They exhaust the num- ber of the orthopterous and homopterous insects discussed by Henri Fabre. Chapters L to VIIL, XV., XVL and XIX. have already appeared, in certain cases under different titles and partly in an abbreviated form, in an interesting miscellany extracted from the Souvenirs, translated by Mr. Ber- nard Miall and published by the Century Company. This volume, Social Life in the Insect World, is illustrated with admirable photographs of insects, taken from life, and deserves a prominent place on the shelves of every lover of Fabre's works. vii Translator's Note At the moment of writing, the only one of the following essays that has been pub- lished before, in my translation, is the first of the three describing the White-faced Decticus, which appeared, in the summer of last year, in the English Review. Miss Frances Rodwell has again lent me the most valuable assistance in preparing this volume ; and I am indebted also to Mr. Osman Edwards and Mr. Stephen McKenna for their graceful rhymed versions of the oc- casional lyrics that adorn it.

Vlll CHAPTER I THE FABLE OF THE CICADA AND THE ANT T?AME is built up mainly of legend; in the ^ animal world, as in the world of men, the story takes precedence of history. In- sects in particular, whether they attract our attention in this way or in that, have their fair share in a folk-lore which pays but little regard to truth. For instance, who does not know the Cicada, at least by name? Where, in the entomological world, can we find a renown that equals hers? Her reputation as an inveterate singer, who takes no thought for the future, has formed a subject for our earliest exercises in repetition. In verses that are very easily learnt, she is shown to us, when the bitter winds begin to blow, quite destitute and hurrying to her neigh- bour, the Ant, to announce her hunger. The would-be borrower meets with a poor The Life of the Grasshopper welcome and with a reply which has re- mained proverbial and is the chief cause of the little creature's fame. Those two short lines, Voiis chantiez! Fen suis bien en aise. Eh bien, dansez maintenant/- with their petty malice, have done more for the Cicada's celebrity than all her talent as a musician. They enter the child's mind like a wedge and never leave it. To most of us, the Cicada's song is un- known, for she dwells in the land of the olive-trees; but we all, big and little, have heard of the snub which she received from the Ant. See how reputations are made ! A story of very doubtful value, offending as much against morality as against natural history; a nursery-tale whose only merit lies in its brevity: there we have the origin of a renown which will tower over the ruins of the centuries like Hop-o'-my-Thumb's boots and Little Red-Riding-Hood's basket. * You used to sing! I'm glad to know it. V^ell, try dancing for a change! 2 The Fable of the Cicada and the Ant The child is essentially conservative. Cus- tom and traditions become indestructible once they are confided to the archives of his memory. We owe to him the celebrity of the Cicada, whose woes he stammered in his first attempts at recitation. He preserves for us the glaring absurdities that are part and parcel of the fable : the Cicada will always be hungry when the cold comes, though there are no Cicadas left in the winter; she will always beg for the alms of a few grains of wheat, a food quite out of keeping with her delicate sucker; the sup- plicant is supposed to hunt for Flies and grubs, she who never eats ! Whom are we to hold responsible for these curious blunders? La Fontaine,^ who charms us in most of his fables with his exquisite delicacy of observation, is very ill- inspired in this case. He knows thoroughly his common subjects, the Fox, the Wolf, the Cat, the Goat, the Crow, the Rat, the Weasel and many others, whose sayings and doings he describes to us with delightful precision of detail. They are local char- acters, neighbours, housemates of his. Their * Jean de La Fontaine (1621-1695), the author of the world-famous Fables. — Translator's Note. The Life of the Grasshopper public and private life is spent under his eyes; but, where Jack Rabbit gambols, the Cicada is an entire stranger : La Fontaine never heard of her, never saw her. To him the famous singer is undoubtedly a Grass- hopper. Grandville,^ whose drawings have the same delicious spice of malice as the text itself, falls into the same error. In his illus- tration, we see the Ant arrayed like an industrious housewife. Standing on her threshold, beside great sacks of wheat, she turns a contemptuous back on the borrower, who is holding out her foot, I beg pardon, her hand. The second figure w^ears a great cartwheel hat, with a guitar under her arm and her skirt plastered to her legs by the wind, and is the perfect picture of a Grass- hopper. Grandville no more than La Fon- taine suspected the real appearance of the Cicada; he reproduced magnificently the general mistake. For the rest, La Fontaine, in his poor 'Jean Ignace Isidore Gerard (1803-1847), better known by his pseudonym of Grandville. a famous French caricaturist and illustrator of La Fontaine's Fables, Beranjrer's Chansons and the standard French editions of Robinson Crusoe and Gulliver's Travels. — Trans- lator's Note. The Fable of the Cicada and the Ant little story, only echoes another fabulist. The legend of the Cicada's sorry welcome by the Ant is as old as selfishness, that is to say, as old as the world. The children of Athens, going to school with their esparto- grass baskets crammed with figs and olives, were already mumbling it as a piece for recitation: " In winter,'' said they, " the Ants dry their wet provisions In the sun. Up comes a hungry Cicada begging. She asks for a few grains. The greedy hoarders reply, ' You used to sing in summer; now dance in win- ter.' " ' This, although a little more baldly put, is precisely La Fontaine's theme and is con- trary to all sound knowledge. * Sir Roger L'Estrange attributes the fable to Anianus and, as is usual in the English version, substitutes the Grasshopper for the Cicada. It may be interesting to quote his translation: " As the Ants were airing their provisions one winter, up comes a hungry Grasshopper to 'em and begs a charity. They told him that he should have wrought in summer, if he would not have wanted in winter. * Well,' says the Grasshopper, ' but I was not idle neither; for I sung out the whole season.' 'Nay then,' said they, * you shall e'en do well to make a merry year on't and dance in winter to the tune that you sung in summer.' " — Translator's Note. The Life of the Grasshopper Nevertheless the fable comes to us from Greece, which is preeminently the land of olive-trees and Cicadas. Was ^sop really the author, as tradition pretends? It is doubtful. Nor does it matter, after all: the narrator is a Greek and a fellow-countryman of the Cicada, whom he must know well enough. My village does not contain a peasant so ignorant as to be unaware of the absolute lack of Cicadas in winter; every tiller of the soil is familiar with the insect's primary state, the larva, which he turns over with his spade as often as he has occasion to bank up the olive-trees at the approach of the cold weather; he knows, from seeing it a thousand times along the paths, how this grub leaves the ground through a round pit of its own making, how it fastens on to some twig, splits its back, divests itself of its skin, now drier than shrivelled parchment, and turns into the Cicada, pale grass-green at first, soon to be succeeded by brown. The Attic peasant was no fool either : he had remarked that which cannot escape the least observant eye; he also knew what my rustic neighbours know so well. The poet, whoever he may have been, who invented the fable was writing under the best con- 6 The Fable of the Cicada and the Ant ditions for knowing all about these things. Then whence did the blunders in his story- arise? The Greek fabulist had less excuse than La Fontaine for portraying the Cicada of the books instead of going to the actual Cicada, whose cymbals were echoing at his side; heedless of the real, he followed tradi- tion. He himself was but echoing a more ancient scribe; he was repeating some legend handed down from India, the venerable mother of civilizations. Without knowing exactly the story which the Hindu's reed had put in writing to show the danger of a life led without foresight, we are entitled to be- lieve that the little dialogue set down was nearer to the truth than the conversation between the Cicada and the Ant. India, the great lover of animals, was incapable of committing such a mistake. Everything seems to tell us that the leading figure in the original fable was not our Cicada but rather some other creature, an insect if you will, whose habits corresponded fittingly with the text adopted. Imported into Greece, after serving for centuries to make the wise reflect and to amuse the children on the banks of the The Life of the Grasshopper Indus, the ancient story, perhaps as old as the first piece of economical advice vouch- safed by PaterfamlHas and handed down more or less faithfully from memory to memory, must have undergone an alteration In Its details, as do all legends which the course of the ages adapts to circumstances of time and place. The Greek, not possessing In his fields the insect of which the Hindu spoke, dragged in, as the nearest thing to It, the Cicada, even as in Paris, the modern Athens, the Cicada is replaced by the Grasshopper. The mischief was done. Henceforth ineradica- ble, since it has been confided to the memory of childhood, the mistake will prevail against an obvious truth. Let us try to rehabilitate the singer slan- dered by the fable. He is, I hasten to admit, an importunate neighbour. Every summer he comes and settles in his hundreds outside my door, attracted by the greenery of two tall plane-trees; and here, from sun- rise to sunset, the rasping of his harsh symphony goes through my head. Amid this deafening concert, thought is impossible: one*s ideas reel and whirl, are incapable of concentrating. When I have not profited by 8 The Fable of the Cicada and the Ant the early hours of the morning, my day is lost. Oh, little demon, plague of my dwelling which I should like to have so peaceful, they say that the Athenians used to rear you In a cage to enjoy your singing at their ease! One we could do with, perhaps, during the drowsy hour of digestion; but hundreds at a time, all rattling and drumming in our ears when we are trying to collect our thoughts, that is sheer torture ! You say that you were here first, do you? Before I came, you were in undisputed possession of the two plane- trees; and it is I who am the Intruder there. I agree. Nevertheless, muffle your drums, moderate your arpeggios, for the sake of your biographer ! Truth will have none of the absurd rig- marole which we find In the fable. That there are sometimes relations between the Cicada and the Ant Is most certain; only, these relations are the converse of what we are told. They are not made on the initiative of the Cicada, who is never de- pendent on the aid of others for his living; they come from the Ant, a greedy spoiler, who monopolizes every edible thing for her granaries. At no time does the Cicada go 9 The Life of the Grasshopper crying famine at the doors of the Ant-hills, promising honestly to repay principal and interest; on the contrary, it is the Ant who, driven by hunger, begs and entreats the singer. Entreats, do I say? Borrowing and repaying form no part of the pillager's habits. She despoils the Cicada, brazenly robs him of his possessions. Let us describe this theft, a curious point in natural history and, as yet, unknown. In July, during the stifling heat of the afternoon, when the insect populace, parched with thirst, vainly wanders around the limp and withered flowers in search of refresh- ment, the Cicada laughs at the general need. With that delicate gimlet, his rostrum, he broaches a cask in his inexhaustible cellar. Sitting, always singing, on the branch of a shrub, he bores through the firm, smooth bark swollen with sap ripened by the sun. Driving his sucker through the bung-hole, he drinks luxuriously, motionless and rapt in contemplation, absorbed in the charms of syrup and song. Watch him for a little while. We shall perhaps witness unexpected tribulation. There are many thirsty ones prowling around, in fact; they discover the well be- 10 The Fable of the Cicada and the Ant trayed by the sap that oozes from the margin. They hasten up, at first with some discretion, confining themselves to licking the fluid as it exudes. I see gathering around the meUifluous puncture Wasps, Flies, Ear- wigs, Sphex-wasps,^ Pomplli,^ Rose-chafers ^ and, above all, Ants. The smallest, In order to reach the well, slip under the abdomen of the Cicada, who good-naturedly raises himself on his legs and leaves a free passage for the intruders; the larger ones, unable to stand still for im- patience, quickly snatch a sip, retreat, take a walk on the neighbouring branches and then return and show greater enterprise. The coveting becomes more eager; the discreet ones of a moment ago develop Into turbulent aggressors, ready to chase away from the spring the well-sinker who caused it to gush forth. In this brigandage, the worst offenders * Cf. The Hunting Wasps, by J.

I have seen them nibbHng at the ends of the Cicada's legs; I have caught them tugging at the tips of his wings, cHmbIng on his back, tIckHng his antennse. One, greatly daring, went to the length, be- fore my eyes, of catching hold of his sucker and trying to pull It out. Thus worried by these pigmies and losing all patience, the giant ends by abandoning the well. He flees, spraying the robbers with his urine as he goes. What cares the Ant for this expression of supreme con- tempt! Her object is attained. She Is now the mistress of the spring, which dries up only too soon when the pump that made it flow ceases to v/ork. There is little of it, but that little is exquisite. It is so much to the good, enabling her to wait for another draught, acquired in the same fashion, as soon as the occasion presents itself. You see, the actual facts entirely reverse the parts assigned in the fable. The hard- ened beggar, who does not shrink from theft, is the Ant; the industrious artisan, gladly sharing his possessions with the suf- ferer, is the Cicada. I will mention one more detail; and the reversal of characters will stand out even more clearly. After five 12 The Fable of the Cicada and the Ant or six weekc of wassail, which is a long space of time, the singer, exhausted by the strain of life, drops from the tree. The sun dries up the body; the feet of the passers-by crush it. The Ant, always a highway-robber in search of spoil, comes upon it. She cuts up the rich dish, dissects it, carves it and reduces it to morsels which go to swell her hoard of provisions. It is not unusual to see a dying Cicada, with his wing still quivering in the dust, drawn and quartered by a gang of knackers. He Is quite black with them. After this cannibalistic proceeding, there is no question as to the true relations between the two insects. The ancients held the Cicada in high favour. Anacreon, the Greek Beranger,^ de- voted an ode to singing his praises in curi- ously exaggerated language : " Thou art almost like unto the gods," says he. The reasons which he gives for this apotheosis are none of the best. They con- sist of these three privileges : yriyevrfi, ana- drji, avai^ocfapnej earthborn, insensible to pain, bloodless. Let us not start reproaching ^Pierre Jean de Beranger (1780-1857), the popular French lyric poet. — Translator's Note. 13 The Life of the Grasshopper the poet for these blunders, which were ge- nerally believed at the time and perpetuated for very long after, until the observer's searching eyes were opened. Besides, it does not do to look so closely at verses whose chief merit lies in harmony and rhythm. Even in our own days, the Provengal poets, who are at least as familiar with the Cicada as Anacreon was, are not so very careful of the truth in celebrating the insect which they take as an emblem. One of my friends, a fervent observer and a scrupulous reahst, escapes this reproach. He has authorized me to take from his unpublished verse the following Provencal ballad, which depicts the relations between the Cicada and the Ant with strictly scientific accuracy. I leave to him the responsibility for his poetic images and his moral views, delicate flowers outside my province as a naturalist; but I can vouch for the truth of his story, which taUies with what I see every summer on the lilac-trees in my garden. 14 La Cigalo e la Fournigo I Jour de Dieu, queto caudf Beu terns per la cigalo Que, trefoulido, se regalo D'lino raisso de fid; beu terns per la meissoun.

Thus speaks my friend, in his expressive Provencal tongue, rehabilitating the Cicada, who has been so grossly libelled by the fabulist. TRANSLATOR S NOTE I am indebted for the following transla- tion to the felicitous pen of my friend Mr. Osman Edwards : THE CICADA AND THE ANT Ye gods, what heat! Cicada thrills With mad delight when fairy rills Submerge the corn in waves of gold, When, with bowed back and toil untold, His blade the songless reaper plies, For in dry throats song gasps and dies. This hour is thine: then, loud and clear, Thy cymbals clash, Cicada dear, 20 The Fable of the Cicada and the Ant Let mirrors crack, let belly writhe! Behold ! The man yet darts his scythe, Whose glitter lifts and drops again A lightning-flash on ruddy grain. With grass and water well supplied, His whetstone dangles at his side; The whetstone in its case of wood Has moisture for each thirsty mood; But he, poor fellow, pants and moans, The marrow boiling in his bones. Dost thirst. Cicada? Never mind! Deep in a young bough's tender rind Thy sharp proboscis bores a well. Whence, narrow^ly, sweet juices swell. Ah, soon what honied joj^s are thine To quaff a vintage so divine! In peace? Not always. . . . There's a band Of roving thieves (or close at hand) Who watched thee draw the nectar up And beg one drop with doleful cup. Beware, my love ! They humbly crave ; Soon each will prove a saucy knave. The merest sip? — 'Tis set aside. What's left? — They are not satisfied. All must be theirs, who rudely fling A rakish claw athwart thy wing; Next on thy back swarm up and down, From tip to toe, from tail to crown. 21 The Life of the Grasshopper On every side they fuss and fret, Provoking an impatient jet ; Thou leavest soon the sprinkled rind, Its robber-rascals, far behind; Thy well purloined, each grins and skips And licks the honey from her lips. No tireless, quenchless mendicant Is so persistent as the Ant; %y^ Wasps, Beetles, Hornets, Drones and Flies, Sharpers of every sort and size. Loafers, intent on ousting thee. All are less obstinate than she. To pinch thy toe, thy nose to tweak, To tickle face and loins, to sneak Beneath thy belly, who so bold? Give her the tiniest foothold, The slut will march from side to side Across thy wings in shameless pride. II Now here's a story that is told, Incredible, by men of old: Once starving on a winter's day By secret, miserable way Thou soughtest out the Ant and found Her spacious warehouse underground. That rich possessor in the sun Was busy drying, one by one, Her treasures, moist with the night's dew. Before she buried them from view 22 The Fable of the Cicada and the Ant In corn-sacks of sufficient size; Then didst thou sue with tearful eyes, Saj^ing, "Alas! This deadly breeze '* Pursues me everywhere; I freeze ** With hunger; let me fill (no more!) " My wallet from that copious store ; *' Next year, when melons are full-blown, " Be sure I shall repay the loan! " Lend me a little corn! " — Absurd! Of course she will not hear a word ; Thou wilt not win, for all thy pain, From bulging sacks a single grain. " Be off and scrape the binns! " she cries: " Who sang in June, in winter dies." Thus doth the ancient tail impart Fit moral for a miser's heart; Bids him all charity forget And draw his purse-strings tighter yet. May colic chase such scurvy knaves With pangs internal to their graves! A sorry fabulist, indeed. Who fancied that the winter's need Would drive thee to subsist, forlorn. On Flies, on grubs, on grains of corn ; No need was ever thine of those. For whom the honied fountain flows. What matters winter ? All thy kin • Beneath the earth are gathered in ; 22 The Life of the Grasshopper Thou sleepest with unwaking heart, While the frail body falls apart In rags that unregarded lie, Save by the Ant's rapacious eye. She, groping greedily, one day Makes of thy shrivelled corpse her prey ; Dissects the trunk, gnaws limb from limb. Concocts, according to her w^him, A salad such grim housewives know, A tit-bit saved for hours of snow. Ill That, gentlemen, is truly told, Unlike the fairy-tale of old ; But finds it favour in his sight, Who grabs at farthings, day and night? Pot-bellied, crooked-fingered, he Would rule the world with L.S.D. Such riff-raff spread the vulgar view That " artists are a lazy crew," That " fools must suffer." Silent be! When the Cicada taps the tree, You steal his drink ; when life has fled, You basely batten on the dead. 24 CHAPTER II THE CICADA: LEAVING THE BURROW TO come back to the Cicada after Reaumur ^ has told the insect's story- would be waste of time, save that the di- sciple enjoys an advantage unknown to the master. The great naturalist received the materials for his work from my part of the world; his subjects came by barge after being carefully preserved in spirits. I, on the other hand, live in the Cicada's company. When July comes, he takes possession of the enclosure right up to the threshold of the house. The hermitage is our joint pro- perty. I remain master indoors; but out of doors he is the sovereign lord and an ex- tremely noisy and abusive one. Our near neighbourhood and constant association ^ Rene Antoine Ferchault de Reaumur (1683-1757), inventor of the Reaumur thermometer and author of Memoires pour servir a I'histoire naturelle des insectes. — Translator's Note. 25 The Life of the Grasshopper have enabled me to enter Into certain details of which Reaumur could not dream. The first Cicadas appear at the time of the summer solstice. Along the much- trodden paths baked by the sun and hardened by the frequent passage of feet there open, level with the ground, round orifices about the size of a man's thumb. These are the exit-holes of the Cicada-larvae, who come up from the depths to undergo their transforma- tion on the surface. They are more or less everywhere, except In soil turned over by the plough. Their usual position Is in the driest spots, those most exposed to the sun, espe- cially by the side of the roads. Equipped with powerful tools to pass, if necessary, through sandstone and dried clay, the larva, on leaving the earth, has a fancy for the hardest places. One of the garden-paths, converted Into a little Inferno by the glare from a wall facing south, abounds In such exit-holes. I proceed, in the last days of June, to examine these recently abandoned pits. The soil Is so hard that I have to take my pickaxe to tackle it. The orifices are round and nearly an Inch In diameter. There is absolutely no rubbish around them, no mound of earth thrown up 26 The Cicada: leaving the Burrow outside. This is invariably the case : the Cicada's hole is never surmounted with a mole-hill, as are the burrows of the Geo- trupes/ or Dorbeetles, those other sturdy excavators. The manner of working ac- counts for this difference. The Dung- beetle progresses from the outside inwards; he commences his digging at the mouth of the well, which allows him to ascend and heap up on the surface the material which he has extracted. The larva of the Cicada, on the other hand, goes from the inside out- wards; the last thing that it does is to open the exit-door, which, remaining closed until the very end of the work, cannot be used for getting rid of the rubbish. The former goes in and makes a mound on the threshold of the home; the latter comes out and cannot heap up anything on a threshold that does not yet exist. The Cicada's tunnel runs to a depth of between fifteen and sixteen inches. It is cylindrical, winds slightly, according to the exigencies of the soil, and is always nearly perpendicular, for it is shorter to go that way. The passage is quite open throughout * Cf. The Life and Love of the Insect: chap. ix. — Translator's Note. 27 The Life of the Grasshopper Its length. It Is useless to search for the rub- bish which this excavation ought, one would think, to produce ; we see none anywhere. The tunnel ends in a blind alley, in a rather wider chamber, with level walls and not the least vestige of communication with any gallery prolonging the well. Reckoned by Its length and Its diameter, the excavation represents a volume of about twelve cubic inches. What has become of the earth removed? Sunk In very dry and very loose soil, the well and the chamber at the bottom ought to have crumbly walls, which would easily fall In, If nothing else had taken place but the work of boring. My surprise was great to find, on the contrary, coated surfaces, washed with a paste of clayey earth. They are not by a long way what one could call smooth, but at any rate their Irregularities are covered with a layer of plaster; and their slippery materials, soaked with some agglutinant, are kept In position. The larva can move about and climb nearly up to the surface and down again to Its refuge at the bottom without producing-, with Its clawed legs, landslips which would block the tube, making ascent difficult and 28 The Cicada: leaving the Burrow retreat impossible. The miner shores up his galleries with pit-props and cross-beams; the builder of underground railways strengthens his tunnels with a casing of brickwork; the Cicada's larva, which is quite as clever an engineer, cements its shaft so as to keep it open however long it may have to serve. If I surprise the creature at the moment when it emerges from the soil to make for a neighbouring branch and there undergo its transformation, I see it at once beat a prudent retreat and, without the slightest difficulty, run down again to the bottom of its gallery, proving that, even when the dwell- ing is on the point of being abandoned for good, it does not become blocked with earth. The ascending-shaft is not a piece of work improvised in a hurry, in the insect's im- patience to reach the sunlight; it is a regular manor-house, an abode in which the grub is meant to make a long stay. So the plastered walls tell us. Any such precaution would be superfluous in the case of a mere exit aban- doned as soon as bored. There is not a doubt but that we have here a sort of meteorolog^ical station in which observations are taken of the weather outside. Under- ground, fifteen inches down, or more, the 29 The Life of the Grasshopper larva ripe for its emergence is hardly able to judge whether the dimatic conditions be favourable. Its subterranean weather is too gradual in its changes to be able to supply it with the precise indications necessary for the most important action of its life, its es- cape into the sunlight for the metamorphosis. Patiently, for weeks, perhaps for months. It digs, clears and strengthens a perpendi- cular chimney, leaving at the surface, to keep It sequestered from the world without, a layer as thick as one's finger. At the bottom It makes Itself a recess more carefully built than the remainder. This Is Its refuge. Its waiting-room, where It rests If Its recon- noitring lead It to defer Its emigration. At the least suspicion of fine weather, It scram- bles up, tests the exterior through the thin layer of earth forming a lid and enquires Into the temperature and the degree of humidity of the air. If things do not bode well. If a heavy shower threaten or a blustering storm — events of supreme Importance when the de- licate Cicada throv/s off her skin — the pru- dent insect slips back to the bottom of the tube and goes on waiting. If, on the other hand, the atmospheric conditions be favour- 30 The Cicada: leaving the Burrow able, then the ceiling is smashed with a few strokes of the claws and the larva emerges from the well. Everything seems to confirm that the Cicada's gallery is a waiting-room, a me- teorological station where the larva stays for a long time, now hoisting itself near the sur- face to discover the state of the weather, now retreating to the depths for better shelter. This explains the convenience of a resting-place at the base and the need for a strong cement on walls which, without it, would certainly give way under continual comings and goings. What is not so easily explained is the com- plete disappearance of the rubbish corre- sponding with the space excavated. What has become of the twelve cubic Inches of earth yielded by an average well? There is nothing outside to represent them, nor any- thing Inside either. And then how, In a soil dry as cinders, Is the plaster obtained with which the walls are glazed? Larvae that gnaw Into wood, such as those of the Capricorn and the Buprestes,^ ^ The Capricorn, or Cerambyx beetle, lives in oak-trees; the Buprestis-beetles are found mostly in felled timber. — Translator's Note. 31 The Life of the Grasshopper for instance, ought to be able to answer the first question. They make their way inside a tree-trunk, boring galleries by eating the materials of the road which they open. De- tached in tiny fragments by the mandibles, these materials are digested. They pass through the pioneer's body from end to end, yielding up their meagre nutritive elements on the way, and accumulate behind, com- pletely blocking the road which the grub will never take again. The work of excessive division and subdivision, done either by the mandibles or the stomach, causes the digested materials to take up less room than the un- touched wood; and the result is a space In front of the gallery, a chamber In which the grub w^orks, a chamber which is greatly re- stricted in length, giving the prisoner just enough room to move about. Can It not be In a similar fashion that the Cicada-grub bores Its tunnel? Certainly the waste material flung up as It digs Its way does not pass through Its body; even If the soil were of the softest and most yielding character, earth plays no part whatever In the larva's food. But, after all, cannot the materials removed be simply shot back as the work proceeds? The Cicada remains 32 The Cicada: leaving the Burrow four years in the ground. This long hfe is not, of course, spent at the bottom of the well which we have described: this is just a place where the larva prepares for its emergence. It comes from elsewhere, doubt- less from some distance. It is a vagabond, going from one root to another and driving its sucker into each. When it moves, either to escape from the upper layers, which are too cold in winter, or to settle down at a better drinking-bar, it clears a road by fling- ing behind it the materials broken up by its pickaxes. This is undoubtedly the method. As v/ith the larvs of the Capricorn and the Buprestes, the traveller needs around him only the small amount of free room which his movements require. Damp, soft, easily compressed earth is to this larva what the digested pap is to the others. Such earth is heaped up without difficulty; it condenses and leaves a vacant space. The difficulty is one of a different kind with the exit-well bored in a very dry soil, which offers a marked resistance to com- pression so long as it retains its aridity. That the larva, when beginning to dig its passage, flung back part of the excavated materials into an earlier gallery which has now disap- 33 The Life of the Grasshopper peared Is fairly probable, though there is nothing In the condition of things to tell us so; but, If we consider the capacity of the well and the extreme difficulty of finding room for so great a volume of rubbish, our doubts return and we say to ourselves : " This rubbish demanded a large empty space, which itself was obtained by shifting other refuse no less difficult to house. The room required presupposes the existence of another space into which the earth extracted was shot." And so we find ourselves In a vicious circle, for the mere subsidence of materials flung behind would not be enough to explain so great a void. The Cicada must have a special method of disposing of the super- fluous earth. Let us try and surprise his secret. Examine a larva at the moment when it emerges from the ground. It is nearly al- ways more or less soiled with mud, some- times wet, sometimes dry. The digging- Implements, the fore-feet, have the points of their pickaxes stuck In a globule of slime; its other legs are cased In mud; Its back is spotted with clay. We are reminded of a scavenger v/ho has been stirring up sewage. 34 The Cicada: leaving the Burrow These stains are the more striking inasmuch as the creature comes out of exceedingly dry ground. We expected to see it covered with dust and we find it covered with mud. One more step in this direction and the problem of the well is solved. I exhume a larva which happens to be working at its exit-gallery. Very occasionally, I get a piece of luck like this, in the course of my digging; it would be useless for me to try for it, as there is nothing outside to guide my search. My welcome prize is just beginning its excavations. An inch of tunnel, free from any rubbish, and the waiting-room at the bottom represent all the work for the mo- ment. In what condition is the worker? We shall see. The grub is much paler in colour than those which I catch as they emerge. Its big eyes in particular are whitish, cloudy, squint- ing and apparently of little use for seeing. What good is sight underground? The eyes of the larvae issuing from the earth are, on the contrary, black and shining and indicate ability to see. When it makes its appearance in the sunshine, the future Cicada has to seek, occasionally at some distance from the exit-hole, the hanging 35 The Life of the Grasshopper branch on which the metamorphosis will be performed; and here sight will manifestly be useful. This maturity of vision attained during the preparation for the release is enough to show us that the larva, far from hastily improvising its ascending-shaft, works at it for a long time. Moreover, the pale and blind larva is bulkier than it is in the state of maturity. It is swollen with liquid and looks dropsical. If you take It in your fingers, a limpid humour oozes from the hinder part and moistens the whole body. Is this fluid, ex- pelled from the intestines, a urinary product? Is it just the residue of a stomach fed solely on sap? I will not decide the question and will content myself with calling It urine, merely for convenience. Well, this fountain of urine Is the key to the mystery. The larva, as It goes on and digs, sprinkles the dusty materials and makes them Into paste, which Is forthwith applied to the walls by abdominal pressure. The original dryness Is succeeded by plasticity. The mud obtained penetrates the Interstices of a rough soil; the more liquid part of It trickles In front; the remainder Is com- pressed and packed and occupies the empty 36 The Cicada: leaving the Burrow spaces in between. Thus is an unblocked tunnel obtained, without any refuse, because the dust and rubbish are used on the spot In the form of a mortar which is more com- pact and more homogeneous than the soil traversed. The larva therefore w^orks in the midst of clayey mire ; and this Is the cause of the stains that astonish us so much when we see It Issuing from excessively dry soil. The per- fect insect, though relieved henceforth from all mining labour, does not utterly abandon the use of Its bladder; a few drains of urine are preserved as a weapon of de- fence. When too closely observed. It dis- charges a spray at the Intruder and quickly flies away. In either form, the Cicada, his dry constitution notwithstanding, proves him- self a skilled irrigator. Dropsical though It be, the larva cannot carry sufficient liquid to moisten and turn Into compressible mud the long column of earth which has to be tunnelled. The reser- voir becomes exhausted and the supply has to be renewed. How is this done and when ? I think I see. The few wells which I have laid bare throughout their length, with the palns- 37 The Life of the Grasshopper taking care which this sort of digging de- mands, show me at the bottom, encrusted in the wall of the terminal chamber, a live root, sometimes as big as a lead-pencil, sometimes no thicker than a straw. The visible part of this root is quite small, barely a fraction of an inch. The rest is contained In the sur- rounding earth. Is the discovery of this sort of sap fortuitous? Or is it the result of a special search on the larva's part? The presence of a rootlet is so frequent, at least when my digging is skilfully conducted, that I rather favour the latter alternative. Yes, the Cicada-grub, when hollowing out its cell, the starting-point of the future chimney, seeks the Immediate neighbourhood of a small live root; it lays bare a certain portion, which continues the side wall with- out projecting. This live spot in the wall is, I think, the fount from which the contents of the urinary bladder are renewed as the need arises. When its reserves are ex- hausted by the conversion of dry dust Into mud, the miner goes down to his chamber, drives In his sucker and takes a deep draught from the cask built into the wall. With his jug well filled, he goes up again. He re- sumes his work, wetting the hard earth the 38 The Cicada: leaving the Burrow better to flatten it with his claws and reducing the dusty rubbish to mud which can be heaped up around him and leave a clear thorough- fare. That is how things must happen. So logic and the circumstances of the case tell us, in the absence of direct observation, which is not feasible here. If this root-cask fail, if moreover the reservoir of the intestine be exhausted, what will happen then? We shall learn from the following experiment. I catch a grub as it is leaving the ground. I put it at the bottom of a test-tube and cover it with a column of dry earth, not too closely packed. The column is nearly six inches high. The larva has just quitted an excavation thrice as deep, in soil of the same nature, but offering a much greater resistance. Now that it is buried under my short, sandy column, will it be capable of climbing to the surface? If it were a mere matter of strength, the issue would be certain. What can an obstacle without cohesion be to one that has just bored a hole through the hard ground? And yet I am assailed by doubts. To break down the screen that still separated it from the outer air, the larva has expended its last reserves of fluid. The flask is dry; 39 The Life of the Grasshopper and there is no way of replenishing it in the absence of a Hve root. My suspicion of faikire is well-founded. For three days I see the entombed one wasting itself in ef- forts without succeeding in rising an inch higher. The materials removed refuse to stay in position for lack of anything to bind them; they are no sooner pushed aside than they slip down again under the insect's legs. The labour has no perceptible result and has always to be done all over again. On the fourth day, the creature dies. With the water-can full, the result is quite different. I subject to the same experiment an insect whose work of self-deliverance is just beginning. It is all swollen with urinary humours which ooze out and moisten its whole body. This one's task is easy. The materials offer hardly any resistance. A little moisture, supplied by the miner's flask, converts them into mud, sticks them together and keeps them out of the way. The passage is opened, very irregular in shape, it is true, and almost filled up at the back as the ascent proceeds. It is as though the larva, recognizing the impossibility of renewing its store of fluid, were saving up the little which it possesses and spending no 40 The Cicada: leaving the Burrow more than is strictly necessary to enable It to escape as quickly as possible from its un- familiar surroundings. This economy is so well arranged that the insect reaches the surface at the end of ten days. 41 CHAPTER III THE CICADA: THE TRANSFORMATION THE exit-gate Is passed and left wide open, like a hole made with a large gimlet. For some time the larva wanders about the neighbourhood, looking for some aerial support, a tiny bush, a tuft of thyme, a blade of grass or the twig of a shrub. It finds it, climbs up and, head upwards, clings to it firmly with the claws of the fore-feet, which close and do not let go again. The other legs take part in sustaining it. If the position of the branch make this possible; if not, the two claws suffice. There follows a moment of rest to allow the supporting armiS to stiffen Into an immovable grip. First, the mesothorax splits along the middle of the back. The edges of the slit separate slowly and reveal the pale-green colour of the insect. Almost immediately afterwards, the prothorax splits also. The longitudinal fissure reaches the back of the 42 The Cicada: the Transformation head above and the metathorax below, with- out spreading farther. The wrapper of the skull breaks crosswise, in front of the eyes; and the red stemmata appear. The green portion uncovered by these ruptures swells and protrudes over the whole of the meso- thorax. We see slow palpitations, alternate contractions and distensions due to the ebb and flow of the blood. This hernia, work- ing at first out of sight, is the wedge that made the cuirass split along two crossed lines of least resistance. The skinning-operation makes rapid pro- gress. Soon the head is free. Then the rostrum and the front legs gradually leave their sheaths. The body is horizontal, with the ventral surface turned upwards. Under the wide-open carapace appear the hinder legs, the last to be released. The wings are distended with moisture. They are still rumpled and look like stumps bent into a bow. This first phase of the transformation has taken but ten minutes. There remains the second, which lasts longer. The whole of the insect is free, ex- cept the tip of the abdomen, which is still contained in its scabbard. The cast skin continues to grip the twig. Stiffening as the 43 The Life of the Grasshopper result of quick desiccation, it preserves with- out change the attitude which it had at the start. It forms the pivot for what is about to follow. Fixed to his slough by the tip of the abdomen, which is not yet extracted, the Cicada turns over perpendicularly, head downwards. He is pale-green, tinged with yellow. The wings, until now compressed into thick stumps, straighten out, unfurl, spread under the rush of the liquid with which they are gorged. When this slow and delicate operation is ended, the Cicada, with an almost imperceptible movement, draws himself up by sheer strength of loin and resumes a normal position, head up- wards. The fore-legs hook on to the empty skin; and at last the tip of the belly is drawn from its sheath. The extraction is over. The work has required half an hour alto- gether. Here is the whole insect, freed from its mask, but how different from what it will be presently! The wings are heavy, moist, transparent, with their veins a light green. The prothorax and mesothorax are barely tinged with brown. All the rest of the body is pale-green, whitish in places. It must 44 The Cicada: the Transformation bathe in air and sunshine for a long time before strength and colour can come to its frail body. About two hours pass without producing any noticeable change. Hanging to his cast skin by his fore-claws only, the Cicada sways at the least breath of air, still feeble and still green. At last the brown tinge appears, becomes more marked and is soon general. Half an hour has effected the change of colour. Slung from the sus- pension-twig at nine o'clock in the morning, the Cicada flies away, before my eyes, at half-past twelve. The cast skin remains, intact, save for its fissure, and so firmly fastened that the rough weather of autumn does not always succeed in bringing it to the ground. For some months yet, even during the winter, one often meets old skins hanging in the bushes in the exact position adopted by the larva at the moment of its transformation. Their horny nature, something like dry parchment, ensures a long existence for these relics. Let us hark back for a moment to the gymnastic feat which enables the Cicada to leave his scabbard. At first retained by the tip of the abdomen, which Is the last part to remain In its case, the Cicada turns over 45 The Life of the Grasshopper perpendicularly, head downwards. This somersault allows him to free his wings and legs, after the head and chest have already- made their appearance by cracking the armour under the pressure of a hernia. Now comes the time to free the end of the abdomen, the pivot of this inverted attitude. For this purpose, the insect, with a laborious movement of its back, draws itself up, brings its head to the top again and hooks itself with its fore-claws to the cast skin. A fresh support is thus obtained, enabling it to pull the tip of its abdomen from its sheath. There are therefore two means of sup- port : first the end of the belly and then the front claws; and there are two principal movements : in the first place the downward somersault, in the second place the return to the normal position. These gymnastics de- mand that the larva shall fix itself to a twig, head upwards, and that it shall have a free space beneath it. Suppose that these con- ditions were lacking, thanks to my wiles : what would happen? That remained to be seen. I tie a thread to the end of one of the hind-legs and hang the larva up in the peace- ful atmosphere of a test-tube. My thread 46 The Cicada: the Transformation Is a plumb-line which will remain vertical, for there is nothing to interfere with it. In this unwonted posture, which places its head at the bottom at a time when the near ap- proach of the transformation demands that it should be at the top, the unfortunate crea- ture for a long time kicks about and strug- gles, striving to turn over and to seize with its fore-claws either the thread by which it hangs or one of its own hind-legs. Some of them succeed in their efforts, draw them- selves up as best they can, fasten themselves as they wish, despite the difficulty of keeping their balance, and effect their metamorphosis without Impediment. Others wear themselves out In vain. They do not catch hold of the thread, they do not bring their heads upwards. Then the trans- formation Is not accomplished. Sometimes the dorsal rupture takes place, leaving bare the mesothorax swollen Into a hernia, but the shelling proceeds no farther and the Insect soon dies. More often still the larva per- ishes Intact, without the least fissure. Another experiment. I place the larva In a glass jar with a thin bed of sand, which makes progress possible. The animal moves along, but is not able to hoist itself up any- 47 The Life of the Grasshopper where : the slippery sides of the glass prevent this. Under these conditions, the captive expires without trying to transform itself. I have known exceptions to this mis- erable ending; I have sometimes seen the larva undergo a regular metamorphosis on a layer of sand thanks to peculiarities of equilibrium which were very difficult to dis- tinguish. In the main, when the normal atti- tude or something very near it is impossible, metamorphosis does not take place and the insect succumbs. That is the general rule. This result seems to tell us that the larva Is capable of opposing the forces which are at work In it when the transformation is at hand. A cabbage-silique, a pea-pod Invari- ably burst to set free their seeds. The Cicada-larva, a sort of pod containing, by way of seed, the perfect Insect, Is able to control Its dehiscence, to defer It until a more opportune moment and even to sup- press It altogether In unfavourable circum- stances. Convulsed by the profound revo- lution that takes place In Its body on the point of transfiguration, but at the same time warned by Instinct that the conditions are not good, the Insect makes a desperate re- sistance and dies rather than consent to open. 48 The Cicada: the Transformation Apart from the trials to which my curi- osity subjects it, I do not see that the Cicada- larva is exposed to any danger of perishing in this way. There is always a bit of brush- wood of some kind near the exit-hole. The newly-exhumed insect climbs on it; and a few minutes are enough for the animal pod to split down the back. This swift hatching has often been a source of trouble to me in my studies. A larva appears on the hills not far from my house. I catch sight of it just as it is fastening on the twig. It would form an interesting subject of observation indoors. I place it in a paper bag, together with the stick that carries it, and hurry home. This takes me a quarter of an hour, but it is labour lost: by the time that I arrive, the green Cicada is almost free. I shall not see what I was bent on seeing. I had to abandon this method of obtaining Informa- tion and be content with an occasional lucky find within a few^ yards of my door. " Everything Is in everything," as Jacotot the pedagogue ^ used to say. In connection * Joseph Jacotot (1770-1840), a famous French edu- cator, whose methods aroused a great deal of discuss- ion.

According to Aristotle, CIcadse were a highly-appreciated dish among the Greeks. I am not acquainted with the great naturalist's text: humble vil- lager that I am, my library possesses no such treasure. I happen, however, to have before me a venerable tome which can tell me just what I want to know. I refer to Matthiolus' Commentaries on Dioscorides^ As an emi- nent scholar, who must have known his Aristotle very well, Matthiolus inspires me with complete confidence. Now he says : " Minim non est quod dixerit Aristoteles, cicadas esse gustu suavissimas antequam tettigometra rumpatur cortex.'* Knowing that tettigometra^ or mother of the Cicada, Is the expression used by the ancients to denote the larva, we see that, according to Aristotle, the CIcadae possess a flavour most delicious to the taste before the bark or outer covering of the matrix bursts. * Pletro Andrea Mattioli (1500-1577), known as Matthiolus, a physician and naturalist who practised at Siena and Rome. His Commentaries on Dioscorides were published in Italian, at Venice, in 1544 and in Latin in 1554. — Translator's Note. 50 The Cicada: the Transformation This detail of the unbroken covering tells us at what season the toothsome dainty should be picked. It cannot be in winter, when the earth is dug deep by the plough, for at that time there Is no danger of the larva's hatching. People do not recommend an utterly superflous precaution. It Is there- fore In summerj at the period of the emer- gence from underground, when a good search will discover the larvse, one by one, on the surface of the soil. This Is the real moment to take care that the wrapper is unbroken. It Is the moment also to hasten the gathering and the preparations for cook- ing: In a very few minutes the wrapper will burst. Are the ancient culinary reputation and that appetizing epithet, suavissimas giistii, well-deserved? We have an excellent oppor- tunity: let us profit by It and restore to honour, If the occasion warrant It, the dish extolled by Aristotle.

