpose, in many cases +depositing them in the box before you arrive home. The eggs of numerous +species of moths are also to be easily obtained from captured females. + +Some insects do not seem inclined to deposit their eggs in captivity as +freely as when at large, and in order to induce them to do so we must, +as far as possible, put them in their natural conditions. Let them have +plenty of room, and supply them with fresh twigs of their food plants, +kept green by standing them in vessels of water. It is also advisable, +supposing you are not well acquainted with the dispositions of the +species you have, to keep a portion of the box well shaded from direct +sunlight, and allow another part to be as bright as possible; for some +species will not lay in a bright light, while others will not do so +without it. + +Again, while some deposit their eggs within a few hours of quitting the +pupa case, others do not lay for several days. With regard to the +latter, it is frequently necessary to feed them while in captivity, by +placing in the box a piece of rag or sponge that has been dipped in +honey or syrup. + +Each batch of ova should be carefully examined with a view to knowing +them by sight on a future occasion. A sketch should be made in your note +book, showing every detail that you can make out with the aid of a good +lens. Then observations concerning the season, colour of the eggs, the +situation in which deposited, arrangement, and any other useful +particulars, should be entered. + +In the next chapter some hints will be given concerning the management +of ova and the rearing of the larvae from the time of hatching. + + +_Collecting Larvae_ + +This occupation is generally far more productive to the entomologist +than searching for ova. The latter are very small, usually well +concealed, and to be detected only by a careful scrutinising use of the +eyes; but the superior size of the larvae, the frequent bright colouring, +and the fact that they are easily beaten from their hold, render the +searchings of their hunters comparatively easy and fruitful. + +Before setting out on a larva-hunting expedition, there are a few +requisites to prepare. These include not only the implements for your +work in the field, but also the cages in which you intend to rear your +little captives. The latter are described a little later on under the +head 'Rearing Lepidoptera,' and the former we will now briefly +summarise. + +The outfit must consist of a quantity of suitable boxes, a stout hooked +stick, a strong net, and a white material to place under the herbage +while you are 'beating.' + +'Larva boxes' are usually made of zinc, and have little sliding doors in +the lids, so that the lids need not be removed while out of doors after +the fragment of the required food plant has been inserted. Such boxes +are not by any means essential. Small tin boxes will answer all purposes +nearly as well, providing a number of small holes be made in them for +the admission of air. Chip boxes are also fairly satisfactory, but these +also should be perforated. The best way to do this is to push a red-hot +iron wire through the chip, making about half a dozen small holes in +each box. This method will give you clean holes of a uniform size +without otherwise injuring the boxes. + +Metal boxes possess the advantage that they keep the food plants moist +for a long time, while chip boxes allow them to dry rather rapidly. Yet +there are some larvae that do far better in the latter, since such a +quantity of moisture exudes through their skins that they soon become +uncomfortably wet if their apartment is not well ventilated. Under these +circumstances perhaps it is better to take a supply of both, so that +changes may be made as found necessary. + +One grave objection to chip boxes, however, is the weakness of the +material. They are easily crushed by pressure, and a bottom or a top +disc of wood often falls out; but this is easily overcome by gluing +narrow strips of calico round the top and bottom edges. Chip boxes +should always be treated in this way, and they will then last five or +six times as long. + +Your supply of boxes should always include one large one of metal in +which to bring home a supply of food for the larvae. If you have a +botanist's vasculum, by all means take it, for nothing can serve this +purpose better. If not, any rather large square tin box will do, and +this may be carried in your satchel, or a couple of hooks may be +soldered to it so that a leather strap can be fixed for slinging it over +your shoulder. + +The net required is that commonly known as the 'sweep net.' It must be +very strong, for it has to submit to rather rough usage. The frame must +be made of thick wire; and the bag, which need not be more than a foot +deep, should be of strong calico or holland. + +Now with regard to the white material previously mentioned. This may be +a square of calico, hemmed round the edges. Nothing is more convenient +than this, as it occupies but little room in the pocket when not in use, +if neatly folded. The material need not be thick, but the larger it is +the better. Many prefer a white umbrella or an ordinary umbrella with a +white lining, but as this is only a matter of taste and convenience you +must decide for yourself as to which you will use. + +If your field of operations is only a little way from your head +quarters, and quantity of luggage therefore not a serious consideration, +you may provide yourself with a heavy mallet, loaded if necessary with a +pound or two of lead. This will prove very useful in shaking larvae from +trees and large branches. Lastly, take a pencil and a note book or +writing paper for your observations in the field. + +Now for the choice of the season. Larvae are to be found all the year +round. Early in the spring, as soon as the buds are bursting, some break +out of the eggs recently laid by the moths that appear in February and +March. Later on, during April and May, a host of both butterflies and +moths are busy arranging for their broods. Then, throughout the whole of +the summer, thousands of caterpillars of all sorts and sizes are to be +met with everywhere. And finally, during the bleak winter months, you +may amuse yourself by digging the hybernators out of their hiding places +where they rest themselves till the spring sun again calls them out to +refresh them with the young and tender leaves of a new year. Thus, +unless you are merely intending to search out certain species you happen +to require, there is not much difficulty in settling on the season. + +The day selected should be dry, for your work lies among the herbage of +banks, meadows, and woods, and nothing is more unpleasant than wading +through a wet and dense vegetation, or beating down on yourself a shower +of large drops from the branches of trees and shrubs. + +Having reached the hunting ground, the first thing to do is to look out +for _signs_ of the presence of larvae rather than for the larvae +themselves. Healthy vegetation with sound leaves must be passed by as +untenanted; but the presence of partly eaten foliage immediately arouses +suspicion. + +A little experience will soon enable you to distinguish between the +ravages of larvae and of slugs, snails, wasps, &c. Some of the smaller +larvae certainly eat out clean holes like those cut by _Hymenopterous_ +insects, but as a rule they bite away at the edges, leaving the midrib +and the larger veins standing out almost naked. + +By looking well into the edges of the eaten leaves, it is easy to see +whether the marauders have been recently at work. If they are dried up +and discoloured, it is not of much use to search; but if still green and +moist, you may feel almost sure that the hungry larvae are not far off. + +In this case you will carefully turn over the leaves to examine the +under sides, and also the leaf stalks and branches or stems; but you +must be prepared for all kinds of protective mimicry. Little green +caterpillars will be seen lying on the midrib or veins, so straight and +so still that they are scarcely perceptible. Others are snugly tucked in +a depression of a leaf with the same result. Then we must also be +prepared for the artful little tricks of the larvae of _Geometrae_ (p. +268), by which they imitate stalks and twigs so closely that a sharp eye +is necessary to discriminate between the two. + +While thus searching we may meet with the cast skin of a caterpillar. +This gives us fresh hopes, and so we continue our careful examination. +At last, on grasping a leaf in order to turn it over for inspection, we +feel something hairy or something soft and smooth. But lo! it is gone. +It is one of those numerous caterpillars that feign death and drop to +the ground on the slightest sign of danger. We search below for it, but +the density of the vegetation renders this hopeless, and we are just +about to start off in search of a more productive locality when we espy +a quantity of the excrement of larvae lying on a little bare patch of +ground close by. This gives us a new idea. Here is another indication of +the presence of the creatures we require, one that we can put into +practice; and by-and-by we learn that in many cases this is really the +surest sign of their whereabouts. + +We look at these little pellets of excrement, and gain at once some idea +of the _size_ of the larvae that produce them. Then we observe whether +they are fresh and moist, or dry and stale. If the latter, it is not of +much use to examine the leaves above; but if otherwise, there is little +doubt of our meeting with larvae, as the present position they occupy is +so truly marked. The leaves just over them are carefully examined, +either by turning them over as before described, or, if the height of +the foliage admits of it, by placing our heads below and looking upward. + +If we find that the larvae are some of those that endeavour to escape by +feigning death and allowing themselves to drop at the slightest +disturbance, the net is always kept beneath the leaves we are touching +in order to intercept them in their downward journey. + +Continuing the search, we meet with leaves that are rolled up and bound +with silk threads, and others that are drawn together and similarly +bound. These are carefully uncurled and pulled asunder with the result +that active little larvae are exposed to view, or, it may be, pupae are +discovered. In some cases flowers are drawn together in just the same +way, and an examination reveals one or more of the species that prefer +petals and other parts of flowers to the green leaves. + +Silken threads always arouse our suspicions. These may be seen lying on +the surfaces of leaves, and passing from one leaf to another, or they +may be hanging perpendicularly from the branches of trees above. In the +latter case a larva may be frequently seen on the lower extremity of the +fibre, swinging gently in the breeze, and, should we require it, we have +only to place the open box below for its reception. + +Hawthorn and other trees are sometimes seen almost devoid of leaves, +nearly every bit of green having been greedily devoured by a host of +small larvae. In such cases we often meet with dense clusters of silk +fibres that may easily be mistaken for spiders' nests. But when we look +more closely into the structure we observe that we have discovered +instead nests of gregarious larvae, such a large number being in each +little community that the deplorable appearance of the tree is at once +explained. + +A little farther on we meet with a sickly-looking plant in the midst of +a number of flourishing individuals of the same species, and stop to +make inquiries into the cause of this strange occurrence. Is it due to a +poorness of the soil? No, this cannot be the case; for intermingled with +its roots are those of its flourishing companions. We pluck a stunted +and half-shrivelled leaf and examine it. At first we do not notice the +cause of its peculiar condition; but, holding it up to the light, and +looking _through_ it, we see a number of little galleries that have been +eaten out of its internal soft substance, leaving the thin skin +(_epidermis_) almost entirely intact. But nothing more is to be seen. +Another leaf is examined in exactly the same way; and here we see the +little destroyer, lying motionless in its burrow till a gentle pressure +applied against it from outside causes it to wriggle along its narrow +passage. This is the larva of one of the little leaf miners mentioned +again on page 303. + +Reaching a little marshy spot we see a number of water-loving reeds, +most of them beautifully green and in a flourishing condition, but here +and there in their midst is a poor stunted specimen--another result of +the ravages of the larvae of one or more moths. An examination of the +blades reveals nothing; but on splitting open the stalk we discover some +larvae that have already devoured a quantity of the internal pith, and +thus endangered the life of the plant. On inspecting other similar reeds +we are at first puzzled as to how the larvae could get inside the stems +without damaging the outer portion; but at last we see in each one a +little discoloured hole that was eaten out by the young caterpillar +just after its escape from the egg. Once within the reed, it found a +plentiful supply of food, and there grew at the expense of the plant +without doing any further external damage save by causing a stunted +growth. + +It may be that the stem eaters we have found are just about full grown. +If so we examine a number of the stems with a hope that we may find one +or two that are just about to change to the chrysalis state, or even a +pupa already formed. By this means we may secure one of the perfect +insects without the necessity of feeding larvae at home. Such a +consideration becomes a most important one when it happens that the +required food plant is one that cannot be easily obtained. + +Close by the reeds is another water-loving plant in the form of an old +willow tree. This is always an attractive object to the entomologist, so +it comes in for a share of our inspection. On its leaves we may find +several species of the larvae of _Lepidoptera_, including those of some +of our largest insects. But a strange feature catches our eyes as we +happen to glance at the bark of the tree. Here we see a few holes of +different sizes, about which are a number of little fragments of wood +that remind us of 'sawdust;' and, examining the ground below, we see +quite a little heap of this dust, looking just as if a carpenter had +been at work on the spot. + +This is not the effect of a saw, however; it is a sure sign of the +ravages of wood-eating larvae (p. 224), whose powerful jaws gain them +admittance into the very hearts of trees, and the application of the +nose to one of the larger holes leaves no doubt of the presence of the +large and beautiful caterpillar of the Goat Moth (p. 224). + +If we require any of these wood-eaters, either for rearing or for +preservation, we must be prepared for a little rather heavy work. A +strong pocket knife is not sufficient, but with a good chisel the wood +can be gradually cut away, and the galleries traced, till at last we +come to the larvae snugly resting in their burrows. + +It often happens that the tree thus tenanted is half decayed, and +consequently the work is rendered much easier. Also, while tearing away +the wood, we often meet with a number of cocoons that have been +constructed by the caterpillars for their winter quarters, or as a +resting place while undergoing their transformations. These are composed +of the wood dust bound together by strong silk fibres, and are often in +such a good state of preservation that they form useful illustrations +for the cabinet. + +As further aids to larvae searching we may mention that many +species--chiefly of the _Noctuae_--hide under the surface of the ground +or among dense and low herbage during the day, and come out to feed only +by night; that many others feed on roots, and are therefore seldom seen +above the surface of the soil; also that a good number burrow into +fruits, in the interior of which they spend the whole of their larval +stage. The best way to secure the latter is to examine the 'windfalls' +that lie scattered on orchard lands, for it is a well-known fact that +the fruits that are infested with larvae generally fall earlier than +others--a result that must be attributed to the damaging work of the +larvae themselves. + +All the larvae collected should be carefully boxed at once, a separate +compartment being used for each species, and a few fragments of the food +plant being introduced in each case. It is also a good plan to have each +box previously lined with moss as a further addition to the comfort of +the captives. Without such a precaution some of the more delicate +species are liable to injury during their transmission from field to +home. + +Hitherto we have obtained our larvae by _searching_ only, but there are +times and occasions when our boxes may be far more rapidly filled by +methods that are not such a tax on our time and patience. Suppose, for +instance, that we reach a bush, the mutilated leaves of which seem to +show that larvae are present on its branches. We spread our white cloth +or open out the white-lined umbrella just under a selected branch, and +then tap that branch very smartly with our stick. + +Down comes a host of living creatures! Spiders, larvae, beetles, aphides, +earwigs, and what not, struggling and running about on our white fabric +in all directions, and all mingled with bits of stick, leaves, and +fragments of all kinds. We leave the cloth or the umbrella, as the case +may be, quite still for a few seconds to allow all the living creatures +to get a good foothold, and then, raising it into a vertical position, +allow all the rubbish to drop off. + +We can now put the cloth down again, and select as many of the larvae as +we require, giving our first attention to the nimble runners and loopers +that are already near the edge and just on the point of making their +escape. This productive method of larva hunting is known as 'beating,' +and is particularly applicable to tall herbs and the lower branches of +trees and shrubs. + +The same principle may be employed in the case of branches that are +quite out of the reach of the stick, but the blows are here applied to +the trunk, a mallet or some other rather heavy implement taking the +place of the stick. + +Another splendid method of securing larvae where mere searching would be +tedious and unproductive, lies in the use of the sweep net described on +page 102. This implement comes into service in waste places that are +covered with rank vegetation, in clover and hayfields, and in all spots +covered with low herbs. + +Walking among the vegetation, the net is swept right and left before +you, and the contents examined at frequent intervals. It is advisable to +work the different species of herbs separately as far as possible, +otherwise there may be some difficulty in the determination of the food +plants of the mixed larvae that the net will contain. If, however, this +plan is impracticable, you may save time by turning out all the +'sweepings' into one large box, leaving the sorting to be done at home +in leisure hours. + + +_Collecting Pupae_ + +We have seen that ova and larvae may be obtained in greater or less +abundance at all times of the year, so variable are the seasons of the +different butterflies and moths. The same remark applies equally well to +pupae; but so many of the Lepidoptera spend the winter months in the +chrysalis state that this period may be regarded as the harvest time of +the pupa hunter. + +A large number of caterpillars undergo their change to the quiescent +state during the months of August and September, and, of course, remain +in this state until the warm days of the following spring or summer. And +as insects even in the pupal stage have a number of enemies and dangers +to contend with, it is advisable to start your search for them as soon +as possible after they have changed. + +If you set your mind on searching for particular species, you should +endeavour to ascertain the _usual_ time at which such species pupate; +make any necessary allowances for the forwardness or backwardness of the +season, and then allow a week or two for the change to be completed, for +insects should never be disturbed at times when their metamorphoses are +in progress. + +For general pupa hunting the best season is undoubtedly from the end of +August to the end of October, but there is no reason why the work should +not be carried on throughout the winter. If, however, you continue your +work so late, you must not expect nearly as much success as time +advances. You must remember that entomologists are not the only pupa +hunters. Many hungry birds are always on the look-out for insects, and +seem to enjoy them equally well in all their stages. Those that +hybernate on or under the ground are liable to fall a prey to moles and +beetles. In addition to these dangers, all pupae are subject to the +effects of extreme cold, dampness, or floods. + +As regards the choice of a day, very little need be said. Any day that +is sufficiently genial for yourself will do for your work, except that +periods of hard frost render the ground too hard for digging--the most +profitable part of the pupa hunter's task. + +The apparatus required is extremely simple: A satchel or large pockets +full of small metal or chip boxes, a small garden trowel, and a strong +chisel. + +If metal boxes are used they should be perforated; in fact, nothing is +better than the ordinary larva boxes of the dealers. All the boxes, of +whatever kind, should be lined with moss previous to starting work. + +The trowel and chisel do not pack well with a number of small boxes, +therefore it is a good plan to fix them in a couple of leather sheaths +attached to your belt. In this position they are far more handy for use, +and the boxes are also in less danger of being crushed or damaged, as +they probably would be if in contact with hard and heavy tools. + +A note book is also a valuable addition to your outfit, as it enables +you to make memoranda concerning the trees and localities from which you +obtain your pupae. + +The best localities for pupa hunting are clearings in woods, parks with +numerous large timber trees, and meadows in which large isolated trees +are scattered; and the best trees include willows, poplars, oaks, +beeches, birches, elms, and hawthorns. + +The best thing you can do on arriving at the selected hunting ground is +to make at once for isolated trees of large size, and work each one as +follows: + +First examine well the crevices of the bark, for many caterpillars +descend the tree to within a short distance of the ground, and then seek +out a snug little crevice in which to spend the winter, often protecting +themselves with silken cocoons, or constructing a neat little shelter of +gnawed fragments of the wood cemented together. + +If there is any loose bark, very carefully force it out with your +chisel, and examine both its inner surface and the wood from which it +was removed. The wood thus exposed may reveal openings of the galleries +of wood-eating larvae, in which case, unless the material is too hard to +be broken up with the chisel, you may be able to trace out a few pupae. +Where these exist, they are usually to be found very near the entrance, +sometimes even protruding slightly from the opening, for the larvae +generally place themselves in this position of easy escape when about to +change. + +Next give your attention to the moss, if any, covering the lower portion +of the trunk. This affords a very favourite shelter to many species. +Tear it off very carefully, beginning at the top, and watch for loose +pupae and cocoons as you do so. Then hold the clumps you have removed +over a patch of bare ground or over a spread handkerchief, and pull it +to pieces, in order that any pupae it contains may fall out; also examine +the fragments carefully for others that may remain attached. + +This done, the surface of the ground must be examined. Remove all dead +leaves, and watch for pupae that may be sheltered beneath them. If any +loose stones lie on the ground, turn them over. Search well into the +angles between the roots, and if there are any holes or hollows beneath +them or in the trunk itself, pull out all loose matter within, and +_feel_ gently above and around for cocoons. + +After all loose matter has been removed, there still remains the soil +for examination. If this is very hard and clayey, it is probably useless +to carry the search any farther; also if very wet you need not expect +much; but if comparatively dry and friable there are more hopes of +success. + +As a general rule the north and east sides of the trunk are drier than +those which are exposed to the heavy rains brought by the south and +south-west winds, and are consequently more favoured by larvae that are +seeking a resting place for the winter. + +Most larvae seek shelter in the angles between the roots of the trees on +which they fed, but a few species seem to prefer the edges rather than +the corners; and in cases where no such angles are formed at the +surface, you will do well to examine the earth and turf all round the +trunk; but it is generally useless to extend the search more than a few +inches from the tree. + +After having searched every available nook and corner as far as possible +without digging, thrust the trowel obliquely into the soil a few inches +from the tree, turn over the sod, and then examine the spot from which +it was removed. Now give your attention to the sod itself. If loose and +friable, break it up gently, keeping a sharp eye for falling pupae, and +also for earthen cocoons that are easily mistaken for little lumps of +soil. + +If the soil is held together by roots, it must be pulled to pieces, and +the fragments shaken over a bare piece of ground where the fall of a +pupa or cocoon could be easily seen; and if you have removed a grassy +turf, it will be necessary to look between the bases of the blades as +well as among the roots. + +In this way you may search round tree after tree, wherever the soil is +of such a character as to allow of the admittance and shelter of larvae. +But the variability of your success will be quite beyond your +comprehension. Sometimes you will sight a grand old oak with the most +favourable anticipations, and consider yourself quite certain of a good +find when you discover, on a nearer approach, the liberal coating of +moss that clothes its trunk and the dry sandy soil at its foot; and yet +the most careful search ends in nothing but disappointment. At other +times you try your luck at tree after tree without ever seeing a single +pupa or even a cast-off case, and then, when just on the point of +despairing, you search round another that is apparently much less +promising, and, to your great surprise and delight, a dozen or two are +turned out in a few minutes. Such an occurrence as this is not at all +uncommon, and cannot be satisfactorily explained, but we must take +things as they come and make the best of them, remembering that pupa +searching is one of the best of all entomological operations wherewith +to test one's perseverance and patience. + +It may be mentioned, in conclusion, that the pupae of _Lepidoptera_ are +never to be found far below the surface of the soil. Generally they +exist, if buried at all, only an inch or two down, and very rarely at a +greater depth than four inches. + +In our next chapter we shall learn how to rear the perfect insects from +the earlier stages we have been considering. + + + + +CHAPTER VIII + +_REARING LEPIDOPTERA_ + + +_Management of Ova_ + +In the management of insects in all stages the strictest attention must +always be paid to one general rule on which the success of the work +almost entirely depends; and that is--keep every specimen as far as +possible under the same conditions as those in which you find it in +nature. + +Applying this principle to ova, we store them in airy and light places, +protected from the direct rays of the sun, and avoid handling and rough +treatment of any kind. It is also advisable in most cases to maintain a +slight amount of dampness corresponding with that of the open air at the +particular season of the year. + +They do not require much space, and it is certainly desirable not to +give much, otherwise the newly hatched larvae, when their time arrives, +will actively wander all round their premises in search of food, and +give you no end of trouble in gathering them up. + +Chip boxes are, as a rule, very good and very convenient receptacles for +ova. After placing the eggs in these, cover them over with very fine +muslin, held in place by elastic bands; and label each as far as you can +with the name of the species contained, and other particulars worth +remembering. The boxes may then be put in front of a window facing +north, or in any situation within or out of doors where rain and sun +cannot reach them. A greenhouse is an admirable place in which to keep +them, the natural dampness of the atmosphere being apparently a +considerable assistance to the tiny larvae just as they are striving to +escape from their shell. + +Whatever place is selected, it is absolutely necessary that the ova be +carefully watched, so that each brood may be supplied with the required +food plant within a few hours of quitting the shells. + +When ova are kept in a warm room, very great inconvenience and even loss +is sometimes caused by the appearance of larvae before the necessary food +plant shows its buds. Yet, on the other hand, it is sometimes a great +gain to the entomologist to get certain broods off early in the season, +providing the food is at hand; for in this way he can not only get some +of his work over during a slack season, but also, if he desires it, +secure an additional brood; that is, one brood more than the usual +number. Thus, supposing a certain species he is rearing is naturally +double-brooded, he can, by judicious management, secure three successive +broods before the food plant casts its last leaves. + +This hastening of the natural events of insect life is known as +_forcing_, and merely consists in subjecting the species concerned to a +reasonable amount of artificial heat, such as that of a room in which a +fire is always kept, or of a hothouse. + +It is interesting at all times to note the dates on which eggs are laid +or collected, and the times at which the young larvae appear. In addition +to this all changes that take place in the colours or forms of eggs +should be carefully observed; for such changes will assist you in +distinguishing between fertile and sterile ova, and also enable you to +judge approximately as to the date of the appearance of future broods. + + +_Rearing Larvae_ + +The main point in connection with the rearing of larvae is certainly the +selection and construction of the cages or their substitutes. For newly +hatched and all very small caterpillars a small bottle with a wide mouth +makes a very fair abode. Put a layer of sand or sifted soil in the +bottom, fix in this a small twig of the food plant or lay a few leaves +on the top, and then, after the larvae have been introduced, cover the +top with a piece of muslin, held in place by an elastic band. + +The great drawback with this arrangement is the lack of any provision +for keeping the food moist and fresh, thus rendering a change necessary +at very frequent intervals; but this may be obviated by using damp sand +as a foundation for the little twig of food plant. With this +improvement, if you cover the top of the bottle with apiece of glass, a +saucer, or any impermeable substance, you may keep the twig fresh for +several days, generally until the disappearance of the last leaf calls +for a fresh supply; but it is very doubtful whether the damp atmosphere +resulting from this inclosure is not injurious to the larvae. It +certainly does not seem to have much influence on some, but the +unhealthy conditions that result must be detrimental to the inmates. It +must also be remembered that many species require a _dry_ soil in which +to burrow when about to change. + +When the time comes for the change of food, great care must be taken not +to injure young and small larvae. In many cases they need never be +touched, for if a fresh twig be placed beside the stale one, they will +readily find their way to it; and to facilitate this, and also to afford +a convenient foothold to those larvae that accidentally fall from the +twig, the layer of sand at the bottom of the bottle should be covered +with moss or cocoa-nut fibre. + +[Illustration: FIG. 57.--A LARVA GLASS.] + +[Illustration: FIG. 58.--A LARVA GLASS.] + +If you find it necessary to move the larvae yourself from the stale food, +never touch them with your fingers, but lift them gently by means of a +small camel-hair brush. Larger larvae need never be moved at all. They +will always search out fresh food for themselves, and the stale may be +removed after they have quitted it. + +For rearing larger species ordinary bottles are hardly satisfactory, and +we must either use large jars or construct cages of some kind. + +An ordinary bell jar such as is used for covering ferns or for aquaria +makes a very useful 'larva glass.' Place a small bottle of water at the +bottom, and then introduce sufficient dry clean sand or sifted soil to +reach up to its neck. On the top of this place a layer of moss or +cocoa-nut fibre. Next introduce the food plant, fixing it firmly in the +bottle of water, and plugging up the space between the stem and the rim +with cotton wool. This precaution is to prevent the larvae from falling +into the water as they attempt to pass up or down the stem, and the wool +also helps to keep the twig in a vertical position. The glass is now +ready for the caterpillars, but it is advisable to keep a covering of +muslin or gauze over the top in all cases even though the larvae +contained are unable to creep up the surface of glass, for the great +enemies of caterpillars--the ichneumon flies--are always on the alert, +and will often take advantage of an open window to 'sting' the larva +rearer's pets. + +Another form of larva glass can easily be made out of a large glass jar +if you know how to cut off the bottom, or of a chemist's bell jar which +is open both at top and bottom. In this case the bottle of water and the +soil are arranged as before in a pan of unglazed earthenware, and then +covered over with the glass. This is shown in fig. 58, and is an +exceedingly convenient larva house, since the lifting of the glass +enables you to get at the insects without any trouble. + +[Illustration: FIG. 59.--A LARVA CAGE.] + +Wood larva cages are very commonly used for the larger species after +they have attained a fair size and require more food than can be stocked +in bottles and glasses. These cages have glass fronts, either sliding or +in the form of a hinged door, and sides of perforated zinc. They are +kept in stock by all dealers in entomologists' requisites, but equally +useful ones are easily constructed. If you select a box of suitable size +at the grocer's, cut out large pieces from the lid and sides with a fret +saw, and fix in the glass and zinc, you will have a cage that will +answer all purposes. + +The internal arrangements consist of a shallow tray filled with soil, in +which stands the bottle of water for the food, and a layer of moss +sufficiently high to cover the bottle completely. + +A series of such boxes standing on end on a shelf, or hanging on a wall, +will form a very satisfactory nursery for your pets, and will occupy but +little space. + +We have already observed that some larvae burrow into soil when about to +change, while others creep to a sheltered corner, or suspend themselves +from the food plant itself. It will be seen that the larva cage just +described supplies all these demands, and care must be taken not to +disturb the occupants while they are undergoing their metamorphoses. +Those that suspend themselves on the food plant should be allowed to +remain where they have fixed themselves, and when it is necessary to +remove the stale food in order to give a fresh supply to the later +larvae, let it be fixed in an airy place where it can be watched till the +perfect insects emerge. Those which suspend themselves on the sides or +top of the cage, or spin cocoons in the corners, should never be +disturbed unless you are greatly in want of the same cage for the +accommodation of another brood; and even then it is possible that their +presence will not in any way interfere with the new species. But if +their removal becomes a necessity, let it be carried out as carefully as +possible, and not until the change to the pupal stage is known to be +complete. + +The species that burrow into the soil or bury themselves in the moss +need never be disturbed till the rearing season is quite over, and then +they may be transferred to a box specially kept for the accommodation of +pupae. + +There is yet another method of rearing larvae to which we must refer--a +method known as 'sleeving'--particularly useful when you happen to have +the required food plants in your own garden. The ova or larvae are placed +on the plant, the whole or part of which is then covered with a bag or +'sleeve' of gauze. The larvae thus imprisoned have the full benefit of +fresh air and light, and are also free from the attacks of ichneumon +flies. They have a fair amount of liberty, and yet cannot get beyond +your reach; also abundance of fresh food without further trouble on the +part of the rearer. + +But even this arrangement is not perfection. It will not suit the night +feeders that like to hide beneath the soil during the day, and it +interferes somewhat with the burrowing tendencies of those which pupate +underground. These little difficulties, however, can be overcome by +placing the food plants in large pots or tubs of soil, and tying the +mouth of the 'sleeve' round the outside of this utensil. If this cannot +be done, those insects that pupate underground must be removed from the +plant when their restless disposition shows that the changing time has +arrived, and then be transferred to a box of soil where they can find +the seclusion they seek. + +The larvae that hybernate throughout the winter are rather more +troublesome, especially those which are inclined to take a ramble on +certain mild days in search of food when none is at hand. Still there is +no reason why even a beginner should not attempt the rearing of these. +They will require food in the autumn until the cold weather sets in, and +again early in spring as soon as the new leaves appear; but this is not +of much consequence to those who reside in districts where the required +food plants abound. + +Wood feeders also require some special treatment and precautions, and +the successful rearing of some is a matter of no little difficulty. A +wooden cage is, of course, quite out of the question with these, unless +you wish to test the power of their jaws. They must be kept in large +pots or jars, covered over with wire gauze or perforated zinc, and +supplied with fresh stems or logs of wood, or with moist sawdust fresh +from their favourite tree. A few of them--the 'Goat' (page 224), for +example--will eat dead and rotting wood, and may be fed on old palings +and other waste providing the right kind is selected. + +The troubles and disappointments of larva rearers are numerous and +varied, and commence with the earliest moments of the young insects. +Even the hatching period sometimes proves a trial, for it occasionally +happens that the young larva has not sufficient strength to bite its way +through the shell that surrounds it, and dies with nothing but the +surface of its head exposed to view. This may be the result of keeping +the ova in too dry a spot, the shell having become too hard and horny +for the little creature's jaws. + +Then the moulting seasons are always periods of trial to the larvae, and +often of loss to the rearer. Some of the hardier species may pass +through all their moults without appearing to suffer anything more than +a slight inconvenience at each, but in other cases the greater part of a +brood may fall victims to these ailments of the growing stage. + +Apart from these sources of loss, however, larvae are subject to numerous +diseases, infectious and otherwise, about which we know but little. A +fever may rage in one of our cages; a fungoid growth may establish +itself on the bodies of our pets, or we may see them cut down, one by +one, through a fatal attack of diarrh[oe]a. + +In many such cases we are at a loss as to what to do. Blue pills and +black draughts are not to be prescribed, and the modern practices of +surgery and inoculation have not yet been applied to insect patients +with very great success; but we must do our best to adopt hygienic +principles, paying the greatest attention to proper means of ventilation +and to a regular and wholesome dieting. In the case of diarrh[oe]a--a +very common insect malady--the best we can do is to avoid the young and +juicy leaves of the food plant, and substitute the older, and drier +foliage. + +Ichneumon flies have already been mentioned as great enemies of larvae. +These flies either deposit their eggs on the skins of caterpillars, or +thrust their sharp _ovipositors_ into the creature's flesh and lay their +eggs beneath the skin. When the young ichneumons are hatched, they +immediately begin to feed on the fatty matter that is usually stored in +comparative abundance under the skin of the caterpillar, and thus they +grow at the expense of their host, within whose body they lie completely +hidden from view. + +The poor caterpillar, though being eaten alive, often shows no external +signs of the mischief wrought within, and, even though its substance is +really decreased by the hungry internal parasites, yet the rapid growth +of these robbers maintains the general plumpness of a healthy larva. But +the ichneumons, having at last devoured the store of fat, and avoided +the vital organs of the caterpillar, as if with a view to preserve their +living home to the latest moment, now commence to attack the latter, +speedily reducing the vitality of their host to the lowest ebb, and +finally causing its death. + +This untimely end may come before the caterpillar is full grown, or the +insect may change to the pupa before the ichneumons have done their +worst, but it rarely occurs that the unfortunate creature has sufficient +strength to carry it on to the final stage. + +A large number of the collected larvae will have been 'stung,' much to +the disgust and disappointment of the rearer; and hence the advantage of +rearing your specimens from ova wherever possible, providing you keep +them so well under cover that the ichneumons cannot visit your broods. + + +_The Management of Pupae_ + +The disappointments connected with the rearing of _Lepidoptera_ are by +no means at an end when all have passed successfully into the pupal +condition, and the number of perfect insects obtained will often fall +far short of the number of pupae in your boxes; but we must now see what +can be done to minimise the death rate of the captives. + +One or more suitable boxes must be prepared for the reception of the +pupae, and the following suggestion will answer all purposes: + +Get a wooden box, quite rough and unplaned inside, large enough to +accommodate your pupae with ease, and not less than eight inches deep. +Make several holes in the bottom, or else knock the bottom completely +out, and nail in its place a sheet of perforated zinc. Also make a lid +consisting of gauze attached to a light wood frame. + +Place a layer of clean gravel, about an inch deep, in the bottom, and +over this a few inches of sifted soil or cocoa-nut fibre. + +Now take all the pupae that are 'earthed' in your cages, and arrange them +on the prepared bed; also add to them the pupae you may have dug out +during your various excursions. Cover all with a layer of the material +selected for the bed, and then add a layer of moss. + +Next come the pupae that are suspended by silky fibres, or are inclosed +in cocoons. These should be fixed with pins around the sides of the box, +running the pins either through the tuft of silk at the 'tail,' or the +outer layer of the cocoon, or through the portion of the dried food +plant to which they are attached. + +Here your pupae will remain till they emerge, and the box may be kept in +any airy place where it is not likely to be forgotten, for it is +essential that the perfect insects should be removed as soon as possible +after quitting their cases. It does not matter much whether the pupae be +kept in or out of doors, providing they are sheltered from rain and very +severe frosts; but of course, if the former, the imagines will emerge a +little earlier, even if the room in which your specimens are stored has +no fire. + +Even when protected in boxes such as that described the pupae are subject +to enemies and dangers. The soil and moss employed may contain slugs, +mites, or other creatures which prey on insects, and the amount of +moisture present in these materials and in the atmosphere may prove too +little for some species or too much for others. + +The remedy for the former evil is a simple one. Bake the soil or fibre +well before fitting up the box, and boil and afterwards dry the moss. +You may then be sure that all life previously contained is quite +destroyed. + +But the degree of humidity is a point not so easily settled, and so +variable are the experiences and opinions of different entomologists +that it is difficult to advise a beginner on the subject. The fact that +some strongly advise a perennial dampness, while others recommend no +attempt at the application of water, would seem to show that there are +probably important points to be urged on both sides. + +Nothing can be better than a very careful observation of pupae in their +natural conditions. When engaged in pupa digging you will observe that +the larger number are to be found on the east and north sides of trees +where the soil is protected from the heaviest rains; on the other hand a +good many are certainly found in very moist and sometimes even in wet +situations. + +Particular notice should be taken of such experiences, making every +allowance for the exceptions that prove the rule, and then let the +natural conditions be maintained in your nurseries at home. To carry +this out two pupa boxes should be kept, one for those species that seem +to require dry situations, and the other for the species that apparently +do best with moist surroundings. + +But when it is desired to maintain the pupae in a moist condition, great +care must be taken not to allow any accumulation of stagnant water. The +box we have described, with its bottom of perforated zinc, is well +adapted for this purpose. Let it stand on a couple of strips of wood, so +that any excess of moisture may readily drain through. The perforated +bottom will also allow of a free circulation of air, thus securing the +ventilation that is desirable in all boxes, whether wet or dry. + +If you have any insects that have pupated within moist stems, they +should be kept in a moist condition till they emerge. The simplest way +of doing this is to support the stems in a layer of wetted but +well-drained silver sand. + +Forcing may be resorted to when it is required to obtain the imagines +for early setting in order to get them in the cabinet before the busy +season begins. The method is simple. Place the pupa box on a shelf in a +room where a fire is kept every day. By this means you may get all your +specimens out within a few weeks, even when you start the forcing at the +beginning or middle of the winter. If, however, you require the imagines +for breeding, you must be careful that the eggs are not laid long before +the buds of the necessary food plants are due. + +When you are expecting the appearance of perfect insects, the pupa +boxes should be examined every day. A morning visit to your pupae (for +most insects emerge in the morning) may reward you with the sight of a +newly emerged imago, clinging to the rough surface of the box, thus +affording you an opportunity of observing the wonderful expansion of the +wings. But the greeting is not always of such a pleasant character, for +your disappointed eyes will sometimes be cast on a host of horrid +ichneumons that have just quitted a shell from which you were expecting +a prize of some specially valued species. + + + + +CHAPTER IX + +_SETTING AND PRESERVING_ + + +_Setting and Preserving Butterflies and Moths_ + +Up to the present we have been dealing only with living forms--learning +how to catch and rear the Lepidoptera that fall to our lot; but now we +have to become acquainted with the methods of preparing our dead +specimens in such a way that they may form a useful collection for +future study and reference. Our first attention shall be given to the +apparatus necessary for this work. + +The most important requirement is the setting boards, of which several +are necessary, the sizes varying according to the dimensions of the +different insects to be 'set.' The _lengths_ of all the boards should be +the same, not only for the convenience of packing when not in use, but +also in order that they may, if required, be arranged neatly in the +'drying house' to be presently described. The widths only will vary, and +in this respect the boards must be adapted to the measurements of the +insects from tip to tip when the wings are fully expanded. Thus, a set +of a dozen boards, ten or twelve inches long, and from one to five +inches wide, will do for a good start. Of course you may commence with a +smaller number than twelve, but if you really mean to do the thing well, +you will eventually require a good stock of boards. + +Here, again, it may be mentioned that all the necessary requisites may +be purchased ready for use, a set of boards and a drying house complete +costing from ten to twenty shillings according to size and quality; but +as the reader, like myself, may prefer to construct his own, I will +supply him with hints and suggestions sufficient for the work. + +Each board is constructed in this way. Cut out and plane up a piece of +wood of the required length and breadth, and about one-eighth of an inch +thick. Glue on the top of this a layer of cork about half an inch in +thickness, leaving the whole under a moderate pressure until the glue is +quite hard. The sheets of cork for this purpose may be bought at any +naturalist's stores; but slices cut from good large bottle corks may be +made to answer equally well if you don't mind the extra time expended in +cutting and fixing. + +When the glue has well set, trim off the edges of the cork flush with +the sides of the wood, and then cut out a groove down the whole length +of the cork, of course in the middle, and of such a size that it will +just contain the bodies of the insects for which it is intended. + +[Illustration: FIG. 60.--SECTION OF A SETTING BOARD.] + +The satisfactory cutting of this groove is not a very easy matter, but +if its position is first carefully marked, a long rat-tail file may be +made to plough it out neatly and regularly. As an alternative the +following plan is good. First cover the wood with a layer of cork about +a _quarter_ of an inch thick, and then glue on the top of this _two_ +narrower strips, about as thick as the bodies of the insects for which +the board is intended, leaving a space of the required size between +them, as shown in fig. 60. In this way you get a groove of square +section, that is in some respects preferable to the round one cut out by +means of the rat-tail file. + +[Illustration: FIG. 61.--SECTIONS OF SETTING BOARDS.] + +Now comes a question about which there is a difference in the tastes or +fancies of entomologists. Shall the boards be perfectly flat on the top, +or shall the sides slope from the groove, or shall the surface be +rounded? A glance at the three sections of setting boards will show +clearly what is meant. The rounded board is most commonly used, and the +graceful curve thus given to a butterfly or moth set on such is +certainly attractive; but it is not natural. The wings of these insects +are rigid, and are never seen bent into such curves in a living +specimen. For this reason I much prefer a perfectly plane surface on +each side of the groove. Then, as to whether there shall be a slope or +not, this is a matter of less importance. A very decided sloping of the +wings is certainly not so convenient for future examination; nor does +it, to my mind, look nearly so well as both sides in the same plane, or +at a very gentle inclination. But perhaps this subject had better be +left to the taste of the reader, remembering, however, that, whatever +plan be adopted, all the boards should be alike in this respect, so that +there may be a degree of uniformity in the cabinet. + +The surface of the cork must, in all cases, be nicely smoothed down with +glass paper, and then covered with thin white paper, fixed to its +surface with ordinary paste. + +When insects are on the boards, they should be placed in an airy spot, +as free as possible from dust, while they are drying. Hence the +advisability of some form of 'drying house.' This is simply a box, +standing on end, and provided with a hinged door consisting of a sheet +of perforated zinc in a wooden frame. The boards may slide in this on +little slips of wood nailed or glued on to the sides, or the wooden +bases of the boards may project beyond the cork at the ends, and slide +into grooves in the side of the house. + +[Illustration: FIG. 62.--A BUTTERFLY ON THE SETTING BOARD.] + +Beyond these requirements nothing is wanted save a good stock of pins, +thin card or ordinary writing paper, and a 'setting needle.' The +last-named item is simply a needle mounted in a handle, and a good one +may be made by thrusting the head of a darning needle into a piece of +twig. The pins used for setting--that is, for fixing the pieces of paper +or card to keep the parts in position--may be of the ordinary kind; but +entomological pins are far preferable, even for this purpose; for, being +much thinner, they do not damage and disfigure the setting boards so +much. + +Now as to the setting. First see that the pin with which you are to fix +your dead insect passes centrally through the thorax. Then fix it firmly +on the setting board, its body lying neatly in the groove of the cork. +Cut out some little pointed strips of card or paper, and, after bringing +the wings into position with the setting needle, fix each one by a +pinned strip. In spreading out the wings, care must be taken not to +pierce them at all, but simply to push them into their place by pressing +the needle at their bases, or by putting the needle beneath and +_lifting_ them out. + +Instead of pointed pieces of card, uniform strips of paper may be used, +as shown in fig. 63, each strip passing over both wings. + +After the four wings have been properly arranged, a few extra pins may +be used to keep other parts in position. Thus, the antennae may be placed +at equal angles, the proboscis may be extended, and a couple of pins may +be used to support the abdomen if it is inclined to bend downward. + +[Illustration: FIG. 63.--ANOTHER METHOD OF SETTING BUTTERFLIES AND +MOTHS.] + +As before mentioned, insects should be set soon after they are dead, +while the parts are still soft and supple. But where this cannot be +done, and the specimens have become stiff, brittle, and rigid, they must +be 'relaxed' before any attempt is made at setting them out. + +This process of relaxing consists in placing the specimens in a very +moist atmosphere for a few days. There are several simple ways of doing +this, many of which will readily suggest themselves to the reader. Your +collecting box, if a zinc one, may also be used as a relaxer. Pin your +stiff insects in it, after well moistening the cork, and simply shut +them up for a day or two. Any metal box will serve the same purpose +providing you put into it a piece of sheet cork on which to fix the +insects, and this cork may rest on a bed of moist sand. + +Another plan is to float the pinned specimens on corks in a shallow +vessel of water, and cover them over with a bell glass. + +Insects that are being relaxed should be examined from time to time, and +the degree of flexibility acquired tested by a gentle pressure of the +setting needle or by blowing on them. If not sufficiently supple, give +another day in the damp cell, but never allow them to be forgotten till +they are covered with mildew. + +The time occupied in thoroughly drying butterflies and moths will vary +considerably according to their sizes and the condition of the +atmosphere. In hot and dry summer weather four or five days will prove +quite sufficient for the _very_ small and thin-bodied species. From one +to two weeks, however, may be looked upon as the average period; but the +large and thick-bodied moths may require more than this. + +Perhaps the best test of their condition is the gentle pressing of the +setting needle against the abdomen--the last part of the body to become +dry and stiff. If the abdomen seems quite firm and rigid, you are pretty +safe in removing the specimen from the board; but if it bends at all +under a slight pressure of the needle let it remain for a day or two +longer. + +If your cabinet is quite ready for the reception of new-comers, the +insects may be put in their proper places immediately after their +removal from the setting boards; but if not, they may be pinned +temporarily in a 'store box' till the time comes when you have proper +accommodation provided. The full consideration of these matters will be +dealt with in another chapter. + +It is possible that the setting of some of your specimens will not +exactly please you. If such is the case, put them in a relaxing box for +a day or two, and then reset them more to your fancy. + +We have now to deal with a matter that applies more particularly to +moths, especially the very large and thick-bodied species. The abdomens +of these become more or less contracted and shrivelled on drying, +sometimes to such an extent as to look most unsightly. + +There is a remedy for this, and the time and patience required in +working it out will be well repaid by the superior results obtained. + +While the abdomen is still in a soft condition, make a slit throughout +its length with a very sharp knife or a sharp-pointed pair of scissors. +This slit should be made down the centre of the under surface, or, if +the insect is to be placed in the cabinet with the under side exposed, +down the middle line of the back. Then remove all the contents of the +abdomen, scraping them out with a piece of hooked wire, or removing them +with a fine pair of forceps, and leaving the skin as clean as possible +both within and without. Now introduce a packing of cotton wool, just +sufficient in quantity to maintain the natural form of the body as the +specimen dries. + +There is another good method of stuffing moths that possesses a decided +advantage over the one just described, since it leaves the specimen in +such a perfect condition that it shows no appearance of having been +stuffed when viewed from either side. This consists in snipping off the +abdomen at the waist, clearing out the contents with a hooked wire, +lightly stuffing it with cotton wool pushed in at the waist, and then +setting it aside to dry, while the other part of the insect is +undergoing the same process on the setting board. When both parts of the +moth are thoroughly dry, the stuffed abdomen is easily fixed in its +place with a little coaguline; and this, if neatly done, will not show +the slightest sign of the treatment to which the insect has been +submitted. + +Even after your insects are finally housed in the cabinet, they are +subject to two other dangers, both of which are more destructive to +moths than to butterflies. One is technically known as 'grease,' and the +other is the invasion of certain museum pests that feed on the +specimens, causing them to fall to pieces. + +Examine the moths that have been for a time in the cabinet, and some are +sure to exhibit an oily or greasy appearance, the hairs of the abdomen, +and perhaps also of the thorax, being clogged together just as if the +specimen had been dipped in oil, the same miserable condition perhaps +being shared also by parts of the wings. + +This is due to the gradual oozing out of the fatty matter that is always +present to a greater or less extent in the bodies of the insects, and +which must necessarily show itself more sparingly in specimens that have +been carefully stuffed. + +The old saying, 'Prevention is better than cure,' applies well in the +present case; but as there are times when a knowledge of the 'cure' is +the only means of saving a valuable specimen from destruction, we will +study both. + +To deal with the two in the order of the well-worn proverb, we will +consider the prevention first. Always carefully clean out and stuff the +abdomens of large-bodied insects; and as a rule, treat them with some +substance that will either absorb or dissolve out all oily matter. I +think the best plan is to remove the abdomen, clean it out if its size +permits of such an operation, and then, after labelling it to prevent +its future application to the wrong body, either let it remain in a +bottle of magnesia for several weeks, or soak it in benzole or ether for +a few hours or longer. + +If magnesia has been employed as an absorbent, you have simply to blow +or lightly brush off the loose powder that clings to the body, and then +fix it in its place with coaguline. A body dipped in ether or benzole +will look as if completely spoilt at first, for the furry coat that +clothes it will lie matted and almost entirely robbed of its beautiful +colours, reminding one forcibly of the proverbial 'drowned rat.' But +take no notice of this change. Let the body have at least a few hours in +the liquid, extending the time to a day or two in the case of very large +ones and those which experience has proved to be particularly liable to +'grease;' and, immediately on withdrawing it, fix it with a pin in a +good strong draught, such as you may obtain by opening a window about an +inch, or, if a breezy day, in the open air. + +These liquids are so volatile (and for that reason should never be left +exposed in an open vessel) that they rapidly evaporate, leaving the dry +hair to be loosened by the breeze, thus bringing back the natural +appearance almost perfectly. + +It is probable that many of the smaller insects that were not considered +to require the stuffing or grease-removing operations will sooner or +later exhibit a greasy tendency in the cabinet. At first the abdomen is +affected, and the oily matter then gradually creeps over the rest of the +body, finally spreading over the wings, and giving the insect a most +deplorable aspect. But these are not irreparably lost, and the following +cure will often bring them back to their former beauty. + +If the abdomen only shows signs of grease, cut it off and soak it in one +of the above-named liquids for a day or so, replacing it as above after +the drying operation. If, however, the oily matter has spread to the +thorax and the bases of the wings, the whole specimen must be soaked, +using a basin or jar of suitable size, covered with a plate of glass. A +good draught during the drying operation will do much to prevent the +hair from sticking in matted tufts close against the surface of the body +and wings, and a gentle brushing with a very soft camel-hair brush will +loosen and reset the fur. + +The other danger to which we have referred is the invasion of certain +'mites' and other museum pests that pay periodical visits to our cabinet +drawers and store boxes, often committing such havoc as to severely try +the patience of an interested naturalist. + +The way to prevent such intrusions is to make the atmosphere of the +compartments so obnoxious (to them) that they dare not enter; and, +further, to so spice up your specimens that they are no longer safely +edible to the invaders. + +The first object can be attained by always keeping camphor or +naphthaline (albo-carbon) in each division. A lump of either substance +may be secured by pins or a little perforated cell in the corner of each +drawer or box, or the bottom of each may be dusted with finely powdered +naphthaline; but as both these solids are volatile, care must be taken +to renew the supply as occasion requires. + +Then, with regard to the second precaution, perhaps nothing is more +effectual than corrosive sublimate. A little of this may be dissolved in +a small bottle of alcohol (spirits of wine), labelled with the name and +the word POISON, and kept ready for use. All the skins of stuffed +specimens should be painted with this solution, and the stuffing itself +may be moistened with it before insertion. + +There is yet another circumstance that renders a watchful care of your +cabinet specimens necessary, if you happen to possess many that were +captured 'at sugar.' Some of these will have so gorged themselves with +syrup that they are literally full of it, and this will sometimes find +its way to the outside, often dropping on the surface beneath. In such +cases the sugar should be removed as completely as possible, and the +bodies stuffed, before they are quite dry; but if the specimens have +been in the cabinet so long that they are stiff and hard, the under +sides of the abdomens may be completely cut out with a very sharp knife +and thrown away, and then the sugar cleaned out from the upper shell as +neatly as possible. + + + + +CHAPTER X + +_PRESERVING OVA, LARVAE AND PUPAE_ + + +Many young entomologists give their attention almost solely to the +perfect forms of insects, often collecting and studying a very large +number of species without regard to their earlier stages and +metamorphoses. This is decidedly a very great mistake. Although the +lifeless form pinned in a cabinet may be a most beautiful object in +itself, yet a study of this alone is uninteresting compared with that of +the wonderful changes it has undergone since the time it was a very +young larva. + +The different stages of the insects should be known as far as possible, +and these, as well as the perfect forms, should be included in the +collection for future study and reference. A good cabinet, according to +my own opinion, is one that possesses, among other good features, a +number of complete sets illustrative of the life history of at least the +more typical forms; and as it is not a difficult matter to preserve the +earlier stages, there is really no excuse for their omission from the +collection. + +The empty shells of ova are in themselves sometimes interesting objects, +especially when they illustrate some peculiar instinct on the part of +the parent. Sterile eggs, also, often fall into the hands of breeders +and rearers, and these, though in other respects unprofitable, are +useful in the cabinet. + +If fertile eggs are to be prepared for a collection, they must be +killed. This is easily done by thrusting into each one the point of a +very fine needle, or by immersing them for a moment in boiling water, or +by shutting them up in a bottle with camphor. In drying they often +contract more or less, and frequently change their colour; still these +are useful, providing notes have been taken of the characters thus lost. +The larger eggs are capable of special treatment where the owner has the +necessary time and patience, and where the highest results are desired. +By means of a surgeon's injector of small size the contents of the eggs +can be removed; and then, by the same instrument, a warm solution of +gelatine, coloured in such a way as to restore the natural tint, may be +forced into the empty shell. As the gelatine cools and hardens, it +prevents any shrinking of the shell, and thus both form and colour are +well preserved. + +For the preservation of larvae you will require one or two simple +appliances. + +The first of these is a suitable glass blowpipe, one form of which is +here illustrated. It consists of a glass tube, one end of which has been +drawn out very fine; a piece of watch spring tied to it in such a manner +that it will hold the skin of a larva at the small end, and a piece of +india-rubber tubing at the other end, pressed by means of a brass spring +clip. + +[Illustration: FIG. 64.--A BLOWPIPE FOR LARVAE.] + +A little drying oven is also very useful, but not absolutely necessary. +If you decide to have one, any square box of sheet iron (not soldered +tinned iron) may be readily converted into one. It must be provided with +a hinged door in the front with a ventilator at the bottom, a hole for +the escape of hot air at the top, and a tripod wire stand inside on +which to rest the specimens while drying. The whole should be supported +on a wire stand, so that heat may be applied below. + +Each larva to be preserved should be dealt with in this way. First kill +it by means of any one of the killing bottles or boxes already +described, or by immersion in spirit of wine. When quite dead, enlarge +the anal orifice by thrusting a needle into it, and then lay it on a +piece of blotting paper with its head toward you. Now take a round +ruler, previously covered with blotting paper, and roll the larva gently +from head to tail till all the contents of the skin have been expelled. +Next fix the skin on the fine end of the blowpipe, by thrusting the +point of the latter into the opening, and allowing the spring to press +gently on its edge. Gently blow into the skin till it is inflated just +to a _little below_ natural size, then either hold it near a fire or +rest it in the drying oven till it is quite dry and rigid. + +If you have done your work neatly, the skin and blowpipe will both be +quite air-tight when the clip is closed; and the air, finding no outlet, +will still further inflate the skin when it expands on exposure to heat. +This is the reason why you are directed to blow it out to something +short of the natural dimensions. If you find that this expansion causes +the skin to stretch beyond its normal size, a little of the air must be +allowed to escape while it is yet soft and flexible. + +The front of the larva is generally the last portion to become dry, and +when this is quite rigid the skin may be removed from the blowpipe. This +is a matter that requires the greatest care; for the skin is so very +thin and brittle that a little rough handling will break it to pieces. +As a rule it may be easily pushed off the pipe by a slight pressure +behind, or a gentle twisting motion will loosen its hold; but this +latter method can hardly be applied to hairy larvae without breaking off +the hairs, now rendered very brittle by the heat. + +If you find the slightest difficulty in detaching the skin of a valuable +specimen, it is far better to damage the blowpipe than to risk spoiling +the skin. Supposing your blowpipe is a glass one, you can easily break +off the end of it after making a cut with a very small triangular file, +and the portion thus removed may be left attached to the skin. Then, +after softening the glass blowpipe in a gas flame or the flame of a +spirit lamp, it can be drawn out thin again for future work. Those who +can manipulate glass tubing in this way will find it far better to lay +in a stock of suitable material, drawing it out when required, than to +purchase blowpipes ready made at the naturalist's shop. + +Very fine hollow stems, such as those of the bamboo cane, may be used +instead of glass; and these possess the advantage of being easily cut +with a sharp knife when there is any difficulty in removing the skin. +Again, whether glass or fine stems are used, a little grease of any kind +placed previously on the end will allow the dried skin to be slid off +with less difficulty. + +Preserved larvae should preferably be mounted on small twigs or +artificial imitations of the leaves of the proper food plants. A little +coaguline applied to the claspers will fix them very firmly on these +twigs or leaves, which are then secured in the cabinet by means of one +or two small pins. + +It is much to be regretted that the natural colours of many caterpillars +cannot be preserved in the blown skins. Some are rendered much lighter +in colour on account of the withdrawal of the contents, while others +turn dark during the drying. In the smooth-skinned species the natural +tints may be restored by painting or by staining with suitable aniline +dyes, but these artificial imitations of the natural colours are always +far less beautiful than the hues of the living larvae. + +Very few words need be said on the preservation of pupae. Many of them do +not alter much in form and colour, and therefore they require no special +preparation. + +If a pupa has to be killed for the purpose of adding to the value of the +collection, simply plunge it into boiling water, and it is ready to be +fixed in the cabinet as soon as it is quite dry. + +The empty pupa cases, too, from which the perfect insects have emerged, +are often worth preserving, especially if the damage done by the imago +on forcing its way out is repaired with the aid of a little coaguline. + +Let all larvae and pupae be preserved in their characteristic attitudes +and positions as far as possible, so that each one tells some +interesting feature of the life history of the living being it +represents. Further, enrich your collection by numerous specimens of the +various kinds of cocoons constructed by the larvae, pinning each one +beside its proper species; and never refuse a place to any object that +relates something of the life history of the creatures you are +studying. + + + + +CHAPTER XI + +_THE CABINET_--_ARRANGEMENT OF SPECIMENS_ + + +The selection of a cabinet or other storehouse for the rapidly +increasing specimens of insect forms is often a matter of no small +difficulty to a youthful entomologist. Indeed, there are very many +points of considerable importance to be considered before any final +decision is made. Freedom from dust, the exclusion of pests, the +convenience of the collector, the depth of his pocket, and the general +appearance of the storehouse must be considered, and it is impossible, +therefore, to describe a form that is equally suitable to all. + +If it is absolutely necessary that the cabinet (or its substitute) be of +a very inexpensive character, and if, at the same time, the collector +has not the mechanical skill necessary for its construction, then +perhaps the best thing he can do is to procure a number of shallow +(about an inch and a half deep) cardboard, glass-topped boxes, such as +are to be obtained at drapers' shops. For the sake of uniformity and +convenience in packing, have them all of one size. Glue in small slices +of cork just where the insects are to be pinned, and see that each box +is supplied with either camphor or naphthaline. All the boxes may be +packed in a cupboard or in a case made specially to contain them; and a +label on the front of each will enable you to select any one when +required without disturbing the others. + +It may be mentioned here that glass is not necessary, though it is +certainly convenient at times, especially when you are exhibiting your +specimens to admiring non-entomological friends, who have almost always +a most alarming way of bringing the tip of the first finger dangerously +near as they are pointing out their favourite colours. 'Isn't _that_ one +a beauty?' is a common remark, and therewith off snaps a wing of one of +your choicest insects. When glass is used, however, see that the +specimens are excluded from light, or the colours will soon lose their +natural brilliancy. + +Anyone who has a set of carpenter's tools and the ability to use them +well will be able to construct for himself either a set of store boxes +or a cabinet of many drawers in which to keep his natural treasures. In +this case a few considerations are necessary before deciding on the form +which the storehouse is to take. + +A cabinet, if nicely made, forms a very sightly article of furniture; +and, if space can be found for it, is the best and most convenient +receptacle. One of about twelve to twenty drawers will be quite +sufficient for a time; and the few following hints and suggestions may +be useful. + +The wood used should be well seasoned, and free from resin. The drawers +should fit well, and slide without the least danger of shaking. Each one +should be lined with sheet cork, about one-eighth of an inch thick, +glued to the bottom, nicely levelled with sand paper, and then covered +with thin, pure white paper, laid on with thin paste. It is also +advisable to cover each with glass, inclosed in a light wood frame that +fits so closely as to prevent the intrusion of mites. + +The drawers may be arranged in a single vertical tier if the cabinet is +to stand on the floor, or in two tiers if it is to be shorter for +placing on the top of another piece of furniture; and glass doors, +fastened by a lock and key, may be made to cover the front if such are +desired as a matter of fancy, or as a precaution against the meddlesome +habits of juvenile fingers. + +Store boxes are sometimes chosen in preference to cabinets because they +are more portable, and because they can be arranged on shelves--an +important consideration when floor space is not available. + +These boxes should be cork-lined and glazed like the cabinet drawers; +and if they are made in two equal portions, lined with cork on both +sides, and closing up like a book, they may be arranged on shelves like +books, in which position they will collect but little dust. + +Both store boxes and cabinets are always kept in stock by the dealers, +the former ranging from a few shillings each, and the latter from +fifteen shillings to a guinea per drawer. Knowing this, you can decide +for yourself between the two alternatives--making and purchasing. + +We have now to consider the manner in which our specimens should be +arranged and labelled. + +The table forming Appendix I contains the names of _all_ the British +butterflies and larger moths, and shows their division into _Sections_, +_Tribes_, _Families_, and _Genera_. This table is the result of most +careful study on the part of leading entomologists, and shows how, in +their opinion, the insects can best be arranged to show their relation +to one another; and you cannot do better than adopt the same order in +your collection. + + RHOPALOCERA + PAPILIONIDAE _Euchlo[:e]_ NYMPHALIDAE + _Papilio_ O O O _Argynnis_ + O O O O O + O O O O O + O O O O O + Machaon Rapae Cardamines Edusa O + Selene + PIERIDAE O _Leucophasia_ O + _Aporia_ O O O O + O O O v.

These, when cut up, supply you with neat labels for your +specimens. + +If you intend to study the British _Lepidoptera_ as completely as +possible, you may as well start at once with a sufficiently extensive +cabinet, and arrange all the labels of your list before you introduce +the insects. You will thus have a place provided ready for each specimen +as you acquire it, and the introduction of species obtained later on +will not compel you to be continually moving and rearranging the +drawers. + +Probably the number of blank spaces will at first suggest an almost +hopeless task, but a few years of careful searching and rearing will +give you heart to continue your interesting work. + +Arrange all the insects in perpendicular rows. Put the names of each +section, tribe, family, and genus _at the head_ of their respective +divisions, and the names of the species below each insect or series of +insects. The opposite plan, in which the circles represent the insects +themselves, will make this clear. + +Three or four specimens of each species are generally sufficient, except +where variations in colouring are to be exhibited. Wherever differences +exist in the form or markings of the sexes, both should appear; and one +specimen of each species should be pinned so as to exhibit the under +side. + +Finally, each drawer or box should have a neat label _outside_ giving +the name or names of the divisions of insects that are represented +within. This will enable you to find anything you may require without +the necessity of opening drawer after drawer or box after box. + + + + +PART III + +BRITISH BUTTERFLIES + + +We have now treated in detail of the changes through which butterflies +and moths have to pass, and have studied the methods by which we may +obtain and preserve the insects in their different stages. I shall now +give such a brief description of individual species as will enable the +reader to recognise them readily. We will begin with the butterflies. + + + + +CHAPTER XII + +_THE SWALLOW-TAIL AND THE 'WHITES'_ + + +Family--PAPILIONIDAE + +_The Swallow-tail_ (_Papilio Machaon_) + +Our first family (_Papilionidae_) contains only one British species--the +beautiful Swallow-tail (_Papilio Machaon_), distinguished at once from +all other British butterflies by its superior size and the 'tails' +projecting from the hind margin of the hind wings. + +This beautiful insect is figured on Plate I, where its bold black +markings on a yellow ground are so conspicuous as to render a written +description superfluous. Attention may be called, however, to the yellow +scales that dot the dark bands and blotches, making them look as if they +had been powdered; also to the blue clouds that relieve the black bands +of the hind wings, and the round reddish orange spot at the anal angle +of each of the same wings. + +It appears that this butterfly was once widely distributed throughout +England, having been recorded as common in various counties, and has +also been taken in Scotland and Ireland; but it is now almost +exclusively confined to the fens of Cambridgeshire, Huntingdonshire, +and Norfolk. Occasionally we hear of the capture of single specimens +quite outside these localities, sometimes even in most unlikely spots, +where its food plant does not abound. But we know that _Machaon_ is a +general favourite with entomologists, and that it is sent in the pupal +state, by post, to all parts of the kingdom; so that the occasional +capture of the insect far beyond the borders of its haunts is probably +the outcome of an escape from prison, or of the tender-heartedness of +some lover of nature who could not bear to see such a beautiful creature +deprived of its short but joyous, sunny flight. + +You cannot hope to see this splendid butterfly on the wing unless you +visit its haunts during its season--May to August; but the pupae may be +purchased for a few pence each from most of the entomological dealers; +and if you obtain a few of these and watch them closely, you may be +fortunate enough to see the perfect insect emerge from its case, and +witness the gradual expansion of its beautiful wings. + +The pupa (Plate VIII, fig. 7) itself is a most beautiful object. Its +colour is a pale green, and it is fixed to its support by the tail, and +further secured by a very strong silk band. + +The larva (Plate VIII, fig. 1), too, is exceedingly beautiful. Its +ground colour is a lovely green, and twelve velvety black rings mark the +divisions between the segments. Between these are also black bars, all +spotted with bright orange except the one on the second segment. + +A remarkable feature of this larva is the possession of a forked, +Y-shaped 'horn,' that is projected from the back, just behind the head, +when the creature is alarmed. If it is gently pressed or irritated in +any way, this horn is thrust out just as if it were an important weapon +of defence. And perhaps it is, for it is the source of a powerful odour +of fennel--one of the food plants of the caterpillar--that may possibly +prove objectionable to some of its numerous enemies. + +The food plants of _Machaon_ are the milk parsley or hog's fennel +(_Peucedanum palustre_), cow-parsnip (_Heracleum sphondylium_), and the +wild angelica (_Angelica sylvestris_); but in confinement it will also +partake of rue and carrot leaves. + +The caterpillar of this species may be found in the fens during the +greater part of the summer. It turns to a chrysalis in the autumn, and +remains in this state throughout the winter, attached to the stems of +reeds in the vicinity of its food plants. The perfect insect is first +seen in May, and is more or less abundant from this time to the month of +August. + + +Family--PIERIDAE + +This family, though known commonly as the 'Whites,' contains four +British species that display beautiful tints of bright yellow or orange. + +In many respects the _Pieridae_ resemble the last species. Thus the +perfect insects have six fully developed legs; the caterpillars are +devoid of bristles or spines; and the chrysalides are attached by means +of silky webs at the 'tails,' and strong cords of the same material +round the middle. + +All the larvae are also cylindrical or wormlike in shape; and their skins +are either quite smooth, or are covered with very short and fine hairs, +that sometimes impart a soft, velvety appearance. + +The members of this family are remarkable for their partiality for +certain of our cultivated plants and trees; and are, in some cases, so +abundant and so voracious, that they are exceedingly destructive to +certain crops. + + +_The Black-veined White_ (_Aporia Crataegi_) + +This butterfly may now be regarded as one of our rarities. At one time +it was rather abundant in certain localities in England, among which may +be mentioned the neighbourhoods of Cardiff and Stroud, also parts of +Kent, Sussex, Hampshire, Huntingdonshire, and the Isle of Thanet; but it +is to be feared that this species is nearly or quite extinct in this +country. It is well, however, not to give up the search for it, and if +you happen to be in one of its favoured localities of former days, you +might net all the doubtful 'Whites' of large size that arouse your +suspicions, liberating them again if, on inspection, they do not answer +to the description of the species 'wanted.' This course becomes +absolutely necessary, since the Black-veined White is hardly to be +distinguished from the Common Large White while on the wing. + +If you examine a number of British butterflies you will observe that in +nearly all species the wings are bordered by a fringe of hair, more or +less distinct. But the case is different with _Crataegi_. Here they are +bordered by a black nervure, without any trace of fringe, thus giving an +amount of rigidity to the edges (see Plate I, fig. 2). + +The wing rays, or nervures, are very distinct--a feature that gave rise +to the popular name of the butterfly. In the male they are quite or +nearly black, but those of the fore wings of the female are decidedly +brown in colour. At the terminations of the wing rays there are +triangular patches of dark scales, the bases of which unite on the outer +margins of the wings. + +Another peculiar feature of this insect is the scanty distribution of +scales on the wings. This is particularly so in the case of the female, +whose wings are semi-transparent in consequence. + +The butterfly is on the wing during June and July, at which time its +eggs are laid on the hawthorn (_Crataegus Oxyacantha_) or on fruit +trees--apple, pear and plum. + +A vigorous search of these trees in the proper localities _may_ reveal +to you a nest of the gregarious larvae, all resting under the cover of a +common web of silk. These remain thus under their silken tent throughout +the hottest hours of the day, and venture out to feed only during the +early morning and in the evening. + +When the leaves begin to fall in the autumn, they construct a more +substantial web to protect themselves from the dangers of the winter, +and in this they hybernate till the buds burst in the following spring. +They now venture out, at first during the mildest days only, and feed +voraciously on the young leaves, returning to their homes to rest. Soon, +however, they gradually lose their social tendencies, till at last, when +about half or three-quarters fed, they become quite solitary in their +habits. + +In May they are fully grown, and change to the chrysalis state on the +twigs of their food trees. + +The larva is black above, with two reddish stripes. The sides and under +surface are grey, the former being relieved by black spiracles. + +The pupa (page 45) is greenish or yellowish white, striped with bright +yellow, and spotted with black. + +It is probable that the reader will never meet with this insect in any +of its stages. But, though it may have left us, it is still very +abundant on the Continent, where it does great damage to fruit trees; +and the foreign pupae may be purchased of English dealers. + + +_The Large White_ (_Pieris Brassicae_) + +We pass now from one of the rarest to one of the most abundant of +British butterflies. Everybody has seen the 'Large White,' though we +doubt whether everybody knows that this insect is not of the same +species as the two other very common 'Whites.' The three--Large, Small, +and Green-veined--are so much alike in general colour and markings, and +so similar in their habits and in the selection of their food plants, +that the non-entomological, not knowing that insects do not grow in +their perfect state, may perhaps regard the larger and the smaller as +older and younger members of the same species. But no--they are three +distinct species, exhibiting to a careful observer many important marks +by which each may be known from the other two. + +On Plate I (fig. 3) will be seen a picture of the female _Brassicae_, in +which the following markings are depicted: On each fore wing--a blotch +at the tip, a round spot near the centre, another round one nearer the +inner margin, and a tapering spot on the inner margin with its point +toward the base of the wing. On the hind wings there is only one spot, +situated near the middle of the costal margin. + +The male may be readily distinguished by the absence of the black +markings on the fore wings, with the exception of those at the tips. He +is also a trifle smaller than his mate. + +This butterfly is double-brooded. The first brood appears in April and +May, the second in July and August; and the former--the spring +brood--which emerges from the chrysalides that have hybernated during +the winter, have _grey_ rather than black tips to the front wings. + +The ova of _Brassicae_ may be found on the leaves of cabbages in every +kitchen garden, also on the nasturtium, during May and July. They are +pretty objects (see fig. 10), something like little bottles or +sculptured vases standing on end, and are arranged either singly or in +little groups. + +As soon as the young larvae are out--from ten to fifteen days after the +eggs are deposited--having devoured their shells, they start feeding on +the selfsame spot, and afterwards wander about, dealing out destruction +as they go, till little remains of their food plant save the mere stumps +and skeletons of the leaves. + +The ground colour of the caterpillar is bluish green. It has a narrow +yellow stripe down the middle of the back, and two similar but wider +stripes along the sides; and the surface of the body is rendered +somewhat rough by a number of small black warty projections, from each +of which arises a short hair. + +When fully grown, it creeps to some neighbouring wall or fence, up which +it climbs till it reaches a sheltering ledge. Here it constructs its +web and silken cord as already described (page 36), and then changes to +a bluish-white chrysalis, dotted with black. The butterflies of the +summer brood emerge shortly after, but the chrysalides of the next brood +hybernate till the following spring. + +It is remarkable that we are so plagued with 'Whites' seeing that they +have so many enemies. Many of the insect-feeding birds commit fearful +havoc among their larvae, and often chase the perfect insects on the +wing, but perhaps their greatest enemy is the ichneumon fly. + +Look under the ledges of a wall of any kitchen garden, and you will see +little clusters of oval bodies of a bright yellow colour. Most gardeners +know that these are in some way or other connected with the caterpillars +that do so much damage to their vegetables. They are often considered to +be eggs laid by the larvae, and are consequently killed out of pure +revenge, or with a desire to save the crops from the future marauders. + +No greater mistake could be made. These yellow bodies are the silken +cocoons of the caterpillar's own foes. They contain the pupae of the +little flies whose larvae have lived within the body of an unfortunate +grub, and, having flourished to perfection at the expense of their host, +left its almost empty and nearly lifeless carcase to die and drop to the +ground just at the time when it ought to be working out its final +changes. Often you may see the dying grub beside the cluster of cocoons +just constructed by its deadly enemies. Should you wish to test the +extent of the destructive work of these busy flies, go into your garden +and collect a number of larvae, and endeavour to rear them under cover. +The probability is that only a small proportion will ever reach the +final state, the others having been fatally 'stung' before you took +them. + + +_The Small White_ (_P. Rapae_) + +This butterfly closely resembles the last species except in point of +size. The male, represented on Plate I (fig. 4), has a dark grey blotch +at the tip of each fore wing, a round spot of the same colour beyond the +centre of that wing, and another on the costal margin of the hind wing. +The female may be distinguished by an additional spot near the anal +angle of the fore wing. + +Although this and the two other common butterflies (_Brassicae_ and +_Napi_) that frequent our kitchen gardens are usually spoken of as +'Whites,' a glance at a few specimens will show that they are not really +white at all, but exhibit delicate shades of cream and yellow, inclining +sometimes to buff. The under surfaces are particularly noticeable in +this respect, for here the hind wings and the tips of the fore wings +display a very rich yellow. + +The species we are now considering is also very variable both in its +ground colour and the markings of the wings. The former is in some cases +a really brilliant yellow; and the latter are in some cases entirely +wanting. + +_Rapae_ is double-brooded, the first brood appearing in April and May, +and the other in July and August. + +During these months the eggs may be seen in plenty on its numerous food +plants, which include the cabbages and horse-radish of our gardens, also +water-cress (_Nasturtium officinale_), rape (_Brassica Napus_), wild +mustard (_B. Sinapis_), wild mignonette (_Reseda lutea_), and nasturtium +(_Tropaeolum majus_). + +The eggs are conical in form--something like a sugar loaf, with ridges +running from apex to base, and very delicate lines from ridge to ridge +transversely. + +The young larvae often make their first meal of the shell, and then +attack the food plant so voraciously that they are fully grown in about +three or four weeks. In colour they are of a beautiful glaucous green, +hardly distinguishable at times from the leaves on which they rest. A +yellow stripe runs along the middle of the back, and lines of yellow +spots adorn the sides; and the whole body is covered with very short +hairs, each one arising from a minute warty projection. + +The pupae may be found during the same seasons and in the same situations +as those of _Brassicae_. They are very variable in colour. Some are of a +very pale grey or putty colour, some are decidedly brown, and others of +a greenish tinge; and they are often spotted and striped with dark grey +or black. + + +_The Green-veined White_ (_P. Napi_) + +A non-observant beginner at entomological work may easily mistake this +insect for the last species, for the ground colour and markings are very +similar, even to the features by which the sexes are distinguished from +each other; but an inspection of the under surface will give a ready +means of identification, for here the wing rays are bordered with black +scales which, by contrast with the rich yellow around them, often +appear of a greenish hue. The butterfly receives its popular name from +this circumstance. + +A careful observer, however, will readily find distinguishing marks on +the upper side, for here also the chief 'veins' are more or less +accompanied with black scales, especially the extremities of those of +the fore wings, where little triangular blotches are often distinctly +formed; and the dark veining of the under surface of the hind wings +frequently shows through. The under side of this insect is shown on +Plate I (fig. 5). + +This butterfly is not so abundant as the two preceding, but is widely +distributed throughout England, and is in most parts decidedly +plentiful. + +The first brood (for it also is double-brooded) appears during April and +May, and the second in July and August. + +The eggs are very similar to those of _Rapae_, resembling ribbed and +striated sugar loaves; and the larvae are of the same rich glaucous +green, but may be identified by the black spiracles surrounded by yellow +rings. In our gardens we may find both eggs and larvae on mignonette and +horse-radish; the other food plants of this species include the +water-cress (_Nasturtium officinale_), winter cress (_Barbarea +vulgaris_), rape (_Brassica Napus_), cuckoo-flower (_Cardamine +pratensis_), and Jack-by-the-hedge (_Sisymbrium Alliaria_). + +The pupa is greenish, and marked with small black dots. + + +_The Bath or Green-chequered White_ (_P. Daplidice_) + +There is no doubt that many butterflies migrate from one country to +another across the seas; and as the Bath White is very common on the +other side of the Channel, and has been taken very sparingly in England +almost exclusively in the south-east, it is highly probable that the +majority of those that have been captured here are specimens that have +taken a voluntary trip across the water, or have been blown over during +rough weather. + +This butterfly is one of our greatest rarities, and the capture of a +specimen in England is an event that must necessarily be recorded in our +entomological literature. It seems that _Daplidice_ has bred in England, +for its caterpillars have been found at large on one or two occasions, +so I will give a short description of the various stages of the insect, +with a hope that some of my readers may be fortunate enough to meet with +it. + +The female butterfly is shown on Plate I, fig. 6. From this it will be +observed that each of the fore wings is tipped with a rather large +smoky-black blotch, in which are four white spots. A double spot of the +same colour also occupies a place near the centre of the wing, and +another smaller and round one lies near the anal angle. The hind wings +are clouded with grey, and bordered along the hind margin with distinct +smoky-black spots. + +The male may be distinguished from the female by the absence of the spot +near the anal angle of the fore wings, and of all the clouds and spots +of the hind wings. Nevertheless the latter have a decidedly clouded +appearance, but this is due to the markings of the under surface showing +through them. + +The under side of both sexes is most beautifully marked--the fore wings +resembling the upper sides, but the hind pair chequered with a beautiful +soft green on a pale yellow ground. + +The eggs of this insect are deposited during April and May, and again in +August or September--for it is, like the other 'Whites,' +double-brooded--on two species of Wild Mignonette (_Reseda lutea_ and +_R. luteola_). + +[Illustration: FIG. 65.--THE BATH WHITE--UNDER SIDE.] + +The caterpillars, which are of a bluish colour, with two yellow stripes +down the back, and two others along the sides, may be _looked_ for in +June and September. Those of the first brood only have been taken in +this country, while the others on the Continent change to the chrysalis +in the autumn, and hybernate in this state throughout the winter. + +The chrysalis is of a brownish colour, and closely resembles that of the +Small White in form. + +Those in search of this rare British insect should wander along the +south-east coast, and net all the doubtful slow-flying small Whites +(_Daplidice_ is rather slow and heavy on the wing), and their +perseverance _may_ be rewarded with a prize that will ever be a reminder +of a glorious catch and an eventful day. If you fail in this, and most +probably you will, rather than remain a stranger to this beautiful and +interesting insect, fill up the blank in your cabinet with a foreign +specimen, which can be obtained at any time for a few pence, but be +careful to label it 'not British,' in order that your brother +collectors may not be deceived, or be led to make any unnecessary +inquiries. + + +_The Orange Tip_ (_Euchlo[:e] Cardamines_) + +No one could possibly mistake the male of this species for any other +British butterfly, the popular name alone giving quite sufficient +information for its identification, but the female Orange Tip is _not_ +tipped with orange, and its markings, both above and beneath, resemble +those of _Daplidice_ so nearly that the same written description might +apply almost equally well to both. + +On Plate I (fig. 7) is shown the upper side of the male, and just +opposite it (fig. 8) the under surface of the same. The female is +usually a little larger than her mate, and is marked similarly on both +sides except that the bright orange blotch is entirely wanting. She may +always be distinguished from _Daplidice_ by the smaller size of the +white spots that break the dark blotch at the tip of the fore wing; also +by the very small size of the dark spot in the centre of the same wing. +The green chequerings of the under side of the hind wings are also more +sharply defined, and the insect is generally of a lighter build. + +Like many other butterflies, the Orange Tip is subject to variations in +colouring. Sometimes a pale but bright yellow takes the place of the +white ground, and the orange blotch of the male is occasionally present +on the upper or lower surface only. + +_Cardamines_ is a single-brooded insect, and is essentially a creature +of the spring, at which time it may be found in abundance in lanes, +meadows, and clearings in woods throughout the British Isles. Its flight +is so light and airy that even the female may easily be distinguished +from other Whites when on the wing, while the brilliant orange of the +male, intensified by the bright rays of the spring sun, may be +identified at some considerable distance. + +The food plants of _Cardamines_ include the cuckoo-flower (_Cardamine +pratensis_) and the bitter cress (_C. impatiens_), after which the +insect is named, also water-cress (_Nasturtium officinale_), winter +cress (_Barbarea vulgaris_), rock cress (_Arabis perfoliata_), hedge +mustard (_Sisymbrium officinale_), Jack-by-the-hedge (_S. Alliaria_), +wild mustard (_Brassica Sinapis_), &c., and the eggs of the butterfly +may be found on these during May and June. + +The caterpillar (Plate VIII, fig. 2) is green, with a white stripe on +each side, and its body is covered with short hair. In July it is fully +grown, and ascends a stem of the food plant to prepare itself for its +long winter sleep. + +The chrysalis (Plate VIII, fig. 8) is a very peculiar object. Both ends +are much elongated and sharply pointed; and the foremost extremity +stands out at an angle with the stem to which it is attached. + +This butterfly should be looked for during April and May, but in mild +seasons it may often be met with in March. + + +_The Wood White_ (_Leucophasia Sinapis_) + +The distinguishing feature of this butterfly (see Plate II, fig. 1) is +the extreme lightness and delicacy of its build. Its wings are narrow, +and rounded at the tips; and the only mark to relieve the white ground +of the upper side is a squarish blotch at the tip of the fore wing, and +even this is either very indistinct or entirely absent in the female. +The under surface is clouded with a pale greenish tint. + +This insect may be looked for in May and again in August, in paths and +clearings in woods, where it moves along with a slow but steady flight, +hardly ever seeming to rest for a moment. It is not by any means a +common butterfly, but is very widely distributed, and sometimes appears +in considerable numbers in certain favoured spots. Among the localities +recorded may be mentioned Torquay, Exeter, Plymouth, South Dorset, New +Forest, Reading, Darent Woods, Morecambe Bay, Haslemere, Windermere, &c. + +The caterpillar is of a beautiful green colour, and is covered with +short whitish hairs. A darker green stripe runs down the middle of the +back, and a bright yellow stripe along each side. Its food plants are +the tufted vetch (_Vicia Cracca_), bird's-foot trefoil (_Lotus +corniculatus_ and _L. pilosus_), bitter vetch (_Lathyrus tuberosus_), +and the everlasting pea (_L. sylvestris_). + +The chrysalis is a very beautiful object. Its colour is a delicate +green, tinged with pink; and the wing-cases project in beautiful curves +much beyond the general surface. + + +_The Pale Clouded Yellow_ (_Colias Hyale_) + +The ground colour of this butterfly (Plate II, fig. 2) is very variable. +It is usually a sulphury yellow, and on this account the insect is +commonly known as the Clouded Brimstone; but sometimes the yellow is +exceedingly pale--almost white--and tinged with green. + +A very large black blotch, broken by indefinite patches of the ground +colour, fills up the tip of each fore wing, and extends to the anal +angle, becoming narrower as it approaches this point. A black oval spot +lies just above the middle of this wing. + +The hind wings are bordered with black, and a conspicuous spot of deep +yellow lies very near the centre of each. + +The antennae are rather short, compared with those of the preceding +members of this family, and are distinguished by their reddish-brown +colour. + +The male and female of this species are similarly marked, but the ground +colour of the latter is commonly paler. + +This is not by any means a very common butterfly with us, though it is +very plentiful on the other side of the Channel; but it has a way of +taking us by surprise in certain seasons, and then almost neglecting us +for several years together. + +Its head quarters are certainly the coasts of Kent and Sussex, but it +has been taken in considerable numbers as far west as Cornwall, and also +to a less extent in some of the midland and northern counties. It is +particularly fond of lucerne and clover fields, especially those that +are situated close to the sea cliffs; and often it may be seen flying +over the beach, sometimes even flitting over the breakers away from land +till at last it disappears in the distance. This maritime tendency of +_Hyale_ makes it probable that a large number of those that are seen on +our south-east coasts have made a passage across the narrow end of the +Channel. + +The eggs are laid in spring, by females that have hybernated throughout +the winter, on various leguminous plants, including the lucerne +(_Medicago sativa_), black medick (_M. lupulina_), purple and Dutch +clovers (_Trifolium pratense_ and _T. repens_), and the bird's-foot +trefoil (_Lotus corniculatus_), and on these plants you may search for +the larva, though it can scarcely be said that you are likely to find +it. + +The caterpillar is green, with black dots, and a yellowish stripe on +each side. When fully grown it ascends a stem of its food plant and +changes to a green chrysalis with yellow stripes. + +_Hyale_ is single-brooded in England, although two broods regularly +appear on the Continent. In our country the perfect insects emerge +during July and August. Many of these die before the approach of winter; +but, as we have already observed, some hybernate and deposit their eggs +in the following spring. + + +_The Clouded Yellow_ (_Colias Edusa_) + +Not only are this and the last species similarly named, but a glance at +the figures will show that they much resemble each other in appearance; +and we shall also learn presently that in their habits and life history +they have much in common. + +The male _Edusa_ is shown on Plate II (fig. 3), and when we compare it +with its relative on the opposite side, we are at once struck with the +superior richness of the brilliant orange or saffron of the ground +colour. The black border of both fore and hind wings is also denser, +wider, and more extensive. The whole of the yellow area of the hind +wings is dusted more or less with black scales, with the exception of a +round central spot of deep orange, corresponding with the orange spots +on the hind wings of _Hyale_. + +The female, which is shown in the accompanying woodcut, is generally +larger than the male, and is further distinguished by the very pale +yellow spots that break the black border of both pairs of wings. + +[Illustration: FIG. 66.