Would it not be a meritorious work to give the epicures their tett'igometr^e again? On a morning in July, when the sun is up and has invited the Cicadae to leave the ground, the whole household, big and little, go out searching. There are five of us en- gaged in exploring the enclosure, especially the edges of paths, which yield the best re- sults. To prevent the skin from bursting, as each larva is found I dip it into a glass of water. Asphyxia will stay the work of metamorphosis. After two hours of careful seeking, when every forehead is streaming with perspiration, I am the owner of four larv£, no more. They are dead or dying in their preserving bath; but this does not matter, since they are destined for the frying-pan. The method of cooking is of the simplest, so as to alter as little as possible the flavour reputed to be so exquisite : a few drops of oil, a pinch of salt, a little onion and that is all. There Is no conciser recipe In the whole of La Cinsiniere hoiirgeoise. At din- ner, the fry Is divided fairly among all of us hunters. 52 The Cicada: the Transformation The stuff is unanimously admitted to be eatable. True, we are people blessed with good appetites and wholly unprejudiced stomachs. There is even a slightly shrimpy flavour which would be found in a still more pronounced form in a hrochette of Locusts. It is, however, as tough as the devil and anything but succulent; we really feel as if we were chewing bits of parchment. I will not recommend to anybody the dish extolled by Aristotle. Certainly, the renowned animal-historian was remarkably well-informed as a rule. His royal pupil sent on his behalf to India, the land at that time so full of mystery, for the curiosities most impressive to Mace- donian eyes; he received by caravan the Elephant, the Panther, the Tiger, the Rhinoceros, the Peacock; and he described them faithfully. But, in Macedonia itself, he knew the insect only through the peasant, that stubborn tiller of the soil, who found the tettigometra under his spade and was the first to know that a Cicada comes out of it. Aristotle, therefore, in his immense un- dertaking, was doing more or less what Pliny was to do later, with a much greater amount of artless credulity. He listened to 53 The Life of the Grasshopper the chit-chat of the country-side and set It down as veracious history. Rustic waggery is world-famous. The countryman is always ready to jeer at the trifles which we call science; he laughs at whoso stops to examine an insignificant in- sect; he goes into fits of laughter if he sees us picking up a pebble, looking at it and putting it in our pocket. The Greek peasant excelled in this sort of thing. He told the townsman that the tettigomctra w^as a dish fit for the gods, of an incomparable flavour, siiavlssima gustii. But, while making his victim's mouth water with hyperbolical praises, he put it out of his power to satisfy his longings, by laying down the essential condition that he must gather the delicious morsel before the shell had burst. I should like to see any one try to get together the material for a sufiiciently copious dish by gathering a few handfuls of tettigometra just coming out of the earth, when my squad of five took two hours to find four larvae on ground rich in Cicadas. Above all, mind that the skin does not break during your search, which will last for days and days, whereas the bursting takes place In a few minutes. My opinion 54 The Cicada: the Transformation is that Aristotle never tasted a fry of tet- tigometra; and my own culinary experience is my witness. He is repeating some rustic jest in all good faith. His heavenly dish is too horrible for words. Oh, what a fine collection of stories I too could make about the Cicada, if I listened to all that my neighbours the peasants tell me I I will give one particular of his history and one alone, as related in the country. Have you any renal infirmity? Are you dropsical at all? Do you need a powerful depurative? The village pharmacopoeia is unanimous in suggesting the Cicada as a sovran remedy. The insects are collected in summer, in their adult form. They are strung together and dried in the sun and are fondly preserved in a corner of the press. A housewife would think herself lacking in prudence if she allowed July to pass without threading her store of them. Do you suffer from irritation of the kid- neys, or perhaps from stricture? Quick, have some Cicada-tea ! Nothing, they tell me, is so efficacious. I am duly grateful to the good soul who once, as I have since heard, made me drink a concoction of the sort, without my knowing it, for some 55 The Life of the Grasshopper trouble or other; but I remain profoundly incredulous. I am struck, however, by the fact that the same specific was recommended long ago by Dioscorides. The old Cilician doctor tells us : ^^Cicadtf, quce htassata mandiintur, ve- sica doloribiis prosunt.'^ ^ Ever since the far-off days of this patri- arch of materia medica, the Provencal peas- ant has retained his faith in the remedy re- vealed to him by the Greeks who brought the olive, the fig-tree and the vine from PhocjEa. One thing alone is changed: Di- oscorides advises us to eat our Cicadas roasted; nowadays they are boiled and taken as an infusion. The explanation given of the insect*s diuretic properties is wonderfully ingenuous. The Cicada, as all of us here know, shoots a sudden spray of urine, as It flies away, In the face of any one who tries to take hold of It. He Is therefore bound to hand on his powers of evacuation to us. Thus must Dioscorides and his contemporaries have * " Cicadae eaten roasted are good for pains in the bladder." 56 The Cicada: the Transformation argued; and thus does the peasant of Pro- vence argue to this day. O my worthy friends, what would you say if you knew the virtues of the tettigometra, which is capable of mixing mortar with its urine to build a meteorological station withal I You would be driven to borrow the hyperbole of Rabelais, who shows us Gar- gantua seated on the towers of Notre-Dame and drowning with the deluge from his mighty bladder so many thousand Paris loafers, not to mention the women and children 1 57 CHAPTER IV THE CICADA: HIS MUSIC T>Y his own confession, Reaumur never -■-' heard the Cicada sing; he never saw fhe insect ahve. It reached him from the coun- try round Avignon preserved in spirits and a goodly supply of sugar. These conditions were enough to enable the anatomist to give an exact description of the organ of sound; nor did the master fail to do so : his pene- trating eye clearly discerned the construction of the strange musical-box, so much so that his treatise upon it has become the fountain- head for any one who wants to say a few words about the Cicada's song. With him the harvest was gathered; it but remains to glean a few ears which the disciple hopes to make into a sheaf. I have more than enough of what Reaumur lacked : I hear rather more of these deafening symphonists than I could wish; and so I shall perhaps obtain a little fresh light on a sub- 58 The Cicada: his Music ject that seems exhausted. Let us therefore go back to the question of the Cicada's song, repeating only so much of the data acquired as may be necessary to make my explanation clear. In my neighbourhood I can capture five species of Cicadae, namely, Cicada plebeia, Lin. ; C orni, Lin. ; C. hematodes, Lin. ; C. atra, Oliv. ; and C pygmaa, Oliv. The first two are extremely common; the three others are rarities, almost unknown to the country- folk. The Common Cicada is the biggest of the five, the most popular and the one whose mu- sical apparatus is usually described. Under the male's chest, immediately behind the hind-legs, are two large semicircular plates, overlapping each other slightly, the right plate being on the top of the left. These are the shutters, the lids, the dampers, in short the opercula of the organ of sound. Lift them up. You then see opening, on either side, a roomy cavity, known in Pro- vence by the name of the chapel (// capello) . The two together form the church {la gleiso). They are bounded In front by a soft, thin, creamy-yellow membrane; at the back by a dry pellicle, iridescent as a soap- 59 The Life of the Grasshopper bubble and called the mirror (miraii) in the Provencal tongue. The church, the mirrors and the lids are commonly regarded as the sound-producing organs. Of a singer short of breath It Is said that he has cracked his mirrors {a li mirau creba) . Picturesque language says the same thing of an uninspired poet. Acoustics give the lie to the popular belief. You can break the mirrors, remove the lids with a cut of the scissors, tear the yellow front membrane and these mutilations will not do away with the Cicada's song: they simply modify It, weaken It slightly. The chapels are resonators. They do not pro- duce sound, they Increase It by the vibrations of their front and back membranes; they change It as their shutters are opened more or less wide. The real organ of sound is seated else- where and Is not easy to find, for a novice. On the other side of each chapel, at the ridge joining the belly to the back, Is a slit bounded by horny walls and m.asked by the lowered lid. Let us call It the window. This open- ing leads to a cavity or sound-chamber deeper than the adjacent chapel, but much less wide. Immediately behind the attachment of the 60 The Cicada: his Music rear wings is a slight, almost oval protu- berance, which Is distinguished by Its dull- black colour from the silvery down of the surrounding skin. This protuberance is the outer wall of the sound-chamber. Let us make a large cut in it. We now lay bare the sound-producing apparatus, the cymbal. This is a little dry, white mem- brane, oval-shaped, convex on the outside, crossed from end to end of its longer diameter by a bundle of three or four brown nervures, which give it elasticity, and fixed all round in a stiff frame. Imagine this bulging scale to be pulled out of shape from within, flattening slightly and then quickly recovering Its original convexity owing to the spring of Its nervures. The drawing in and blowing out will produce a clicking sound. Twenty years ago, all Paris went mad over a silly toy called the Cricket, or Cri-cri, if I remember rightly. It consisted of a short blade of steel, fastened at one end to a metallic base. Alternately pressed out of shape with the thumb and then released, the said blade, though possessing no other merit, gave out a very irritating click; and nothing more was needed to make it popular. The 6i The Life of the Grasshopper Cricket's vogue is over. Oblivion has done justice to it so drastically that I doubt if I shall be understood when I recall the once famous apparatus. The membranous cymbal and steel Cricket are similar Instruments. Both are made to rattle by pushing an elastic blade out of shape and restoring It to its original condi- tion. The Cricket was bent out of shape with the thumb. Hov/ is the convexity of the cym- bals modified? Let us go back to the church and break the yellow curtain that marks the boundary of each chapel In front. Two thick muscular columns come In sight, of a pale orange colour, joined together in the form of a V, with Its point standing on the Insect's median line, on the lower surface. Each of these fleshy columns ends abruptly at the top, as though lopped off; and from the truncated stump rises a short, slender cord which Is fastened to the side of the cor- responding cymbal. There you have the whole mechanism, which is no less simple than that of the metal Cricket. The two muscular columns con- tract and relax, shorten and lengthen. By means of the terminal thread each tugs at its cymbal, pulling It down and forthwith let- 62 The Cicada: his Music ting It spring back of itself. Thus are the two sound-plates made to vibrate. Would you convince yourself of the ef- ficacy of this mechanism? Would you make a dead but still fresh Cicada sing? Nothing could be simpler. Seize one of the muscular columns with the pincers and jerk it gently. The dead Cri-cri comes to life again; each jerk produces the clash of the cymbal. The sound is very feeble, I admit, deprived of the fulness which the living virtuoso obtains with the aid of his sound-chambers; never- theless the fundamental element of the song is produced by this anatomical trick. Would you on the other hand silence a live Cicada, that obstinate melomaniac who, when you hold him prisoner in your fingers, bewails his sad lot as garrulously as, just now, he sang his joys In the tree? It is no use to break open his chapels, to crack his mirrors : the shameful mutilation would not check him. But insert a pin through the side slit which we have called the window and touch the cymbal at the bottom of the sound- chamber. A tiny prick; and the perforated cymbal is silent. A similar operation on the other side renders the insect mute, though it remains as vigorous as before, showing 63 The Life of the Grasshopper no perceptible wound. Any one unacquainted with the method of procedure stands amazed at the result of my pin-prick, when the utter destruction of the mirrors and the other ac- cessories of the church does not produce silence. A tiny and in no way serious stab has an effect which is not caused even by evisceration. The lids, those firmly fitted plates, are stationary. It is the abdomen itself which, by rising and falling, causes the church to open and shut. When the abdomen is low- ered, the lids cover the chapels exactly, to- gether with the windows of the sound- chambers. The sound is then weakened, muffled, stifled. When the abdomen rises, the chapels open, the windows are unob- structed and the sound acquires its full strength. The rapid oscillations of the belly, therefore, synchronizing with the contrac- tions of the motor-muscles of the cymbals, determine the varying volume of the sound, which seems to come from hurried strokes of a bow. When the weather is calm and warm, about the middle of the day, the Cicada's song is divided into strophes of a few sec- onds' duration, separated by short pauses. 64 The Cicada: his Music The strophe begins abruptly. In a rapid crescendo, the abdomen oscillating faster and faster, it acquires its maximum volume; it keeps up the same degree of strength for a few seconds and then becomes gradually weaker and degenerates into a tremolo which decreases as the belly relapses into rest. With the last pulsations of the abdomen comes silence, which lasts for a longer or shorter time according to the condition of the atmosphere. Then suddenly we hear a new strophe, a monotonous repetition of the first; and so on indefinitely. It often happens, especially during the sultry evening hours, that the insect, drunk with sunshine, shortens and even entirely suppresses the pauses. The song is then con- tinuous, but always with alternations of crescendo and decrescendo. The first strokes of the bow are given at about seven or eight o'clock in the morning; and the orchestra ceases only with the dying gleams of the twilight, at about eight o'clock in the even- ing. Altogether the concert lasts the whole round of the clock. But, if the sky be over- cast, if the wind blow cold, the Cicada is dumb. The second species is only half the size 65 The Life of the Grasshopper of the Common Cicada and is known in the district by the name of the Cacan, a fairly- accurate imitation of his pecuHar rattle. This is the Ash Cicada of the naturalists; and he is far more alert and more suspicious than the first. His harsh loud song consists of a series of Can! Can! Can! Can! with not a pause to divide the ode into strophes. Its monotony and its harsh shrillness make it a most unpleasant ditty, especially when the orchestra is composed of some hundreds of executants, as happens in my two plane-trees during the dog-days. At such times it is as though a heap of dry walnuts were being shaken in a bag until the shells cracked. This irritating concert, a veritable torment, has only one slight advantage about it: the Ash Cicada does not start quite so early in the morning as the Common Cicada and does not sit up so late at night. Although constructed on the same funda- mental principles, the vocal apparatus dis- plays numerous peculiarities which give the song its special character. The sound- chamber is entirely lacking, which means that there is no entrance-window either. The cymbal is uncovered, just behind the insertion of the hind-wing. It again is a dry, white 66 The Cicada: his Music scale, convex on the outside and crossed by a bundle of five red-brown nervures. The first segment of the abdomen thrusts forward a short, wide tongue, which is quite rigid and of which the free end rests on the cymbal. This tongue may be compared with the blade of a rattle which, instead of fitting into the teeth of a revolving wheel, touches the nervures of the vibrating cymbal more or less closely. The harsh, grating sound must, I think, be partly due to this. It is hardly possible to verify the fact when holding the creature in our fingers : the startled Cacan does anything at such times rather than emit his normal song. The lids do not overlap ; on the contrary, they are separated by a rather wide interval. With the rigid tongues, those appendages of the abdomen, they shelter one half of the cymbals, the other half of which is quite bare. The abdomen, when pressed with the finger, does not open to any great extent where it joins the thorax. For the rest, the insect keeps still when it sings; it knows nothing of the rapid quivering of the belly that modulates the song of the Common Cicada. The chapels are very small and al- most negligible as sounding-boards. There 67 The Life of the Grasshopper are mirrors, it is true, but insignificant ones, measuring scarcely a twenty-fifth of an inch. In short, the mechanism of sound, which is so highly developed in the Common Cicada, is very rudimentary here. How then does the thin clash of the cymbals manage to gain in volume until it becomes intolerable? The Ash Cicada is a ventriloquist. If we examine the abdomen by holding it up to the light, we see that the front two thirds are translucent. Let us snip off the opaque third part that retains, reduced to the strictly indispensable, the organs essential to the propagation of the species and the preserva- tion of the individual. The rest of the belly is wide open and presents a spacious cavity, with nothing but its tegumentary walls, ex- cept in the case of the dorsal surface, which is lined with a thin layer of muscle and serves as a support to the slender digestive tube, which is little more than a thread. The large receptacle, forming nearly half of the insect's total bulk, is therefore empty, or nearly so. At the back are seen the two motor pillars of the cymbals, the two mus- cular columns arranged in a V. To the right and left of the point of this V gleam the two tiny mirrors ; and the empty space is 68 The Cicada: his Music continued between the two branches into the depths of the thorax. "This hollow belly and Its thoracic comple- ment form an enormous resonator, unap- proached by that of any other performer In our district. If I close with my finger the orifice In the abdomen which I have just clipped, the sound becomes lower, in con- formity with the laws affecting organ-pipes; if I fit a cylinder, a screw of paper, to the mouth of the open belly, the sound becomes louder as well as deeper. With a paper funnel properly adjusted, its wide end thrust Into the mouth of a test-tube acting as a sounding-board, we have no longer the shrilling of the Cicada but something very near the bellowing of a Bull. My small chil- dren, happening to be there at the moment when I am making my acoustic experiments, run away scared. The familiar Insect in- spires them with terror. "^The harshness of the sound appears to be due to the tongue of the rattle rasping the nervures of the vibrating cymbals; its in- tensity may no doubt be ascribed to the spa- cious sounding-board of the belly. Assuredly one must be passionately enamoured of song thus to empty one's belly and chest in order 69 The Life of the Grasshopper to make room for a musical-box. The essen- tial vital organs are reduced to the minimum, are confined to a tiny corner, so as to leave a greater space for the sounding-cavity. Song comes first; all the rest takes second place. It is a good thing that the Ash Cicada does not follow the teaching of the evolutionists. If, becoming more enthusiastic from genera- tion to generation, he were able by pro- gressive stages to acquire a ventral sounding- board fit to compare with that which my paper screws give him, my Provence, peopled as it is with Cacans, would one day become uninhabitable. After the details which I have already given concerning the Common Cicada, it seems hardly necessary to say how the insup- portable chatterbox of the Ash is rendered dumb. The cymbals are clearly visible on the outside. You prick them with the point of a needle. Complete silence follows in- stantly. Why are there not in my plane- trees, among the dagger-wearing insects, auxiliaries who, like myself, love quiet and who would devote themselves to that task! A mad wish ! A note would then be lacking in the majestic harvest symphony. 70 The Cicada: his Music The Red Cicada (C. hematodes) is a little smaller than the Common Cicada. He owes his name to the blood-red colour that takes the place of the other's brown on the veins of the wings and some other lineaments of the body. He is rare. I come upon him occa- sionally in the hawthorn-bushes. As regards his musical apparatus, he stands half-way be- tween the Common Cicada and the Ash Cicada. He has the former's oscillation of the belly, which increases or reduces the strength of the sound by opening or closing the church; he possesses the latter's exposed cymbals, unaccompanied by any sound- chamber or window. The cymbals therefore are bare, immedi- ately after the attachment of the hind-wings. They are white, fairly regular in their con- vexity and boast eight long, parallel nervures of a ruddy brown and seven others which are much shorter and which are inserted singly in the intervals between the first. The lids are small and scolloped at their inner edge so as to cover only half of the corresponding chapel. The opening left by the hollow in the lid has as a shutter a little pallet fixed to the base of the hind-leg, which, by folding itself against the body or lifting slightly, 71 The Life of the Grasshopper keeps the aperture either shut or open. The other Cicada have each a similar appendage, but in their case it is narrower and more pointed. Moreover, as with the Common Cicada, the belly moves freely up and down. This heaving movement, combined with the play of the femoral pallets, opens and closes the chapels to varying extents. The mirrors, though not so large as the Common Cicada's, have the same appear- ance. The membrane that faces them on the thorax side is white, oval and very delicate and is tight-stretched when the abdomen Is raised and flabby and wrinkled when the ab- domen is lowered. In Its tense state It seems capable of vibration and of increasing the sound. The song, modulated and subdivided Into strophes, suggests that of the Common Cicada, but Is much less objectionable. Its lack of shrillness may well be due to the absence of any sound-chambers. Other things being equal, cymbals vibrating unco- vered cannot possess the same Intensity of sound as those vibrating at the far end of an echoing vestibule. The noisy Ash Cicada also, it Is true, lacks that vestibule; but he ^2 The Cicada: his Music amply makes up for its absence by the enormous resonator of his belly. I have never seen the third Cicada, sketched by Reaumur and described by Olivier ^ under the name of C. tomentosa. The species is known in Provence, so this and that one tells me, by the name of the Cigalon, or rather Cigaloun, the Little Cigale or Cicada. This designation is unknown in my neighbourhood. I possess two other specimens which Re- aumur probably confused with the one of which he gives us a drawing. One is the Black Cicada (C. atra, Oliv.), whom I came across only once; the other is the Pigmy Ci- cada (C pygmaa, Oliv.), vv^hom I have picked up pretty often. I will say a few words about this last one. He is the smallest member of the genus in my district, the size of an average Gad-fly, and measures about three-quarters of an inch in length. His cymbals are transparent, with three opaque veins, are scarcely sheltered by ' Guillaume Antoine Olivier (1756-1814), a distin- guished French entomologist, author of an Histoire na- turelle des coleopteres, in six volumes (1789-1808), and part author of the nine volumes devoted to a Diction- naire de I'histoire naturelle des insectes in the Ency- clopedie methodique (1789-1819). — Translator's Note. 73 The Life of the Grasshopper a fold in the skin and are in full view, with- out any sort of entrance-lobby or sound- chamber. I may remark, in terminating our survey, that the entrance-lobby exists only in the Common Cicada ; all the others are with- out it. The dampers are separated by a wide in- terval and allow the chapels to open wide. The mirrors are comparatively large. Their shape suggests the outline of a kidney-bean. The abdomen does not heave when the insect sings; it remains stationary, like the Ash Cicada's. Hence a lack of variety in the melody of both. The Pigmy Cicada's song is a monotonous rattle, pitched in a shrill key, but faint and hardly perceptible a few steps away in the calm of our enervating July afternoons. If ever a fancy seized him to forsake his sun- scorched bushes and to come and settle down in force in my cool plane-trees — and I wish that he would, for I should much like to study him more closely — this pretty little Cicada would not disturb my solitude as the frenzied Cacan does. We have now ploughed our way through the descriptive part; we know the instrument of sound so far as its structure is concerned. 74 The Cicada: his Music In conclusion, let us ask ourselves the object of these musical orgies. What is the use of all this noise? One reply is bound to come : it is the call of the males summoning their mates; it is the lovers' cantata. I will allow myself to discuss this answer, which is certainly a very natural one. For fifteen years the Common Cicada and his shrill associate, the Cacan, have thrust their society upon me. Every summer for two months I have them before my eyes, I have them In my ears. Though I may not listen to them gladly, I observe them with a cert- ain zeal. I see them ranged In rows on the smooth bark of the plane-trees, all with their heads upwards, both sexes interspersed with a few Inches between them. With their suckers driven into the tree, they drink, motionless. As the sun turns and moves the shadow, they also turn around the branch with slow lateral steps and make for the best-lighted and hottest surface. Whether they be working their suckers or moving their quarters, they never cease singing. Are we to take the endless cantilena for a passionate call? I am not sure. In the assembly the two sexes are side by side; and 75 The Life of the Grasshopper you do not spend months on end in calling to some one who is at your elbow. Then again, I never see a female come rushing into the midst of the very noisiest orchestra. Sight is enough as a prelude to marriage here, for it is excellent; the wooer has no use for an everlasting declaration : the wooed is his next-door neighbour. Could it be a means then of charming, of touching the indifferent one? I still have my doubts. I notice no signs of satisfaction in the females; I do not see them give the least flutter nor sway from side to side, though the lovers clash their cymbals never so loudly. My neighbours the peasants say that, at harvest-time, the Cicada sings, '' Sego, sego, sego! Reap, reap, reap!" to encourage them to work. Whether harvesters of wheat or harvesters of thought, we follow the same occupation, one for the bread of the stomach, the other for the bread of the mind. I can understand their explanation, therefore; and I accept it as an instance of charming simplicity. Science asks for something better; but she finds in the insect a world that is closed to us. There is no possibility of divining or even 76 The Cicada: his Music suspecting the impression produced by the clash of the cymbals upon those who inspire it. All that I can say is that their impassive exterior seems to denote complete indiffer- ence. Let us not insist too much : the private feelings of animals are an unfathomable mystery. Another reason for doubt is this : those who are sensitive to music always have deli- cate hearing; and this hearing, a watchful sentinel, should give warning of any danger at the least sound. The birds, those skilled songsters, have an exquisitely fine sense of hearing. Should a leaf stir in the branches, should two wayfarers exchange a word, they will be suddenly silent, anxious, on their guard. How far the Cicada is from such sensibility! He has very clear sight. His large faceted eyes inform him of what happens on the right and what happens on the left; his three stemmata, like little ruby telescopes, explore the expanse above his head. The moment he sees us coming, he is silent and flies away. But place yourself behind the branch on which he Is singing, arrange so that you are not within reach of the five visual organs; and then talk, whistle, clap 17 The Life of the Grasshopper your hands, knock two stones together. For much less than this, a bird, though it would not see you, would interrupt its singing and fly away terrified. The imperturbable Cicada goes on rattling as though nothing were afoot. Of my experiments in this matter, I will mention only one, the most memorable. I borrow the municipal artillery, that is to say, the mortars which are made to thunder forth on the feast of the patron-saint. The gunner is delighted to load them for the benefit of the CIcadae and to come and fire them off at my place. There are two of them, crammed as though for the most sol- emn rejoicings. No politician making the circuit of his constituency in search of re- election was ever honoured with so m.uch powder. We are careful to leave the wind- ows open, to save the panes from break- ing. The two thundering engines are set at the foot of the plane-trees in front of my door. No precautions are taken to mask them: the Cicadae singing in the branches overhead cannot see what is happening below. We are an audience of six. We wait for a moment of comparative quiet. The num- 78 The Cicada: his Music ber of singers is checked by each of us, as are the depth and rhythm of the song. We are now ready, with ears pricked up to hear what will happen in the aerial orchestra. The mortar is let off, with a noise like a genuine thunder-clap. There is no excitement whatever up above. The number of executants is the same, the rhythm is the same, the volume of sound the same. The six witnesses are unanimous: the mighty explosion has in no way affected the song of the Cicadas. And the second mortar gives an exactly similar result. What conclusion are we to draw from this persistence of the orchestra, which is not at all surprised or put out by the firing of a gun? Am I to infer from it that the Cicada is deaf? I will certainly not venture so far as that; but, if any one else, more daring than I, were to make the assertion, I should really not know what arguments to employ in contradicting him. I should be obliged at least to concede that the Cicada is extremely hard of hearing and that we may apply to him the familiar saying, to bawl like a deaf man. When the Blue-winged Locust takes his luxurious fill of sunshine on a gravelly path 79 The Life of the Grasshopper and with his great hind-shanks rubs the rough edge of his wing-cases; when the Green Tree-frog, suffering from as chronic a cold as the Cacan, swells his throat among the leaves and distends it into a resounding bladder at the approach of a storm, are they both calling to their absent mates? By no means. The bow-strokes of the first produce hardly a perceptible strldulation; the throaty exuberance of the second is no more effective : the object of their desire does not come. Does the insect need these sonorous out- bursts, these loquacious avowals, to declare its flame? Consult the vast majority, whom the meeting of the two sexes leaves silent. I see in the Grasshopper's fiddle, the Tree- frog's bagpipes and the cymbals of the Cacan but so many methods of expressing the joy of living, the universal joy which every animal species celebrates after its kind. If any one were to tell me that the Cicadae strum on their noisy instruments without giv- ing a thought to the sound produced and for the sheer pleasure of feeling themselves alive, just as we rub our hands In a moment of satisfaction, I should not be greatly 80 The Cicada: his Music shocked. That there may be also a second- ary object in their concert, an object in which the dumb sex is interested, is quite possible, quite natural, though this has not yet been proved. 8i CHAPTER V THE CICADA: THE LAYING AND THE HATCHING OF THE EGGS THE Common Cicada entrusts her eggs to small dry branches. All those which Reaumur examined and found to be thus tenanted were derived from the mulberry- tree : a proof that the person commissioned to collect these eggs in the Avignon district was very conservative in his methods of search. In addition to the mulberry-tree, I, on the other hand, find them on the peach, the cherry, the willow, the Japanese privet and other trees. But these are exceptions. The Cicada really favours something dif- ferent. She wants, as far as possible, tiny stalks, which may be anything from the thickness of a straw to that of a lead-pencil, with a thin ring of wood and plenty of pith. So long as these conditions are fulfilled, the actual plant matters little. I should have to draw up a list of all the semiligneous flora 82 The Cicada: the Eggs of the district were I to try and catalogue the different supports used by the Cicada when laying her eggs. I shall content myself with naming a few of them in a note, to show the variety of sites of which she avails her- self.' The sprig occupied is never lying on the ground; it is in a position more or less akin to the perpendicular, most often in its na- tural place, sometimes detached, but in that case sticking upright by accident. Prefer- ence is given to a good long stretch of smooth, even stalk, capable of accommo- dating the entire laying. My best harvests are made on the sprigs of Spartiinn junceum, which are like straws crammed with pith, and especially on the tall stalks of Asphodelus cerasiferus, which rise for nearly three feet before spreading into branches. The rule is for the support, no matter what it is, to be dead and quite dry. Never- theless my notes record a few instances of * I have gathered the Cicada's eggs on Spartium junceum, or Spanish broom; on asphodel {Asphodelus cerasiferus) ; on Toad-flax {Linaria striata) ; on Cala- mintha nepeta, or lesser calamirit; on Hirschfeldia adpressa; on Chondrilla juncea, or common gum-succory; on garlic {Allium polyantfium) ; on Asteriscus spinosus and other plants. — Author's Note. 83 The Life of the Grasshopper eggs confided to stalks that are still alive, with green leaves and flowers in bloom. It is true that, in these highly exceptional cases, the stalk itself is of a pretty dry variety/ The work performed by the Cicada con- sists of a series of pricks such as might be made with a pin if it were driven downwards on a slant and made to tear the ligneous fibres and force them up slightly. Any one seeing these dots without knowing what pro- duced them would think first of some cryp- togamous vegetation, some Sphasriacea swelling and bursting its skin under the growth of its half-emerging perithecia. If the stalk be uneven, or if several Cicadae have been working one after the other at the same spot, the distribution of the punc- tures becomes confused and the eye is apt to wander among them, unable to perceive either the order in which they were made or the work of each individual. One char- acteristic is never missing, that is the slanting direction of the woody strip ploughed up, which shows that the Cicada always works in an upright position and drives her Imple- ^ Calaminiha nepeta, Hirschfeldia adpressa. — Author's Note. 84 The Cicada: the Eggs ment downwards into the twig, in a longi- tudinal direction. If the stalk be smooth and even and also of a suitable length, the punctures are nearly- equidistant and are not far from being in a straight line. Their number varies: it is small when the mother is disturbed in her operation and goes off to continue her laying elsewhere; it amounts to thirty or forty when the line of dots represents the total amount of eggs laid. The actual length of the row for the same number of thrusts like- wise varies. A few examples will enlighten us in this respect: a row of thirty measures 28 centimetres ^ on the toad-flax, 30 ^ on the gum-succory and only 12 ^ on the asphodel. Do not imagine that these variations in length have to do with the nature of the support: there are plenty of instances that prove the contrary; and the asphodel, which in one case shows us the punctures that are closest together, will in other cases show us those which are farthest removed. The di- stance between the dots depends on cir- cumstances which cannot be explained, but * 10.9 inches. — Translator's Note. ' 1 1.7 inches. — Translator's Note. * 4.6 inches. — Translator's Note. 85 The Life of the Grasshopper especially on the caprice of the mother, who concentrates her laying more at one spot and less at another according to her fancy. I have found the average measurement be- tween one hole and the next to be 8 to lo millimetres.^ Each of these abrasions is the entrance to a slanting cell, usually bored in the pithy por- tion of the stalk. This entrance is not closed, save by the bunch of ligneous fibres which are parted at the time of the laying but which come together again when the double saw of the ovipositor is withdrawn. At most, In certain cases, but not always, you see gleaming through the threads of this barri- cade a tiny glistening speck, looking like a glaze of dried albumen. This can be only an insignificant trace of some albuminous se- cretion which accompanies the eggs or else facilitates the play of the double boring-file. Just under the prick lies the cell, a very narrow passage which occupies almost the entire distance between its pin-hole and that of the preceding cell. Sometimes even there Is no partition separating the two; the upper floor runs Into the lower; and the eggs, though Inserted through several entrances, * .31 to .39 inch. — Translator's Note. 86 The Cicada: the Eggs are arranged In an uninterrupted row. Usu- ally, however, the cells are distinct. Their contents vary greatly. I count from six to fifteen eggs in each. The average is ten. As the number of cells of a complete laying is between thirty and forty, we see that the Cicada disposes of three to four hundred eggs. Reaumur arrived at the same figures from his examination of the ovaries. A fine family truly, capable by sheer num- bers of coping with very grave risks of de- struction. Yet I do not see that the adult Cicada is In greater danger than any other Insect: he has a vigilant eye, can get started quickly, Is a rapid flyer and inha- bits heights at which the cut-throats of the meadows are not to be feared. The Spar- row, It is true, is very fond of him. From time to time, after careful strategy, the ene- my swoops upon the plane-trees from the neighbouring roof and grabs the frenzied fiddler. A few pecks distributed right and left cut him up Into quarters, which form delicious morsels for the nestlings. But how often does not the bird return with an empty bag! The wary Cicada sees the attack coming, empties his bladder into his assail- ant's eyes and decamps. 87 The Life of the Grasshopper No, It Is not the Sparrow that makes it necessary for the Cicada to give birth to so numerous a progeny. The danger Hes else- where. We shall see how terrible It can be at hatching- and also at laylng-tlme. Two or three weeks after the emergence from the ground, that Is to say, about the middle of July, the Cicada busies herself with her eggs. In order to witness the lay- ing without trusting too much to luck, I had taken certain precautions which seemed to me to assure success. The Insect's favourite support Is the dry asphodel: I had learnt that from earlier observations. This plant Is also the one that lends Itself best to my plans, owing to Its long, smooth stalk. Now, during the first years of my residence here, I replaced the thistles In my enclosure by other native plants, of a less forbidding character. The asphodel Is among the new occupants and Is just what I want to-day. I therefore leave last year's dry stalks where they are; and, when the proper season comes, I inspect them dally. I have not long to wait. As early as the 15th of July, I find as many Cicadas as I could wish Installed on the asphodels, busily laying. The mother is always alone. Each The Cicada: the Eggs has a stalk to herself, without fear of any competition that might disturb the delicate process of inoculation. When the first occu- pant is gone, another may come, followed by others yet. There is ample room for all; but each in succession wishes to be alone. For the rest, there is no quarrelling among them; things happen most peacefully. If some mother appears and finds the place al- ready taken, she flies away so soon as she discovers her mistake and looks around else- where. The Cicada, when laying, always carries her head upwards, an attitude which, for that matter, she adopts in other circumstances. She lets you examine her quite closely, even under the magnifying-glass, so greatly ab- sorbed is she in her task. The ovipositor, which is about two-fifths of an inch long, is buried in the stalk, slantwise. So perfect Is the tool that the boring does not seem to call for very laborious operations. I see the mother give a jerk or two and dilate and contract the tip of her abdomen with fre- quent palpitations. That is all. The drill with Its double gimlets working alternately digs and disappears Into the wood, with a gentle and almost Imperceptible movement. 89 The Life of the Grasshopper Nothing particular happens during the lay- ing. The Insect is motionless. Ten minutes or so elapse between the first bite of the tool and the complete filling of the cell. The ovipositor Is then withdrawn with dehberate slowness, so as not to warp it. The boring-hole closes of Itself, as the lig- neous fibres come together again, and the Insect climbs a little higher, about as far as the length of its Instrument, in a straight line. Here we see a new punch of the gimlet and a new chamber receiving Its half-a-score of eggs. In this fashion the laying works Its way up from bottom to top. Once we know these facts, we are In a posi- tion to understand the remarkable arrange- ment controlling the work. The punctures, the entrances to the cells, are almost equidi- stant, because each time the Cicada ascends about the same height, roughly the length of her ovipositor. Very rapid In flight, she Is a very lazy walker. All that you ever see her do on the live branch on which she drinks is to move to a sunnier spot close by, with a grave and almost solemn step. On the dead branch where the eggs are laid she re- tains her leisurely habits, even exagger- ating them, in view of the Importance of 90 The Cicada: the Eggs the operation. She moves as httle as need be, shifting her place only just enough to avoid letting two adjoining cells encroach upon each other. The measure of the up- ward movement is provided approximately by the length of the bore. Also the holes are arranged in a straight line when their number is not great. Why indeed should the laying mother veer to the left or right on a stalk which has the same qualities all over? Loving the sun, she has selected the side of the stalk that Is most exposed to It. So long as she feels on her back a douche of heat, her supreme joy, she will take good care not to leave the situation which she considers so delightful for another upon which the sun's rays do not fall so directly. But the laying takes a long time when It is all performed on the same support. Allow- ing ten minutes to a cell, the series of forty which I have sometimes seen represents a period of six to seven hours. The sun there- fore can alter Its position considerably before the Cicada has finished her work. In that case the rectilinear direction becomes bent Into a spiral curve. The mother turns around her stalk as the sun Itself turns; and 91 The Life of the Grasshopper her row of pricks suggests the course of the gnomon's shadow on a cylindrical sundial. Very often, while the Cicada Is absorbed in her work of motherhood, an infinitesimal Gnat, herself the bearer of a boring-tool, labours to exterminate the eggs as fast as they are placed. Reaumur knew her. In nearly every bit of stick that he examined he found her grub, which caused him to make a mistake at the beginning of his researches. But he did not see, he could not see the im- pudent ravager at work. It is a Chalcidid some four to five millimetres ^ In length, all black, with knotty antennas, thickening a little towards their tips. The unsheathed boring- tool Is planted In the under part of the ab- domen, near the middle, and sticks out at right angles to the body, as In the case of the Leucospes,^ the scourge of certain mem- bers of the Bee-tribe. Having neglected to capture the Insect, I do not know what name the nomenclators have bestowed upon It, If indeed the dwarf that exterminates Clcadae has been catalogued at all. What I do know something about is its *.i56 to .195 inch. — Translator's Note. ' Cf. The Mason-bees, by J. Henri Fabre, translated by Alexander Teixeira de Mattos: chap. xi. — Translator's Note. 92 The Cicada: the Eggs calm temerity, its brazen audacity in the im- mediate presence of the colossus who could crush it by simply stepping on it. I have seen as many as three exploiting the unhappy mother at the same time. They keep close behind each other, either working their probes or awaiting the propitious moment. The Cicada has just stocked a cell and is climbing a little higher to bore the next. One of the brigands runs to the abandoned spot; and here, almost under the claws of the giantess, without the least fear, as though she were at home and accomplishing a meri- torious act, she unsheathes her probe and In- serts it into the column of eggs, not through the hole already made, which bristles with broken fibres, but through some lateral crevice. The tool works slowly, because of the resistance of the wood, which is almost Intact. The Cicada has time to stock the next floor above. As soon as she has finished, a Gnat stand- ing immediately behind her, waiting to per- form her task, takes her place and comes and Introduces her own exterminating germ. By the time that the mother has exhausted her ovaries and flies avv^ay, most of her cells have, in this fashion, received the alien egg which 93 The Life of the Grasshopper will be the ruin of their contents. A small, quick-hatching grub, one only to each chamber, generously fed on a round dozen raw eggs, will take the place of the Cicada's family. O deplorable mother, have centuries of experience taught you nothing? Surely, with those excellent eyes of yours, you cannot fail to see the terrible sappers, when they flutter around you, preparing their felon stroke ! You see them, you know that they are at your heels; and you remain impassive and let yourself be victimized. Turn round, you easy-going colossus, and crush the pigmies ! But you will do nothing of the sort: you are incapable of altering your instincts, even to lighten your share of maternal sorrow. The Common Cicada's eggs are of a gleaming ivory-white. Elongated in shape and conical at both ends, they might be com- pared with miniature weavers'-shuttles. They are two millimetres and a half long by half a millimetre wide.^ They are ar- ranged in a row, slightly overlapping. The Ash Cicada's, which are a trifle smaller, are packed in regular parcels mimicking mi- croscopic bundles of cigars. We will devote * About iV X ^ inch. — Translator's Note. 94 The Cicada: the Eggs our attention exclusively to the first; their story will tell us that of the others. September is not over before the gleaming ivory-white gives place to straw-colour. In the early days of October there appear, In the front part, two little dark-brown spots, round and clearly-defined, which are the ocular specks of the tiny creature In course of formation. These two shining eyes, which almost look at you, combined with the cone- shaped fore-end, give the eggs an appearance of finless fishes, the very tiniest of fishes, for which a walnut-shell would make a suitable bowl. About the same period, I often see on my asphodels and those on the hills around indi- cations of a recent hatching. These indica- tions take the form of certain discarded clothes, certain rags left on the threshold by the new-born grubs moving their quarters and eager to reach a new lodging. We shall learn In an Instant what these cast skins mean. Nevertheless, In spite of my visits, which were assiduous enough to deserve a better result, I have never succeeded In seeing the young Clcadse come out of their cells. My home breeding prospers no better. For two 95 The Life of the Grasshopper years running, at the right time, I collect in boxes, tubes and jars a hundred twigs of all sorts colonized with Cicada-eggs; not one of them shows me what I am so anxious to see, the emergence of the budding Cicadas. Reaumur experienced the same disappoint- ment. He tells us how all the eggs sent by his friends proved failures, even when he carried them in a glass tube in his fob to give them a mild temperature. O my revered master, neither the warm shelter of our studies nor the niggardly heating-apparatus of our breeches is enough in this case ! What is needed is that supreme stimulant, the kisses of the sun; what is needed, after the morning coolness, which already is sharp enough to make us shiver, is the sudden glow of a glorious autumn day, summer's last farewell. It was in such circumstances as these, when a bright sun supplied a violent con- trast to a cold night, that I used to find signs of hatching; but I always came too late : the young Cicadae were gone. At most I some- times happened to find one hanging by a thread from his native stalk and struggling in mid-air. I thought him caught in some shred of cobweb. 96 The Cicada: the Eggs At last, on the 27th of October, despairing of success, I gathered the asphodels in the enclosure and, taking the armful of dry stalks on which the Cicada had laid, carried it up to my study. Before abandoning all hope, I proposed once more to examine the cells and their contents. It was a cold morn- ing. The first fire of the season had been lit. I put my little bundle on a chair in front the hearth, without any intention of try- ing the effect of the hot flames upon the nests. The sticks which I meant to split open one by one were within easier reach of my hand there. That was the only con- sideration which made me choose that par- ticular spot. Well, while I was passing my magnifying- glass over a split stem, the hatching which I no longer hoped to see suddenly took place beside me. My bundle became alive ; the young larvae emerged from their cells by the dozen. Their number was so great that my professional instincts were amply satisfied. The eggs were exactly ripe; and the blaze on the hearth, bright and penetrating, produced the same effect as sunlight out of doors. I lost no time in profiting by this unexpected stroke of luck. 97 The Life of the Grasshopper At the aperture of the egg-chamber, among the torn fibres, a tiny cone-shaped body appears, with two large black eye-spots. To look at, it is absolutely the fore-part of the egg, which, as I have said, resembles the front of a very minute fish. One would think that the egg had changed its position, climb- ing from the bottom of the basin to the orifice of the little passage. But an egg to move! A germ to start walking! Such a thing was impossible, had never been known; I must be suffering from an illusion. I split open the stalk; and the mystery is revealed. The real eggs, though a little disarranged, have not changed their position. They are empty, reduced to transparent bags, torn considerably at their fore-ends. From them has issued the very singular organ- ism whose salient characteristics I will now set forth. In its general shape, the configuration of the head and the large black eyes, the crea- ture, even more than the egg, presents the appearance of an extremely small fish. A mock ventral fin accentuates the likeness. This sort of oar comes from the fore-legs, which, cased in a special sheath, lie back- wards, stretched against each other in a 98 The Cicada: the Eggs straight line. Its feeble power of move' ment must help the grub to come out of the egg-shell and — a more difficult matter — out of the fibrous passage. Withdrawing a little way from the body and then returning, this lever provides a purchase for progression by means of the terminal claws, which are al- ready well-developed. The four other legs are still wrapped in the common envelope and are absolutely inert. This applies also to the antennae, which can hardly be per- ceived through the lens. Altogether, the organism newly issued from the egg is an exceedingly small, boat-shaped body, with a single oar pointing backwards on the ventral surface and formed of the two fore-legs joined together. The segmentation is very clearly marked, especially on the abdomen. Lastly, the whole thing Is quite smooth, with not a hair on it. What name shall I give to this Initial state of the Cicada, a state so strange and unfore- seen and hitherto unsuspected? Must I knock Greek words together and fashion some uncouth expression? I shall do nothing of the sort, convinced as I am that barbarous terms are only a cumbrous Impediment to science. I shall simply call it " the primary 99 The Life of the Grasshopper larva," as I did in the case of the Oil-beetles, the Leucospes and the Anthrax/ The form of the primary larva In the Cicadse is eminently well-suited for the emer- gence. The passage in which the egg is hatched is very narrow and leaves just room for one to go out. Besides, the eggs are ar- ranged in a row, not end to end, but partly overlapping. The creature coming from the farther ranks has to make its way through the remains of the eggs already hatched in front of it. To the narrowness of the cor- ridor is added the block caused by the empty shells. In these conditions, the larva in the form which it will have presently, when it has torn Its temporary scabbard, would not be able to clear the difficult pass. Irksome antennae, long legs spreading far from the axis of the body, picks with curved and pointed ends that catch on the road : all these are in the way of a speedy deliverance. The eggs in one cell hatch almost simultaneously. It Is ne- cessary that the new-born grubs In front should move out as fast as they can and make * Cf. The Life of the Fly, by J. Henri Fabre, translated by Alexander Teixeira de Mattos: chaps, ii, iii and v. — Translator's Note. 100 The Cicada: the Eggs room for those behind. This necessitates the smooth, boatlike form, devoid of all pro- jections, which makes its way insinuatingly, like a wedge. The primary larva, with its different appendages closely fixed to Its body inside a common sheath, with Its boat shape and its single oar possessing a certain power of movement, has its part to play : its business is to emerge into daylight through a difficult passage. Its task is soon done. Here comes one of the emigrants, showing its head with the great eyes and lifting the broken fibres of the aperture. It works Its way farther and far- ther out, with a progressive movement so slow that the lens does not easily perceive it. In half an hour at soonest, the boat-shaped object appears entirely; but it is still caught by its hinder end in the exit-hole. The emergence-jacket splits without fur- ther delay; and the creature sheds its skin from front to back. It is now the normal larva, the only one that Reaumur knew. The cast slough forms a suspensory thread, ex- panding Into a little cup at its free end. In this cup is contained the tip of the abdomen of the larva, which, before dropping to the ground, treats itself to a sun-bath, hardens lOI The Life of the Grasshopper itself, kicks about and tries its strength, swinging indolently at the end of its life- line. This " little Flea," as Reaumur calls It, first white, then amber, is at all points the larva that will dig into the ground. The antennae, of fair length, are free and wave about; the legs work their joints; those in front open and shut their claws, which are the strongest part of them. I know hardly any more curious sight than that of this miniature gymnast hanging by Its hinder- part, swinging at the least breath of wind and making ready in the air for its somersault into the world. The period of suspension varies. Some larvae let themselves drop in half an hour or so; others remain for hours in their long-stemmed cup; and some even wait until the next day. Whether quick or slow, the creature's fall leaves the cord, the slough of the primary larva, swinging. When the whole brood has disappeared, the orifice of the cell is thus hung with a cluster of short, fine threads, twisted and rumpled, like dried white of egg. Each opens Into a little cup at Its free end. They are very delicate and ephemeral relics, which you cannot touch without de- 102 The Cicada: the Eggs stroying them. The sHghtest wind soon blows them away. Let us return to the larva. Sooner or later, without losing much time, It drops to the ground, either by accident or of its own accord. The infinitesimal creature, no bigger than a Flea, has saved Its tender, bud- ding flesh from the rough earth by swinging on its cord. It has hardened itself in the air, that luxurious eiderdown. It now plunges into the stern realities of life. I see a thousand dangers ahead of It. The merest breath of wind can blow the atom here, on the Impenetrable rock, or there, on the ocean of a rut where a little water stagnates, or elsewhere, on the sand, the starvation region where nothing grows, or again on a clay soil, too tough for dig- ging. These fatal expanses are frequent; and so are the gusts that blow one away in this windy season which has already set in unpleasantly by the end of October. The feeble creature needs very soft soil, easily entered, so as to obtain shelter Im- mediately. The cold days are drawing nigh; the frosts are coming. To wander about on the surface of the ground for any length of time would expose us to grave dangers. We 103 The Life of the Grasshopper had better descend into the earth without delay; and that to a good depth. This one imperative condition of safety is in many cases impossible to realize. What can little Flea's-claws do against rock, flint or hard- ened clay? The tiny creature must perish unless it can find an underground refuge in time. The first establishment, which is exposed to so many evil chances, is, so everything shows us, a cause of great mortality in the Cicada's family. Already the little black parasite, the destroyer of the eggs, has told us how expedient it is for the mothers to ac- complish a long and fertile laying; the diffi- culties attendant upon the initial installation In their turn explain why the maintenance of the race at Its suitable strength requires three or four hundred eggs to be laid by each of them. Subject to excessive spoliation, the Cicada Is fertile to excess. She averts by the richness of her ovaries the multitude of dangers threatening her. In the experiment which it remains for me to make, I will at least spare the larva the difficulties of the first Installation. I se- lect some very soft, very black heath-mould and pass it through a fine sieve. Its dark 104 The Cicada: the Eggs colour will enable me more easily to find the little yellow creature when I want to see what is happening; and its softness will suit the feeble mattock. I heap it not too tightly in a glas::; pot; I plant a little tuft of thyme in it; I sow a few grains of wheat. There is no hole at the bottom of the pot, though there ought to be, if the thyme and the wheat are to thrive; the captives, however, finding the hole, would be certain to escape through it. The plantation will suffer from this lack of drainage; but at least I am certain of finding my animals with the aid of my mag- nlfylng-glass and plenty of patience. Be- sides, I shall indulge in no excesses in the matter of Irrigation, supplying only enough water to prevent the plants from dying. When everything Is ready and the corn is beginning to put forth Its first shoots, I place six young Cicada-larvae on the surface of the soil. The puny grubs run about and explore the earthy bed pretty nimbly; some make unsuccessful attempts to climb the side of the pot. Not one seems Inclined to bury Itself, so much so that I anxiously wonder what the object can be of these active and prolonged Investigations. Two hours pass and the rest- less roaming never ceases. 