--THE CLOUDED YELLOW--FEMALE.] + +_Edusa_ further resembles _Hyale_ in the reddish colour of the antennae; +and, in both the species, the red legs form a pleasing contrast with the +yellow furry surface of the under side of the thorax. + +There is a variety of the female of this butterfly, in which the ground +colour is a _very pale_ yellow, almost white. The hind wings are more +thickly dusted with black scales than in the normal insect, and the +orange spots of these wings show up much more conspicuously from the +contrast with their surroundings. + +It is usual to apply distinct names to constant varieties of +species--names that are to be added to the ordinary title. In this +particular case the distinguishing name is _Helice_, so that we should +speak of the variety of _Edusa_ above mentioned as: + + +_Colias Edusa_, var. _Helice_ + +Like _Hyale_, _Edusa_ is particularly capricious in its appearance. In +certain summers it absolutely swarms in favourite localities, while +during the intervals between such remarkable appearances--usually +several years--it is positively scarce. The last favoured season was the +summer of '92, during which (from the beginning of August to the end of +the summer) dozens might easily have been caught in an hour or two; in +fact, so plentiful were they in many places, that they were continuously +in sight, often several at one time. + +Those in search of this insect should repair to the south coast, +especially the south-east, and where lucerne and clover fields are in +flower. It has very decided maritime tendencies, and may often be seen +flying over the cliffs and beaches, and even skipping over the breakers; +but, at the same time, it is more or less plentiful in many inland +districts. It has been taken in many parts of Ireland and Scotland, +particularly along the southern coasts of these countries; but its head +quarters are undoubtedly the southern cliffs of England, from Cornwall +to Kent, and also the hilly inland districts of the south-eastern +counties. + +_Edusa_ catching is very lively sport, and is likely to prove sufficient +for any lover of outdoor exercise under a scorching sun; for this +butterfly is not only very powerful on the wing, but its flights are +usually long, so that a good run is often absolutely necessary in order +to capture it. On very hilly ground, such as _Edusa_ loves, chase is +often hopeless, and then it is necessary to resort to stratagem. In such +a case the best plan is to make a very cautious approach when the insect +has been observed to settle, and then secure it with a sudden +down-stroke of the net. + +The eggs are laid during May and June by a few females that have +survived the winter. + +The caterpillar may be found in June and July on its food plants, the +chief of which are the bird's-foot trefoil (_Lotus corniculatus_), and +the purple and Dutch clovers (_Trifolium pratense_ and _T. repens_). Its +colour is grass-green, and it is marked with a narrow whitish stripe on +each side, which is broken by the yellow of the spiracles. + +The chrysalis is of a pale yellowish green, and is marked with yellow +stripes and reddish-brown dots. + + +_The Brimstone_ (_Gonopteryx Rhamni_) + +This, the last member of the present family, is remarkable for the +graceful outline of its wings. The costal margins of the fore pair are +most beautifully arched, and both pairs are sharply angled on the hind +margins. This latter characteristic is quite unique among British +butterflies, though we shall presently meet with instances of angular +projections on hind wings only. + +The ground colour of the male (Plate II, fig. 4) is a rich sulphury +yellow, with a greenish tinge. That of the female is a very pale +greenish yellow. The only conspicuous markings are small saffron spots, +one near the centre of each wing. The antennae are red, short, and +beautifully curved; but, unlike the two preceding species, the legs are +almost white. + +The eggs of this butterfly are laid in April on the two species of +buckthorn (_Rhamnus catharticus_ and _R. Frangula_) by the females that +have successfully weathered the winter. They are of a bright yellow +colour, and are usually hatched in about a fortnight. + +The body of the caterpillar is green, and it is thickly covered with +little black wart-like projections. A pale stripe also runs along each +side. During May and June it may be found on its food plants, and toward +the end of the latter month it attaches itself by a silken carpet and +belt to the under side of one of the leaves. + +The chrysalis is of a very peculiar shape, the body being curved, and +the wing cases standing out prominently beyond the general surface. Its +colour is a bright apple green marked with yellow, and it is so +transparent that certain of the structures can be seen through its skin. + +The perfect insect emerges in about three weeks after the change to the +chrysalis; and may be looked for from July to the end of the summer. +This period may be regarded as the best time in which to hunt for +_Rhamni_, but it is to be noted that this butterfly makes its appearance +during all months of the year, even though it is single-brooded. + +A large number seem to hybernate, and their winter sleep is so light +that the welcome rays of the sun on a mild day, even during the bleak +months of November to February, will often call them out from their +hiding places. Then, as a rule, the hybernating butterflies do not live +long after depositing their eggs for the future brood; but the Brimstone +often lives on till its offspring have themselves attained the perfect +state, so that it is possible to capture the insects of two different +years both on the same day. In such a case it is generally easy to +distinguish between the two, for the newly emerged specimens are +beautifully bright and fresh in colour, while those of the previous year +are more or less faded and worn, their wings being often +semi-transparent through the loss of scales, and frequently disfigured +by the stains of mildew. + + + + +CHAPTER XIII + +_THE FRITILLARIES, VANESSAS, AND THE PURPLE EMPEROR_ + + +Family--NYMPHALIDAE + +We now come to a rather large family, which contains some of our largest +and most brilliant butterflies. Some of them display the most gaudy +colours, and others exhibit patches of a beautiful metallic lustre. + +If you were to see all the members of this family side by side, they +might strike you as being so varied in their appearance that you would +wonder why they are all placed in one family group. But, were you to +see, in addition to the perfect insects, all their larvae and +chrysalides, the reason would be made clear at once, for these earlier +stages are seen to resemble each other in certain points at the very +first glance. The former are all provided with peculiar spines, and the +latter are all more or less angular, and are all suspended to a silken +carpet by means of hooks at the tip of the abdomen, and have no belt as +we have observed in the case of the _Pieridae_. + +The perfect insects, too, although so varied in colouring, are alike in +that they have only four walking legs, the first pair being so +imperfectly developed as to be useless for this purpose. + +This family includes the Fritillaries and the Vanessas. + + +_The Small Pearl-bordered Fritillary_ (_Argynnis Selene_) + +The interesting group of butterflies known as the Fritillaries vary +considerably in size, but are remarkably uniform in the ground colour of +the wings, which, in all cases, is a rich golden or sienna brown; and +this ground is chequered with darker colours in such a manner as to +remind one of the petals of the wild flower known as the Snake's Head +or Fritillary--hence the popular name of the group. + +The Small Pearl-bordered, our first example, is one of the lesser +Fritillaries, and is shown in Plate II (fig. 5). + +The arrangement of the black markings on the upper surface will be +readily made out from the coloured plate, but the pattern of the under +side will require a little special notice, for it is here, as with the +other Fritillaries, that we find the chief marks by which we identify +the species. On this side (fig. 67) the fore wings are light orange +brown, with a patch of darker brown near the tips, and spotted with a +dull black. The hind wings have the light brown displaced by a very warm +chestnut tint, some yellow, and bright silvery spots. + +[Illustration: FIG. 67.--THE SMALL PEARL-BORDERED FRITILLARY--UNDER +SIDE.] + +Seven silvery spots of triangular form border the hind margin. A large +one occupies the centre of the wing, and ten others are somewhat +irregularly scattered over other parts of the wing--five between the +central spot and the hind margin, and five between it and the costa. + +All the spots on these wings, whether yellow, chestnut, or silver, are +bordered by a narrow black line. + +_Selene_ is not a very abundant butterfly, but is widely distributed in +England, and is also found in parts of Scotland. Its favourite resorts +are clearings in woods, especially those of Kent and other southern +counties. + +It appears in May and June, in which latter month it deposits its eggs +on the dog violet (_Viola canina_). + +The caterpillar is not fully grown at the end of the summer, and +hybernates during the winter among the roots of its food plant. In the +following spring it emerges again, and feeds till May, when it changes +to the chrysalis on a stem. It is less than an inch long when fully +grown, and is of a dark-brown colour. Six rows of hairy spines are +arranged longitudinally on its body. + +The chrysalis is greyish brown, and has a number of very short +projections corresponding with the spines of the caterpillar. + + +_The Pearl-bordered Fritillary_ (_Argynnis Euphrosyne_) + +There is very little difference in the size of this and that of the last +species, but _Euphrosyne_ (Plate II, fig. 6) is generally a trifle +larger. The two butterflies are also very similar in appearance; indeed, +they are so much alike on the upper side that it is impossible to decide +on the name of either without an examination of the under surface. + +_Euphrosyne_ has a border of seven triangular silver spots on each hind +wing, exactly corresponding with those of _Selene_. It has also the +large central spot of silver. But, beside these, there is _only one_ +other, and that is situated in the basal angle. Thus there are only nine +silvery or pearly spots on each hind wing of _Euphrosyne_, while there +are seventeen on _Selene_. This will form a ready means of +distinguishing between the two species. + +[Illustration: FIG. 68.--THE PEARL-BORDERED FRITILLARY--UNDER SIDE.] + +The seasons and localities of this butterfly correspond very closely +with those of the last species, but it is much more common, and may be +found in abundance in nearly all our southern woods during May and June. + +The caterpillar, also, feeds on the same plant (dog violet) as _Selene_. +It is black, with whitish lines along the sides; and is provided with a +number of bristly spines. + +The chrysalis is of a grey-brown colour, with small dots of a paler tint +on the wing cases; and its body has a number of short conical +projections exactly corresponding with the spines of the caterpillar. + + +_The Queen of Spain Fritillary_ (_Argynnis Latona_) + +We now pass from the commonest to the rarest and most prized of our wood +butterflies--The Queen of Spain (Plate II, fig. 7). This royal personage +is not easily mistaken for any of the meaner Fritillaries even when the +upper surface only is examined, as the concave hind margins of the fore +wings serve as an almost conclusive mark of distinction. The rich tawny +brown of this side is boldly marked with black, and the long hairs and +scales of the bases of the wings are tinged with green. + +The under side presents a most beautiful appearance. Here the ground +colour is paler than that of the upper side. The fore wings are spotted +with black, and have a few small patches of silver at the tips. Each +hind wing has no fewer than twenty-four bright silvery spots. Seven of +these, mostly of large size, adorn the hind margin, and above each of +these is a small one in the middle of a little patch of dark brown. The +arrangement of the others is not quite so easily described, but may be +readily made out from our illustration. + +[Illustration: FIG. 69.--THE QUEEN OF SPAIN FRITILLARY--UNDER SIDE.] + +This rare gem among British butterflies has been taken in many +localities, but in very small numbers. Seeing that it is a common insect +on the other side of the Channel, and that the British captures have +been made chiefly in the Isle of Wight and on the south coast, I am +inclined to believe that many of the highly valued genuine Britishers +have no right to their title, but are visitors that have spent only a +few days within our shores, having flown or been blown across the sea. + +It is not likely that many of my readers will ever meet with _Latona_ +during their rambles in our own country, and if they are anxious to have +the species represented in their collections, they will probably have to +purchase either a British or a foreign specimen, the former of which +will command a very high price, while the latter may be obtained for +three or four pence. + +The perfect insect may be looked for in August and September, during +which time the eggs are laid on the leaves of violets and the heartsease +(_Viola canina_, _V. odorata_, and _V. tricolor_). + +The caterpillar is brown, with numerous yellowish spines, and has three +whitish or yellowish stripes--one down the middle of the back and one +along each side. It hybernates during the winter, and is fully grown in +the following June or July. I hope that my reader will be so fortunate +as to secure either this or some other stage of this rare and beautiful +insect. The chances are decidedly against him, but that is no reason +why he should abstain from a vigorous search when he happens to be +'doing' the southern counties. + + +_The Dark-green Fritillary_ (_Argynnis Aglaia_) + +This butterfly is larger than _Latona_, as will be seen by reference to +Plate II, fig. 8. Its colour is, as usual with the Fritillaries, a tawny +brown with black markings. The female is usually larger than the male, +and she is further distinguished by the ground colour being darker and +the black markings larger. + +The under side of the fore wings is very similar in colour and markings +to the upper, but there are silvery spots near the tips. The hind wings +are beautifully tinted with olive green and brown, and studded with +silver. The arrangement of the latter is not easily described, but is +accurately represented in the accompanying woodcut. + +[Illustration: FIG. 70.--THE DARK-GREEN FRITILLARY--UNDER SIDE.] + +The favourite resorts of this insect are wooded spots, and also heaths +and downs clad with heather or ferns, where its food plant (the dog +violet) lies scattered; but it seems to be less partial to woods than +the other Fritillaries. It is very widely distributed throughout +England, and is common in parts of Scotland and Ireland. + +The perfect insect is on the wing in July and early August. + +The caterpillar first appears toward the end of August, and commences +its period of hybernation among the roots of its food plant before it +has grown to any considerable size. It comes out again in the spring, +and continues to feed till the beginning or middle of July, and then +changes to the chrysalis state, after protecting itself by binding three +or four leaves together. + +Its colour is a velvety black, with dark and glossy grey between the +segments. There is a double yellow line along the back, and a thin line +of orange yellow on each side below the spiracles. It has a number of +black hairy spines, arranged in six longitudinal rows. + +The chrysalis is of a shiny black colour, with brownish abdomen; and the +conical projections are black with yellow tips. + + +_The High-brown Fritillary_ (_Argynnis Adippe_) + +The upper side of this butterfly is so much like that of _Aglaia_ that +it would be difficult indeed to give a written description of one that +did not almost equally well apply to the other; so we look to the under +surface for the chief marks by which we can distinguish between them. + +On this side (Plate III, fig. 1) the fore wings are much the same as +those of _Aglaia_. The hind wings, too, are very similarly coloured and +marked, but here we have a distinguishing feature in a row of rust-red +spots with silvery centres, just inside the silver border of the hind +margin. + +[Illustration: FIG. 71.--THE HIGH-BROWN FRITILLARY.] + +This butterfly is common in open spaces of woods in many parts of +England, more particularly in the south, and seems to be also fond of +hilly heaths and moors. + +It is on the wing in July, and, towards the end of this month and in the +beginning of August, the eggs are laid on the leaves of the dog violet +(_Viola canina_) and heartsease (_V. tricolor_). + +The young caterpillar emerges about two weeks later, and feeds only for +a short time before it seeks out its winter quarters among the dead +leaves at the root of its food plant. The feeding is resumed in the +spring, and continued till the month of June, when it is fully grown. At +this time it is about an inch and a half long. Its head is black, and +its body pinkish brown. A white line extends down the back, but is +interrupted by several black marks. The spines, of which there are six +rows, are white, with pinkish tips. + + +_The Silver-washed Fritillary_ (_Argynnis Paphia_) + +This beautiful and noble butterfly is the largest of the Fritillaries, +and the most powerful on the wing. During the latter part of June and +throughout July it may be seen gracefully sweeping through the trees and +undergrowth of woods, often settling down on a favourite flower for a +short time. So strong is its flight that it is useless to attempt to +pursue it for any distance. Sometimes it will sail along a wooded path, +followed at short intervals by others of its species, and may be taken +in the net as it passes. But perhaps the most successful method of +netting _Paphia_ is to wait till it has settled, and then secure it by a +quick upward or side stroke of the net. If then you miss your aim, off +it will dart, sailing over the tree tops till, in a very short time, it +is quite out of sight. + +[Illustration: FIG. 72.--THE SILVER-WASHED FRITILLARY--UNDER SIDE.] + +The upper side of this butterfly is shown in Plate III, fig. 2, where +the general arrangement of the black spots on the rich orange-brown +ground is carefully marked. There is a considerable difference between +the male and female of this species. The figure on Plate III represents +the male. The female does not possess the broad black lines that follow +the course of the veins of the fore wings; the basal portions of all +four wings are also tinged with a rich olive-brown colour, often with a +decided tendency to green; and the black spots of all the wings are +larger. + +The under side is particularly rich in its decorations. The front wings +are of the usual orange brown, chequered with black. The hind wings are +partly brown and partly orange, and exhibit beautiful greenish +reflections. They have also two bars of silver, and a silvery spot in +the basal angle, all with rather indefinite outlines. + +The female lays her eggs late in July on the food plants (_Viola canina_ +and _V. odorata_) or on the moss that surrounds them. + +About two weeks later the young caterpillar is out and feeding; and +then, after a few more weeks, while it is yet very small, it hides among +the dead leaves at the roots. Early in the spring it resumes its +feeding, and is full grown at the end of May. + +The colour of the caterpillar (Plate VIII, fig. 3) is black, and there +are two yellow lines along the back, separated by a black stripe, also +one yellowish line on each side. Its body is adorned with reddish-brown +spines, two of which, situated just behind the head, are longer than the +others. + +The chrysalis (Plate VIII, fig. 9) is greyish, marked with metallic +spots, and has a number of angular projections representing the spines +of the larva. + +_Paphia_ is to be met with in woods in all parts of England and Wales. +It has also been observed in Ireland, but is rarely seen in Scotland. + + +_The Greasy Fritillary_ (_Melitaea Aurinia_) + +Unlike the other Fritillaries, this species (Plate III, fig. 3) exhibits +a variety of shades on the upper surface. A broad band of sienna brown +stretches across each wing, near to and parallel with the hind margin. +The other parts of the wings are marked with patches of sienna, orange, +and yellow, separated by black lines and bands. The margins are all +black, and inside the broader margin of the hind wing is a row of six +very pale yellow spots. The broad sienna band of the hind wing is also +divided by narrow black lines into seven parts, six of which have black +centres. + +[Illustration: FIG. 73.--THE GREASY FRITILLARY--UNDER SIDE.] + +The under surface of the fore wings has indefinite yellowish and tawny +patches, which look as if they had been greased and smeared. The hind +wings are marked with pale yellow and deep orange; a broad band of the +latter, near the hind margin, is divided into segments, each of which +has a yellow spot with black in the centre. + +This is a very local insect, although it is widely distributed +throughout England and Wales. It also occurs sparingly in Scotland and +Ireland. Its food plants are the honeysuckle (_Lonicera_ +_Periclymenum_), devil's-bit scabious (_Scabiosa succisa_), and the +plantain (_Plantago_); and its chief resorts are damp meadows and marshy +places, where these plants (more especially the scabious) abound. + +The butterfly appears about the end of April or in June. + +The caterpillars emerge from the eggs towards the end of the latter +month, and always feed in groups under the cover of a silken web. Like +the preceding species they hybernate during the winter, and commence +feeding again in the spring. They are fully grown about the end of +April. + +In colour the caterpillar is velvety black, dotted with white, and its +body is covered with short bristly spines. When fully fed it seeks the +shelter of a curled leaf or dense herbage, suspends itself by the hind +claspers to a silken carpet, and then changes to a creamy white +chrysalis with black dots. + + +_The Glanville Fritillary_ (_Melitaea Cinxia_) + +The pattern of the upper side of this Fritillary (Plate III, fig. 4) is +very similar to that of _Aurinia_, but the ground colour is a uniform +tawny brown, and the fringes of the wings are of a very pale straw +colour, barred with black. + +The under side of the fore wings is tawny brown, with straw-coloured +tips bearing black markings. The hind wings have four alternate bands of +brown and straw colour, and a patch of straw colour at the base. The +marginal yellow band has six or seven black spots. The brown band next +to it is divided into six segments with black borders, each with a black +spot. The next yellow band has also a row of black spots. The inner +fulvous band is very irregular; and inside this is the yellow base with +six spots. + +[Illustration: FIG. 74.--THE GLANVILLE FRITILLARY--UNDER SIDE.] + +This is another local insect--very local indeed, for it seems to have +been found only in a few spots outside its head quarters, the Isle of +Wight. Those in search of it should carefully scan the rough cliffy +parts of the island, wherever the species of plantain (_Plantago +Coronopus_ and _P. maritima_) are plentiful, these being the food plants +of the larvae. It first appears on the wing in May, but may be found till +the end of June. + +The caterpillars, which are black and spiny, with reddish head and legs, +begin to feed in August, and as soon as the chilly weather sets in they +hybernate in groups under the cover of a tent constructed by binding +together leaves or blades of grass. In the spring they start out again, +and feed till the end of April, at which time they change to dark +brownish and smooth chrysalides. + + +_The Heath Fritillary_ (_Melitaea Athalia_) + +Both the upper and under sides of this butterfly are shown on Plate III +(figs. 5 and 6), and it will be observed from these that its general +appearance is very similar to that of _Cinxia_. + +The upper surface is of the same tawny brown, barred and striped with +black, and the fringes of the wings are pale yellow, interrupted by +small patches of black. + +The under surface of the fore wings has the same ground colour with the +exception of the tips, which are yellow; and the whole is marked with +black, as in the illustration. The hind wings are pale yellow, with two +broad bands of brown corresponding with those of _Cinxia_; but a series +of black double arches along the hind margin and the _absence_ of rows +of black spots serve to distinguish this species from the last. + +_Athalia_ is another local butterfly, but is sometimes found in +abundance in the spots which it frequents. It is met with chiefly in the +open spaces of woods along the south coast and for some distance inland. +Devon, Cornwall, Sussex, and Kent seem to be the most favoured counties; +and London entomologists would do well to search for it in Epping +Forest. + +The butterfly deposits its eggs during June and July, on several +different food plants, the chief of which are the greater and +narrow-leaved plantains (_Plantago major_ and _P. lanceolata_), foxglove +(_Digitalis purpurea_), two species of cow-wheat (_Melampyrum pratense_ +and _M. sylvaticum_), wood sage (_Teucrium Scorodonia_), and the +germander speedwell (_Veronica Chamaedrys_), and the young caterpillars, +after feeding for only a week or two, commence their period of +hybernation. They resume their feeding in April, and change to the pupal +state about the end of May. + +The colour of the caterpillar is velvety black, finely dotted with +white, and the spines are yellow or orange, tipped with white. + +The chrysalis is creamy white, banded and patched with orange and +black, and is suspended by anal hooks from a silken, carpet which the +caterpillar had spun on the leaf of the food plant. + + +_The Comma_ (_Vanessa C-Album_) + +Leaving the Fritillaries, we now come to a genus (Vanessa) that includes +seven most beautiful butterflies, some of which are so common as to be +known to almost everybody. + +It will be observed that this genus belongs to the same family as the +Fritillaries, and we may therefore expect to find that the two groups +possess features in common. A slight examination of a few in their +different stages will show that this is so. Thus, the perfect insects +have only four walking legs, the caterpillars are all spiny, and the +chrysalides are angular. + +[Illustration: FIG. 75.--THE COMMA--UNDER SIDE.] + +There is another feature concerning the chrysalides worthy of note. Like +some of the pupae of the Fritillaries, they are adorned more or less with +brilliant metallic spots, sometimes of a rich golden hue, and sometimes +resembling burnished silver. Now the word 'chrysalis,' which, as we have +already seen, is derived from a Greek word meaning 'gold,' was +originally applied to the pupae of some of the Vanessas, on account of +their metallic decorations, but it has since been extended to the pupae +of all the Lepidoptera, and also to other orders of insects, even though +the greater number of them display no tints of the precious metal. + +The first member for our consideration is the Comma Butterfly, of which +an illustration is given in Plate III, fig. 7. No one could mistake this +beautiful butterfly for any other British species, for its wings of rich +orange brown, with black and dark-brown markings, are so irregularly +scalloped on the hind margins that they present a somewhat ragged +appearance. Its name is derived from the fact that a white mark +something like the letter C, or, as some have it, like a comma, is +distinctly painted on the dark brown of the under side. + +This butterfly generally emerges from the chrysalis late in the +summer--August and September, but it is often seen earlier, and +frequently as late as October. It is a great lover of sweets, and may be +found settled on various flowers and fruits. Its chief food plants are +the hop (_Humulus Lupulus_), red currant (_Ribes rubrum_), stinging +nettle (_Urtica dioica_), and the Elm (_Ulmus campestris_). + +It is very abundant in certain districts where hops are grown, but seems +to avoid those counties that border the sea. It is widely distributed in +the midland counties, and extends to the north of England and into +Scotland, but is very capricious in its appearance in many parts. + +The eggs are laid in May by females that have hybernated through the +winter, and the caterpillars may be found feeding during July and +August. + +The caterpillar is coloured grey and brown, with a black head, and a +broad white stripe down the back of the hindermost segments. The body is +armed with a number of spines, some of which are white, and others pale +brown. + +The chrysalis is a very peculiar object, having two ear-like projections +extending forwards from the sides of the head. It has a number of +angular projections, and is of an umber-brown colour, finely netted with +black lines, and having several spots of a brilliant metallic lustre. + + +_The Large Tortoiseshell_ (_Vanessa Polychloros_) + +Our two tortoiseshells--large and small--are very similar in their +colour and markings, and moreover are not always to be distinguished by +their size, for specimens of the larger species are sometimes even +inferior in this respect to the largest of the smaller species; so, to +avoid all risks of mistaken identity, we must look for more reliable +marks of distinction between them. + +The present species is figured on Plate III (fig. 8), where it will be +seen that the ground colour of dark tawny brown is spotted and bordered +with black. The border of the hind wings contains a row of +crescent-shaped blue spots. The costal margin of the fore wings, between +the black patches, is decidedly lighter than the general ground, and is +yellow rather than brown. It will be noticed, too, that a black spot +lies very near the anal angle of these wings. + +The under surface, though by no means brilliant, exhibits a rich +blending of various shades of brown. + +This butterfly is not known to occur in either Scotland or Ireland, and +is by no means common in England. Its chief localities are in the +midland and eastern counties. + +The perfect insect generally appears about the middle of July, and after +spending a month or six weeks on the wing, seeks out a sheltered spot in +which to spend the winter. In the spring--April or May--it again takes +to flight, and during the latter month the females are busily engaged in +the deposition of their eggs. + +The caterpillar feeds on the two species of elm (_Ulmus campestris_ and +_U. montana_), willow (_Salix alba_), sallow (_S. Caprea_), osier (_S. +viminalis_), aspen (_Populus tremula_), and certain fruit trees; and is +full grown about midsummer. It is of a tawny grey colour, with a black +stripe on each side, and is covered with very small wart-like +projections, and the spines are branched. + +The chrysalis is of a dull pinkish colour, and may be found on tree +trunks, palings, and walls, about the end of June, suspended from a +silken carpet by means of its anal hooks. + + +_The Small Tortoiseshell_ (_Vanessa Urticae_) + +_Urticae_ (Plate III, fig. 9) may be distinguished from _Polychloros_ by +the _absence_ of the black spot in the anal angle of the fore wings of +the latter. It has also a white spot near the tip of each fore +wing-between the black border and the first black costal patch. The +whole of the base of the hind wing is also black, and the ground colour +is decidedly brighter. + +It is one of the commonest of all British butterflies, and is to be +found more or less abundantly in nearly all parts of the British Isles. + +The hybernated perfect insects come out early in the spring, and lay +their eggs in close irregular clusters on nettles (_Urtica dioica_ and +_U. urens_). Shortly after the gregarious caterpillars may be found on +these plants in dense masses. They change to the chrysalis state about +the end of May, and from this time there is a continuous succession of +butterflies till the end of the summer. + +The later specimens, which do not emerge till September or October, +spend only a short time on the wing, and then hybernate till the spring, +giving rise to the first brood of the following season. + +The caterpillar of this species is black above and greyish beneath. It +is thickly covered with yellow dots, which are so close together on the +back as to form two yellowish stripes, separated only by a fine black +line. There are also two yellowish stripes along each side; and the +body, as with the rest of this genus, is spiny, the spines in this case +being black or very dark green. + +The chrysalis is brownish, and spotted with burnished gold in variable +quantity--sometimes so plentifully as to cover the greater part of the +surface. + + +_The Peacock_ (_Vanessa Io_) + +This is another of our commonest and most beautiful butterflies. Its +general appearance is such that it cannot possibly be mistaken for any +other. The upper side (Plate IV, fig. 1) is rendered conspicuous by the +beautiful eye-like marks at the costal angles of all four wings; and the +under surface is very richly decorated with a fine arrangement of black +and dark-brown patches and streaks. + +Io is very abundant in all parts of England, and is well known in many +parts of Scotland and Ireland, but seems to be rare in the extreme north +of both of these countries. + +Its food plant is the stinging nettle (_Urtica dioica_), and on this the +eggs are laid in April by females that have hybernated during the +winter. + +The caterpillar is full grown at the end of June or beginning of July. +It is black, with numerous minute white wart-like projections. Its +spines also are black, and its claspers brown. + +The chrysalis may be found suspended by the tail on some object in the +neighbourhood of the food plant, or sometimes on the food plant itself. +It is of a greenish colour, with yellowish patches, but turns darker as +the time approaches for the emerging of the perfect insect. + +This event takes place in August, and the butterfly, after a brief +period on the wing, seeks out a sheltered spot for its winter nap. + + +_The Camberwell Beauty_ (_Vanessa Antiopa_) + +The reader will be fortunate if he succeeds in netting a specimen of +this highly prized British butterfly. It derives its popular name from +the fact that a few were taken in Camberwell about a hundred and fifty +years ago; and since that time it has been seen and taken in variable +numbers in several parts of England. So widely distributed, indeed, are +its localities, and so few, comparatively, its appearances, that it +would be useless to attempt to give any hints as to where it may be +looked for. It is, however, a very common butterfly in many continental +countries, and foreign specimens may be obtained from any dealer in +entomological wares for a few pence each. + +This rare British gem is illustrated in fig. 2 of Plate IV. Here it will +be seen that nearly the whole of the surface is covered with a rich +velvety purple brown, bordered with a black band containing blue spots; +and outside this is a border of white, finely dotted and streaked with +black. The continental specimens may be easily distinguished from the +genuine Britishers by a darker border with a decidedly yellow tinge. + +The eggs of this species are generally laid on the young leaves of the +willow (_Salix alba_), in the spring, by females that have hybernated, +but sometimes the nettle (_Urtica dioica_) and the birch (_Betula alba_) +are selected for the food of the larvae. + +The caterpillar is black and spiny, and has a row of seven rather large +reddish-brown spots on the back, commencing at the fifth segment. + +The chrysalis, like those of the other members of this family, is +angular and suspended by the 'tail.' The perfect insect appears in +August, and may be seen from that month till October. + + +_The Red Admiral_ (_Vanessa Atalanta_) + +There seems to be a tendency with many to under-estimate the beauty of +certain natural objects because they happen to be so very common, and +this is particularly the case with some of our most familiar +butterflies. The beautiful Red Admiral (Plate IV, fig. 3) may possibly +suffer in this respect; for, not only is it one of the commonest of our +butterflies, but it fearlessly hovers among the flowers of our gardens, +often venturing into the very heart of thickly populated towns. + +The bright scarlet bands and white blotches of this gorgeous insect +stand out boldly on the rich velvety black ground of the wings, and the +additional touches of blue in the anal angles of the hind wings add to +the effect. The under side of the fore wings is somewhat similar to the +upper surface, but is relieved by brown and blue; and this side of the +hind wings presents most beautiful and indescribable blendings of +various shades of brown, grey, and pink. The female may be +distinguished by the presence of a small white spot on the scarlet band +of the fore wing. + +The eggs are deposited singly on the nettle (_Urtica dioica_) in spring +by females that have hybernated through the winter. + +The caterpillar always feeds under the cover of a tent made by drawing +leaves together. It is spiny, and its colour is usually a greenish or +yellowish grey, spotted with black, and striped along the sides with +white or yellow. When fully grown it bites the stem of the nettle nearly +through a few inches from the top, so that the upper part of the plant +bends over the withers. It then constructs a commodious tent by binding +the leaves of this drooping portion together, and suspends itself from +the roof of this strange home to undergo its metamorphoses. + +The change to the chrysalis state takes place in July or August, and the +perfect insect may be seen during August, September, and October in +almost every part of the British Isles. + + +_The Painted Lady_ (_Vanessa Cardui_) + +Although the time of appearance of this butterfly generally corresponds +with that of the last species, yet it is exceedingly variable, so much +so that it is impossible to give any fixed period as its season. It is, +moreover, very capricious with regard to its localities and its numbers. +Sometimes it will turn up unexpectedly in positive abundance in certain +localities where previously it had been a mere straggler; and then, for +some unaccountable reason, become comparatively scarce for several +successive seasons. + +The upper surface of this beauty (Plate IV, fig. 4) is adorned with pale +red, orange, and black, and with five white spots near the tip of each +fore wing. The under side of the fore wings is marked something like the +upper, but much of the black is replaced by shades of brown. The hind +wings are beautifully variegated beneath with greys and browns, and have +a row of eye-like spots near the hind margin. + +The eggs of this butterfly are laid singly on various species of +thistles, particularly the common field thistle (_Cnicus arvensis_), +generally in the month of June. + +The caterpillar, which is black above and red beneath, with yellowish +stripes along the back and sides, feeds under the cover of a silken web +which it constructs among the leaves. It is full grown in July or +August, when it suspends itself after the manner of the other Vanessas +previous to undergoing its changes. + +The chrysalis is angular, coloured with brown and grey, and adorned with +brilliant gold spots. + +The perfect insect may be seen at large throughout late summer and the +autumn, and the eggs are laid by females that survive the winter. + + +_The White Admiral_ (_Limenitis Sibylla_) + +The White Admiral (Plate IV, fig. 5) is neither so pretty nor so common +as its red namesake, but it is nevertheless a fine insect, although the +chief beauty is reserved for the under surface. Above, the ground colour +is a very dark rusty brown, relieved by bands and spots of white. The +under surface is beautifully marked with silvery blue, bright orange +brown, and white, the latter being arranged just like the corresponding +colour on the upper side. + +It will be observed that this butterfly does not belong to the _Vanessa_ +genus; so, while we may look for _family_ resemblances, we shall observe +a few features in which it differs from the preceding species. + +It is not by any means abundant, being unknown in Scotland and Ireland, +and confined in England almost exclusively to the oak woods of the +south, where its food plant--the honeysuckle (_Lonicera +Periclymenum_)--abounds. Here it may be seen during July, gracefully +sailing among the trees and across the open spaces. + +The caterpillar is very different from those of the Vanessas. Its colour +is dark green, with a narrow white stripe along each side. There are +very conspicuous branched spines on the third and two following +segments, also on the eleventh and twelfth; and smaller spines on most +of the others. All the spines are of a brownish colour, with pink tips. +While it is yet very small it prepares its winter quarters by bending +round the remains of a leaf on which it has been feeding, securing the +edges by silken threads, and then binding it to the stem of the plant. +Soon after, the petiole becomes detached from the stem, and the little +caterpillar then rests suspended in its snug swinging cradle, where it +remains perfectly secure till the following April, when the warm sun +calls it out to feed on the opening leaves. It continues at this till +about the beginning of June, and then changes to a beautiful angular and +eared chrysalis, of a bright green colour, marked with brown, and having +brilliant silvery spots and streaks. + + +Family--APATURIDAE + +_The Purple Emperor_ (_Apatura Iris_) + +This grand insect is the only British member of its family, and richly +deserves its popular title. The male, which is figured on Plate V (fig. +1), exhibits a most gorgeous imperial purple, which is reflected at +certain angles only from the upper surface of his large and powerful +wings. His flight is lofty and vigorous, and among the topmost branches +of majestic oaks, where he defies the efforts of would-be capturers. +Unlike our other butterflies, he is also a very quarrelsome creature, +and will not hesitate to fiercely attack a brother Emperor who dares +approach the branch he has selected for his throne. + +Many attempts have been made to capture this prized creature by means of +a large net mounted on the end of a pole twenty or thirty feet in +length, but the wielding of such a cumbersome implement against so +powerful an insect is no mean task, and but few fall a prey to such a +snare. But it so happens that this imperial personage has a very +depraved appetite, the indulgence in which has often brought him to +ruin. Instead of searching out the sweets so bounteously supplied by the +blossoms that are so attractive to other lepidopterous insects, he +delights in sipping the waters of the filthiest puddles, and imbibing +the odoriferous moisture of dung and the decomposing carcases of +animals. So deeply seated is this depravity of taste that the Emperor +may be netted with ease while indulging in his sumptuous feast, and is +even to be taken at times with the fingers. + +The knowledge of this peculiarity of the imperial palate has led +entomologists to abandon the awkward net, and to bait the woods with +viands that alone can entice his highness from his lofty seat; and many +a splendid specimen has been easily captured while enjoying the +luxurious juice of a dead cat, stoat, or rabbit, or of a seething mass +of pig's dung. + +The female is larger than her mate, and does not display the beautiful +purple reflections that adorn the male. She is very different, too, in +her habits, for she sits nearly all day on high branches of trees, +giving her attention to the graver duties of an imperial mother, and is +consequently but seldom seem. She lays her eggs in July on the sallow +(_Salix Caprea_) or the poplar (_Populus_), and in less than a fortnight +the young caterpillars are hatched. They feed on till the leaves are +falling, and then fix themselves by their claspers to a silken carpet +which they construct on a twig. Here they remain, exposed to all the +wintry blasts and frosts, till the new leaves are out in the spring, +when they again commence feeding, and continue to do so till they are +full grown--in May or June. + +The under side of this species is shown in fig. 76, in which will also +be observed the eye-like spots of the fore wings which have given rise +to its specific name (_Iris_). + +The caterpillar (Plate VIII, fig. 5) is a very peculiar creature. Its +body is green, with seven oblique yellowish stripes on each side, and it +has a pair of horns attached to its head. + +[Illustration: FIG. 76.--THE PURPLE EMPEROR--UNDER SIDE.] + +The chrysalis (Plate VIII, fig. 10) may be found in June, suspended to +the under side of a leaf. It is of an apple-green colour, and still +exhibits the oblique stripes which we observed in the caterpillar. + +This insect is not to be found in either Scotland or Ireland, but is +more or less abundant in many of the oak woods of the midland and +southern counties of England. Among the numerous favoured localities, we +may mention Colchester, Forest of Dean, Northamptonshire, Ipswich, +Huntingdonshire, Buckinghamshire, Epping, Lyndhurst, and the Isle of +Wight. + + + + +CHAPTER XIV + +_THE BROWNS AND HEATHS_ + + +Family--SATYRIDAE + +This family contains eleven British species, often spoken of +collectively as the 'Browns,' since in most of them the prevailing tints +are various shades of brown. They are decidedly dingy in comparison with +the beautiful butterflies we have been previously observing; but to this +statement we must allow one marked exception, for the family includes +the beautiful Marbled White, which stands out prominently among its +fellows for brilliancy and boldness of colour. + +The caterpillars of the 'Satyrs' have no spines, but their bodies are +covered with very minute hair-bearing warts that give them a soft +velvety appearance. The hinder extremity tapers off considerably, and +terminates in two points. + +The chrysalides are not angular like those of the preceding species, and +though generally suspended by the tail, are sometimes found quite free +among leaves and grasses on the ground. + +The perfect insects are rather feeble fliers, and generally take so +little notice of intruders that they are easily caught in the hand. +Their wings are devoid of angles, and they have only four perfectly +developed legs. + + +_The Marbled White_ (_Melanargia Galatea_) + +Our first member of this family is the exception to which we have +already alluded as a relief to the general dinginess of the 'Browns.' +Its colours above are cream and black, arranged as shown in Plate V, +fig. 2. The under side (fig. 77) is marked with white, black, and +greenish grey, with a row of eye-like spots parallel with the hind +margin of the hind wings. + +This butterfly is not known in Scotland or Ireland, nor is it to be +found in several of the northern counties of England. Its chief haunts +are the waste cliffy grounds of the southern and some of the midland +counties of England, where it is usually restricted to certain small +districts. In some places it is really a common insect, and among these +may be mentioned Brighton, Horsham, Dover, Folkestone, Margate, +Gravesend, New Forest, parts of Gloucestershire, Cambridgeshire, and +Devonshire, also in the Isle of Wight and South Wales. + +[Illustration: FIG. 77.--THE MARBLED WHITE--UNDER SIDE.] + +The perfect insect is out in July, during which month the eggs are +deposited on various grasses, or indiscriminately on leaves and stems in +grassy spots. + +The caterpillar feeds on grasses; and, being still small at the end of +the autumn, hybernates during the winter among the stems of grass. It +feeds again in April, and is fully grown by the end of May. Its colour +is a dull green or brownish, with a darker stripe down the back, and +lighter stripes along the sides. Its spiracles are black. + +The chrysalis is pale brown, marked with lines of a slightly darker +shade. It may be found among grass stems, without any attachment, during +the month of June. + + +_The Small Ringlet_ (_Erebia Epiphron_) + +On account of the very limited range of this butterfly, only those who +have the opportunity of visiting its haunts can have any practical +acquaintance with its natural history. It is almost exclusively confined +to the lake district in England, to a few mountainous localities in +Scotland, and to one or two similar localities in Ireland. Its strong +partiality for elevated situations has earned for it the popular name of +Mountain Ringlet. + +The colour of the upper surface (Plate V, fig. 3) is a dark brown, with +a broad band of rusty brown, parallel with the hind margin of each wing, +and broken by the wing rays. Each division of these bands has often a +black central spot, but frequently these are entirely absent. The +colouring of the under side is very similar but less defined, and the +rusty spots of the hind wings are very small. + +The butterfly is out in June and July. The caterpillars, which are +green, with white stripes along the sides, feed on various grasses. They +hybernate during the winter, and change to the chrysalis state in the +following May or June. + + +_The Northern Brown_ (_Erebia AEthiops_) + +The colour of this species (Plate V, fig. 4) is a rich dark brown, with +rust-coloured and black spotted bands arranged something like those of +the last. The markings, however, are very variable. There are usually +four black spots on the band of the fore wings, but the first two of +these are always united, and centred with white. The third is often very +small or entirely wanting. + +The under side of the fore wings is marked something like the upper, but +the hind wings on this side are grey, with two broad bands of a darker +colour. + +As its popular name implies, this butterfly is a northerner. It is +common in Scotland, where it flies in elevated spots. In England it is +confined to the mountainous districts of the north. + +The perfect insect is at large in July and August, during which time the +eggs are deposited on various grasses or on low-growing herbage in +grassy spots. + +The caterpillar is of a brown colour, and has a narrow black stripe down +the middle of the back, and two other stripes, lighter than the ground +colour, one on each side. At about the end of June it turns to a +chrysalis of a brownish colour. + +The food plants of this species include a number of common grasses. + + +_The Speckled Wood or Wood Argus_ (_Pararge Egeria_) + +Most of our butterflies delight in the hot sun, and are to be seen on +the wing only when it is shining brightly. This fact is particularly +noticeable on a bright day with occasional heavy clouds. While the sun's +rays are pouring uninterruptedly on the landscape, numbers of these +light-lovers are to be observed flitting about; but when the dense +shadow of a passing cloud creeps over the ground they rapidly disappear +from view, having settled down to rest on leaves and stems. Then, as +soon as the shadow passes away, the air is again enlivened with their +sports and flittings. + +The Wood Argus is a marked exception to this rule. It delights in the +cool shade of the narrow paths of woods, where it slowly flies up and +down the lonely footpath, taking but little heed of strangers that +intrude on its haunts, and seldom venturing into the full blaze of the +sun unless pursued. Even on dull days it continues its solitary flight, +and may even be seen on the wing while a soft rain is bathing the +dripping foliage. + +The upper surface of this pretty butterfly is shown on Plate V, fig. 5, +and the under side in the accompanying woodcut. Both sides are prettily +marked with various shades of brown and buff, and adorned with +white-centred dark eye-spots which have earned for it the name of Argus. + +[Illustration: FIG. 78.--THE WOOD ARGUS--UNDER SIDE.] + +It first appears on the wing in April, and may be seen from this month +continuously to the end of August. + +The food plants probably consist of many species of grasses, the +cock's-foot (_Dactylis glomerata_) and couch grass (_Agropyron repens_) +being among the number, and the eggs are laid on or in the neighbourhood +of these during the summer months. + +The caterpillar of this species is of a dull greenish or brownish +colour, and it has two whitish stripes (sometimes three) down the middle +of the back, and similar stripes along each side. It hybernates during +the winter, and is full grown in March, when it changes to a dull green +or brownish chrysalis, which is streaked with black, and has a few white +dots on the back. + +It has been stated that the butterfly is on the wing from April to +August, and, according to some authorities, there are no less than three +broods during this time, following each other in rapid succession. It is +common throughout England and Ireland, and is known in parts of +Scotland. + + +_The Wall Butterfly_ (_Pararge Megaera_) + +Belonging to the same genus is another very familiar butterfly--the +Wall--which receives its popular title from its peculiar habit of +frequently resting on walls and stony banks. It is one of the first, if +not _the_ first, to take to the wing in the morning, and is generally +the last to seek its hiding place in the evening. I have seen it +actively flying about during August, as early as 7.30 in the morning, +and found it still flitting from one spot to another along the western +side of a wall as late as 8 in the evening, as if in search of a +convenient shelter for the fast approaching night. + +This pretty 'Brown' must be familiar to the reader, and the coloured +drawing on Plate V (fig. 6) will at once serve for purposes of +identification without the necessity of a wordy description. It may be +mentioned, however, that the male (the sex figured) is smaller than the +female, and is further distinguished by a broad dark oblique band +passing across each fore wing. + +The Wall is a double-brooded butterfly, the first brood appearing in +May, and the second in August. The caterpillars which produce the latter +may be found on the cock's foot (_Dactylis glomerata_) and other grasses +in June, while those of the former are hybernators; and the chrysalides +of the two broods may be found in April and July respectively. + +The colour of the caterpillar is green, with a slightly darker stripe +down the middle of the back, a pale stripe along each side, and another +similar stripe about midway between these two. + +The chrysalis is green with the exception of the more prominent parts of +its surface, which are almost white. + +This species is very common in almost every locality in Britain. + + +_The Grayling_ (_Satyrus Semele_) + +The Grayling is the largest of our 'Browns,' and, although a powerful +flier, it seldom takes long flights. The female, which is shown in fig. +7, Plate V, is really a beautiful creature, the light markings of which +stand out in bold contrast with the deep brown ground colour; but the +male is comparatively dingy, there being much less contrast between the +ground and the markings. He is also smaller than his mate. + +The under side of both sexes is similar (fig. 79), the pattern of the +fore wings being much like that of the other side, but considerably +lighter, and the hind wings are beautifully marbled with various greys +and browns. + +[Illustration: FIG. 79.--THE GRAYLING--UNDER SIDE.] + +This species is not nearly so common as the two preceding, but it is +very widely distributed, and is exceedingly abundant in some parts. On +some of the heathery cliffs and downs of the south and south-west coasts +it is so plentiful that the butterflies are started into the air at +almost every step, for it seldom flies except when disturbed. It is a +common insect in Ireland, and also in parts of Scotland. + +The caterpillar is a hybernator, and may be found feeding on grasses in +the autumn and the spring. It changes to the chrysalis in June, and the +perfect insect is on the wing from June to the beginning of September. + +The colour of the caterpillar is pinkish drab above, and greenish drab +beneath. A dark brown stripe, edged with a lighter colour, passes down +the middle of the back, and a dark line on each side. It changes to a +dark reddish-brown chrysalis on the surface of the ground, or, according +to some observers, a little beneath the surface. + + +_The Meadow Brown_ (_Epinephele Janira_) + +Although this very common butterfly is usually considered to be the +dingiest of its family, yet it must be admitted that the colour of a +freshly emerged specimen is really very rich. + +The male is of a dark brown colour, with an indistinct patch of a +lighter tawny brown near the outer margin of the fore wings, and a +white-centred black eye-spot near the costal angle of the same wings. +The female (Plate V, fig. 8) is of a lighter colour, the eye-spot on her +fore wings is larger and far more conspicuous, and an irregular patch of +light orange brown occupies a large area of each of the same wings. She +is, moreover, larger than her mate, and in every way a more attractive +insect. + +The Meadow Brown abounds everywhere, from June to September, and may be +seen on grass land and waste grounds where other butterflies are seldom +found. + +The caterpillar is green, and is rendered slightly rough by a number of +minute warts. There is also a white stripe on each side. It feeds on +various grasses in the autumn, hybernates during the winter, and is full +grown in May. + +The chrysalis is apple green, spotted with a lighter green, and has +several black markings. + + +_The Large Heath_ (_Epinephele Tithonus_) + +This butterfly is sometimes called the 'Small Meadow Brown,' and is +certainly much like the last species, both in colouring and habits. + +The fore wings of the male (Plate V, fig. 9) are light orange brown, +bordered with dark brown, and having a broad patch of the same across +the middle; and near the costal angle is a round black spot with two +white dots. The hind wings are dark brown with a patch of light orange +brown near the centre, and a small eye-spot near the anal angle. The +female is exactly similar, except that she does not possess the broad +bar on the fore wings. + +[Illustration: FIG. 80.--THE LARGE HEATH--UNDER SIDE.] + +The under side is shown in fig. 80, and is coloured with various shades +of brown. + +This is a very common butterfly, and may be seen during July in most +English counties, also in the south of Scotland, and in a few localities +in the south of Ireland. It frequents meadows, heaths, downs, and lanes, +like _Janira_, but is not nearly so abundant as that species. + +The young caterpillar is hatched in August, and is still very small when +it seeks its winter shelter among the stems of grasses. It resumes +feeding in the following May, and is full grown towards the end of June. +Its colour is very variable--pale green, olive green, or dull brown, +with five longitudinal stripes at about equal distances from each other. +These consist of a dark one down the middle of the back, a pale line +along each side, and another pale line midway between these. + +The chrysalis may be found at the end of June, attached by the tail to +blades of grass. It is of a very light colour, almost white, but adorned +with numerous black lines and patches. + + +_The Ringlet_ (_Epinephele Hyperanthus_) + +This is another rather plainly dressed insect, though somewhat prettily +adorned on the under side. The upper surface is of a very deep sepia +brown, almost black, with a few indistinct black eye-like spots near the +margins. The under side (Plate V, fig. 10) is of a lighter umber brown, +with corresponding eye-spots generally very conspicuous. These spots are +black, with white centres, and generally surrounded by light rings. They +are subject, however, to considerable variation. Those on the upper +surface are sometimes quite absent in the male, but are nearly always +readily perceptible in the female. On the under side, too, they are +occasionally quite absent, while in other varieties they are minute +white-centred dots, without any surrounding light ring. Our coloured +drawing represents the most usual form. + +[Illustration: FIG. 81.--THE RINGLET--UPPER SIDE.] + +The favourite haunts of the Ringlet are the borders of woods, and the +sheltered sides of flowery hedgerows. It is not so widely distributed as +some of the common 'Browns,' but is usually very abundant where it +occurs, sometimes appearing in such numbers that several may be taken +with a single stroke of the net. It does not seem to be a frequenter of +Scotland, and is known in Ireland only in the south. Its head quarters +are the southern and south-midland counties of England. + +The eggs are laid in July on various grasses, on which the young +caterpillars feed from about the middle of August till the cold weather +sets in. They hybernate at the roots of the grasses till the beginning +of the following May, and change to the chrysalis state about the middle +of June, suspending themselves to grass blades by means of their anal +hooks. + +The colour of the caterpillar is dull green or brown, and is marked with +five longitudinal stripes much like those of the Large Heath. + +The chrysalis is pale brown, spotted and striped with a darker shade of +the same colour. + + +_The Marsh Ringlet_ (_Caenonympha Typhon_) + +The upper surface of this butterfly is shown in the first figure of +Plate VI, and the under side in the accompanying woodcut; but it must be +remembered that the species is a very variable one, so much so that it +is almost impossible to give anything like a short and, at the same +time, a satisfactory description. The female may usually be +distinguished by a pale patch across the middle of the fore wings; and +the eye spots of the same wings, always more or less indistinct when +present, are sometimes entirely wanting. The markings of the under side +are even more variable, the transverse bars and the eye spots being +often particularly conspicuous, and at other times hardly discernible. + +[Illustration: FIG. 82.--THE MARSH RINGLET--UNDER SIDE.] + +This is generally spoken of as a northerner, its chief localities being +in the mountainous parts of Scotland and the elevated districts of the +north of England, but in Ireland it extends to the southern ranges. Its +haunts are elevated moors and marshy heaths, where its food plant--the +beak-rush (_Rhyncospora alba_)--abounds, and it is on the wing from the +end of June to August or September. + +The caterpillar is green, with five longitudinal stripes--one dark one, +bordered with yellow, down the middle of the back, and two pale yellow +ones on each side. It is a hybernator, and is full grown about the end +of May, when it suspends itself by the hindmost claspers to a silken +carpet, and changes to a green chrysalis with pale brown wing cases. + + +_The Small Heath_ (_Caenonympha Pamphilus_) + +The last member of the family _Satyridae_ is the well-known Small Heath, +that may be seen almost all over the British Isles on heaths, meadows +and moors, from May to September. + +The upper surface of this butterfly (Plate VI, fig. 2) is a tawny +yellow, with a dark brown border, and a spot of the same dark tint near +the tip of each fore wing. The under side is much like that of the last +species, but there are no eye spots on the hind wings. + +The eggs of the first brood are laid during May and June on the various +grasses on which the caterpillar feeds. + +The caterpillars that emerge from these are fully grown in July or early +August, and go through their changes during the latter month; but the +later ones hybernate during the winter, and are not full fed till the +following May. + +The colour of the larva is pale apple green, with a wide darker stripe +down the back, two others along the sides, and two more between the +latter and the dorsal stripe. All these five stripes are bordered with a +whitish colour. + +The chrysalis is bright apple green, dotted with white, and the wing +cases are striped with a purple-brown line edged with white. + + + + +CHAPTER XV + +_THE HAIRSTREAKS, COPPERS AND BLUES_ + + +Family--LYCAENIDAE + +This is a large family, including as it does no less than nineteen of +the British species. These are all of small size, and are characterised +by their short and jerky flights. They seldom rise much above the +ground, and are consequently very easily caught. + +The caterpillars of this family have all short and rather thick bodies, +shaped very much like that of the wood louse--flattened beneath and very +convex above. + +The chrysalides are generally attached by the 'tail,' and further +secured by a silken cord round the body, as we have already observed in +the case of the _Pieridae_. + +The perfect insects differ from the preceding species in that all six +legs are perfectly developed and adapted for walking. + +There are only three genera in this large family: + + 1. _Thecla_--The Hairstreaks, with 'tailed' wings. + 2. _Polyommatus_--The 'Coppers.' + 3. _Lycaena_--The 'Blues,' with wings either blue or brown. + + +_The Brown Hairstreak_ (_Thecla Betulae_) + +The five Hairstreaks which constitute the genus _Thecla_ are all pretty +insects, characterised by hair-like streaks on the under surface. + +_Betulae_ is the largest of these. Its upper surface is of a deep brown +colour, with orange-brown marks at the anal angles of the hind wings, +and, in the female, a large patch of orange on the fore wings. The under +side (Plate VI, fig. 3) is orange brown, much lighter in the male than +in the female. On the fore wings are two white lines, the inner one of +which is indistinct; and on the hind wings are two others, the outer one +being longer and more distinct than the inner. + +This butterfly is by no means an abundant insect, though it is widely +distributed, and in some places plentiful. Its chief haunts are woods, +and we may mention among its favoured localities Epping Forest, Monk's +Wood in Cambridgeshire, the wooded parts of South Devon and Dorset, New +Forest, Colchester, and Peterborough. + +[Illustration: FIG. 83.--THE BROWN HAIRSTREAK--MALE.] + +The perfect insect is on the wing from July to October, and the eggs are +deposited in the autumn on the twigs of its food plant--the blackthorn +(_Prunus spinosa_). These do not hatch till the following spring. Toward +the end of June the caterpillar is fully fed. + +The colour of the caterpillar is light green, with two white stripes +down the back, and two others along the sides. There are also two small +oblique whitish lines on each side of each segment. + +The chrysalis is smooth, and of a pale brown colour. + + +_The Black Hairstreak, or White-letter Hairstreak_ (_Thecla W-album_) + +The first of the above two popular names has been applied to this +species on account of the very deep brown colour of the upper side, +which colour is often a near approach to black. The second is due to the +W-shaped bend of the white streak of the hind wings. The ground colour +of the under side (Plate VI, fig. 4) is greyish brown, with a bright +orange band, spotted with black near the hind margin of the hind wings. + +[Illustration: FIG. 84.--THE WHITE-LETTER HAIRSTREAK.] + +_W-album_ is a somewhat rare insect, but is occasionally seen in plenty +in a few localities, Cambridgeshire, Berkshire, Epping, Colchester and +Suffolk being among its chief resorts. It is out on the wing in July, +and should be looked for in wooded country where the common elm (_Ulmus +campestris_) and the wych elm (_U. montana_), its food plants, exist. + +The eggs are laid on the twigs of these trees late in the summer, and +the young caterpillars do not appear till the following spring. The +chrysalis may be found attached to an elm twig or leaf about the end of +June. + +The caterpillar is pale green. The ridges along the back are tinged with +yellow, and there are two fine oblique white lines on each side of each +segment. + + +_The Dark Hairstreak_ (_Thecla Pruni_) + +The upper side of this butterfly is very much like that of _W-album_, +but it may be distinguished by the presence of a few orange spots near +the anal angle of the hind wings. The colouring of the under side (Plate +VI, fig. 5) is also very similar, except that the white lines of the +wings are thinner and less distinct than in the last species, and do not +exhibit the W-shaped bend. The orange band of this surface is bordered +on each side with a row of black spots, each of which is touched with a +bluish white or a metallic blue. + +This insect is not by any means common, but has been seen in +considerable numbers in certain localities. It is not found in either +Scotland or Ireland, and its chief haunts in England seem to be in +Huntingdonshire, Cambridgeshire and Northamptonshire. It frequents +wooded country, and flies during June and July. + +The eggs are laid late in the summer on the twigs of the blackthorn +(_Prunus spinosa_), and are not hatched till the following spring. + +The caterpillar, which is pale green, with rows of yellow spots, may be +found in May. + + +_The Purple Hairstreak_ (_Thecla Quercus_) + +This pretty butterfly, by far the commonest of the Hairstreaks, though +comparatively very small, reminds one forcibly of the noble Purple +Emperor. Its haunts are the same oak woods, and its upper surface, +though only a dull dark brown in certain lights, exhibits the same +imperial purple reflections when viewed at certain angles. The purple of +the male extends over the whole of the wings, but that of the female is +confined to a V-shaped patch at the base of the fore wings. In the +latter case, however, the purple is much richer than in the male sex. + +The under side (Plate VI, fig. 6) is coloured with a delicate grey +ground, adorned with a white streak on each wing, and a couple of orange +spots near the anal angle of the hind wings. + +This species is very widely distributed, being common in oak woods in +most parts of England, and also in many parts of Scotland and Ireland. +It flies around the branches of the trees, and often disappoints the +collector by keeping far beyond the reach of his net. + +[Illustration: FIG. 85.--THE PURPLE HAIRSTREAK--MALE.] + +Those in search of this pretty insect should ramble in oak woods, +preferably in the south of England, during July and August. The eggs may +be found glued to the twigs throughout the winter, and the larvae may be +beaten from the branches of the oak in June. + +The colour of the caterpillar is brownish or pinkish green, with a row +of V-shaped marks down the back. + +The chrysalis is of a brown colour, short and thick, and may be found +either attached to oak leaves, or under the surface of the earth at the +foot of the tree on which the caterpillar fed. + + +_The Green Hairstreak_ (_Thecla Rubi_) + +Next to _Quercus_, this is the most plentiful of the genus. It frequents +woods and heaths in nearly every county in England, and is also found in +parts of Scotland and Ireland. It is peculiar among British butterflies +as being the only one that exhibits a bright green colour. It also +differs from the other Hairstreaks in two important particulars, for the +hind wings, though angled at the hind margin, are not 'tailed,' and the +characteristic hairstreak which gives the popular name to the genus is +here represented only by a series of white dots across the wings, or, in +some cases, by one or two dots on the hind wings only. + +[Illustration: FIG. 86.--THE GREEN HAIRSTREAK.] + +The upper side is dark brown, displaying metallic reflections when +viewed in a strong light. The under side is represented in fig. 7 of +Plate VI. + +The chief food plants of this species are the bramble (_Rubus +fruticosus_), the birch (_Betula alba_), and the broom (_Cytisus +scoparius_). + +The perfect insect flies in May and June, and the eggs are deposited +during the latter month on the above plants. The caterpillars are full +fed in July, and change to the chrysalis state towards the end of the +summer. + +The colour of the caterpillar is pale green, with a yellow stripe and +several white oblique lines along the sides, also a yellowish stripe +down the back. + +The chrysalis is short and thick, and of a dark brown colour. + + +_The Large Copper_ (_Polyommatus Dispar_) + +Our next genus contains only two British species. The first of +these--the Large Copper--was once a common insect at Whittlesea in +Cambridgeshire, and in some of the fens of Huntingdonshire, but is now +feared to be quite extinct, as none have been seen for many years. The +last capture was made in 1847 in Huntingdonshire. However, it _may_ turn +up again; and even if it does not, it would be a pity to allow the +memory of so fine an insect to die out; so we find room to figure it +(Plate VI, fig. 8), and append a few remarks. + +There is a very great difference between the male and the female. The +former is of a brilliant copper hue, and all the wings have a black +margin and a black streak near the middle. The female is larger; and the +coppery colour is much redder. The black border of the fore wings is +wider, and there are also several large black spots on these wings. The +hind wings are almost entirely covered with black, with the exception of +a broad coppery band near the hind margin. + +The food plant of the caterpillar appears to have been the water dock +(_Rumex Hydrolapathum_), on which the eggs were laid late in the summer. +It is probable that the caterpillar was a hybernator, seeking its winter +shelter while still very young; and it was full fed in June. + +Its colour was green, with a darker stripe of the same colour on the +back; and the chrysalis was attached by anal hooks and a cord round the +body. + + +_The Small Copper_ (_Polyommatus Phlaeas_) + +The only other British member of the genus _Polyommatus_--the Small +Copper--is one of the commonest of our butterflies. It may be found in +nearly all parts of the British Isles from April to September, more +particularly in April, June, _and_ August, for it is apparently triple +brooded. + +This brilliant and lively little insect is shown on Plate VI (fig. 9), +and, being so very familiar, needs no description. + +The caterpillar feeds on different species of dock--the broad-leaved +dock (_Rumex obtusifolius_), the fiddle dock (_R. pulcher_), the sorrel +(_R. acetosa_), and the sheep sorrel (_R. acetosella_); also on the +ragwort (_Senecio Jacobaea_). It is full fed about three weeks after +hatching, and then changes to a small and stout chrysalis, of a pale +brown colour, on the leaf of its food plant. + +The caterpillar itself is green, with a reddish line on the back and on +each side; and it glides over the surface of the leaves something after +the manner of a slug, without exhibiting any very apparent motion of its +short legs and claspers. + + +_The Tailed Blue_ (_Lycaena Baetica_) + +We now come to a genus containing no less than ten species of beautiful +little butterflies, known commonly as the 'Blues;' but one of them +exhibits no trace of the colour so characteristic of the group, although +it resembles the others in structure and habits. + +Our first example is the Tailed Blue, known also as the Pea-pod Argus. +The upper side of this insect (Plate VI, fig. 10) is of a dull smoke +colour, exhibiting purple-blue reflections, which are, in the female, +confined to distinct blotches on the bases of the wings, but in the male +are less noticeable, and extend over the whole surface. The hind margin +of the hind wings has a row of spots, more or less distinct, and much +more prominent in the female than in the male. The under side is +beautifully marked with bands of fawn and grey, and with two spots of +brilliant metallic green in the anal angle of the hind wings. + +[Illustration: FIG. 87.--THE TAILED BLUE--UNDER SIDE.] + +This butterfly abounds in the countries of South Europe, where the +caterpillar feeds on the pods of certain leguminous plants; but only a +few stragglers have been taken in England, so that its reputation as a +true Britisher is very uncertain. It is highly probable that the two or +three specimens caught on our south coast were blown over from the +Continent, and that the insect has never bred on this side of the +Channel. + + +_The Silver-studded Blue_ (_Lycaena AEgon_) + +The upper surface of the male (Plate VI, fig. 11) of this species is +purple blue, with a black border on the hind margins of all wings. The +female (fig. 12 of the same plate) is of a very dark smoky-brown colour, +often with a bluish tinge, and has generally a row of orange spots near +the hind margin of the hind wings. + +The under side of both sexes is similar, and is illustrated in the +accompanying woodcut. The ground colour is bluish grey, and is marked +with a number of black spots surrounded by light rings. Along the hind +margin of the hind wings is a row of orange spots, each bordered with +black on the inner side, and with a silvery blue on the outer. + +[Illustration: FIG. 88. THE SILVER-STUDDED BLUE--UNDER SIDE.] + +This insect appears in July, and is common in many dry, sandy, or chalky +spots in various parts of England, and also in a few localities in +Scotland and Ireland. It has been reported as abundant at Darlington and +in certain localities in Lancashire, but its head quarters are +undoubtedly the chalk downs and dry gravelly banks of the southern +counties. + +The caterpillar feeds on the bird's-foot (_Ornithopus perpusillus_), and +is full grown towards the end of June. Its colour is yellow or grey, +with a brown dorsal stripe, a white line on each side, and pale oblique +lines near the former. About the end of June it changes to a dull green +chrysalis, with projecting wing cases. + + +_The Brown Argus_ (_Lycaena Astrarche_) + +Neither male nor female of this species exhibits any trace of blue. The +upper surface, shown in fig. 13 of Plate VI, is coloured with a warm +brown, and all four wings have a row of orange spots near the hind +margin. The fore wings have also a central black spot. The under +surface, drawn on the same plate (fig. 14), is bluish grey, with a +border of orange spots on each hind margin as on the other side. There +are also numerous black spots in light rings, the arrangement of which +will be seen in the figure. + +Some species of butterflies and moths are so variable in their colouring +and markings that varieties have often been mistaken for distinct +species; and, in other cases, distinct species are sometimes so similar +in character that they are looked upon as identical. + +A butterfly that closely resembles the normal Brown Argus in many +points, and named _Artaxerxes_, has often been described as a distinct +species, but is now, I believe, recognised by most entomologists as a +constant variety of the present species. + +It differs from the normal type in having a _white_ instead of a _black_ +spot in the centre of the fore wings, and the border of orange spots is +often very indistinct. On the under side, too, instead of black spots in +white rings, it has white spots, with little or no trace of a black +centre. + +The ordinary Brown Argus is a southerner, and is particularly abundant +on the chalk downs of the south coast and the Isle of Wight, but +_Artaxerxes_ is to be found only in Scotland and the north of England; +and it is interesting to note that, between these northern and southern +districts, intermediate varieties are to be met with. + +Again, _Astrarche_ is a double-brooded butterfly, appearing on the wing +in May and August; while _Artaxerxes_ is single brooded, flying at +midsummer. This fact has lent support to the opinion that the two are +distinct species; but it must be remembered that several insects that +are single brooded in one country are double brooded in a warmer +climate. + +The caterpillar of _Astrarche_ feeds on the hemlock stork's-bill +(_Erodium cicutarium_). It is of a pale yellow colour, with a brownish +line on the back; and is full fed in April and July. + + +_The Common Blue_ (_Lycaena Icarus_) + +Although this pretty little butterfly is so common that it is almost +sure to be known to all who take any interest in insect life, yet it is +important to observe it carefully, since it is an easy matter to +confound it with other species of the same genus. + +The upper surfaces of the two sexes are very different, that of the male +(Plate VI, fig. 15) being a beautiful lilac blue; and that of the +female (Plate VI, fig. 16) a dark brown, powdered with blue at the bases +of the wings, and having _generally_ a border of orange spots, more or +less defined, on the hind margins of all wings. + +[Illustration: FIG. 89.--THE COMMON BLUE--UNDER SIDE.] + +The under side, shown in the accompanying woodcut, is ashy brown; warm +in the female, but paler in the male. The hind wings, and sometimes all +four, are bordered with orange spots; and this species may be +distinguished from _Astrarche_ by the presence of two black spots, in +white rings, near the base of the fore wings. + +There will be no need to name localities for this insect, as it is +abundant everywhere, frequenting meadows, heaths, and all waste places. +It is double brooded, and is on the wing continuously from May to +September, the first brood enduring from May to July, and the second +from July to the end of the warm weather. + +The caterpillar is green, with a dorsal line of a darker tint, and a row +of white spots on each side. It feeds on clover (_Trifolium pratense_ +and _T. repens_), bird's-foot (_Ornithopus perpusillus_), bird's-foot +trefoil (_Lotus corniculatus_), and the rest-harrow (_Ononis spinosa_). + +The chrysalis is short and rounded, of a dull green colour, tinged with +brown on the under surface. + + +_The Clifden Blue_ (_Lycaena Bellargus_) + +Our coloured representations of this beautiful blue (Plate VI, figs. 17 +and 18) show that here also there is a great difference between the male +and female. The former is a most lovely and brilliant sky blue, bordered +by a fine black line; and the latter is a dull dark brown, with a more +or less distinct border of orange spots, and the bases of the wings are +powdered with scales of a tint corresponding with those of the male. In +both sexes the fringe is very distinctly barred with dark brown. + +[Illustration: FIG. 90.--THE CLIFDEN BLUE--UNDER SIDE.] + +The under side (fig. 90) is similar in both sexes--greyish brown, with +a border of reddish spots, and a number of black spots in white rings, +the arrangement of which is here represented. + +The butterfly frequents chalky downs, chiefly in the south of England, +and seems to be unknown in Scotland and Ireland. The Isle of Wight, and +the chalky downs and banks of Sussex, Surrey, and Kent, are its +favourite localities; and even in these it is generally very local, +sometimes swarming on a grassy bank of no great extent, when the +surrounding neighbourhood, though apparently equally suitable to its +requirements, does not harbour a single specimen. It is on the wing in +May and June, and again in August. + +The caterpillar is green, with two rows of yellow streaks on the back, +and a yellow stripe on each side. It feeds on the Dutch clover +(_Trifolium repens_), horse-shoe vetch (_Hippocrepis comosa_), and +various other leguminous plants. + + +_The Chalk-Hill Blue_ (_Lycaena Corydon_) + +The male of this species (Plate VII, fig. 1) is readily to be +distinguished from all other members of the genus by its pale glossy +blue, but the female (fig. 2 of Plate VII) so closely resembles that of +_Bellargus_ that it is often a somewhat difficult matter to discriminate +between them. The following, however, are a few points worthy of +observation: The upper side of the female _Corydon_ has the bases of the +wings more or less sprinkled with the pale silky blue that characterises +the male; and the black bars of the fringe are _usually_ broader in +_Corydon_ than in _Bellargus_. The black-centred spots of the under side +are also usually more conspicuous in the former species than in the +latter. + +[Illustration: FIG. 91.--THE CHALK HILL BLUE--UNDER SIDE.] + +The difficulty of identification is increased by the fact that both +these butterflies frequent similar localities, and are often on the wing +at the same time; but although _Corydon_ is certainly a frequenter of +chalky districts, yet it is often found plentifully in districts far +removed from the chalk, notably at Arnside in Lancashire, and in Epping +Forest. + +The butterfly is out in June and July. The caterpillar is green, with +two rows of short yellow streaks on the back, and a yellow stripe on +each side. It feeds on the purple and Dutch clovers (_Trifolium +pratense_ and _T. repens_), bird's-foot trefoil (_Lotus corniculatus_), +horse-shoe vetch (_Hippocrepis comosa_), and lady's fingers (_Anthyllis +vulneraria_). + + +_The Holly Blue_ (_Lycaena Argiolus_) + +While all the other Blues delight to sport on low flowery banks in the +full blaze of the summer's sun, the Holly Blue prefers to flit among the +branches of trees, often many feet from the ground. The larva feeds on +the flowers of the holly (_Ilex Aquifolium_) in the spring, and on those +of the ivy (_Hedera Helix_) late in the summer; also on the alder +buckthorn (_Rhamnus Frangula_); and it is in localities where these grow +that we may find this lovely Blue sporting among the branches, or +resting on a leaf with its wings folded together, thus making itself +conspicuous among the dark foliage by exposing the pale silvery blue of +its under surface. + +The upper sides of both the male and female are shown on Plate VII +(figs. 3 and 4 respectively), where the beautiful lilac blue will be +seen to have a border of black, wider in the latter than in the former. + +[Illustration: FIG. 92.--THE HOLLY BLUE--UNDER SIDE.] + +The under surface is spotted with black, as shown in fig. 92, and has no +border of orange spots. + +This is a double-brooded butterfly, appearing first in April and May, +and then again in August. It is not at all uncommon in the south of +England, and extends northward as far as the Lake District, but is not +found in Scotland. It is generally distributed throughout Ireland. + +The caterpillar may be looked for in June and October. It is light +green, with a line of dark green down the back. + + +_The Mazarine Blue_ (_Lycaena Semiargus_) + +The male (Plate VII, fig. 5) is deep purple blue, with a narrow +dark-brown border, and the female (fig. 6 of the same plate) dark brown. +The under side of both sexes is light greyish-brown or drab, with a row +of black spots in white rings parallel with the hind margin of each +wing, and no reddish or orange spots. + +This pretty butterfly seems to have been plentiful in several localities +some years since, but has not been seen for a long time; and it is +probable that its reckless slaughter by those who catch all the pretty +butterflies they can secure either for ornament or for gain has caused +its name to be permanently removed from our list of natives. + +[Illustration: FIG. 93.--THE MAZARINE BLUE--UNDER SIDE.] + +It was formerly abundant in Dorset, Hereford, Glamorganshire, and near +Shirley, and was on the wing in June and July, but it disappeared from +our view before a full account of its life history had been prepared. + + +_The Small Blue_ (_Lycaena Minima_) + +We now come to the smallest of all British butterflies--a little insect +that measures less than one inch from tip to tip when its wings are +expanded. Its upper surface is of a dull and dark-brown colour, the +bases of the wings being dusted with blue in the case of the male. The +under side is pale drab, tinged with greenish blue at the bases of the +wings, and marked with black spots in light rings as shown in the +accompanying figure. The upper side is represented in fig. 7 of Plate +VII. + +[Illustration: FIG. 94.--THE SMALL BLUE--UNDER SIDE.] + +This butterfly is on the wing in May and June, and during the latter +month the eggs are deposited on the flowers of the lady's fingers +(_Anthyllis vulneraria_). + +The caterpillars are hatched in about a week, and commence feeding on +the calyx of the buds, and soon burrow into them till they are quite +concealed. + +The colour of the caterpillar is brownish, with a darker stripe on the +back, and a row of oblique brown streaks on each side. + +This species is widely distributed in England, and is plentiful in most +chalky and limestone districts. It is also found in parts of Scotland +and Ireland. + + +_The Large Blue_ (_Lycaena Arion_) + +The last of our Blues is the largest of the genus, and is, with the +exception of _Semiargus_, the rarest. It is a very local insect, +appearing in small numbers, during June and July, in parts of South +Devon, Gloucestershire, Northamptonshire, and a few other counties. + +[Illustration: FIG. 95.--THE LARGE BLUE--UNDER SIDE.] + +The colour of the upper side is a dark and rich blue, with a broad dark +border on the hind margins, and a group of black spots near the centre +of the fore wings. The under side (fig. 95) is of a pearly grey, without +any red spots, but having a double border of black spots, and also an +irregular row of black spots in white rings across the middle of each +wing. + +The caterpillar feeds on thyme (_Thymus Serpyllum_), on which plant the +eggs are laid singly, generally on the flower heads. + + + + +CHAPTER XVI + +_THE DUKE OF BURGUNDY AND THE SKIPPERS_ + + +Family--ERYCINIDAE + +_The Duke of Burgundy_ (_Nemeobius Lucina_) + +The family _Erycinidae_ has only one British representative, commonly +known as the Duke of Burgundy Fritillary, but although this butterfly +certainly resembles the Fritillaries in general appearance (see figs. 9 +and 10 of Plate VII), its habits and life history present many points of +difference from these. + +The upper side is chequered with black and tawny brown, the fringe is +white and barred with dark brown, and a row of tawny spots with black +centres border the hind margins. The under side has two rows of white +spots, one near the base, and the other across the centre of each wing. + +The male has only four legs adapted for walking, but the female has six. + +The butterfly is out in May and June, and frequents the paths and open +spaces of woods, chiefly in the south of England, but it has been taken +in some of the northern counties. + +The caterpillar (Plate VIII, fig. 6) is not spiny like those of the true +Fritillaries, but more closely resembles those of the Blues, being +somewhat of the form of a woodlouse. It is reddish brown, with tufts of +hair, black spiracles, and a dark line down the back. It feeds on the +primrose (_Primula acaulis_) and the cowslip (_P. veris_), and may be +found during June, July and August. + +When fully grown, the caterpillar secures itself to a leaf or stem by +means of its anal claspers and a silken cord round its body, and changes +to a short, thick, hairy and light-coloured chrysalis (Plate VIII, fig. +11), which is marked with several black spots. In this state it spends +the winter, and emerges early in the following summer. + + +Family--HESPERIIDAE--THE SKIPPERS + +This family contains eight small species, none of which are remarkable +for brilliancy of color. They are, nevertheless, very interesting +creatures, for they exhibit peculiarities of structure and habit that +render them singular among the butterflies, and seem to show a sort of +cousin relationship with the moths. They have thick bodies that remind +us somewhat of the _Noctuae_. Their heads are broad, so that the antennae, +which are slightly hooked at the tips, are rather wide apart at the +bases. When at rest, they neither press their wings together over their +back like the other butterflies, nor do they set them horizontally after +the manner of the moths, but seem to lay claim to an intermediate +position in the scale of Lepidopterous insects by holding them in a half +elevated position. Their flight, too, is not graceful like that of most +other butterflies, nor even so steady as that of the little flitting +blues, but brisk and erratic, and resembling the fitful motions of moths +disturbed from their slumberings at unwonted hours. Thus they have +earned their popular title of skippers from their habit of skipping +rather than flying from flower to flower. All the three pairs of legs of +these butterflies are fully developed for walking. + +The caterpillars have rather large heads, and their bodies taper from +the middle toward both extremities. Like the larvae of many moths, they +hide themselves in leaves which they have rolled and secured with silken +threads; and when about to change to the chrysalis state, they also spin +silken cocoons for their further protection. + + +_The Grizzled Skipper_ (_Syrichthus Malvae_) + +The ground color of this species is a very dark brown, relieved by a +number of square white spots arranged as shown in fig. 11 of Plate VII. +The fringe is wide, and barred with the same two colours, arranged +alternately. The pattern of the under side is similar, but the dark +brown of the upper surface is replaced by a lighter olive tint. + +The butterfly may be looked for in May in the open spaces of woods, +particularly in damp places. It is common all over England, and is found +also in the south of Scotland. + +The caterpillar is either green or brownish, with a darker dorsal stripe +of the same color, and two white lines on each side. It feeds on the +raspberry (_Rubus idaeus_), the bramble (_R. fruticosus_), and the +strawberry-leaved cinquefoil (_Potentilla Fragariastrum_), and is full +fed about the end of June. + +The chrysalis is greyish, spotted with black. It is rather elongated, +and without angles, but has a short and sharp projection extending +backwards from the 'tail.' + + +_The Dingy Skipper_ (_Nisoniades Tages_) + +Colour--a dingy brown, indistinctly barred and spotted with a darker +tint, and having a row of small white spots just inside the fringe of +the hind margins. Under side--a paler brown, with rows of small white +spots. + +This butterfly is common in all parts of England, and is found in a few +localities in Scotland and Ireland. It frequents dry banks, and is +particularly partial to the chalky districts of the south-eastern +counties. It is on the wing in May, and a second brood appears in lesser +numbers in August. + +The caterpillar is pale green, with two yellow stripes on each side, and +a row of black spots above each stripe. It feeds on the bird's-foot +trefoil (_Lotus corniculatus_), and may be found in June, and again in +September. + +The chrysalis (Plate VIII, fig. 12) is shaped something like that of the +last species, and is coloured green on the front segments, and a rose +red on the abdomen. + +The perfect insect is represented in fig. 12 of Plate VII. + + +_The Small Skipper_ (_Hesperia Thaumas_) + +In briefly describing the various British butterflies no mention has +been made, except in a few cases, of the shape of the wings, this matter +having been left to the reader's own observations of our illustrations. +We will, however, call attention to the somewhat square-cut form of the +wings of _Thaumas_ and the following species. + +The above-named butterfly (Plate VII, fig. 13) is a lively-looking +little insect, its wings being of a bright tawny orange colour, bordered +with black, beyond which is a light fringe. The male, which is the sex +figured, is distinguished from the female by an oblique black streak +across the middle of the front wings. The under side is orange, with a +decidedly greenish tinge. + +The butterfly is out in July, and is very abundant and widely +distributed. It lays its eggs on various grasses, particularly the +meadow soft-grass (_Holcus lanatus_). + +The caterpillar hybernates through the winter, and is full fed in the +following June, when it changes to a green chrysalis after spinning a +light silken cocoon among the blades of grass. The colour of the +caterpillar is green, with six longitudinal white stripes--two on the +back, and two on each side. + + +_The New Small Skipper_ (_Hesperia Lineola_) + +A few years since (1888) a butterfly was taken in one of our +south-eastern counties that closely resembled the well-known _Thaumas_ +(or _Linea_), but which turned out to be a species not previously known +in Britain. When, however, the distinguishing features of the new +butterfly were made known, several entomologists discovered that they +had already secured the new prize, but that, being ignorant of its +characteristics, they had placed it in their series over the label +_Thaumas_. + +Since the above date, this new insect (Plate VII, fig. 18), which is +named _Lineola_, has been taken in considerable numbers at Leigh, +Harwich, Southend, and near Shoeburyness in Suffolk, as well as in the +Fens of Huntingdonshire; and it is highly probable that it may turn up +in various other localities where it has not yet been observed. + +It appears on the wing about the first week of July, a little later than +_Thaumas_, but the two kindred species are often found flying together. + +The chief points by which we distinguish _Lineola_ from the last species +are these: The general appearance of the wings is a bit dingier than in +_Thaumas_; the inner portion of the hind wings is of a bright tawny +colour in _Thaumas_ but not in _Lineola_; the tips of the antennae are +yellow beneath in _Thaumas_, but black in _Lineola_; and the black +streak across the fore wings of the latter species is short and +generally broken. + +The eggs of _Lineola_ are laid at the end of July or beginning of August +on various grasses, chiefly the various species of _Triticum_, but do +not hatch till the following April. + +The larva is full fed about the end of June or beginning of July, and +then changes to a long yellowish-green chrysalis, from which the perfect +insect emerges in two or three weeks. + + +_The Lulworth Skipper_ (_Hesperia Actaeon_) + +Although this species is somewhat similar to the two preceding, it may +be readily distinguished by the heavy clouding of dull greenish brown +that almost covers the wings. The male, which is shown in fig. 14 of +Plate VII, has a black streak across the fore wings, and the female +possesses a semicircular row of tawny spots near the tip of the same +wings, and also a tawny streak near the centre. + +This is a very local species, having been found only in a few +localities. At Lulworth Cove and 'Burning Cliff' in Dorset it has been +met with in profusion. In Devon it frequents the rough ground near the +cliffs at Sidmouth and Torquay; and it has also been reported as +appearing at Stratford-on-Avon, Shenstone near Lichfield, and the +neighbourhoods of Swanage and Tyneham. + +One can scarcely hope to see this insect at large without making a +special trip to one of its favourite haunts, in which case a day should +be chosen toward the end of July or early in August. + + +_The Large Skipper_ (_Hesperia Sylvanus_) + +During May, June, and August this butterfly may be seen on grassy banks +in nearly every part of England, as well as in certain localities of +Scotland and Ireland. + +The wings are all of a bright orange-brown colour, with a narrow black +border, inside which is a broad shading of brown. The latter colour +usually completely covers the hind wings with the exception of about +half a dozen squarish spots; and the same colour, together with the dark +brown wing rays, breaks up the light ground of the fore wings, often +forming several squarish and triangular patches, most distinct near the +tips. The male (Plate VII, fig. 15) may be readily distinguished from +the female by the presence of a thick dark brown streak across the fore +wings. + +The under side of both sexes is pale tawny brown, with a greenish tinge; +and has several rather indistinct yellowish spots. + +The larva is of a dull green colour, with a dark line on the back. Its +upper surface is dotted with black, and there are white spots on the +under side of the tenth and eleventh segments. It feeds on several kinds +of grasses, some of its favourites being the meadow soft grass (_Holcus +lanatus_), the cock's-foot (_Dactylis glomerata_), and couch grass +(_Agropyron repens_). + + +_The Silver-spotted Skipper_ (_Hesperia Comma_) + +This species is very similar on the upper side to the last, except that +the squarish spots of both fore and hind wings are much paler and much +more distinct; and here, too, the male (Plate VII, fig. 16) is to be +distinguished from the female by a black streak crossing the front wings +obliquely. The under surface has a greenish tinge, more particularly on +the hind wings; and this side is conspicuously marked with a number of +_white_ square spots with sharp outlines, arranged as shown in fig. 96. + +[Illustration: FIG. 96.