105 The Life of the Grasshopper What is it that they want ? Food ? I offer them some httle bulbs with bundles of sprout- ing roots, a few bits of leaves and some fresh blades of grass. Nothing tempts them nor induces them to stand still. They appear to be selecting a favourable spot before de- scending underground. These hesitating ex- plorations are superfluous on the soil which I have industriously prepared for them: the whole surface, so it seems to me, lends it- self capitally to the work which I expect to see them accomplish. Apparently it is not enough. Under natural conditions, a preliminary run round may well be indispensable. There, sites as soft as my bed of heath-mould, purged of all hard bodies and finely sifted, are rare. There, on the other hand, coarse soils, on which the microscopic mattock can make no impression, are frequent. The grub has to roam at random, to walk about for some time before finding a suitable place. No doubt many even die, exhausted by their fruitless search. A journey of exploration, in a country a few inches across, forms part, therefore, of the young Cicada's curriculum. In my glass jar, so sumptuously furnished, the pilgrimage is uncalled for. No matter: io6 The Cicada: the Eggs it has to be performed according to the time- honoured rites. My gadabouts at last grow calm. I see them attack the earth with the hooked mat- tocks of their fore-feet, digging into it and making the sort of excavation which the point of a thick needle would produce. Armed with a magnifying-glass, I watch them wielding their pick-axes, watch them raking an atom of earth to the surface. In a few minutes a well has been scooped out. The little creature goes down it, buries itself and is henceforth invisible. Next day I turn out the contents of the pot, without breaking the clod held together by the roots of the thyme and the wheat. I find all my larvae at the bottom, stopped from going farther by the glass. In twenty- four hours they have traversed the entire thickness of the layer of earth, about four inches. They would have gone even lower but for the obstacle at the bottom. On their way they probably came across my thyme- and wheat-roots. Did they stop to take a little nourishment by driving in their suckers? It is hardly probable. A few of these rootlets are trailing at the bottom of the empty pot. Not one of my 107 The Life of the Grasshopper six prisoners is installed on them. Perhaps in overturning the glass I have shaken them off. It is clear that underground there can be no other food for them than the juice of the roots. Whether full-grown or in the larval stage, the Cicada lives on vegetables. As an adult, he drinks the sap of the branches; as a larva, he sucks the sap of the roots. But at what moment is the first sip taken? This I do not yet know. What goes before seems to tell us that the newly- hatched grub is in a greater hurry to reach the depths of the soil, sheltered from the coming colds of winter, than to loiter at the drinking-bars encountered on the way. I put back the clod of heath-mould and for the second time place the six exhumed larvae on the surface of the soil. Wells are dug without delay. The grubs disappear down them. Finally I put the pot in my study-window, where it will receive all the influences of the outer air, good and bad alike. A month later, at the end of November, I make a second inspection. The young Cicadae are crouching, each by itself, at the bottom of the clod of earth. They are not io8 The Cicada: the i/ggs clinging to the roots; they have not altered in appearance or in size. I find them now just as I saw them at the beginning of the experiment, only a little less active. Does not this absence of growth during the in- terval of November, the mildest month of winter, seem to show that no nourishment is taken throughout the cold season? The young Sitaris-beetles,^ those other animated atoms, as soon as they issue from the egg at the entrance to the Anthophora's " galleries, remain in motionless heaps and spend the winter in complete abstinence. The little Cicadae would appear to behave in much the same manner. Once buried in depths where there is no fear of frosts, they sleep, solitary, in their winter-quarters and await the return of spring before broaching some root near by and taking their first re- freshment. I have tried, but without success, to con- firm by actual observation the inferences to be drawn from the above results. In the spring, in April, for the third time I unpot my plantation. I break up the clod and * Cf. T/ie Life of the Fly: chap. iv. — Translator's Note. ^ Cf. Bramhle-bees and Others, by J. Henri Fabre, translated by Alexander Teixeira de Mattos: passim. — Translator's Note. 109 The Life of the Grasshopper scrutinize it under the magnifying-glass. I feel as if I were looking for a needle in a haystack. At last I find my little Cicadae. They are dead, perhaps of cold, notwith- standing the bell-glass with which I had cov- ered the pot; perhaps of starvation, if the thyme did not suit them. The problem is too difficult to solve ; I give it up. To succeed in this attempt at rearing one would need a very wide and deep bed of earth, providing a shelter from the rigours of winter, and, because I do not know which are the insect's favourite roots, there would also have to be a varied vegetation. In which the little larvae could choose according to their tastes. These conditions are quite practicable; but how is one afterwards to find in that huge mass of earth, measuring a cubic yard at least, the atom which I have so much trouble In distinguishing In a handful of black mould? And, besides, such consci- entious digging would certainly detach the tiny creature from the root that nourishes It. The underground life of the early Cicada remains a secret. That of the well-developed larva Is no better-known. When digging in the fields, if you turn up the soil to any depth, you are constantly finding the fierce no The Cicada: the Eggs little burrower under your spade ; but to find it fastened to the roots from whose sap it undoubtedly derives its nourishment is quite another matter. The upheaval occasioned by the spade warns it of its danger. It releases its sucker and retreats to some gallery; and, when discovered, it is no longer drinking. If agricultural digging, with its inevitable disturbances, is unable to tell us anything of the grub's underground habits, it does at least inform us how long the larval stage lasts. Some obliging husbandmen, breaking up their land, in March, rather deeper than usual, were so very good as to pick up for me all the larvae, big and small, unearthed by their labour. The harvest amounted to several hundreds. Marked differences In bulk divided the total into three classes : the large ones, with rudiments of wings similar to those possessed by the larvae leaving the ground, the medium-sized and the small. Each of these classes must correspond with a different age. We will add to them the larvae of the last hatching, microscopic crea- tures that necessarily escaped the eyes of my rustic collaborators; and we arrive at four years as the probable duration of the underground life of the Cicadae. Ill The Life of the Grasshopper Their existence in the air is more easily- calculated. I hear the first Cicadae at the approach of the summer solstice. The orchestra attains its full strength a month later. A few laggards, very few and very far between, continue to execute their faint solos until the middle of September. That IS the end of the concert. As they do not all come out of the ground at the same period. It is obvious that the singers of Sep- tember are not contemporary v/Ith those of June. If we strike an average between these two extreme dates, we shall have about five weeks. Four years of hard work underground and a month of revelry In the sun : this then represents the Cicada's life. Let us no longer blame the adult for his delirious tri- umph. For four years, in the darkness, he has worn a dirty parchment smock; for four years he has dug the earth with his mattocks; and behold the mud-stained navvy suddenly attired in exquisite raiment, possessed of wings that rival the bird's, drunk with the heat and inundated with light, the supreme joy of this world ! What cymbals could ever be loud enough to celebrate such felicity, so richly earned and so ephemeral! 112 CHAPTER VI THE MANTIS: HER HUNTING ANOTHER creature of the south, at least -as interesting as the Cicada, but much less famous, because it makes no noise. Had Heaven granted it a pair of cymbals, the one thing needed, its renown would eclipse the great musician's, for it is most unusual in both shape and habits. Folk hereabouts call it lou Prego-DieUy the animal that prays to God. Its official name is the Praying Mantis (M. religiosa, LiN.). The language of science and the peasant's artless vocabulary agree in this case and represent the queer creature as a pythoness delivering her oracles or an ascetic rapt in pious ecstasy. The comparison dates a long way back. Even in the time of the Greeks the insect was called Mavn?, the divine, the prophet. The tiller of the soil is not par- ticular about analogies : where points of re- semblance are not too clear, he will make 113 The Life of the Grasshopper up for their deficiencies. He saw on the sun- scorched herbage an Insect of imposing ap- pearance, drawn up majestically In a half- erect posture. He noticed Its gossamer wings, broad and green, trailing like long veils of finest lawn; he saw Its fore-legs, its arms so to speak, raised to the sky in a gest- ure of Invocation. That was enough; popu- lar Imagination did the rest; and behold the bushes from ancient times stocked with Delphic priestesses, with nuns In orison. Good people, with your childish simplicity, how great was your mistake ! Those sancti- monious airs are a mask for Satanic habits; those arms folded In prayer are cut-throat weapons : they tell no beads, they slay what- ever passes within range. Forming an ex- ception which one would never have sus- pected in the herbivorous order of the Orthoptera, the Mantis feeds exclusively on living prey. She is the tigress of the peace- able entomological tribes, the ogress in am- bush who levies a tribute of fresh meat. Picture her with sufficient strength; and her carnivorous appetites, combined with her traps of horrible perfection, would make her the terror of the country-side. The Prego- Dieu would become a devilish vampire. 114 The Mantis: her Hunting Apart from her lethal implement, the Mantis has nothing to inspire dread. She is not without a certain beauty, in fact, with her slender figure, her elegant bust, her pale- green colouring and her long gauze wings. No ferocious mandibles, opening like shears; on the contrary, a dainty pointed muzzle that seems made for billing and cooing. Thanks to a flexible neck, quite independent of the thorax, the head is able to move freely, to turn to right or left, to bend, to lift itself. Alone among insects, the Mantis directs her gaze; she inspects and examines; she almost has a physiognomy. Great indeed is the contrast between the body as a whole, with its very pacific aspect, and the murderous mechanism of the fore- legs, which are correctly described as rap- torial. The haunch is uncommonly long and powerful. Its function is to throw forward the rat-trap, which does not await its victim but goes in search of it. The snare is decked out with some show of finery. The base of the haunch is adorned on the inner surface with a pretty, black mark, having a white spot in the middle; and a few rows of bead- like dots complete the ornamentation. The thigh, longer still, a sort of flat- us The Life of the Grasshopper tened spindle, carries on the front half of its lower surface two rows of sharp spikes. In the inner row there are a dozen, alternately black and green, the green being shorter than the black. This alterna- tion of unequal lengths increases the number of cogs and improves rhe effectiveness of the weapon. The outer row is simpler and has only four teeth. Lastly, three spurs, the longest of all, stand out behind the two rows. In short, the thigh is a saw with two parallel blades, separated by a groove in which the leg lies when folded back. The leg, which moves very easily on its joint with the thigh, is likewise a double- edged saw. The teeth are smaller, more numerous and closer together than those on the thigh. It ends in a strong hook whose point vies with the finest needle for sharp- ness, a hook fluted underneath and having a double blade like a curved pruning-knife. This hook, a most perfect instrument for piercing and tearing, has left me many a pain- ful memory. How often, when Mantis- hunting, clawed by the insect which I had just caught and not having both hands at liberty, have I been obliged to ask somebody else to release me from my tenacious cap- ii6 The Mantis: her Hunting tive ! To try to free yourself by force, with- out first disengaging the claws implanted in your flesh, would expose you to scratches similar to those produced by the thorns of a rose-tree. None of our insects is so troublesome to handle. The Mantis clav/s you with her pruning-hooks, pricks you with her spikes, seizes you in her vice and makes self-defence almost impossible If, wishing to keep your prize alive, you refrain from giving the pinch of the thumb that v/ould put an end to the struggle by crushing the creature. When at rest, the trap is folded and pressed back against the chest and looks quite harmless. There you have the insect praying. But, should a victim pass, the atti- tude of prayer is dropped abruptly. Sud- denly unfolded, the three long sections of the machine throw to a distance their term- inal grapnel, which harpoons the prey and, in returning, draws it back between the two saw^s. The vice closes with a movement like that of the fore-arm and the upper arm; and all Is over: Locusts, Grasshoppers and others even more powerful, once caught In the mechanism with Its four rows of teeth, are irretrievably lost. Neither their desperate 117 The Life of the Grasshopper fluttering nor their kicking will make the ter- rible engine release its hold. An uninterrupted study of the Mantis' habits is not practicable in the open fields; we must rear her at home. There is no difficulty about this: she does not mind being interned under glass, on condition that she be well fed. Offer her choice viands, served up fresh daily, and she will hardly feel her absence from the bushes. As cages for my captives I have some ten large wire-gauze dish-covers, the same that are used to protect meat from the Flies. Each stands in a pan filled with sand. A dry tuft of thyme and a flat stone on which the laying may be done later constitute all the furniture. These huts are placed in a row on the large table in my insect laboratory, where the sun shines on them for the best part of the day. I instal my captives in them, some singly, some in groups. It is in the second fortnight of August that I begin to come upon the adult Mantis in the withered grass and on the brambles by the road-side. The females, already notably corpulent, are more frequent from day to day. Their slender companions, on the other hand, are rather scarce; and I some- ii8 The Mantis: her Hunting times have a good deal of difficulty in making up my couples, for there is an appalling con- sumption of these dwarfs in the cages. Let us keep these atrocities for later and speak first of the females. They are great eaters, whose maintenance, when it has to last for some months, is none too easy. The provisions, which are nibbled at disdainfully and nearly all wasted, have to be renewed almost every day. I trust that the Mantis is more economical on her native bushes. When game is not plentiful, no doubt she devours every atom of her catch; in my cages she is extravagant, often drop- ping and abandoning the rich morsel after a few mouthfuls, without deriving any fur- ther benefit from it. This appears to be her particular method of beguiling the tedium of captivity. To cope with these extravagant ways I have to employ assistants. Two or three small local idlers, bribed by the promise of a slice of melon or bread-and-butter, go morning and evening to the grass-plots in the neighbourhood and fill their game-bags — cases made of reed-stumps — with live Lo- custs and Grasshoppers. I on my side, net in hand, make a daily circuit of my enclosure, 119 The Life of the Grasshopper in the hope of obtaining some choice morsel for my boarders. These tit-bits are Intended to show me to what lengths the Mantis' strength and dar- ing can go. They Include the big Grey Locust {Pachytylus cinerescens, Fab.), who is larger than the insect that will consume him; the White-faced Decticus, armed with a vigorous pair of mandibles whereof our fin- gers would do well to fight shy; the quaint Tryxalis, who wears a pyramid-shaped mitre on her head; the Vine Ephippiger,^ who clashes cymbals and sports a sword at the bottom of her pot-belly. To this assortment of game that Is not any too easy to tackle, let us add two monsters, two of the largest Spiders of the district: the Silky Epeira, whose flat, festooned abdomen Is the size of a franc piece; and the Cross Spider, or Dia- dem Epeira," who is hideously hairy and obese. I cannot doubt that the Mantis attacks such adversaries In the open, when I see her. * The Decticus, Trysails and Ephippig:er are all species of Grasshoppers or Locusts. — Translator's Note. ^ Epeira sericea and E. diaJcma are two Garden Spiders for whom cf. T/ie Life of the Spider, by J. Henri Fabre, translated by Alexander Teixeira de Mattes: chaps. ix to xiv. — Translator's Note. 120 The Mantis: her Hunting under my covers, boldly giving battle to whatever comes in sight. Lying in wait among the bushes, she must profit by the fat prizes offered by chance even as, in the wire cage, she profits by the treasures due to my generosity. Those big hunts, full of danger, are no new thing; they form part of her normal existence. Nevertheless they appear to be rare, for want of opportunity, perhaps to the Mantis' deep regret. Locusts of all kinds. Butterflies, Dragon- flies, large Flies, Bees and other moderate- sized captures are what we usually find in the lethal limbs. Still the fact remains that, in my cages, the daring huntress recoils be- fore nothing. Sooner or later. Grey Locust and Decticus, Epeira and Tryxalis are har- pooned, held tight betw^een the saws and crunched v/ith gusto. The facts are worth describing. At the sight of the Grey Locust who has heedlessly approached along the trelllswork of the cover, the Mantis gives a convulsive shiver and suddenly adopts a terrifying pos- ture. An electric shock would not produce a more rapid effect. The transition is so abrupt, the attitude so threatening that the observer beholding it for the first time at 121 The Life of the Grasshopper once hesitates and draws back his fingers, ap- prehensive of some unknown danger. Old hand as I am, I cannot even now help being startled, should I happen to be thinking of something else. You see before you, most unexpectedly, a sort of bogey-man or Jack-in-the-box. The wing-covers open and are turned back on either side, slantingly; the wings spread to their full extent and stand erect like parallel sails or like a huge heraldic crest towering over the back; the tip of the abdomen curls upwards like a crosier, rises and falls, relax- ing with short jerks and a sort of sough, a *'Whoof! Whoof!" like that of a Turkey- cock spreading his tall. It reminds one of the puffing of a startled Adder. Planted defiantly on its four hind-legs, the Insect holds its long bust almost upright. The murderous legs, originally folded and pressed together upon the chest, open wide, forming a cross with the body and revealing the arm-pits decorated with rows of beads and a black spot with a white dot In the centre. These two faint imitations of the eyes in a Peacock's tall, together with the dainty Ivory beads, are warlike ornaments kept hidden at ordinary times. They are 122 The Mantis: her Hunting taken from the jewel-case only at the moment when we have to make ourselves brave and terrible for battle. Motionless in her strange posture, the Mantis watches the Locust, with her eyes fixed in his direction and her head turning as on a pivot whenever the other changes his place. The object of this attitudinizing is evident : the Mantis wants to strike terror into her dangerous quarry, to paralyze it with fright, for, unless demoralized by fear, it would prove too formidable. Does she succeed in this? Under the shiny head of the Decticus, behind the long face of the Locust, who can tell what passes? No sign of excitement betrays itself to our eyes on those impassive masks. Neverthe- less it is certain that the threatened one is aware of the danger. He sees standing be- fore him a spectre, with uplifted claws, ready to fall upon him; he feels that he is face to face with death; and he fails to escape while there is yet time. He who excels in leaping and could so easily hop out of reach of those talons, he, the big-thighed jumper, remains stupidly where he is, or even draws nearer with a leisurely step. They say that little birds, paralysed with 123 The Life of the Grasshopper terror before the open jaws of the Snake, spell-bound by the reptile's gaze, lose their power of flight and allow themselves to be snapped up. The Locust often behaves In much the same way. See him within reach of the enchantress. The two grapnels fall, the claws strike, the double saws close and clutch. In vain the poor wretch protests: he chews space with his m.andibles and, kick- ing desperately, strikes nothing but the air. His fate is sealed. The Mantis furls her wings, her battle-standard; she resumes her normal posture; and the meal begins. In attacking the Tryxalis and the Ephip- piger, less dangerous game than the Grey Locust and the Decticus, the spectral attitude Is less Imposing and of shorter duration. Often the throw of the grapnels Is sufficient. This is likewise so in the case of the Epeira, who Is grasped round the body with not a thought of her poison-fangs. With the smaller Locusts, the usual fare In my cages as in the open fields, the Mantis seldom em- ploys her intimidation-methods and contents herself with seizing the reckless one that passes within her reach. When the prey to be captured Is able to offer serious resistance, the Mantis has at 124 The Mantis: her Hunting her service a pose that terrorizes and fas- cinates her quarry and gives her claws a means of hitting with certainty. Her rat- traps close on a demoralized victim incapa- ble of defence. She frightens her victim into immobility by suddenly striking a spectral attitude. The wings play a great part in this fan- tastic pose. They are very wide, green on the outer edge, colourless and transparent every elsewhere. They are crossed length- wise by numerous veins, which spread in the shape of a fan. Other veins, transversal and finer, intersect the first at right angles and with them form a multitude of meshes. In the spectral attitude, the v/ings are displayed and stand upright in two parallel planes that almost touch each other, like the wings of a Butterfly at rest. Between them the curled tip of the abdomen moves with sudden starts. The sort of breath which I have compared with the pufling of an Adder in a posture of defence comes from this rubbing of the ab- domen against the nerves of the wings. To imitate the strange sound, all that you need do is to pass your nail quickly over the upper surface of an unfurled wing. Wings are essential to the male, a slender 125 The Life of the Grasshopper pigmy who has to wander from thicket to thicket at mating-tlme. He has a well- developed pair, more than sufficient for his flight, the greatest range of which hardly amounts to four or five of our paces. The little fellow is exceedingly sober in his appe- tites. On rare occasions, in my cages, I catch him eating a lean Locust, an insig- nificant, perfectly harmless creature. This means that he knows nothing of the spectral attitude, which is of no use to an unambi- tious hunter of his kind. On the other hand, the advantage of the wings to the female is not very obvious, for she is inordinately stout at the time when her eggs ripen. She climbs, she runs; but, weighed down by her corpulence, she never flies. Then what is the object of wings, of wings, too, which are seldom matched for breadth? The question becomes more significant if we consider the Grey Mantis {Ameles de- color)^ who is closely akin to the Praying Mantis. The male is winged and Is even pretty quick at flying. The female, who drags a great belly full of eggs, reduces her wings to stumps and, like the cheese-makers of Auvergne and Savoy, wears a short-tailed 126 The Mantis: her Hunting jacket. For one who is not meant to leave the dry grass and the stones, this ab- breviated costume is more suitable than superfluous gauze furbelows. The Grey Mantis is right to retain but a mere vestige of the cumbrous sails. Is the other wrong to keep her wings, to exaggerate them, even though she never flies? Not at all. The Praying Mantis hunts big game. Sometimes a formidable prey appears in her hiding-place. A direct attack might be fatal. The thing to do is first to intimidate the new-comer, to conquer his resistance by terror. With this object she suddenly unfurls her wings into a ghost's winding-sheet. The huge sails incapable of flight are hunting-implements. This strata- gem is not needed by the little Grey Mantis, who captures feeble prey, such as Gnats and new-born Locusts. The two huntresses, who have similar habits and, because of their stoutness, are neither of them able to fly, are dressed to suit the difficulties of the ambus- cade. The first, an impetuous amazon, pui^s her wings into a threatening standard; the second, a modest fowler, reduces them to a pair of scanty coat-tails. In a fit of hunger, after a fast of some 127 The Life of the Grasshopper days' duration, the Praying Mantis will gob- ble up a Grey Locust whole, except for the wings, which are too dry; and yet the victim of her voracity Is as big as herself, or even bigger. Two hours are enough for con- suming this monstrous head of game. An orgy of the sort Is rare. I have witnessed It once or twice and have always wondered how the gluttonous creature found room for so much food and how It reversed In Its favour the axiom that the cask must be greater than Its contents. I can but admire the lofty privileges of a stomach through which matter merely passes, being at once digested, dissolved and done away with. The usual bill of fare In my cages con- sists of Locusts of greatly varied species and sizes. It is Interesting to watch the Mantis nibbling her Acrldian, firmly held in the grip of her two murderous fore-legs. Not- withstanding the fine, pointed muzzle, which seems scarcely made for this gorging, the whole dish disappears, with the excep- tion of the wings, of which only the slightly fleshy base Is consumed. The legs, the tough skin, everything goes down. Sometimes the Mantis seizes one of the big hinder thighs by the knuckle-end, lifts it to her mouth, 128 The Mantis: her Flunting tastes it and crunches it with a Httle air of satisfaction. The Locust's fat and juicy thigh may well be a choice morsel for her, even as a leg of mutton is for us. The prey is first attacked in the neck. While one of the two lethal legs holds the victim transfixed through the middle of the body, the other presses the head and makes the neck open upwards. The Mantis' muzzle roots and nibbles at this weak point in the armour with some persistency. A large wound appears in the head. The Locust gradually ceases kicking and becomes a life- less corpse; and, from this moment, freer in its movements, the carnivorous insect picks and chooses its morsel. This preliminary gnawing of the neck is too regular an occurrence to be purposeless. Let us indulge in a digression which will tell us more about it. In June I often find on the lavender in the enclosure two small Crab Spiders {Thofnisus onustus, Walck.,^ and T. rotiindatus, Walck. ). One is satin- white and has pink and green rings round her legs; the other is inky-black and has an abdomen encircled with red with a foliaceous * Cf. The Life of the Spider: chap. viii. — Translator's Note. 129 The Life of the Grasshopper central patch. They are pretty Spiders, both of them, and they v/alk sideways, after the manner of Crabs. They do not know how to weave a hunting-net; the little silk which they possess is reserved exclusively for the downy satchel containing the eggs. Their plan of campaign therefore is to lie in am- bush on the flowers and to fling themselves unexpectedly on the quarry when it arrives on pilfering intent. Their favourite prey is the Hive-bee. I often come upon them with their prize, at times grabbed by the neck and at others by any part of the body, even the tip of a wing. In each and every case the Bee is dead, with her legs hanging limply and her tongue out. The poison-fangs planted in the neck sei: me thinking; I see in them a characteristic remarkably like the practice of the Mantis when starting on her Locust. And then arises another question : how does the weak Spider, who is vulnerable In every part of her soft body, manage to get hold of a prey like the Bee, stronger than herself, quicker in movement and armed v/ith a sting that can Inflict a mortal wound? The difference in physical strength and force of arms between assailant and assailed 130 The Mantis: her Hunting IS so very great that a contest of this kind seems impossible unless some netting inter- vene, some silken toils that can shackle and bind the formidable creature. The contrast would be no more intense were the Sheep to take it into her head to fly at the Wolf's throat. And yet the daring attack takes place and victory goes to the weaker, as is proved by the numbers of dead Bees whom I see sucked for hours by the Thomisl. The relative weakness must be made good by some special art; the Spider must possess a strategy that enables her to surmount the apparently insurmountable difliculty. To watch events on the lavender-borders would expose me to long, fruitless waits. It is better myself to make the preparations for the duel. I place a Thomisus under a cover with a bunch of lavender sprinkled with a few drops of honey. Some three or four live Bees complete the establishment. The Bees pay no heed to their redoubt- able neighbour. They flutter around the trellised enclosure; from time to time they go and take a sip from the honeyed flowers, sometimes quite close to the Spider, not a quarter of an inch aw^ay. They seem utterly unaware of their danger. The experience of 131 The Life of the Grasshopper centuries has taught them nothing about the terrible cut-throat. The Thomisus, on her side, waits motionless on a spike of lavender, near the honey. Her four front legs, which are longer than the others, are spread out and slightly raised, in readiness for attack. A Bee comes to drink at the drop of honey. This is the moment. The Spider springs forward and with her fangs seizes the im- prudent one by the tip of the wings, while her legs hold the victim in a tight embrace. A few seconds pass, during which the Bee struggles as best she can against the ag- gressor on her back, out of the reach of her dagger. This fight at close quarters cannot last long; the Bee would release herself from the other's grip. And so the Spider lets go the wing and suddenly bites her prey in the back of the neck. Once the fangs drive home, it is all over: death ensues. The Bee Is slain. Of her turbulent activity naught lingers but some faint quivers of the tarsi, final convulsions which are soon at an end. Still holding her prey by the nape of the neck, the Thomisus feasts not on the body, which remains Intact, but on the blood, which Is slowly sucked. When the neck Is drained dry, another spot Is attacked, on the ab- 132 The Mantis: her Hunting domen, the thorax, anywhere. This ex- plains why my observations in the open air showed me the Thomisus with her fangs fixed now in the neck, now in some other part of the Bee. In the first case, the cap- ture was a recent one and the murderess still retained her original posture; in the second case, it had been made some time before; and the Spider had forsaken the wound in the head, now sucked dry, to bite into some other juicy part, no matter which. Thus shifting her fangs, a trifle this way or that, as she drains her prey, the little ogress gorges on her victim's blood with voluptuous deliberation. I have seen the meal last for seven consecutive hours; and even then the prey was let go only because of the shock given to its devourer by my indiscreet examination. The abandoned corpse, a carcass of no value to the Spider, is not dismembered in any way. There is not a trace of bitten flesh, not a wound that shows. The Bee is drained of her blood; and that is all. My friend Bull, when he was alive, used to catch an enemy whose teeth threatened danger by the skin of the neck. His method is in general use throughout the canine race. 133 The Life of the Grasshopper There, In front of you, Is a growling pair of jaws, open, white with foam, ready to bite. The most elementary prudence ad- vises you to keep them quiet by catching hold of the back of the neck. In her fight with the Bee, the Spider has not the same object. What has she to fear from her victim? The sting before all things, the terrible dart whose least stab would destroy her. And yet she does not trouble about It. What she makes for Is the back of the neck, that alone and never anything else, so long as the prey remains alive. In so doing she does not aim at copy- ing the tactics of the Dog and depriving the head, which Is not particularly dangerous, of Its power of movement. Her plan Is far- ther-reaching and Is revealed to us by the lightning death of the Bee. The neck Is no sooner gripped than the victim expires. The cerebral centres therefore are injured, poi- soned with a deadly virus; and life Is straight- way extinguished at Its very seat. This avoids a struggle which, if prolonged, would certainly end In the aggressor's discomfiture. The Bee has her strength and her sting on her side; the delicate Thomlsus has on hers a profound knowledge of the art of murder. 134 The Mantis: her Hunting Let us return to the Mantis, who hkewlse has mastered the first principles of speedy and scientific klUIng, In which the little Bee- slaughtering Spider excels. A sturdy Lo- cust is captured; sometimes a powerful Grasshopper. The Mantis naturally wants to devour the victuals In peace, without be- ing troubled by the plunges of a victim who absolutely refuses to be devoured. A meal liable to interruptions lacks savour. Now the principal means of defence in this case are the hind-legs, those vigorous levers which can kick out so brutally and which moreover are armed with toothed saws that would rip open the Mantis' bulky paunch if by Ill-luck they happen to graze it. What shall we do to reduce them to helpless- ness, together with the others, which are not dangerous but troublesome all the same, with their desperate gesticulations ? Strictly speaking, It would be practicable to cut them off one by one. But that is a long process and attended with a certain risk. The Mantis has hit upon something better. She has an Intimate knowledge of the anatomy of the spine. By first attacking her prize at the back of the half-opened neck and munching the cervical ganglia, she de- I3S The Life of the Grasshopper stroys the muscular energy at Its main seat; and inertia supervenes, not suddenly and completely, for the clumsily-constructed Lo- cust has not the Bee's exquisite and frail vitality, but still sufficiently, after the first mouthfuls. Soon the kicking and the ges- ticulating die down, all movement ceases and the game, however big it be, is consumed in perfect quiet. Among the hunters, I have before now drawn a distinction between those who paralyse and those who kill.^ Both terrify one with their anatomical knowledge. To- day let us add to the killers the Thomisus, that expert in stabbing in the neck, and the Mantis, who, to devour a powerful prey at her ease, deprives it of movement by first gnawing its cervical ganglia. ^ Cf. The Hunting Wasps: passim. — Translator's Note. 136 CHAPTER VII THE MANTIS : HER LOVE-MAKING THE little that we have seen of the Mantis' habits hardly tallies with what we might have expected from her popular name. To judge by the term Prego-Dieu, we should look to see a placid insect, deep in pious contemplation; and we find ourselves in the presence of a cannibal, of a ferocious spectre munching the brain of a panic- stricken victim. Nor is even this the most tragic part. The Mantis has in store for us, In her relations with her own kith and kin, manners even more atrocious than those prevailing among the Spiders, who have an evil reputation in this respect. To reduce the number of cages on my big table and give myself a little more space while still retaining a fair-sized menagerie, I instal several females, sometimes as many as a dozen, under one cover. So far as accom- modation Is concerned, no fault can be found 137 The Life of the Grasshopper with the common lodging. There is room and to spare for the evokitions of my cap- tives, who naturally do not want to move about much with their unwieldy bellies. Hanging to the trelliswork of the dome, motionless they digest their food or else await an unwary passer-by. Even so do they act when at liberty in the thickets. Cohabitation has its dangers. I know that even Donkeys, those peace-loving ani- mals, quarrel when hay is scarce in the manger. My boarders, who are less com- plaisant, might well, in a moment of dearth, become sour-tempered and fight among them- selves. I guard against this by keeping the cages well supplied with Locusts, renewed twice a day. Should civil war break out, famine cannot be pleaded as the excuse. At first, things go pretty well. The com- munity lives in peace, each Mantis grabbing and eating whatever comes near her, with- out seeking strife with her neighbours. But this harmonious period does not last long. The bellies swell, the eggs are ripening in the ovaries, marriage and laying-time are at hand. Then a sort of jealous fury bursts out, though there Is an entire absence of males who might be held responsible for 138 The Mantis: her Love-making feminine rivalry. The working of the ovaries seems to pervert the flock, inspiring its members with a mania for devouring one another. There are threats, personal encounters, cannibal feasts. Once more the spectral pose appears, the hissing of the wings, the fearsome gesture of the grapnels outstretched and uplifted in the air. No hostile demonstration in front of a Grey Locust or White-faced Decticus could be more menacing. For no reason that I can gather, two neighbours suddenly assume their attitude of war. They turn their heads to right and left, provoking each other, exchanging in- sulting glances. The "Puff! Puff!" of the wings rubbed by the abdomen sounds the charge. When the duel is to be limited to the first scratch received, without more serious consequences, the lethal fore-arms, which are usually kept folded, open like the leaves of a book and fall back sideways, en- circling the long bust. It is a superb pose, but less terrible than that adopted in a fight to the death. Then one of the grapnels, with a sudden spring, shoots out to its full length and strikes the rival; it is no less abruptly with- 139 The Life of the Grasshopper drawn and resumes the defensive. The ad- versary hits back. The fencing Is rather like that of two Cats boxing each other's ears. At the first blood drawn from her flabby paunch, or even before receiving the least wound, one of the duellists confesses herself beaten and retires. The other furls her battle-standard and goes off elsewhither to meditate the capture of a Locust, keeping apparently calm, but ever ready to repeat the quarrel. Very often, events take a more tragic turn. At such times, the full posture of the duels to the death Is assumed. The mur- derous fore-arms are unfolded and raised In the air. Woe to the vanquished ! The other seizes her In her vice and then and there pro- ceeds to eat her, beginning at the neck, of course. The loathsome feast takes place as calmly as though It were a matter of crunch- ing up a Grasshopper. The diner enjoys her sister as she would a lawful dish; and those around do not protest, being quite willing to do as much on the first occasion. Oh, what savagery! Why, even Wolves are said not to eat one another. The Mantis has no such scruples; she banquets off her fellows when there Is plenty of her favourite 140 The Mantis: her Love-making game, the Locust, around her. She prac- tises the equivalent of cannibahsm, that hide- ous pecuharity of man. These aberrations, these child-bed crav- ings can reach an even more revolting stage. Let us watch the pairing and, to avoid the disorder of a crowd, let us isolate the couples under different covers. Each pair shall have its own home, where none will come to dis- turb the wedding. And let us not forget the provisions, with which we will keep them well supplied, so that there may be no ex- cuse of hunger. It is near the end of August. The male, that slender swain, thinks the moment pro- pitious. He makes eyes at his strapping companion; he turns his head in her direc- tion; he bends his neck and throws out his chest. His little pointed face wears an almost impassioned expression. Motionless, in this posture, for a long time he contemplates the object of his desire. She does not stir, is as though indifferent. The lover, however, has caught a sign of acquiescence, a sign of which I do not know the secret. He goes nearer; suddenly he spreads his wings, which quiver with a convulsive tremor. That is his declaration. He rushes, small as he is, upon 141 The Life of the Grasshopper the back of his corpulent companion, clings on as best he can, steadies his hold. As a rule, the preliminaries last a long time. At last, couphng takes place and is also long drawn out, lasting sometimes for five or six hours. Nothing worthy of attention happens be- tween the two motionless partners. They end by separating, but only to unite again in a more intimate fashion. If the poor fellow is loved by his lady as the vivifier of her ovaries, he is also loved as a piece of highly- flavoured game. And, that same day, or at latest on the morrow, he is seized by his spouse, who first gnaws his neck, in accord- ance with precedent, and then eats him de- liberately, by little mouthfuls, leaving only the wings. Here we have no longer a case of jealousy In the harem, but simply a de- praved appetite. I was curious to know what sort of recep- tion a second male might expect from a re- cently fertilized female. The result of my enquiry was shocking. The Mantis, in many cases, is never sated with conjugal raptures and banquets. After a rest that varies in length, whether the eggs be laid or not, a second male is accepted and then devoured 142 The Mantis: her Love-making like the first. A third succeeds him, per- forms his function in hfe, is eaten and dis- appears. A fourth undergoes a hke fate. In the course of two weeks I thus see one and the same Mantis use up seven males. She takes them all to her bosom and makes them all pay for the nuptial ecstasy with their lives. Orgies such as this are frequent, in vary- ing degrees, though there are exceptions. On very hot days, highly charged with elec- tricity, they are almost the general rule. At such times the Mantes are in a very irritable mood. In the cages containing a large colony, the females devour one another more than ever; in the cages containing separate pairs, the males, after coupling, are more than ever treated as an ordinary prey. I should like to be able to say, in mitiga- tion of these conjugal atrocities, that the Mantis does not behave like this in a state of liberty; that the male, after doing his duty, has time to get out of the way, to make off, to escape from his terrible mistress, for in my cages he is given a respite, lasting sometimes until next day. What really oc- curs in the thickets I do not know, chance, a poor resource, having never instructed me 143 The Life of the Grasshopper concerning the love-affairs of the Mantis when at large. I can only go by what hap- pens in the cages, where the captives, enjoy- ing plenty of sunshine and food and spacious quarters, do not seem to suffer from home- sickness in any way. What they do here they must also do under normal conditions. Well, what happens there utterly refutes the idea that the males are given time to escape. I find, by themselves, a horrible couple engaged as follows. The male, absorbed in the performance of his vital functions, holds the female in a tight em- brace. But the wretch has no head; he has no neck; he has hardly a body. The other, with her muzzle turned over her shoulder continues very placidly to gnaw what remains of the gentle swain. And, all the time, that masculine stump, holding on firmly, goes on with the business ! Love is stronger than death, men say. Taken literally, the aphorism has never re- ceived a more brilliant confirm-^tion. A headless creature, an insect amputated down to the middle of the chest, a very corpse per- sists in endeavouring to give life. It will not let go until the abdomen, the seat of the procreative organs, is attacked. 144 The Mantis: her Love-making Eating the lover after consummation of marriage, making a meal of the exhausted dwarf, henceforth good for nothing, can be understood, to some extent, in the insect world, which has no great scruples in mat- ters of sentiment; but gobbling him up dur- ing the act goes beyond the wildest dreams of the most horrible imagination. I have seen it done with my own eyes and have not yet recovered from my astonishment. Was this one able to escape and get out of the way, caught as he was in the midst of his duty? Certainly not. Hence we must infer that the loves of the Mantis are tragic, quite as much as the Spider's and perhaps even more so. I admit that the restricted space inside the cages favours the slaughter of the males; but the cause of these mas- sacres lies elsewhere. Perhaps it is a relic of the palaeozoic ages, when, in the carboniferous period, the in- sect came into being as the result of mon- strous amours. The Orthoptera, to whom the Mantes belong, are the first-born of the entomological world. Rough-hewn, incom- plete in their transformation, they roamed among the arborescent ferns and were al- ready flourishing when none of the insects 145 The Life of the Grasshopper with delicate metamorphoses, Butterflies, |/ Moths, Beetles, Flies and Bees, as yet ex- isted. Manners were not gentle in those days of passion eager to destroy in order to produce ; and the Mantes, a faint memory of the ghosts of old, might w^ell continue the amorous methods of a bygone age. The habit of eating the males is customary among other members of the Mantis family. I am indeed prepared to admit that it is general. The little Grey Mantis, who looks so sweet and so peaceable in my cages, never seeking a quarrel with her neighbours how- ever crowded they may be, bites into her male and feeds on him as fiercely as the Praying Mantis herself. I wear myself out, scouring the country to procure the Indis- pensable complement to my gynasceum. No sooner is my powerfully-winged and nimble prize introduced than, most often, he is clawed and eaten up by one of those who no longer need his aid. Once the ovaries are satisfied, the Mantes of both species abhor the male, or rather look upon him as no- thing better than a choice piece of venison. 146 CHAPTER VIII THE MANTIS: HER NEST T ET US show the insect of the tragic -*--' amours under a more attractive aspect. Its nest is a marvel. In scientific language It Is called ootheca, the egg-case. I shall not overwork this outlandish term. We do not say, " the Chaffinch's egg-case," when we mean, ''the Chaffinch's nest:" why should I be obliged to talk about a case when I speak of the Mantis? It may sound more learned; but that is not my business. The nest of the Praying Mantis is found more or less everywhere in sunny places, on stones, wood, vine-stocks, twigs, dry grass and even on products of human industry, such as bits of brick, strips of coarse linen or the hard, shrivelled leather of an old boot. Any support serves, without distinc- tion, so long as there Is an uneven surface to which the bottom of the nest can be fixed, thus securing a solid foundation. 147 The Life of the Grasshopper The usual dimensions are four centimetres in length and two in width/ The colour is as golden as a grain of wheat. When set alight, the material burns readily and ex- hales a faint smell of singed silk. The sub- stance is in fact akin to silk; only, instead of being drawn into thread, it has curdled into a frothy mass. When the nest is fixed ta a branch, the base goes round the nearest twigs, envelops them and assumes a shape which varies in accordance with the support encountered; when it is fixed to a flat sur- face, the under side, which is always moulded on the support, is itself flat. The nest thereupon takes the form of a semi- ellipsoid, more or less blunt at one end, tapering at the other and often ending in a short, curved tail. Whatever the support, the upper surface of the nest is systematically convex. We can distinguish in it three well-marked longi- tudinal zones. The middle one, which Is narrower than the others, is composed of little plates or scales arranged in pairs and overlapping like the tiles of a roof. The edges of these plates are free, leaving two parallel rows of slits or fissures through * 1.56 in. X .78 in. — Translator's Note. 148 The Mantis: her Nest which the young emerge at hatching-time. In a recently-abandoned nest, this middle zone is furry with gossamer skins, discarded by the larvs. These cast skins flutter at the least breath and soon vanish when exposed to rough weather. I will call it the exit- zone, because it is only along this median belt that the liberation of the young takes place, thanks to the outlets contrived before- hand. In every other part the cradle of the numerous family presents an impenetrable wall. The two side zones, in fact, which occupy the greater part of the semiellipsoid, have perfect continuity of surface. The little Mantes, so feeble at the start, could never make their way out through so tough a substance. All that we see on it is a num- ber of fine, transversal furrows, marking the various layers of which the mass of eggs consists. Cut the nest across. It will now be per- ceived that the eggs, taken together, form an elongated kernel, very hard and firm and coated on the sides with a thick, porous rind, like solidified foam. Above are curved plates, set very closely and almost mde- pendent of one another; their edges end in 149 The Life of the Grasshopper the exit-zone, where they form a double row of small, imbricated scales. The eggs are buried in a yellow matrix of horny appearance. They are placed in layers, shaped like segments of a circle, with the ends containing the heads converging to- wards the exit-zone. This arrangement tells us how the deliverance is accomplished. The new-born larvae will slip into the space left between two adjoining plates, a prolongation of the kernel, where they will find a narrow passage, difficult to go through, but just suf- ficient when we bear in mind the curious provision of which we shall speak presently; and by so doing they will reach the middle belt. Here, under the imbricated scales, two outlets open for each layer of eggs. Half of the larvae undergoing their liberation will emerge through the right door, half through the left. And this is repeated for each layer from end to end of the nest. To sum up these structural details, which are rather difficult to grasp for any one who has not the thing in front of him : lying along the axis of the nest and shaped like a date- stone is the cluster of eggs, grouped in layers. A protecting rind, a sort of solidified foam, surrounds this cluster, except at the top along 150 The Mantis: her Nest the median line, where the frothy rind is re- placed by thin plates set side by side. The free ends of these plates form the exit-zone outside; they are imbricated in two series of scales and leave a couple of outlets, narrow clefts, for each layer of eggs. The most striking part of my researches was being present at the construction of the nest and seeing how the Mantis goes to work to produce so complex a building. I managed it with some difficulty, for the lay- ing takes place without warning and nearly always at night. After much useless waiting, chance at last favoured me. On the 5th of September, one of my boarders, who had been fertilized on the 29th of August, de- cided to lay her eggs before my eyes at about four o'clock in the afternoon. Before watching her labour, let us note one thing: all the nests that I have obtained in the cages — and there are a good many of them — have as their support, with not a single exception, the wire gauze of the covers. I had taken care to place at the Mantes' disposal a few rough bits of stone, a few tufts of thyme, foundations very often used in the open fields. My captives pre- ferred the wire network, whose meshes fur- 151 The Life of the Grasshopper nish a perfectly safe support as the soft ma- terial of the building becomes encrusted in them. The nests, under natural conditions, enjoy no shelter; they have to endure the inclemen- cies of winter, to withstand rain, wind, frost and snow without coming loose. Therefore the mother always chooses an uneven sup- port for the nest, so that the foundations can be wedged into it and a firm hold ob- tained. But, when circumstances permit, the better is preferred to the middling and the best to the better; and this must be the reason why the trelliswork of the cages is invariably adopted. The only Mantis that I have been allowed to observe while engaged in laying does her work upside down, hanging from the top of the cage. My presence, my magnlfylng- glass, my investigations do not disturb her at all, so great is her absorption in her labour. I can raise the trellised dome, tilt it, turn It over, spin it this way and that, without the insect*s suspending its task for a moment. I can take my forceps and lift the long wings to see what is happening underneath. The Mantis takes no notice. Up to this point, all is well: the mother does not move and 152 The Mantis: her Nest impassively endures all the indiscretions of which I am guilty as an observer. And yet things do not go quite as I could wish, for the operation is too rapid and is too difficult to follow. The end of the abdomen is immersed the whole time in a sea of foam, which prevents us from grasping the details of the process with any clearness. This foam is greyish- white, a little sticky and almost like soapsuds. When it first appears, it adheres slightly to a straw which I dip into It, but, tv/o minutes afterwards, it is solidified and no longer sticks to the straw. In a very short time, its consistency is that which we find in an old nest. The frothy mass consists mainly of air Imprisoned in little bubbles. This air, v/hlch gives the nest a volume much greater than that of the Mantis' belly, obviously does not come from the Insect, though the foam appears at the entrance of the genital or- gans; It is taken from the atmosphere. The Mantis, therefore, builds above all with air, which Is eminently suited to protect the nest against the weather. She discharges a sticky substance, similar to the caterpillars' silk- fluid ; and with this composition, which amal- 153 The Life of the Grasshopper gamates Instantly with the outer air, she pro- duces foam. She whips her product just as we whip white of egg to make it rise and froth. The tip of the abdomen, opening with a long cleft, forms two lateral ladles which meet and separate with a constant, rapid move- ment, beating the sticky fluid and turning It Into foam as it is discharged outside. In addition, between the two flapping ladles, we see the Internal organs rising and falling, appearing and disappearing, after the manner of a piston-rod, without being able to distinguish their precise action, drowned as they are In the opaque stream of foam. The end of the abdomen, ever throbbing, quickly opening and closing its valves, swings from right to left and left to right like a pendulum. The result of each swing Is a layer of eggs Inside and a transversal furrow outside. As the abdomen advances In the arc described, suddenly and at very close Intervals It dips deeper into the foam, as though It were pushing something to the bottom of the frothy mass. Each time, no doubt, an egg Is laid; but things happen so fast and under conditions so unfavourable to observation that I never once succeed in 154 The Mantis: her Nest seeing the ovipositor at work. I can judge of the arrival of the eggs only by the move- ments of the tip of the abdomen, which sud- denly drives down and immerses itself more deeply. At the same time, the viscous stuff is poured forth in intermittent waves and whipped and turned into foam by the two terminal valves. The froth obtained spreads over the sides of the layer of eggs and at the base, where I see it, pressed back by the abdomen, projecting through the meshes of the gauze. Thus the spongy covering is gradually brought into being as the ovaries are emptied. I imagine, without being able to rely on direct observation, that for the central kernel, where the eggs are contained in a more homogeneous material than the rind, the Mantis employs her product as it is, with- out beating it up and making it foam. When the eggs are deposited, the two valves would produce foam to cover them. Once again, however, all this is very difficult to follow under the veil of the bubbling mass. In a new nest, the exit-zone is coated with a layer of fine porous matter, of a pure, dull, almost chalky white, which contrasts with 155 The Life of the Grasshopper the dirty white of the remainder of the nest. It is hke the composition which confectioners make out of whipped white of egg, sugar and starch, with which to ornament their cakes. This snowy covering is very easily crumbled and removed. When it is gone, the exit-zone is clearly defined, with its two rows of plates with free edges. The weather, the wind and the rain sooner or later remove it in strips and flakes; and therefore the old nests retain no traces of it. At the first inspection, one might be tempted to look upon this snowy matter as a different substance from the remainder of the nest. But can it be that the Mantis really employs two different products? By no means. Anatomy, to begin with, assures us of the unity of the materials. The organ that secretes the substance of the nest con- sists of tv/isted cylindrical tubes, divided into two sections of twenty each. All are filled with a colourless, viscous fluid, exactly similar in appearance wherever we look. There is nowhere any sign of a product with a chalky colouring. The manner in which the sno^vy ribbon is formed also makes us reject the theory of different materials. We see the Mantis' two 156 The Mantis: her Nest caudal threads sweeping the surface of the foamy mass, skimming, so to speak, the top of the froth, collecting it and retaining it along the back of the nest to form a band that looks like a ribbon of icing. What re- mains after this sweeping, or what trickles from the band before it sets, spreads over the sides in a thin wash of bubbles so fine that they cannot be seen without the magni- fying-glass. The surface of a muddy stream contain- ing clay will be covered with coarse and dirty foam, churned up by the rushing tor- rent. On this foam, soiled with earthy materials, we see here and there masses of beautiful white froth, with smaller bubbles. Selection is due to the difference in density; and so the snow-white foam in places lies on top of the dirty foam whence it proceeds. Something similar happens when the Mantis builds her nest. The twin ladles reduce to foam the sticky spray from the glands. The thinnest and lightest portion, made whiter by its more delicate porousness, rises to the surface, where the caudal threads sweep it up and gather it into a snowy ribbon along the back of the nest. Until now, with a little patience, observa- 157 The Life of the Grasshopper tlon has been practicable and has given satis- factory results. It becomes impossible when we come to the very complex structure of that middle zone where exits are contrived for the emergence of the larvse under the shelter of a double row of imbricated plates. The little that I am able to make out amounts to this : the tip of the abdomen, split wide from top to bottom, forms a sort of button- hole whose upper end remains almost fixed while the lower end, in swinging, produces foam and immerses eggs in it. It is that upper end which is undoubtedly responsible for the work of the middle zone. I always see it In the extension of that zone, in the midst of the fine white foam collected by the caudal filaments. These, one on the right, the other on the left, mark the boundaries of the band. They feel Its edges ; they seem to be testing the work. I can easily imagine them two long and exquisitely delicate fingers controlling the difHcult busi- ness of construction. But how are the two rows of scales ob- tained and the fissures, the exit-doors, which they shelter? I do not know. I cannot even guess. I leave the rest of the problem to others. 