--THE SILVER-SPOTTED SKIPPER--UNDER SIDE.] + +Although common in some localities, this butterfly is not widely +distributed. It is confined to some of the southern and midland counties +of England, and is particularly partial to the chalk districts of the +south-east. On the chalk downs of Kent, Surrey, and Sussex it is +moderately common. It is on the wing during July and August. + +The caterpillar feeds on certain leguminous plants, among which are the +bird's-foot (_Ornithopus perpusillus_) and the bird's-foot trefoil +(_Lotus corniculatus_). + + +_The Chequered Skipper_ (_Carterocephalus Palaemon_) + +This is another local insect, more so even than the last, but it +sometimes appears in profusion in certain limited districts. Kettering, +Oundle in Northamptonshire, and Monk's Wood in Huntingdonshire are +places where it has been taken freely. It appears in June. + +The wings are chequered with very dark brown and orange. The fore wings +are bordered with small rounded yellow spots, and beside these there are +about nine very conspicuous yellow spots on the fore wing and three on +the hind wing. The arrangement of these markings may be seen in fig. 17 +of Plate VII. + +The caterpillar feeds on the greater plantain (_Plantago major_). + + + + +PART IV + +COMMON BRITISH MOTHS + +CHAPTER XVII + +_SPHINGES_ + + +We have already observed the chief features by which we are able to +distinguish between butterflies and moths (page 56), so we shall devote +the present division to a description of the characteristics and life +histories of some of the latter insects. + +The number of British butterflies is so limited that space could be +found for a brief description of every species, but with moths the case +is very different. There are about two thousand known British species of +this division of the Lepidoptera, and every year adds some newly +discovered insects to this long list; we shall therefore have to content +ourselves with making a selection of these for individual mention. + +In doing this I shall endeavour to provide the young entomologist with a +fairly representative list--one that will enable him to become more or +less intimately acquainted with all the principal divisions of the +_Heterocera_; and his attention will be drawn especially to many which +may be described as 'common' or 'generally distributed,' so that during +his first few seasons at collecting he may be enabled to identify and +study a fair proportion of his captures. Occasionally, however, one of +the rarer species will be described in order to illustrate some striking +characteristic. + +We shall commence with the tribe of _Sphinges_ or _Hawk Moths_. + +This group consists of three families--the _Sphingidae_, including the +largest of the 'Hawks,' and the 'Bee Hawks,' the _Sesiidae_ or +'Clearwings,' and the _Zygaenidae_, including the 'Foresters' and the +'Burnets'--numbering in all about forty species. + + +Family--SPHINGIDAE + +This family is named from a fancied resemblance of the larvae to the +celebrated Egyptian sphinx. The perfect insects have very thick bodies, +generally tapering toward the tail, and their wings are rather narrow in +proportion to the length, but are exceedingly powerful, and the flight +is, with one or two exceptions, very rapid. The antennae terminate in a +small and thin hook. + +Most of these insects fly at dusk, but a few delight in the brightness +and heat of the midday sun. In either case the velocity of their flight +is generally so great that it is a difficult matter to follow them with +the eye, and a still more difficult matter to secure the insects in the +net; consequently, the best way to study them is to search out the larvae +on their food plants, and rear them till they attain their perfect form. + +The larvae of the _Sphingidae_ are large and smooth, and most of them have +a horn projecting from the top of the last segment but one. They all +undergo their metamorphoses under the surface of the ground. + + +_The Death's-Head Hawk_ (_Acherontia Atropos_) + +Our first example of the Sphinges is the beautiful Death's-Head Hawk +Moth--an insect that often attains a breadth of five inches from tip to +tip when the wings are fully expanded. Its popular title has been +applied on account of the peculiar markings of the thorax, which are +said to resemble a human skull; and this feature has certainly some +connection with the superstitious beliefs of ignorant country folk +concerning this moth. But this characteristic is probably not the only +one that has caused the creature to be regarded with superstitious +alarm. Both its superior dimensions and nocturnal habits serve to +intensify the unfounded fear; but, what is particularly striking and +unique about it is its power of uttering a squeaking sound, which it +does when disturbed. Even the earlier stages of the insect possess this +strange power. The caterpillar makes a peculiar snapping noise when +irritated, and the chrysalis has been observed to squeak shortly before +the emergence of the perfect form. + +The fore wings of this moth are of a very rich dark brown, beautifully +mottled with lighter tawny shades, and with a small but conspicuous +yellow dot near the centre. The hind wings are yellow, with a black band +and margin; and the body is yellow, with six broad black bands, and six +large blue spots down the middle. + +[Illustration: FIG. 97.--THE DEATH'S-HEAD HAWK MOTH.] + +The moth is rather widely distributed, and even common in some parts, +but is not nearly so often met with as the larva. It is on the wing +during August and September. + +It is probable that the reader will never have an opportunity of +capturing the perfect form of this remarkable species, but he may with a +little perseverance obtain some caterpillars and rear them. These larvae +feed on the potato, the deadly nightshade (_Atropa Belladonna_), and the +woody nightshade (_Solanum Dulcamara_); and they are well known to +potato growers in some parts of the country. + +The colour of the caterpillar is generally pale yellow, with numerous +small black dots, and seven oblique violet stripes on each side. The +horn is yellowish and rough, and is bent downward, but recurved again at +the tip. + +It feeds during the night, and remains hidden throughout the daytime. In +August it is fully grown, and then retires into the ground to undergo +its transformations. + +[Illustration: FIG. 98.--THE LARVA OF ATROPOS.] + + +_The Privet Hawk_ (_Sphinx Ligustri_) + +This is another fine moth, measuring nearly four and a half inches from +tip to tip. It is represented in the centre of Plate IX in its natural +colours, so that it need not be described. + +The perfect insect flies in June and July, and, although common, is not +frequently seen at large. The larvae, however, are to be met with in +abundance in privet hedges. Even in the centres of large towns we may +see them resting on the topmost twigs of a privet hedge, their beautiful +green tint closely resembling that of the surrounding leaves. After a +little experience they may be readily discerned by a careful observer, +but there are certain signs by which their presence may be proved before +they have been actually seen. Sometimes a number of the twigs are +completely stripped of their leaves, even the midribs and the leaf +stalks being almost or entirely devoured; and beneath the bushes are +the large black masses of excrement that tell of the marauders above. +When found, these larvae should always be removed on a piece of the twig +to which they are attached, for they hold on so firmly by their claspers +that it is sometimes almost impossible to remove them from their hold +without injury. + +These caterpillars may easily be distinguished from those of the other +'hawks' by the seven oblique stripes which adorn the sides. These are +each composed of two colours, white and lilac, and form a pretty +contrast with the bright green of the rest of the body. The horn is +smooth and curved, and is black with the exception of part of the under +side, which is yellow. + +They are fully grown in August, and from the end of this month till the +following June the chrysalides may be dug out from under privet and +lilac bushes, both of which are attacked by the larva. + + +_The Spurge Hawk_ (_Deilephila Euphorbiae_) + +This is a very rare British species; in fact, it has never been seen in +this country in its perfect state, but the larva has been found +plentifully at Appledore and Braunton Burrows, in North Devon, feeding +on the sea spurge (_Euphorbia Paralias_). + +The perfect insect is shown on Plate IX (fig. 2). + +[Illustration: FIG. 99.--THE CATERPILLAR OF EUPHORBIAE.] + +The caterpillar is black, with a large number of small yellowish white +dots, and two rows of spots of the same colour on each side. There is +also a red line on each side, and another down the middle of the back. +The horn is rough and red with a black tip. It feeds during August and +September. + + +_The Small Elephant Hawk_ (_Chaerocampa Porcellus_) + +This pretty insect is one of the smallest of our hawk moths. It is +widely distributed, being met with in many parts of England and in the +south of Scotland. It flies in June. + +The fore wings are of a dull yellow colour, with rosy-red hind margins, +and a broad border of the same tint on the costal margin. The hind wings +have also a rosy-red hind margin, and are smoky black along the costae, +and yellow in the anal angle. The body is coloured with bright rose-red, +tinged with olive on the foremost and hindmost segments. + +The popular name of this and the following species has been applied +because of the power which the caterpillar has of extending and +retracting its front segments, a peculiarity which has given the idea of +a semblance to the elephant's proboscis. The colour of the caterpillar +is light-brown or green, mottled with dark-brown, dark-green, or black. +It has a conspicuous eye-like spot on each side of the fifth and sixth +segments, and has no horn. + +[Illustration: FIG. 100.--THE SMALL ELEPHANT HAWK MOTH.] + +This larva may be found in July and August, feeding on species of +bedstraw (_Galium verum_, _G. Mollugo_, and _G. palustre_), willow herb +(_Epilobium hirsutum_), or the purple loosestrife (_Lythrum Salicaria_). + + +_The Large Elephant_ (_Chaerocampa Elpenor_) + +This species (Plate IX, fig. 3) is very similar to the last in form and +markings; but is, as its name implies, larger. + +The caterpillar, too, is very like that of the last species, but may be +distinguished from it by the possession of a short black horn, tipped +with white, on the 'tail.' Its colour is green or brown, mottled and +spotted with black. The eye-like spots on its fifth and sixth segments +are black, and each contains a brown spot surrounded by a white line. + +Its chief food plants are the hairy willow herb (_Epilobium hirsutum_), +three species of bedstraw (_Galium verum_, _G. Mollugo_ and _G. +palustre_), the purple loosestrife (_Lythrum Salicaria_), and the +enchanter's nightshade (_Circaea lutetiana_). It will also feed on the +vine and the apple in confinement. + + +_The Eyed Hawk_ (_Smerinthus Ocellatus_) + +Our next genus (_Smerinthus_) contains three well-known moths, all of +which have the hind margin of the fore wings angulated or indented. + +The first is the Eyed Hawk, represented in fig. 4 of Plate IX and named +after the beautiful and conspicuous eye-like spot near the anal angle of +each hind wing. + +The caterpillar has a rough green skin, sprinkled with white dots, and +marked with seven oblique white lines on each side, each of which is +bordered with dark green above. The spiracles are pinkish, surrounded by +violet rings; and the horn is blue. + +The moth flies during May, June, and July; and the caterpillar may be +found in plenty during August, feeding on the apple, willow (_Salix +alba_), sallow (_S. cinerea_ and _S. Caprea_), poplar (_Populus alba_ +and _P. nigra_), aspen (_P. tremula_), and the blackthorn (_Prunus +spinosa_). + +As with many other _Sphinges_, the larvae are much more commonly seen +than the perfect insects; but the latter may often be met with resting +on tree trunks and fences in the neighbourhood of their food plants. + + +_The Poplar Hawk_ (_Smerinthus Populi_) + +[Illustration: FIG. 101.--THE POPLAR HAWK.] + +This moth is very common and very widely distributed, and may be easily +found in any of its stages. The perfect insect flies during May, June, +and July; and being rather heavy on the wing, it is easily taken with a +net as it hovers round the branches of its favourite trees or among the +flowers of gardens at dusk. The larva may be beaten from the boughs of +poplars and sallows during August and September, and during the latter +month may often be seen creeping down and around the trunks of these +trees, searching for a suitable spot in which to undergo its changes. +The pupa may be dug out of the soil at the foot of the same trees +during the autumn, winter, and spring months. + +The fore wings are ashy grey or greyish brown, marbled with darker +tints, with a conspicuous white spot near the centre. The hind wings are +similarly coloured except at the base, where there is a large patch of +brick-red. + +The caterpillar is rough, of a pale green colour dotted with yellow, +with seven oblique yellow stripes on each side. The spiracles are white, +edged with red; and the horn is yellow on the upper, and reddish on the +under side. Its chief food plants are the poplar, the Lombardy poplar +(_Populus pyramidalis_), aspen (P_. tremula_), and sallow (_Salix +Caprea_ and _S. cinerea_). + + +_The Lime Hawk_ (_Smerinthus Tiliae_) + +This beautiful moth (fig. 5, Plate IX) is easily identified by its rich +olive green and brown wings, the fore pair of which have very +conspicuous patches of deep olive, sometimes uniting to form a +continuous central bar. It flies in May and June. + +The caterpillar is rough, of a pale green colour, dotted with yellow, +with seven oblique yellow stripes on each side. Thus it is very like the +larva of _Populi_, but may be distinguished from that species by the +orange spiracles, and by the horn, which is rough, blue above, and +yellow beneath. Behind the horn, too, there is a flat purple or violet +scale with an edging of orange. + +The food plants of this species are the lime (_Tilia vulgaris_), elm +(_Ulmus campestris_), and the hazel (_Corylus Avellana_), from which the +larvae may be beaten in August and September, and from under these the +pupae may be dug out during the winter months. + + +_The Humming-Bird Hawk_ (_Macroglossa Stellatarum_) + +The genus to which this insect belongs contains three interesting +British species. Their antennae are thickened toward the end, but +terminate in a small curved bristle. Their wings are rather short and +broad; their bodies are very thick, terminating in a broad tuft of hair; +and the perfect insects fly during the daytime, delighting in the +hottest sunshine. The larvae feed principally on low-growing plants, and +undergo their metamorphoses on the ground among the foliage. + +On Plate IX (fig. 6) one of these pretty moths is shown. It is the +Humming-bird Hawk, so called on account of its exceedingly rapid +humming-bird-like flight, accompanied by a soft humming sound. + +This insect is very common; and, being very partial to the attractions +offered by many of our favourite garden flowers, it ought to be well +known to all observers of nature. + +Take your stand near a bed of petunias or verbenas, or close to a +honeysuckle in bloom, on any hot summer's day, and you are almost sure +to be rewarded by a peep at the wonderful flight and interesting ways of +this moth. It makes its appearance so suddenly that you first view it as +an apparently motionless insect, suspended in the air, and thrusting its +long proboscis into the tube of an attractive flower. Its wings vibrate +so rapidly that they are quite invisible, and give rise to the soft hum +already mentioned. Then it darts from one flower to another, making a +similar brief stay before each while it sucks the grateful sweets. Raise +your hand as if to strike, and suddenly it vanishes you know not where. +But it is as bold as it is wary, and will often return to the selfsame +flower as if to defy your power. A sharp sweep of your net in a +horizontal direction, or a sudden downward stroke, _may_ secure it; but +if you miss it, as you probably will, it will disappear like a phantom, +and give you no opportunity of making a second attempt. + +This moth is on the wing throughout the hottest months of the year--May +to September, and will often greet you as you roam over flowery banks in +search of butterflies. + +The caterpillar feeds on the lady's bedstraw (_Galium verum_), hedge +bedstraw (_G. Mollugo_), and the goose grass (_G. Aparine_), and may be +searched for in August and September. It is rough, green or brownish, +and dotted with white. Along each side are two light lines. The horn is +thin and short, rough, and points upwards. + + +_The Broad-bordered Bee Hawk_ (_Macroglossa Fuciformis_) + +The two other moths of this genus are called Bee Hawks from their +resemblance to the humble bee. They are very much alike, but may be +distinguished by a difference in the width of the dark border of the +wings; and are named Broad-bordered and Narrow-bordered respectively. + +The former is illustrated in the woodcut appended. The fore wings are +transparent like those of bees, with a dark central spot and a broad +reddish-brown hind margin. The base and costa are black and tinged with +green. The hind wings are similarly coloured, but have no central spot. +The body is olive-brown, with a broad reddish belt, and behind are tufts +of hair, which are spread out when the insect flies, just after the +manner of the tail feathers of a bird. The moth flies in May. + +[Illustration: FIG. 102.--THE BROAD-BORDERED BEE HAWK.] + +The larva resembles that of _Stellatarum_, but exhibits a violet tint +above the legs. Its horn, too, is curved, and of a reddish or brownish +colour. It feeds on the honeysuckle (_Lonicera Periclymenum_), ragged +robin (_Lychnis Flos-cuculi_), evening campion (_L. vespertina_), red +campion (_L. diurna_), lady's bedstraw (_Galium verum_), and the field +scabious (_Scabiosa arvensis_), during the month of July. + + +Family SESIIDAE--THE CLEARWINGS + +This family contains fourteen very pretty British insects that differ +very much from other moths in many important and interesting +particulars. + +Their antennae, like those of the _Sphingidae_, are thickest beyond the +middle, and those of the males are slightly _ciliated_ or hairy. Their +bodies are slender, and terminate behind in tufts of hair. The hind +wings in all cases are transparent, margined and veined with black or +brown; and the fore wings also, in most cases, have transparent bases. + +These moths delight in the hottest sunshine, and may be seen gracefully +hovering over the flowers in our gardens, looking more like gnats, bees, +and wasps, than moths. + +The larvae of these insects are all wood-eaters, and spend their time +within the stems of shrubs and trees, eating out galleries in the +material that forms both their food and their home. Within these they +also undergo their changes, and do not expose themselves to the free air +and light till they reach their perfect stage. + + +_The Hornet Clearwing of the Poplar_ (_Trochilium Apiformis_) + +We can find space for a mention of only two of the clearwings, the first +of which is an insect that closely resembles the dreaded hornet, and +whose larva feeds in the stems of poplars--features which will account +for the above name. + +[Illustration: FIG. 103.--THE HORNET CLEARWING OF THE POPLAR.] + +The head of this species is yellow, its thorax brown with a large yellow +patch on each side, its abdomen yellow with two brown belts, and its +legs reddish orange. The front wings are transparent, with brown costae, +and all the wings are margined with brown. + +The caterpillar, when full fed, makes a cocoon with silk and the chips +of wood that it has bitten off; and in this undergoes its metamorphoses. +It is fully grown in April, and the moth flies from the end of May to +the end of July. + +There is another 'Hornet Clearwing,' the larva of which feeds on the +stems of osiers. It may be distinguished from the species just described +by a yellow 'collar' between the head and thorax, both of which are +blackish. + + +_The Currant Clearwing_ (_Sesia Tipuliformis_) + +This is by far the commonest of all the Clearwings, and only too well +known to those who grow currants. Examine the shoots of _Ribes rubrum_ +(red currant) and _R. nigrum_ (black currant), especially those that +present a withered or half-withered appearance, and you will almost +certainly meet with signs of the presence of this intruder. Little +wriggling larvae occupy the pithless stems throughout the winter and +spring. These are full grown in April, and in June the pretty little +moth emerges through a hole in the side of a shoot, leaving the empty +pupa case within its former home. + +[Illustration: FIG. 104.--THE CURRANT CLEARWING.] + +The fore wings of this moth have black margins, and a black transverse +bar beyond the middle. The body is black, with three pale yellow belts, +and black tufts of hair at the tip. + + +Family--ZYGAENIDAE + +The remaining family of the _Sphinges_--the _Zygaenidae_--includes seven +British species, three of which are known popularly as the Foresters and +the others as the Burnets. + +Their antennae are thickest beyond the middle, but do not terminate in a +hook. Their wings are narrow and completely covered with scales. + +These moths are very sluggish creatures, spending the greater part of +their time at rest on the stems of low-growing plants. When they do fly, +their flight is short and heavy, and their pretty wings glisten in the +sunshine (for they are lovers of the sun), giving them the appearance of +bees rather than of moths. On account of this natural sluggishness, they +are exceedingly local, for they never move far from the spots where +their food plants abound, and where they had previously spent the +earlier stages of their existence. Thus we often come across a very +limited piece of ground actually alive with them, and outside which not +a single specimen is to be seen. + +The larvae, too, are sluggish creatures, with soft and plump cylindrical +bodies and no horns. I will briefly describe three members of this +family. + + +_The Forester_ (_Ino Statices_) + +The fore wings of this species are semi-transparent, and of a beautiful +glossy green. The hind wings also are semi-transparent, but of a dull +smoky tint. The thorax and abdomen are both of a brilliant metallic +green colour. The tips of the antennae are blunt, and the male may be +distinguished from his mate by these organs being slightly fringed or +ciliated. + +[Illustration: FIG. 105.--THE FORESTER.] + +The caterpillar is dingy grey or greenish, with a row of black spots +down the back, and a whitish stripe on each side. It feeds on the common +sorrel (_Rumex acetosa_) and the sheep sorrel (_R. acetosella_), and +when fully grown it spins a cocoon on the stem of its food plant, and +there changes to a chrysalis. + +The larva may be found during May and early June. The chrysalis state +lasts only a few days, and the moth is on the wing during June and +July. + + +_The Broad-bordered Five-spotted Burnet_ (_Zygaena Trifolii_) + +On Plate IX (fig. 7) will be found a coloured representation of this +Burnet. The two crimson spots in the base of the fore wing are very +close together, and often touch. The same remark also applies to the two +spots on the middle of the wing. A glance at the list of British Moths +(Appendix I) will show that we have also a _Narrow_-bordered +Five-spotted Burnet. This insect is very similar to the species now +under consideration, but may be identified by the narrower purplish +margin on the hind wings, and also by the shape of the antennae, which +are not thickened so much near the end as they are in _Trifolii_. + +The larva of the present species is yellowish or greenish, with a row of +black spots on the back and a row on each side. It feeds on the +bird's-foot trefoil (_Lotus corniculatus_), hop trefoil (_Trifolium +procumbens_), and the horse-shoe vetch (_Hippocrepis comosa_) in May. +Late in May or in early June the chrysalis may be found in a silken +cocoon attached to a stem or leaf; and the perfect insect flies during +June and July. + + +_The Six-spotted Burnet_ (_Zygaena Filipendulae_) + +So common is this moth, and so conspicuous when it flies in the blazing +sun, that it must be familiar to almost everybody. On a bright midsummer +day hundreds may often be started from their grassy beds from one little +patch of ground. + +[Illustration: FIG. 106.--THE SIX-SPOTTED BURNET.] + +[Illustration: FIG. 107.--THE LARVA OF FILIPENDULAE.] + +The colouring of the wings is much the same as in the last species, but +there are two crimson spots instead of one near the tips of the fore +pair. + +The larvae may be seen in vast numbers during May and June, feeding on +clovers (_Trifolium pratense_ and _T. repens_), and the bird's-foot +trefoil (_Lotus corniculatus_); and in the latter month thousands of the +chrysalides, inclosed in shuttle-shaped cocoons on grass stems, may be +seen on downs and sunny banks in almost every part of the country. + +The caterpillar, which is yellow, may be known by the two rows of black +spots that adorn each segment of the body. + + + + +CHAPTER XVIII + +_BOMBYCES_ + + +This tribe is an important one, inasmuch as it contains those few moths +whose silk is of present or anticipated commercial value. Many of the +British members, even, make silken cocoons of moderate compactness, but +none of them yield a quantity and quality of silk to justify any attempt +to utilise it in the arts. + +There are more than a hundred British species in this group, and these +represent no less than seventeen families, which exhibit a great variety +in their general appearance and habits. + + +Family--NYCTEOLIDAE + +_The Green Silver-lined_ (_Hylophila prasinana_) + +This family, under the name of _Chloephoridae_, is included by some +authors among the _Tortrices_ (page 298), which they somewhat resemble +in habits. It contains only four species, of which we will take one +example--the Green Silver-lined. + +[Illustration: FIG. 108.--THE GREEN SILVER-LINED.] + +The fore wings of this insect are pale green, with three oblique silvery +white lines, the middle one of which is far more distinct than the other +two. The hind wings are silvery white in the female, and yellow in the +male. It flies in May, and is common in the wooded districts of the +south-eastern counties. + +The caterpillar is pale green, dotted and striped with yellow, and has a +reddish transverse band on the second segment. It feeds on oak (_Quercus +Robur_), birch (_Betula alba_), hazel (_Corylus_ _Avellana_), beech +(_Fagus sylvatica_), and alder (_Alnus glutinosa_), from which trees it +may be beaten in July and August. + + +Family--NOLIDAE + +_The Short-cloaked Moth_ (_Nola cucullatella_) + +We select this common moth as a representative of the small family +_Nolidae_, which contains only five British species. These are all small +insects. They are nocturnal in their habits, and may be found at rest on +the trunks of trees during the daytime. The caterpillars are hairy, and +undergo their metamorphoses within silken cocoons. + +[Illustration: FIG. 109.--THE SHORT-CLOAKED MOTH.] + +The fore wings of _Cucullatella_ are pearly grey, with a dark patch at +the base, a triangular spot on the middle of the costal margin, and wavy +lines beyond this, parallel with the hind margin. The hind wings are +grey, and devoid of any markings. + +The caterpillar is of a brownish colour, with a line of lighter patches +down the back, and it is covered with little tufts of hair. It feeds on +the blackthorn (_Prunus spinosa_), whitethorn (_Crataegus oxyacantha_), +and also on plum trees in our gardens during the month of May. The moth +is on the wing during June and July. + + +Family--LITHOSIIDAE + +_The Muslin Moth_ (_Nudaria mundana_) + +The family _Lithosiidae_ contains several small moths, distinguished from +the other _Bombyces_ by the narrowness of their fore wings. When the +insects are at rest, all the wings are wrapped closely round the body. +They fly at dusk on summer evenings, but may be obtained during the +daytime by beating the boughs of trees. If an open net be held under the +boughs during this operation, the moths will generally feign death and +allow themselves to fall into it when they are disturbed. + +[Illustration: FIG. 110.--THE MUSLIN MOTH.] + +Most of the larvae of this family feed on the lichens that cover walls +and the bark of trees, and they conceal themselves so artfully among +this peculiar vegetation that it is no easy matter to search them out; +probably many still remain unknown to entomologists. + +Our first example--the Muslin Moth--has light brownish-grey and semi +transparent wings, the front pair of which have darker markings arranged +as shown in the illustration. It is a common moth, and may be met with +in July and August. + +The caterpillar feeds on lichens in June. It is of a dull grey colour, +with a yellow stripe down the back, and has numerous little tufts of +light hair. + + +_The Common Footman_ (_Lithosia lurideola_) + +The fore wings of this species are of a leaden grey, with a bright +yellow costal stripe which dwindles to a point just before it reaches +the tip. The hind wings are very pale yellow. + +[Illustration: FIG. 111.--THE COMMON FOOTMAN.] + +The larva is black, with a reddish line on each side just above the +feet. It may be found during May and June among the lichens of oaks, +blackthorns, and firs, especially in the woods of the south of England. + +The perfect insect flies during July and August. + + +Family--EUCHELIIDAE + +_The Cinnabar_ (_Euchelia Jacobaeae_) + +The family _Eucheliidae_ contains only four British species, two of which +must receive a share of our attention. The first of these is the +Cinnabar Moth, which is common in all localities where its food +plants--the groundsel (_Senecio vulgaris_) and the ragwort (_S. +Jacobaea_)--abound. + +[Illustration: FIG. 112.--THE LARVA OF JACOBAEAE.] + +Its colours are so striking that a glance at its representation (fig. 1 +of Plate X) will render a written description quite unnecessary. + +The caterpillar is a very familiar and conspicuous object. Its colour is +bright orange, broken by several broad black rings; and its body is +thinly covered with hair. When fully grown (July or August) it descends +to the ground, and there changes to a smooth and shining reddish-brown +chrysalis. + +The moth appears in June or early in July. + + +_The Scarlet Tiger_ (_Callimorpha Dominula_) + +This is certainly one of the most beautiful of all our moths. Its fore +wings are dark olive green, with a lovely metallic lustre, and boldly +marked with large white and yellow spots. These spots are arranged +generally like those in the illustration, but are subject to great +variation. The hind wings are crimson, with large black patches, chiefly +distributed near the hind margin. The thorax is black, with two white +streaks; and the abdomen crimson, with a black line down the back. + +[Illustration: FIG. 113.--THE SCARLET TIGER.] + +This moth is a common one. It may be taken in June and July. I have seen +it flying somewhat freely while the sun was still shining brightly. + +The caterpillar is very dark lead colour, nearly black; and is covered +with little wart-like projections, from each of which protrudes a short +black hair. There is a broad yellow broken line down the back, and two +others on the sides. It feeds on the hound's-tongue (_Cynoglossum +officinale_) and many other low-growing plants, hybernates through the +winter, and is fully grown in May. Like the other members of this +family, it spins a light silken cocoon, in which the hairs from its body +are interwoven. + + +Family--CHELONIIDAE + +_The Wood Tiger_ (_Nemeophila Plantaginis_) + +The _Cheloniidae_ are popularly known as the Tigers--a title suggested by +the tiger-like colouring of some of the prominent species. They differ +from the Scarlet Tiger and the other members of the _Eucheliidae_ in that +the males have ciliated or fringed antennae. The larvae, too, are more +densely covered with hair. + +The Wood Tiger (fig. 2, Plate X) is a beautiful insect, somewhat +variable in its markings, but so conspicuously coloured that our +illustration cannot fail to lead to its identification. It may be found +commonly among the undergrowth of our southern woods during May and +June. + +The caterpillar is dark brown or brownish black, covered with little +hair-bearing warts. The hairs are long and black on the foremost and +hind segments, but shorter and of a brown colour on the middle of the +body. It issues from the egg in September, feeds for a week or two on +the leaves of violets (_Viola canina_ and _V. odorata_), heartsease (_V. +tricolor_), plantain (_Plantago_), or groundsel (_Senecio vulgaris_), +and then hybernates till the following March. It is fully grown in May, +and then spins a light cocoon, with which its hairs are interwoven, +among the leaves of its food plant. + + +_The Tiger_ (_Arctia caia_) + +This splendid moth is exceedingly variable in its colour and markings, +but its usual appearance corresponds closely with that of the +illustration on Plate X (fig. 3). In some specimens the cream colour +almost entirely covers the fore wings, while in others all four of the +wings are completely covered with shades of brown. This insect is +probably known to all my readers, for it is abundant everywhere. + +The larva is as well known as the perfect insect. It is a kind of +universal feeder, partaking readily of almost every low-growing plant, +with perhaps a special partiality for dead nettles (_Lamium album_ and +_L. purpureum_). It feeds also on the lime tree (_Tilia vulgaris_), and +is commonly met with on apple trees and on the various plants of our +flower beds. The young caterpillar makes its appearance in the autumn, +and hybernates after feeding for two or three weeks only. It is full +grown in June, when it spins a silken cocoon, and changes to a shiny +black chrysalis. + +The ground colour of the larva is black, but it is covered all over with +long hairs, those down the middle of the back being grey, and the others +brown. This familiar larva is known popularly as the Woolly Bear. + + +_The Cream-spot Tiger_ (_Arctia villica_) + +There is yet another Tiger--the Cream-spot--too beautiful and too common +to be excluded from our list. It is represented on Plate X (fig. 4); +and, like the others of its genus, is so boldly marked that mistaken +identity is impossible. + +It is a very sluggish moth, more often seen at rest than on the wing, +and will suffer itself to be roughly handled without making any attempt +to escape. + +The caterpillar may be observed on sunny banks, generally feeding on +chickweed (_Stellaria media_) but sometimes on various other low-growing +weeds, including the dock and the dandelion. Its colour is black, with +red head and legs, and its body is covered with long brown hairs. It +commences to feed in the autumn, hybernates throughout the winter, and +is full grown in May, towards the end of which month it changes to a +black chrysalis within a light silken web. + +The perfect insect appears in June. + + +_The Buff Ermine_ (_Spilosoma lubricipeda_) + +The _Cheloniidae_ also include three moths that are popularly known as +the Ermines, two of which--the Buff and the White--are exceedingly +common, and are among the constant visitors to our gardens during June +and July. + +[Illustration: FIG. 114.--THE BUFF ERMINE.] + +The Buff Ermine has all four wings of a buff or ochreous tint, and +spotted with black as here represented. + +The caterpillar is whitish, with a white line down the middle of the +back, and its body is covered with long light brown hairs. It feeds on +the dock (_Rumex_) and many other low-growing plants during August and +September, and spends the winter in the chrysalis state, lying within a +loose cocoon on the surface of the ground. + +[Illustration: FIG. 115.--THE WHITE ERMINE.] + + +_The White Ermine_ (_Spilosoma Menthastri_) + +In this species the wings are of a pale cream colour, and the dots of +the fore wings are more uniformly distributed than in the last. Its +habits and life history closely correspond with those of _Lubricipeda_, +and its larva may be found feeding on the same plants. + +This latter may be distinguished from the caterpillar of the last +species by the dark brown or black colour of the body, and the presence +of an orange line down the back. It is covered with long brown hairs. + + +Family--HEPIALIDAE + +The five species which compose this family are known as the Swifts, a +title which they have earned by their rather rapid flight. Their wings +are narrow, and the antennae very short. + +In the larval state they are long, naked and unsightly grubs, that live +under the surface of the ground and feed on the roots of plants. The +chrysalides are armed with short spines projecting from the segments. + + +_The Ghost Swift_ (_Hepialus Humuli_) + +One of the commonest of these moths is the Ghost Swift, which may be +seen in hundreds on waste places in the south of England during the +month of June. The wings of the male are white, with a silky gloss, and +a very narrow brown margin. The fore wings of the female are yellow, +marked with irregular reddish lines. The hind wings are of a dull smoke +colour. + +[Illustration: FIG. 116.--THE GHOST SWIFT--FEMALE.] + +The larva is pale yellow, with a brown head, and a brown horny plate on +the front of the second segment. It feeds throughout the winter on the +roots of numerous plants, including the dock, dandelion, burdock, white +dead nettle, black horehound, and the hop. + + +_The Common Swift_ (_Hepialus lupulinus_) + +The fore wings of the male of this species are brown, with a bent +whitish streak, sometimes broken, passing from the base to the middle of +the inner margin, and then to the apex. The hind wings are smoke +coloured, with a light brownish fringe. The female is much less +distinctly marked, and presents a rather dingy appearance. + +[Illustration: FIG. 117.--THE COMMON SWIFT.] + +The larva is dingy white, with brown horny plates on the second, third +and fourth segments. It feeds on the roots of dead nettles (_Lamium +album_ and _L. purpureum_), black horehound (_Ballota nigra_), and +various other herbaceous plants, throughout the winter months, and is +full grown in April. + +This insect is abundant everywhere in waste places, and may be seen on +the wing in May and June. + + +Family--COSSIDAE + +The members of this family have longer antennae than the _Hepialidae_, and +the females are provided with extended ovipositors which enable them to +place their eggs in the deep crevices of the bark of trees. + +The larvae are naked or only very slightly hairy, and have a plate on the +second segment. They feed on the wood of trees or the interior of the +stems of reeds. The pupae have spiny projections on each segment. + + +_The Goat Moth_ (_Cossus ligniperda_) + +There are only three British species of this family, the largest of +which is the Goat Moth, so called on account of the characteristic odour +of the larva, an odour said to resemble that emitted by the goat. + +The fore wings of this fine moth are pale brown, clouded with white, and +marked by numerous wavy transverse lines. The hind wings are somewhat +similar, but of a duller tint, and the markings are less distinct. Its +average breadth from tip to tip is over three inches, and it sometimes +reaches nearly four inches. + +The larva is a most interesting creature. It is dark reddish brown on +the back, and flesh colour beneath; and its head is intensely black. It +feeds on the solid wood of the willow, poplar, oak, elm, and other +trees. The infected trees are often so riddled with the burrows of these +larvae that they are completely destroyed, and the presence of the +intruders is frequently indicated by a heap of small chips of wood lying +on the ground near the roots. The odour of the larvae, too, is so +powerful, that there is generally no difficulty in ascertaining their +whereabouts by it alone. + +[Illustration: FIG. 118.--THE GOAT MOTH.] + +It is not always in living trees, however, that we find these creatures, +for they often feed on rotting wood, such as the remains of old palings +and posts, that lie on the ground in damp places. + +[Illustration: Fig. 119.--THE LARVA OF LIGNIPERDA (LESS THAN HALF FULL +SIZE).] + +When fully grown they construct a strong cocoon of chips of wood, bound +together by silk, and within this they change to the chrysalis. + +The moth emerges in June or July, and is commonly found resting on the +bark of willows and poplars during the daytime. + + +_The Leopard Moth_ (_Zeuzera pyrina_) + +The wings of this species are white and semi-transparent, and marked +with numerous bluish-black spots in such a way as to remind one of the +skin of the leopard. Its body is very long, and the antennae of the male +are doubly fringed for about half their length from the base. + +[Illustration: FIG. 120.--THE LEOPARD MOTH.] + +The caterpillar feeds on the wood of various trees--elm, apple, pear, +ash, alder, poplar, horse chestnut, birch, lilac, and several others. It +is yellowish, with black shiny spots, and a black plate on the second +segment. + +[Illustration: FIG. 121.--THE LARVA OF PYRINA (ONLY PARTLY GROWN).] + +The moth appears in July, and is widely distributed. It is attracted by +bright lights, but the best way to obtain it is to search the trunks and +branches of trees that are known to harbour the larvae early in the +morning, and so obtain newly emerged specimens. + + +Family--LIPARIDAE + +Passing over the two small species which are the only British +representatives of the family _Cochliopodidae_, we come to the +interesting _Liparidae_, the remarkable feature of which is that most of +the caterpillars are adorned with brush-like tufts of hair, and even the +chrysalides are hairy. + +The perfect insects are not brilliantly coloured, but generally display +very pale tints; and the antennae of the males are pectinated or +feathered. + + +_The Brown Tail_ (_Porthesia chrysorrh[oe]a_) + +The family contains two moths--the Brown Tail and the Yellow Tail--that +are very similar in appearance and habits. Both have white wings, and +their bodies also are white with the exception of the tuft of coloured +hair at the tip of the abdomen, which gives the names to the species. +Their larvae may both be found feeding on the same trees (whitethorn), +and both change to a brown hairy chrysalis within a loose cocoon among +the leaves. + +The larva of _Chrysorrh[oe]a_ is black, with four rows of little +wart-like projections on each side, from which proceed little tufts of +hairs. These hairs are reddish with the exception of one row on each +side, which is white. The tenth and eleventh segments have each a +scarlet tubercle, and there are also other small spots of the same +colour on some of the front segments. + +[Illustration: FIG. 122.--THE BROWN TAIL.] + +The larva feeds on the blackthorn in addition to the tree mentioned +above, and is full grown in June. The moth flies in August. + + +_The Gipsy_ (_Ocneria dispar_) + +The fore wings of the male are smoky brown, with darker markings, +including a V-shaped black mark near the centre. The hind wings are +brown, darker near the margin. The female is dingy yellowish white, with +darker markings arranged as in the male. The male is much inferior in +size, and its antennae are very strongly pectinated. + +[Illustration: FIG. 123.--THE GIPSY--MALE.] + +The larva is brownish black, finely dotted with yellowish grey. There is +a grey stripe down the middle of the back, and six tubercles on each +segment give rise to tufts of long hair. It feeds on the whitethorn +(_Crataegus oxyacantha_), blackthorn (_Prunus spinosa_), and various +fruit trees. + +The caterpillar is full grown in June, and the moth appears in August. + + +_The Black Arches_ (_Psilura Monacha_) + +The fore wings of the Black Arches are white, marked with zigzag black +lines as shown in our illustration. The hind wings are smoky grey. The +hinder segments of the abdomen are banded with black and rose-pink. The +male is much smaller than the female, and has the antennae strongly +pectinated. + +[Illustration: FIG. 124.--THE BLACK ARCHES--MALE.] + +The caterpillar is hairy, and of a greyish-white colour. A brown stripe +runs down the back. On the top of the second segment are two blue +tubercles; and there is also a tubercle, of a reddish colour, on each of +the ninth, tenth, and eleventh segments. It feeds on the oak, birch, +fir, and the apple; and is full grown in June or July. + +The moth flies during July and August. + + +_The Vapourer Moth_ (_Orgyia antiqua_) + +During the hottest summer months, and particularly in August and +September, a rather small brown moth may be seen almost everywhere, +flying rapidly and in a very erratic manner in the bright rays of the +midday sun. This is the common Vapourer Moth, which may be known at once +by its bright chestnut colour, with darker transverse markings, and a +white crescent-shaped spot in the anal angle of the fore wings. It seems +somewhat partial to civilised life, for it frequents the streets of our +metropolis, even in the very densely populated parts; and the larva is +one of the commonest of the insect forms infesting our gardens and +squares. + +[Illustration: FIG. 125.--THE VAPOURER MOTH--MALE.] + +[Illustration: FIG. 126.--THE FEMALE VAPOURER.] + +The caterpillar is variously coloured; but the prevailing tints are dark +brown, grey, and pink. On the second segment are two long tufts of hair +directed forward, and on the twelfth segment a similar tuft directed +backward. On each of the segments five to eight inclusive is a +brush-like tuft of yellowish hairs. It feeds on almost every tree +usually to be found in parks and gardens. + +When fully grown it spins a web on the bark of a tree, or on a wall or +fence, and changes to a hairy chrysalis. + +[Illustration: FIG. 127.--LARVA OF THE VAPOURER MOTH.] + +The female of this species is wingless, and never moves away from the +cocoon out of which she has crawled, but lays her eggs on the outside of +the silken web, and there remains to die. + +The clusters of eggs may be found in abundance throughout the winter +months. + + +Family--BOMBYCIDAE + +This family contains eleven thick-bodied moths, mostly of large size, in +which the predominating colours are greys and browns. Their hind wings +are generally paler than the front pair, and less distinctly marked; and +the antennae of the males are pectinated. + +The caterpillars are very hairy, but the hairs are uniformly +distributed, and not arranged in tufts as in the larvae of the last +family. + +The chrysalides are inclosed in silken cocoons, but are not hairy. + +We shall briefly examine three of the members of this family. + + +_The Oak Eggar_ (_Bombyx Quercus_) + +The male of this species is shown on Plate X (fig. 5). The female is +much larger, and of a pale tawny colour. + +The ground colour of the caterpillar is black; but it is so closely +covered with short yellowish brown hairs that the black is scarcely +visible, excepting when the creature rolls itself up into a ring, which +it does when alarmed. The spiracles are white, and there is a series of +white spots down the middle of the back and along each side. It feeds on +whitethorn (_Crataegus oxyacantha_), heather (_Calluna_, _Erica_), poplar +(_Populus nigra_), and various other plants and trees. + +As a rule the larva hybernates through the winter, is full grown in the +following May, and the moth appears in July; but in Scotland the +caterpillar does not spin its cocoon till September, hybernates in the +chrysalis state, and emerges in the following June. The same is true of +the Cornish Eggars; but along the coast of South Devon both varieties +are to be met with. + +The male Eggar seems to enjoy the bright sunshine, for I have seen large +numbers flying over the rugged cliffs of the south-west throughout all +hours of the day. + + +_The Drinker_ (_Odonestis potatoria_) + +The popular name of this species is applied on account of a peculiar +feature of the larva, which sucks up the dewdrop that lies on its food +plant. + +The colour of the male is tawny and brown, with a reddish tinge; that of +the female is yellow. The front wing has an oblique dark bar passing +from the apex to the middle of the inner margin; also two white +spots--one in the middle of the wing, and the other between it and the +costal margin. + +[Illustration: FIG. 128.--THE DRINKER--MALE.] + +The caterpillar is dark bluish grey above, and has a line of orange +spots on each side. Along the spiracles are oblique orange streaks, and +a series of tufts of white hair. It feeds on the annual meadow-grass +(_Poa annua_), and several other grasses. It is a hybernator, commencing +its caterpillar state in the autumn, and reaching its full dimensions +about the end of the following May. + +The moth flies during July and August. + + +_The Lappet_ (_Lasiocampa quercifolia_) + +Our last example of the _Bombycidae_ is the Lappet (Plate X, fig. 6), a +large moth, the female often measuring considerably over three inches +from tip to tip. The wings are of a rich reddish brown, and exhibit a +beautiful purplish bloom in a newly emerged insect. Scalloped black +lines pass transversely across each wing, and a small black dot lies +near the centre of the fore wings. + +The caterpillar is very variable in colour, but is usually grey or +reddish brown. A deep purple band lies between the second and third +segments, and another between the third and fourth. On the twelfth there +is a small hump, and a pale stripe, more or less distinct, runs along +each side. It feeds on the blackthorn (_Prunus spinosa_), buckthorn +(_Rhamnus catharticus_), and the white willow (_Salix alba_). + +The moth is not uncommon, and is on the wing in June. + + +Family--ENDROMIDAE + +_The Kentish Glory_ (_Endromis versicolor_) + +The beautiful Kentish Glory is the only British representative of its +family. The male is shown in Plate X (fig. 7); the female is larger and +similarly marked, but its colours are not so bright. + +This moth is not common, but may be seen occasionally in the birch woods +of the southern counties. The males fly rapidly in the bright sunshine, +but the females must be searched for on the bark and branches of the +trees. + +The eggs are laid in April on the twigs of the birch (_Betula alba_), +and the young caterpillar emerges early in May. It is gregarious at +first, but loses its social tendencies as it gets older. When full +grown, it is of a pale green colour, with white spiracles, a dark green +line down the back, and an oblique white stripe on each side of each +segment. The sides are dotted with black and brown, and there is a +conspicuous hump on the top of the twelfth segment. + +When fully grown it spins a cocoon among the dead leaves beneath the +tree, and in this it spends the winter months in the chrysalis state. + + +Family--SATURNIIDAE + +_The Emperor Moth_ (_Saturnia pavonia_) + +Here is another family with but one British member; but in this, as in +the last case, the only representative is a really beautiful insect. The +male _Pavonia_ is shown on Plate X (fig. 8), and will need no written +description as an aid to its identification. The female is larger, and +similarly marked, but the ground colour of the wings is pale grey. + +This moth is abundant almost everywhere, and may be looked for in the +neighbourhood of heaths and woods early in the month of May. + +The larva feeds on a large number of plants and trees, among which may +be mentioned the willow (_Salix alba_), blackthorn (_Prunus spinosa_), +elder (_Sambucus nigra_), whitethorn (_Crataegus oxyacantha_), bramble +(_Rubus fruticosus_), heaths (_Erica tetralix_ and _E. cinerea_), and +the meadow-sweet (_Spiraea ulmaria_). Its colour is a lovely green; and +each segment has several pink tubercles, each surrounded by a black +ring, and giving rise to a tuft of short black hairs. The spiracles are +orange. + +In the autumn it spins a pear-shaped cocoon of silk, open at the small +end (fig. 28). + +It may here be mentioned in passing that, in the case of some of the +larger moths of the few preceding families, the young entomologist is +likely to meet with larvae more frequently than the perfect insect. These +moths, however, are mostly very hardy and easily reared; and a beginner +cannot do better than endeavour to obtain either ova or larvae, in order +that he may be able to watch the different species through their various +stages. + + +Family--DREPANULIDAE + +We now reach a family containing six small moths that differ in many +important particulars from those we have just been considering. They are +of such slender build that a beginner may easily mistake them for +Geometers. Their wings, though small, are broad, and well proportioned +to their bodies. In five cases out of the six the front wings are more +or less hooked at the tips, and on this account the moths in question +are called the Hook Tips. + +The larvae are not hairy, but they all have little fleshy projections on +their backs. Their bodies also taper to a point behind, and the last +pair of claspers are wanting, so that they have only fourteen walking +appendages. When at rest they usually fix themselves by their claspers +only, their pointed 'tails' being directed slightly upward, and all the +front segments being also elevated. When about to change, they descend +to the ground, and spin their cocoons among dead leaves. + +Two only of this family can receive an individual notice. + + +_The Oak Hook Tip_ (_Drepana binaria_) + +This can hardly be described as a very common moth, but it is fairly +plentiful in the woods of the southern counties of England. + +Its wings are yellowish brown, marked with two lighter transverse lines. +There are two black spots between the lines of the fore wings. The +antennae of the male are pectinated; those of the female simple. The +latter sex is further distinguished by the paler colour of the hind +wings. + +[Illustration: FIG. 129.