158 The Mantis: her Nest What a wonderful mechanism is this which emits so methodically and swiftly the horny matrix of the central kernel, the pro- tecting froth, the white foam of the median ribbon, the eggs and the fertilizing fluid and which at the same time is able to build over- lapping plates, imbricated scales and alter- nating open fissures! We are lost in ad- miration. And yet how easily the work is done ! The Mantis hangs motionless on the wire gauze which is the foundation of her nest. She gives not a glance at the edifice that is rising behind her; her legs are not called upon for assistance of any kind. The thing works of itself. We have here not an industrial task requiring the cunning of In- stinct; it is a purely automatic process, regu- lated by the insect's tools and organization. The nest, with Its highly complicated struc- ture, proceeds solely from the play of the organs, even as In our own Industries we manufacture by machinery a host of objects whose perfection would outwit our manual dexterity. / From another point of view, the Mantis' nest is more remarkable still. We see In It a superb application of one of the most beau- tiful principles of physics, that of the con- 159 The Life of the Grasshopper servatlon of heat. The Mantis anticipated us in a knowledge of non-conducting bodies. We owe to Rumford/ the natural phi- losopher, the following curious experiment, which fittingly demonstrates the low con- ductivity of the air. The Illustrious scientist dropped a frozen cheese Into a mass of foam supplied by well-beaten eggs. The whole was subjected to the heat of an oven. The result in a short time was an omelette soiifflee hot enough to burn the tongue, with the cheese In the middle as cold as at the beginning. The air contained In the bubbles of the surrounding froth explains the strange phenomenon. As an exceedingly poor thermal conductor, It had arrested the heat of the oven and prevented it from reaching the frozen substance In the centre. Now what does the Mantis do? Pre- cisely the same as Rumford : she whips her white of egg Into an omelette souffle e, to protect the eggs collected Into a central kernel. Her aim. It Is true. Is reversed: her coagulated foam Is Intended to ward off the cold, not the heat. But a protection against * Benjamin Thompson (1753-1814), an American loyal- ist, created Count Rumford in Bavaria, where he became minister for war. He discovered the convertibility of mechanical energy into heat. — Translator's Note. 160 The Mantis: her Nest one Is a protection against the other; and tlie ingenious physicist, had he wished, could easily with the same frothy wrapper have maintained the heat of a body in cold sur- roundings. Rumford knew the secrets of the stratum of air thanks to the accumulated knowledge of his ancestors, his own researches and his own studies. How is it that for no one knows how many centuries the Mantis has beaten our natural philosophers In the matter of this delicate problem of heat? How did she come to think of wrapping a blanket of foam around her mass of eggs, which, fixed without any shelter to a twig or stone, has to endure the rigours of winter with im- punity ? The other Mantldae of my neighbourhood, the only ones of whom I can speak with full knowledge, use the non-conducting wrapper of solidified foam or do without it, accord- ing as the eggs are destined to live through the winter or not. The little Grey Mantis, who differs so greatly from the other owing to the almost entire absence of wings in the female, builds a nest not quite so big as a cherry-stone and covers it very cleverly with a rind of froth. Why this beaten-up en- i6i The Life of the Grasshopper velope? Because the nest of the Grey- Mantis, Hke that of the Praying Mantis, has to last through the winter, exposed on its bough or stone to all the dangers of the bad weather. On the other hand, in spite of her size, which Is equal to that of the Praying Mantis, Empusa patiperata, who is the most curious of our Insects, builds a nest as small as that of the Grey Mantis. It is a very modest edifice, consisting of a small number of cells set side by side in three or four rows joined together. Here there is no frothy envelope at all, though the nest, like those mentioned above. Is fixed In an exposed situation on some twig or broken stone. This absence of a non- conducting mattress points to a difference In climatic conditions. The Empusa's eggs, In fact, hatch soon after they are laid, during the fine weather. Not having to undergo the Inclemencies of winter, they have no pro- tection but the slender sheath of their cases. Are these scrupulous and rational precau- tions, which rival Rumford's omelette soiif- fiee, a casual result, one of those numberless combinations turned out by the wheel of for- tune? If so, let us not shrink from any absurdity, but recognize straightway that the 162 The Mantis: her Nest blindness of chance is endowed with mar- vellous foresight. The blunt end of the nest is the first part built by the Praying Mantis and the tapering end the last. The latter is often prolonged into a sort of spur made by drawing out the final drop of albuminous fluid used. To complete the whole thing demands about two hours of concentrated work, free from interruption. As soon as the laying is finished, the mother withdraws, callously. I expected to see her return and display some tender feel- ing for the cradle of her family. But there is not the least sign of maternal joy. The work is done and possesses no further interest for her. Some Locusts have come up. One even perches on the nest. The Mantis pays no attention to the intruders. They are peaceful, it is true. Would she drive them away if they were dangerous and if they looked like ripping open the egg-casket? Her impassive behaviour answers no. What is the nest to her henceforth? She knows it no more. I have spoken of the repeated coupling of the Praying Mantis and of the tragic end of the male, who is nearly always devoured like 163 The Life of the Grasshopper an ordinary piece of game. In the space of a fortnight I have seen the same female marry again as many as seven times over. Each time the easily-consoled widow ate up her mate. Such habits make one assume re- peated layings; and these do, in fact, take place, though they are not the general rule. Among my mothers, some gave me only one nest; others supplied me with two, both equally large. The most fertile produced three, of which the first two were of normal size, while the third was reduced to half the usual dimensions. The last-mentioned insect shall tell us the population which the Mantis' ovaries are capable of producing. Reckoning by the transversal furrows of the nest, we can easily count the layers of eggs. These are more or less rich according to their position at the middle of the ellipsoid or at the ends. The numbers of the eggs in the biggest and in the smallest layer furnish an average from which we can approximately deduce the total. In this way I find that a good-sized nest con- tains about four hundred eggs. The mother with the three nests, the last of which was only half the size of the others, therefore left as her offspring no fewer than a thou- 164 The Mantis: her Nest sand germs; those who laid twice left eight hundred; and the less fertile mothers three to four hundred. In every case, it is a fine family, which would even become cumbrous, if it were not subjected to drastic pruning. The pretty little Grey Mantis is much less lavish. In my cages she lays only once ; and her nest contains some sixty eggs at most. Although built on the same principles and likewise fixed in the open, it differs remark- ably from the work of the Praying Mantis, first in Its scanty dimensions and next In cer- tain details of structure. It is shaped like a shelving ridge. The two sides are curved and the median line projects into a slightly denticulated crest. It is grooved crosswise by about a dozen furrows, corresponding with the several layers of eggs. Here we find no exit-zone, with short. Imbricated scales ; no snowy ribbon with alternating out- lets. The whole surface, including the foundation, is uniformly covered with a shiny red-brown rind, in which the bubbles are very small. One end Is oglval In shape; the other, the end where the nest finishes, is abruptly truncated and Is prolonged above In a short spur. The whole forms a kernel surrounded by the foamy rind. Like the Praying i6s The Life of the Grasshopper Mantis, the Grey Mantis works at night, an unfortunate circumstance for the observer. Large in size, curious in build and more- over plainly visible on its stone or its bit of brushwood, the Praying Mantis' nest could not fail to attract the attention of the Pro- vencal peasant. It is, in fact, very well- known in the country districts, where it bears the name of tigno; it even enjoys a great reputation. Yet nobody seems to be aware of its origin. It is always a matter for sur- prise to my rustic neighbours when I inform them that the famous t'lgno is the nest of the common Prego-Dieu. Their ignorance might well be due to the Mantis' habit of laying her eggs at night. The insect has never been caught working at her nest in the mysterious darkness; and the link between the worker and the work is missing, though both are known to every one in the village. No matter: the singular object exists; it attracts the eye, it captivates the attention. It must therefore be good for something, it must possess virtues. Thus, throughout the ages, have the ingenuous argued, hoping to find in the unfamiliar an alleviation of their pains. By general consent, the rural pharma- i66 The Mantis: her Nest copoeia, in Provence, extols the ti^no as the best remedy against chilblains. The way to employ it is exceedingly simple. You cut the thing in two, squeeze it and rub the afflicted part with the streaming juice. The remedy, they say, works like a charm. Every one mad with the itching of blue and swollen fingers hastens to have recourse to the tigno, according to traditional custom. Does he really obtain relief? Notwithstanding the unanimous convic- tion, I venture to doubt it, after the fruitless experiments tried upon myself and other members of my household during the winter of 1895, when the long and severe frost pro- duced any amount of epidermic discomfort. Not one of us, when smeared with the cele- brated ointment, saw the chilblains on his fingers decrease nor felt the irritation re- lieved in the slightest degree by the al- buminous varnish of the crushed tigno. It seems probable that others are no more suc- cessful and that the popular reputation of the specific nevertheless survives, probably because of a mere identity of name between the remedy and the disease : the Provencal for chilblain is tigno. Once that the nest of the Praying Mantis and the chilblain are 167 The Life of the Grasshopper known by the same name, do not the virtues of the former become obvious? That is how reputations are created. In my village and no doubt for some di- stance around, the li^no — I am now speaking of the Mantis' nest — is also highly praised as a wonderful cure for toothache. As long as you have it on you, you need never fear that trouble. Our housewives gather it under a favourable moon; they preserve It religiously In a corner of the press; they sew It Into their pocket, lest they should lose It when taking out their handkerchief; and neighbours borrow It w^hen tortured by some molar. *' Lend me your ttgno: I am In agony," says the sufferer with the swollen face. The other hastens to unstitch and to hand over the precious object: " Don't lose It, whatever you do," she Impresses on her friend. '' It's the only one I have ; and this Isn't the right time of moon." Let us not laugh at this eccentric toothache-nostrum: many remedies that sprawl triumphantly over the back pages of the newspapers are no more effective. Besides, this rural simplicity Is surpassed by some old books In which slumbers the i68 The Mantis: her Nest science of by-gone days. An English natural- ist of the sixteenth century, Thomas Moffett, the physician,^ tells us that, if a child lose his way in the country, he will ask the Mantis to put him on his road. The Mantis, adds the author, " will stretch out one of her feet and shew him the right way and seldome or never misse." These charm- ing things are told with adorable simplicity : '' Tarn divina censetur bestiola, iit puero interroganti de via, extent o digito rectam monstrat atque raro vel nunquam fallat/' Where did the credulous scholar get this pretty story? Not in England, where the Mantis cannot live; not In Provence, where we find no trace of the boyish question. All said, I prefer the splflicating virtues of the tigno to the old naturalist's imaginings. * Thomas Moffett, Moufet, or Muffet (1553-1604), au- thor of a posthumous Insectorum sive Minimorur.i Animalium Teatrnm, published in Latin in 1634 and in an English translation, by Edward Topsell, in 1658. Al- though giving credence to too many fabulous reports, Moffett was acknowledged the prince of entomologists prior to the advent of Jan Swamraerdam (1637-1680). — Translator's Note. 169 CHAPTER IX THE MANTIS: HER HATCHING THE eggs of the Praying Mantis usually hatch in bright sunshine, at about ten o'clock on a mid- June morning. The median band or exit-zone is the only portion of the nest that affords an outlet to the youngsters. From under each scale of that zone we see slowly appearing a blunt, transparent protuberance, followed by two large black specks, which are the eyes. Softly the new- born grub slips under the thin plate and half- releases itself. Is it the little Mantis in his larval form, so nearly allied to that of the adult? Not yet. It is a transition organism. The head is opalescent, blunt, swollen, with palpitations caused by the flow of the blood. The rest is tinted reddish-yellow. It is quite easy to distinguish, under a general overall, the large black eyes clouded by the veil that covers them, the mouth-parts flattened against the chest, the legs plastered to the 170 The Mantis: her Hatching body from front to back. Altogether, with the exception of the very obvious legs, the whole thing, with its big blunt head, its eyes, its delicate abdominal segmentation and its boatlike shape, reminds us somewhat of the first state of the Cicadae on leaving the egg, a state which is pictured exactly by a tiny, finless fish. Here then is a second instance of an or- ganization of very brief duration having as its function to bring into the light of day, through narrow and difficult passes, a micro- scopic creature whose limbs, if free, would, because of their length, be an insurmountable impediment. To enable him to emerge from the exiguous tunnel of his twig, a tunnel bristling with woody fibres and blocked with shells already empty, the Cicada is born swathed in bands and endowed with a boat shape, which is eminently suited to slipping easily through an awkward passage. The young Mantis is exposed to similar difficult- ies. He has to emerge from the depths of the nest through narrow, winding ways, in which full-spread, slender limbs would not be able to find room. The high stilts, the mur- derous harpoons, the delicate antennae, or- gans which will be most useful presently, in 171 The Life of the Grasshopper the brushwood, would now hinder the emer- gence, would make it very laborious, impossi- ble. The creature therefore comes into ex- istence swaddled and furthermore takes the shape of a boat. The case of the Cicada and the Mantis opens up a new vein to us in the inexhaustible entomological mine. I extract from it a law which other and similar facts, picked up more or less everywhere, will certainly not fail to confirm. The true larva is not always the direct product of the egg. When the new- born grub is likely to experience special dif- ficulties in effecting its deliverance, an access- ory organisjn, which I shall continue to call the primary larva, precedes the genuine larval state and has as its function to bring to the light of day the tiny creature which is incapable of releasing itself. To go on with our story, the primary larvae show themselves under the thin plates of the exit-zone. A vigorous flow of hu- mours occurs in the head, swelling it out and converting it Into a diaphanous and ever- throbbing blister. In this way the splitting- apparatus is prepared. At the same time, the little creature, half-caught under its scale, sways, pushes forward, draws back. Each 172 The Mantis: her Hatching swaying Is accompanied by an increase of the swelling in the head. At last the pro- thorax arches and the head is bent low towards the chest. The tunic bursts across the prothorax. The little animal tugs, wriggles, sways, bends and straightens itself again. The legs are drawn from their sheaths; the antennae, two long parallel threads, are likewise released. The creature is now fastened to the nest only by a worn- out cord. A few shakes complete the de- liverance. We here have the insect in its genuine larval form. All that remains behind is a sort of irregular cord, a shapeless clout which the least breath blows about like a flimsy bit of fluff. It is the exit-tunic vio- lently shed and reduced to a mere rag. For all my watchfulness, I missed the mo- ment of hatching in the case of the Grey Mantis. The little that I know is reduced to this : at the end of the spur or promontory with which the nest finishes in front Is a small, dull-white speck, formed of very powdery foam. This round pore is only just plugged with a frothy stopper and constitutes the sole outlet from the nest, which is thoroughly strengthened at every other part. It takes 173 The Life of the Grasshopper the place of the long band of scales through which the Praying Mantis is released. It is here that the youngsters must emerge one by one from their casket. Chance does not favour me and I do not witness the exodus, but, soon after the family has come forth, I see dangling at the entrance to the libera- ting pore a shapeless bunch of white cast-off clothes, thin skins which a puff of wind would disperse. These are the garments flung aside by the young as they make their appearance in the open air; and they testify to the presence of a transition wrapper which permits of movement inside the maze of the nest. The Grey Mantis therefore also has her primary larva, which packs itself up in a narrow sheath, conducive to escape. The period of this emergence is June. To return to the Praying Mantis. The hatching does not take place all over the nest at one time, but rather in sections, in successive swarms which may be separated by intervals of two days or more. The pointed end, containing the last eggs, usually begins. This inversion of chronological or- der, calling the last to the light of day before the first, may well be due to the shape of the nest. The thin end, which is more ac- 174 The Mantis: her Hatching cessible to the stimulus of a fine day, wakes up before the blunt end, which is larger and does not so soon acquire the necessary- amount of heat. Sometimes, however, although still broken up in swarms, the hatching embraces the whole length of the exit-zone. A striking sight indeed is the sudden exodus of a hun- dred young Mantes. Hardly does the tiny I creature show its black eyes under a scale be- fore others appear instantly, in their num- bers. It is as though a certain shock were being communicated from one to another, as though an awakening signal were trans- mitted, so swiftly does the hatching spread all round. Almost in a moment the median band is covered with young Mantes who run about feverishly, stripping themselves of their rent garments. The nimble little creatures do not stay long on the nest. They let themselves drop off or else clamber into the nearest foliage. All is over in less than twenty minutes. The common cradle resumes its peaceful condi- tion, prior to furnishing a new legion a few days later; and so on until all the eggs are finished. I have witnessed this exodus as often as 175 The Life of the Grasshopper I wished to, either out of doors, in my en- closure, where I had deposited in sunny places the nests gathered more or less every- where during my winter leisure, or else in the seclusion of a greenhouse, where I thought, in my simplicity, that I should be better able to protect the budding family. I have witnessed the hatching twenty times if I have once; and I have always beheld a scene of unforgetable carnage. The round- bellied Mantis may procreate germs by the thousands : she will never have enough to cope with the devourers who are destined to decimate the breed from the moment that it leaves the egg. The Ants above all are zealous extermina- tors. Daily I surprise their ill-omened visits on my rows of nests. It Is vain for me to intervene, however seriously; their assi- duity never slackens. They seldom succeed in making a breach in the fortress : that is too difficult; but, greedy of the dainty flesh in course of formation inside, they await a favourable opportunity, they lie in wait for the exit. Despite my dally watchfulness, they are there the moment that the young Mantes ap- pear. They grab them by the abdomen, pull 176 The Mantis: her Hatching them out of their sheaths, cut them up. You see a piteous fray between tender babes gesticulating as their only means of defence and ferocious brigands carrying their spolia opinia at the end of their mandibles. In less than no time the massacre of the innocents is consummated; and all that remains of the flourishing family is a few scattered survivors who have escaped by accident. The future assassin, the scourge of the insect race, the terror of the Locust on the brushwood, the dread devourer of fresh meat, is herself devoured, from her birth, by one of the least of that race, the Ant. The ogress, prolific to excess, sees her family thinned by the dwarf. But the slaughter is not long continued. So soon as she has ac- quired a little firmness from the air and strengthened her legs, the Mantis ceases to be attacked. She trots about briskly among the Ants, who fall back as she passes, no longer daring to tackle her. With her grappling-legs brought close to her chest, like arms ready for self-defence, already she strikes awe into them by her proud bearing. A second connoisseur in tender meats pays no heed to these threats. This Is the little Grey Lizard, the lover of sunny walls. Ap- 177 The Life of the Grasshopper prised I know not how of the quarry, here he comes, picking up one by one, with the tip of his slender tongue, the stray insects that have escaped the Ants. They make a small mouthful but an exquisite one, so it seems, to judge by the blinking of the reptile's eye. For each little wretch gulped down, its lid half-closes, a sign of profound satisfaction. I drive away the bold Lizard who ventures to perpetrate his raid before my eyes. He comes back again and, this time, pays dearly for his rashness. If I let him have his way, I should have nothing left. Is this all? Not yet. Another ravager, the smallest of all but not the least formida- ble, has anticipated the Lizard and the Ant. This is a very tiny Hymenopteron armed with a probe, a Chalcis, who establishes her eggs in the newly-built nest. The Mantis' brood shares the fate of the Cicada's: parasitic vermin attack the eggs and empty the shells. Out of all that I have collected I often obtain nothing or hardly anything. The Chalcis has been that way. Let us gather up what the various ex- terminators, known or unknown, have left me. When newly hatched, the larva is of a pale hue, white faintly tinged with yellow. 178 The Mantis: her Hatching The swelling of its head soon diminishes and disappears. Its colour is not long in darken- ing and turns light-brown within twenty-four hours. The little Mantis very nimbly lifts up her grappiing-legs, opens and closes them; she turns her head to right and left; she curls her abdomen. The fully-developed larva has no greater litheness and agility. For a few minutes the family stops where it is, swarming over the nest; then it scatters at random on the ground and the plants hard I instal a few dozen emigrants under bell- covers. On what shall I feed these future huntresses? On game, obviously. But what game? To these miniature creatures I can only offer atoms. I serve them up a rose- branch covered with Green Fly. The plump Aphis, a tender morsel suited to my feeble guests, is utterly scorned. Not one of the captives touches it. I try them with Midges, the smallest that chance flings into my net as it sweeps the grass, and meet with the same obstinate re- fusal. I offer them pieces of Fly, hung here and there on the gauze of the cover. None accepts my quarters of venison. Perhaps the Locust will tempt them, the Locust on 179 The Life of the Grasshopper whom the adult Mantis dotes? A prolonged and minute search places me in possession of what I want. This time the bill of fare will consist of a few recently hatched Acridians. Young as they are, they have already reached the size of my charges. Will the little Mantes fancy these? They do not fancy them : at the sight of their tiny prey they run away dismayed. Then what do you want? What other game do you find on your native brushwood? I can see nothing. Can you have some special infants' food, vegetarian perhaps? Let us even try the improbable. The very tenderest bit of the heart of a lettuce is de- clined. So are the different sorts of grass which I tax my Ingenuity in varying; so are the drops of honey which I place on spikes of lavender. All my endeavours come to nothing; and my captives die of inanition. My failure has Its lessons. It seems to point to a transition diet which I have not been able to discover. Long ago, the larvae of the Oil-beetles gave me a great deal of trouble, before I knew that they want as their first food the egg of the Bee whose store of honey they will afterwards consume. Per- haps the young Mantes also in the begin- i8o The Mantis: her Hatching ning demand a special pap, something more in keeping with their fraiky. Despite Its resolute air, I do not quite see the feeble little creature hunting. The game, what- ever it be, kicks out, when attacked, frisks about, defends itself; and the assailant is not yet in a condition to ward oft even the flap of a Midge's wing. Then what does it feed on? I should not be surprised if there were Interesting facts to be picked up In this baby-food question. These fastidious ones, so difficult to pro- vide with nourishment, meet with even more pitiful deaths than hunger. When only just born, they fall a prey to the Ant, the Lizard and other ravagers who lie in wait, patiently, for the exquisite provender to hatch. The egg Itself is not respected. An Infinitesimal perforator Inserts her own eggs In the nest through the barrier of solidified foam, thus settling her offspring, which, maturing ear- lier, nips the Mantis' family In the bud. How many are called and how few are chosen ! There were a thousand of them perhaps, sprung from one mother who was capable of giving birth to three broods. One couple alone escapes extermination, one alone keeps up the breed, seeing that the number re- i8i The Life of the Grasshopper mains more or less the same from year to year. Here a serious question arises. Can the Mantis have acquired her present fecundity by degrees? Can she, as the ravages of the Ant and others reduced her progeny, have increased the output of her ovaries so as to make up for excessive destruction by ex- cessive production? Could the enormous brood of to-day be due to the wastage of former days? So think some, who are ready, without convincing proofs, to see in animals even more profound changes brought about by circumstances. In front of my window, on the sloping margin of the pond, stands a magnificent cherry-tree. It came there by accident, a sturdy wilding, disregarded by my prede- cessors and to-day respected far more for its spreading branches than for Its fruit, which is of very indifferent quality. In April it forms a splendid white-satin dome. Its blossoms are as snow; their fallen petals car- pet the ground. Soon the red cherries ap- pear in profusion. O my beautiful tree, how lavish you are and what a number of baskets you will fill ! And for this reason what revelry up 182 The Mantis: her Hatching above I The Sparrow is the first to hear of the ripe cherries and comes trooping, morn- ing and evening, to pilfer and squall; he in- forms his friends in the neighbourhood, the Greenfinch and the Warbler, who hasten up and banquet for weeks on end. Butterflies flit from one nibbled cherry to another, taking delicious sips at each. Rose-chafers bite great mouthfuls out of the fruit, then fall asleep sated. Wasps and Hornets burst open the sweet caskets ; and the Gnats follow to get drunk in their wake. A plump mag- got, settled in the very centre of the pulp, blissfully feasts upon its juicy dwelling-house and waxes big and fat. It will rise from table to change into a comely Fly. On the ground there are others at the banquet. A host of footpads is battening on the fallen cherries. At night, the Field- mice come gathering the stones stripped by the Wood-lice, Earwigs, Ants and Slugs; they hoard them in their burrows. During the long winter they will make holes in them to extract and nibble the kernels. A num- berless throng lives upon the generous cherry- tree. What would the tree require to provide a successor one day and maintain Its species 183 The Life of the Grasshopper in a state of harmonious and well-balanced prosperity? A single seed would be enough; and every year it gives forth bushels and bushels. Tell me why, please. Shall we say that the cherry-tree, at first very economical with its fruit, became lavish by degrees In order thus to escape Its multi- tudinous ravagers? Shall we say of the tree, as we said of the Mantis, that excessive de- struction gradually Induced excessive produc- tion? Who would dare to venture on such rash statements? Is It not perfectly obvious that the cherry-tree is one of those factories in which elements are wrought into organic matter, one of those laboratories in which the dead thing is changed into the thing fitted to live? No doubt, cherries ripen that they may be perpetuated; but these are the minority, the very smxall minority. If all seeds were to sprout and to develop fully, there would long ago have been no room on the earth for the cherry-tree alone. The vast majority of its fruits fulfil another func- tion. They serve as food for a crov/d of living creatures, who are not skilled as the plant is in the transcendental chemistry that turns the uneatable into the eatable. Matter, in order to serve in the highest 184 The Mantis: her Hatching manifestations of life, must undergo slow and most delicate elaboration. That elabo- ration begins in the workshop of the infinitely small, of the microbe, for instance, one of which, more powerful than the lightning's might, combines oxygen and nitrogen and produces nitrates, the primary food of plants. It begins on the confines of nothing- ness, is improved in the vegetal, is yet further refined in the animal and step by step attains the substance of the brain. How many hidden labourers, how many unknown manipulators worked perhaps for centuries, first at getting the rough ore and then at the refinin,o: of that grey matter which becomes the brain, the most marvellous of the implements of the mind, even if it were capable only of making us say : " Two and two are four! " The rocket, when rising, reserves for the culminating point of its ascent the dazzling fountain of its many-coloured lights. Then all is dark again. Its smoke, its gases, its oxides will, in the long run, be able to recon- stitute other explosives by vegetable pro- cesses. Even so does matter act In Its metat morphoses. From stage to stage, from one delicate refinement to another yet more dell- The Life of the Grasshopper cate, It succeeds In attaining heights where the splendours of the intellect shine forth through Its agency; then, shattered by the effort, It relapses Into the nameless thing whence It started, Into scattered molecules which are the common origin of living things. At the head of the assemblers of organic matter stands the plant, the animal's senior. Directly or Indirectly, It Is to-day, as It was In the geological period, the chief purveyor to beings more generously endowed with life. In the laboratory of its cell the food of the universe at least gets Its first rough prepara- tion. Comes the animal, which corrects the preparation. Improves It and transmits It to others of a higher order. Cropped grass becomes mutton ; and mutton becomes human flesh or Wolf-flesh, according to the con- sumer. Among those elaborators of nourishing atoms which do not create organic matter out of any- and everything, starting with the mineral, as the plant does, the most prolific are the fishes, the first-born of vertebrate animals. Ask the Cod v/hat she does with her millions of eggs. Her answer will be that of the beech with Its myriads of nuts, or the oak with its myriads of acorns. She i86 The Mantis: her Hatching is immensely fruitful in order to feed an im- mense number of the hungry. She is con- tinuing the work which her predecessors per- formed in remote ages, when nature, not as yet rich in organic matter, hastened to in- crease her reserves of life by bestowing prodigious exuberance upon her primeval workers. The Mantis, like the fish, dates back to those distant epochs. Her strange shape and her uncouth habits have told us so. The richness of her ovaries confirms it. She re- tains in her entrails a feeble relic of the pro- creative fury that prevailed in olden times under the dank shade of the arborescent ferns; she contributes, in a very humble but none the less real measure, to the sublime alchemy of living things. Let us look closely at her work. The grass grows thick and green, drawing its nourishment from the earth. The Locust crops it. The Mantis makes a meal of the Locust and swells out with eggs, which are laid, in three batches, to the number of a thousand. When they hatch, up comes the Ant and levies an enorm.ous tribute on the brood. We appear to be retroceding. In vastness of bulk, yes; in refinement of In- 187 The Life of the Grasshopper stlnct, certainly not. In this respect how far superior is the Ant to the Mantis ! Besides, the cycle of possible happenings is not closed. Young Ants still contained in their cocoon — popularly known as Ants'-eggs — form the food on which the Pheasant's brood is reared. These are domestic poultry just as much as the Pullet and the Capon, but their keep makes greater demands on the owner's care and purse. When it grows big, this poultry is let loose in the woods; and people calling themselves civilized take the greatest pleasure In bringing down with their guns the poor creatures which have lost the in- stinct of self-preservation In the pheasantries, or, to speak plainly, In the poultry-yard. You cut the throat of the Chicken required for roasting; you shoot, with all the parade of sport, that other Chicken, the Pheasant. I fail to understand those Insensate mas- sacres. Tartarin of Tarascon, In the absence of game, used to shoot at his cap. I prefer that. And above all T prefer the hunting, real hunting, of another fervent consumer of Ants, the Wryneck, the Tiro-lengo of the Provengaux, so-called because of his scien- tific method of darting his Immensely-long i88 The Mantis: her Hatching and sticky tongue across a procession of Ants and then suddenly withdrawing it all black with the limed insects. With such mouthfuls as these, the Wryneck becomes disgracefully fat in autumn ; he plasters himself with butter on his rump and sides and under his wings; he hangs a string of it round his neck; he pads his skull with it right down to the beak. He is then delicious, roasted: small, I ad- mit; no bigger than a Lark, at the outside; but, small though he be, unlike anything else and immeasurably superior to the Pheasant, who must begin to go bad before developing a flavour at all. Let me for this once do justice to the merit of the humblest ! When the table is cleared after the evening meal and all is quiet and my body relieved for the time being of its physiological needs, sometimes I succeed in picking up, here and there, a good idea or two ; and it may well be that the Mantis, the Locust, the Ant and even lesser creatures contribute to these sudden gleams of light which flash unaccountably into one's mind. By strange and devious paths, they have all supplied, in their respective ways, the drop of oil that feeds the lamp of thought. Their energies, slowly developed, stored up and 189 The Life of the Grasshopper handed down by predecessors, become In- fused Into our veins and sustain our weak- ness. We live by their death. To conclude. The Mantis, prolific to ex- cess, In her turn makes organic matter, bequeathing It to the Ant, who bequeaths it to the Wryneck, who bequeaths It perhaps to man. She procreates a thousand, partly to perpetuate her species, but far more than she may contribute, according to her means, to the general picnic of the living. She brings us back to the ancient symbol of the Serpent biting Its ow^n tail. The world Is an endless circle : everything finishes so that everything may begin again; everything dies so that everything may live. 190 CHAPTER X THE EMPUSA THE sea, life's first foster-mother, still preserves in her depths many of those singular and incongruous shapes which were the earliest attempts of the animal kingdom; the land, less fruitful, but with more ca- pacity for progress, has almost wholly lost the strange forms of other days. The few that remain belong especially to the series of primitive insects, insects exceedingly limited in their industrial powers and subject to very summary metamorphoses, if to any at all. In my district, in the front rank of those entomological anomalies which remind us of the denizens of the old coal-forests, stand the Mantidas, including the Praying Mantis, so curious in habits and structure. Here also Is the Empusa {E. pauper ata, Latr.), the subject of this chapter. Her larva is certainly the strangest crea- ture among the terrestrial fauna of Pro- 191 The Life of the Grasshopper vence : a slim, swaying thing of so fantastic an appearance that uninitiated fingers dare not lay hold of it. The children of my neighbourhood, impressed by its startling shape, call it " the Devilkin." In their im- aginations, the queer little creature savours of witchcraft. One comes across it, though always sparsely, in spring, up to May; in autumn; and sometimes in winter, if the sun be strong. The tough grasses of the waste- lands, the stunted bushes which catch the sun and are sheltered from the wind by a few heaps of stones are the chilly Empusa's favourite abode. Let us give a rapid sketch of her. The abdomen, which always curls up so as to join the back, spreads paddlewise and twists into a crook. Pointed scales, a sort of foliaceous expansions arranged In three rows, cover the lower surface, which becomes the upper sur- face because of the crook aforesaid. The scaly crook Is propped on four long, thin stilts, on four legs armed with knee-pieces, that is to say, carrying at the end of the thigh, where It joins the shin, a curved, projecting blade not unlike that of a cleaver. Above this base, this four-legged stool, rises, at a sudden angle, the stiff corselet, 192 The Empusa disproportionately long and almost perpen- dicular. The end of this bust, round and slender as a straw, carries the hunting-trap, the grappling limbs, copied from those of the Mantis. They consist of a terminal har- poon, sharper than a needle, and a cruel vice, with jaws toothed like a saw. The jaw formed by the arm proper is hollowed into a groove and carries on either side five long spikes, with smaller indentations in be- tween. The jaw formed by the fore-arm is similarly furrowed, but its double saw, which fits into the groove of the upper arm when at rest, is formed of finer, closer and more regular teeth. The magnifying-glass reveals a score of equal points in each row. The machine only lacks size to be a fearful im- plement of torture. The head is in keeping with this arsenal. What a queer-shaped head it is ! A pointed face, with walrus moustaches furnished by the palpi; large goggle eyes; between them, a dirk, a halberd blade; and, on the fore- head, a mad, unheard-of thing: a sort of tall mitre, an extravagant head-dress that juts forward, spreading right and left into peaked wings and cleft along the top. What does the Devilkin want with that monstrous 193 The Life of the Grasshopper pointed cap, than which no wise man of the East, no astrologer of old ever wore a more splendiferous? This we shall learn when we see her out hunting. The dress is commonplace; grey tints pre- dominate. Towards the end of the larval period, after a few moultings, it begins to give a glimpse of the adult's richer livery and becomes striped, still very faintly, with pale-green, white and pink. Already the two sexes are distinguished by their anten- nae. Those of the future mothers are thread- like; those of the future males are distended into a spindle at the lower half, forming a case or sheath whence graceful plumes will spring at a later date. Behold the creature, worthy of a Callot's ^ fantastic pencil. If you come across it in the bramble-bushes, it sways upon its four stilts, it wags its head, it looks at you with a knowing air, it twists its mitre round and peers over its shoulder. You seem to read mischief in its pointed face. You try to take hold of it. The imposing attitude ceases forthwith, the raised corselet is lowered and * Jacques Callot (1592-1635), the French engraver and painter, famed for the grotesque nature of his subjects. — Translator's Note. 194 The Empusa the creature makes off with mighty strides, helping itself along with its fighting-limbs, which clutch the twigs. The flight need not last long, if you have a practised eye. The Empusa is captured, put into a screw of paper, which will save her frail limbs from sprains, and lastly penned in a wire-gauze cage. In this way, in October, I obtain a flock sufficient for my purpose. How to feed them? My Devilkins are very little; they are a month or two old at most. I give them Locusts suited to their size, the smallest that I can find. They refuse them. Nay more, they are frightened of them. Should a thoughtless Locust meekly approach one of the Empusae, sus- pended by her four hind-legs to the trellised dome, the Intruder meets with a bad recep- tion. The pointed mitre Is lowered; and an angry thrust sends him rolling. We have It: the wlzard^s cap Is a defensive weapon, a protective crest. The Ram charges with his forehead, the Empusa butts with her mitre. But this does not mean dinner. I serve up the House-fly, alive. She Is accepted, without hesitation. The moment that the Fly comes within reach, the watchful Devil- kin turns her head, bends the stalk of her 195 I The Life of the Grasshopper corselet slantwise and, flinging out her fore- limb, harpoons the Fly and grips her be- tween her two saws. No Cat pouncing upon a Mouse could be quicker. The game, however small, is enough for a meal. It is enough for the whole day, often for several days. This is my first surprise : the extreme abstemiousness of these savagely- armed insects. I was prepared for ogres : I find ascetics satisfied with a meagre colla- tion at rare intervals. A Fly fills their belly for twenty-four hours at least. Thus passes the late autumn: the Em- pusae, more and more temperate from day to day, hang motionless from the wire gauze. Their natural abstinence is my best ally, for Flies grow scarce; and a time comes when I should be hard put to it to keep the menageries supplied with provisions. During the three winter months, nothing stirs. From time to time, on fine days, I expose the cage to the sun's rays, in the window. Under the influence of this heat- bath, the captives stretch their legs a little, sway from side to side, make up their minds to move about, but without displaying any awakening appetite. The rare Midges that fall to my assiduous efforts do not appear to 196 The Empusa tempt them. It is a rule for them to spend the cold season in a state of complete abstinence. My cages tell me what must happen out- side, during the winter. Ensconced in the crannies of the rockwork, in the sunniest places, the young Empusae wait, in a state of torpor, for the return of the hot weather. Notwithstanding the shelter of a heap of stones, there must be painful moments when the frost is prolonged and the snow pene- trates little by little into the best-protected crevices. No matter: hardier than they look, the refugees escape the dangers of the winter season. Sometimes, when the sun is strong, they venture out of their hiding- place and come to see if spring be nigh. Spring comes. We are in March. My prisoners bestir themselves, change their skin. They need victuals. My catering diffi- culties recommence. The House-fly, so easy to catch, is lacking in these days. I fall back upon earlier Diptera : Eristales, or Drone- flies. The Empusa refuses them. They are too big for her and can offer too strenuous a resistance. She wards off their approach with blows of her mitre. A few tender morsels, in the shape of very 197 The Life of the Grasshopper young Grasshoppers, are readily accepted. Unfortunately, such wind-falls do not often find their way into my sweeping-net. Absti- nence becomes obligatory until the arrival of the first Butterflies. Henceforth, Pieris hrassica, the White Cabbage Butterfly, will contribike the greater portion of the victuals. Let loose In the wire cage, the Pieris is regarded as excellent game. The Empusa lies in wait for her, seizes her, but releases her at once, lacking the strength to over- power her. The Cabbage Butterfly's great wings, beating the air, give her shock after shock and compel her to let go. I come to the weakling's assistance and cut the wings of her prey with my scissors. The maimed ones, still full of life, clamber up the trellis- work and are forthwith grabbed by the Em- pusae, who, In no way frightened by their protests, crunch them up. The dish Is to their taste and, moreover, plentiful, so much so that there are always some despised remnants. The head only and the upper portion of the breast are devoured : the rest — the plump abdomen, the best part of the thorax, the legs and lastly, of course, the wing-stumps — is flung aside untouched. Does this mean that 198 The Empusa the tenderest and most succulent morsels are chosen? No, for the belly is certainly more juicy; and the Empusa refuses it, though she eats up her House-fly to the last particle. It is a strategy of war. I am again in the presence of a neck-specialist as expert as the Mantis herself in the a,rt of swiftly slaying a victim that struggles and, in struggling, spoils the meal. Once warned, I soon perceive that the game, be it Fly, Locust, Grasshopper or Butterfly, Is invariably struck in the neck, from behind. The first bite is aimed at the point containing the cervical ganglia and produces sudden death or immobility. Com- plete Inertia will leave the consumer in peace, the essential condition of every satis- factory repast. The Devilkin, therefore, frail though she be, possesses the secret of Immediately de- stroying the resistance of her prey. She bites at the back of the neck first, in order to give the finishing stroke. She goes on nibbling around the original attacking-polnt. In this way, the Butterfly's head and the upper part of the breast are disposed of. But, by that time, the huntress Is surfeited : she wants so little ! The rest lies on the 199 The Life of the Grasshopper ground, disdaixned, not for lack of flavour, but because there is too much of it. A Cab- bage Butterfly far exceeds the capacity of the Empusa's stomach. The Ants will bene- fit by what is left. There is one other matter to be mentioned, before observing the metamorphosis. The position adopted by the young Empusae in the wire-gauze cage is invariably the same from start to finish. Gripping the trellis- work by the claws of its four hind-legs, the insect occupies the top of the dome and hangs motionless, back downwards, with the whole of its body supported by the four suspension- points. If it wishes to move, the front har- poons open, stretch out, grasp a mesh and draw it to them. When the short walk is over, the lethal arms are brought back against the chest. One may say that it is nearly always the four hind-shanks which alone support the suspended insect. And this reversed position, which seems to us so trying, lasts for no short while : it is prolonged, in my cages, for ten months without a break. The Fly on the ceiling, it is true, occupies the same attitude; but she has her moments of rest: she flies, she walks in a normal posture, she spreads herself flat 200 The Empusa In the sun. Besides, her acrobatic feats do not cover a long period. The Empusa, on the other hand, maintains her curious equihbrlum for ten months on end, without a break. Hanging from the trelllswork, back downwards, she hunts, eats, digests, dozes, casts her skin, undergoes her trans- formation, mates, lays her eggs and dies. She clambered up there when she was still quite young; she falls down, full of days, a corpse. Things do not happen exactly like this under natural conditions. The insect stands on the bushes back upwards; it keeps its balance in the regular attitude and turns over only in circumstances that occur at long in- tervals. The protracted suspension of my captives is all the more remarkable inasmuch as it is not at all an innate habit of their race. It reminds one of the Bats, who hang, head downwards, by their hind-legs from the roof of their caves. A special formation of the toes enables birds to sleep on one leg, which automatically and without fatigue clutches the swaying bough. The Empusa shows me nothing akin to their contrivance. The extremity of her walking-legs has the 201 The Life of the Grasshopper ordinary structure : a double claw at the tip, a double steelyard-hook; and that is all. I could wish that anatomy would show me the working of the muscles and nerves In those tarsi, In those legs more slender than threads, the action of the tendons that con- trol the claws and keep them gripped for ten months, unwearied In waking and sleep- ing. If some dexterous scalpel should ever Investigate this problem, I can recommend another, even more singular than that of the Empusa, the Bat and the bird. I refer to the attitude of certain Wasps and Bees during the night's rest. An Ammophlla with red fore-legs {A. holosericea)'^ is plentiful In my enclosure to- wards the end of August and selects a certain lavender-border for her dormitory. At dusk, especially after a stifling day, when a storm is brewing, I am sure to find the strange sleeper settled there. Never was more eccentric attitude adopted for a night's rest! The mandibles bite right into the lavender-stem. Its square shape supplies a firmer hold than a round stalk would do. With this one and only prop, the animal's * Cf. The Hunting Wasps: chap. xiii. — Translator's Note. 202 The Empusa body juts out stiffly, at full length, with legs folded. It forms a right angle with the supporting axis, so much so that the whole weight of the insect, which has turned itself into the arm of a lever, rests upon the mandibles. The Ammophila sleeps extended in space by virtue of its mighty jaws. It takes an animal to think of a thing like that, which upsets all our preconceived ideas of repose. Should the threatening storm burst, should the stalk sway in the wind, the sleeper is not troubled by her swinging hammock; at most, she presses her fore-legs for a moment against the tossed mast. As soon as equilibrium is restored, the favourite posture, that of the horizontal lever, is resumed. Perhaps the mandibles, like the bird's toes, possess the faculty of gripping tighter in proportion to the rocking of the wind. The Ammophila is not the only one to sleep in this singular position, which is copied by many others — Anthidia,^ Odyneri,^ Eucerse ^ — and mainly by the males. All * Cotton-bees. Cf.

Some, the stouter species, allow themselves to rest the tip of their arched abdomen against the pole. This visit to the dormitory of certain Wasps and Bees does not explain the problem of the Empusa; it sets up another one, no less difficult. It shows us how deficient we are in insight, when it comes to differentiating between fatigue and rest in the cogs of the animal machine. The Ammophila, with the static paradox afforded by her mandibles; the Empusa, with her claws unwearied by ten months' hanging, leave the physiologist perplexed and make him wonder what really constitutes rest. In absolute fact, there is no rest, apart from that which puts an end to life. The struggle never ceases; some muscle is always toiling, some nerve strain- ing. Sleep, which resembles a return to the peace of non-existence, is, like waking, an effort, here of the leg, of the curled tail; there of the claw, of the jaws. The transformation is effected about the middle of May and the adult Empusa makes her appearance. She is even more remark- able in figure and attire than the Praying 204 The Empusa Mantis. Of her youthful eccentricities, she retains the pointed mitre, the saw-like arm- guards, the long bust, the knee-pieces, the three rows of scales on the lower surface of the belly; but the abdomen is now no longer twisted into a crook and the animal is comelier to look upon. Large pale-green wings, pink at the shoulder and swift in flight In both sexes, cover the belly, which is striped white and green underneath. The male, the dandy sex, adorns himself with plumed antennae, like those of certain Moths, the Bombyx tribe. In respect of size, he is almost the equal of his mate. Save for a few slight structural details, the Empusa is the Praying Mantis. The peasant confuses them. When, in spring, he meets the mitred Insect, he thinks he sees the common Prego-Dieu, who is a daughter of the autumn. Similar forms would seem to indicate similarity of habits. In fact, led away by the extraordinary armour, we should be tempted to attribute to the Em- pusa a mode of life even more atrocious than that of the Mantis. I myself thought so at first; and any one, relying upon false analogies, would think the same. It is a fresh error: for all her warlike aspect, the 205 The Life of the Grasshopper Empusa is a peaceful creature that hardly repays the trouble of rearing. Installed under the gauze bell, whether in assemblies of half-a-dozen or in separate couples, she at no time loses her placidity. Like the larva, she is very abstemious and contents herself with a Fly or two as her daily ration. Big eaters are naturally quarrelsome. The Mantis, bloated with Locusts, soon becomes irritated and shows fight. The Empusa, with her frugal meals, does not in- dulge in hostile demonstrations. There is no strife among neighbours nor any of those sudden unfurlings of the wings so dear to the Mantis when she assumes the spectral attitude and puffs like a startled Adder; never the least inclination for those cannibal banquets whereat the sister who has been worsted in the fight is devoured. Such atrocities are here unknown. Unknown also are tragic nuptials. The male is enterprising and assiduous and is sub- jected to a long trial before succeeding. For days and days, he worries his mate, who ends by yielding. Due decorum is preserved after the wedding. The feathered groom retires, respected by his bride, and does his little bit 206 The Empusa of hunting, without danger of being appre- hended and gobbled up. The two sexes hve together in peace and mutual indifference until the middle of July. Then the male, grown old and decrepit, takes counsel with himself, hunts no more, becomes shaky in his walk, creeps down from the lofty heights of the trellised dome and at last collapses on the ground. His end comes by a natural death. And remember that the other, the male of the Praying Mantis, ends in the stomach of his gluttonous spouse. The laying follows close upon the disap- pearance of the males. The Empusa, when about to build her nest, has not the round belly of the Praying Mantis, rendered heavy and inactive by her fertility. Her slender figure, still capable of flight, announces a scanty progeny. Her nest, fixed upon a straw, a tv/ig, a chip of stone, is quite as small a structure as that of the dwarf Mantis {Ameles decolor) and measures two-fifths of an inch, at most, in length. The general shape is that of a trapezoid, of which the shorter sides are, respectively, sloping and slightly convex. As a rule, the sloping side is surmounted by a thread-like appendage, similar to the final spur of the nests of the 207 The Life of the Grasshopper Mantis and the Ameles, but finer in appear- ance. This is the last drop of viscous matter, dried and drawn out. Builders, when their work is finished, crown the edifice with a green bough and coloured streamers. In much the same way, the Mantis tribe set up a ma;st on the completed nest. A very thin grey-wash, formed of dried foam, covers the Empusa's work, especially on the upper surface. Under this delicate glaze, which is easily rubbed off, the funda- mental substance appears, homogeneous, horny, pale-red. Six or seven hardly-per- ceptible furrows divide the sides into curved sections. After the hatching, a dozen round orifices open on the top of the building, in two alternate rows. These are the exit-doors for the young larvas. The slightly projecting rim is continued from each aperture to the next in a sort of ribbon with a double row of alternating loops. It is obvious that the windings of this ribbon are the result of an oscillating movement of the ovipositor in labour. Those exit-holes, so regular in shape and arrangement, completed by the lateral ribs of the nest, present the appear- ance of two dainty mouth-organs placed in 208 The Empusa juxtaposition. Each of them corresponds with a cell containing two eggs. The eggs in all, therefore, amount to about a couple of dozen. I have not seen the hatching. I do not know whether, as in the Praying Mantis, it is preceded by a transition-stage adapted to facilitate the delivery. It may easily be that there is nothing of the kind, since everything is so well-prepared for the exit. Above the cells is a very short exit-hall, free of any obstacle. It is closed merely by a small quantity of frothy, crumbly matter, which will readily yield to the mandibles of the new-born larvas. With this wide passage leading to the outer air, long legs and slender antennas cease to be embarrassing append- ages; and the tiny creature might well have the free use of them from the moment of leaving the egg, without going through the primary larval stage. Not having seen for myself, I merely mention the probable course of things. One word more on comparative manners. The Mantis goes in for battle and cannibal- ism; the Empusa is peaceable and respects her kind. To what cause are these profound moral differences due, when the organic 2oy The Life of the Grasshopper structure Is the same? Perhaps to the differ- ence of diet. FrugaHty, in fact, softens char- acter, in animals as in men; gross feeding brutahzes It. The gormandizer gorged with meat and strong drink, a fruitful source of savage outbursts, could not possess the gen- tleness of the ascetic who dips his bread into a cup of milk. The Mantis is that gorman- dizer, the Empusa that ascetic. Granted. But whence does the one derive her voracious appetite, the other her tem- perate ways, when It would seem as though their almost Identical structure ought to pro- duce an Identity of needs? These insects tell us, In their fashion, what many have already told us: that propensities and aptitudes do not depend exclusively upon anatomy; high above the physical laws that govern matter rise other laws that govern instincts. 210 CHAPTER XI THE WHITE-FACED DECTICUS : HIS HABITS ^TT^HE White-faced Decticus {D. albifrons, A Fabr.) stands at the head of the Grass- hopper clan in my district, both as a singer and as an insect of imposing presence. He has a grey costume, a pair of powerful mandibles and a broad ivory face. Without being plentiful, he does not let himself be sought in vain. In the height of summer we find him hopping in the long grass, especially at the foot of the sunny rocks where the turpentine-tree takes root. At the end of July I start a Decticus- menagerie. As a vivarium I adopt a big wire-gauze cover standing on a bed of sifted earth. The population numbers a dozen; and both sexes are equally represented. The question of victuals perplexes me for some time. It seems as though the regula- tion diet ought to be a vegetable one, to judge by the Locust, who consumes any 211 The Life of the Grasshopper green thing. I therefore offer my captives the tastiest and tenderest garden-stuff that my enclosure holds : leaves of lettuce, chicory and corn-salad. The Dectici scarcely touch it with a contemptuous tooth. It is not the food for them. Perhaps something tough would suit their strong mandibles better. I try various Graminaceae, including the glaucous panic- grass, the miaiico of the Provencal peasant, the Setaria glauca of the botanists, a weed that infests the fields after the harvest. The panic-grass is accepted by the hungry ones, but it is not the leaves that they devour : they attack only the ears, of which they crunch the still tender seeds with visible satisfaction. The food is found, at least for the time being. We shall see later. In the morning, when the rays of the sun visit the cage placed in the window of my study, I serve out the day's ration, a sheaf of green spikes of common grass picked outside my door. The Dectici come running up to the handful, gather round it and, very peaceably, without quarrelling among them- selves, dig with their mandibles between the bristles of the spikes to extract and nibble the unripe seeds. Their costume makes one 212 The White-faced Decticus: his Habits think of a flock of Guinea-fowl pecking the grain scattered by the farmer's wife. When the spikes are robbed of their tender seeds, the rest is scorned, however urgent the claims of hunger may be. To break the monotony of the diet as much as is possible in these dog-days, when every- thing is burnt up, I gather a thick-leaved, fleshy plant which is not too sensitive to the summer heat. This is the common purslane, another invader of our garden-beds. The new green stuff meets with a good reception; and once again the Dectici dig their teeth not into the leaves and the juicy stalks, but only into the swollen capsules of half-formed grains. This taste for tender seeds surprises me : drjuriKo?, biting, fond of biting, the lexicon tells us. A name that expresses nothing, a mere identification-number, is able to satisfy the nomenclator; in my opinion, If the name possesses a characteristic meaning and at the same time sounds well, it Is all the better for It. Such Is the case here. The Decticus is eminently an Insect given to biting. Mind your finger If the sturdy Grasshopper gets hold of It : he will rip It till the blood comes. And can this powerful jaw, of which I 213 The Life of the Grasshopper have to beware when I handle the creature, possess no other function than to chew soft grains? Can a mill like this have only to grind little unripe seeds? Something has escaped me. So well-armed with mandibular pincers, so well-endowed with masticatory muscles that swell out his cheeks, the Dec- tlcus must cut up some leathery prey. This time I find the real diet, the funda- mental if not the exclusive one. Some good- sized Locusts are let Into the cage. I put in it the species mentioned in a note below,^ now one, now the other, as they happen to get caught in my net. A few Grasshoppers ' are also accepted, but not so readily. There is every reason to think that, if I had had the luck to capture them, the entire Locust and Grasshopper family would have met the same fate, provided that they were not too insignificant in size. Any fresh meat tasting of Locust or Grasshopper suits my ogres. The most fre- quent victim is the Blue-winged Locust. * CEdipoda coerulescens, LiN. ; CE. miniata, Pallas; Sph'mgmzotns ccrulans, LiN. ; Caloptenus italicus, Lin.; Pachytyhis nigrofasciatus, DE Geer; Truxalis nasuta, Lin. — Author's Note.

This is how things happen : as soon as the game is introduced, an uproar ensues in the mess-room, especially if the Dectici have been fasting for some time. They stamp about and, hampered by their long shanks, dart forward clumsily; the Locusts make desperate bounds, rush to the top of the cage and there hang on, out of the reach of the Grasshopper, who is too stout to climb so high. Some are seized at once, as soon as they enter. The others, who have taken refuge up in the dome, are only postponing for a little v/hile the fate that awaits them. Their turn will come ; and that soon. Either because they are tired or be- cause they are tempted by the green stuff below, they will come down ; and the Dectici will be after them immediately. Speared by the hunter's fore-legs, the game is first wounded In the neck. It is al- ways there, behind the head, that the Lo- cust's shell cracks first of all; It Is always there that the Decticus probes persistently before releasing his hold and taking his sub- sequent meals off whatever joint he chooses. It Is a very judicious bite. The Locust Is hard to kill. Even v/hen beheaded, he goes 215 The Life of the Grasshopper on hopping. I have seen some who, though half-eaten, kick out desperately and suc- ceed, with a supreme effort, in releasing themselves and jumping away. In the brush- wood, that would be so much game lost. The Dectlcus seems to know all about It. To overcome his prey, so prompt to escape by means of its two powerful levers, and to render it helpless as quickly as possible, he first munches and extirpates the cervical ganglia, the main seat of Innervation. Is this an accident, In which the assassin's choice plays no part? No, for I see the murder performed invariably in the same way when the prey is in possession of its full strength; and again no, because, when the Locust Is offered In the form of a fresh corpse, or when he is weak, dying, incapable of de- fence, the attack is made anywhere, at the first spot that presents itself to the assailant's jaws. In such cases the Dectlcus begins either with a haunch, the favourite morsel, or with the belly, back or chest. The pre- liminary bite in the neck is reserved for difficult occasions. This Grasshopper, therefore, despite his dull Intellect, possesses the art of killing scientifically of which we have seen so many 216 The White-faced Dectlcus: his Habits instances elsewhere; * but with him it is a rude art, falling within the knacker's rather than the anatomist's domain. Two or three Blue-winged Locusts are none too many for a Decticus' daily ration. It all goes down, save the wings and wing- cases, which are disdained as too tough. In addition, there is a snack of tender millet- grains stolen every now and again to make a change from the banquet of game. They are big eaters, are my boarders; they sur- prise me with their gormandizing and even more with their easy change from an animal to a vegetable diet. With their accommodating and anything but particular stomachs, they could render some slight service to agriculture, if there were more of them. They destroy the Lo- custs, many of whom, even in our fields, are of ill fame ; and they nibble, amid the unripe corn, the seeds of a number of plants which are obnoxious to the husbandman. But the Decticus' claim to the honours of the vivarium rests upon something much better than his feeble assistance in preserving the fruits of the earth : in his song, his nup- ^ Cf.

How did the insect's ancestors live, in the palaeozoic age? They had their crude and uncouth side, banished from the better- proportioned fauna of to-day; we catch a vague glimpse of habits now almost out of use. It is unfortunate for our curiosity that the fossil remains are silent on this mag- nificent subject. Luckily we have one resource left, that of consulting the successors of the prehistoric insects. There is reason to believe that the Locustids ^ of our own period have retained an echo of the ancient customs and can tell us something of the manners of olden time. Let us begin by questioning the Dectlcus. In the vivarium the sated herd are lying on their bellies in the sun and blissfully digesting their food, giving no other sign of life than a gentle swaying of the antennas. It is the hour of the after-dinner nap, the hour of enervating heat. From time to time a male gets up, strolls solemnly about, raises his wing-cases slightly and utters an occa- * An orthopterous family which includes the Grass- hoppers, but not the Locusts. The latter are Acridians. — Translator's Note. 2i8 The White-faced Decticus: his Habits sional tick-tick. Then he becomes more animated, hurries the pace of his tune and ends by grinding out the finest piece in his repertoire. Is he celebrating his wedding? Is his song an epithalamium? I will make no such state- ment, for his success is poor if he is really making an appeal to his fair neighbours. Not one of his group of hearers gives a sign of attention. Not a female stirs, not one moves from her comfortable place in the sun. Sometimes the solo becomes a concerted piece sung by two or three in chorus. The multiple invitation succeeds no better. True, their impassive ivory faces give no indication of their real feelings. If the suitors' ditty indeed exercises any sort of seduction, no outward sign betrays the fact. According to all appearances, the clicking is addressed to heedless ears. It rises in a passionate crescendo until it becomes a con- tinuous rattle. It ceases when the sun vanishes behind a cloud and starts afresh when the sun shows itself again ; but it leaves the ladies indifferent. She who was lying with her shanks out- stretched on the blazing sand does not change her position; her antennary threads 219 The Life of the Grasshopper give not a quiver more and not a quiver less; she who was gnawing the remains of a Lo- cust does not let go the morsel, does not lose a mouthful. To look at those heartless ones, you would really say that the singer was making a noise for the mere pleasure of feeling himself alive. It Is a very different matter when, towards the end of August, I w^Itness the start of the wedding. The couple finds itself standing face to face quite casually, without any lyrical prelude whatever. Motionless, as though turned to stone, with their foreheads almost touching, the two exchange caresses with their long antennae, fine as hairs. The male seems somewhat preoccupied. He washes his tarsi; with the tips of his mandi- bles he tickles the soles of his feet. From time to time he gives a stroke of the bow: tick; no more. Yet one would think that this was the very moment at which to make the most of his strong points. Why not declare his flame In a fond couplet, Instead of standing there, scratching his feet? Not a bit of It. He remains silent In front of the coveted bride, herself Impassive. The Interview, a mere exchange of greet- 220 The White-faced Decticus: his Habits ings betv/een friends of different sexes, does not last long. What do they say to each other, forehead to forehead? Not much, apparently, for soon they separate with nothing further; and each goes his way where he pleases. Next day, the same two meet again. This time, the song, though still very brief, is in a louder key than on the day before, while being still very far from the burst of sound to which the Decticus will give utterance long before the pairing. For the rest, it is a repetition of what I saw yesterday: mutual caresses with the antennas, which limply pat the well-rounded sides. The male does not seem greatly enrap- tured. He again nibbles his foot and seems to be reflecting. Alluring though the enter- prise may be, It Is perhaps not unattended with danger. Can there be a nuptial tragedy here, similar to that which the Praying Mantis has shown us? Can the business be exceptionally grave ? Have patience and you shall see. For the moment, nothing more happens. A few days later, a little light Is thrown upon the subject. The male Is underneath, lying flat on the sand and towered over by 221 The Life of the Grasshopper his powerful spouse, who, with her sabre exposed, standing high on her hind-legs, over- whelms him with her embrace. No, indeed: in this posture the poor Decticus has nothing of the victor about him ! The other, brutally, without respecting the musical-box, is forcing open his wing-cases and nibbling his flesh just where the belly begins. Which of the two takes the initiative here? Have not the parts been reversed? She who is usually provoked is now the pro- voker, employing rude caresses capable of carrying off the morsel touched. She has not yielded to him; she has thrust herself upon him, disturbingly, imperiously. He, lying flat on the ground, quivers and starts, seems try- ing to resist. What outrageous thing is about to happen? I shall not know to-day. The floored male releases himself and runs away. But this time, at last, we have it. Master Decticus Is on the ground, tumbled over on his back. Hoisted to the full height of her shanks, the other, holding her sabre almost perpendicular, covers her prostrate mate from a distance. The two ventral extremities curve Into a hook, seek each other, meet; and soon from the male's convulsive loins there 222 The White-faced Decticus: his Habits is seen to issue, in painful labour, something monstrous and unheard-of, as though the creature were expelling its entrails in a lump. It is an opalescent bag, similar in size and colour to a mistletoe-berry, a bag with four pockets marked off by faint grooves, two larger ones above and two smaller ones below. In certain cases the number of cells increases and the whole assumes the appear- ance of a packet of eggs such as Helix aspersa, the Common Snail, lays in the ground. The strange concern remains hanging from the lower end of the sabre of the future mother, who solemnly retires with the ex- traordinary wallet, the spermatophore, as the physiologists call it, the source of life for the ovules, in other words the cruet which will now in due course transmit to the proper place the necessary complement for the evo- lution of the germs. A capsule of this kind is a rare, an in- finitely rare thing in the world of to-day. So far as I know, the Cephalopods ^ and the Scolopendras ^ are, In our time, the only * The class of molluscs containing the Squids, Cuttle- fish, Octopus, etc. — Translator's Note. ^ A genus of Myriapods including the typical Centi- pedes.— Translator's Note. 223 The Life of the Grasshopper other annuals that make use of the queer apparatus. Now Octopuses and Millepedes date back to the earliest ages. The Dectlcus, another representative of the old world, seems to tell us that what is a curious ex- ception now might well have been a more or less general rule originally, all the more so as we shall come upon similar Incidents in the case of the other Grasshoppers. When the male has recovered from his shock, he shakes the dust off himself and once more begins his merry click-clack. For the present let us leave him to his joys and follow the mother that is to be, pacing along solemnly with her burden, which is fastened with a plug of jelly as transparent as glass. At intervals she draws herself up on her shanks, curls Into a ring and seizes her opalescent load In her mandibles, nibbling It calmly and squeezing It, but without tearing the wrapper or shedding any of the contents. Each time, she removes from the surface a particle which she chews and then chews again slowly, ending by swallowing It. This process Is continued for twenty minutes or so. Then the capsule, now drained. Is torn off in a single piece, all but the jelly plug at the end. The huge, sticky 224 The White-faced Decticus: his Habits mass is not let go for a moment, but is munched, ground and kneaded by the insect's mandibles and at last gulped down whole. At first I looked upon the horrible banquet as no more than an individual aberration, an accident: the Decticus' behaviour was so ex- traordinary; no other instance of it was known to me. But I have had to yield to the evidence of the facts. Four times in success- ion I surprised my captives dragging their wallet and four times I saw them soon tear it, work at it solemnly with their mandibles for hours on end and finally gulp it down. It is therefore the rule : when its contents have reached their destination, the fertilizing capsule, possibly a powerful stimulant, an unparalleled dainty, is chewed, enjoyed and swallowed. If this, as we are entitled to believe, Is a relic of ancient manners, we must admit that the Insect of old had singular customs. Reaumur tells us of the startling operations of the Dragon-flies when pairing. This again Is a nuptial eccentricity of primeval times. When the Decticus has finished her strange feast, the end of the apparatus still remains In Its place, the end whose most visible 225 The Life of the Grasshopper part consists of two crystalline nipples the size of pepper-corns. To rid itself of this plug, the insect assumes a curious attitude. The ovipositor is driven half-way into the earth, perpendicularly. That will be the prop. The long hind-legs straighten out, raise the creature as high as possible and form a tripod with the sabre. Then the insect again curves itself into a complete circle and, with its mandibles, crumbles to atoms the end of the apparatus, consisting of a plug of clearest jelly. All these remnants are scrupulously swallowed. Not a scrap must be lost. Lastly, the ovipositor is washed, wiped, smoothed with the tips of the palpi. Everything Is put In order again; nothing remains of the cum- brous load. The normal pose Is resumed and the Dectlcus goes back to pilfering the ears of millet. To return to the male. Limp and ex- hausted, as though shattered by his exploit, he remains where he Is, all shrivelled and shrunk. He Is so motionless that I believe him dead. Not a bit of It! The gallant fellow recovers his spirits, picks himself up, polishes himself and goes off. A quarter of an hour later, when he has taken a fewmouth- 226 The White-faced Decticus: his Habits fuls, behold him stridulating once more. The tune is certainly lacking in spirit. It is far from being as brilliant or prolonged as it was before the wedding; but, after all, the poor old crock is doing his best. Can he have any further amorous pre- tensions? It is hardly hkely. Affairs of that kind, calling for ruinous expenditure, are not to be repeated : it would be too much for the works of the organism. Neverthe- less, next day and every day after, when a diet of Locusts has duly renewed his strength, the Decticus scrapes his bow as noisily as ever. He might be a novice, Instead of a glutted veteran. His persistence surprises me. If he be really singing to attract the atten- tion of his fair neighbours, what would he do with a second wife, he who has just extracted from his paunch a monstrous wallet in which all life's savings were accumulated? He is thoroughly used up. No, once more, in the big Grasshopper these things are too costly to be done all over again. To-day's song, despite its gladness, Is certainly no epl- thalamlum. And, If you watch him closely, you will see that the singer no longer responds to the 227 The Life of the Grasshopper teasing of the passers' antennae. The ditties become fainter from day to day and occur less frequently. In a fortnight the insect is dumb. The dulcimer no longer sounds, for lack of vigour in the player. At last the decrepit Decticus, who now scarcely touches food, seeks a peaceful re- treat, sinks to the ground exhausted, stretches out his shanks in a last throe and dies. As it happens, the widow passes that way, sees the deceased and, breathing eternal remembrance, gnaws off one of his thighs. The Green Grasshopper behaves similarly. A couple isolated in a cage are subjected to a special watch. I am present at the end of the pairing, when the future mother is carry- ing, fixed to the point of her sword, the pretty raspberry which will occupy our atten- tion later. ^ Debilitated by recent happen- ings, the male at this moment is mute. Next day, his strength returns; and you hear him sinking as ardently as ever. He stridulates while the mother is scattering her eggs over the ground; he goes on making a noise long after the laying is done and when nothing more is wanted to perpetuate the race. * Cf. Chapter XIV. of the present volume. — Translator's Note. 228 The White-faced Decticus: his Habits It is quite clear that this persistent singing has not an amorous appeal for its object: by this time, all of that is over, quite over. Lastly, one day or another, life fails and the instrument is dumb. The eager singer is no more. The survivor gives him a funeral copied from that of the Decticus : she de- vours the best bits of him. She loved him so much that she had to eat him up. These cannibal habits recur in most of the Grasshopper tribe, without however equal- ling the atrocities of the Praying Mantis, who treats her lovers as dead game while they are still full of life. The Decticus m.other, the Green Grasshopper and the rest at least wait until the poor wretches are dead. I will except the Ephlpplger, who Is so meek In appearance. In my cage, when laylng-tlme Is at hand, she has no scruples about taking a bite at her companions, without possessing the excuse of hunger. Most of the males end m this lamentable fashion, half-devoured. The mutilated victim protests; he would rather, he could indeed go on living. Having no other means of defence, he produces with his bow a few grating sounds which this time decidedly are not a nuptial song. Dying with a great hole in his belly, he utters his 229 The Life of the Grasshopper plaint in a like manner as though he were rejoicing In the sun. His Instrument strikes the same note whether it express sorrow or gladness. 230 CHAPTER XII THE WHITE-FACED DECTICUS : THE LAYING AND THE HATCHING OF THE EGGS THE White-faced Decticus is an African insect that in France hardly ventures beyond the borders of Provence and Langue- doc. She wants the sun that ripens the oHves. Can it be that a high temperature acts as a stimulus to her matrimonial eccen- tricities, or are we to look upon these as family customs, independent of climate ? Do things happen under frosty skies just as they do under a burning sun? I go for my information to another Decticus, the Alpine Analota {A. alpina, Yersin), who inhabits the high ridges of Mont Ventoux,^ which are covered with snow for half the year. Many a time, during my old botanical expeditions, I had noticed the * The highest mountain (6,270 feet) in the neighbour- hood of Serignan. Cf. The Hunting IV asps: chap. xi. — Translator's Note. 231 The Life of the Grasshopper portly Insect hopping among the stones from one bit of turf to the next. This time, I do not go in search of It : It reaches me by post. Following my Indications, an obliging forester ^ climbs up there twice In the first fortnight of August and brings me back the wherewithal to fill a cage comfortably. In shape and colouring it Is a curious specimen of the Grasshopper family. Satin- ; white underneath, It has the upper part I sometimes olive-black, sometimes bright- green or pale-brown. The organs of flight , are reduced to mere vestiges. The female has as wing-cases two short white scales, j some distance apart; the male shelters under the edge of his corselet two little concave plates, also w^hlte, but laid one on top of the other, the left on the right. These two tiny cupolas, with bow and sounding-board, rather suggest, on a smaller scale, the musical Instrument of the Ephlp- plger, whom the mountain Insect resembles to some extent In general appearance. I do not know what sort of tune cymbals so small as these can produce. I do not remember ever hearing them In their native ^ M.

Though they lead a joyous hfe, my captives are always dumb. The exiles do not seem greatly to regret their cold peaks, among the orange poppies and saxifrages of arctic climes. What used they to browse upon up there? The Alpine meadow-grass, Mont-Cenis violets, Alll- oni's bell-flower? I do not know. In the absence of Alpine grasses, I give them the common endive from my garden. They accept It without hesitation. They also accept such Locusts as can offer only a feeble resistance; and the diet alter- nates between animal and vegetable fare. They even practise cannibalism. If one of my Alpine visitors limps and drags a leg, the others eat him up. So far I have seen no- thing striking: these are the usual Grass- hopper manners. The Interesting sight Is the pairing, which occurs suddenly, without any prelude. The meeting takes place sometimes on the ground, sometimes on the wirework of the cage. In the latter case, the sword-bearer, firmly hooked to the trellis, supports the whole weight of the couple. The other is back 233 The Life of the Grasshopper downwards, his head pointing to his mate's tall. With his long, fleshy-shanked hind- legs, he gets a grip of her sides; with his four front legs, often also with his mandibles, he grasps and squeezes the sabre, which pro- jects slantwise. Thus hanging to this sort of greased pole, he operates in space. When the meeting takes place on the ground, the couple occupy the same position, only the male Is lying on his back in the sand. In both cases the result is an opal grain which, in the visible part of it, resembles In shape and size the swollen end of a grape-pip. As soon as this object is In position, the male decamps at full speed. Can he be In danger? Possibly, to judge from what I have seen. I admit that I have seen it only once. The bride in this case was grappling with two rivals. One of them, hanging to the sabre, was at work in due form behind; the other, in front, tightly clawed and with his belly ripped open, was waving his limbs In vain protest against the harpy crunching him impassively In small mouthfuls. I had before my eyes, under even more atrocious condi- tions, the horrors which the Praying Mantis had shown me in the old days: unbridled 234 The White-faced Decticus: the Eggs rut; carnage and voluptuousness in one; a reminiscence perhaps of ancient savagery. As a rule, the male, a dwarf by comparison with the female, hastens to run away as soon as his task is consummated. The deserted one makes no movement. Then, after wait- ing twenty minutes or so, she curves herself into a ring and proceeds to enjoy the final banquet. She pulls the sticky raisin-pip into shreds which are chewed with grave appre- ciation and then gulped down. It takes her more than an hour to sw^allow the thing. When not a crumb remains, she descends from the wire gauze and mingles with the herd. Her eggs will be laid in a day or two. The proof is established. The matri- monial habits of the White-faced Decticus are not an exception due to the heat of the climate : the Grasshopper from the cold peaks shares them and surpasses them. We will return to the big Decticus with the ivory face. The laying follows close upon the strange events which we have de- scribed. It is done piecemeal, as the ovaries ripen. Firmly planted on her six legs, the mother bends her abdomen into a semicircle and drives her sabre perpendicularly into the 235 The Life of the Grasshopper soil, which, consisting in my cages of sifted earth, presents no serious resistance. The ovipositor therefore descends without hesita- tion and enters up to the hilt, that is to say, to a depth of about an Inch. For nearly fifteen minutes, absolute Im- mobility. This Is the time when the eggs are being laid. At last the sabre comes up a little way and the abdomen swings briskly from side to side, communicating an alter- nate transversal movement to the Implement. This tends to scrape out and widen the sunken hole; It also has the effect of releasing from the walls earthy materials which fill up the bottom of the cavity. Thereupon the ovipositor, which Is half In and half out, rams down this dust. It comes up a short distance and then dips repeatedly, with a sudden, jerky movement. We should work In the same way with a stick to ram down the earth In a perpendicular hole. Thus alternating the transversal swing of the sabre with the blows of the rammer, the mother covers up the well pretty quickly. The external traces of the work have still to be done away with. The Insect's legs, which I expected to see brought Into play, remain Inactive and keep the position 236 The White-faced Decticus: the Eggs adopted for laying the eggs. The sabre alone scratches, sweeps and smooths the ground with its point, very clumsily, it must be admitted. Now all is in order. The abdomen and the ovipositor are restored to their normal positions. The mother allows herself a mo- ment's rest and goes to take a turn in the neighbourhood. Soon she comes back to the site vv^here she has already laid her eggs and, very near the original spot, which she recognizes clearly, she drives in her tool afresh. The same proceedings as before are repeated. Follow another rest, another exploration of the vicinity, another return to the place already sown. For the third time the pointed stake descends, only a very slight distance away from the previous hole. During the brief hour that I am watching her, I see her resume her laying five times, after breaking off to take a little stroll in the neighbour- hood; and the points selected are always very close together. On the following days, at varying inter- vals, the sowing is renewed for a certain number of times which I am not able to state exactly. In the case of each of these partial 237 The Life of the Grasshopper layings, the site changes, now here, now there, as this or that spot Is deemed the more propitious. When everything Is finished, I examine the little pits In which the Dectlcus placed her \ eggs. There are no packets In a foamy | sheath, such as the Locust supplies; no cells j either. The eggs He singly, without any pro- tection. I gather three score as the total product of one mother. They are of a pale j lilac-grey and are drawn out shuttlewlse, In j a narrow ellipsoid five or six millimetres I long.^ . . i The same isolation marks those of the Grey Dectlcus, which are black; those of the Vine Ephlpplger, which are ashen-grey; and those of the Alpine Analota, which are pale- lilac. The eggs of the Green Grasshopper, | which are a very dark olive-brown and, like those of the White-faced Dectlcus, about j sixty In number, are sometimes arranged * singly and sometimes stuck together In little clusters. These different examples show^ us that the Grasshoppers plant with a dibble. Instead of packing their seeds In little casks of hardened foam, like the Locusts, they put * .195 to .234 inch. — Translator's Note. 238 The White-faced Decticus: the Eggs them into the earth one by one or in very small clusters. The hatching is worth examination; I will explain why presently. I therefore gather plenty of eggs of the big Decticus at the end of August and place them in a small glass jar with a layer of sand. Without under- going any apparent modification, they spend eight months here under cover, sheltered from the frosts, the showers and the over- powering heat of the sun that would await them under natural conditions. When June comes, I often meet young Dectici in the fields. Some are already half their adult size, which is evidence of an early appearance dating back to the first fine days of the year. Nevertheless my jar shows no signs of any imminent hatching. I find the eggs just as I gathered them nine months ago, neither wrinkled nor tarnished, wear- ing, on the contrary, a most healthy look. What causes this indefinitely prolonged de- lay? A suspicion occurs to me. The eggs of the Grasshopper tribe are planted in the earth like seeds. They are there exposed, without any kind of protection, to the watery influence of the snow and the rain. Those 239 The Life of the Grasshopper in my jar have spent two-thirds of the year in a state of comparative dryness. Perhaps, in order to hatch, they lack what grain abso- lutely needs in order to sprout. Animal seeds as they are, they may yet require under earth the moisture necessary to vegetable seeds. Let us try. I place at the bottom of somiC glass tubes, to enable me to make certain observations which I have in mind, a pinch of backward eggs taken from my collection; and on the top I heap lightly a layer of very fine, damp sand. The receptacle is closed with a plug of wet cotton, which will maintain a constant moisture in the interior. The column of sand measures about an inch, which is very much the depth at which the ovi- positor places the eggs. Any one seeing my preparations and unacquainted with their ob- ject would hardly suspect them of being in- cubators; he would be more likely to think them the apparatus of a botanist who was experimenting with seeds. My anticipation was correct. Favoured by the high temperature of the summer solstice, the Grasshopper seed does not take long to sprout. The eggs swell; the front end of each Is spotted with two dark dots, 240 The White-faced Decticus: the Eggs the rudiments of the eyes. It is quite evi- dent that the bursting of the shell is near at hand. I spend a fortnight in keeping a tedious watch at every hour of the day: I have to surprise the young Decticus actually leaving the egg, If I want to solve a question that has long been vexing my mind. The quest- Ion Is this : the Grasshopper's egg Is burled at a varying depth, according to the length of the ovipositor or dibble. An inch is about the most for the seeds of the best- equipped Insects in our parts. Now the new- born Decticus, hopping awkwardly in the grass at the approach of summer, is, like the adult, endowed with a pair of very long tentacles, vying with hairs for slenderness; he carries behind him two extraordinary legs, two enormous hinged levers, a pair of jumping-stllts that would be very Incon- venient for ordinary walking. How does the feeble little creature set to work, with this cumbrous luggage, to emerge from the earth? By what artijfice does It manage to clear a passage through the rough soil? With its antennary plumes, which an atom of sand can break, with its immense shanks, which the least effort is enough to 241 The Life of the Grasshopper disjoint, the mite is obviously incapable of reaching the surface and freeing itself. The miner going underground puts on a protective dress. The little Grasshopper also, making a hole in the earth in the oppo- site direction, must don an overall for emer- ging from the earth; he must possess a simpler, more compact transition-form, which enables him to come out through the sand, a delivery-shape analogous to that which the Cicada and the Praying Mantis use at the moment of issuing, one from his twig, the other from the labyrinth of his nest. Reality and logic here agree. The Dec- ticus. In point of fact, does not leave the egg in the form in which I see him, the day after his birth, hopping on the lawn; he possesses a temporary structure better-suited to the dif- ficulties of the emergence. Coloured a deli- cate flesh-white, the tiny creature is cased in a scabbard which keeps the six legs flattened against the abdomen, stretching backwards, inert. In order to slip more easily under the ground, he has his shanks tied up beside his body. The antennas, those other Irksome appendages, are motionless, pressed against the parcel. The head is very much bent against the 242 The White-faced Decticus: the Eggs chest. With its big, black ocular specks and its undecided and rather bloated mask, it suggests a diver's helmet. The neck opens wide at the back and, with a slow throbbing, by turns swells and subsides. That is the motor. The new-born insect moves along with the aid of its occipital hernia. When uninflated, the fore-part pushes back the damp sand a little way and slips into it by digging a tiny pit; then, blown out, it be- comes a knob, which moulds itself and finds a support in the depression obtained. Then the rear-end contracts; and this gives a step forward. Each thrust of the locomotive blister means nearly a millimetre ^ traversed. It is pitiful to see this budding flesh, scarcely tinged with pink, knocking with its dropsical neck and ramming the rough soil. The animal glair, not yet quite hardened, struggles painfully with stone; and its efforts are so well directed that, in the space of a morning, a gallery opens, either straight or winding, an inch long and as wide as an average straw. In this way the harassed insect reaches the surface. Half-caught in its exit-shaft, the disin- terred one halts, waits for its strength to * .039 inch. — Translator's Note. 243 The Life of the Grasshopper return and then for the last time swells its occipital hernia as far as it will go and bursts the sheath that has protected it so far. The creature throws off its miner's overall. Here at last is the Decticus in his youthful shape, quite pale still, but darker the next day and a regular blackamoor compared with the adult. As a prelude to the ivory face of a riper age, he sports a narrow white stripe under his hinder thighs. Little Decticus, hatched before my eyes, life opens for you very harshly! Many of your kindred must die of exhaustion before attaining their freedom. In my tubes I see numbers who, stopped by a grain of sand, succumb half-way and become furred with a sort of silky mildev/. The mouldy part soon absorbs their poor little remains. When per- formed without my assistance, the coming to the light of day must be attended with even greater dangers. The usual soil is coarse and baked by the sun. Without a fall of rain, how do they manage, these immured ones? More fortunate in my tubes with their sifted and wetted mould, here you are out- side, you little white-striped nigger; you bite at the lettuce-leaf which I have given 244 The White-faced Decticus: the Eggs you; you leap about gaily in the cage where I have housed you. It would be easy to rear you, I can see, but it would not give me much fresh information. Let us then part com- pany. I restore you to liberty. In return for w^hat you have taught me, I bestow upon you the grass and the Locusts in the garden. Thanks to you, I know that Grasshoppers, in order to leave the ground in which the eggs are laid, possess a provisional shape, a primary larval stage, which keeps those too cumbrous parts, the long legs and antennae, swathed in a common sheath; I know that this sort of mummy, fit only to lengthen and shorten itself a little, has for an organ of locomotion a hernia in the neck, a throbbing blister, an original piece of mechanism which I have never seen used elsewhere as an aid to progression.^ * This essay was written prior to that on the Grey Flesh-flies, who employ a sinnilar method.

The sculptor uses form and imitates its perfection in so far as the chisel is able to imitate life. The draughtsman, likewise a copyist, seeks in black and white to give the illusion of relief on a flat surface. To the difficulties of draw- ing the painter adds those of colour, which are no less great. An inexhaustible model sits to all three. Rich though the painter's palette be, it will always be inferior to that of reality. Nor will the sculptor's chisel ever exhaust the treasures of the plastic art in nature. Form and colour, beauty of outline and play of light : these are all taught by the contempla- tion of actual things. They are imitated, 246 The Decticus: his Instrument they are combined according to our tastes, but they are not invented. On the other hand, our music has no pro- totype in the symphony of created things. Certainly there is no lack of sounds, faint or loud, sweet and solemn. The wind roaring through the storm-tossed woods, the waves curling and breaking on the beach, the thunder growling in the echoing clouds stir us with their majestic notes; the breeze filtering through the tiny foliage of the pine- trees, the Bees humming over the spring flowers charm every ear endowed with any delicacy; but these are monotonous noises, with no connection. Nature has superb sounds ; she has no music. Howling, braying, grunting, neighing, bel- lowing, bleating, yelping: these exhaust the phonetics of our near neighbours in organ- ization. A musical score composed of such elements would be called a hullabaloo. Man, forming a striking exception at the top of the scale of these makers of raucous noises, took it into his head to sing. An attribute which no other shares with him, the at- tribute of coordinated sounds whence springs the Incomparable gift of speech, led him on to scientific vocal exercises. In the absence 247 The Life of the Grasshopper of a model, It must have been a laborious apprenticeship. When our prehistoric ancestor, to cele- brate his return from hunting the Mammoth, Intoxicated himself with sour tipple brewed from raspberries and sloes, what can have Issued from his hoarse larynx? An orthodox melody? Certainly not; hoarse shouts, rather, capable of shaking the roof of his cave. The loudness of the cry constituted Its merit. The primitive song Is found to this day when men's throats are fired in taverns instead of caverns. And this tenor, with his crude vocal efforts, was already an adept at guiding his pointed flint to engrave on ivory the effigy of the monstrous animal which he had captured; he knew how to embellish his Idol's cheeks with red chalk; he knew how to paint his own face with coloured grease. There were plenty of models for form and colour but none for rhythmic sounds. With progress came the musical Instru- ment, as an adjunct to those first guttural at- tempts. Men blew down tubes taken all in one piece from the sappy branches; they pro- duced sounds from the barley-stalks and made whistles out of reeds. The shell of a 248 The Decticus: his Instrument Snail, held between two fingers of the closed list, imitated the Partridge's call; a trumpet formed of a wide strip of bark rolled into a horn reproduced the bellowing of the Bull; a few gut-strings stretched across the empty shell of a calabash grated out the first notes of our stringed instruments; a Goat's blad- der, fixed on a solid frame, was the original drum; two flat pebbles struck together at measured intervals led the way for the click of the castagnettes. Such must have been the primitive musical materials, materials still preserved by the child, which, with its simplicity in things artistic, is so strongly reminiscent of the big child of yore. Classical antiquity knew no others, as wit- ness the shepherds of Theocritus and Virgil. Sihestreni tenui miisam meditaris avena, says Meliboeus to Tityrus.^ * ** Beneath the shade which beechen boughs diffuse, You, Tityrus, entertain your sylvan muse. These blessings friend, a deity bestowed: He gave my kine to graze the flowery plain And to my pipe renewed the rural strain." — Pastorals: book i. ; Dryden's translation. 249 The Life of the Grasshopper What are we to make of this oat-straw, this frail shepherd's pipe, as they used to make us translate It In my young days? Did the poet write avena tenui by way of a rhetorical figure, or was he describing a reality? I vote for the reality, having my- self In the old days heard a concert of shep- herd's pipes. It was in Corsica, at Ajacclo. In gratitude for a handful of sugar-plums, some small boys of the neighbourhood came one day and serenaded me. Quite unexpectedly, in gusts of untutored harmony, strange sounds of rare sweetness reached my ears. I ran to the Vvindow. There stood the orchestra, none taller than a jack-boot, gathered sol- emnly In a ring, with the leader in the middle. Most of them had at their lips a green onion- stem, distended splndlewlse; others a stubble straw, a bit of reed not yet hardened by maturity. They blew into these, or rather they sang a vocero, to a grave measure, perhaps a relic of the Greeks. Certainly, It was not music as we understand it; still less was it a m.eaningless noise; but it was a vague, un- dulating melody, abounding In artless irregu- larities, a medley of pretty sounds in which 250 The Decticus: his Instrument the sibilations of the straw threw Into relief the bleating of the swollen stalks. I stood amazed at the onion-stem symphony. Very much so must the shepherds of the eclogue have gone to work, avena tenui; very much so must the bridal epithalamium have been sung in the Reindeer period. Yes, the simple melody of my Corslcan youngsters, a real humming of Bees on the rosemaries, has left a lasting trace In my memory. I can hear It now. It taught me the value of the rustic pipes, once so con- stantly celebrated In a literature that Is now old-fashioned. How far removed are we from those simple joys! To charm the populace in these days you need ophlcleides, saxhorns, trombones, cornets, every Imagina- ble sort of brass, with big drums and little drums and, to beat time, a gun-shot. That's what progress does. Three-and-twenty centuries ago, Greece assembled at Delphi for the festivals of the sun, Phoebus with the golden locks. Thrilled with religious emotion she listened to the Hymn of Apollo, a melody of a few lines, barely supported here and there by a scanty chord on the flute and cithara. Hailed as a masterpiece, the sacred song was engraved 251 The Life of the Grasshopper on marble tablets which the archaeologists have recently exhumed. The venerable strains, the oldest in musical records, have been heard in my time in the ancient theatre at Orange, a ruin in stone worthy of that ruin of sound. I was not present at the performance, being kept away by my habit of running to the west whenever there are fireworks in the east. One of my friends, a man gifted with a very sensitive ear, went; and he said to me afterwards : " There were probably ten thousand people forming the audience in the enormous amphitheatre. I very much doubt whether one of them understood that music of an- other age. As for me, I felt as if I were listening to a blind man's plaintive ditty and I looked round involuntarily for the dog holding the cup." The barbarian, to turn the Greek master- piece into a stupid wail ! Was it irreverence on his part? No, but it was incapacity. His ear, trained in accordance with other rules, was unable to take pleasure in artless sounds which had become strange and even disagree- able owing to their great age. What my friend lacked, what we all lack is the per- 252 The Decticus: his Instrument ceptlon of those primitive niceties which have been stifled by the centuries. To enjoy the Hymn to Apollo, we should have to go back to the simplicity of soul which one day made me think the buzzing of the onion- stalks delightful. And that we shall never do. But, if our music need not draw its in- spiration from the Delphic marbles, our statuary and our architecture will always find models of incomparable perfection in the work of the Greeks. The art of sounds, having no prototype imposed on it by na- tural facts, is liable to change : with our fickle tastes, that which is perfect in music to-day becomes vulgar and commonplace to- morrow. The art of forms, on the con- trary, being based on the immutable founda- tion of reality, always sees the beautiful where previous centuries saw it. There is no musical type anywhere, not even in the song of the Nightingale, cele- brated by Buffon ^ In grandiloquent terms. * Georges Louis Leclerc de Buffon (1707-1788), the foremost French naturalist and one of the foremost French writers, though his style, as Fabre rightly sug- gests, was nothing less than pompous. He was the originator, in the speech delivered at his reception into the French academy, of the famous aphorism, " Le style est I'homme meme." — Translator's Note. 253 The Life of the Grasshopper I have no wish to shock anybody; but why should I not give my opinion? Buffon's style and the Nightingale's song both leave me cold. The first has too much rhetoric about it and not enough sincere emotion. The second, a magnificent jewel-case of ill- assorted pearls of sound, makes so slight an appeal to the soul that a penny jug, filled with water and furnished with a whistle, will enable the lips of a child to reproduce the celebrated songster's finest trills. A little earthenware machine, warbling at the play- er's will, rivals the Nightingale. Above the bird, that glorious production of a vibrating air-column, creatures roar and bray and grunt, until we come to man, who alone speaks and really sings. Below the bird, they croak or are silent. The bellows of the lungs have two efflorescences se- parated by enormous empty spaces filled with formless sounds. Lower down still is the insect, which is much earlier in date. This first-born of the dwellers on the earth is also the first singer. Deprived of the breath which could set the vocal cords vibrating, it invents the bow and friction, of which man is later to make such wonderful use. Various Beetles produce a noise by sliding 254 The Decticus: his Instrument one rugged surface over another. The Capricorn moves his corseleted segment over its junction with the rest of the thorax; the Pine Cockchafer/ with his great fan- shaped antennae, rubs his last dorsal seg- ment with the edge of his wing-cases; the Copris" and many more know no other method. To tell the truth, these scrapers do not produce a musical sound, but rather a creaking like that of a weathercock on its rusty pin, a thin, sharp sound with no resonance in it. Among these inexperienced scrapers, I will select the Bolboceras (B. ^alliens, MuLS.),'^ as deserving honourable mention. Round as a ball, sporting a horn on his forehead, like the Spanish Copris, whose stercoral tastes he does not share, this pretty Beetle loves the pine-woods In my neighbourhood and digs himself a burrow in the sand, leaving it In the evening twilight with the gentle chirp of a well-fed nestling under Its mother's * Cf.