--THE OAK HOOK TIP.] + +The larva is brown, with a broad stripe, edged with yellow, down the +back. There are two projections on the back of the fourth segment. It +feeds on oak (_Quercus Robur_) and birch (_Betula alba_). + +This moth is double-brooded, and may be seen on the wing in June and +August. The larva may be beaten from the above-mentioned trees in June +and July, and again in September. + + +_The Chinese Character_ (_Cilix glaucata_) + +The fore wings of this species are white, with a broad dark blotch from +the inner margin to near the costa. The central portion of this blotch +is marked with silvery spots which are said to resemble Chinese +characters. The hind margin is shaded with a dark grey border, inside +which is a row of dark spots. The hind wings are clouded with grey. + +[Illustration: FIG. 130.--THE CHINESE CHARACTER.] + +This moth is widely distributed, and seems to be common throughout +England. It is double brooded, the first brood appearing in May and +June, and the second in August. + +The caterpillar, which is brown, with two prominent tubercles on each of +the third and fourth segments, feeds on the whitethorn (_Crataegus +oxyacantha_), and the blackthorn (_Prunus spinosa_). + + +Family--DICRANURIDAE + +The five British species that represent this family are such interesting +insects that we should like to have given a detailed description of all +of them, but our limited space will allow of no more than an outline of +the general characteristics of the group and a selection of two for +individual mention. + +They are thick-bodied moths, and the prevailing colours are white and +shades of grey. The antennae are pectinated in the males, and, with the +exception of the Lobster Moth (_Fagi_), in the females also. + +The larvae, like those of the last family, have no anal claspers, and +stand, when at rest, with both ends of the body raised. They have two +'tails' projecting from the last segment. The largest of them (the +Puss), and three smaller species (Kittens) that closely resemble it in +habits, all construct hard cocoons to be presently described; but the +larva of the Lobster Moth spins a light cocoon among the leaves of +trees. + +They all spend the winter in the chrysalis state. + + +_The Poplar Kitten_ (_Dicranura bifida_) + +Our illustration shows the arrangement of the white and grey on the +wings of this moth, but the other Kittens (_Bicuspis_ and _Furcula_) so +closely resemble it that it is necessary to point out a mark of +distinction. It will be observed that the fore wings are crossed by a +broad grey band, edged with black. This band, in the present species, is +almost of the same width throughout, its interior margin being almost +straight, and the exterior one slightly concave. In _Furcula_, the outer +margin of the band is generally sharply bent inward just below the +costa. In _Bicuspis_ the grey band varies considerably in shape, but +both this and the dark blotch near the tip of the wing are more sharply +defined than in the other two species. + +[Illustration: FIG. 131.--THE POPLAR KITTEN.] + +The caterpillar is green, dotted with brown, and has a brown stripe on +the back. This stripe is broken on the third segment, and widens out on +the eighth and thirteenth segments. It feeds on the Poplar (_Populus +nigra_) and Aspen (_P. tremula_). + +When full grown it descends to the trunk of the tree, and constructs a +very hard cocoon of a glutinous substance from its own body mingled with +little pieces of the bark that it removes for the purpose. Thus made, +the cocoon so closely resembles the surrounding bark that detection is +very difficult. I have frequently found these cocoons on the inner +surface of loose bark. + +This moth is widely distributed, and may be searched for in June and +July. The larva feeds during August and September. + + +_The Puss_ (_Dicranura vinula_) + +No written description is necessary in this case, the illustration +easily serving for identification. This beautiful moth flies in May and +June, and is common everywhere. + +[Illustration: FIG. 132.--THE PUSS MOTH.] + +The caterpillar is a very interesting creature. It is green, with a hump +on the fourth segment, and a patch of brown from the fourth segment to +the tail. This patch is very wide on the eighth segment, but tapers to a +point on the thirteenth. The two horns are rather long and rough, and +from each of them a very slender pink filament is protruded when the +caterpillar is irritated. + +It constructs a cocoon very similar to that of _Bifida_, though of +course larger, on the bark of the tree on which it fed, generally three +or four feet from the ground. It feeds on sallows, willows, and poplars, +and may be found during July and August. + + +Family--NOTODONTIDAE + +_The Coxcomb Prominent_ (_Lophopteryx camelina_) + +The family _Notodontidae_ contains several moths of somewhat varied +appearance, but foremost among them are the 'Prominents,' distinguished +by a conspicuous projection on the inner margin of the fore wings. + +[Illustration: FIG. 133.--THE COXCOMB PROMINENT.] + +Our example of this group is the Coxcomb Prominent. + +Its fore wings are brown, with darker markings arranged as shown in the +illustration; and the hind margins are scalloped. The hind wings are +much paler, with a dark brown patch in the anal angle. + +The caterpillar is green, with a yellowish line on each side. The +spiracles are black, and there are two small humps on the twelfth +segment. It feeds during August, September, and October, on various +trees, including the oak, birch, poplar, hazel, and alder. + +The moth flies from June to August, and is moderately common and widely +distributed. + + +Family--PYGAERIDAE + +_The Buff Tip_ (_Phalera bucephala_) + +The first of our two examples of this small family is the common and +destructive Buff Tip. The perfect insect is represented on Plate X, fig. +9, and is too well known to require a lengthy description. During June +and July it may be seen resting on the bark of trees almost everywhere, +with its wings folded closely round its body, and its antennae tucked +under the wings, looking just like a piece of stick, or a projection of +the bark on which it sits. + +[Illustration: FIG. 134.--THE LARVA OF BUCEPHALA.] + +The caterpillars appear towards the end of June, and may be seen in +dense clusters on lime and other trees, sometimes twenty or thirty +huddled together on a single leaf. As they grow larger they retain their +gregarious tendencies, and often completely strip the leaves from large +branches. They are of a dull yellow colour, hairy, and have seven broken +black lines, one along the middle of the back, and three on each side. +The head and legs are black. + +When full grown, they descend to the root of the tree, burrow into the +soil, and there remain in the chrysalis state till the following June. +The chief food plants of this species are the lime (_Tilia vulgaris_), +elm (_Ulmus campestris_), and hazel (_Corylus Avellana_). + + +_The Chocolate Tip_ (_Pygaera curtula_) + +This species is not nearly so common as the last, but is to be met with +more or less in most of the English counties in the month of May. + +Its fore wings are light greyish brown, crossed with four transverse +paler streaks, and tipped with a patch of chocolate brown. The hind +wings are pale yellowish grey. + +[Illustration: FIG. 135.--THE CHOCOLATE TIP.] + +The young caterpillars feed in companies between leaves which they have +spun together, but when nearly full grown they cease to be gregarious. +They are also very different in appearance at different ages. When fully +fed, the larva is of a reddish-grey colour, spotted with black, with a +double row of orange-coloured warts on each side. There is also a little +black hump on each of the fifth and twelfth segments. + +The food plants of this species are sallows (_Salix caprea_ and _S. +cinerea_), poplar (_Populus nigra_), and aspen (_P. tremula_). + + +Family--CYMATOPHORIDAE + +This, the last family of the _Bombyces_, contains seven species of +moderate size, the larvae of which are either quite smooth or have small +warty prominences. The seven species are grouped into three genera, from +two of which we shall select a representative. + + +_The Peach Blossom_ (_Thyatira Batis_) + +The popular name of this pretty little moth is given on account of the +resemblance of the pink patches of its olive-brown fore wings to the +petals of the peach flower. It is a moderately common moth, widely +distributed in England and Ireland, and flies during June and July. + +[Illustration: FIG. 136.--THE PEACH BLOSSOM.] + +The caterpillar is marbled with reddish grey and brown, and has a hump +on the third segment, and a smaller prominence on each of the segments +six to ten inclusive. It feeds on the bramble (_Rubus fruticosus_) +during August and September, and spends the winter in the chrysalis +state, inclosed in a loose cocoon among the dead leaves at the root of +its food plant. + + +_The Yellow-horned_ (_Asphalia flavicornis_) + +This is one of the earliest of our moths, appearing on the wing in +March, when it may be attracted by means of sugar placed on the bark of +the birch (_Betula alba_). + +[Illustration: FIG. 137.--THE YELLOW-HORNED.] + +The wings are grey, with a decidedly greenish tinge, crossed by three +dark lines near the base, and two others, which are zigzag, just outside +the centre. Between these two sets of lines is a conspicuous round pale +spot. The hind wings are greyish brown, darker along the hind margin. + +The larva, which feeds on the above-named tree, is pale greenish, with +both white and black dots. It rolls itself up in a leaf, and seldom +ventures out of the retreat thus formed. It is fully fed in July or +August. + + + + +CHAPTER XIX + +_THE NOCTUAE_ + + +We have already noticed that several of our moths fly by day; that some +come out of their hiding places at dusk, and settle down again to rest +before the deepest shadows of night fall; and that others prefer the +darkest hours of the night. The tribe of moths we are next to consider +includes the greater number (about three hundred) of our truly nocturnal +species, hence the name that heads this chapter. + +They are generally of a somewhat dingy appearance, the prevailing +colours being dull shades of grey, drab, and brown. So closely, in fact, +do certain of them resemble each other, that the greatest care has to be +exercised in the identification of species--a task that is rendered +still more difficult by the variations that we observe in the tints and +markings of certain species. + +These moths have generally rather stout bodies. Their fore wings are +somewhat narrow, and, when the insects are at rest, these are brought +close to the body, and the hind pair are folded up beneath them. + + +Family--BRYOPHILIDAE + +_The Marbled Beauty_ (_Bryophila Perla_) + +Our first family--the _Bryophilidae_--contains only four British species. +These are small and slender-bodied moths, whose larvae feed in early +morning on the lichens that cover stones and old walls, and conceal +themselves by day in holes and chinks and under stones. + +The Marbled Beauty is the only moth of this family that may be +described as common with us. It is abundant in nearly every English +county, as well as in parts of Scotland and Ireland. + +[Illustration: FIG. 138.--THE MARBLED BEAUTY.] + +Its wings are very pale grey, marked with a darker bluish grey, as shown +in the engraving. These markings are variable, but the bases of the fore +wings have always a dark blotch, followed by a patch of pale grey or +white, extending the whole width of the wing. The moth may be found from +the beginning of July to the middle of September. + +The larva feeds from February to April. It is black above, with a broad +orange-bordered stripe down the back; and its body is covered with small +warts, each of which bears a single hair. + + +Family--BOMBYCOIDAE + +In this family there are sixteen British moths, several of which are +exceedingly common. They are much larger than the _Bryophilidae_, and of +a much stouter build. The larvae are covered with little hair-bearing +warts, and are, indeed, often so hairy that they may be mistaken for the +caterpillars of the _Bombyces_. + + +_The Grey Dagger_ (_Acronycta Psi_) + +This is the commonest of all the _Bombycoidae_. It may be found at rest +on tree trunks and palings during the daytime throughout the summer. Its +fore wings are pale grey, with four conspicuous black marks, one of +which--that in the anal angle--resembles the Greek letter _psi_ ([psi]) +placed sideways. + +[Illustration: FIG. 139.--THE GREY DAGGER.] + +The larva is black or very dark grey, with a pale yellow line down the +back, and a black hump on each of the fifth and twelfth segments, that +on the fifth being much larger than the other. It feeds in the autumn on +lime (_Tilia vulgaris_), blackthorn (_Prunus spinosa_), whitethorn +(_Crataegus oxyacantha_), fruit trees, and various other trees, shrubs, +and herbs. + +The moth called the Dark Dagger (_Tridens_) is hardly to be +distinguished from _Psi_. It is not really any darker, and its markings +are almost exactly similar; but the larva is very different. + + +_The Poplar Grey_ (_Acronycta megacephala_) + +This is also a very common moth, to be found in all the southern and +midland counties, wherever poplars abound, during June and July. + +[Illustration: FIG. 140.--THE POPLAR GREY.] + +Its fore wings are grey, marbled with a very dark grey. A little inside +the middle of these wings, near the costa, is a round spot with a dark +centre. This spot is represented in a large number of the _Noctuae_, and +is known as the _orbicular_. It will be observed that in the present +species it is very distinct. + +The caterpillar is dark grey, with a line of black dots down the back; +and it has a number of little warts, bearing hairs. On the back of the +eleventh segment is a rather large pale spot. It feeds during August on +various species of poplar, and changes to a chrysalis in a crevice of +the bark. + + +_The Figure of Eight_ (_Diloba caeruleocephala_) + +The fore wings are brownish grey. Near the middle of the wing, but +nearer the costa than the inner margin, are two whitish spots that +resemble the figure 8. The hind wings are dull brownish grey, with +darker wing rays, and a dark spot near the centre. + +[Illustration: FIG. 141.--THE FIGURE OF EIGHT.] + +This moth is common in all parts, and flies during September. + +The caterpillar emerges from the egg in spring, and is fully grown in +May or June. It is of a very pale colour--yellowish or greenish--with a +broad and broken yellow stripe down the back, and a bluish or greenish +stripe on each side. Its head is blue (hence the specific name) with two +black spots. It feeds on the hawthorn (_Crataegus oxyacantha_) and +various fruit trees; and on the twigs of these (especially the hawthorn) +the little clusters of eggs may be seen during the winter. + + +Family--LEUCANIIDAE + +In this family we have a number of rather small moths, with, generally, +no markings on their wings, save, perhaps, a few dots or streaks. + +Their larvae feed principally on grasses and reeds, and change to the +chrysalis state either in a cocoon among the food plants, or under the +surface of the ground. + +Several of these insects are very common, and most of them abound in +fens and marshes. + + +_The Brown-line Bright-eye_ (_Leucania conigera_) + +The fore wings are yellowish brown. The 'brown line' is a transverse +line parallel with the hind margin, and distant from it about one-fourth +the length of the wing. Another dark brown line, describing a sharp +bend, passes across the wing near the base. The 'bright eye' is a light +spot just outside the centre of the wing, nearer the costa than the +inner margin. This is another of those marks that occur very constantly +in the wings of the _Noctuae_. It lies beyond the _orbicular_ spot, and +is usually somewhat kidney-shaped, and is consequently named the +_reniform_. + +[Illustration: FIG. 142.--THE BROWN-LINE BRIGHT-EYE.] + +The caterpillar is yellowish or greyish, with a pale dorsal line edged +with black. On each side of this is a broad black line, below which is a +yellow line edged with black, then a whitish stripe, next a yellow line +edged with black on the upper side, and lastly a broad brownish line, +just above the spiracles, edged with black on both sides. It feeds on +couch grass (_Agropyron repens_) and various other grasses, and is fully +grown in May. + +The moth flies in July and August, and is common throughout the United +Kingdom. + + +_The Smoky Wainscot_ (_Leucania impura_) + +This same genus includes a number of moths, very similar in general +appearance, and popularly known as the 'Wainscots.' Of these we shall +take two examples. + +The first is the Smoky Wainscot, so called from the dark smoky tint of +the hind wings. Its fore wings are wainscot brown, with lighter rays; +and they each have three black dots arranged in the form of a triangle, +one in the centre, and the other two between this and the hind margin. + +[Illustration: FIG. 143.--THE SMOKY WAINSCOT.] + +The caterpillar is yellowish, with a fine white line down the back. The +spiracles are red, and inclosed in black rings. It feeds on sedges +(_Carex_) from March to May. + +The moth is on the wing from June to August. + + +_The Common Wainscot_ (_Leucania pallens_) + +This moth is very much like the last. The fore wings exhibit the same +three dots, but it may be distinguished by the pale colour of the hind +wings. + +[Illustration: FIG. 144.--THE COMMON WAINSCOT.] + +The larva feeds on various grasses in March and April. It is of a +pinkish grey colour, with two rows of black dots on each side of the +dorsal line. There are also three stripes along the side, two of which +are brownish and the other grey. + +The moth is common everywhere from June to August. + + +_The Bullrush_ (_Nonagria arundinis_) + +Our last example of this family is the Bullrush, a moth that is common +in all parts where its food plant abounds. + +It is much larger than the two preceding species. The fore wings are +yellowish brown, with three parallel transverse lines of black spots. +The hind wings are whitish, tinged with brown near the hind margin. + +[Illustration: FIG. 145.--THE BULLRUSH.] + +The caterpillar is of a dull pinkish colour, with a shining brownish +plate on the second segment. The spiracles are black. It feeds inside +the stems of the reed-mace (_Typha latifolia_), and changes to a +chrysalis within the gallery it has excavated, after making a hole +through which it can escape when it attains the perfect form. + +The caterpillar may be found in May and June, the chrysalis in August, +and the moth in September. + + +Family--APAMEIDAE + +This large family contains no less than forty-four British species, many +of which are exceedingly common; and of the others only about half a +dozen can be regarded as rare. + +Most of them are of medium size, and with one or two exceptions are +dressed in rather dingy garbs; but, although the ground colours are +dull, the various markings of the wings are sharply defined. They may be +searched for on palings and the bark of trees by day, at which time they +repose with their wings sloping like the sides of the roof of a house. +Some are easily attracted by lights, and others partake freely of the +entomologist's 'sugar.' + +The larvae have small retractile heads, and feed on low-growing plants, +keeping themselves well concealed on the lower leaves close to the +ground. + + +_The Frosted Orange_ (_Gortyna Ochracea_) + +We commence with one of the brightest members of the family, the Frosted +Orange. Its fore wings are dark yellow or ochreous, with distinct brown +markings, the chief of which are two broad transverse bands. The +orbicular spot is pale yellow and very distinct. The hind wings are +dingy yellow. This moth flies from July to September, and is easily +attracted by a light at night. It is common everywhere. + +[Illustration: FIG. 146.--THE FROSTED ORANGE.] + +The larva is yellow, dotted with black, with a brownish plate on the +second segment. It feeds inside the stems of a number of plants, +including the marsh thistle (_Cnicus palustris_), musk thistle (_Carduus +nutans_), burdock (_Arctium minus_), mullein (_Verbascum thapsus_), +foxglove (_Digitalis purpurea_), and elder (_Sambucus nigra_). When +about to change to the chrysalis it eats _nearly_ to the surface of the +stem, leaving only a very thin and transparent layer of the epidermis to +cover the hole through which it is to escape when it becomes a moth. + +The caterpillars are to be found in June, and the chrysalides in July. + + +_The Flame_ (_Axylia putris_) + +This also is a pretty insect, but much smaller than _Ochracea_. It is +common in most parts, and may be seen flying in weedy and waste grounds +at dusk during June and July. + +[Illustration: FIG. 147.--THE FLAME.] + +The fore wings are pale pinkish brown, with dark brown along the costa, +and two patches of the same colour on the hind margin. There is also a +double line of small brown dots parallel with the hind margin. + +The larva is brown, with one yellow and two white dots on each segment. +There is also a triangular dark patch on each of the fifth and sixth +segments. It feeds during August on the stinging nettle (_Urtica +dioica_), and various other low herbs. + + +_The Light Arches_ (_Xylophasia lithoxylea_) + +The fore wings of this species are very light ochreous, with a light +brown patch on the middle of the costa, and patches of the same colour +along the hind margin; also a row of small black dots parallel with the +same margin. The hind wings are pale ochreous: they are brownish along +the hind margin, and have a light fringe. + +[Illustration: FIG. 148.--THE LIGHT ARCHES.] + +The moth is very common in waste places, and flies in June and July. + +The caterpillar is of a dirty white colour, dotted with black, and has a +black head. It feeds on the roots of grasses in May. + + +_The Flounced Rustic_ (_Luperina testacea_) + +The fore wings are greyish brown, with darker umber-brown markings. +These latter are variable, but the most conspicuous is a series of dark +crescent-shaped spots almost parallel with the hind margin, and +immediately outside these is a series of paler crescents. + +[Illustration: FIG. 149.--THE FLOUNCED RUSTIC.] + +The caterpillar is dull flesh-colour, with a brown head, and a brownish +plate on the second segment. It feeds on the stems of grasses. + +The moth is common throughout the British Isles, and flies in August and +September. + + +_The Cabbage Moth_ (_Mamestra Brassicae_) + +Whatever be your methods of moth collecting, you are sure to meet with +_Brassicae_ in abundance. They swarm round the insect hunter's sugar in +such numbers as to become a positive nuisance. They are also attracted +by light. During the day they may be seen at rest on palings. The +caterpillar is even better known, and with reason, for it is fearfully +destructive to our vegetables and even our flower beds. It burrows into +the hearts of cabbages, filling the galleries it makes with its +excrement, often leaving no very visible outward signs of its presence +within. But its ravages are by no means confined to cabbages. It eats +with more or less relish almost every vegetable and flowering plant of +our gardens, and is equally partial to the various herbs of the field. + +[Illustration: FIG. 150.--THE CABBAGE MOTH.] + +The fore wings of the moth are dingy brownish grey, marbled in a very +confused manner by darker markings. The _reniform_ spot is very +distinct, the orbicular less so. A light zigzag line runs parallel with +the hind margin. It flies in June and July. + +The larva feeds later in the season, and changes to the chrysalis +beneath the soil in the autumn. It is of a dark grey colour, with a +darker line on the back, and a lighter one along the spiracles, which +are white. + + +_The Dot_ (_Mamestra Persicariae_) + +The conspicuous white reniform spot on the very dark marbled fore wings +is always sufficient for the identification of this species. + +This moth is out in June and July; and during the latter month lays its +eggs on the elder (_Sambucus nigra_), and the various low plants that +supply the larva with food. + +[Illustration: FIG. 151.--THE DOT.] + +The larva is greenish or greyish, sometimes with a reddish tinge, with a +light line down the back. The twelfth segment is humped, and there are +dark V-shaped marks on the back of segments five to twelve inclusive. It +is full grown in September, and burrows into the ground to undergo its +change to the chrysalis, in which state it remains throughout the +winter. + + +_The Rustic Shoulder-knot_ (_Apamea basilinea_) + +The fore wings of this species are pale ochreous grey, with light brown +markings; and there is a short dark streak in the middle of the base, +from which feature the specific name (_Basilinea_) is derived. The hind +wings are of a similar colour, but shading into a dark smoke colour at +the hind margin. + +[Illustration: FIG. 152.--THE RUSTIC SHOULDER KNOT.] + +The caterpillars feed at first on the grains of wheat, on the ears of +which the moth deposits the eggs in June. At harvest time they remain +hidden among the husks, and are often threshed out in large numbers by +the blows of the flail. The cold weather soon overtakes them, and they +then spin a cocoon in which to pass the winter. On the approach of +spring they come out again, and feed by night on various low plants, +hiding themselves among the roots by day. In March they are full grown, +and change to brown chrysalides beneath the surface of the ground. + +The moth flies in June, and is one of the commonest and most destructive +of our _Noctuae_. + + +_The Marbled Minor_ (_Miana strigilis_) + +The next three genera (_Miana_, _Phothedes_, and _Celaena_) include seven +small moths known as the 'Minors.' The commonest of them is the Marbled +Minor, which is to be found in abundance everywhere during June and +July. + +[Illustration: FIG. 153.--THE MARBLED MINOR.] + +This species is very variable, but the fore wings are usually dark +brown, marbled with a lighter colour--white or grey. There is generally +an irregular white or pale grey band crossing the wings parallel with +the hind margin, and two white marks on the inner margin, halfway +between this band and the base. There is also a deep black blotch across +the middle of the wing. + +The caterpillar is greyish or greenish with paler lines and black +spiracles. It feeds on grasses in March and April, and changes to a +chrysalis under the ground in May. + + +Family--CARADRINIDAE + +There are only ten British species in this family, two of which are +rare; and most of the others are particularly dingy. The transverse +lines so often seen on the fore wings of Noctuae are generally well +marked. The larvae have short stiff bristles, and feed on low plants; +they undergo their changes in an earthen cocoon under the ground. + + +_The Mottled Rustic_ (_Caradrina Morpheus_) + +We select as our type of this family the Mottled Rustic--a common moth +that may be procured from June to August. Its fore wings are brownish +grey, with darker lines and spots; the hind wings are almost white, but +darker at the tip. + +[Illustration: FIG. 154.--THE MOTTLED RUSTIC.] + +The caterpillar is brownish grey, with a row of triangular spots on each +side of the back. It is very sluggish, spending the greater part of its +existence among the roots of low plants. It feeds throughout the winter, +except during severe weather, and is full grown in April. The food +plants include teasels (_Dipsacus pilosus_ and _D. sylvestris_), hedge +bedstraw (_Galium Mollugo_), orpine (_Sedum Telephium_), sallows +(_Salix_), and various other plants. + +The chrysalis may be dug out in May. + + +Family--NOCTUIDAE + +A glance at our list of British _Noctuae_ (Appendix I) will show that +this family contains nearly fifty species and only three genera. It +includes several very common moths that frequent our gardens and are to +be met with during almost every summer evening ramble. + +Most of the species are very dingy, but the half-dozen that comprise the +genus _Triphaena_ are characterised by the bright colouring of the hind +wings. The fore wings are narrow and more or less glossy, and overlap to +a greater or less extent when the insects are at rest; and the hind +wings are folded and completely hidden beneath them. + +The larvae are rather thick and smooth, and generally of very dingy +colours. They feed on low plants, often confining their ravages to the +roots, and generally lie well concealed close to the ground or under the +surface. + +The pupae are brown, smooth, and shining, and are usually inclosed in +earthen cocoons. + +We shall briefly notice a few members of each of the three genera. + + +_The Turnip Moth_ (_Agrotis Segetum_) + +This is another of those destructive insects that attack vegetable and +flower gardens, often doing so much damage to our crops as to become +quite a nuisance to cultivators. + +The moth is decidedly dingy. Its fore wings are brown, clouded with a +darker tint. The hind wings are almost white, sometimes with a brown +hind margin. + +[Illustration: FIG. 155.--THE TURNIP MOTH.] + +In June it lays its eggs on the stems of young plants, generally very +close to the ground. As soon as the young caterpillars emerge they +commence feeding on the lower parts of the stems, or burrowing deeply +into the larger succulent roots. When the larvae have completed their +work of destruction in this way, they change to brown chrysalides in the +ground. Some undergo this change in October, and shortly after give rise +to a second brood of moths; but most of them remain in the caterpillar +state throughout the winter, and, contrary to the general rule with +hybernating larvae, continue to feed almost throughout the winter months, +and change to the chrysalis in the following May. + +The caterpillar grows to a large size. It is of a greyish or greenish +colour, with a paler line on the back, a light brown line on each side +of this, black spots between these lines, and black spiracles. + + +_The Heart and Dart_ (_Agrotis Exclamationis_) + +The destructive work of _Segetum_ is assisted by similar operations of +the Heart and Dart, the larva of which feeds voraciously on the roots of +several of our cultivated vegetables, though the present species does +not entirely confine its ravages to the farmer's crops, but attacks the +roots of many low-growing herbs. + +The fore wings of the moth are light brown, generally with a reddish +tinge. The darker markings include a large and very distinct reniform +spot, a less distinct orbicular, and a conspicuous longitudinal blackish +streak near the base of the wing known as the _claviform_. Beyond the +reniform a curved and zigzag dark line crosses the wing. The hind wings +of the male are very pale, those of the female darker, with a whitish +fringe. + +[Illustration: FIG. 156.--THE HEART AND DART.] + +The moth flies from June to August, and is common everywhere. The +caterpillar feeds in the autumn, and reaches its full size in October; +but it is said to feed at intervals throughout the winter. Its colour is +dingy brown or grey, with paler lines on the sides. The spiracles are +black, and there are black dots on the sides. + + +_The Garden Dart_ (_Agrotis nigricans_) + +This is another dingy moth, whose general appearance is so unattractive +that the tyro might be inclined to neglect it. But it must not be +omitted from our selection on that score, for our main object here is to +give the beginner an acquaintance with those species that are most +likely to be captured in the earlier part of his career, and this moth +is certainly one of those that may be described as 'abundant +everywhere.' + +[Illustration: FIG. 157.--THE GARDEN DART.] + +Its fore wings are dull dark brown, often tinged with red, and clouded +with black. The reniform spot is pale, the orbicular spot less distinct, +and between the two there is generally a rhomboidal dark spot. There is +also a short dark streak near the base of the wing, and a black spot +before the orbicular. The hind wings are pale, but smoky towards the +hind margin. + +The caterpillar is brown and shining, with a fine pale line on the back, +and a double white stripe below the spiracles. It is also dotted with +black. It is exceedingly destructive, feeding on clovers (_Trifolium +pratense_ and _T. repens_) and various low plants in May and June. + +The moth flies from June to August. + + +_The Flame Shoulder_ (_Noctua plecta_) + +As our example of the next genus we take the Flame Shoulder, a rather +small moth, easily identified by the broad yellowish-white streak along +the costa of the reddish-brown fore wings. The orbicular and reniform +spots are margined with white, and a thin white streak runs from the +base of the wing to the former. The hind wings are white. This moth +flies in July, and is common throughout Great Britain. + +[Illustration: FIG. 158.--THE FLAME SHOULDER.] + +The caterpillar is reddish brown, with a slender line of white dots on +the back, and a similar line on each side. The body is smooth and +velvety, and is netted and dotted all over with dark brown. It feeds on +the lady's bedstraw (_Galium verum_), sweet woodruff (_Asperula +odorata_), and many other low plants; and is full fed early in July. + + +_The Lesser Broad Border_ (_Triphaena ianthina_) + +We now come to the third and last genus (_Triphaena_) of this extensive +family, a genus which includes six interesting moths, with bright orange +or yellow hind wings. Of these we shall take three examples. + +[Illustration: FIG. 159.--THE LESSER BROAD BORDER.] + +The first of them--the Lesser Broad Border--has fore wings of a rich +reddish or violet brown, with paler markings. The hind wings are bright +orange, with a broad marginal band of black. + +It is a common moth, particularly in the south-western counties, and +flies during July and August. + +The caterpillar is of a dingy yellowish or greenish grey, with a light +line down the back, and two black spots on each side of segments nine to +twelve inclusive. It feeds throughout the winter by night on dead +nettles (_Lamium purpureum_ and _L. album_), primrose (_Primula +acaulis_), whitethorn (_Crataegus oxyacantha_), blackthorn (_Prunus +spinosa_), and various low plants; and may sometimes be seen in flower +gardens. It is full grown in April. + + +_The Lesser Yellow Underwing_ (_Triphaena Comes_) + +This insect is very similar to the last, but is larger. The fore wings +are also of a greyish or ochreous brown, and the black margin of the +hind wings is proportionately narrower. + +[Illustration: FIG. 160.--THE LESSER YELLOW UNDERWING.] + +It is more abundant than _Ianthina_; in fact it is to be found +everywhere in plenty during the month of July. + +The caterpillar is yellowish brown. On the back of each of the eleventh +and twelfth segments are two conspicuous dark marks. The spiracles are +white, and below them is a pale brown stripe. It feeds on the foxglove +(_Digitalis purpurea_), chickweed (_Stellaria media_), thrift (_Armeria +maritima_), and other low plants in the autumn, hybernates during the +winter, and attacks sallows (_Salix Caprea_ and _S. cinerea_) and +whitethorn (_Crataegus oxyacantha_) as soon as the buds appear in the +spring. It is full grown in April, and then changes to a chrysalis on +the surface of the earth. + + +_The Large Yellow Underwing_ (_Triphaena Pronuba_) + +This is by far the commonest moth of the genus, and may be found +everywhere, in town and country, from June to August. It is represented +on Plate XI (fig. 1), but its fore wings are very variable, sometimes a +cold dingy grey, but often of an exceedingly rich and warm brown. On the +costal margin, not far from the tip, there is always a small black spot, +which will serve to distinguish it from _Comes_. + +The caterpillar (fig. 21) feeds throughout the winter on the roots of +almost every plant in our gardens; and, during the warmer weather of the +autumn and spring, on stems and leaves. It is full grown early in the +summer, and then changes to a chrysalis in the ground. Its colour is +dirty yellowish or greenish grey, with a row of dark spots on each +side. + + +Family--AMPHIPYRIDAE + +_The Gothic_ (_Mania typica_) + +The above family contains only four British species, two of which we +shall briefly consider. + +[Illustration: FIG. 161.--THE GOTHIC.] + +The first of these is the Gothic--a very common moth that may be seen +everywhere about midsummer. Its fore wings are brown with darker +marblings, and there are numerous lighter markings which may be easily +made out by reference to the accompanying woodcut. + +The caterpillar is smooth and velvety, of a dull brown or greenish +colour, with darker dorsal and side stripes. The latter are crossed +obliquely by a series of whitish lines. It feeds on fruit and other +trees in clusters when very young in early autumn, and afterwards +descends and feeds on low plants. It hybernates in the winter, and feeds +again on low plants in the spring. When full grown it burrows into the +soil to undergo its changes. + + +_The Old Lady_ (_Mania Maura_) + +This fine moth is so very different from the last in appearance that the +reason for placing the two in the same genus is not apparent till the +earlier stages and life history have been studied. All its wings are +very deep brown; the front pair has a darker band containing the +orbicular and reniform spots, and the hind pair a lighter band across +the middle. + +[Illustration: FIG. 162.--THE OLD LADY.] + +It is a common moth, often to be found at rest by day in outhouses and +sheds. It flies in July and August. + +The caterpillar is dark purple or umber brown, with darker and lighter +markings. It feeds in the autumn on fruit trees, and hybernates during +the winter. In the spring it feeds again on low plants, and changes to a +chrysalis in May under the ground. + + +Family--ORTHOSIIDAE + +This is a large family of over thirty species, most of them of rather +small size, which make their appearance, with two exceptions, either in +early spring or in late autumn, often attracted in the former season by +the sallow blossom, and in the latter by ivy bloom. + +Several of them are very common insects, that are almost sure to be +taken by a young collector during his first season. + +The fore wings of these moths are more or less pointed at the tip, and +the usual lines and spots are generally distinct. The males may be +distinguished from the females by their antennae, which are always more +or less ciliated. + +The caterpillars are smooth and velvety, and feed by night; and the pupae +are inclosed in cocoons constructed of earth and silk. + + +_The Common Quaker_ (_Taeniocampa stabilis_) + +Several of the species of the family are known popularly as Quakers, the +commonest of which--_Stabilis_--is abundant in all parts. + +Its fore wings are grey, with generally either an ochreous or reddish +tinge. The orbicular and reniform spots are outlined with a paler +colour, and there is a pale transverse line parallel with the hind +margin, outside which is a row of indistinct black spots. The hind wings +are greyish brown. + +[Illustration: FIG. 163.--THE COMMON QUAKER.] + +The caterpillar is green and velvety, with a yellowish line on the back +and on each side; and a yellow band crosses the back of the twelfth +segment transversely. It feeds during June and July on oak (_Quercus +Robur_) and elm (_Ulmus campestris_), and changes to a chrysalis in +August on the surface of the ground. In this state it remains throughout +the winter, and the moth emerges in March or April. + + +_The Chestnut_ (_Cerastis Vaccinii_) + +Unfortunately our space will not allow us to notice the whole of even +the very common moths, so, passing over a few with great reluctance, we +come to the familiar Chestnut, which may be seen at large in October and +November, and sometimes even in December, and again appears, after a +rather short period of hybernation, in February and March. + +[Illustration: FIG. 164.--THE CHESTNUT.] + +The fore wings are reddish brown, with darker wavy lines. The orbicular +and reniform spots have pale outlines, and the lower half of the latter +is very dark grey. The hind wings are smoky grey, with generally a pale +band beyond the middle. + +The caterpillar is dark brown, with very indistinct lighter lines. The +spiracles are black, and inclosed in a yellowish grey stripe. It feeds +during June and July on the elm (_Ulmus campestris_), oak (_Quercus +Robur_), and sallow (_Salix caprea_), and various low plants. + + +_The Pink-barred Sallow_ (_Xanthia Flavago_) + +This moth is not nearly so common as the preceding species, but has been +taken more or less in all parts of England. + +Its fore wings are orange yellow, with purplish markings arranged as +represented in fig. 165. The hind wings are yellowish white. + +[Illustration: FIG. 165.--THE PINK-BARRED SALLOW.] + +The caterpillar is brown, with a lateral stripe formed by numerous red, +yellow and white dots. It feeds on sallow (_Salix caprea_) and various +low plants. + +It is full grown in June, and the moth appears in September. + + +Family--COSMIIDAE + +_The Dun-bar_ (_Calymnia trapezina_) + +Our example of this family is the Dun-bar, common everywhere during July +and August. + +Its fore wings are greyish ochreous, with a darker band across the +middle. On each side of this band is a white line margined with dark +grey, and there is a row of black spots along the hind margin. The hind +wings are smoky brown, becoming paler towards the base. + +[Illustration: FIG. 166.--THE DUN-BAR.] + +The caterpillar feeds on oak (_Quercus Robur_), hornbeam (_Carpinus +Betulus_), and birch (_Betula alba_), and may be found in abundance +during May and June. It is green, with dark spots, and white lines on +the back and sides. Although it partakes of the leaves of the +above-named trees, yet its chief food seems to be other caterpillars, +for it devours these with a savage greediness that is simply +astonishing. It will chase an unfortunate caterpillar, seize it by the +neck with a fatal grip, and rapidly devour it. Its chief prey seems to +be the larva of the Winter Moth (_Brumata_). + + +Family--HADENIDAE + +Nearly fifty British _Noctuae_ are included in the family _Hadenidae_. +They are of variable dimensions, and differ much in the brightness of +their colours, some being very dingy, and others gaily tinted. Their +antennae are rather long; and when at rest the wings slope from the back +like the sides of a roof. + +The larvae are smooth, and not very thick; and there is sometimes a hump +on the twelfth segment. The pupae are brown and shiny, and are inclosed +in earthen cocoons beneath the surface of the soil. + + +_The Broad-barred White_ (_Hecatera serena_) + +Although not gaily coloured, this is a pretty little moth, there being a +bright contrast between the white ground and the grey markings of the +wings. It is common in the south of England, and seems to be plentiful +in and around London. + +[Illustration: FIG. 167.--THE BROAD-BARRED WHITE.] + +The caterpillar is of a dingy greenish colour, with a yellowish stripe +on each side of the back; and there are two distinct dots on the back of +each segment. It feeds during July and August on sow-thistles (_Sonchus +oleraceus_ and _S. arvensis_), sleepwort (_Lactuca virosa_), and +hawkweeds (_Hieracia_). + +The moth flies in June and July. + + +_The Marvel-du-jour_ (_Agriopis Aprilina_) + +The Marvel-du-jour is decidedly a beautiful moth--quite an exception +among the _Noctuae_ in this respect, and it is withal both common and +widely distributed. We need not describe it, since it is represented on +Plate XI (fig. 2), and can hardly be mistaken for any other species. + +The caterpillar is dull green, often tinged with red. The dorsal line is +broad and dark, and interrupted by a series of very light lozenge-shaped +spots. It feeds on the oak in May and June, and is full grown in the +latter month. It then burrows into the earth at the foot of the tree, +and there constructs a fragile earthen cocoon previous to changing to a +chrysalis. + +From July to September the chrysalides may be obtained in plenty by +breaking up the sods at the roots of oaks, and the perfect insect may be +found toward the end of September and throughout October. + + +_The Small Angle Shades_ (_Euplexia lucipara_) + +This pretty little moth is represented in fig. 3 of Plate XI. It is very +common throughout the country, and may be seen in June and July. + +The caterpillar is thickest on the twelfth segment, and gradually tapers +from this towards the head. Its colour is pale green, with a white +stripe just below the spiracles, which are black. On each side of the +back are a number of oblique lines, which meet in the middle line, thus +forming a series of V-shaped marks pointing towards the tail. It feeds +on the common bracken fern (_Pteris aquilina_), foxglove (_Digitalis +purpurea_), and the male fern (_Lastraea Filix-mas_), in August and +September. + + +_The Angle Shades_ (_Phlogophora Meticulosa_) + +[Illustration: FIG. 168.--THE ANGLE SHADES.] + +This moth is so common and so widely distributed that it is almost sure +to be taken by the young collector during his first season. Its wings +are scalloped on the hind margin, and their colour light ochreous, often +tinged with pink or olive green, and marked with dark brown as shown in +the illustration. It is double brooded, the first brood appearing in May +and June, and the second in September and October. + +The caterpillar is green or olive brown, and thickly covered with white +spots. It feeds on groundsel (_Senecio vulgaris_) and many other low +plants, the first brood throughout the winter from November to April, +and the second in July and August. + + +_The Grey Arches_ (_Aplecta nebulosa_) + +The fore wings of this moth vary from greyish white to a rather dark +smoky tint. The markings are of a darker colour, and are also subject to +considerable variation. The orbicular and reniform spots are large, and +paler than the ground colour; and several zigzag or scalloped lines, +more or less distinct, cross the wings transversely. + +[Illustration: FIG. 169.--THE GREY ARCHES.] + +The larva is brown, with a lighter line down the back. On each of the +segments five to eleven is a dark lozenge-shaped spot, bisected by the +dorsal line; and on the second segment is a shining plate and a +triangular mark. It feeds on the dock (_Rumex_), and various other low +plants during the autumn; and, after its hybernation, on the leaves of +the sallow (_Salix Caprea_), birch (_Betula alba_), and whitethorn +(_Crataegus oxyacantha_). It is full grown in May, when it burrows into +the ground to undergo its metamorphoses. + +The moth flies during June and July, and is common in nearly every part +of Great Britain. Large numbers may be obtained by searching fences and +tree trunks about midsummer. + + +_The Shears_ (_Hadena dentina_) + +The Shears is another very common moth of the same family. The ground +colour of the fore wings is very variable, but is generally a lighter or +darker shade of grey. Sometimes, however, it has a very decided brownish +tinge. Across the centre of the wing is a darker band, wider on the +costal side, containing the orbicular and reniform spots, as well as a +light patch beneath them, and bordered on each side by a pale zigzag +line. There is another similar line near to and parallel with the hind +margin. The hind wings are smoky grey or smoky brown, darker towards the +hind margin. + +[Illustration: FIG. 170.--THE SHEARS.] + +The caterpillar is greyish, and has a series of triangular black spots +along each side of the back. It feeds on the roots of the dandelion +(_Taraxacum officinale_), and changes to a peculiar spiny chrysalis. + +The perfect insect appears to be abundant everywhere, and is on the wing +in June and July. + + +_The Bright-line Brown-eye_ (_Hadena oleracea_) + +Every collector is sure to meet with this insect during his first +season. The moth is abundant everywhere in June, the caterpillar may be +found feeding in almost every waste and weedy spot in August and +September, and the chrysalis is certain to be turned over by the pupa +digger. + +[Illustration: FIG. 171.--THE BRIGHT-LINE BROWN-EYE.] + +The fore wings of the perfect insect are reddish brown. The orbicular +spot is usually very indistinct, being of almost exactly the same tint +as the ground colour, and surrounded by a very fine whitish line. The +reniform is generally more conspicuous, a portion of it being of a light +ochreous colour. Near the hind margin, and parallel with it, is a white +line, bent sharply into the form of a W, just on the anal side of the +middle. + +The hind wings are greyish brown in the base, and dark smoke colour +towards the margin. + +The caterpillar is pale green or brown, dotted with both black and +white, and adorned with a bright yellow line just below the spiracles. +It feeds on the nettle (_Urtica dioica_), dock (_Rumex_), and many other +low plants; and, according to some observers, on the elm (_Ulmus +campestris_). + + +Family--XYLINIDAE + +The next family--_Xylinidae_--contains twenty British species, several of +which are local, but two or three are abundant and widely distributed. + +The transverse lines that so often cross the wings of the _Noctuae_ are +nearly or entirely absent in this family, and longitudinal lines take +their place. When the insects are at rest the wings are folded rather +closely, the outer pair being arranged like a roof with a very gentle +slope. The bodies of the perfect insects are very stout, particularly in +the thorax, and thus present a rather powerful appearance. + +The larvae are smooth, and generally brightly coloured, and feed +principally on low plants. The chrysalides are generally inclosed in +cocoons on or beneath the ground, and are often provided with spines or +bristles on the under side. + +We shall select two members of this family. + + +_The Early Grey_ (_Xylocampa Areola_) + +One of the first of the _Noctuae_ to greet us in the spring is the Early +Grey, which may be found resting on fences in April, and, if the season +is mild, in March. + +[Illustration: FIG. 172.