Though habitually silent, he makes a noise at the least disturbance. A dozen of him imprisoned in a box will provide you with a delightful symphony, very faint, it is true : you have to hold the box close to your ear to hear it. Compared with him, the Capricorn, Copris, Pine Cockchafer and the rest are rustic fiddlers. In their case, after all, it is not singing, but rather an expression of fear, I might almost say, a cry of anguish, a moan. The insect utters it only in a mo- ment of danger and never, so far as I know, at the time of its wedding. The real musician, who expresses his glad- ness by strokes of the bow and cymbals, dates much farther back. He preceded the insects endowed with a superior organiza- tion, the Beetle, the Bee, the Fly, the But- terfly, who prove their higher rank by com- plete transformations; he is closely connected with the rude beginnings of the geological period. The singing insect, in fact, belongs exclusively either to the order of the Hemip- tera, including the Cicads, or to that of the Orthoptera, including the Grasshoppers and Crickets. Its incomplete metamorphoses link it with those primitive races whose records are inscribed in our coal-seams. It 256 The Decticus: his Instrument is one of the first that mingled the sounds of hfe with the vague murmuring of inert things. It was singing before the reptile had learnt to breathe. This shows, from the mere point of view of sound, the futility of those theories of oiirs which try to explain the world by the automatic evolution of progress nascent in the primitive cell. All is yet dumb; and al- ready the insect is stridulating as correctly as it does to-day. Phonetics start with an apparatus which the ages will hand down to one another without changing any essential part of it. Then, though the lungs have ap- peared, we have silence, save for the heavy breathing of the nostrils. But lo, one day, the Frog croaks; and soon, with no prepara- tion, there are mingled with this hideous concert the trills of the Quail, the whistled stanzas of the Thrush and the Warbler's musical strains. The larynx in its highest form has come into existence. What will the late-comers do with it? The Ass and the Wild Boar give us our reply. We find something worse than marking time, we find an enormous retrogression, until one last bound brings us to man's own larynx. In this genesis of sounds it is impossible to 257 The Life of the Grasshopper talk authoritatively of a steady progression which makes the middling follow on the bad and the excellent on the middling. We see nothing but abrupt excursions, Intermittences, recoils, sudden expansions not foretold by what has gone before nor continued by that which follows; we find nothing but a riddle whose solution does not He In the virtues of the cell alone, that easy pillow for whoso has not the courage to search deeper. But let us leave the question of origins, that Inaccessible domain, and come down to facts; let us cross-examine a few representa- tives of those old races who were the earliest exponents of the art of sounds and took it into their heads to sing at a time when the mud of the first continents was hardening; let us ask them how their instrument is con- structed and what Is the object of their ditty. The Grasshopper, so remarkable both for the length and thickness of her hinder thighs and for her ovipositor, the sabre or dibble which plants her eggs, is one of the chief performers in the entomological concert. In- deed, If we except the Cicada, who Is often confused with her, she is responsible for the greater part of the noise. Only one of the Orthoptera surpasses her; and that is 258 The Decticus: his Instrument the Cricket, her near neighbour. Let us first hsten to the White-faced Decticus. The performance begins with a hard, sharp, almost metallic sound, very like that emitted by the Thrush keeping a sharp look- out while he stuffs himself with olives. It consists of a series of isolated notes, tick- tick, with a longish pause between them. Then, with a gradual crescendo, the song develops into a rapid clicking in which the fundamental tick-tick is accompanied by a continuous droning bass. At the end the cre- scendo becomes so loud that the metallic note disappears and the sound Is transformed into a mere rustle, a frrrr-frrrr-frrrr of the greatest rapidity. The performer goes on like this for hours, with alternating strophes and rests. In calm weather, the song, at its height, can be heard twenty steps away. That is no great di- stance. The noise made by the Cicada and the Cricket carries much farther. How are the strains produced? The books which I am able to consult leave me perplexed. They tell me of the " mirror," a thin, quivering membrane which glistens like a blade of mica; but how is this mem- brane made to vibrate? That Is what they 259 The Life of the Grasshopper either do not tell us or else tell us very vaguely and inaccurately, talking of a friction of the wing-cases, mutual rubbing of the nervures; and that Is all. I should like a more lucid explanation, for a Grasshopper's musical-box, I feel certain in advance, must have an exact mechanism of its own. Let us therefore look into the matter, even though we have to repeat ob- servations already perhaps made by others, but unknown to a recluse like myself, whose whole library consists of a few old odd volumes. The Decticus' wing-cases widen at the base and form on the Insect's back a flat sunken surface shaped like an elongated triangle. This is the sounding-board. Here the left wing-case folds over the right and, when at rest, completely covers the latter's musical apparatus. The most distinct and, from time immemorial, the best-known part of it is the mirror, thus called because of the shininess of Its thin oval membrane, set in the frame of a nervure. It is very like the skin of a drum, of an exquisitely delicate tympanum, with this difference, that it sounds without being tapped. Nothing touches the mirror when the Decticus sings. Its vibra- 260 The Decticus: his Instrument tions are imparted to it after starting else- where. And how? I will tell you. Its edging is prolonged at the inner angle of the base by a wide, blunt tooth, furnished at the end with a more prominent and power- ful fold than the other nervures distributed here and there. I will call this fold the friction-nervure. This is the starting-point of the concussion that makes the mirror re- sound. The evidence will appear when the remainder of the apparatus is known. This remainder, the motor mechanism, is on the left wing-case, covering the other with its flat edge. Outside, there is nothing re- markable, unless it be — and even then one has to be on the look-out for it — a sort of slightly slanting, transversal pad, which might very easily be taken for a thicker nervure than the others. But examine the lower surface through the magnifying-glass. The pad is much more than an ordinary nervure. It is an instru- ment of the highest precision, a magnificent indented bow, marvellously regular on its diminutive scale. Never did human industry, when cutting metal for the most delicate clockwork mechanism, achieve such perfec- tion. Its shape is that of a curved spindle. 261 The Life of the Grasshopper From one end to the other there have been cut across this bow about eighty triangular teeth, which are very even and are of some hard, durable material, dark-brown in colour. The use of this mechanical gem is obvious. If we take a dead Decticus and lift the flat rim of the two wing-cases slightly in order to place them In the position which they oc- cupy when sounding, we see the bow fitting its Indentations to the terminal nervure which I have called the friction-nervure ; we follow the line of teeth which, from end to end of the row, never swerve from the points to be set in motion; and, If the opera- tion be done at all dexterously, the dead insect sings, that Is to say, strikes a few of Its clicking notes. The secret of the sounds produced by the Decticus Is out. The toothed bow of the left wing-case Is the motor; the friction-nervure of the right wing-case Is the point of con- cussion; the stretched membrane of the mirror Is the resonator, to which vibration is communicated by the shaking of the sur- rounding frame. Our own music has many vibrating membranes; but these are always affected by direct percussion. Bolder than 262 The Decticus: his Instrument our makers of musical instruments, the Dec- ticus combines the bow with the drum. The same combination is found in the other Grasshoppers. The most famous of these is the Green Grasshopper {Locusta viridissima, LiN.), who to the quahties of a handsome stature and a fine green colour adds the honour of classical renown. In La Fontaine she is the Cicada who comes alms- begging of the Ant when the north wind blows. Flies and Grubs being scarce, the would-be borrower asks for a few grains to live upon until next summer. The double diet, animal and vegetable, is a very happy inspiration on the fabulist*s part. The Grasshopper, in fact, has the same tastes as the Decticus. In my cages, he feeds on lettuce-leaves when there is nothing better going; but his preference is all in favour of the Locust, whom he crunches ud without leaving anything but the wing-cases and wings. In a state of liberty, his preying on that ravenous browser must largely make up to us for the small toll which he levies on our agricultural produce. Except in a few details, his musical in- strument is the same as that of the Decticus. It occupies, at the base of the wing-cases, a 263 The Life of the Grasshopper large sunken surface shaped like a curved triangle and brownish in colour, with a dull- yellow rim. It Is a sort of escutcheon, em- blazoned with heraldic devices. On the under surface of the left wing-case, which Is folded over the right, two transversal, parallel grooves are cut. The space between them makes a ridge which constitutes the bow. The latter, a brown spindle, has a set of fine, very regular and very numerous teeth. The mirror of the right wing-case is almost circular, well framed and supplied with a strong and prominent friction-nervure. The insect stridulates in July and August, in the evening twilight, until close upon ten o'clock. It produces a quick, rattling noise, accompanied by a faint metallic clicklns^ which barely passes the border of perceptible sounds. The abdomen, considerably low- ered, throbs and beats the measure. This goes on for irregular periods and suddenly ceases; In between these periods there are false starts reduced to a few strokes of the bow; there are pauses and then the stridula- tion is once more In full swing. All said, it is a very meagre performance, greatly inferior in volume to that of the Dec- ticus, not to be compared with the song of 264 The Decticus: his Instrument the Cricket and even less with the harsh and noisy efforts of the Cicada. In the quiet of the evening, when only a few steps away, I need Httle Paul's delicate ear to apprise me of it. It is poorer still in the two dwarf Dectici of my neighbourhood, Platycleis intermedia^ Serv., and P. grisea, Fab., both of whom are common in the long grass, where the ground is stony and exposed to the sun, and quick to disappear in the undergrowth when you try to catch them. These two fat songsters have each had the doubtful privilege of a place in my cages. Here, in a blazing sun beating straight upon the window, are my little Dectici crammed with green millet-seeds and also with game. Most of them are lying in the hottest places, on their bellies or sides, with their hind-legs outstretched. For hours on end they digest without moving and slumber in their voluptuous attitude. Some of them sing. Oh, what a feeble song! The ditty of the Intermediary Decticus, with its strophes and pauses alternating at equal intervals, is a rapid fr-i'-r-r similar to the Coaltit's, while that of the Grey Decticus consists of distinct strokes of the bow and 265 The Life of the Grasshopper tends to copy the Cricket's melody, with a note which Is hoarser and, In particular, much fainter. In both cases, the feebleness of the sound hardly allows me to hear the singer a couple of yards away. And to produce this music, this insig- nificant and only just perceptible refrain, the two dwarfs have all that their big cousin possesses : a toothed bow, a tambourine, a frictlon-nervure. On the bow of the Grey Dectlcus I count about forty teeth and eighty on that of the Intermediary Dectlcus. Moreover, In both, the right wing-case dis- plays, around the mirror, a few diaphanous spaces, Intended no doubt to Increase the extent of the vibrating portion. It makes no difference : though the Instrument Is mag- nificent, the production of sound is very poor. With this same mechanism of a drum and file, which of them will achieve any progress? Not one of the large-winged Locustidse suc- ceeds In doing so. All, from the biggest, the Grasshoppers, DecticI and ConoccDhall, down to the smallest, the Platycleis, Xlphl- dlon and Phaneropteron, set In motion with the teeth of a bov/ the frame of a vlbratlng- mirror; all are, so to speak, left-handed, that IS to say, they carry the bow on the lower 266 The Decticus: his Instrument surface of the left wing-case, overlapping the right, which is furnished with the tympanum; all, lastly, have a thin, faint trill which is sometimes hardly perceptible. One alcne, modifying the details of the apparatus without introducing any innovation into the general structure, achieves a certain power of sound. This is the Vine Ephip- piger, who does without wings and reduces his wing-cases to two concave scales, ele- gantly fluted and fitting one into the other. These two disks are all that remains of the organs of flight, which have become ex- clusively organs of song. The insect aban- dons flying to devote itself the better to stridulation. It shelters its instrument under a sort of dome formed by the corselet, which is curved saddlewise. As usual, the left scale occupies the upper position and bears on its lower surface a file in which we can distinguish with the lens eighty transversal denticulations, more powerful and more clearly cut than those possessed by any other of the Grass- hopper tribe. The right scale is underneath. At the top of its slightly flattened dome, the mirror gleams, framed in a strong nervure. For elegance of structure, this instrument 267 The Life of the Grasshopper Is superior to the Cicada's, In which the con- traction of two columns of muscles alternately pulls In and lets out the convex surface of two barren cymbals. It needs sound- chambers, resonators, to become a noisy ap- paratus. As things are, It emits a lingering and plaintive tchi-i-i, tchi-i-i, tchi-i-i, In a minor key, which is heard even farther than the blithe bowing of the White-faced Dectlcus. When disturbed in their repose, the Dec- tlcus and the other Grasshoppers at once become silent, struck dumb with fear. With them, singing invariably expresses gladness. The Ephlppiger also dreads to be disturbed and baffles with his sudden silence whoso seeks to find him. But take him between your fingers. Often he will resume his strldulation with erratic strokes of the bow. At such times the song denotes anything but happiness, fear rather and all the anguish of danger. The Cicada likewise rattles more shrilly than ever when a ruthless child dis- locates his abdomen and forces open his chapels. In both cases, the gay refrain of the mirthful Insect turns Into the lamentation of a persecuted victim. A second peculiarity of the Ephlppiger*s, 268 The Decticus: his Instrument unknown to the other singing insects, is worthy of remark. Both sexes are endowed with the sound-producing apparatus. The female, who, in the other Grasshoppers, is always dumb, with not even a vestige of bow or mirror, acquires in this instance a musical instrument which is a close copy of the male's. The left scale covers the right. Its edges are fluted with thick, pale nervures, forming a fine-meshed network; the centre, on the other hand, is smooth and swells into an amber-coloured dome. Underneath, this dome is supplied with two concurrent ner- vures, the chief of which is slightly wrinkled on Its ridge. The right scale is similarly constructed, but for one detail : the central dome, which also is amber-coloured, is traversed by a nervure which describes a sort of sinuous line and which, under the mag- nifying-glass, reveals very fine transversal teeth throughout the greater part of its length. This feature betrays the bow, placed In the Inverse position to that which Is known to us. The male Is left-handed and works with his upper wing-case ; the female Is right- handed and scrapes with her lower wlng- 269 The Life of the Grasshopper case. Besides, with her, there is no such thing as a mirror, that is to say, no shiny- membrane resembhng a flake of mica. The bow rubs across the rough vein of the oppo- site scale and in this way produces simul- taneous vibration in the two fitted spherical domes. The vibrating part is double, therefore, but too stiff and clumsy to produce a sound of any depth. The song, in any case rather thin, is even more plaintive than the male's. The insect is not lavish with it. If I do not Interfere, my captives never add their note to the concert of their caged companions; on the other hand, when seized and worried, they utter a moan at once. It seems likely that, in a state of liberty, things happen otherwise. The dumb beauties In my bell- jars are not for nothing endowed with a double cymbal and a bow. The Instrument that moans with fright must also ring out joyously on occasion. What purpose is served by the Grasshop- per's sound-apparatus? I will not go so far as to refuse It a part in the pairing, or to deny it a persuasive murmur, sweet to her who hears it: that would be flying In the face of the evidence. But this is not Its prin- 270 The Decticus: his Instrument cipal function. Before anything else, the insect uses it to express its joy in hving, to sing the dehghts of existence with a belly well filled and a back warmed by the sun, as witness the big Decticus and the male Grasshopper, who, after the wedding, ex- hausted for good and all and taking no fur- ther interest in pairing, continue to stridu- late merrily as long as their strength holds out. The Grasshopper tribe has its bursts of gladness; it has moreover the advantage of being able to express them with a sound, the simple satisfaction of the artist. The little journeyman whom I see in the evening re- turning from the workyard on his way home, where his supper awaits him, whistles and sings for his pwn pleasure, with no intention of making himself heard, nor any wish to attract an audience. In his artless and almost unconscious fashion, he tells the joys of a hard day's work done and of his plate- ful of steaming cabbage. Even so most often does the singing insect stridulate : it is celebrating life. Some go farther. If existence has its sweets, it also has its sorrows. The saddle- bearing Grasshopper of the vines is able to 271 The Life of the Grasshopper translate both of these into sound. In a trailing melody, he sings to the bushes of his happiness; in a like melody, hardly altered, he pours forth his griefs and his fears. His mate, herself an instrumentalist, shares this privilege. She exults and laments with two cymbals of another pattern. When all is said, the cogged drum need not be looked down upon. It enlivens the lawns, murmurs the joys and tribulations of existence, sends the lover's call echoing all around, brightens the weary waiting of the lonely ones, tells of the perfect blossoming of insect life. Its stroke of the bow is almost a voice. And this magnificent gift, so full of promise, is granted only to the inferior races, coarse natures, near akin to the crude begin- nings of the carboniferous period. If, as we are told, the superior insect descends from ancestors who have been gradually trans- formed, why did it not preserve that fine in- heritance of a voice which has sounded from the earliest ages? Can it be that the theory of progressive acquirements is only a specious lure? Are we to abandon the savage theory of the crushing of the weak by the strong, of the 272 The Decticus: his Instrument less well-endowed by their more highly-gifted rivals? Is it permissible to doubt, when the evolutionists talk to us of the survival of the fittest? Yes, indeed it is! We are told as much by a certain Libellu- la of the carboniferous age {Meganeura Monyi, Brong. ), measuring over two feet across the wings. The giant Dragon-fly, who terrified the small winged folk with her sawlike mandibles, has disappeared, whereas the puny Agrion, with her bronze or azure abdomen, still hovers over the reeds of our rivers. So have her contemporaries disappeared, the monstrous sauroid fishes, mailed in enamel and armed to the teeth. Their scarce successors are mere abortions. The splendid series of Cephalopods with parti- tioned shells, including certain Ammonites of the diameter of a cartwheel, has no other representative in our present seas than that modest fireman's helmet, the Nautilus. The Megalosaurus, a saurian twenty-five yards long, was a more alarming figure in our country-sides than the Grey Lizard of the walls. One of man's contemporaries, that monumental beast the Mammoth, is known only by his remains; and his near kinsman 27Z The Life of the Grasshopper the Elephant, a mere Sheep beside him, goes on prospering. What a shock to the law of the survival of the strongest! The mighty have gone under; and the weak fill their place. 274 CHAPTER XIV THE GREEN GRASSHOPPER. \T7'E are in the middle of July. The ^^ astronomical dog-days are just begin- ning; but in reality the torrid season has anticipated the calendar and for some weeks past the heat has been overpowering. This evening in the village they are cele- brating the National Festival.^ While the little boys and girls are hopping around a bonfire whose gleams are reflected upon the church-steeple, while the drum is pounded to mark the ascent of each rocket, I am sit- ting alone in a dark corner, In the compara- tive coolness that prevails at nine o'clock, harking to the concert of the festival of the fields, the festival of the harvest, grander by far than that which, at this moment, is being celebrated in the village square with gun- powder, lighted torches, Chinese lanterns * The 14th of July, the anniversary of the fall of the Bastille. — Translator's Note. 275 The Life of the Grasshopper and, above all, strong drink. It has the sim- plicity of beauty and the repose of strength. It is late; and the Cicadas are silent. Glutted with light and heat, they have in- dulged in symphonies all the livelong day. The advent of the night means rest for them, but a rest frequently disturbed. In the dense branches of the plane-trees, a sudden sound rings out like a cry of anguish, strident and short. It is the desperate wail of the Cicada, surprised in his quietude by the Green Grass- hopper, that ardent nocturnal huntress, who springs upon him, grips him in the side, opens and ransacks his abdomen. An orgy of music, followed by butchery. I have never seen and never shall see that supreme expression of our national revelry, the military reviev/ at Longchamp; nor do I much regret it. The newspapers tell me as much about it as I want to know. They give me a sketch of the site. I see, installed here and there amid the trees, the ominous Red Cross, with the legend, " Mili- tary Ambulance; Civil Ambulance." There will be bones broken, apparently; cases of sunstroke; regrettable deaths, perhaps. It is all provided for and all in the programme. Even here, in my village, usually so peace- 276 The Green Grasshopper able, the festival will not end, I am ready to wager, without the exchange of a few blows, that compulsory seasoning of a day of merry- making. No pleasure, it appears, can be fully relished without an added condiment of pain. Let us listen and meditate far from the tumult. While the disembowelled Cicada utters his protest, the festival up there In the plane-trees is continued with a change of orchestra. It Is now the time of the noc- turnal performers. Hard by the place of slaughter. In the green bushes, a delicate ear perceives the hum of the Grasshoppers. It Is the sort of noise that a spinning-wheel makes, a very unobtrusive sound, a vague rustle of dry membranes rubbed together. Above this dull bass there rises, at Intervals, a hurried, very shrill, almost metallic click- ing. There you have the air and the recita- tive, Intersected by pauses. The rest Is the accompaniment. Despite the assistance of a bass. It is a poor concert, very poor indeed, though there are about ten executants In my Immediate vicinity. The tone lacks Intensity. My old tympanum Is not always capable of perceiv- ing these subtleties of sound. The little that 277 The Life of the Grasshopper reaches me is extremely sweet and most ap- propriate to the calm of twilight. Just a little more breadth in your bow-stroke, my dear Green Grasshopper, and your technique would be better than the hoarse Cicada's, whose name and reputation you have been made to usurp in the countries of the north. Still, you will never equal your neighbour, the little bell-ringing Toad, who goes tinkling all round, at the foot of the plane-trees, while you click up above. He is the smallest of my batrachian folk and the most venture- some in his expeditions. How often, at nightfall, by the last glim- mers of daylight, have I not come upon him as I wandered through my garden, hunting for Ideas ! Something runs away, rolling over and over in front of me. Is it a dead leaf blown along by the wind? No, it is the pretty little Toad disturbed In the midst of his pilgrimage. He hurriedly takes shelter under a stone, a clod of earth, a tuft of grass, recovers from his excitement and loses no time In picking up his liquid note. On this evening of national rejoicing, there are nearly a dozen of him tinkling against one another around me. Most of them are crouching among the rows of 278 The Green Grasshopper flower-pots that form a sort of lobby outside my house. Each has his own note, always the same, lower in one case, higher in an- other, a short, clear note, melodious and of exquisite purity. With their slow, rhythmical cadence, they seem to be intoning litanies. Cluck, says one ; dick, responds another, on a finer note ; clock, adds a third, the tenor of the band. And this is repeated indefinitely, like the bells of the village pealing on a holiday: cluck, click, clock; cluck, click, clock! The batrachian choristers remind me of a certain harmonica which I used to covet when my six-year-old ear began to awaken to the magic of sounds. It consisted of a series of strips of glass of unequal length, hung on two stretched tapes. A cork fixed to a wire served as a hammer. Imagine an unskilled hand striking at random on this key-board, with a sudden clash of octaves, dissonances and topsy-turvy chords; and you will have a pretty clear idea of the Toads' litany. As a song, this litany has neither head nor tail to it; as a collection of pure sounds, it is delicious. This is the case with all the music in nature's concerts. Our ear dis- 279 The Life of the Grasshopper covers superb notes in it and then becomes refined and acquires, outside the reahties of sound, that sense of order which is the first condition of beauty. Now this sweet ringing of bells between hiding-place and hiding-place is the matri- monial oratorio, the discreet summons which j every Jack issues to his Jill. The sequel to the concert may be guessed without further enquiry; but what it would be impossible to foresee is the strange finale of the wedding. Behold the father, in this case a real pater- familias, in the noblest sense of the word, coming out of his retreat one day in an un- recognizable state. He is carrying the future, tight-packed around his hind-legs; he is changing houses laden with a cluster of eggs the size of pepper-corns. His calves are girt, his thighs are sheathed with the bulky burden; and it covers his back like a beggar's wallet, completely deforming him. Whither is he going, dragging himself, along, incapable of jumping, thanks to the weight of his load? He is going, the fond parent, where the mother refuses to go; he is on his way to the nearest pond, whose warm waters are indispensable to the tad- poles' hatching and existence. When the 280 The Green Grasshopper eggs are nicely ripened around his legs under the humid shelter of a stone, he braves the damp and the daylight, he the passionate lover of dry land and darkness; he advances by short stages, his lungs congested v^^ith fatigue. The pond is far away, perhaps; no matter: the plucky pilgrim will find it. He's there. Without delay, he dives, despite his profound antipathy to bathing; and the cluster of eggs is instantly removed by the legs rubbing against each other. The eggs are now in their element; and the rest will be accomplished of itself. Having ful- filled his obligation to go right under, the father hastens to return to his well-sheltered home. He is scarcely out of sight before the little black tadpoles are hatched and playing about. They were but waiting for the contact of the water in order to burst their shells. Among the singers in the July gloaming, one alone, were he able to vary his notes, could vie with the Toad's harmonious bells. This is the little Scops-owl, that comely noc- turnal bird of prey, with the round gold eyes. He sports on his forehead two small feathered horns which have won for him in the district the name of Machoto banarudo, 281 The Life of the Grasshopper the Horned Owl. His song, which is rich enough to fill by itself the still night air, is of a nerve-shattering monotony. With im- perturbable and measured regularity, for hours on end, kew^ kew, the bird spits out its cantata to the moon. One of them has arrived at this moment, driven from the plane-trees in the square by the din of the rejoicings, to demand my hos- pitality. I can hear him in the top of a cypress near by. From up there, dominating the lyrical assembly, at regular intervals he cuts into the- vague orchestration of the Grasshoppers and the Toads. His soft note is contrasted, intermittently, with a sort of Cat's mew, coming from an- other spot. This is the call of the Common Owl, the meditative bird of Minerva. After hiding all day in the seclusion of a hollow olive-tree, he started on his wanderings Avhen the shades of evening began to fall. Swing- ing along with a sinuous flight, he came from somewhere in the neighbourhood to the pines in my enclosure, whence he mingles his harsh mewing, slightly softened by distance, with the general concert. The Green Grasshopper's clicking is too faint to be clearly perceived amidst these 282 The Green Grasshopper clamourers; all that reaches me is the least ripple, just noticeable when there is a mo- ment's silence. He possesses as his ap- paratus of sound only a modest drum and scraper, whereas they, more highly privi- leged, have their bellows, the lungs, which send forth a column of vibrating air. There is no comparison possible. Let us return to the insects. One of these, though inferior In size and no less sparingly equipped, greatly surpasses the Grasshopper in nocturnal rhapsodies. I speak of the pale and slender Italian Cricket {CEcanthus pellucens, Scop.), who is so puny that you dare not take him up for fear of crushing him. He makes music everywhere among the rosemary-bushes, while the Glow-worms light up their blue lamps to complete the revels. The delicate instrumentalist consists chiefly of a pair of large wings, thin and gleaming as strips of mica. Thanks to these dry sails, he fiddles away with an intensity capable of drowning the Toads' fugue. His performance sug- gests, but with more brilliancy, more tremolo in the execution, the song of the Common Black Cricket. Indeed the mistake would certainly be made by any one who did not 283 The Life of the Grasshopper know that, by the time that the very hot weather comes, the true Cricket, the chorister of spring, has disappeared. His pleasant violin has been succeeded by another more pleasant still and worthy of special study. We shall return to him at an opportune moment. These then, limiting ourselves to select specimens, are the principal participants in this musical evening: the Scops-owl, with his languorous solos; the Toad, that tinkler of sonatas; the Italian Cricket, who scrapes the first string of a violin; and the Green Grass- hopper, who seems to beat a tiny steel triangle. We are celebrating to-day, with greater uproar than conviction, the new era, dating politically from the fall of the Bastille; they, with glorious Indifference to human things, are celebrating the festival of the sun, singing the happiness of existence, sounding the loud hosanna of the July heats. What care they for man and his fickle rejoicings ! For whom or for what will our squibs be spluttering a few years hence? Far-seeing indeed would he be who could answer the question. Fashions change and bring us the unexpected. The time-serving 284 The Green Grasshopper rocket spreads its sheaf of sparks for the public eneray of yesterday, who has become the idol of to-day. To-morrow it will go up for somebody else. In a century or two, will any one, outside the historians, give a thought to the taking of the Bastille? It is very doubtful. We shall have other joys and also other cares. Let us look a little farther ahead. A day will come, so everything seems to tell us, when, after making progress upon progress, man will succumb, destroyed by the excess of what he calls civilization. Too eager to play the god, he cannot hope for the animal's placid longevity; he will have disappeared when the little Toad is still saying his litany, in company with the Grasshopper, the Scops- owl and the others. They were singing on this planet before us; they will sing after us, celebrating what can never change, the fiery glory of the sun. I will dwell no longer on this festival and will become once more the naturalist, anxious to obtain information concerning the private life of the insect. The Green Grasshopper (Locusta viridissinia, LiN.) does not appear to be common in my neighbourhood. Last year, Intending to make a study of this in- 285 The Life of the Grasshopper sect and finding my efforts to hunt It fruit- less, I was obliged to have recourse to the good offices of a forest-ranger, who sent me a pair of couples from the Lagarde plateau, that bleak district where the beech-tree be- gins its escalade of the Ventoux. Now and then freakish fortune takes It Into her head to smile upon the persevering. What was not to be found last year has be- come almost common this summer. Without leaving my narrow enclosure, I obtain as many Grasshoppers as I could wish. I hear them rustling at night In the green thickets. Let us make the most of the windfall, which perhaps will not occur again. In the month of June, my treasures are Installed, In a sufficient number of couples, under a wire cover standing on a bed of sand in an earthen pan. It is Indeed a mag- nificent Insect, pale-green all over, with two whitish stripes running down its sides. Its imposing size. Its slim proportions and Its great gauze wings make It the most elegant of our Locustldas. I am enraptured with my captives. What will they teach me? We shall see. For the moment, we must feed them. I have here the same difficulty that I had 286 The Green Grasshopper with the Dectlcus. Influenced by the general diet of the Orthoptera/ those ruminants of the greenswards, I offer the prisoners a leaf of lettuce. They bite into it, certainly, but very sparingly and with a scornful tooth. It soon becomes plain that I am dealing with half-hearted vegetarians. They want some- thing else : they are beasts of prey, appar- ently. But what manner of prey? A lucky chance taught me. At break of day I was pacing up and down outside my door, when something fell from the nearest plane-tree with a shrill grating sound. I ran up and saw a Grasshopper gutting the belly of an exhausted Cicada. In vain the victim buzzed and waved his limbs : the other did not let go, dipping her head right into the entrails and rooting them out by small mouthfuls. I knew what I wanted to know : the attack had taken place up above, early In the morn- ing, while the Cicada was asleep; and the plunging of the poor wretch, dissected alive, had made assailant and assailed fall In a * The order of insects comprising the Grasshoppers, Locusts, Crickets, Cockroaches, Mantes and Earwigs. The Cicada, with whom the present volume opens, and the Foamy Cicadella, with whom it closes, belong to the order of Homoptera. — Translator's Note. 2^7 The Life of the Grasshopper bundle to the ground. Since then I have repeatedly had occasion to witness similar carnage. I have even seen the Grasshopper — the height of audacity, this — dart in pursuit of a Cicada in mad flight. Even so does the Sparrow-hawk pursue the Swallow^ in the sky. But the bird of prey here is inferior to the insect. It attacks a weaker than Itself. The Grasshopper, on the other hand, assaults a colossus, much larger than herself and stronger; and nevertheless the result of the unequal fight is not in doubt. The Grasshopper rarely fails with the sharp pliers of her powerful jaws to disembowel her capture, which, being unprovided with weapons, confines Itself to crying out and kicking. The main thing is to retain one's hold of the prize, which is not difl^cult In somnolent darkness. Any Cicada encountered by the fierce Locustid on her nocturnal rounds Is bound to die a lamentable death. This ex- plains those sudden agonized notes which grate through the w^oods at late, unseason- able hours, when the cymbals have long been silent. The murderess In her suit of apple- green has pounced on some sleeping Cicada. 288 The Green Grasshopper My boarders' menu Is settled : I will feed them on Cicadas. They take such a Uking to this fare that, in two or three weeks, the floor of the cage is a knacker's yard strewn with heads and empty thoraces, with torn-off wings and disjointed legs. The belly alone disappears almost entirely. This is the tit- bit, not very substantial, but extremely tasty, it would seem. Here, in fact, in the insect's crop, the syrup is accumulated, the sugary sap which the Cicada's gimlet taps from the tender bark. Is It because of this dainty that the prey's abdomen Is preferred to any other morsel? It Is quite possible. I do, in fact, with a view to varying the diet, decide to serve up some very sweet fruits, slices of pear, grape-pips, bits of melon. All this meets with dehghted appre- ciation. The Green Grasshopper resembles the English : she dotes on underdone rump- steak seasoned with jam.^ This perhaps is * The author was obviously thinking of the English- man's saddle of mutton and red-currant jelly. The mis- take has been repeated much nearer to these shores. I have in mind the true story of an Irish king's counsel singing the praises of another, still among us, who had married an English wife and who, in the course of an extensive practice in the House of Lords, spent much of his time in England: "Ah, is a real gentleman! He speaks with 289 The Life of the Grasshopper why, on catching the Cicada, she first rips up his paunch, which supplies a mixture of flesh and preserves. To eat CicadsE and sugar is not possible in every part of the country. In the north, where she abounds, the Green Grasshopper would not find the dish which attracts her so strongly here. She must have other re- sources. To convince myself of this, I give her Anoxias {A. pilosa, Fab.), the summer equivalent of the spring Cockchafer. The Beetle is accepted without hesitation. No- thing is left of him but the wing-cases, head and legs. The result is the same with the magnificent plump Pine Cockchafer (Melo- lontha fullo, LiN.), a sumptuous morsel which I find next day eviscerated by my gang of knackers. These examples teach us enough. They tell us that the Grasshopper is an inveterate consumer of insects, especially of those which are not protected by too hard a cuirass; they are evidence of tastes which an EngiHsh accent, quotes Euripides in the original Latin and takes jam with his meat." I venture to thinic that Fabre, in the gentleness of his heart, would have forgiven his translator for quoting this flippant anecdote. I have no other excuse. — Trans- lator's Note. 290 The Green Grasshopper are highly carnivorous, but not exclusively so, like those of the Praying Mantis, who refuses everything except game. The butcher of the Cicadas is able to modify an excessively heating diet with vegetable fare. After meat and blood, sugary fruit-pulp; sometimes even, for lack of anything better, a little green stuff. Nevertheless, cannibalism is prevalent. True, I never witness in my Grasshopper- cages the savagery which is so common in the Praying Mantis, who harpoons her rivals and devours her lovers; but, if some weakling succumb, the survivors hardly ever fail to profit by his carcass as they would in the case of any ordinary prey. With no scarcity of provisions as an excuse, they feast upon their defunct companion. For the rest, all the sabre-bearing clan display, in varying degrees, a propensity for filling their bellies with their maimed comrades. In other respects, the Grasshoppers live together very peacefully in my cages. No serious strife ever takes place among them, nothing beyond a little rivalry in the matter of food. I hand in a piece of pear. A Grasshopper alights on it at once. Jealously she kicks away any one trying to bite at the 291 The Life of the Grasshopper delicious morsel. Selfishness reigns every- where. When she has eaten her fill, she makes way for another, who in her turn becomes intolerant. One after the other, all the inmates of the menagerie come and re- fresh themselves. After cramming their crops, they scratch the soles of their feet a little with their mandibles, polish up their forehead and eyes with a leg moistened with spittle and then, hanging to the trelllswork or lying on the sand in a posture of con- templation, blissfully they digest and slum- ber most of the day, especially during the hottest part of It. It is In the evening, after sunset, that the troop becomes lively. By nine o'clock the animation is at Its height. With sudden rushes they clamber to the top of the dome, to descend as hurriedly and climb up once more. They come and go tumultuously, run and hop around the circular track and, with- out stopping, nibble at the good things on the way. The males are strldulating by themselves, here and there, teasing the passing fair with their antenns. The future mothers stroll about gravely, with their sabre half-raised. The agitation and feverish excitement means 292 The Green Grasshopper that the great business of pairing Is at hand. The fact will escape no practised eye. It is also what I particularly wish to ob- serve. My chief object In stocking my cages was to discover how far the strange nuptial manners revealed by the White-faced Dec- tlcus might be regarded as general. My wish is satisfied, but not fully, for the late hours at which events take place did not allow me to witness the final act of the wedding. It is late at night or early in the morning that things happen. The little that I see is confined to interminable preludes. Standing face to face, with foreheads almost touching, the lovers feel and sound each other for a long time with their limp antennae. They suggest two fencers crossing and recrossing harmless foils. From time to time, the male stridu- lates a little, gives a few short strokes of the bow and then falls silent, feeling perhaps too much overcome to continue. Eleven o'clock strikes; and the declaration is not yet over. Very regretfully, but conquered by sleepiness, I quit the couple. Next morning, early, the female carries, hanging at the bottom of her ovipositor, the queer bladderlike arrangement that surprised 293 The Life of the Grasshopper us so much in the Decticus. It is an opaline capsule, the size of a large pea and roughly subdivided into a small number of egg- shaped vesicles. When the Grasshopper walks, the thing scrapes along the ground and becomes dirty with sticky grains of sand. The final banquet of the female Decticus is seen again here in all its hideousness. When, after a couple of hours, the fertihzing capsule is drained of its contents, the Grass- hopper devours it bit by bit; for a long time she chews and rechews the gummy morsel and ends by swallowing it all down. In less than half a day, the milky burden has dis- appeared, consumed with zest down to the last atom. The inconceivable therefore, imported, one would think, from another planet, so far removed is it from earthly habits, reap- pears with no noticeable variation in the Grasshopper, following on the Decticus. What singular folk are the Locustidas, one of the oldest races in the animal kingdom on dry land! It seems probable that these eccentricities are the rule throughout the order. Let us consult another sabre-bearer. I select the Ephippiger {Ephippigera vitiiim, Serv.), who is so easy to rear on 294 The Green Grasshopper bits of pear and lettuce-leaves. It is in July and August that things happen. A little way off, the male is stridulating by himself. His ardent bow-strokes set his whole body quivering. Then he stops. Little by little, with slow and almost ceremonious steps, the caller and the called come closer together. They stand face to face, both silent, both stationary, their antennae gently swaying, their fore-legs raised awkwardly and giving a sort of handshake at intervals. The peaceful interview lasts for hours. What do they say to each other? What vows do they exchange? What does their ogling mean? But the moment has not yet come. They separate, they fall out and each goes his own way. The coolness does not last long. Here they are together again. The tender declara- tions are resumed, with no more success than before. At last, on the third day, I behold the end of the preliminaries. The male slips discreetly under his companion, backwards, according to the immemorial laws and cus- toms of the Crickets. Stretched out behind and lying on his back, he clings to the ovi- positor, his prop. The pairing is accom- plished. 295 The Life of the Grasshopper The result is an enormous spermatophore, a sort of opalescent raspberry with large seeds. Its colour and shape remind one of a cluster of SnalTs-eggs. I remember seeing the same effect once with a Decticus, but in a less striking form; and I find it again in the Green Grasshopper's spermatophore. A thin median groove divides the whole into two symmetrical bunches, each comprising seven or eight spherules. The two nodes situated right and left of the bottom of the ovipositor are more transparent than the others and contain a bright orange-red kernel. The whole thing Is attached by a wide pedicle, a dab of sticky jelly. As soon as the thing Is placed in position, the shrunken male flees and goes to recruit, after his disastrous prowess, on a slice of pear. The other, not at all troubled In spite of her heavy load, wanders about on the trelllswork of the cage, taking very short steps as she slightly raises her raspberry, this enormous burden, equal In bulk to half the creature's abdomen. Two or three hours pass In this way. Then the Ephlpplger curves herself Into a ring and with her mandibles picks off part- icles of the nippled capsule, without burst- 296 The Green Grasshopper ing it, of course, or allowing the contents to flow forth. She strips its surface by remov- ing tiny shreds, which she chews in a lei- surely fashion and swallows. This fastidi- ous consuming by atoms is continued for a whole afternoon. Next day the raspberry has disappeared; the whole of it has been gulped down during the night. At other times the end is less quick and, above all, less repulsive. I have kept a note of an Ephippiger who was dragging her satchel along the ground and nibbling at it from time to time. The soil Is uneven and rugged, having been recently turned over with the blade of a knife. The raspberry- like capsule picks up grains of sand and little clods of earth, which increase the weight of the load considerably, though the insect ap- pears to pay no heed to it. Sometimes the carting becomes laborious, because the load sticks to some bit of earth that refuses to move. In spite of the efforts made to re- lease the thing, it does not become detached from the point where it hangs under the ovipositor, thus proving that it possesses no small power of adhesion. All through the evening, the Ephippiger roams about aimlessly, now on the wire- 297 The Life of the Grasshopper work, anon on the ground, wearing a preoc- cupied air. Oftener still she stands without moving. The capsule withers a little, but does not decrease notably in volume. There are no more of those mouthfuls which the Ephippiger snatched at the beginning; and the little that has already been removed affects only the surface. Next day, things are as they were. There is nothing new, nor on the morrow either, save that the capsule withers still more, though Its two red dots remain almost as bright as at first. Finally, after sticking on for forty-eight hours, the whole thing comes off without the insect's Intervention. The capsule has yielded its contents. It Is a dried-up wreck, shrivelled beyond recog- nition, left lying In the gutter and doomed sooner or later to become the booty of the Ants. Why Is It thus abandoned when. In other cases, I have seen the Ephippiger so greedy for the morsel? Perhaps because the nuptial dish had become too gritty with grains of sand, so unpleasant to the teeth. Another Locustid, the Phaneroptera who carries a short yataghan bent Into a reaping- hook (P. falcata, Scop.), has made up to me in part for my stud troubles. Repeatedly, 298 The Green Grasshopper but always under conditions which did not allow of completing my observation, I have caught her carrying the fertilizing-concern under the base of her sabre. It is a dia- phanous, oval phial, measuring three or four millimetres ^ and hanging from a crystal thread, a neck almost as long as the dis- tended part. The insect does not touch it, but leaves the phial to dry up and shrivel where it Is.^ Let us be content with this. These five examples, furnished by such different genera, Decticus, Analota, Grasshopper, Ephippiger and Phaneroptera, prove that the Locustid, like the Scolopendra and the Cephalopod, is a belated representative of the manners of antiquity, a valuable specimen of the genetic eccentricities of olden times. * .117 to .156 inch. — Translator's Note. ^ Fuller details on this curious subject would be out of place in a book in which anatomy and physiology cannot always speak quite freely. They will be found in my essay on the Locustidae which appeared in the Annates des sciences naturelles, 1896. — Author's Note. 299 CHAPTER XV THE CRICKET: THE BURROW; THE EGG ALMOST as famous as the Cicada, the *■ Field Cricket, the denizen of the greenswards, figures among the limited but glorious number of the classic insects. He owes this honour to his song and his house. One thing alone is lacking to complete his renown. By a regrettable omission, the master of the art of making animals talk gives him hardly two lines. In one of his fables he shows us the Hare seized with terror at the sight of his ears, which scandalmongers will not fail to de- scribe as horns at a time when to be horned Is dangerous. The prudent animal packs up his traps and makes off : *' Adieu, volsin Grillon/' dit-il; " je pars d'ici; '' Mes oreilles en fin seraient comes aussi** 300 The Cricket: the Burrow The Cricket answers : " Comes celaf Voiis me prenez pour criiche! ^' Ce sont oreilles que Dieu ft" The Hare Insists : '^ On les fera passer pour comes." ^ And that Is all. What a pity that La Fon- taine did not make the insect hold forth at greater length ! The good-natured Cricket is depicted for us In a couple of lines which already show the master's touch. No, indeed, he is no fool : his big head might have found some capital things to say. And yet the Hare was perhaps not wrong to take his departure in a hurry. When slander is at your heels, the best thing is to fly. * '* Fare thee well, good neighbour Cricket; from thy presence I must flee; " Mine ears also will be taken for a pair of horns," said he. " Horns, i' faith ! " the Cricket answered. " Is thy servant mad or blind? *' Those are ears which thy Creator with His own hand hath designed ! " " Yet the world will one day call them horns," his fellow made reply, " And ere that day dawn, my neighbour, I will bid this place good-bye." 301 The Life of the Grasshopper Florlan ^ was less concise in his story, which is on another theme; but what a long way we are from the warmth and vigour of old La Fontaine ! In Florian's fable Le Grillon, there are plenty of flowery mead- ows and blue skies; Dame Nature and af- fectation go hand in hand; in short, we have the feeble artificialities of a lifeless rhetoric, which loses sight of the thing described for the sake of the description. It lacks the sim- plicity of truth and also the saving salt of humour. Besides, what a preposterous idea, to represent the Cricket as discontented, be- wailing his condition in despair ! All who have studied him know, on the contrary, that he is very well pleased with his own talent and his hole. This, moreover, is what the fabulist makes him admit, after the Butter- fly's discomfiture : '^ Combien je vats aimer ma retraite pro- fond e I ^^ Pour zivre heiireiix, vivons cache /^^ ■ ^ Jean Pierre Claris de Florian (1755-1794), Voltaire's grand-nephew, the leading French fabulist, after La Fontaine. — Translator's Note. ^ " My snug little home is a place of delight: " If you want to live happy, live hidden from sight! " 302 The Cricket: the Burrow I find more force and more truth in the apologue by the nameless friend to whom I owe the Provencal piece, La Cigalo e la Foiirnigo. He will forgive me if for the second time I expose him, without his con- sent, to the dangerous honour of print. Here it is: Le Grillon L'histoire des betes rapporte Qu' autrefois un pauvre grillon, Pre nan t le soleil sur sa porte, Fit passer un beau papillon. Un papillon a longues queues, Superbe, des mieux decores, Avec rangs de lunules bleues, Galons noirs et gros points dores^ '' Vole, vole,^* lui dit Vermite, '' Sur les fleurs, du matin au soir; ** Ta rose, ni ta marguerite Ne valent mon humble manoir/* II disait vrai.

Mais la tourmente en rien n'etonne Le grillon, qui, dans son abri, Qu'il pleuve, qu'il vente, qu'il tonne, Vit tranquille et chante cri-cri. Ah! n^allons pas courir le monde Parmi les plaisirs et les fleurs; L'humble foyer, sa paix profonde Nous epargneront bien des pleurs, THE CRICKET Among the beasts a tale is told How a poor Cricket ventured nigh His door to catch the sun's warm gold And saw a radiant Butterfly. She passed with tails thrown proudl}^ back And long gay rows of crescents blue, Brave yellow stars and bands of black, The lordliest fly that ever flew. " Ah, fly away," the hermit said, ** Daylong among your flowers to roam ; " Nor daisies white nor roses red *' Will compensate my lowly home." True, all too true! There came a storm And caught the other in its flood, 304 The Cricket: the Burrow Staining her broken velvet form And covering her wings w^ith mud. The Cricket, sheltered from the rain, Chirped and looked on w^ith tranquil eye; For him the thunder pealed in vain, The gale and torrent passed him by. Then shun the w^orld, nor take your fill Of any of its joys or flowers; A lowly fire-side, calm and still, At least will grant you tearless hours! ^ There I recognize my Cricket. I see him curling his antennae on the threshold of his burrow, keeping his belly cool and his back to the sun. He is not jealous of the But- terfly; on the contrary, he pities her, with that air of mocking commiseration familiar in the ratepayer who owns a house of his own and sees passing before his door some wearer of a gaudy costume with no place to lay her head. Far from complaining, he is very well satisfied with both his house and his violin. A true philosopher, he knows the vanity of things and appreciates the charm of a modest retreat away from the riot of pleasure-seekers. ' For the translation of these and the other verses in this chapter I am indebted to my friend Mr. Stephen McKenna. — Translator's Note. 305 The Life of the Grasshopper Yes, the description is about right, though it remains very inadequate and does not bear the stamp of immortahty. The Cricket is still waiting for the few lines needed to perpetuate his merits; and, since La Fontaine neglected him, he will have to go on waiting a long time. To me, as a naturalist, the outstanding feature in the two fables — a feature which I should find repeated elsewhere, beyond a doubt, if my library were not reduced to a small row of odd volumes on a deal shelf — is the burrow on which the moral is founded. Florian speaks of the snug retreat; the other praises his lowly home. It is the dwelling therefore that above all compels attention, even that of the poet, who cares little in general for realities. In this respect, indeed, the Cricket Is ex- traordinary. Of all our Insects, he alone, on attaining maturity, possesses a fixed abode, the monument of his industry. During the bad season of the year, most of the others burrow or skulk in some temporary refuge, a refuge obtained free of cost and abandoned without regret. Several create marvels, with a view to settling their family: cotton satchels, baskets made of leaves, towers of 306 The Cricket: the Burrow cement. Some carnivorous larvae dwell in permanent ambuscades, where they lie in wait for their prey. The Tiger-beetle, among others, digs itself a perpendicular hole, which it closes with its flat, bronze head. Whoever ventures on the insidious foot- bridge vanishes down the gulf, whose trap- door at once tips up and disappears beneath the feet of the wayfarer. The Ant-lion makes a funnel in the sand. The Ant slides down its very loose slope and is bombarded with projectiles hurled from the bottom of the crater by the hunter, who turns his neck into a catapult. But these are all temporary refuges, nests or traps. The laboriously constructed residence, in which the insect settles down with no inten- tion of moving, either in the happy spring or the woful winter season; the real manor, built for peace and comfort and not as a hunting-box or a nursery: this is known to the Cricket alone. On some sunny, grassy slope he is the owner of a hermitage. While all the others lead vagabond lives, sleeping In the open air or under the casual shelter of a dead leaf, a stone, or the peeling bark of an old tree, he is a privileged person with a permanent address. 307 The Life of the Grasshopper A serious problem Is that of the home. It has been solved by the Cricket, by the Rabbit and, lastly, by man. In my neigh- bourhood, the Fox and the Badger have holes the best part of which is supplied by the Irregularities of the rock. A few re- pairs; and the dug-out is completed. Cleverer than they, the Rabbit builds his house by burrowing wheresoever he pleases, when there is no natural passage that allows him to settle down free of any trouble. The Cricket surpasses all of them. Scorn- ing chance refuges, he always chooses the site of his abode, in well-drained ground, with a pleasant sunny aspect. He refuses to make use of fortuitous cavities, which are Incommodious and rough; he digs every bit of his villa, from the entrance-hall to the back-room. I see no one above him, in the art of house-building, except man; and even man, before mixing mortar to hold stones to- gether, before kneading clay to coat his hut of branches, fought with wild beasts for the possession of a refuge in the rocks or an underground cavern. Then how are the privileges of instinct distributed? Here is one of the humblest, 308 The Cricket: the Burrow able to lodge himself to perfection. He has a home, an advantage unknown to many civilized beings; he has a peaceful retreat, the first condition of comfort; and nobody around him is capable of settling down. Pie has no rivals until you come to ourselves. Whence does he derive this gift? Is he favoured with special tools? No, the Cricket is not an incomparable excavator; in fact, one is rather surprised at the result when one considers the feebleness of his re- sources. Can it be made necessary by the demands of an exceptionally delicate skin? No, among his near kinsmen, other skins, no less sensitive than his, do not dread the open air at all. Can it be a propensity inherent in the anatomical structure, a talent prescribed by the secret promptings of the organism? No, my neighbourhood boasts three other Crickets (Gryllus bimaculatus, DE Geer; G. desertus, Pallas.; G. biirdi^alensis ; I^atr.) ^ who are so like the Field Cricket in appear- ance, colour and structure that, at the first glance, one would take them for him. The first is as large as he is, or even larger. The second represents him reduced to about half 309 The Life of the Grasshopper his size. The third is smaller still. Well, of these faithful copies, these doubles of the Field Cricket, not one knows how to dig him- self a burrow. The Double-spotted Cricket inhabits those heaps of grass left to rot in damp places; the Solitary Cricket roams about the crevices In the dry clods turned up by the gardener's spade ; the Bor- deaux Cricket Is not afraid to make his way into our houses, where he sings discreetly, during August and September, In some dark, cool spot. There Is no object In continuing our quest- Ions : each would meet with no for an an- swer. Instinct, which stands revealed here and disappears there despite organisms alike in all respects, will never tell us Its causes. It depends so little on an Insect's stock of tools that no anatomical detail can explain It to us and still less make us foresee It. The four almost Identical Crickets, of whom one alone understands the art of burrowing, add their evidence to the manifold proofs already supplied; they confirm in a striking fashion our profound Ignorance of the origin of Instinct. Who does not know the Cricket's abode ! Who has not, as a child playing in 310 The Cricket: the Burrow the fields, stopped in front of the hermit's cabin ! However light your footfall, he has heard you coming and has abruptly with- drawn to the very bottom of his hiding- place. When you arrive, the threshold of the house is deserted. Everybody knows the way to bring the skulker out. You insert a straw and move it gently about the burrow. Surprised at what is happening above, tickled and teased, the Cricket ascends from his secret apart- ment; he stops in the passage, hesitates and enquires into things by waving his delicate antennae; he comes to the light and, once outside, he is easy to catch, so greatly have events puzzled his poor head. Should he be missed at the first attempt, he may become more suspicious and obstinately resist the titillation of the straw. In that case, we can flood him out with a glass of water. O those adorable times when we used to cage our Crickets and feed them on a leaf of lettuce, those childish hunting-trips along the grassy paths ! They all come back to me to-day, as I explore the burrows in search of subjects for my studies; they appear to me almost in their pristine freshness when my companion, little Paul, already an expert In 3" The Life of the Grasshopper the tactical use of the straw, springs up sud- denly, after a long trial of skill and pa- tience with the recalcitrant, and, brandishing his closed hand in the air, cries, excitedly: " I've got him, I've got him! " Quick, here's a bag; in you go, my little Cricket ! You shall be petted and pampered ; but mind you teach us something and, first of all, show us your house. It is a slanting gallery, situated in the grass, on some sunny bank which soon dries after a shower. It is nine inches long at most, hardly as thick as one's finger and straight or bent according to the exigencies of the ground. As a rule, a tuft of grass, which is respected by the Cricket when he goes out to browse upon the surrounding turf, half-conceals the home, serving as a porch and throwing a discreet shade over the entrance. The gently-sloping threshold, scrupulously raked and swept, is carried for some distance. This is the belvedere on which, when everything is peaceful round about, the Cricket sits and scrapes his fiddle. The inside of the house is devoid of luxury, with bare and yet not coarse walls. Ample leisure allows the inhabitant to do away with any unpleasant roughness. At the .112 The Cricket: the Eggs end of the passage is the bedroom, the terminal alcove, a little more carefully smoothed than the rest and slightly wider. All said, it is a very simple abode, exceed- ingly clean, free from damp and conforming with the requirements of a well-considered system of hygiene. On the other hand, it is an enormous undertaking, a regular Cy- clopean tunnel, when we consider the modest means of excavation. Let us try to be pre- sent at the work. Let us also enquire at what period the enterprise begins. This obliges us to go back to the egg. Any one wishing to see the Cricket lay p her eggs can do so without making great preparations : all that he w^ants is a little I patience, which, according to Buffon, is 1 genius, but which I, more modestly, will " describe as the observer's chief virtue. In April, or at latest in May, v/e establish iso- lated couples of the insect in flower-pots con- taining a layer of heaped-up earth. Their provisions consist of a lettuce-leaf renewed from time to time. A square of glass covers the retreat and prevents escape. Some extremely interesting facts can be obtained with this simple installation, supple- mented, if need be, wuth a wire-gauze cover, 313 The Life of the Grasshopper the best of all cages. We shall return to this matter. For the moment, let us watch the laying and make sure that the propitious hour does not evade our vigilance. It Is In the first week In June that my as- siduous visits begin to show satisfactory results. I surprise the mother standing mo- tionless, with her ovipositor planted per- pendicularly in the soil. For a long time she remains stationed at the same point, heedless of her Indiscreet caller. At last she with- draws her dibble, removes, more or less per- functorily, the traces of the boring-hole, takes a moment's rest, walks away and starts again somewhere else, now here, now there, all over the area at her disposal. Her be- haviour, though her movements are slower, is a repetition of what the Decticus has shown us. Her egg-laying appears to me to be ended within the twenty-four hours. For greater certainty, I wait a couple of days longer. I then dig up the earth in the pot. The straw-coloured eggs are c^dlnders rounded at both ends and measuring about one-ninth of an Inch In length. They are placed singly in the soil, arranged vertically and grouped in more or less numerous patches, which cor- 314 k The Cricket: the Eggs respond with the successive layings. I find them all over the pot, at a depth of three- quarters of an inch. There are difficulties in examining a mass of earth through a mag- nifying-glass; but, allowing for these difficult- ies, I estimate the eggs laid by one mother at five or six hundred. So large a family is sure to undergo a drastic purging before long. The Cricket's egg is a little marvel of mechanism. After hatching, it appears as an opaque white sheath, with a round and very regular aperture at the top ; to the edge of this a cap adheres, forming a lid. In- stead of bursting anyhow under the thrusts or cuts of the new-born larva, it opens of its own accord along a specially prepared line of least resistance. It became important to observe the curious hatching. About a fortnight after the egg is laid, two large, round, rusty-black eye-dots darken the front end. A little way above these two dots, right at the apex of the cylinder, you see the outline of a thin cir- cular swelling. This is the line of rupture which is preparing. Soon the translucency of the egg enables the observer to perceive the delicate segmentation of the tiny creature 315 The Life of the Grasshopper within. Now is the time to redouble our vigilance and multiply our visits, especially in the morning. Fortune, which loves the persevering, re- wards me for my assiduity. All round this swelling where, by a process of infinite deli- cacy, the line of least resistance has been prepared, the end of the egg^ pushed back by the inmate's forehead, becomes detached, rises and falls to one side like the top of a miniature scent-bottle. The Cricket pops out like a Jack-in-the-box. When he is gone, the shell remains dis- tended, smooth, Intact, pure white, with the cap or lid hanging from the opening. A bird's egg breaks clumsily under the blows of a wart that grows for the purpose at the end of the chick's beak; the Cricket's egg, endowed with a superior mechanism, opens like an Ivory case. The thrust of the In- mate's head Is enough to work the hinge. The hatching of the eggs Is hastened by the glorious weather; and the observer's pa- tience Is not much tried, the rapidity rivalling that of the Dung-beetles. The summer solstice has not yet arrived when the ten couples Interned under glass for the benefit of my studies are surrounded by their 316 The Cricket: the Eggs numerous progeny. The egg-stage, there- fore, lasts just about ten days. I said above that, when the Hd of the ivory case is hfted, a young Cricket pops out. This is not quite accurate. What appears at the opening is the swaddled grub, as yet unrecognizable in a tight-fitting sheath. I expected to see this wrapper, this first set of baby-clothes, for the same reasons that made me anticipate It in the case of the Decticus : " The Cricket," said I to myself, " is born underground. He also sports two very long antennae and a pair of overgrown hind-legs, all of which are cumbrous appendages at the time of the emergence. He must therefore possess a tunic in which to make his exit." My forecast, correct enough in principle, was only partly confirmed. The new-born Cricket does in fact possess a temporary structure; but, so far from employing It for the purpose of hoisting himself outside, he throws off his clothes as he passes out of the To what circumstances are we to attribute this departure from the usual practice ? Per- haps to this : the Cricket's egg stays in the ground for only a few days before hatching; the egg of the Decticus remains there for 317 The Life of the Grasshopper eight months. The former, save for rare exceptions in a season of drought, Hes under a thin layer of dry, loose, unresisting earth; the latter, on the contrary, finds itself in soil which has been caked together by the per- sistent rains of autumn and winter and which therefore presents serious difficulties. More- over, the Cricket is shorter and stouter, less long-shanked than the Decticus. These would appear to be the reasons for the dif- ference between the two Insects in respect of their methods of emerging. The Decticus, born lower down, under a close-packed layer, needs a climbing-costume with which the Cricket Is able to dispense, being less hampered and nearer to the surface and hav- ing only a powdery layer of earth to pass through. Then what is the object of the tights which the Cricket flings aside as soon as he Is out of the egg? I will answer this quest- Ion with another: what Is the object of the two white stumps, the two pale-coloured embryo wings carried by the Cricket under his wing-cases, which are turned Into a great mechanism of sound? They are so insig- nificant, so feeble that the Insect certainly makes no use of them, any more than the 318 The Cricket: the Eggs Dog utilizes the thumb that hangs hmp and lifeless at the back of his paw. Sometimes, for reasons of symmetry, the walls of a house are painted with imitation windows to balance the other windows, which are real. This is done out of respect for order, the supreme condition of the beau- tiful. In the same way, life has its sym- metries, its repetitions of a general proto- type. When abolishing an organ that has ceased to be employed, it leaves vestiges of it to maintain the primitive arrangement. The Dog's rudimentary thumb predicates the five-fingered hand that characterizes the higher animals; the Cricket's wing-stumps are evidence that the insect would normally be capable of flight; the moult undergone on the threshold of the egg is reminiscent of the tight-fitting wrapper needed for the laborious exit of the Locustldae born underground. They are so many symmetrical superfluities, so many remains of a law that has fallen into disuse but never been abrogated. As soon as he Is deprived of his delicate tunic, the young Cricket, pale all over, al- most white, begins to battle with the soil overhead. He hits out with his mandibles; he sweeps aside and kicks behind him the 319 The Life of the Grasshopper powdery obstruction, which offers no resist- ance. Behold him on the surface, amidst the joys of the sunlight and the perils of conflict with the living, poor, feeble creature that he is, hardly larger than a Flea. In twenty-four hours he colours and turns Into a magnificent blackamoor, whose ebon hue vies with that of the adult insect. All that remains of his original pallor is a white sash that girds his chest and reminds us of a baby's leading-string. Very nimble and alert, he sounds the surrounding space with his long, quivering antennae, runs about and jumps with an impetuosity in which his future obesity will forbid him to indulge. This is also the age when the stomach is still delicate. What sort of food does he need? I do not know. I offer him the adult's treat, tender lettuce-leaves. He scorns to touch them, or perhaps he takes mouthfuls so exceedingly small that they escape me. In a few days, with my ten households, I find myself overwhelmed with family cares. What am I to do with my five or six thousand Crickets, a pretty flock, no doubt, but Impossible to rear in my ignorance of the treatment required? I will 320 The Cricket: the Eggs set you at liberty, my little dears; I will entrust you to nature, the sovran nurse. Thus it comes to pass. I release my legions in the enclosure, here, there and everywhere, in the best places. What a con- cert I shall have outside my door next year, if they all turn out well! But no, the sym- phony will probably be one of silence, for the § savage pruning due to the mother's fertility is bound to come. All that I can hope for is that a few couples may survive extermina- L;, tion. ' As in the case of the young Praying Mantes, the first that hasten to this manna and the most eager for the slaughter are the little Grey Lizard and the Ant. The latter, loathsome freebooter that she is, will, I fear, not leave me a single Cricket in the garden. She snaps up the poor little crea- tures, eviscerates them and gobbles them down at frantic speed. Oh, the execrable wretch! And to think that we place the Ant In the front rank of insects ! Books are written in her honour and the stream of eulogy never ceases; the naturalists hold her in the greatest esteem and add daily to her reputation, so true is it, among animals as among men, that of the 321 The Life of the Grasshopper various ways of making history, the surest way Is to do harm to others/ Nobody asks after the Dung-beetle and the Necrophorus," Invaluable scavengers both, whereas everybody knows the Gnat, that drinker of men's blood; the Wasp, that hot-tempered swashbuckler, with her poi- soned dagger; and the Ant, that notorious evil-doer, who. In our southern villages, saps and Imperils the rafters of a dwelling with the same zest with which she devours a fig. I need not trouble to say more : every one Vv^ll discover In the records of mankind similar instances of usefulness ignored and frightfulness exalted. The massacre Instituted by the Ants and other exterminators Is so great that my erst- while populous colonies In the enclosure be- come too small to enable me to continue my observations; and I am driven to have re- course to Information outside. In August, among the fallen leaves, in those little oases where the grass has not been wholly scorched by the sun, I find the young Cricket already rather big, black all over like the adult, * For the author's only essay on Ants, cf. The Mason- bees: chap. vi. — Translator's Note. ' Or Burying-beetle. — Translator's Note. 322 The Cricket: the Burrow with not a vestige of the white girdle of his early days. He has no domicile. The shelter of a dead leaf, the cover of a flat stone are enough for him; they represent the tents of a nomad who cares not where he lays his head. This vagabond life continues until the middle of autumn. It is then that the Yellow-winged Sphex ^ hunts down the wan- derers, an easy prey, and stores her bag of Crickets underground. She decimates those who have survived the Ants' devastating raids. A settled dwelling, dug a few weeks before the usual time, would save them from the spoilers. The sorely-tried victims do not think of it. The bitter experience of the centuries has taught them nothing. Though already strong enough to dig a protecting burrow, they remain invincibly faithful to their ancient customs and would go on roam- ing though the Sphex stabbed the last of their race. It is at the close of October, when the first cold weather threatens, that the burrow is taken in hand. The work is very simple, judging by the little that my observation of * Cf. The Hunting Wasps: chaps, iv to vii. — Trans- lator's Note. 323 The Life of the Grasshopper the caged insect has shown me. The dig- ging is never done at a bare point in the pan, but always under the shelter of a with- ered lettuce-leaf, some remnant of the food provided. This takes the place of the grass screen that seems indispensable to the secrecy of the establishment. The miner scrapes with his fore-legs and uses the pincers of his mandibles to extract the larger bits of gravel. I see him stamp- ing with his powerful hind-legs, furnished with a double row of spikes; I see him raking the rubbish, sweeping it backwards and spreading it slantwise. There you have the method in its entirety. The work proceeds pretty quickly at first. In the yielding soil of my cages, the digger disappears underground after a spell that lasts a couple of hours. He returns to the entrance at intervals, always backwards and always sweeping. Should he be overcome with fatigue, he takes a rest on the threshold of his half-finished home, with his head out- side and his antennae waving feebly. He goes in again and resumes work with pincers and rakes. Soon the periods of repose be- come longer and wear out my patience. The most urgent part of the work Is done. 324 The Cricket: the Burrow Once the hole is a couple of Inches deep, it suffices for the needs of the moment. The rest will be a long-winded business, resumed in a leisurely fashion, a little one day and a little the next; the hole will be made deeper and wider as demanded by the inclemencies of the weather and the growth of the insect. Even in winter, if the temperature be mild and the sun playing over the entrance to the dwelling, it is not unusual to see the Cricket shooting out rubbish, a sign of repairs and fresh excavations. Amidst the joys of spring, the upkeep of the building still con- tinues. It is constantly undergoing improve- ments and repairs until the owner's decease. April comes to an end and the Cricket's song begins, at first In rare and shy solos, soon developing into a general symphony In which each clod of turf boasts its performer. I am more than inclined to place the Cricket at the head of the spring choristers. In our waste lands, when the thyme and the lavender are gaily flowering, he has as his partner the Crested Lark, who rises like a lyrical rocket, his throat swelling with notes, and from the sky, invisible in the clouds, sheds his sweet music upon the fallows. Down below the Crickets chant the responses. Their 32':, The Life of the Grasshopper song Is monotonous and artless, but so well- suited, In Its very crudity, to the rustic glad- ness of renascent life ! It Is the hosanna of the awakening, the sacred alleluia under- stood by swelling seed and sprouting blade. Who deserves the palm In this duet? I should award It to the Cricket/ He sur- passes them all, thanks to his numbers and his unceasing note. Were the Lark to fall silent, the fields blue-grey with lavender, swinging Its fragrant censers before the sun. would still receive from this humble chorister a solemn celebration. 326 CHAPTER XVI THE CRICKET: THE SONG; THE PAIRING TN steps anatomy and says to the Cricket, •^ bluntly : " Show us your musical-box/' Like all things of real value, it is very simple; it is based on the same principle as that of the Grasshoppers: a bow with a hook to it and a vibrating membrane. The right wing-case overlaps the left and covers it almost completely, except where it folds back sharply and encases the insect's side. It is the converse of what we see in the Green Grasshopper, the Decticus, the Ephip- piger and their kinsmen. The Cricket is right-handed, the others left-handed. The two wing-cases have exactly the same structure. To know one is to know the other. Let us describe the one on the right. It is almost flat on the back and slants sud- denly at the side In a right-angled fold, encircling the abdomen with a pinion which 327 The Life of the Grasshopper has delicate, parallel veins running in an oblique direction. The dorsal surface has stronger and more prominent nervures, of a deep-black colour, which, taken together, form a strange, complicated design, bearing some resemblance to the hieroglyphics of an Arabic manuscript. By holding it up to the light, one can see that it is a very pale red, save for two large adjoining spaces, a larger, triangular one in front and a smaller, oval one at the back. Each is framed in a prominent nervure and scored with faint wrinkles. The first, more- over, is strengthened With four or five chevrons ; the second with only one, which is bow-shaped. These two areas represent the Grasshoppers' mirror; they constitute the sounding-areas. The skin is finer here than elsewhere and transparent, though of a somewhat smoky tint. The front part, which is smooth and slightly red in hue, is bounded at the back by two curved, parallel veins, having betv/een them a cavity containing a row of five or six little black wrinkles that look like the rungs of a tiny ladder. The left wing-case presents an exact duplicate of the right. The wrinkles constitute the friction-nerv- 328 The Cricket: the Song ures which intensify the vibration by increas- ing the number of the points that are touched by the bow. On the lower surface, one of the two veins that surround the cavity with the rungs be- comes a rib cut into the shape of a hook. This is the bow. I count in it about a hun- dred and fifty triangular teeth or prisms of exquisite geometrical perfection. It is a fine instrument indeed, far superior to that of the Decticus. The hundred and fifty prisms of the bow, biting into the rungs of the opposite wing-case, set the four drums in motion at one and the same time, the lower pair by direct friction, the upper pair by the shaking of the friction-apparatus. What a rush of sound! The Decticus, en- dowed with a single paltry mirror, can be heard just a few steps away; the Cricket, possessing four vibratory areas, throws his ditty to a distance of some hundreds of yards. He vies with the Cicada in shrillness, without having the latter's disagreeable harshness. Better still : this favoured one knows how to modulate his song. The wing-cases, as we said, extend over either side in a wide fold. These are the dampers 329 The Life of the Grasshopper which, lowered to a greater or lesser depth, alter the intensity of the sound and, accord- ing to the extent of their contact with the soft abdomen, allow the insect to sing mezza voce at one time and fortissimo at another. The exact similarity of the two wing- cases is worthy of attention. I can see clearly the function of the upper bow and the four sounding-areas which it sets in mo- tion; but what is the good of the lower one, the bow on the left wing? Not resting on anything, it has nothing to strike with its hook, which is as carefully toothed as the other. It is absolutely useless, unless the apparatus can invert the order of its two parts and place that above which was below. After such an Inversion, the perfect sym^- metry of the instrument would cause the necessary mechanism to be reproduced in every respect and the insect would be able to stridulate with the hook which is at pre- sent unemployed. It would scrape away as usual with Its lower fiddlestick, now become the upper; and the tune would remain the same. Is this permutation within Its power? Can the Insect use both pot-hooks, changing from one to the other when It grows tired, 330 The Cricket: the Song vv^hlch would mean that it could keep up its music all the longer? Or are there at least some Crickets who are permanently left- handed? I expected to find this the case, because of the absolute symmetry of the wing-cases. Observation convinced me of the contrary. I have never come across a Cricket that failed to conform with the ge- neral rule. All those whom I have examined — and they are many — without a single ex- ception carried the right wing-case above the left Let us try to interfere and to bring about by artifice what natural conditions refuse to show us. Using my forceps, very gently, of course, and without straining the wing-cases, I make these overlap the opposite way. This result is easily obtained with a little dex- terity and patience. The thing is done. Everything is in order. There is no disloca- tion at the shoulders; the membranes are without a crease. Things could not be better- arranged under normal conditions. Was the Cricket going to sing, with his inverted instrument? I was almost expect- ing it, appearances were so much in its favour; but I was soon undeceived. The insect submits for a few moments; then, find- 331 The Life of the Grasshopper Ing the Inversion uncomfortable, It makes an effort and restores the Instrument to Its regular position. In vain I repeat the opera- tion: the Cricket's obstinacy triumphs over mine. The displaced wing-cases always re- sume their normal arrangement. There is nothing to be done In this direction. Shall I be more successful If I make my attempt while the wing-cases are still Im- mature? At the actual moment, they are stiff membranes, resisting any changes. The fold Is already there; It Is at the outset that the material should be manipulated. What shall we learn from organs that are quite new and still plastic, if we Invert them as soon as they appear? The thing is worth trying. For this purpose, I go to the larva and watch for the moment of its metamorphosis, a sort of second birth. The future wings and wing-cases form four tiny flaps which, by their shape and their scantiness, as well as by the way in which they stick out In dif- ferent directions, remind me of the short jackets worn by the Auvergne cheese-makers. I am most assiduous In my attendance, lest I should miss the propitious moment, and at last have a chance to witness the moult- 332 The Cricket: the Song Ing. In the early part of May, at about eleven in the morning, a larva casts off its rustic garments before my eyes. The trans- formed Cricket is now a reddish brown, all but the wings and wing-cases, which are beautifully white. Both wings and wing-cases, which only issued from their sheaths quite recently, are no more than short, crinkly stumps. The former remain in this rudimentary state, or nearly so. The latter gradually develop bit by bit and open out; their inner edges, with a movement too slow to be perceived, meet one another, on the same plane and at the same level. There is no sign to tell us which of the two wing-cases will overlap the other. The two edges are now touching. A few moments longer and the right will be above the left. This is the time to intervene. With a straw I gently change the position, bringing the left edge over the right. The insect protests a little and disturbs my manoeuvring. I insist, while taking every possible care not to endanger these tender organs, which look as though they were cut out of wet tissue-paper. And I am quite suc- cessful: the left wing-case pushes forward above the right, but only very little, barely 333 The Life of the Grasshopper a twenty-fifth of an Inch. We will leave it alone : things will now go of themselves. They go as well as one could wish, in fact. Continuing to spread, the left wing- case ends by entirely covering the other. At three o'clock in the afternoon, the Cricket has changed from a reddish hue to black, but the wing-cases are still white. Two hours more and they also will possess the normal colouring. It is over. The wing-cases have come to maturity under the artificial arrangement; they have opened out and moulded them- selves according to my plans; they have taken breadth and consistency and have been born, so to speak, in an inverted position. As things now are, the Cricket Is left-handed. Will he definitely remain so? It seems to me that he will; and my hopes rise higher on the morrow and the day after, for the wing-cases continue, without any trouble. In their unusual arrangement. I expect soon to see the artist wield that particular fiddle- stick which the members of his family never employ. I redouble my watchfulness, so as to witness his first attempt at playing the violin. On the third day, the novice makes a 334 The Cricket: the Song start. A few brief grating sounds are heard, the noise of a machine out of gear shifting its parts back into their proper order. Then the song begins, with its accustomed tone and rhythm. Veil your face, O foolish experimenter, overconfident in your mischievous straw! You thought that you had created a new type of instrumentalist; and you have ob- tained nothing at all. The Cricket has thwarted your schemes : he is scraping with his right fiddlestick and always will. With a painful effort, he has dislocated his shoul- ders, which were made to mature and harden the wrong way; and, In spite of a set that seemed definite, he has put back on top that which ought to be on top and underneath that which ought to be underneath. Your sorry science tried to make a left-handed player of him. He laughs at your devices and settles down to be right-handed for the rest of his life. Franklin left an eloquent plea on behalf of the left hand, which, he considered, de- served as careful training as Its fellow. What an Immense advantage It would be thus to have two servants each as capable as the other! Yes, certainly; but, except for 335 The Life of the Grasshopper a few rare Instances, is this equahty of strength and skill in the two hands possible? The Cricket answers no : there Is an ori- ginal weakness In the left side, a want of balance, Vv'hich habit and training can to a certain extent correct, but which they can never cause wholly to disappear. Though shaped by a training which takes It at its birth and moulds and solidifies it on the top of the other, the left w'Ing-case none the less resumes the lower position when the Insect tries to sing. As to the cause of this original inferiority, that is a problem which belongs to embryogenesls. My failure confirms the fact that the left wing-case Is unable to make use of Its bow, even when supplemented by the aid of art. Then what Is the object of that hook whose exquisite precision yields In no respect to that of the other? We might appeal to reasons of symmetry and talk about the repetition of an archetypal design, as I, for want of a better argument, did just now in the matter of the cast raiment which the young Cricket leaves on the threshold of his ovular sheath; but I prefer to confess that this would be but the semblance of an explanation, wrapped up in specious language. For the Decticus, 33^ The Cricket: the Song the Grasshopper and the other Locustldae would come and show us their wing-cases, one with the bow only, the other with the mirror, and say: , " Why should the Cricket, our near kins- man, be symmetrical, whereas all of us Locustidae, without exception, are asym- metrical? " There is no valid answer to their objec- tion. Let us confess our ignorance and humbly say: " I do not know." It wants but a Midgets wing to confound our proudest theories. Enough of the instrument; let us listen to the music. The Cricket sings on the thresh- old of his house, in the cheerful sunshine, never indoors. The wing-cases, lifted in a double inclined plane and now only partly covering each other, utter their stridulant cri'Cri in a soft tremolo. It is full, sonorous, nicely cadenced and lasts indefinitely. Thus are the leisures of solitude beguiled all through the spring. The anchorite at first sings for his own pleasure. Glad to be alive, he chants the praises of the sun that shines upon him, the grass that feeds him, the peaceful retreat that harbours him. The 337 The Life of the Grasshopper first object of his bow is to hymn the bless- ings of Hfe. The hermit also sings for the benefit of his fair neighbours. The Cricket's nuptials would, I warrant, present a curious scene, if it were possible to follow their details far from the commotions of captivity. To seek an opportunity would be labour lost, for the insect is very shy. I must await one. Shall I ev^er find it? I do not despair, in spite of the extraordinary difficulty. For the mo- ment, let us be satisfied with what we can learn from probability and the vivarium. The two sexes dwell apart. Both are ex- tremely domestic in their habits. Whose business is it to make a move? Does the caller go In search of the called? Does the serenaded one come to the serenader? If, at pairing-time, sound were the sole guide where homes are far apart, it would be necessary for the silent partner to go to the noisy one's trysting-place. But I Imagine that, in order to save appearances — and this accords with what I learn from my prisoners — the Cricket has special faculties that guide him towards his mute lady-love. When and how is the meeting effected? T suspect that things take place in the friendly 338 The Cricket: the Pairing gloaming and upon the very threshold of the bride's home, upon that sanded esplanade, that state courtyard, which lies just outside the entrance. A nocturnal journey like this, at some twenty paces' distance, is a serious under- taking for the Cricket. When he has ac- complished his pilgrimage, how will he, the stay-at-home, with his imperfect knowledge of topography, find his own house again? To return to his Penates must be impossible. He roams, I fear, at random, with no place to lay his head. He has neither the time nor the heart to dig himself the new burrow which would be his salvation; and he dies a wretched death, forming a savoury mouth- ful for the Toad on his night rounds. His visit to the lady Cricket has cost him his home and his life. What does he care ! He has done his duty as a Cricket. This is how I picture events when I com- bine the probabilities of the open country with the realities of the vivarium. I have several couples in one cage. As a rule, my captives refrain from digging themselves a dwelling. The hour has passed for any long waiting or long wooing. They wander about the enclosed space, without troubling about 339 The Life of the Grasshopper a fixed home, or else lie low under the shelter of a lettuce-leaf. Peace reigns in the household until the quarrelsome instincts of pairing-time break out. Then affrays between suitors are fre- quent and lively, though not serious. The two rivals stand face to face, bite each other in the head, that solid, fang-proof helmet, roll each other over, pick themselves up and separate. The vanquished Cricket makes off as fast as he can; the victor insults him with a boastful ditty; then, moderating his tone, he veers and tacks around the object of his desires. He makes himself look smart and, at the same time, submissive. Gripping one of his antennae with a claw, he takes it in his mandi- bles to curl it and grease it with saliva. With his long spurred and red-striped hind-legs, he stamps the ground impatiently and kicks out at nothing. His emotion renders him dumb. His wing-cases, it is true, quiver rap- idly, but they give forth no sound, or at most an agitated rustling. A vain declaration! The female Cricket runs and hides herself In a curly bit of let- tuce. She lifts the curtain a little, however, and looks out and wishes to be seen. 340 The Cricket: the Pairing Et fugit ad salices; et se cupit ante videri,^ said the delightful eclogue, two thousand years ago. Thrice-consecrated strategy of love, thou art everywhere the same ! The song is resumed, Intersected by si- lences and murmuring quavers. Touched by so much passion, Galatea, I mean Dame Cricket, issues from her hiding-place. The other goes up to her, suddenly spins round, turns his back to her and flattens his ab- domen against the ground. Crawling back- wards, he makes repeated efforts to slip un- derneath. The curious backward mancEuvre at last succeeds. Gently, my little one, gently! Discreetly flattened out, you man- age to slide under. That's done it! We have our couple. A spermatophore, a granule smaller than a pin's head, hangs where it ought to. The meadows will have their Crickets next year. The laying of the eggs follows soon after. Then this cohabitation in couples in a cage often brings about domestic quarrels. The father is knocked about and crippled; his * " Then tripping to the woods the wanton hies And wishes to be seen before she flies." — Virgil, Pastorals: book i. ; Dryden's translation. 341 The Life of the Grasshopper violin is smashed to bits. Outside my cells, in the open fields, the hen-pecked husband is able to take to flight; and that indeed is what he appears to do, not without good reason. This ferocious aversion of the mother for the father, even among the most peaceable, gives food for thought. The sweetheart of but nov/, if he come within reach of the lady's teeth, is eaten more or less; he does not escape from the final interviews without leaving a leg or two and some shreds of wing-cases behind him. Locusts and Crickets, those lingering representatives of a bygone world, tell us that the male, a mere secondary wheel in life's original mechan- ism, has to disappear at short notice and make room for the real propagator, the real worker, the mother. Later, in the higher order of creation, sometimes even among insects, he is awarded a task as a collaborator; and nothing better could be desired: the family must needs gain by it. But the Cricket, faithful to the old traditions, has not yet got so far. There- fore the object of yesterday's longing be- comes to-day an object of hatred, ill-treated, disembowelled and eaten up. 342 The Cricket: the Pairing Even when free to escape from his pugnacious mate, the superannuated Cricket soon perishes, a victim to hfe. In June, all my captives succumb, some dying a natural, others a violent death. The mothers survive for some time in the midst of their newly-hatched family. But things happen differently when the males have the advan- tage of remaining bachelors : they then enjoy a remarkable longevity. Let me relate the facts. We are told that the music-loving Greeks used to keep Cicadae in cages, the better to enjoy their singing. I venture to disbelieve the whole story. In the first place, the harsh clicking of the Cicadae, when long continued at close quarters, is a torture to ears that are at all delicate. The Greeks' sense of hearing was too well-disciplined to take pleasure in such raucous sounds away from the general concert of the fields, which is heard at a distance. In the second place, it is absolutely im- possible to bring up Cicadae in captivity, un- less we cover over an olive-tree or a plane- tree, which would supply us with a vivarium very difficult to instal on a window-sill. A single day spent in a cramped enclosure 343 The Life of the Grasshopper would make the high-flying insect die of boredom. Is it not possible that people have con- fused the Cricket with the Cicada, as they also do the Green Grasshopper? With the Cricket they would be quite right. He is one who bears captivity gaily: his stay-at- home ways predispose him to it. He lives happily and whirrs without ceasing in a cage no larger than a man's fist, provided that we serve him with his lettuce -leaf every day. Was It not he whom the small boys of Athens reared In little wire cages hanging on a window-frame ? Their successors In Provence and all over the south have the same tastes. In the towns, a Cricket becomes the child's treasured pos- session. The insect, petted and pampered, tells him In its ditty of the simple joys of the country. Its death throws the whole household Into a sort of mourning. Well, these recluses, these compulsory celibates, live to be patriarchs. They keep fit and well long after their cronies In the fields have succumbed; and they go on sing- ing till September. Those additional three months, a long space of time, double their existence In the adult form. 344 \ The Cricket: the Pairing The cause of this longevity is obvious. Nothing wears one out so quickly as hfe. The wild Crickets have gaily spent their re- serves of energy on the ladies; the more fervent their ardour, the speedier their dis- solution. The others, their Incarcerated kinsmen, leading a very quiet life, have ac- quired a further period of existence by reason of their forced abstinence from too costly joys. Having neglected to perform the superlative duty of a Cricket, they ob- stinately refuse to die until the very last moment. A brief study of the three other Crickets of my neighbourhood has taught me nothing of any Interest. Possessing no fixed abode, no burrow, they wander about from one tem- porary shelter to another, under the dry grass or in the cracks of the clods. They all carry the same musical Instrument as the Field Cricket, with slight variations of de- tail. Their song Is much alike in all cases, allowing for differences of size. The small- est of the family, the Bordeaux Cricket, strldulates outside my door, under the cover of the box borders. He even ventures Into the dark corners of the kitchen, but his song is so faint that It takes a very attentive ear 345 The Life of the Grasshopper to hear It and to discover at last where the insect Hes hidden. In our part of the world, we do not have the House Cricket, that denizen of bakers' shops and rural fireplaces. But, though the crevices under the hearthstones in my village are silent, the summer nights make amends by filling the country-side with a charming symphony unknown In the north. Spring, during its sunniest hours, has the Field Cricket as its musician; the calm summer nights have the Italian Cricket (CEcanthus pellucens, Scop.). One diurnal, the other nocturnal, they share the fine weather be- tween them. By the time that the first has ceased to sing, it is not long before the other begins his serenade. The Italian Cricket has not the black dress and the clumsy shape characteristic of the family. He is, on the contrary, a slender, fragile Insect, quite pale, almost white, as beseems his nocturnal habits. You are afraid of crushing him, If you merely take him in your fingers. He leads an aerial existence on shrubs of every kind, or on the taller grasses; and he rarely descends to earth. His song, the sweet music of the still, hot evenings from July to October, begins at 346 The Cricket: the Song sunset and continues for the best part of the night. This song is known to everybody here, for the smallest clump of bushes has its orches- tra. It is heard even in the granaries, into which the insect sometimes strays, attracted by the fodder. But the pale Cricket's ways are so mysterious that nobody knows exactly the source of the serenade, which Is very erroneously ascribed to the Common Black Cricket, who at this period is quite young and silent. The song is a soft, slow gri-i-i, gri-i-i, which is rendered more expressive by a slight tremolo. On hearing it, we divine both the extreme delicacy and the size of the vibrating membranes. If nothing happen to disturb the insect, settled in the lower leaves, the sound remains unaltered; but, at the least noise, the executant becomes a ventriloquist. You heard him here, quite close, in front of you ; and now, all of a sudden, you hear him over there, fifteen yards away, continuing his ditty softened by distance. You move across. Nothing. The sound comes from the original place. No, it doesn't, after all. This time, it Is coming from over there, on the left, or rather frorr? 347 The Life of the Grasshopper the right; or is it from behind? We are absolutely at a loss, quite unable to guide ourselves by the ear towards the spot where the insect is chirping. It needs a fine stock of patience and the most minute precautions to capture the singer by the light of a lantern. The few speci- mens caught under these conditions and caged have supplied me with the little that I know about the musician who Is so clever at baffling our ears. The wing-cases are both formed of a broad, dry, diaphanous membrane, fine as a white onion-skin and capable of vibrating throughout Its whole area. They are shaped like a segment of a circle thinning towards the upper end. This segment folds back at right angles along a prominent longitudinal vein and forms a flap which encloses the insect's side when at rest. The right wing-case lies above the left. Its inner edge bears underneath, near the root, a knob which is the starting-point of five radiating veins, of which two run up- wards, two downwards and the fifth almost transversely. The last-named, which Is slightly reddish, is the main part, in short the bow, as is shown by the fine notches cut 348 The Cricket: the Song across It. The rest of the wing-case presents a few other veins of minor importance, which keep the membrane taut without form- ing part of the friction-apparatus. The left or lower wing-case is similar^ constructed, with this difference that the bow, the knob and the veins radiating from it now occupy the upper surface. We find, more- over, that the two bows, the right and the left, cross each other obliquely. When the song has its full volume, the wing-cases, raised high up and resembling a pair of large gauze sails, touch only at their inner edges. Then the two bows fit into each other slantwise and their mutual fric- tion produces the sonorous vibration of the two stretched membranes. The sound appears to be modified accord- ing as the strokes of each bow bear upon the knob, which is Itself wrinkled, on the op- posite wing-case, or upon one of the four smooth radiating veins. This would go some way towards explaining the Illusions produced by music which seems to come from here, there and everywhere when the timid insect becomes distrustful. The Illusion of loud or soft, open or muf- fled sounds and consequently of distance, 349 The Life of the Grasshopper which forms the chief resource of the ven- triloquist's art, has another, easily discovered source. For the open sounds, the wing- cases are raised to their full height; for the muffled sounds, they are lowered more or less. In the latter position, their outer edges press to a varying extent upon the Insect's yielding sides, thus more or less decreasing the vibratory surface and reducing the volume of sound. A gentle touch with one's finger stifles the sound of a ringing wine-glass and changes it Into a veiled. Indefinite note that seems to come from afar. The pale Cricket knows this acoustic secret. He misleads those who are hunting for him by pressing the edges of his vibrating flaps against his soft abdomen. Our musical Instruments have their dampers, their sourdines; that of CEcanthus pellucens vies with and surpasses them In the simpli- city of its method and the perfection of its results. The Field Cricket and his kinsmen also employ the sourdine by clasping their ab- domen higher or lower with the edge of their wing-cases; but none of them obtains from this procedure such deceptive effects as those of the Italian Cricket. 350 The Cricket: the Song In addition to this illusion of distance, which, at the faintest sound of footsteps, is constantly taking us by surprise, we have the purity of the note, with its soft tremolo. I know no prettier or more limpid insect song, heard in the deep stillness of an August evening. How often, per arnica silentia lima,^ have I lain down on the ground, screened by the rosemary-bushes, to listen to the delicious concert of the harmas! " The nocturnal Cricket swarms in the en- closure. Every tuft of red-flowering rock- rose has its chorister; so has every clump of lavender. The bushy arbutus-shrubs, the turpentine-trees, all become orchestras. And, with its clear and charming voice, the whole of this little world is sending questions and responses from shrub to shrub, or rather, indifferent to the hymns of others, chanting its gladness for itself alone. High up, immediately above my head, the Swan stretches Its great cross along * " Safe under covert of the silent night And guided by the imperial galley's light." — Virgil, Mneid: book ii. ; Dryden's translation.