--THE EARLY GREY.] + +Its fore wings are light grey, often tinged with rose pink, and marked +with dark grey. The orbicular and reniform spots are very distinct, and +surrounded by a pale line; they are both united at their lower edges. +Along the hind margin is a series of dark spots. The hind wings are pale +yellowish grey, with a darker central spot, a central transverse darker +line, and a darker line along the hind margin. + +The caterpillar is yellowish grey. The dorsal line is lighter, and +passes through a brownish spot on the eighth segment. It feeds on the +honeysuckle (_Lonicera Periclymenum_) in July and August, being full +grown towards the end of the latter month. + + +_The Shark_ (_Cucullia umbratica_) + +The Shark is a very common moth, to be found everywhere on palings in +June, but the colour of its wings so closely resembles that of oak and +other light-wood fences that detection is not so easy as with most other +moths. + +[Illustration: FIG. 173.--THE SHARK.] + +The fore wings are grey, and marked with longitudinal dark lines, the +principal of which is a line from the middle of the base to about the +centre of the wing. The wing rays are also darker than the ground +colour. The hind wings are greyish white or brownish grey. + +The caterpillar is very dark brown, with orange spots on the back and +along the spiracles. It feeds on sow-thistles (_Sonchus oleraceus_, _S. +palustris_, and _S. arvensis_) and sleepwort (_Lactuca virosa_) at night +from July to September, and hides during the daytime among the leaves +that lie close against the ground. When disturbed it does not roll into +a ring or feign death like many others of its kind, but wriggles about +most vigorously as if to repel its foe. + + +Family--GONOPTERIDAE + +_The Herald Moth_ (_Gonoptera Libatrix_) + +The above-mentioned family is so called on account of the angular +margins of the wings, especially the fore pair. It contains only one +British species, the Herald (Plate XII, fig. 1), a moth that is common +everywhere in August and September. It hybernates in the perfect state, +and the hybernated specimens may be seen in the spring time, from March +up to the end of May or the beginning of June. + +Its fore wings are reddish grey, thickly spotted and streaked with +brown. Transverse whitish lines divide the base into three parts of +nearly equal widths. The basal and central divisions are tinged with +orange; and there is a small white spot in the base close to the thorax, +also another near the centre of the wing. The hind wings are brownish +grey. + +The caterpillar is green and velvety, with a whitish stripe on the side, +and yellow spiracles. It feeds on willow (_Salix alba_) and sallow +(_Salix caprea_); and when full grown, about the end of June, it spins a +white silken cocoon between leaves of its tree, and changes to a very +dark chrysalis. + + +Family--PLUSIIDAE + +The most peculiar feature of the moths of this family is the tufts of +hair that stand up perpendicularly on the top of the thorax. The abdomen +also is crested, and the fore wings of several species have smooth +patches that display a brilliant metallic lustre. + +Most of the larvae may be described as semi-loopers, for their claspers +number only three pairs, and when they walk their backs are considerably +humped, somewhat after the fashion of the _Geometrae_. Some of them +further imitate the _Geometrae_ in their position of rest, holding on by +their claspers only, with body straightened out at an angle with the +leaf or twig on which they support themselves. + +Unlike the majority of the _Noctuae_, they do not descend to the ground +when about to change, but spin a silken cocoon among the food plants. + + +_The Burnished Brass_ (_Plusia Chrysitis_) + +One of the commonest of the _Plusiidae_ is the Burnished Brass, so called +on account of the large patches of bright golden green on the fore +wings. The hind margin of these wings is very gracefully curved, and +bordered with brown. A brown blotch fills the base of the wing, and the +remaining area is of a beautiful metallic greenish yellow, broken by two +large brown blotches, one on the costal and the other on the inner +margin, which closely approach each other and sometimes meet. + +[Illustration: FIG. 174.--THE BURNISHED BRASS.] + +This moth is very common everywhere, and is one of the frequent visitors +to our flower gardens from June to August. + +The caterpillar is thickest at the twelfth segment, and tapers from this +point. Its colour is pale green. It has no longitudinal stripes on the +back, but each segment is adorned with four or six oblique white marks. +Just above the spiracles is a white stripe. It feeds on the dead nettle +(_Lamium album_), stinging nettle (_Urtica dioica_), and burdock +(_Arctium minus_), and is full grown in June. + + +_The Silver_ Y (_Plusia Gamma_) + +Our second example of this family is the Silver Y, which may be found in +abundance everywhere from June to October. Its fore wings are of a shiny +grey colour, beautifully marbled with a rich dark brown; and just below +the orbicular spot is a brilliant silvery spot, in form something like +the Greek letter [gamma] placed obliquely. The base of the hind wings is +grey; along the margin is a broad and dark smoky brown band, and the +fringe is very light grey, barred with the dark tint of the band. This +moth is commonly driven out of its hiding places among low plants as we +walk in waste places, and when thus disturbed it takes a short and rapid +flight, generally disappearing so suddenly among the herbage that it is +difficult to locate it correctly. + +[Illustration: FIG. 175.--THE SILVER Y.] + +The caterpillar is thickest at the twelfth segment, and tapers gradually +from this point towards the head. Its body is green, with several thin +longitudinal white stripes, and a thin yellow stripe along the +spiracles. It may be found from June to October, feeding on many kinds +of low plants. + + +Family--EUCLIDIIDAE + +_The Mother Shipton_ (_Euclidia Mi_) + +Passing over a few small and less important families, we come to the +_Euclidiidae_, which contains only two British moths. One of these is the +Mother Shipton, a very common insect that flies in June. + +The fore wings of this species are very dark brown with whitish +markings. The latter include a peculiarly tortuous line, the character +of which will be made out more easily from our illustration (Plate XI, +fig. 4) than from a written description. The hind wings are also very +dark brown, and rather prettily spotted with an ochreous tint. + +The caterpillar is pale grey, with four white stripes, and has only +three pairs of claspers. It feeds in May on clovers (_Trifolium +pratense_ and _T. repens_) and other plants. + + +Family--CATOCALIDAE + +This family contains only four British species, but these few are very +striking moths. They are of large size; and, unlike the _Noctuae_ +generally, the chief adornment is reserved for the under wings. When at +rest, the outer or fore wings completely hide the other pair, and then +their general appearance is dull, though if closely examined it will be +observed that these outer wings are really beautifully marbled with +shades of grey. + +The caterpillars of this family are very peculiar creatures. Their +bodies are convex above and flattened beneath; and if disturbed as they +rest on the bark of a tree, instead of leaving their hold and rolling +into a ring like so many other larvae of _Noctuae_, they apply themselves +the closer, and hold on as if to defy our attempts to remove them. +Another peculiarity of these larvae is the possession of fleshy +projections along the sides, just above the legs. They feed on the +leaves of trees, and when about to rest they descend to the trunk, and +there remain protected by their imitative colouring, detection being +rendered even more difficult by the close application of their flattened +under surface to the bark. Before changing to the chrysalis state, they +spin a light cocoon among the leaves or on the bark. + + +_The Clifden Nonpareil_ (_Catocala Fraxini_) + +This is the largest of the family, and, indeed, of all British _Noctuae_. +The fore wings and thorax are light grey, dotted and marbled with darker +grey (see fig. 5, Plate XI); and the thorax and abdomen are banded with +black and greyish blue. + +The young entomologist can hardly expect to meet with this fine insect, +for it is very rare, and it is only occasionally that a specimen is seen +in Britain; but its characteristics are so striking that we have +endeavoured to find it a place here. Reputed British specimens of +_Fraxini_ command the price of a few pounds each, but specimens from the +other side of the Channel may be obtained for a few pence. With such +rarities we should advise a young entomologist to purchase the foreign +specimen rather than adopt the two other alternatives--give an +exorbitant price for a supposed Britisher, or else remain a stranger to +the gem, but all foreign specimens should be labelled according to their +nationalities. + + +_The Red Underwing_ (_Catocala Nupta_) + +The other three members of the family are very similar in appearance, +the fore wings of all being marbled with shades of grey, relieved by +touches of black and brown; and the hind wings, red or crimson, give the +popular names to the species. + +The Red Underwing flies in August and September, and is common in the +southern counties of England, as well as in some of the midland +counties; it may be often seen flying by day around willows. + +[Illustration: FIG. 176.--THE RED UNDERWING.] + +The caterpillar is similar in form to that of _Fraxini_, and when at +rest by day on the bark of its tree it is very difficult to detect, so +closely does it apply itself to the surface, and so perfectly does it +imitate the colour of its surroundings. It feeds on the crack willow +(_Salix fragilis_), sallow (_S. alba_), poplar (_Populus_), and plum +(_Prunus_), and is full grown in June. + + +_The Dark Crimson Underwing_ (_Catocala Sponsa_) + +This beautiful insect is represented on Plate XI (fig. 6). It will be +observed that the black band crossing the centre of the hind wing is +rather broad and sharply bent--an important feature, since it is the +most serviceable distinguishing mark between this species and the Light +Crimson Underwing (_C. Promissa_). + +The caterpillar is similar in form and habits to those of _Fraxini_ and +_Nupta_, and feeds on the oak. It is full fed about the beginning of +June, when it changes to a chrysalis between leaves which it has spun +together with silk. + +The moth flies in July and August, and is common only in certain oak +woods of the southern counties. It is particularly abundant in the New +Forest, where scores may be taken in a single night by judicious +sugaring. + +There yet remain a few small families of the _Noctuae_, but we must leave +them in order that we may give a proportionate share of our space to the +other great division of the larger moths--the _Geometrae_. + + + + +CHAPTER XX + +_GEOMETRAE_ + + +We have already referred (page 28) to caterpillars that walk by a +series of strides, alternately looping and extending their long and +slender bodies. It is this peculiar characteristic of the larvae of +the present division that suggested the name _Geometrae_--a term that +signifies 'earth-measurers,' for they appear to measure the ground +over which they travel in terms of their own length. We have also +dealt with the peculiarities of structure in the case of these +caterpillars--peculiarities which adapt them to this mode of +progression; and we have now to make a selection from the various +families of this important division for a more detailed description. + +The _Geometrae_ include nearly three hundred species and sixteen +families. The moths have slender bodies and full wings, and generally +rest with the latter outspread. A few, however, repose with wings erect +like the butterflies, and a small number conceal their hind wings after +the manner of the _Noctuae_. + + +Family--UROPTERYGIDAE + +_The Swallow Tail_ (_Uropteryx sambucaria_) + +Our first family--_Uropterygidae_--has only one British representative, +and that is the well-known Swallow Tail, so common in gardens and among +hedgerows in the south of England. This species is shown on Plate XII +(fig. 2), and the insect is so readily identified by the conspicuous +'tails' on the hind wings that no written description will be necessary. + +The caterpillar is a most peculiar and interesting creature. Its colour +is very variable, being either brown, olive, ochreous, or reddish; and +it is notched or humped in such a manner that it exactly resembles a +twig. This strange imitation is rendered still more remarkable by the +attitude assumed by the caterpillar when at rest. It fixes itself to a +twig by means of its two pairs of claspers, with its body standing out +at an angle in a perfectly straight posture; but its head is always +supported by means of a very slender and almost invisible silk fibre. It +feeds on a number of plants and trees, including elder (_Sambucus +nigra_), blackthorn (_Prunus spinosa_), whitethorn (_Crataegus +oxyacantha_), bramble (_Rubus fruticosus_), honeysuckle (_Lonicera +Periclymenum_), and forget-me-not (_Myosotis arvensis_). It may be found +feeding in the autumn, or hybernating in the crevices of the bark of +trees in winter. In April or May it comes out again; and in June, in +which month it is full grown, it binds together some fragments of +leaves, and forms them into a little swinging hammock in which it +changes to a brown chrysalis spotted with black. + +Just at this time it seems to be particularly sensitive. In the +caterpillar state it will strongly resent any kind of disturbance, and +will give a blow to an intruder by suddenly swaying its body right and +left; and while in its hammock a gentle irritation, such as a puff of +wind from the mouth, will set it wriggling in a furious manner. + + +Family--ENNOMIDAE + +This family contains about twenty species, several of which rank among +the commonest as well as the most beautiful of the _Geometrae_. Their +wings are more or less angulated; and the antennae are generally +pectinated in the males. + +The larvae are generally humped and twig-like; and, as in the last +species, the semblance is increased by the position they assume when at +rest. The number of limbs varies from ten to fourteen, but where the +claspers exceed two pairs, the additional two or four, as the case may +be, are seldom used in walking. + + +_The Brimstone Moth_ (_Rumia luteolata_) + +As soon as the warm evenings of May set in, this lively and bright +little moth may be seen flitting about among our hedges at sunset; and +it continues with us throughout the whole of the summer, but is +particularly plentiful during the month of June. + +The moth itself need not be described, since it is shown on Plate XII +(fig. 3); but the caterpillar (fig. 25) must receive a passing notice. +It varies considerably in colour, being either green, brown, or marbled +with a mixture of shades of both these colours. It has a hump on the +back of the seventh segment, and two more on the ninth, and possesses +four pairs of claspers. It feeds on whitethorn (_Crataegus oxyacantha_), +blackthorn (_Prunus spinosa_), and the apple (_Pyrus Malus_), and may be +found on these trees throughout the summer. + +Some believe that there are three successive broods of this insect each +year, but it is doubtful whether this is invariably the rule, since both +the moth and its larva are to be found without intermission throughout +the season. + + +_The Light Emerald_ (_Metrocampa margaritaria_) + +All the wings of this moth are very pale green, and crossed with a white +band which is bordered with a darker green on the inner side. The fore +wings have an additional transverse line just halfway between the former +and the base, but this one is not so distinct. It flies in July, and is +very widely distributed, and in some parts is very abundant. + +[Illustration: FIG. 177.--THE LIGHT EMERALD.] + +The caterpillar feeds in September, and again in May, after hybernation, +on several of our forest trees, including the oak (_Quercus Robur_), elm +(_Ulmus campestris_), birch (_Betula alba_), and beech (_Fagus +sylvatica_). It is of a dingy olive colour, with a dark dorsal line, on +each side of which is a row of white spots; and it has three pairs of +claspers. + + +_The Scalloped Oak_ (_Crocallis elinguaria_) + +This species is common and widely distributed, and may be seen flying at +dusk towards the end of July and throughout August. It is represented in +fig. 4 of Plate XII. The antennae of the male are strongly pectinated; +those of the female are simple. + +The caterpillar may be found in the autumn, and again in spring, feeding +on the honeysuckle (_Lonicera Periclymenum_), whitethorn (_Crataegus +oxyacantha_), blackthorn (_Prunus spinosa_), beech (_Fagus sylvatica_), +and various fruit trees. It is full grown in June, when it turns to a +chrysalis in a cocoon spun between leaves or moss on or near the ground. +It is of a greyish-brown or greyish-purple colour, and looks very like a +piece of twig. + + +_The August Thorn_ (_Eugonia quercinaria_) + +Our last example of this family is the August Thorn, represented in the +accompanying woodcut. The fore wings are ochreous yellow, crossed by two +nearly parallel lines of dark brown. In order to distinguish between +this and one or two similar species it must be observed that both these +lines are angulated near the costa, the inner one very sharply so; and +between the two is a distinct brown spot near the costal margin. The +hind wings are paler, and are crossed by an indistinct darker line. The +antennae of the male are strongly fringed; those of the female are +simple. + +[Illustration: FIG. 178.--THE AUGUST THORN.] + +The moth is very common in August and September, and is readily +attracted by lights in the evening. + +The larva is grey, marbled with reddish brown. It has three small humps +on each of the sixth and seventh segments, two on the twelfth, and one +larger one on the ninth. It feeds on the oak and various other trees +during the month of June. + + +Family--AMPHIDASYDAE + +The seven British species of the family _Amphidasydae_ are generally to +be distinguished by their rather stout abdomens, and the long shaggy +hair that covers their thoraces. The antennae of the males are +pectinated, and those of the females simple; and in three cases the +latter sex is wingless. + +The caterpillars have long and slender twig-like bodies, and are never +provided with more than two pairs of claspers. The chrysalides terminate +behind in a sharp spine, and are always to be found buried in the soil. + + +_The Brindled Beauty_ (_Biston hirtaria_) + +Early in April, and sometimes in March, this moth may be seen in +abundance, resting on the lime trees in and around our towns. In fact, +so strongly marked is its partiality to the haunts of man in the +neighbourhood of our great metropolis that it has received the name of +the Cockney. The male is represented in fig. 5 of Plate XII, and the +female may be distinguished from it by her simple antennae and larger +body. + +The caterpillar is coloured with alternate bands of dark purple brown +and reddish brown. There is a yellow band on the front of the second +segment, a row of yellow spots on each side, and two little bright +yellow warts on the back of each segment. It feeds by night on lime +(_Tilia vulgaris_), elm (_Ulmus campestris_), and various fruit trees, +and often appears in such numbers that the foliage is almost completely +devoured. During the daytime it may be seen resting on the bark, almost +invariably fixed longitudinally on the trunk, where it looks like a +natural ridge of the bark which it so closely resembles in colour. It +may be found in June and July, and in August it changes to a chrysalis +at the foot of its tree, just below the surface of the soil. + + +_The Peppered Moth_ (_Amphidasys betularia_) + +Although this common species displays no bright tints, yet it is +prettily marked, its whitish wings being peppered and blotched all over +with black or very dark brown. It flies in May and June, later than any +other species of the family, and may generally be found on fences and +tree trunks during the day. + +[Illustration: FIG. 179.--THE PEPPERED MOTH.] + +The colour of the caterpillar is very variable--drab, grey, green, or +brown; but it may be known by the deep notch in the middle of the head, +and the arrangement of its 'humps.' These latter are only small reddish +or whitish projections, of which there is one on each side of the fifth, +sixth, seventh, eighth, tenth, and eleventh segments; also two on the +back of the ninth and twelfth. It feeds in August and September on a +large number of trees, including, in fact, nearly all our commonest +forest and fruit trees. In September it enters the soil to undergo its +change to the chrysalis. + + +Family--BOARMIIDAE + +In the next family--_Boarmiidae_--there are about twenty British members, +most of which are very pretty moths. They differ generally from the last +family in that their bodies are more slender, and although some of them +bear a resemblance to species of the family _Ennomidae_, their wings are +not angulated. In several cases the fore and hind wings are both +similarly marked, a feature very uncommon with moths. + +The caterpillars of this family usually have humps on the sixth and +twelfth segments only, and have two pairs of claspers. The pupae are to +be found either on the ground, among leaves or moss, or beneath the +soil. + + +_The Waved Umber_ (_Hemerophila abruptaria_) + +The most gaily coloured member of this family is the Waved Umber, shown +in fig. 6 of Plate XII. Like many other _Geometrae_, it rests on fences +and tree trunks by day with wings expanded so that all four are +displayed. It is on the wing in May and early June, and again in August, +and often frequents our gardens at dusk. + +The caterpillar is very dark brown, with a white collar on the front of +the second segment. It feeds in June and July on privet (_Ligustrum +vulgare_) and the cultivated rose trees of flower gardens, and probably +also on the dog rose (_Rosa canina_). When full grown it spins a silken +cocoon in a fork of one of the twigs, and there undergoes its +metamorphoses. + + +_The Willow Beauty_ (_Boarmia gemmaria_) + +Our second example of the _Boarmiidae_ is the Willow Beauty, the male of +which species is here illustrated. Its wings are brownish grey, marked +with dark brown lines and streaks. The female is generally larger than +the male, and has simple antennae. The moth is abundant throughout +England, and may be seen generally resting on fences and trees in June +and July. + +[Illustration: FIG. 180.--THE WILLOW BEAUTY.] + +The ground colour of the caterpillar is much the same as that of the +moth, and is marked with a similar darker tint. It has a yellowish line +along the spiracles, and is much like a piece of brownish twig. It feeds +on the oak (_Quercus Robur_), Birch (_Betula alba_), ivy (_Hedera +Helix_), and other trees, and may be found in September and October. + + +Family--GEOMETRIDAE + +The next family contains eight moths, mostly of small size, all of which +have green wings, and are popularly known as the 'Emeralds.' In most +cases the male may be distinguished by its pectinated antennae. + +There is no general characteristic by which we may know all the larvae, +but some have the head deeply notched. + + +_The Large Emerald_ (_Geometra papilionaria_) + +This species is the largest of the family, and measures over two inches +when its wings are expanded. The colour is dull green, with whitish +bands and spots, the arrangement of which may be seen in our engraving. + +[Illustration: FIG. 181.--THE LARGE EMERALD.] + +The moth is out in July, and is common in most parts of England. + +The caterpillar feeds on birch (_Betula alba_), beech (_Fagus +sylvatica_) and hazel (_Corylus avellana_) in the autumn, and hybernates +while still young. In the spring it feeds again, and is full grown in +June, when it changes to a chrysalis in a cocoon spun between leaves. + + +_The Common Emerald_ (_Hemithea strigata_) + +One of the commonest of the Emeralds is _Strigata_, which may be found +in June and July in all parts of England, as well as in some localities +in Scotland and Ireland. Its wings are of a dull green colour, the front +pair being slightly scalloped on the hind margin, and crossed by +indistinct pale lines; and the hind pair are both scalloped and angled +and crossed in the middle by a transverse pale line. The fringe is +white, dotted with dull reddish brown. + +[Illustration: FIG. 182.--THE COMMON EMERALD.] + +The caterpillar is yellowish green, except the second, third, and fourth +segments which are brownish. It feeds on oak (_Quercus Robur_) and +whitethorn (_Crataegus oxyacantha_), and may be found in June. + + +Family--EPHYRIDAE + +_The Maiden's Blush_ (_Zonosoma punctaria_) + +The family _Ephyridae_ contains only six British species, chiefly +remarkable for the fact that their pupae generally resemble those of +butterflies. + +We choose for our example the pretty little Maiden's Blush, so called on +account of the soft reddish patch on the middle of each fore wing. It is +represented in fig. 7 of Plate XII. It is moderately common, occurring +more or less in all parts of England, as well as certain localities in +the sister countries. It is a double-brooded moth, and may be caught in +May and August. + +The caterpillar feeds on oak (_Quercus Robur_), from which it may be +obtained by beating both in June and September. It is either green or +tawny yellow, marked with yellow oblique lines on the sides. + + +Family--ACIDALIIDAE + +The moths of this family, over thirty in number, are mostly of small +size, and have slender bodies. As a rule the wings are not in the least +angulated or scalloped, but in a few species the hind pair are slightly +angled on the hind margin; and both fore and hind wings are similarly +marked. The antennae are simple in the females, and generally only +slightly ciliated in the males. + +The caterpillars are long and slender, without projections, and feed +principally on low plants. The pupae are to be found in loose cocoons +among the leaves of the food plants or under the soil. + +We shall briefly notice three members of this rather extensive family. + + +_The Lace Border_ (_Acidalia ornata_) + +The wings of this moth are silvery white, marked along the hind margin +with a beautiful lace-like border. This border consists of delicate +black and dark grey lines, and includes, in the fore wing, two light +brown blotches, one near the middle and the other in the anal angle. It +is abundant in England, particularly in chalky districts, but does not +seem to extend into Scotland. It may be seen on the wing from June to +August. + +[Illustration: FIG. 183.--THE LACE BORDER.] + +The caterpillar feeds on thyme (_Thymus Serpyllum_) and marjoram +(_Origanum vulgare_). + + +_The Riband Wave_ (_A. aversata_) + +All the wings of this species are of a pale yellowish or ochreous grey. +The fore wings are crossed by three transverse dark lines, and the hind +wings by two. The space between the two outer lines of the fore wing and +that between the lines of the hind wing are usually filled in with a +greyish brown, thus forming the 'riband' from which the popular name of +the insect is derived; and when this is the case the lines which border +the riband are scarcely distinguishable. Just inside the second line of +the fore wings, near the costa, is a small but conspicuous brown spot. + +[Illustration: FIG. 184.--THE RIBAND WAVE.] + +The moth flies in June and July, and is common in all parts. + +The caterpillar is dark brown except segments ten to thirteen, which are +grey. The line along the spiracles is whitish, and the surface of the +body is roughened by a number of minute warts. It feeds on various low +plants, including the meadow sweet (_Spiraea ulmaria_), water avens +(_Geum rivale_), common avens (_G. urbanum_), and knot-grass (_Polygonum +aviculare_), during April and May. + + +_The Blood-vein_ (_Timandra amataria_) + +Our last example of the _Acidaliidae_ is the Blood-vein, which is common +in most parts of England in June and July. + +[Illustration: FIG. 185.--THE BLOOD-VEIN.] + +Its fore wings are pale grey, dusted with darker grey, and crossed by an +oblique red streak which runs from the tip of the fore wing to near the +inner margin of the hind wing. A slender dark and wavy line lies outside +this one, parallel with it in the hind wing, but meeting it near the tip +of the fore wing. + +The caterpillar is grey, with three white longitudinal stripes. It feeds +in the autumn on dock (_Rumex_), sorrel (_R. acetosa_), and knot-grass +(_Polygonum aviculare_). + + +Family--CABERIDAE + +Six species, all of rather small size, constitute the British portion of +the above family. Their wings are mostly white or pale grey, with light +markings, and without angles. The moths are to be caught with the net +at dusk, or they may be seen on fences and tree trunks during the day, +with their wings fully extended and applied closely to the surface on +which they rest. + +The larvae, which have no humps, feed on trees, and change to the +chrysalis state in light silken cocoons. + + +_The Common Wave_ (_Cabera exanthemata_) + +The first of our two examples of this small family is the Common Wave, +the wings of which are pale grey, almost white, dusted all over with +small dark dots. The fore wings are crossed by three parallel and +equidistant darker transverse lines, and the hind pair by two. The male +may be distinguished by its ciliated antennae. + +[Illustration: FIG. 186.--THE COMMON WAVE.] + +The caterpillar is yellow or greenish yellow, with hinder segments +slightly swollen. It feeds during the latter part of the summer on +sallows (_Salix caprea_ and _S. cinerea_) and alder (_Alnus glutinosa_), +and changes to a chrysalis in a light cocoon among fallen leaves. In +this state it spends the winter, the perfect insect emerging in May or +June. + +This species is very abundant in most parts. + + +_The Clouded Silver_ (_Bapta temerata_) + +The other example is the Clouded Silver, the wings of which are white, +and clouded along the hind margin with smoky grey. On the hind margin of +the fore wings, close to the fringe, is a row of black crescent-shaped +spots; and on the inner side of the cloudings is a waved transverse +band. In the centre of the same wings there is a very distinct dark +spot. + +[Illustration: FIG. 187.--THE CLOUDED SILVER.] + +This moth is not so common as the last, but is widely distributed. It +flies in May and June. + +The caterpillar is bright green on the upper side, and has a row of +orange spots, bordered with brown, down the middle of the back. It feeds +in the autumn on the blackthorn (_Prunus spinosa_) and the wild cherry +(_P. Avium_), and spends the winter in the chrysalis state, inclosed in +a light silken cocoon. + + +Family--MACARIIDAE + +_The_ V _Moth_ (_Halia Vauaria_) + +The family _Macariidae_ contains only five British species, four of which +have the tip of the fore wings extended more or less into an angle, and +the hind wings are also angled to a greater or less extent. + +[Illustration: FIG. 188.--THE V MOTH.] + +Our only example is the V Moth, so called from the conspicuous V-shaped +blackish mark on the middle of the costa of the fore wings. The ground +colour of all the wings is grey, with a delicate violet tinge. There are +other dark markings in addition to the one mentioned above, and the +arrangement of these may be seen in the woodcut. + +This species is very common in all parts, and flies at about midsummer. + +The caterpillar is very variable in colour, but is generally green, and +is marked with longitudinal wavy lines. On each side is a series of +yellow blotches, forming a broken lateral stripe, and the body is +covered with minute black bristle-bearing warts. It feeds in May on +gooseberry and currant bushes, and changes to a chrysalis in a web +between the leaves. + + +Family--FIDONIIDAE + +We now come to a family of moths peculiar for their habit of flying more +or less by day. As is often the case with day-flying moths, these are +mostly prettily marked, and are consequently often mistaken by the +uninitiated for butterflies. Most of them are to be found on heaths, +downs, and open fields; but one--the Bordered White--is met with only in +fir woods. + +The wings are not angulated, and the antennae of the males are +pectinated. + +The larvae are generally to be distinguished by a couple of little horns +on one or more of the hindermost segments, and in most cases they pupate +beneath the surface of the soil. + + +_The Common Heath_ (_Ematurga atomaria_) + +Of this family we shall select two examples, the first of which is the +Common Heath, often so abundant on heaths and downs that they are +disturbed at almost every footstep. + +The ground colour of the wings of the male is a dull yellowish grey, and +that of the female greyish white. In both cases the wings are crossed by +irregular dark brown bands. The fringe is barred alternately with white +and dark brown, and the whole of the ground tint between the +above-mentioned bands is thickly dotted with dark brown. The female is +generally smaller than the male. + +[Illustration: FIG. 189.--THE COMMON HEATH.] + +The caterpillar is very variable in colour, but is generally reddish +brown, ochreous brown, or greenish, with a light line along the +spiracles, and a series of lozenge-shaped spots on the back. It feeds on +trefoils (_Lotus corniculatus_ and _L. pilosus_) and various other +plants that grow on heaths. + + +_The Bordered White_ (_Bupalus piniaria_) + +The male of this species is boldly marked with yellowish white and dark +brown, the arrangement of the two colours being shown in fig. 190. The +female is very different in general appearance. Her wings are of an +almost uniform orange or yellowish-brown tint. The fore wings are darker +near the tip, and there is generally a darker transverse band across the +centre. + +[Illustration: FIG. 190.--THE BORDERED WHITE--MALE.] + +The male may often be seen flying in the sunshine among the branches of +fir trees during May and June, but his mate is rather less active, and +is generally to be secured by beating the branches. + +The caterpillar is pale green, with whitish stripes and yellow +spiracles. It feeds during August and September on the leaves of the +Scotch fir (_Pinus sylvestris_). + + +Family--ZERENIDAE + +_The Currant Moth_ (_Abraxas grossulariata_) + +The family _Zerenidae_ contains only four British moths, and of these we +select the Currant Moth or Magpie. This insect is exceedingly common +everywhere, and on account of its general brightness of appearance, and +also of its diurnal habits, it is often taken for a butterfly. The +ground colour of the wings is creamy white, with a yellow transverse +band, and a yellow blotch at the base; and the whole surface is more or +less blotched with black. + +[Illustration: FIG. 191.--THE CURRANT MOTH.] + +From the end of June to August this moth may be seen in abundance in our +gardens, wherever currant bushes exist, flying about both during the +sunshine and at dusk, with rather a heavy movement. + +The caterpillar is white, with a yellow line along the spiracles, and +numerous black dots. There are, in addition to the dots, two large black +blotches on the back of each segment. It feeds during May on currant and +gooseberry bushes, also on the blackthorn (_Prunus spinosa_). About the +end of May it spins a light silken cocoon, and changes to a short dumpy +chrysalis of a glossy black colour with bright yellow bands (fig. 34). + + +Family--HYBERNIIDAE + +Passing over the family _Ligiidae_, which contains only one British moth, +the Horse-chestnut, we come to the small but interesting family, +_Hyberniidae_. + +Of this we have six species, five of which favour us during the bleakest +months of the year. Two of them visit us in October and November, and +even remain with us up to Christmas. The others follow closely on them, +and may be seen from January to March. + +The males have slender bodies, and their wings are full and without +angles; but the females are either perfectly or nearly wingless. In +three cases there is hardly a trace of wings in this sex, so that they +look more like spiders than moths. + +The caterpillars are long and slender and without humps, and all feed on +the leaves of trees. They change to the chrysalis state under the +ground. + + +_The Spring Usher_ (_Hybernia leucophaearia_) + +Early in February, and often even in January, this moth may be seen in +abundance in almost every oak wood, sitting on the bark of the trees, +or occasionally taking a short flight in the sunshine. In colour it is +very variable. The wings have always a whitish ground marbled and dotted +with dark brown, but in some the fore wings are almost entirely dark +brown with the exception of a transverse central bar. The female has +only the slightest rudiments of wings. + +[Illustration: FIG. 192.--THE SPRING USHER.] + +The caterpillar feeds on the young buds and leaves of the oak (_Quercus +Robur_) and sycamore (_Acer Pseudoplatanus_), concealing itself among +the small leaves which it has spun together. It is full grown in June, +when it changes to a chrysalis on the surface of the ground, and remains +here throughout the summer and part of the following winter. + +The colour of the caterpillar is very variable, but is usually pale +green with white markings. + + +_The Mottled Umber_ (_Hybernia defoliaria_) + +This very pretty moth is represented in fig. 8 of Plate XII. It is very +common in most parts, and visits us at the fall of the leaf, generally +appearing in October, and remaining on the wing till November. Our +illustration gives the usual appearance of the male, but in some +specimens the four wings are all of one uniform reddish-brown colour, +evenly dotted all over with a darker tint. The female is quite wingless. + +The caterpillar is exceedingly pretty. Its head is large and brown. The +back is brown, bordered with a fine black line. Below this is a broad +and bright yellow line, with a red spot on each segment. The spiracles +are white. It feeds during spring on oak (_Quercus Robur_), whitethorn +(_Crataegus oxyacantha_), blackthorn (_Prunus spinosa_), and other trees. +When disturbed it always allows itself to fall for a foot or two, and +then remains swinging at the end of a silken fibre till danger is over, +or hunger recalls it to its food. It changes to a chrysalis on the +ground about the middle of June. + + +_The March Moth_ (_Anisopteryx aescularia_) + +This is another common moth, and should be looked for during March and +April on the barks of trees in oak and other woods. The fore wings are +of a dingy brown colour, paler near the base, and crossed by a pale wavy +line. The hind wings are lighter, with a central dark spot. But this +description applies to the male only, for the female is wingless, and +may be known by the tuft of hair that tips the abdomen. + +[Illustration: FIG. 193.--THE MARCH MOTH.] + +The caterpillar is pale green, clouded with a darker tint, and has a +white line on each side of the back. It feeds in May on the three trees +named for the last species, also on lime (_Tilia vulgaris_) and elm +(_Ulmus campestris_). + + +Family--LARENTIIDAE + +This is by far the most extensive family of the _Geometrae_, containing +as it does considerably over a hundred species, or well nigh a half of +the whole group. + +The wings of the various species are smooth and more or less glossy, and +the front pair are generally crossed by several wavy lines. Many of the +moths, and particularly those known popularly as the Pugs, are very +small. Representatives of the family are to be met with almost +throughout the year--from early spring to the middle of the winter. + +Most of the caterpillars are rather long and slender, and without humps; +and green is the prevailing colour. They feed either on trees or low +plants, often protecting themselves in folded leaves; and some of the +smaller species show a decided preference for flowers and seeds. + +We shall select about a dozen of the commonest members for individual +description. + + +_The November Moth_ (_Oporabia dilutata_) + +Our first example is the November moth--a rather dingy and very variable +species that may be found almost everywhere in October and November. The +ground colour of the fore wings is dingy grey, crossed by several darker +lines, subject to considerable variations. The hind wings are paler, +with two slender darker lines parallel with the hind margin. + +[Illustration: FIG. 194.--THE NOVEMBER MOTH.] + +The caterpillar feeds on many trees, the principal of which are the oak, +whitethorn and blackthorn. Like the perfect insect, it is very variable +in colour, but is generally of a bright green, with reddish or purplish +spots on the back and sides. The spiracles are yellow or orange, and +below them is a white stripe. It is full fed in June. + + +_The Twin-spot Carpet_ (_Larentia didymata_) + +The Twin-spot Carpet is common throughout Great Britain, and the +beginner is likely to meet with it in June and July during his first +season. Our illustration represents the male, the fore wings of which +are greyish brown, crossed by several dark lines, and with a double dark +and conspicuous spot near the middle of the hind margin. The female is +much lighter, and the markings are also lighter and less distinct. + +[Illustration: FIG. 195.--THE TWIN-SPOT CARPET.] + +The caterpillar is pale green, with a narrow whitish line along the +spiracles. It feeds in April and May on the leaves of the wood anemone +(_Anemone nemorosa_), chervil (_Chaerophyllum temulum_), and other +plants. + + +_The Grass Rivulet_ (_Emmelesia albulata_) + +We represent the genus _Emmelesia_ by the Grass Rivulet--a pretty little +moth that flies in June, and which is widely distributed though not +abundant. + +[Illustration: FIG. 196.--THE GRASS RIVULET.] + +Its fore wings are pale grey, crossed by several white lines, the +arrangement of which may be seen in our engraving. The hind wings are of +the same ground colour, but have no markings except a white wavy line +near the hind margin. + +The caterpillar feeds during July and August on the seeds of the yellow +rattle (_Rhinanthus Crista-galli_), protecting itself from its enemies +by spinning together the petals of the flowers; and when full grown it +changes to a chrysalis under the same cover. + + +_The Netted Pug_ (_Eupithecia venosata_) + +We now come to the enormous genus _Eupithecia_, containing about fifty +small species, most of which are known as 'Pugs.' Many of these are +only imperfectly known, there being yet much to learn about their +earlier stages. + +[Illustration: FIG. 197.--THE NETTED PUG.] + +The Netted Pug flies in May and June, and is to be found in most parts +of Great Britain. Its fore wings are brownish grey, crossed by two +zigzag light bands, both of which are bordered with black, and divided +throughout by a fine dark line. There are also other dark lines, both +transverse and longitudinal, arranged as here represented. + +The caterpillar feeds during July inside the seed capsules of campions +(_Silene Cucubalis_, _S. maritima_, _S. acaulis_, and _Lychnis diurna_) +and catchfly (_Silene gallica_ and _S. nutans_). + + +_The Narrow-winged Pug_ (_Eupithecia nanata_) + +Early in May, and frequently in April, this pretty little moth may be +seen flying about at dusk among the heather on our moors. It is one of +the first Pugs of the season, and is widely distributed, and very common +in some localities. + +[Illustration: FIG. 198.--THE NARROW-WINGED PUG.] + +Its wings are dark grey, and marked with several transverse wavy light +lines. The fringe is dark grey, spotted with white. + +The caterpillar feeds during August and September on the ling (_Calluna +vulgaris_) and heath (_Erica cinerea_ and _E. Tetralix_). + + +_The Brindled Pug_ (_Eupithecia abbreviata_) + +Our last example of the Pugs is the Brindled Pug, another early species, +appearing on the wing in March and April. It is common in most parts, +and may generally be easily obtained by searching fences and tree +trunks. + +[Illustration: FIG. 199.--THE BRINDLED PUG.] + +Its fore wings are very long in proportion. The colour is yellowish +brown, crossed by darker lines. The fore wings have a very broad band of +the ground colour, broken by two short lines, and crossed by a slender +angulated stripe. + +The caterpillar feeds on the oak in June. + + +_The Small Seraphim_ (_Lobophora sexalisata_) + +This moth is very much like the Pugs in general appearance, and is quite +as small and even smaller than some of them; but it and the other +members of its genus differ from the Pugs in that they cover their hind +wings when at rest. + +[Illustration: FIG. 200.--THE SMALL SERAPHIM.] + +The fore wings are yellowish or pale brownish grey with four paler +transverse lines, the two median ones of which are divided throughout by +a darker fine wavy line. The hind wings are grey, paler at the base, and +crossed centrally by a double darker line. This species flies in May and +June, and though apparently widely distributed, can hardly be described +as common. + +The caterpillar feeds on the white willow (_Salix alba_) and sallow (_S. +caprea_) in August and September; and the chrysalis may be found in a +silken cocoon among the fallen leaves throughout the winter. + + +_The Blue-bordered Carpet_ (_Melanthia bicolorata_) + +This same family (_Larentiidae_) is remarkable for its large number of +pretty moths, popularly known as the 'Carpets,' many of which are +exceedingly common in our woods and gardens. + +[Illustration: FIG. 201.--THE BLUE-BORDERED CARPET.] + +Our first example of these is the Blue-bordered, which is pretty well +represented in several counties of Great Britain and Ireland. Its white +fore wings are boldly marked with a blotch of greyish brown at the base, +and another extending from the middle of the costal margin more than +halfway across. The hind margin is marked with two bluish grey bars, +separated by a white line. The hind wings are white, with a very small +dark spot, and a bluish grey margin something like that of the fore +wings. + +The caterpillar is green, with longitudinal stripes of a darker and +lighter shade. It feeds in June on the alder (_Alnus glutinosa_) and +blackthorn (_Prunus spinosa_); and when full grown it changes to a brown +chrysalis within a light silken web. + +The moth flies in July and August. + + +_The Beautiful Carpet_ (_Melanthia albicillata_) + +The Beautiful Carpet belongs to the same genus as _Bicolorata_. Its +wings are of a rich creamy white, clouded with grey along the hind +margin. The basal blotches of the fore wings are large, of a dark brown +colour, and marbled with a light tint. Near the tips of these wings is +another conspicuous blotch of the same colour, from which a delicate +wavy dark line runs to the inner margin. A small dark spot also lies +near the middle of the costal margin of each of the four wings. + +[Illustration: FIG. 202.--THE BEAUTIFUL CARPET.] + +The caterpillar is green, with a white line along the spiracles, and a +triangular reddish spot on the back of segments four to ten inclusive. +It feeds on the bramble (_Rubus fruticosus_), raspberry (_R. Idaeus_), +and wild strawberry (_Fragaria vesca_). It may be found in June and +July. + +The moth flies in June. + + +_The Common Carpet_ (_Melanippe sociata_) + +The genus _Melanippe_ contains twelve species, some of which are +extremely common. One of these moths--the Common Carpet--is represented +in fig. 203. Its wings are all of a smoky-brown colour, crossed by +numerous white lines, the arrangement of which may be gathered from our +illustration better than from a written description. It is a +double-brooded insect, appearing first in May, and then again about the +end of July. + +[Illustration: FIG. 203.--THE COMMON CARPET.] + +The caterpillar is mottled with shades of brown and grey. On the back +are five or six greyish-white lozenge-shaped marks, and there are a few +white dots on the back of each segment. It feeds on the hedge bedstraw +(_Galium Mollugo_), and when full grown it changes to a chrysalis in a +light cocoon on the ground. + + +_The Silver Ground Carpet_ (_Melanippe montanata_) + +In this species the ground colour is silvery white. The bases of the +fore wings are blotched with pale brown, and a dark brownish-grey bar, +containing a black spot, crosses the middle. The hind margins of the +fore wings are faintly marked with pale brown, and lines of the same +tint, more or less distinct, cross the hind wings. + +[Illustration: FIG. 204.--THE SILVER GROUND CARPET.] + +This moth is very common in all parts of the country, and may be seen on +the wing throughout the summer. + +The caterpillar is light brown, with several longitudinal lines of +different colours. On the back of each of the segments seven, eight, and +nine is a distinct black V-shaped mark, terminating behind with a bright +red spot. It feeds on the primrose (_Primula acaulis_) in the autumn, +hybernates through the winter, and is full grown about the beginning of +April. + + +_The Garden Carpet_ (_Melanippe fluctuata_) + +Our third and last member of this genus is the Garden Carpet--a moth +that must be pretty well known to almost everybody, since it is the +commonest of all the _Geometrae_ that frequent our gardens. + +[Illustration: FIG. 205.--THE GARDEN CARPET.] + +The fore wings are pale grey or brownish, with a patch of dark greyish +brown at the base, another larger one on the middle of the costa, and a +third near the tip. The wing is usually clouded between the middle +blotch and the inner margin, and numerous fine wavy lines, more or less +distinct, cross the wing. + +This moth may be seen throughout the summer, from May to September, but +is most abundant in June and July. + +The caterpillar is extremely variable in colour, being either green, +brown, or grey, or some intermediate tint; and is marbled and dotted +with dark brown on the back. It feeds on the nasturtium (_Tropaeolum +majus_), rape (_Brassica Napus_), and various other cruciferous plants; +and may be found from April to August. + + +_The Yellow Shell_ (_Camptogramma bilineata_) + +Passing over two smaller genera, we come to the beautiful little Yellow +Shell. This moth is so abundant in most parts that we arouse it at +almost every stroke while beating low bushes. + +All its wings are yellow, and crossed by numerous delicate white and +brown lines. The most conspicuous feature is the two white lines, with +dark brown edging, crossing the fore wings. + +[Illustration: FIG. 206.--THE YELLOW SHELL.] + +The caterpillar feeds by night, and is therefore seldom seen except by +those who make special nocturnal searches with the aid of a lantern or +sweep net. It devours various grasses, and hides itself among the roots +or under stones during the daytime. It is full grown in April or May. +The colour is dull pale green, with a dark green dorsal line, and two +white stripes on each side. + + +_The Small Ph[oe]nix_ (_Cidaria silaceata_) + +Again passing over a few small and less important genera, we select the +small Ph[oe]nix as the last example of this very extensive family. + +[Illustration: FIG. 207.--THE SMALL PH[OE]NIX.] + +The fore wings of this species are dark brown, paler toward the hind +margin. Most of the wing rays are generally of a pale yellowish colour, +and a variable and complicated system of whitish lines crosses the wings +near the base, and another near the hind margin. Among the latter there +is always a series of dark triangular spots, with apices pointing +towards the hind margin. + +This moth is moderately common throughout the British Isles, and is +double brooded, appearing in May and August. + +The caterpillar is green, with a row of brown spots along the middle of +the back. When full grown it changes to a chrysalis in a light web. + + +Family--EUBOLIIDAE + +This is the last family of the _Geometrae_ we shall notice, and contains +ten species. Most of these are rather pretty moths, and all have the +tips of the fore wings more or less pointed. As a rule, too, there is a +dark streak running from the very tip of the wing for a short distance +obliquely inward. + +They are generally very light sleepers, and are easily beaten from their +hiding places during the day. + +The larvae are not humped, and may be found feeding on low plants. + +We shall briefly examine two species. + + +_The Small Mallow_ (_Eubolia limitata_) + +This moth is pretty abundant in waste places from June to August, and is +easily obtained by lightly beating the foliage of small bushes and low +plants. + +[Illustration: FIG. 208.--THE SMALL MALLOW.] + +Its fore wings are pale brown crossed by a broad central bar, the edges +of which are darker. The hind wings are of a paler brown, and are +crossed by two or three fine wavy lines. + +Although the perfect insect is so common, the caterpillar seems to be +seldom met with. It is a grass feeder, and may be looked for in May and +June. + + +_The Treble Bar_ (_Anaitis plagiata_) + +Our last example of the _Geometrae_ is the Treble Bar, a very pretty +moth, which is illustrated in fig. 9 of Plate XII. It may be readily +identified by the aid of this coloured picture, and therefore need not +be described in words. It is pretty generally distributed throughout the +British Isles, and is in some parts a very abundant species, +particularly so in the neighbourhood of London. + +The caterpillar is brown, with paler spaces between the segments. The +dorsal line is black and interrupted, and a yellow line runs along each +side. It feeds on the leaves and flowers of the perforated St. John's +wort (_Hypericum perforatum_). + +This insect is double brooded, the moth appearing in May and August, and +remaining with us throughout the month following in each case. + + + + +CHAPTER XXI + +_THE MICRO-LEPIDOPTERA_ + + +The butterflies, and all the moths contained in the groups of the last +four chapters, are commonly spoken of as constituting the +_Macro-lepidoptera_; but in addition to these there are many hundreds of +small British moths that represent what is known as the +_Micro-lepidoptera_. + +It is not usual for young entomologists to have much to do with the +'Micros' until they have had a little practical experience with the +larger species; in fact, a good number of them never seem to extend +their knowledge beyond the limits of the 'Macros' except that they may +make an occasional capture of a Micro that happens to fly across their +path. + +Now, since it would be practically impossible to deal fairly, even in +outline, with both these divisions of the _Lepidoptera_ in a work of the +present dimensions, I have devoted most space to the larger species so +as to meet the probable requirements of the majority of my readers. But +in order that the beginner may also have the means of introducing +himself intelligently to a study of the 'Micros,' I shall set apart this +chapter for a simple account of the broad principles of their +classification, illustrated by means of a few types, so that the +collector may at least know _something_ of the insects he captures, even +though he may not be able at once to fix on their names. + +The young entomologist, thus provided with the broad features that +enable him to roughly classify the specimens which reach his cabinet, +may, as his store increases, pay an occasional visit to a public museum +or the private collection of an entomological friend, and so obtain the +names and other details he may require. + +The _Micro-lepidoptera_ are divided into five main groups--_Pyralides_, +_Pterophori_, _Crambi_, _Tortrices_, and _Tineae_, each of which is +divided into families and genera, as we have seen in the case of the +'Macros.' + + +_Pyralides_ + +The _Pyralides_ may be easily distinguished by the proportionately long +fore wings, long legs, and elongated abdomen. Some of them have wings of +a pearly lustre, and are accordingly known popularly as the 'Pearls.' +Some species fly in bright sunshine, others appear on the wing before +sunset, and fly till dusk; others, again, are purely nocturnal in their +habits. All, however, are apparently light sleepers, and may be easily +beaten out of their resting places and netted by day. Some of these +moths are common everywhere, but the majority of them are very local, +though they may be extremely abundant where they occur. + +The larvae have a glossy and bristly appearance, and are generally +gregarious in their habits. + +This group contains about eighty species, arranged in five families as +follows: + + 1. _Pyralididae_, including about forty species. + 2. _Botydae_, about thirty species. + 3. _Steniiadae_, containing only five species. + 4. _Hydrocampidae_, four species. + 5. _Acentropodidae_, containing only one. + + +_The Tabby_ (_Aglossa pinguinalis_) + +The first of these families contains the Tabby or Grease Moth, commonly +met with both in the larval and perfect states in barns and stables. + +[Illustration: FIG. 209.--THE TABBY OR GREASE MOTH.] + +Its fore wings are brownish grey, crossed with zigzag darker lines, and +having a black spot near the centre of the costal margin. The term +'Tabby' has been applied on account of the fancied resemblance of the +transverse markings to the fur of a tabby cat, and the other popular +name was given under the belief that the caterpillar feeds on fatty +matter, but it is extremely doubtful whether this supposition is +correct. + +The caterpillar probably feeds exclusively on the vegetable +accumulations that lie in the undisturbed corners and crevices of +outhouses and stables, and lives concealed in silken tubes, strengthened +outside by fragments of hay, chaff &c. that have been spun together. It +feeds from September to April, except during very severe weather, and +when full grown it leaves its tube, and changes to a chrysalis in a +light silken cocoon in some secluded corner. + +The moth emerges in July. + + +_The Meal Moth_ (_Pyralis farinalis_) + +The same family contains the common Meal Moth, so called because in the +larval state it feeds on meal and allied substances. + +[Illustration: FIG. 210.--THE MEAL MOTH.] + +The fore wings are yellowish grey, with reddish basal patches, a broad +reddish band along the hind margin, and two whitish indented transverse +lines. The hind wings are grey, and are crossed by two lines similar to +and continuous with those of the front pair. + +This moth is to be found in abundance throughout the summer months in +places where corn, meal, and grain are stored in large quantities, +sitting on walls and rafters during the daytime, and taking to flight in +the evening. + +The caterpillar feeds on corn, meal, grain, bran, &c., and lives +concealed in a silken tube covered outside with particles of its food +substance. It is not fully grown till nearly two years old, and then +changes to a chrysalis in a white silken cocoon. + + +_The Small Magpie_ (_Eurrhypara urticata_) + +The family _Botydae_ contains the moths that are popularly known as the +'Pearls' on account of the pearly lustre of the wings. One of its +species--the Small Magpie--is shown in the accompanying illustration. +Its fore wings are pearly white, with blackish hind margin, a yellow +streak at the base, and blackish markings, the arrangement of which may +be seen in the figure. + +[Illustration: FIG. 211.--THE SMALL MAGPIE.] + +It is a very common moth, flying at dusk during June and July in waste +places where the stinging nettle grows. + +The caterpillar is whitish, with a dark dorsal line. It feeds on the +stinging nettle (_Urtica dioica_), always remaining concealed between +leaves which it has spun together with silken threads. + + +_The Mother-of-Pearl_ (_Botys ruralis_) + +This is another very common species of the family _Botydae_, abundant +almost everywhere, and to be found on the wing from June to August. + +Its wings are whitish, and exhibit a very decided pearly lustre, and all +the markings are of a dull dark grey. + +[Illustration: FIG. 212.--THE MOTHER-OF-PEARL.] + +The caterpillar is glossy, and has a semi-transparent appearance. It is +greenish white above, with a darker line down the back; and the sides +are of a brighter green. It feeds on the stinging nettle (_Urtica +dioica_) during May. + + +_The Garden Pebble_ (_Pionea forficalis_) + +The same family contains also the Garden Pebble, which is one of the +commonest frequenters of gardens, both in town and country. + +The fore wings are pale yellowish grey with brown markings. The latter +include a fine line from the tip to the middle of the inner margin, and +another paler one inside and parallel with this, having a dark spot near +its centre. The hind wings are lighter, and have a pale and interrupted +line parallel with the hind margin. + +[Illustration: FIG. 213.--THE GARDEN PEBBLE.] + +The caterpillar is pale greenish, with a dark line along the back and on +each side. It feeds on the cabbage and other cruciferous plants. + +The moth flies from May to the end of the summer, and the caterpillar +may be found about midsummer, and again in the autumn. + + +_The Beautiful China Mark_ (_Hydrocampa stagnata_) + +Our last example of the _Pyralides_--the Beautiful China Mark--belongs +to the family _Hydrocampidae_. This small family is remarkable for the +fact that its four species spend their larval state in the water, +feeding on the under surfaces of the leaves of water lilies and other +aquatic plants. These curious larvae live either in cases which they +construct for their protection, something after the fashion of the larvae +of caddis flies, or quite free in the water, and then they are supplied +with special breathing organs that enable them to absorb the oxygen held +in solution in the water. + +[Illustration: FIG. 214.--THE BEAUTIFUL CHINA MARK.] + +The moth we have selected for illustration is a very common species, and +may be seen flying in great numbers in the neighbourhood of ponds during +June and July. + + +_The Pterophori_ + +The members of this remarkable group are easily distinguishable from all +other moths by the feathery appearance of their wings, a feature that +has gained for them the popular name of _Plume Moths_. Their fore wings +are more or less divided or cleft, and their hind wings are generally +divided into three distinct feathery plumes. + +The larvae are hairy, and when full fed they suspend themselves by their +anal claspers, and change to the chrysalis state without any kind of +covering. They are generally to be found in spring and early summer, but +some of them feed in the autumn. + +The chrysalides are often hairy, though some of them are perfectly +smooth. + +Plume moths are to be met with more or less throughout the year. Many of +the earlier species appear on the wing in spring and early summer; but +the late feeders emerge in the autumn, and hybernate through the winter, +often taking to the wing on the mild days of our coldest months. + +The _Pterophori_ include only about forty British species, all of which, +with two exceptions, belong to the family _Pterophoridae_. The two +exceptions represent as many families--one the _Chrysocorididae_, and the +other the _Alucitidae_. + + +_Platyptilia gonodactyla_ + +This is one of the commonest of the _Pterophoridae_, generally appearing +in our gardens and in waste places towards the end of May, and +continuing with us for some time. It starts from its retreat at or +before sunset, and remains on the wing after dark. + +[Illustration: FIG. 215.--GONODACTYLA.] + +Its fore wings are ochreous grey, with a narrow brown costal margin, and +a triangular brown patch on the costa. Beyond this patch the wing is +cleft. The hind wings consist of three distinct brownish plumes, the +third of which has a small tuft of black scales projecting from the +middle of the inner margin. + +The caterpillar feeds on the flower stalks of the coltsfoot during March +and April. + + +_Leioptilus osteodactylus_ + +This is another species of the same family. It is not uncommon, but is +more local than the last. + +[Illustration: FIG. 216.--OSTEODACTYLUS.] + +Its fore wings are pale yellow, with a small brown dot at the +commencement of the dividing fissure, and a brown blotch on the costal +margin nearer the tip. The hind wings are divided into three distinct +plumes like those of _Gonodactyla_. + +This is a later species, appearing on the wing in July. + + +_Aciptilia pentadactyla_ + +The fore wings of this species are white, frequently with a few greyish +scales, and are deeply divided into two feathery plumes. The hind wings +are pure white, and consist of three plumes. + +[Illustration: FIG. 217.--PENTADACTYLA.] + +This pretty insect is common and widely distributed, and flies during +June and July. + +The caterpillar feeds on the convolvulus in May. + + +_Alucita hexadactyla_ + +Our last example of the _Pterophori_ is the Twelve-plume Moth, the only +British representative of the family _Alucitidae_. + +This little insect is of a yellowish colour, with two dark bands across +the fore wings; and both fore and hind wings are divided into six +distinct feathers. It is a common moth, and frequents sheltered spots, +flying at dusk. It appears in August, remains on the wing till October, +and then hybernates till the following April. During the winter it is +commonly met with in outhouses and even in dwelling houses. + +[Illustration: FIG. 218.--HEXADACTYLA--ENLARGED.] + +The caterpillar feeds during June and July on the flower buds of the +honeysuckle (_Lonicera Periclymenum_). It is not hairy, like most of the +larvae of the last family; and, unlike these, it changes to a chrysalis +in a silken cocoon. + + +_Crambi_ + +The third group of the 'Micros' is the _Crambi_, and contains about +eighty species, arranged in four families. + +Some of them are common moths with which all must be more or less +familiar, as they are roused from the grasses on which they repose at +almost every footstep as we walk through meadows in the summer. When at +rest, they present a very peculiar appearance. Their wings are wrapped +closely round their bodies in such a manner that they are hardly +distinguishable from the stems on which they repose. + +The larvae have sixteen limbs, and are very variable in their habits. +Some feed among moss or dry stems in silken tubes, some on the stems of +reeds, and others inhabit the hives of bees and feed on the wax of the +honeycomb. + +The four families are: + +1. _Chilidae_--five species. + +2. _Crambidae_--about thirty species. + +3. _Phycidae_--over forty species. + +4. _Galleridae_--five species. + + +_Chilo Phragmitellus_ + +This species is one of those moths known as the 'Veneers,' and is +popularly termed the Wainscot Veneer. It is one of the largest of the +family _Chilidae_. + +Its fore wings are long, narrow, and pointed at the tip. They are of a +pale ochreous brown colour, with a row of small black dots along the +hind margin. + +The caterpillar is pale grey, with brown stripes; and the head and +second segment are yellowish brown. It feeds on the common reed +(_Phragmites_) in the autumn, and hybernates till the following spring, +when it resumes its feeding. + +[Illustration: FIG. 219.--PHRAGMITELLUS--ENLARGED ONE-HALF.] + +This insect is rather local, but may be searched for in all marshy +places where reeds abound. + + +_Crambus hamellus_ + +The family _Crambidae_ is represented by the above-named species, which +has the popular title of Pearl-streak Veneer. It is not a common moth, +but is to be obtained in some localities by beating low herbage. + +[Illustration: FIG. 220.--HAMELLUS--SLIGHTLY ENLARGED.] + +Its fore wings are ochreous and glossy, with a silvery streak from the +base, running almost parallel with the costal margin. The hind margin is +yellow, bordered inside by a wavy brown line. The hind wings are pale +greyish brown with a yellowish margin. + + +_Crambus tristellus_ + +The same family contains the species _Tristellus_, which, unlike the +preceding insect, is abundant everywhere. + +[Illustration: FIG. 221.--TRISTELLUS.] + +Its fore wings are generally yellowish brown, but exceedingly variable. +A pale streak runs from the base to just beyond the middle of the wing, +and is then forked. Near the hind margin is a very indistinct brown wavy +line. The hind wings are dull smoke colour with a light fringe. As with +the other moths of the family, its labial palpi are very long. + +The moth flies from July to September. + + +_Crambus hortuellus_ + +This is also an abundant species, to be met with everywhere during June +and July. + +Its fore wings are dull ochreous brown. The wing rays are whitish near +the inner margin, and a brown line with a silvery edging crosses near +the hind margin. The hind wings are dull smoky brown, with a shining +surface, and the fringe is light. + +[Illustration: FIG. 222.--HORTUELLUS.] + +The larva is pale grey with dark grey spots, and may be found among moss +in April and May. + + +_Galleria mellonella_ + +Our last example of the _Crambi_ is a moth that the young entomologist +is not likely to meet with unless he happens to be in the neighbourhood +of one of its haunts, but its habits are so peculiar that we are tempted +to introduce it on that account. + +[Illustration: FIG. 223.--MELLONELLA.] + +It belongs to the family _Galleridae_, the larvae of which feed on the wax +combs in the hives of bees and in the nests of wild bees. They are +protected from the stings of the inmates by silken tubes which they +construct, and by the hardened covering of their heads and front +segments--the only parts that remain exposed while they are feeding. + +The fore wings of the moth are reddish-grey or brownish, sometimes with +a greenish tinge, and yellowish along the inner margin. The hind wings +are greyish brown. + +It flies in July and August, and the caterpillar feeds in May and June. + + +_The Tortrices_ + +This is a large group of moths, deriving their name from the peculiar +habit of a number of the larvae of twisting or rolling up leaves for +their protection. This habit, however, is not common to all, for some +feed on stems and flowers, and others devour seeds and fruits. + +The perfect insects may easily be known by the shape of the wings. The +fore pair are gracefully curved on the costal margin in such a way that, +when the insect is at rest with its wings closed, its outline is much +the shape of a bell. + +The identification of the various species of this extensive group is no +easy task, for many of them are so variable in their colouring that +insects of the same species are often very different from each other. +So puzzling indeed is this tendency to run into varieties that many +insects, once considered to belong to separate species, have been +reduced to one; and this has been the case in a number of instances. + +There are so many of these little moths that we cannot even give a +representative of each family, but the following outline will serve to +show the extensiveness of the group. + + Family 1. _Tortricidae_, about sixty species. + " 2. _Penthinidae_, " twenty " + " 3. _Spilonotidae_, " twelve " + " 4. _Sericoridae_, " twenty-seven species. + " 5. _Sciaphilidae_, " twenty-four " + " 6. _Grapholithidae_, about one hundred and fifty species. + " 7. _Pyraloididae_, four species. + " 8. _Conchylidae_, about fifty species. + " 9. _Apheliidae_, three species. + +We shall now briefly examine a few of the commonest insects of the +group. + + +_Tortrix xylosteana_ + +This pretty moth is common in most parts, and may often be met with in +abundance in wooded localities during July. It belongs to the family +_Tortricidae_. + +Its fore wings are ochreous brown. A very dark oblique streak, edged +with yellow, runs from the inner margin of the base. A reddish patch in +the centre of the wing, also edged with yellow, is narrow on the costa, +and expands as it approaches the inner margin. Beyond this are another +dark patch on the costa and two reddish-brown blotches on the hind +margin. + +[Illustration: FIG. 224.--XYLOSTEANA WITH WINGS CLOSED.] + +The larva is greenish brown, marked with white spots which have black +centres; and it feeds on oak (_Quercus Robur_), honeysuckle (_Lonicera +Periclymenum_), and other plants, in the month of May. + + +_Tortrix viridana_ + +In June and July this pretty but destructive little insect may be seen +flying in abundance in almost every oak wood. Its fore wings are one +uniform pale green with the exception of a streak of yellow along the +costal margin; and, when at rest, scores may exist on a single twig +without being seen unless closely examined. The hind wings are of a pale +smoky tint, and rather glossy. + +The larva is green, with black spots, and feeds in May and June on the +oak and other trees, often almost completely devouring the foliage. + +[Illustration: FIG. 225.--VIRIDANA.] + + +_Peronea cristana_ + +This moth is not so generally abundant, but is very common in many of +the woods of the south. It is remarkable for the large number of +varieties that have been observed, many of which have been regarded as +distinct species. + +[Illustration: FIG. 226.--CRISTANA--ENLARGED.] + +Its fore wings are of some shade of brown or grey, with a light streak +of variable colour along the inner margin, and a tuft of raised white +scales in the middle of the wing. + +It flies during August and September. + + +_Ptycholoma lecheana_ + +Our last example of the family _Tortricidae_ is _Lecheana_, a moth that +is common in most parts in June and July. + +[Illustration: FIG. 227.--LECHEANA.] + +Its fore wings are brown, lighter towards the base. There are no very +distinct markings, but there is generally a darker patch in the middle +of the wing, edged with a silvery streak on each side. + +The larva feeds on several trees, including oaks and elms, in the month +of May. + + +_Penthina pruniana_ + +[Illustration: FIG. 228.--PRUNIANA.] + +The next family--_Penthinidae_--contains the common species _Pruniana_, +which may be readily known by its boldly marked wings. The basal portion +of the fore wings, to the extent of nearly two-thirds of the whole, is +very dark brown. The remaining third is almost white, and clouded with +grey. The hind wings are smoky brown with a paler fringe. + +The caterpillar of this species feeds on the blackthorn (_Prunus +spinosa_) in May, and the moth flies in June and July. + + +_Antithesia salicella_ + +This moth is not nearly so common as the last species, but is fairly +plentiful in some localities in the south of England. It belongs to the +same family as _Pruniana_. + +[Illustration: FIG. 229.--SALICELLA.] + +The fore wings are whitish at the base and along the inner margin, but +the light tint is dotted and clouded with shades of brown. The remainder +of the wings is marbled with dark brown of different depths, relieved +near the hind margin with a little blue. The hind wings, as is usual +with the _Tortrices_, are dull smoky brown. + +The caterpillar is reddish brown with black spots, and feeds during May +in rolled leaves of willows. + +The moth flies in August and September. + + +_Sciaphila octomaculana_ + +Our single example of the family _Sciaphilidae_ is the species +_Octomaculana_, which, though not very abundant, is widely distributed, +and moderately common in parts. + +Its fore wings are white, dusted with grey, and each is marked with four +dark grey patches which have given rise to its specific name--a word +which signifies 'eight-spotted.' The hind wings are grey. + +[Illustration: FIG. 230.--OCTOMACULANA--ENLARGED.] + +The caterpillar feeds on thistles and other plants, and the moth flies +from August to October. + + +_Ephippiphora cirsiana_ + +This insect represents the family _Grapholithidae_. It is a common moth, +and is widely distributed. + +Its fore wings are greyish brown, with a large white patch on the middle +of the inner margin; and beyond this white, in the anal angle, is a +pale grey patch containing three or four black dots. The tips of the +wings are reddish brown. + +The moth flies in June and July; and the larva, which feeds on thistles, +may be found in the stems from October to the following May. + +[Illustration: FIG. 231.--CIRSIANA--ENLARGED.] + + +_Carpocapsa pomonella_ + +The same extensive family contains a few moths that are very destructive +to our fruits, the larvae burrowing into and living entirely within their +substance. One of these--_Pomonella_--is popularly known as the Codlin, +as its larva is so often found in the interior of small apples of the +same name. + +[Illustration: FIG. 232.--POMONELLA.] + +The fore wings of this insect are grey, with a number of dark transverse +lines. The spot in the anal angle is edged with a coppery tint, and +inclosed by a curved black line. + +This moth is common in all parts, flying during June and July; and the +larva may be looked for in apples and pears in August and September. + + +_Xanthosetia zoegana_ + +Our last example of the _Tortrices_ is _Zoegana_, which belongs to the +family _Conchylidae_. Its fore wings are yellow, with a reddish streak +along the costa near the base, and a small reddish spot opposite this +near the inner margin. The tip of the wings is dark reddish brown, in +the middle of which is a large yellow spot. + +[Illustration: FIG. 233.--ZOEGANA--ENLARGED.] + +This moth is widely distributed, and in some parts common. It flies from +May to August, and the larva feeds on the small scabious (_Scabiosa +columbaria_). + + +_The Tineae_ + +We have noticed that the _Tortrices_ form a very extensive group of +moths, but they are far outnumbered by the _Tineae_, for of these there +are over seven hundred known British species. + +Of course, among so many species we are sure to find considerable +variety in form and structure; but notwithstanding this, the _Tineae_ +form a well-marked division, and the beginner will find but little +difficulty in distinguishing between these and the other Micros. + +The wings are long and narrow, and are remarkable for the length of the +fringe, particularly that of the hind wings. The bodies, too, are long +and slender. + +The larvae are exceedingly variable. Some have the usual number of +sixteen limbs, and others have as many as eighteen. Again, the larvae of +several genera have only fourteen legs, and some are absolutely legless. + +With regard to their food and habits, they are equally variable, for +while some feed exposed, others are always protected in rolled leaves. +Some construct for themselves portable tubes, so that they always remain +under cover, and are at the same time perfectly free to ramble in search +for food. Some, also, are leaf miners; and the group includes the +so-called 'Clothes Moths,' whose larvae devour our garments, furs, and +the upholstering of our furniture. + +We shall now briefly notice a few species, in order that we may become +better acquainted with the general characters of the group. + + +_Diurnea fagella_ + +This moth represents the small family _Epigraphiidae_, containing only +six species, all of which appear in the winter or early spring. + +The present species is very common in most parts, and may be seen at +rest on the barks of trees in March and April. + +[Illustration: FIG. 234.--FAGELLA.] + +The fore wings are usually pale grey or yellowish grey, and dotted with +brown; but there is a great variety both in the depth of the ground +colour and the distinctness of the markings. Our illustration gives the +usual appearance of the insect. + +The caterpillar feeds on various trees in September and October, always +protected between leaves that it has spun together. + + +_Adela cuprella_ + +The family _Adelidae_ contains ten species, all remarkable for the great +length of their antennae. The one selected for illustration is a +beautiful little moth with bright bronzy green fore wings, tinged with a +rich glossy violet. The hind wings are brown with a glossy surface. + +[Illustration: FIG. 235.--CUPRELLA.] + +This moth does not seem to be widely distributed, but is fairly +plentiful where it occurs. Wimbledon Common and Epping Forest are good +localities for it. It is on the wing in April and May. + + +_Hyponomeuta Padellus_ + +The family _Hyponomeutidae_ contains about twenty insects, some of which +are very common and exceedingly destructive to our trees. In May and +June hawthorn and fruit trees may be seen swarming with the gregarious +larvae of some of them, and almost entirely stripped of their leaves. + +[Illustration: FIG. 236.--PADELLUS.] + +The species here figured has grey or white fore wings with three rows of +black dots. The hind wings are darker grey without dots. + +The larva feeds on hawthorn, apple, and other trees. The perfect insect +flies in July and August. + + +_Depressaria nervosa_ + +The next family--_Gelechiidae_--is represented by the species Nervosa, +which is common in many localities. + +[Illustration: FIG. 237.--NERVOSA--TWICE NATURAL SIZE.] + +Its fore wings are reddish brown, and are marked by a number of short +longitudinal streaks of a darker colour. The hind wings are light grey. + +The caterpillar is black, marked with black spots in white rings, and +having yellow side stripes. It feeds on the flowers of the hemlock +water dropwort (_[OE]nanthe crocata_) during June and July. + +The moth flies in August and September. + + +_Harpella Geoffrella_ + +The same extensive family contains the moth Geoffrella, represented in +the accompanying cut. This is an exceedingly pretty insect. The basal +portion of its fore wings is yellow, with two longitudinal dark streaks, +the outer one of which is bent towards the inner margin near the middle +of the wing. The remaining portion of the wings is brown, with two +yellowish triangular spots, one on the costal and one on the inner +margin. On the middle of the costa is a short dark streak. + +[Illustration: FIG. 238.--GEOFFRELLA.] + +This moth appears in May and June, and is rather local, but very +abundant in some parts. + + +_Coleophora ibipennella_ + +The family _Coleophoridae_ contains about seventy small moths, +characterised by their very narrow and pointed wings, with long fringes, +and also, generally, by a little tuft of hair on the first joint of the +antennae. + +[Illustration: FIG. 239.--IBIPENNELLA--ENLARGED.] + +The larvae live in little cases which they construct, and feed on various +leaves and seeds. They spend the winter within their cases, and change +to the chrysalis state in spring or early summer. + +One of these moths--_Ibipennella_--is shown in fig. 239. Its fore wings +are white, with a satiny gloss, and brownish towards the tips. The +'nervures' are generally of a yellowish tinge. The hind wings are dark +grey. + +The larva feeds on the birch (_Betula alba_), and may be seen walking on +the surface of the leaves, carrying, or rather dragging after it, the +pistol-shaped case in which it lives, nothing protruding save its head +and front legs. It is full fed in May, and the moth flies in July. + + +_Tischeria complanella_ + +This species represents the rather extensive family _Elachistidae_, the +members of which have narrow and pointed wings. Many of them are adorned +with beautiful metallic tints, but are generally so small that a lens is +necessary to show up the splendour of their clothing. Most of the larvae +are leaf miners, and are easily reared. All that is necessary is to +pluck a few twigs, the leaves of which, when held up to the light, +reveal the tiny larvae in their burrows, and place them in a vessel of +water. They do not feed long, and it is probable that most of the larvae +so treated will be ready to change before the leaves have become dry. +The present species has bright yellow fore wings, with pale grey +cloudings at the hind margins. It is very abundant in many parts, and +flies during the month of June. + +[Illustration: FIG. 240.--COMPLANELLA--ENLARGED.] + +The larva is one of the numerous leaf miners, and is of a yellowish +colour. It feeds in oak leaves during the autumn, and its presence is +indicated by light blotches on the foliage. + + +_Nepticula aurella_ + +The family _Nepticulidae_--the last of the _Tineae_--contains a number of +little moths, including the smallest of the _Lepidoptera_. Many of them +are exceedingly beautiful, being decorated with various tints of a +splendid metallic lustre, but their beauty is revealed only by the use +of a magnifying lens, and they are so small that very great care and +patience is required to set them properly. + +They may be recognised by their short and thick antennae, rather large +head, broad fore wings, and narrow pointed hind wings. + +The larvae have no true legs, but have nine pairs of very imperfectly +developed claspers. They are leaf miners, and are sometimes so abundant +that several may be found in a single leaf. + +[Illustration: FIG. 241.--AURELLA--ENLARGED.] + +The species we have selected has fore wings of a rich golden brown, with +deep violet tips, and a broad bar of pale golden yellow beyond the +middle. It may be found throughout the spring and summer. The larva +excavates long irregular burrows in the leaves of the bramble. + + + + +APPENDICES + + +APPENDIX I + +I have previously called the reader's attention to our classified list +of butterflies and moths, and have hinted at one or two of the objects +for which it is inserted. It contains the scientific and popular names +of all the British Butterflies, _Sphinges_, _Bombyces_, _Noctuae_, and +_Geometrae_, arranged in their various families and genera; and in cases +where two specific names are commonly applied to the same insect, both +are given. + +Its chief uses to the young entomologist are to show the relation which +the insects bear one to another, and to supply a guide for the proper +arrangement of the specimens in his cabinet. + +The order adopted is that of South's 'Synonymic List of British +Lepidoptera,' and it has already been mentioned that similar lists, +printed on one side of the paper only, may be obtained from dealers in +naturalists' appliances. These, cut up as required, supply very neat +labels for cabinets or store boxes. + + +_COMPLETE CLASSIFIED LIST OF BRITISH MACRO-LEPIDOPTERA_ + +=RHOPALOCERA (BUTTERFLIES).= + + PAPILIONIDAE. +

lepidopterist depends +greatly on his knowledge of the times at which the various butterflies +and moths generally appear, and of the localities which they are known +to frequent. The experiences he has gained in the past enable him to +calculate on the probabilities of the future, and he chooses both time +and locality according to his requirements. + +As he makes his way to the hunting ground he counts over the chances of +meeting with a certain insect that is wanted to fill a long-standing +blank in his cabinet; and we hear him discussing the probabilities as to +whether this species is yet 'out,' or whether the larvae of that species +are feeding. + +How different it is with the young and unguided entomologist! He rambles +promiscuously here and there, having only the faintest idea as to what +he is likely to see, and perhaps meeting with only four or five species +when an experienced collector, without covering a larger area of ground, +would take scores in the same time. + +In order to afford some little help to the beginner, I have thought it +advisable to introduce a calendar of operations to guide him in his +work. The space at our command would not allow this to be carried out in +detail, but the general instructions will undoubtedly assist most of my +readers until the practical experience gained by a few years' work has +enabled them to run on their own legs. + +Of course, in making reference to the monthly lists of insects on the +wing, allowance must be made for the forwardness or backwardness of the +seasons. Thus, an insect entered in the April list _may_ appear in March +in an exceptionally warm season, but may not emerge till the early part +of May if the spring has been unusually severe. + +It will be observed that in cases where all the species of a certain +genus or family appear on the wing in the same month, the name of that +genus or family is entered on the list instead of the names of the +individual species; but the latter can easily be obtained by reference +to Appendix I. + + +JANUARY + +There is not much field work to be done during this month. If the +weather is very severe, hardly an insect will be found on the wing; but +a mild January will sometimes entice the Brimstone Butterfly (_Rhamni_) +and some of the hybernating Vanessas from their winter quarters. + +Hybernating moths may also be met with, on the wing if the weather +is mild, or sleeping in their sheltered nooks during the frosts. +These include several _Noctuae_--_Auricoma_, _Lithargyria_, +_Suffusa_, _Vaccinii_, _Spadicea_, _Erythrocephala_, _Satellitia_, +_Rubiginea_, _Croceago_, _Vetusta_, _Exoleta_, _Ornithopus_, +_Furcifera_, _Semibrunnea_, _Socia_, and _Libatrix_; and also a few +_Geometrae_--_Zonaria_, _Fluviata_, _Dubitata_, _Siterata_, and _Miata_. + +In addition to these hybernating insects, the collector may examine tree +trunks and fences for the Early Moth (_Rupicapraria_), and late +specimens of the Winter Moth (_Brumata_); and towards the end of the +month he may expect to meet with fresh specimens of the Pale Brindled +Beauty (_Pedaria_) and the Spring Usher (_Leucophaearia_). A few of the +_Tineae_ may also be seen. + +The net need not be used at all during the colder months of the year, as +the moths are easily taken in pill boxes from the trunks and fences on +which they rest. + +Pupa digging may be carried on throughout the month if the weather is +sufficiently mild, but it is of no use attempting this during a frost. +Hybernating larvae may also be searched out of their winter quarters if +the collector does not mind giving them the attention they require; but, +as a rule, it is better to wait till they themselves start out to feed +in the spring, at which time all their food plants are showing leaf. + + +FEBRUARY + +Our remarks under 'January' concerning pupa digging and other work apply +equally well to this month. The same hybernating butterflies and moths +may be looked for; and, in addition to _Pedaria_, _Leucophaearia_, and +_Rupicapraria_, which now appear more plentifully, the following species +will probably be seen: + + Small Eggar (_Lanestris_) + Small Brindled Beauty (_Hispidaria_) + Oak Beauty (_Strataria_) + Dotted Border (_Marginaria_) + March Moth (_AEscularia_) + +About half a dozen species of the _Tineae_ will also have made their +appearance before the end of the month. + + +MARCH + +Many of the hybernating larvae will come out during March if the weather +is mild, and commence to feed; and the young caterpillars will begin to +appear from the eggs of the early moths already named. This is +consequently a good time to commence the search for larvae if you intend +to go in for rearing. During the daytime some may be beaten from the +boughs of trees and shrubs; and those which feed on low plants, being +generally nocturnal in their habits, should be searched for in the +evening, after dark, with the aid of a lantern. + +The hybernating butterflies are now flying more freely than before, and, +if the weather is bright and warm for the time of year, a few freshly +emerged species may be seen. These may possibly include: + + Large White (_Brassicae_) + Small White (_Rapae_) + Green-veined White (_Napi_) + Holly Blue (_Argiolus_) + +As regards moths, several fresh species may be expected to appear, while +those named as appearing in February are still to be found.

About twenty species of +the _Pyralides_, one or two of the _Pterophori_, a few _Crambi_, about +fifty of the _Tortrices_, and no less than two hundred of the _Tineae_. +The collector will do well to search fences and tree trunks for these +moths, whenever he has the opportunity; and also to use the net freely +in wooded country, waste places, and along hedgerows, _before_ and at +dusk. + + +JUNE + +There is a marked increase in winged insect life during this month. The +early butterflies are disappearing, or perhaps have quite left us; but +new species are taking their place. The _Sphinges_ now reach their +maximum, as do also the _Bombyces_; and the other groups are almost if +not quite up to their highest total. The _Noctuae_ and _Geometrae_ each +amount to over a hundred species. No less than a hundred and fifty +British _Tortrices_ are on the wing; the _Tineae_ make a near approach to +three hundred, and the _Pyralides_ of the month are not far short of +numbering a hundred species. It will thus be seen that the net and pill +boxes, as well as the setting boards, are in constant demand. + +Dull days may be well occupied in beating for moths, and in the +examination of fences and the bark of trees; and on bright days, as soon +as the butterflies have settled down to rest, the same work may be +carried on till dusk. + +Micros and _Geometrae_ are out early in the evening, when they should be +taken with the net. Later on the _Noctuae_ may be seen playing round +their favourite flowers. + +Sugar and light traps are likely to do good service during June, and +decoy females of the _Bombyces_ group may be called to your aid. + +Larvae are also abundant during June, and those of most of the +butterflies may be taken by carefully searching their food plants. + +The following is the list of imagines for the

+_Sphinges_ are beginning to fall off, and so are the _Bombyces_, but the +_Noctuae_ and _Geometrae_ are slightly on the increase. + +As regards the Micros, a good number of fresh species may be expected, +all the groups exhibiting a marked increase in the total number on the +wing with the exception of the _Tineae_. + +Sugaring is likely to pay well this month, and many moths may be

Light traps may also be used with much success during August. + +Fallen fruits should be examined for the larvae that feed within them; +and late in the month ripe fruit will supply food to the lovers of +sweets. + +Ivy blossom should be well worked at night; and clover and lucerne +fields form admirable hunting grounds for moths at night, especially +just after rain. + +Larvae are to be obtained

considerably lower, yet there +is a good deal to be done both with butterflies and moths. + +Many of the former are worn and ragged, but good fresh specimens of some +species may be taken. Clover and lucerne fields and the flowery borders +of corn fields remain very attractive. + +Tree trunks and palings should be searched as before. Sugar still +attracts numbers of the _Noctuae_; and ivy blossom should be examined at +night whenever an opportunity offers itself. + +September is a good month for larva hunting. Most of the species that +pupate in the autumn are now full fed, and will undergo the change to +the chrysalis state shortly after they have been housed, thus giving but +little trouble to the entomologist. The day feeders may be beaten or +swept from their food plants, but, of course, the nocturnal species are +best discovered by searching at night. + +Some have already 'gone down' for the winter, and, consequently, pupa +hunting may be started. However, as there is yet much to be done with +imagines and larvae, it may, perhaps, be better to leave the pupae alone +till about the end of the month, especially as many of the larvae have +not yet had time to complete their transformation. + +The list of imagines for September includes: + + =Butterflies.= + Clouded Yellow (_Edusa_) + Brimstone (_Rhamni_) + Queen of Spain (_Latona_) + Comma (_C-Album_) + Large Tortoiseshell (_Polychloros_) + Small Tortoiseshell (_Urticae_) + Peacock (_Io_) + Camberwell Beauty (_Antiopa_) + Red Admiral (_Atalanta_) + Painted Lady (_Cardui_) + Speckled Wood (_Egeria_) + Wall (_Megaera_) + Grayling (_Semele_) + Large Heath (_Tithonus_) + Small Heath (_Pamphilus_) + Small Copper (_Phl[oe]as_) + Common Blue (_Icarus_) + Clifden Blue (_Bellargus_) + Chalk-hill Blue (_Corydon_) + Holly Blue (_Argiolus_) + + =Sphinges.= + Death's-head Hawk (_Atropos_) + Convolvulus Hawk (_Convolvuli_) + Humming Bird Hawk (_Stellatarum_) + + =Bombyces.= + Tortrix (_Undulanus_) + Crimson Speckled (_Pulchella_) + Vapourer (_Antiqua_) + Pale Oak Eggar (_Crataegi_) + Lesser Lutestring (_Diluta_) + + =Noctuae.= + Figure of Eight (_Caeruleocephala_) + Small Wainscot (_Fulva_) + Bullrush (_Arundinis_) + Large Wainscot (_Lutosa_) + Frosted Orange (_Ochracea_) + Rosy Rustic (_Micacea_) + Feathered Brindle (_Australis_) + Beautiful Gothic (_Hispidus_) + Antler (_Graminis_) + Flounced Rustic (_Testacea_) + Hedge Rustic (_Cespitis_) + Haworth's Minor (_Haworthii_) + Anomalous (_Anomala_) + Shuttle-shaped Dart (_Puta_) + Dark Sword Grass (_Suffusa_) + Pearly Underwing (_Saucia_) + Turnip (_Segetum_) + Heart and Dart (_Exclamationis_) + Autumn Rustic (_Glareosa_) + Mouse (_Tragopogonis_) + Red-lined Quaker (_Lota_) + Yellow-lined Quaker (_Macilenta_) + Genus _Anchocelis_ + Genus _Xanthia_ + Centre-barred Sallow (_Xerampelina_) + Double Kidney (_Retusa_) + Genus _Polia_ + Black Rustic (_Nigra_) + Green-brindled Crescent (_Oxyacanthae_) + Marvel-du-jour (_Aprilina_) + Angle Shades (_Meticulosa_) + Flame Brocade (_Flammea_) + Brindled Green (_Protea_) + Genus _Calocampa_ + Genus _Xylina_ + Herald (_Libatrix_) + Gold Spot (_Festucae_) + Silver Y (_Gamma_) + Scarce Bordered Straw (_Armigera_) + Clifden Nonpareil (_Fraxini_) + Buttoned Snout (_Rostralis_) + + =Geometrae.= + Bordered Beauty (_Apiciaria_) + Brimstone (_Luteolata_) + Genus _Eugonia_ + November (_Dilutata_) + Autumnal (_Filigrammaria_) + Juniper Pug (_Sobrinata_) + Shaded Broad Bar (_Variata_) + Slender-striped Rufous (_Lapidata_) + Tissue (_Dubitata_) + Carpets (_Siderata_, _Miata_, _Immanata_) + Chevron (_Testata_) + Mallow (_Cervinata_) + Streak (_Spartiata_) + + +OCTOBER + +As there is very little winged life this month, and the larvae have +nearly all sought out their winter quarters, special attention may be +given to pupae. The earlier this work is started after the insects have +completed their change the better. If left late, many pupae will have +been destroyed by floods, moles, &c., and a prolonged series of frosty +days may render digging unproductive if not impossible. Again, it must +be remembered that some larvae are not yet down, and by digging at the +roots of the trees on which they are feeding, you are preparing an +acceptable bed for the late species, for the pupae of which you may call +again in about a month. + +Larvae may be obtained by beating and searching as before, but this work +should be done as early in the month as possible, since but few are +feeding after the first week or so. + +Butterfly catching is now practically over, only a few of the late +species and the hybernators being on the wing, and these only on mild +days. + +_Noctuae_ are still attracted by sugar and ivy blossom, and a few may be +found at rest. _Geometrae_ and Micros may be taken from palings and tree +trunks by day, or caught flying at dusk. + +The imagines of October may include the following butterflies: + + Brimstone (_Rhamni_) + Pale Clouded Yellow (_Hyale_) + Clouded Yellow (_Edusa_) + Comma (_C-Album_) + Large Tortoiseshell (_Polychloros_) + Small Tortoiseshell (_Urticae_) + Peacock (_Io_) + Camberwell Beauty (_Antiopa_) + Red Admiral (_Atalanta_) + Painted Lady (_Cardui_) + Small Copper (_Phl[oe]as_) + +And a few late 'Blues.' + +The principal moths of the month are: + + =Sphinges.= + Death's-head Hawk (_Atropos_) + + =Bombyces.= + Plumed Prominent (_Plumigera_) + + =Noctuae.= + Large Wainscot (_Lutosa_) + Red-lined Quaker (_Lota_) + Yellow-lined Quaker (_Macilenta_) + Beaded Chestnut (_Pistacina_) + Brown-spot Pinion (_Litura_) + Chestnut (_Vaccinii_) + Dark Chestnut (_Spadicea_) + Red-headed Chestnut (_Erythrocephala_) + Satellite (_Satellitia_) + Dotted Chestnut (_Rubiginea_) + Orange Upperwing (_Croceago_) + Brick (_Circellaris_) + Brindled Ochre (_Templi_) + Green Brindled Crescent (_Oxyacanthae_) + Marvel-du-jour (_Aprilina_) + Angle Shades (_Meticulosa_) + Flame Brocade (_Flammea_) + Red Sword-grass (_Vetusta_) + Sword-grass (_Exolita_) + Genus _Xylina_ + Sprawler (_Sphinx_) + Silver Y (_Gamma_) + + =Geometrae.= + Feathered Thorn (_Pennaria_) + Vestal (_Sacraria_) + Scarce Umber (_Aurantiaria_) + Mottled Umber (_Defoliaria_) + Winter (_Brumata_) + Northern Winter (_Boreata_) + November (_Dilutata_) + Juniper Carpet (_Juniperata_) + Gem (_Fluviata_) + Carpets (_Siderata_, _Miata_) + Mallow (_Cervinata_) + Streak (_Spartiata_) + + +NOVEMBER + +No butterflies are to be seen this month with the exception of the +hybernating species, and even these will not venture on the wing unless +the weather is mild and bright for the season. + +Most of the moths met with are also hybernators, but a few species are +to be found only at this season, and these should be looked for on +fences and tree trunks. A few _Noctuae_ may be taken at sugar, and the +_Geometrae_ attracted by lights. + +The only larvae now existing are hybernators, and many of these may be +met with during your pupa-digging operations; but they are best left +alone till the spring, as a rule. + +The chief work of the entomologist in November is certainly pupa +hunting, and this may be carried on in real earnest whenever the weather +is favourable, following the instructions given in Chapter VII. + +It will be remembered, also, that many of the _Lepidoptera_ pass the +winter in the egg state, and search may be made for ova when time +permits. + +The November list, besides some of the hybernating species previously +mentioned, include: + + =Bombyces.= + December (_Populi_) + + =Noctuae.= + Genus _Cerastis_ + Satellite (_Satellitia_) + Dotted Chestnut (_Rubiginea_) + Orange Upperwing (_Croceago_) + Brindled Ochre (_Exempli_) + + =Geometrae.= + Feathered Thorn (_Pennaria_) + Scarce Umber (_Aurantiaria_) + Mottled Umber (_Defoliaria_) + Winter (_Brumata_) + Northern Winter (_Boreata_) + + +DECEMBER + +Outdoor work is now at a minimum. The weather is too severe, as a rule, +to allow pupa digging to be carried on with either success or comfort, +but favourable opportunities should be seized for this employment as +well as for ova collecting. + +Now and again we may meet with _P. Populi_ at rest by day, or fluttering +round a light at night. _Brumata_ and _Defoliaria_ may also be seen, and +the Early Moth (_Rupicapraria_) may appear on the wing before the new +year; but nothing is likely to be met with beyond these save the +hybernators, already named in other lists, and some of the _Tineae_. + +It is a good plan to utilise your spare time during the dreary months of +winter by attending to your cabinet. Rearrange your specimens where +necessary, and see that all are properly labelled; remove all greasy +specimens, and deal with them as recommended on page 127; also renew the +supply of camphor or naphthaline in your drawers and store boxes. Time +may also be found for the construction of apparatus that is likely to be +required next season, and for repairing any that has been damaged during +the work of the last. + + + + +COLOURED PLATES + + +PLATE I (_Frontispiece_) + + 1.

In 2001, the Project +Gutenberg Literary Archive Foundation was created to provide a secure +and permanent future for Project Gutenberg-tm and future generations. +To learn more about the Project Gutenberg Literary Archive Foundation +and how your efforts and donations can help, see Sections 3 and 4 +and the Foundation web page at http://www.gutenberg.org/fundraising/pglaf. + + +Section 3.

Information about Donations to the Project Gutenberg +Literary Archive Foundation + +Project Gutenberg-tm depends upon and cannot survive without wide +spread public support and donations to carry out its mission of +increasing the number of public domain and licensed works that can be +freely distributed in machine readable form accessible by the widest +array of equipment including outdated equipment. Many small donations +($1 to $5,000) are particularly important to maintaining tax exempt +status with the IRS. + +The Foundation is committed to complying with the laws regulating +charities and charitable donations in all 50 states of the United +States. Compliance requirements are not uniform and it takes a +considerable effort, much paperwork and many fees to meet and keep up +with these requirements. We do not solicit donations in locations +where we have not received written confirmation of compliance. To +SEND DONATIONS or determine the status of compliance for any +particular state visit http://www.gutenberg.org/fundraising/donate + +While we cannot and do not solicit contributions from states where we +have not met the solicitation requirements, we know of no prohibition +against accepting unsolicited donations from donors in such states who +approach us with offers to donate. + +International donations are gratefully accepted, but we cannot make +any statements concerning tax treatment of donations received from +outside the United States. U.S. laws alone swamp our small staff. + +Please check the Project Gutenberg Web pages for current donation +methods and addresses. Donations are accepted in a number of other +ways including checks, online payments and credit card donations. +To donate, please visit: +http://www.gutenberg.org/fundraising/donate + + +Section 5.