The Life of the Fly: chap. i. — Translator's Note. 351 The Life of the Grasshopper the Milky Way; below, all around me, the insects' symphony rises and falls. The in- finitesimal telling its joys makes me forget the pageant of the stars. We know nothing of those celestial eyes which look down upon us, placid and cold, with scintillations that are like blinking eyelids. Science tells us of their distance, their speed, their mass, their volum^e; it overwhelms us with enorm.ous figures, stupefies us with immensities; but it does not succeed in stirring a fibre within us. Why? Because it lacks the great secret, that of life. What is there up there ? What do those suns warm ? Worlds like ours, reason declares; planets whereon life revolves in infinite variety. It is a superb conception of the universe, but, when all is said, only a conception, not supported by obvious facts, those supreme proofs within the reach of all. The probable, the ex- tremely probable, is not the manifest, which forces itself upon us irresistibly and leaves no room for doubt. In your company, on the contrary, O my Crickets, I feel the throbbing of life, which is the soul of our lump of clay; and that is why, under my rosemary-hedge, I give but an absent glance at the constellation of the 352 The Cricket: the Song Swan and devote all my attention to your serenade ! A dab of animated glair, capable of pleasure and of pain, surpasses in interest the immensity of brute matter. 353 CHAPTER XVII THE LOCUSTS: THEIR FUNCTION; THEIR ORGAN OF SOUND "IV/flND you are ready, children, to- -*-~-*- morrow morning, before the sun gets too hot: we are going Locust-hunting." This announcement throws the household into great excitement at bed-time. What do my little helpmates see in their dreams? Blue wings, red wings, suddenly flung out f anwise ; long, saw-toothed legs, pale-blue or pink, which kick out when we hold their owners in our fingers ; great shanks acting as springs that make the insect leap forward like a projectile shot from some dwarf catapult hidden in the grass. What they behold in sleep's sweet magic lantern I also happen to see. Life lulls us with the same simple things in its first stages and its last. If there be one peaceful and safe form of hunting, one that comes within the powers of 354 The Locusts: their Function old age and childhood alike, it is Locust- hunting. Oh, what dehcious mornings we owe to it! What happy moments when the mulberries are black and allow my assistants to go pilfering here and there in the bushes I What memorable excursions on the slopes covered with sparse grass, tough and burnt yellow by the sun ! I retain a vivid recollec- tion of all this; and my children will do the same. Little Paul has nimble legs, a ready hand and a piercing eye. He inspects the clumps of everlastings where the Tryxalis solemnly nods his sugar-loaf head; he scrutinizes the bushes out of which the big Grey Locust suddenly flies like a little bird surprised by the hunter. Great disappointment on the part of the latter, who, after first rushing off at full speed, stops and gazes in wonder at this mock Swallow flying far away. He will have better luck another time. We shall not go home without a few of those magnificent prizes. Younger than her brother, Marie Pauline patiently watches for the Italian Locust, with his pink wings and carmine hind-legs; but she really prefers another jumper, the most elegantly attired of all. Her favourite wears 355 The Life of the Grasshopper a St. Andrew's cross on the small of his back, which is marked by four white, slanting stripes. His livery has patches of verdigris, the exact colour of the patina on old bronze medals. With her hand raised in the air, ready to swoop down, she approaches very softly, stooping low. Whoosh 1 That's done it! Quick, a screw of paper to receive the treasure, which, thrust head first into the opening, plunges with one bound to the bottom of the funnel. Thus are our bags distended one by one; thus are our boxes filled. Before the heat becomes too great to bear, v/e are in possess- ion of a number of varied specimens which, raised in captivity, will perhaps teach us something, if we know how to question them. Thereupon we go home again. The Lo- cust has made three people happy at a small cost. The first question that I put to my board- ers is this : " What function do you perform in the fields?" You have a bad reputation, I know; the text-books describe you as noxious. Do you deserve this reproach? I take the liberty of doubting it, except, of course, in the case of 356 The Locusts: their Function the terrible ravagers who form the scourge of Africa and the east. The ill repute of those voracious eaters has left its mark on you all, though I look upon you as much more useful than injuri- ous. Never, so far as I know, have our peasants complained of you. What damage could they lay to your charge ? You nibble the tops of the tough grasses which the Sheep refuses to touch; you prefer the lean swards to the fat pastures; you browse on sterile land where none but you would find the wherewithal to feed himself; you live upon what could never be used without the aid of your healthy stomach. Besides, by the time that you frequent the fields, the only thing that might tempt you, the green wheat, has long since yielded its grain and disappeared. If you happen to get into the kitchen-gardens and levy toll on them to some slight extent, it is not a rank offence. A man can console himself for a piece bitten out of a leaf or two of salad. To measure the importance of things by the foot-rule of one's own turnip-patch is a horrible method, which makes us forget the essential for the sake of a trivial detail. The short-sighted man would upset the order of 357 The Life of the Grasshopper the universe rather than sacrifice a dozen plums. If he thinks of the insect at all, it is only to speak of its extermination. Fortunately, this is not and never will be in his power. Look at the consequences, for Instance, of the disappearance of the Lo- cust, who is accused of stealing a few crumbs from earth's rich table. In September and October, the Turkeys are driven into the stubble-fields, under the charge of a child armed with two long reeds. The expanse over which the gobbling flock slowly spreads is bare, dry and burnt by the sun. At the most, a few ragged thistles raise their be- lated heads. What do the birds do in a desert like this, simply reeking with famine? They cram themselves, in order to do honour to the Christmas table; they wax fat; their flesh becomes firm and appetizing. With what, pray? With Locusts, whom they snap up here and there, a delicious stufl^ng for their greedy crops. This autumnal manna, which costs nothing and is richly flavoured, contributes to the elaboration and the im- provement of the succulent roast that will be so largely eaten on the festive evening. When the Guinea-fowl, that domesticated game-bird, roams around the farm, uttering 3S8 The Locusts: their Function her rasping note, what is it that she seeks? Seeds, no doubt, but, above all things, Lo- custs, who puff her out under the wings with a pad of fat and give greater flavour to her flesh. The Hen, much to our advantage, is just as fond of them. She well knows the virtues of that dainty dish, which acts as a tonic and increases her laying-capacity. When left at liberty, she hardly ever fails to lead her family to the stubble-fields, so that they may learn how to snap up the exquisite mouthful deftly. In fact, all the denizens of the poultry-yard, when free to wander about at will, owe to the Locust a valuable addition to their diet. It becomes a much more important matter outside our domestic fowls. If you are a sportsman, if you are able to appreciate the value of the Red-legged Partridge, the glory of our southern hills, open the crop of the bird which you have just brought down. You will see that it contains a splendid cer- tificate to the services rendered by the much- maligned insect. You will find it, nine times out of ten, more or less crammed with Lo- custs. The Partridge dotes on them, pre- fers them to seed as long as he is able to 359 The Life of the Grasshopper catch them. This highly-flavoured, substan- tial, stimulating fare would almost make him forget the existence of seeds, if it were only there all the year round. Let us now consult the Illustrious black- footed tribe, so warmly celebrated by Tous- serel.^ The head of the family is the Wheat- ear, the Ciil-blanc," as the Provencal calls him, who grows disgracefully fat In Septem- ber and supplies delicious material for the skewer. At the time when I used to indulge in ornithological expeditions, I made a practice of jotting down the contents of the birds' crops and gizzards, so as to be- come acquainted with their diet. Here Is the Wheatear's bill of fare : Locusts, first of all; next, many various kinds of Beetles, such as Weevils, Opatra, Chrysomelae, or Golden- apple-beetles, Cassldas, or Tortoise-beetles, and Harpall; in the third place. Spiders, luli,^ Woodllce and small Snails; lastly and * Alphonse Tousserel (1803-1885), author of a number of interesting and valuable works on ornitholog}'. — Translator's Note. 'Also knov.n as the Stone-chat, Fallow-chat, Whin- chat, Fallow-finch and White-tail, which last corresponds with the Cul-blanc of the Provenqal dialect. The French name for this Saxicola is the Motteux, or Clod- hopper,— Translator's Note. * VVormlike Millepedes. — Translator's Note. 360 The Locusts: their Function rarely, bramble-berries and the berries of the Cornelian cherry. As you see, there is a little of all kinds of small game, just as it comes. The insect- eater does not turn his attention to berries except in the last resort, at seasons of dearth. Out of forty-eight cases mentioned in my notes, vegetable food appears only three times, in trifling proportions. The predomi- nant item, both as regards frequency and quantity, is the Locust, the smaller specimens being chosen, in order not to tax the bird's swallowing-powers. Even so with the other little birds of pass- age which, when autumn comes, call a halt in Provence and prepare for the great pil- grimage by accumulating on their rumps a travelling-allowance of fat. All of them feast on the Locust, that rich fare; all, in the waste lands and fallows, gather as best they can the hopping tit-bit, that source of vigour for flying. Locusts are the manna of little birds on their autumnal journey. Nor does man himself scorn them. An Arab author quoted by General Daumas ^ in his book, Le Grand desert, tells us : ^General Eugene Daumas (1803-1871), the author of several works on AXgtr \di.— Translator's Note. 361 The Life of the Grasshopper " Grasshoppers ^ are of good noiirisliment for men and Camels. Their claws, wings and head are taken away and they are eaten fresh or dried, either roast or boiled and served with flesh, flour and herbs. " When .dried in the sun, they are ground to powder and mixed with milk or kneaded with flour; and they are then cooked with fat or with butter and salt. *' Camels eat them greedily and are given them dried or roast, heaped in a hollow be- tween two layers of charcoal. Thus also do the Nubians eat them. "When Miriam- prayed God that she might eat flesh unpolluted by blood, God sent her Grasshoppers. " When the wives of the Prophet were sent Grasshoppers as a gift, they placed some of these in baskets and sent them to other women. " Once, when the Caliph Omar was asked if it were lawful to eat Grasshoppers, he made answer: " ' Would that I had a basket of them to eat!' ^ More correctly the Locust, not to be confused with the true Grasshopper, v/ho carries a sabre. — Author's Note. ^ The Blessed Virgin Mary. — Author's Note. 362 The Locusts: their Function " Wherefore, from this testimony, it is very sure that, by the grace of God, Grass- hoppers were given to man for his nourish- ment." Without going so far as the Arab natural- ist, which would presuppose a power of digestion not bestowed on every man, I feel entitled to say that the Locust is a gift of God to a multitude of birds, as witness the long array of gizzards which I consulted. Many others, notably the reptile, hold him in esteem. I have found him in the belly of the Rassado, that terror of the small girls of Provence, I mean the Eyed Lizard, who loves rocky shelters turned into a furnace by a torrid sun. And I have often caught the little Grey Lizard of the walls in the act of carrying off, in his tapering snout, the spolia opima of some long-awaited Acridian. Even fish revel in him, when good fortune brings him to them. The Locust's leap has no definite goal. A projectile discharged blindly, the Insect comes down wherever the unpremeditated release of its springs shoots it. If the place where It falls happen to be the water, a fish Is there at once to gobble up the dripping victim. It is sometimes a 363 The Life of the Grasshopper fatal dainty, for anglers use the Locust when they wish to bait their hook with a particu- larly attractive morsel. Without expatiating further on the devourers of this small game, I can clearly see the great usefulness of the Acridian who by successive leaps transmits to man, that most wasteful of eaters, the lean grass now converted into exquisite fare. Gladly there- fore would I say, with the Arab writer : " Wherefore, from this testimony, It is very sure that, by the grace of God, Grass- hoppers were given to man for his nourish- ment." One thing alone makes me hesitate : the direct consumption of the Locust. As re- gards Indirect consumption, under the form of Partridge, young Turkey and others, none will think of denying him his praises. Is direct consumption then so unpleasant? That was not the opinion of Omar,^ the mighty caliph, the destroyer of the library of Alexandria. His stomach was as rude as his Intellect; and, by his own account, he * Omar, the second caliph and the first to assume the title of Commander of the Faithful, reigned from 634 to his death in 644. The Alexandrian library was burnt in 640. — Translator's Note. 364 The Locusts: their Function would have relished a basket of Grass- hoppers. Long before him, others were content to eat them, though in this case it was a wise frugality. Clad in his Camel's-hair garment, St. John the Baptist, the bringer of good tidings and the great stirrer of the populace in the days of Herod, lived in the desert on Grasshoppers and wild honey : '' And his meat was locusts and wild honey," says the Gospel according to St. Matthew. Wild honey I know, if only from the pots of the Chalicodoma.^ It is a very agreeable food. There remains the Grasshopper of the desert, otherwise the Locust. In my youth, like every small boy, I appreciated a Grasshopper's leg, which I used to eat raw. It is not without flavour. To-day let us rise a peg higher and try the fare of Omar and St. John the Baptist. I capture some fat Locusts and have them copked in a very rough and ready fashion, fried with butter and salt, as the Arab author prescribes. We all of us, big and little, partake of the queer dish at dinner. * Cf. The Mason-bees: passim. — Translator's Note. 365 The Life of the Grasshopper We pronounce favourably upon the caliph's delicacy. It is far superior to the Cicadae extolled by Aristotle. It has a certain shrimpy flavour, a taste that reminds one of grilled Crab; and, were it not that the shell is very tough for such slight edible contents, I would go to the length of saying that it is good, without, however, feeling any desire for more. My curiosity as a naturalist has now twice allowed itself to be tempted by the dishes of antiquity: Cicadae first; Locusts next. Neither the one nor the other roused my enthusiasm. We must leave these things to the powerful jaws of the negroes and the huge appetite of which the famous caliph gave proof. The queaslness of our stomachs, however, In no way decreases the Locusts' merits. Those little browsers of the burnt grass play a great part In the workshop where our food is prepared. They swarm In vast legions which roam over the barren wastes, pecking here and there, turning what could not otherwise be used Into a foodstuff which Is passed on to a host of consumers, Including, first and foremost, the bird that often falls to man's share. 366 The Locusts: their Function Pricked relentlessly by the needs of the stomach, the world knows no more impera- tive duty than the acquisition of food. To secure a seat in the refectory, each animal expends its sum total of activity, industry, toil, trickery and strife; and the general ban- quet, which should be a joy, is to many a torment. Man is far from escaping the miseries of the struggle for food. On the contrary, only too often he tastes them in all their bitterness. Ingenious as he Is, will he succeed In free- ing himself from them? Science says yes. Chemistry promises, in the near future, a solution of the problem of subsistence. The sister science, physics, is preparing the way. Already it is contemplating how to get more and better work done by the sun, that great sluggard who thinks that he has done his duty by us when he sweetens our grapes and ripens our corn. It will bottle his heat, garner his rays. In order to control them and employ them where we think fit. With these supplies of energy, the hearths will blaze, the wheels will turn, the pestles pound, the graters grate, the rollers grind; and the work of agriculture, so wasteful at present, thwarted as it is by the inclemency Z^7 The Life of the Grasshopper of the seasons, will become factory-work, yielding economical and safe returns. Then chemistry will step in, with its legion of cunning reagents. It will turn every- thing into nutritious matter, in a highly con- centrated form, capable of being assimilated in its entirety and leaving hardly any foul residue. A loaf of bread will be a pill; a rumpsteak a drop of jelly. Of agricultural labour, the inferno of barbarian times, no- thing will remain but a memory, of Interest only to the historians. The last Sheep and the last Ox will figure, neatly stuffed, as curi- osities In our museums, together with the Mammoth dug up from the Siberian ice- fields. All that old lumber — herds and flocks, seeds, fruits and vegetables — is doomed to disappear som.e day. Progress demands it, we are told; and the chemist's retort, which, In its presumptuous fashion, recognizes no- thing as impossible, repeats the assertion. This golden age of foodstuffs leaves me very Incredulous. When it is a question of obtaining some new toxin, science displays alarming Ingenuity. Our laboratory collec- tions are veritable arsenals of poisons. When the object Is to invent a still in which 368 The Locusts: their Organ of Sound potatoes shall be made to yield torrents of alcohol capable of turning us into a nation of sots, the resources of industry know no limits. But to procure by artificial means a single mouthful of really nourishing matter is a very different business. Never has any such product simmered in our retorts. The fu- ture, beyond a doubt, will do no better. Or- ganized matter, the only true food, escapes the formulae of the laboratory. Its chemist is life. We shall do wxll therefore to preserve agriculture and our herds. Let us leave our nourishment to be prepared by the patient work of plants and animals, let us mistrust the brutal factory and keep our confidence for more delicate methods and, in particu- lar, for the Locust's stomach, which assists in the making of the Christmas Turkey. That stomach has culinary receipts which the chemist's retort will always envy without succeeding in imitating them. This picker-up of nutritive trifles, des- tined to support a crowd of paupers, pos- sesses musical powers wherewith to express his joys. Consider a Locust at rest, bliss- fully digesting his meal and enjoying the sunshine. With sharp strokes of the bow, 369 The Life of the Grasshopper three or four times repeated and spaced with pauses, he sings his ditty. He scrapes his sides with his great hind-legs, using now one, now the other, anon both at a time. The result is very poor, so slight indeed that I am obliged to have recourse to little Paul's ear in order to make sure that there is a sound at all. Such as it is, It resembles the creaking of the point of a needle pushed across a sheet of paper. There you have the whole song, so near akin to silence. There Is nothing more to be expected from so rudimentary an instrument. We have no- thing here similar to what the Grasshopper clan have shown us : no toothed bow, no vibrating membrane stretched Into a drum. Let us, for Instance, take a look at the Italian Locust {Caloptenus italicus, LiN. ), whose apparatus of sound is repeated in the other stridulating Acrldians. His hinder thighs are keel-shaped above and below. Each surface, moreover, has two powerful longitudinal nervures. Between these main parts there Is, In either case, a graduated row of smaller, chevron-shaped nervures; and the whole thing Is as prominent and as plainly marked on this outer side as on the inner one. And what surprises me even 370 The Locusts: their Organ of Sound more than this similarity between the two surfaces is that all these nervures are smooth. Lastly, the lower edge of the wing-cases, the edge rubbed by the thighs which serve as a bow, also has nothing particular about it. We see, as Indeed we do all over the wing- cases, nervures that are powerful but de- void of any rasping roughness or the least dentlculation. What can this artless attempt at a musical instrument produce ? Just as much as a dry membrane will emit when you rub It. And for the sake of this trifle the Insect lifts and lowers Its thighs. In sharp jerks, and Is satis- fied with the result. It rubs Its sides very much as we rub our hands together in sign of contentment, with no intention of making a sound. That Is Its own particular way of expressing its joy In life. Examine it when the sky Is partly ob- scured and the sun shines Intermittently. There comes a rift In the clouds. Forthwith the thighs begin to scrape, increasing their activity as the sun grows hotter. The strains are very brief, but they are renewed so long as the sunshine continues. The sky becomes overcast. Then and there the song ceases, to be resumed with the next gleam of sun- 371 The Life of the Grasshopper light, ahvays In brief spasms. There Is no mistaking It: here, In these fond lovers of the light, we have a mere expression of hap- piness. The Locust has his mioments of gaiety when his crop Is full and the sun benign. Not all the Acridians Indulge In this joy- ous rubbing. The Tryxalis ( TruxaUs jiasuta, Lin.), who sports a pair of Immensely elon- gated hind-legs, maintains a gloomy silence even under the most vigorous caresses of the sun. I have never seen him move his shanks like a bow; he seems unable to use them — so long are they — for anything but hopping. Dumb likewise, apparently as a conse- quence of the excessive length of his hind- legs, the big Grey Locust {Pachytilus cinerescens, Fabr.) has a peculiar way of diverting himself. The giant often visits me In the enclosure, even In the depth of winter. In calm weather, when the sun Is hot, I sur- prise him In the rosemaries, wuth his v/ings unfurled and fluttering rapidly for a quarter of an hour at a time, as though for flight. His twirling Is so gentle, In spite of Its ex- treme speed, as to create hardly a percepti- ble rustle. Others still are much less well-endowed. Z72 The Locusts: their Organ of Sound One such is the Pedestrian Locust (Pezo- tettix pedes tris, LiN. ), the companion of the Alpine Analota on the ridges of the Ven- toux. This foot-passenger stroUing amid the paronychias {P. serpyllifola) which he spread in silvery expanses over the Alpine region; this short-jacketed hopper, the guest of the androsaces {A. villosa), whose tiny flowers, white as the neighbouring snows, smile from out of their rosy eyes, has the same fresh colouring as the plants around him. The sunlight, less veiled in mists in the loftier regions, has made him a costume combining beauty and simplicity: a pale- brown satin back; a yellow abdomen; big thighs coral-red below; hind-legs a glori- ous azure-blue, v/Ith an Ivory anklet in front. But, being Incapable of going beyond the larval form, this dandy remains short- coated. He has for wing-cases two wrinkled slips, distant one from the other and hardly cover- ing the first segment of the abdomen, and for wings two stumps that are even more abbreviated. All this hardly covers his na- kedness down to the waist. Any one seeing him for the first time takes him for a larva and is wrong. It Is Indeed the adult Insect, 373 The Life of the Grasshopper ripe for mating; and the insect will remain in this undress to the end. Is it necessary to add that, with this skimpy jacket, stridulation is impossible? The big hind-thighs are there, it is true ; but what is lacking, for them to rub upon, is the grating surface, the edge of the wing-cases. Whereas the other Locusts are not to be de- scribed as noisy, this one is absolutely dumb. In vain have the most delicate ears around me listened with might and main : there has never been the least sound during the three months' home breeding. This si- lent one must have other means of ex- pressing his joys and summoning his partner to the wedding. What are they? I do not know. Nor do I know why the insect deprives itself of wings and remains a plodding way- farer, when its near kinsmen, on the same Alpine swards, are excellently equipped for flight. It possesses the germs of wing and wing-case, gifts which the egg gives to the larva; and it does not think of using these germs by developing them. It persists in hopping, with no further ambition; it is satis- fied to go on foot, to remain a Pedestrian Locust, as the nomenclators call It, when It 374 The Locusts: their Organ of Sound might, one would think, acquire wings, that higher mechanism of locomotion. Rapid flitting from crest to crest, over the valleys deep in snow; easy flight from a shorn pasture to one not yet exploited : can these be negligible advantages to the Pedes- trian Locust? Obviously not. The other Acrldians and in particular his fellow- dwellers on the mountain-tops possess wings and are all the better for them. What is his reason for not doing as they do? It would be very profitable to extract from their sheaths the sails v/hlch he keeps packed away In useless stumps; and he does not do it. Why? ** Arrested development," says some one. Very well. Life Is arrested half-way through Its work; the Insect does not attain the ultimate form of which It bears the em- blem. For all its scientific turn of phrase, the reply Is not really a reply at all. The question returns under another guise : what causes that arrested development? The larva Is born with the hope of flying at maturity. As a pledge of that fair future, it carries on Its back four sheaths in which the precious germs He slumbering. Every- thing Is arranged according to the rules of 375 The Life of the Grasshopper normal evolution. Thereupon, suddenly, the organism does not fulfil its promises; it is false to its engagements; it leaves the adult insect without sails, leaves it with only- useless rags. Are we to lay this nudity to the charge of the harsh conditions of Alpine life? Not at all, for the other hoppers, living on the same grassy slopes, manage very well to achieve the wings foretold by the larva's rudiments. Men tell us that, from one attempt to an- other, from progress to progress, under the stimulus of necessity, animals end by ac- quiring this or that organ. No other crea- tive intervention is accepted than that of need. This, for instance, is the way in which the Locusts went to work, in particu- lar those vv^hom I see fluttering over the ridges of the Ventoux. From their nig- gardly larval flaps they are supposed to have extracted wings and wing-cases, by virtue of secret and mysterious labours rendered fruitful by the centuries. Very well, O my illustrious masters ! And now tell me, if you please, what rep.sons per- suaded the Pedestrian Locust not to go be- yond his rude outline of a flying-apparatus. 376 The Locusts: their Organ of Sound He also, surely, must have felt the prick of necessity for ages and ages; during his la- borious tumbles amid the broken stones, he must have felt the advantage that it would be for him to be relieved of his weight by means of wing-power; and all the endeavours of his organism, striving to achieve a better lot, have not yet succeeded in spreading bladewise his incipient wings. If we accept your theories, under the same conditions of urgent necessity, diet, climate and habits, some are successful and manage to fly, others fail and remain clumsy pedes- trians. Short of resting satisfied with words and passing off chalk for cheese, I abandon the explanations offered. Sheer ignorance is far preferable, for it prejudges nothing. But let us leave this backward one who is a stage behind his kinsmen, no one knows why. Anatomy has its throwbacks, its halts, its sudden leaps, all of which defy our curi- osity. In the presence of the unfathomable problem of origins, the best thing is to bow in all humihty and pass on. zn CHAPTER XVIII THE LOCUSTS: THEIR EGGS \T ^HAT can our Locusts do ? Not much ^ ^ In the way of manufactures. Their business in the world is that of alchemists who in their gourdlike stomach elaborate and refine material destined for higher ob- jects. As I sit by my fireside, in the evening hours of meditation, scribbling these notes upon the part which Locusts play in life, I am not prepared to say that they have not contributed from time to time to the awaken- ing of thought, that magic mirror of things. They are on the earth to thrive as best they can and to multiply, the latter being the highest law of animals charged with the manufacture of foodstuffs. From the former point of view, If we ex- cept the all-devouring tribes which at times imperil the very existence of Africa, the Lo- custs hardly attract our attention. They are poor trenchermen; and I can surfeit a whole 378 The Locusts: their Eggs barrack-room In my cages with a leaf of let- tuce. As for the way in which they multiply, that is another matter and one well worth a moment's attention. At the same time we must not look for the nuptial eccentricities of the Grasshoppers. Despite close similarity of structure, we are here in a new world as regards habits and character. In the peaceful Locust clan, all that has to do with pairing is correct, free from impropriety and conducted In accord- ance with the customary rites of the ento- mological world. Any one keeping It under observation at the time of the procreatlve frenzy will realize that the Locust came later than the Grasshopper, after the primi- tive Orthopteron had sown his monstrous wild oats. There is nothing striking to be said therefore on this always delicate sub- ject; and I am very glad of It. Let us pass on and come to the eggs. At the end of August, a little before noon- day, let us keep a close watch on the Italian Locust (Caloptenus italicus, LiN.), the bold- est hopper of my neighbourhood. He Is a sturdy fellow, very free with his kicks; and he is clad In short wing-cases that hardly reach the tip of his abdomen. His costume 379 The Life of the Grasshopper is usually russet, with brown patches. A few more elegant ones edge the corselet with a whitish hem which is prolonged over the head and wing-cases. The wings are colourless except at the base, where they are pink; the hinder shins are claret-coloured. The mother selects a suitable spot for her eggs on the side where the sun is hottest and always at the edge of the cage, whose wire- work supplies her with a support in case of need. Slowly and laboriously she drives her clumsy drill perpendicularly into the sand, this drill being her abdomen, which disap- pears entirely. In the absence of proper boring-tools, the descent underground is painful and hesitating, but is at last accom- plished thanks to perseverance, that powerful lever of the weak. The mother is now installed, half-buried in the soil. She gives slight starts, which follow one another at regular intervals and seem to correspond with the efforts of the oviduct as it expels the eggs. The neck gives throbs that lift and lower the head with slight jerks. Apart from these pulsa- tions of the head, the body, in Its only visible half, the fore-part, is absolutely stationary, so intense Is the creature's absorption in her 38a The Locusts: their Eggs laying. It is not unusual for a male, by com- parison a dwarf, to come near and for a long time to gaze curiously at the travailing mother. Sometimes also a few females stand around, with their big faces turned to- wards their friend in labour. They seem to take an interest in what is happening, per- haps saying to themselves that it will be their turn soon. After some forty minutes of immobility, the mother suddenly releases herself and bounds far aw^ay. She gives not a look at the eggs nor a touch of the broom to conceal the aperture of the well. The hole closes of its own accord, as best it can, by the natural falllng-in of the sand. It is an extremely summary performance, marked by an utter absence of maternal solicitude. The Locust mother is not a model of affection. Others do not forsake their eggs so reck- lessly. I can name the ordinary Locust with the blue wings striped with black {CEdipoda ccerulescens, LiN. ) ; also Pachytyliis nigro- fasciatus, De Geer, whose cognomen lacks point, for it ought to suggest either the malachite-green patches of the costume or the white cross of the corselet. Both, when laying their eggs, adopt the 381 The Life of the Grasshopper same attitude as the Itahan Locust. The abdomen is driven perpendicularly into the soil; the rest of the body partly disappears under the sliding sand. We again see a long period of Immobility, exceeding half an hour, together with little jerks of the head, a sign of the underground efforts. The two mothers at last release them- selves. With their hind-legs, lifted on high, they sweep a little sand over the orifice of the pit and press it down by stamping rap- idly. It is a pretty sight to watch the pre- cipitous action of their slender legs, blue or pink, giving alternate kicks to the opening which is waiting to be plugged. In this manner, with a lively trampling, the entrance to the house is closed and hidden away. The hole in which the eggs were laid disappears from sight, so well obliterated that no evil- intentloned creature could hope to discover It by means of vision alone. Nor is this all. The driving-power of the two rammers is the hinder thighs, which, in rising and falling, scrape lightly against the edge of the wing-cases. This bow-play pro- duces a faint stridulatlon, similar to that with which the insect placidly lulls itself to sleep in the sun. 382 The Locusts: their Eggs The Hen salutes the egg which she has just laid with a song of gladness; she an- nounces her maternal joys, to the whole neighbourhood. Even so does the Locust do in many cases. With her thin scraper, she celebrates the advent of her family. She says: '' Non omnis moriar; I have buried under- ground the treasure of the future; I have entrusted to the incubation of the great hatcher a keg of germs which will take my place." Everything on the site of the nest is put right in one brief spell of work. The mother then leaves the spot, refreshes herself after her exertions with a few mouthfuls of green stuff and prepares to begin again. The largest of the Acridians in our part of the country, the Grey Locust {P achy ty his cinerescens, Fabr. ), rivals the African Lo- custs in size, without possessing their calami- tous habits. He is peace-loving and tem- perate and above reproach where the fruits of the earth are concerned. From him we obtain a little information which is easily verified by observing the insect in captivity. The eggs are laid about the end of April, a few days after the pairing, which lasts 383 The Life of the Grasshopper some little while. The female is armed at the tip of the abdomen — as, in varying de- grees, are the other Locust mothers — with four short excavators, arranged in pairs and shaped like a hooked finger-nail. In the upper pair, which are larger, these hooks are turned upwards; in the lower and smaller pair, they are turned downwards. They form a sort of claw and are hard and black at the point; also they are scooped out slightly, like a spoon, on their concave sur- face. These are the pick-axes, the trepans, the boring-tools. The mother bends her long abdomen per- pendicularly to the line of the body. With her four trepans she bites into the soil, lift- ing the dry earth a little ; then, with a very slow movement, she pushes down her ab- domen, making no apparent effort, display- ing no excitement that would reveal the dif- ficulty of the task. The insect Is motionless and contemplative. The boring-Implement could not work more quietly if it were sinking into soft mould. It might all be happening in butter; and yet what the bore traverses Is caked, unyielding earth. It would be Interesting, If It were only pos- 384 The Locusts: their Eggs sible, to see the perforating-tool, the four gimlets, at work. Unfortunately, things happen in the mysteries of the earth. No rubbish rises to the surface; nothing de- notes the underground labour. Little by little the abdomen sinks softly in, as our finger would sink into a lump of soft clay. The four trepans must open the passage, crumbling the earth into dust which is thrust back sideways by the abdomen and packed as with a gardener's dibble. The best site for laying the eggs is not always found at the first endeavour. I have seen the mother drive her abdomen right in and make five wells one after the other be- fore finding a suitable place. The pits recognized as defective are abandoned as soon as bored. They are vertical, cylindrical holes, of the diameter of a thick lead-pencil and astonishingly neat. No wimble would produce cleaner work. Their length is that of the insect's abdomen, distended as far as the extension of the segments allows. At the sixth attempt, the spot is recognized as propitious. The laying thereupon takes place, but nothing outside betrays the fact, so motionless does the mother seem, with her abdomen immersed up to the hilt, which 385 The Life of the Grasshopper causes the long wings lying on the ground to rumple and open out. The operation lasts for a good hour. At last the abdomen rises, little by little. It is now near the surface, in a favourable position for observation. The valves are in continual movement, whipping a mucus which sets in milk-white foam. It is very similar to the work done by the Mantis when enveloping her eggs in froth. The foamy matter forms a nipple at the entrance to the well, a knob which stands well up and attracts the eye by the white- ness of its colour against the grey back- ground of the soil. It is soft and sticky, but hardens pretty soon. When this closing button is finished, the mother moves away and troubles no more about her eggs, of which she lays a fresh batch elsewhere after a few days have intervened. At other times, the terminal foamy paste does not reach the surface; it stops some way down and, before long, is covered with the sand that slips from the margin. There is then nothing outside to mark the place where the eggs were laid. Even when they concealed the mouth of the well under a layer of swept sand, my 386 The Locusts: their Eggs various captives, large and small, were too assiduously watched by me to foil my curi- osity. I know in every case the exact spot where the barrel of eggs lies. The time has come to inspect it. The thing is easily discovered, an inch or an inch and a half down, with the point of a knife. Its shape varies a good deal in the different species, but the fundamental struc- ture remains the same. It is always a sheath made of solidified foam, a similar foam to that of the nests of the Praying Mantis. Grains of sand stuck together give it a rough outer covering. The mother has not actually made this coarse cover, which constitutes a defensive wall. The mineral wrapper results from the simple infiltration of the product, at first semifluid and viscous, that accompanies the emission of the eggs. The wall of the pocket absorbs it and, swiftly hardening, be- comes a cemented scabbard, without the agency of any special labour on the insect's part. Inside, there is no foreign matter, nothing but foam and eggs. The latter occupy only the lower portion, where they are immersed in a frothy matrix and packed one on top 387 The Life of the Grasshopper of the other, slantwise. The upper portion, which is larger in some cases than in others, consists solely of soft, yielding foam. Be- cause of the part which it plays when the young larvs come into existence, I shall call it the ascending-shaft. A final point worthy of observation is that all the sheaths are planted more or less vertically in the soil and end at the top almost level with the ground. We will now describe specifically the lay- ings which we find in the cages. That of Pachytylus cinerescens is a cylinder six centi- metres long and eight millimetres wide.^ The upper end, v/hen it emerges above the ground, swells into a nipple. All the rest is of uniform thickness. The yellow-grey eggs are fusiform. Immersed in the froth and arranged slantwise, they occupy only about a sixth part of the total length. The rest of the structure is a fine, white, very powdery foam, soiled on the outside by grains of earth. The eggs are not many in number, about thirty; but the mother lays several batches. That of P. nigrofasciatus is shaped like a slightly curved cylinder, rounded off at the ^ 2.34 by .312 inches. — Translator's Note. 388 The Locusts: their Eggs lower end and cut square at the upper end. Its dimensions are an inch to an inch and a half in length by a fifth of an inch in width. The eggs, about twenty in number, are orange-red, adorned with a pretty pattern of tiny spots. The frothy matrix in which they are contained is small in quantity; but above them there is a long column of very fine, transparent and porous foam. The Blue-winged Locust {CEdipoda cosru- lescens) arranges her eggs in a sort of fat inverted comma. The lower portion con- tains the eggs in its gourd-shaped pocket. They also are few in number, some thirty at most, of a fairly bright orange-red, but unspotted. This receptable is crowned with a curved, conical cap of foam. The lover of the mountain-tops, the Pedes- trian Locust, adopts the same method as the Blue-winged Locust, the denizen of the plains. Her sheath too is shaped like a comma with the point turned upwards. The eggs, numbering about two dozen, are dark- russet and are strikingly ornamented with a delicate lacework of inwrought spots. You are quite surprised when you pass the mag- nifying-glass over this unexpected elegance. Beauty leaves its impress everywhere, even 389 The Life of the Grasshopper in the humble covering of an unsightly Acridian incapable of flight. The Italian Locust begins by enclosing her eggs in a keg and then, when on the point of sealing her receptacle, thinks better of it: something essential, the ascending-shaft, is lacking. At the upper end, at the point where It seems as if the barrel ought to finish and close, a sudden compression changes the course of the work, which Is prolonged by the regulation foamy appendage. In this way, two storeys are obtained, clearly de- fined on the outside by a deep groove. The lower, which Is oval in shape, contains the packet of eggs; the upper, tapering into the tail of a comma, consists of nothing but foam. The two communicate by an opening that remains more or less free. The Locust's art Is not confined to these specimens of architecture. She knows how to construct other strong-boxes for her eggs; she can protect them with all kinds of edifices, some simple, others more Ingenious, but all worthy of our attention. Those with which we are familiar are very few compared with those of which we are Ignorant. No matter : what the cages reveal to us is sufficient to enlighten us as to the general form. It re- 390 The Locusts: their Eggs mains for us to learn how the building — an egg-warehouse below, a foamy turret above — is constructed. Direct observation is Impracticable here. If w^e took it into our heads to dig and to uncover the abdomen at work, the mother, worried by our Importunity, would leap away without telling us anything. Fortunately, one Locust, the strangest of my district, re- veals the secret to us. I speak of the Tryxalis, the largest member of the family, after the Grey Locust. Though inferior to the last-named in size, how far she exceeds her In slenderness of figure and, above all, in originality of shape ! On our sun-scorched swards, none has a leaping-apparatus to compare with hers. What hind-legs, what extravagant thighs, what shanks! They are longer than the creature's whole body. The result obtained hardly corresponds with this extraordinary length of limb. The insect shuffles awkwardly along the edges of the vines, on the sand sparsely covered with grass; It seems embarrassed by Its shanks, which are slow to work. With this equip- ment, weakened by Its excessive length, the leap is awkward, describing but a short 391 The Life of the Grasshopper parabola. The flight alone, once taken, is of a certain range, thanks to an excellent pair of wings. And then what a strange head! It is an elongated cone, a sugar-loaf, whose point, turned up in the air, has earned for the insect the quaint epithet of nasuta, long- nosed. At the top of this cranial promon- tory are two large, gleaming, oval eyes and two antennse, flat and pointed, like dagger- blades. These rapiers are organs of in- formation. The Tryxalis lowers them, with a sudden swoop, to explore with their points the object in which she is interested, the bit which she intends to nibble. To this abnormal shape we must add an- other characteristic that makes this long- shanks an exception among Acridlans. The ordinary Locusts, a peaceful tribe, live among themselves without strife, even when driven by hunger. The Tryxalis, on the other hand, is somewhat addicted to the can- nibalism of the Grasshoppers. In my cages, in the midst of plenty, she varies her diet and passes easily from salad to game. When tired of green stuff, she does not scruple to exercise her jaws on her weaker companions. This is the creature capable of giving us 392 The Locusts: their Eggs information about methods of laying. In my cages, as the result of an aberration due no doubt to the boredom of captivity, it has never laid its eggs in the ground. I have always seen it operating in the open air and even perched on high/ In the early days of October, the insect clings to the trelliswork of the cage and very slowly discharges its batch of eggs, which we see gushing forth in a fine, foamy stream, soon stiffening into a thick cylindrical cord, knotty and queerly curved. It takes nearly an hour to complete the emission. Then the thing falls to the ground, no matter where, unheeded by the mother, who never troubles about it again. The shapeless object, which varies greatly in different layings, is at first straw-coloured, then darkens and turns rusty-brown on the morrow. The fore-part, which is the first ejected, usually consists only of foam; the hinder part alone is fertile and contains the eggs, burled in a frothy matrix. They are amber-yellow, about a score in number and shaped like blunt spindles, eight to nine millimetres in length.^ * The big Grey Locust is sometimes subject to the same aberration. — Author's Note. ' .312 to .351 inch. — Translator's Note. 393 The Life of the Grasshopper The sterile end, which is at least as big as the other, tells us that the apparatus which produces the foam is in operation before the oviduct and afterwards goes on while the latter is working. By what mechanism does the Tryxalis froth up her viscous product into a porous column first and a mattress for the eggs after- wards? She must certainly know the method of the Praying Mantis, who, with the aid of spoon-shaped valves, whips and beats her glair and converts it into an omelette soiif- fiee; but in the Acridian's case the frothing Is done within and there Is nothing outside to betray Its existence. The glue is foamy from the moment of Its appearing In the open air. In the Mantis' building, that complex work of art, It Is not a case of any special talent, which the mother can exercise at will. The wonderful egg-casket comes from the ordi- nary action of the mechanism, is merely the outcome of the organization. A fortiori, the Tryxalis, In discharging her clumsy sausage, Is purely a machine. The thing happens of itself. The same applies to the Locusts. They have no industry of their own specially de- 394 The Locusts: their Eggs vised for laying eggs in strata in a keg of froth and extending this keg into an ascend- ing-shaft. The mother, with her abdomen plunged into the sand, expels at the same time eggs and foamy glair. The whole be- comes coordinated of its own accord simply by the mechanism of the organs : on the out- side, the frothy material, which coagulates and becomes encrusted with a bulwark of earth; in the centre and at the bottom, the eggs arranged in regular strata ; at the upper end, a column of yielding foam. The Tryxalis and the Grey Locust are early hatchers. The latter's family are al- ready hopping on the yellow patches of grass in August; before October is out, we are fre- quently coming across young larvae with pointed skulls. But in most of the other Acridians the ovigerous sheaths last through the winter and do not open until the fine weather returns. They are buried at no great depth in a soil which is at first loose and dusty and which would not be likely to interfere with the emergence of the young larvse if it remained as it is; but the winter rains cake it together and turn it into a hard ceiling. Suppose that the hatching takes place only a couple of inches down: how is 395 The Life of the Grasshopper this crust to be broken, how is the larva to come up from below? The mother's uncon- scious art has provided for that. The Locust at his birth finds above him, not rough sand and hardened earth, but a perpendicular tunnel whose solid walls keep all difficulties at a distance, a road protected by a little easily-penetrated foam, an ascend- ing-shaft, in short, which brings the new-born larva quite close to the surface. Here a finger's-breadth of serious obstacle remains to be overcome. The greater part of the emergence there- fore Is accomplished without effort, thanks to the terminal appendage of the egg-barrel. If, in my desire to follow the underground work of the exodus, I experiment In glass tubes, almost all the new-born larvae die, ex- hausted with fatigue, under an Inch of earth, when I do away with the liberating append- age to the shells. They duly come to light if I leave the nest in Its Integral condition, with the ascending-shaft pointing upwards. Though a mechanical product of the organ- ism, created without any effort of the crea- ture's intelligence, the Locust's edifice, we must confess, is singularly well thought out. 396 The Locusts: their Eggs Having come quite close to the surface ^\ith the aid of his ascending-shaft, what does the young Locust do to complete his deliver- ance? He has still to pass through a layer of earth about a finger's-breadth in thick- ness ; and that is very hard work for budding flesh. If we keep the egg-cases in glass tubes during the favourable period, the end of spring, we shall receive a reply to our quest- ion, provided that we have the requisite pa- tience. The Blue-winged Locusts lend them- selves best to my investigations. I find some of them busied with the work of liberation at the end of June. The little Locust, on leaving his shell, is a whitish colour, clouded with light red. His progress is made by wormlike move- ments; and, so that It may be impeded as little as possible, he is hatched in the condi- tion of a mummy, that is to say, clad, like the young Grasshoppers, in a temporary jacket, which keeps his antennae, palpi and legs closely fixed to his breast and belly. The head Itself Is very much bent. The large hind-thighs are arranged side by side with the folded shanks, shapeless as yet, short and as it were crooked. On the way, the 397 The Life of the Grasshopper legs are slightly released; the hind-legs are straightened out and afford a fulcrum for the sapping-work. The boring-tool, a repetition of the Grasshoppers', is at the neck. There is here a tumour that swells, subsides, throbs and strikes the obstacle with pistonlike regularity. A tiny and most tender cervical bladder en- gages in a struggle with quartz. At the sight of this capsule of glair striving to over- come the hardness of the mineral, I am seized with pity. I come to the unhappy creature's assistance by slightly damping the layer to be passed through. Despite my intervention, the task is so arduous that, In an hour, I see the indefati- gable one make a progress of hardly a twenty-fifth of an inch. How you must la- bour, you poor little thing, how you must persevere with your throbbing head and writhing loins, before you can clear a pass- age for yourself through the thin layer which my kindly drop of water has softened for you ! The ineffectual efforts of the tiny mite tell us plainly that the emergence into the light of day Is an enormous undertaking. In which, but for the aid of the exit-tunnel, the 398 The Locusts: their Eggs mother's work, the greater number would succumb. It is true that the Grasshoppers, similarly equipped, find it even more difficult to make their way out of the earth. Their eggs are laid naked in the ground; no outward pass- age is prepared for them beforehand. We may assume, therefore, that the mortality must be very high among these improvident ones; legions are bound to perish at the time of the exodus. This is confirmed by the comparative scarcity of Grasshoppers and the extreme abundance of Locusts. And yet the number of eggs laid is about the same in both cases. The Locust does not, in fact, limit herself to a single casket containing a score of eggs : she puts into the ground two, three and more, which gives a total population ap- proaching that of the Decticus and other Grasshoppers. If, to the greater delight of the consumers of small game, she thrives so well, whereas the Grasshopper, who is quite as fertile but less ingenious, dwindles, does she not owe it to that superb invention, her exit-turret? One last word upon the tiny insect which, for days on end, fights away with its cervical 399 The Life of the Grasshopper rammer. It Is outside at last and rests for a moment, to recover from all that fatigue. Then, suddenly, under the thrust of the throbbing blister, the temporary jacket splits. The rags are pushed back by the hind-legs, which are the last to strip. The thing Is done : the creature is free, pale In colouring as yet, but possessing the final larval form. Then and there, the hind-legs, hitherto stretched In a straight line, adopt the regula- tion position; the legs fold under the great thighs; and the spring Is ready to work. It works. Little Locust makes his entrance into the world and hops for the first time. I offer him a bit of lettuce the size of my finger- nail. He refuses. Before taking nourish- ment, he must first mature and develop for a while In the sun. JOG CHAPTER XIX THE LOCUSTS: THE LAST MOULT I HAVE just beheld a stirring sight: the last moult of a Locust, the extraction of the adult from his larval wrapper. It Is magnificent. The object of my enthusiasm is the Grey Locust, the giant among our Acrldlans, who is common on the vines at vintage-time, In September. On account of his size — he Is as long as my finger — he is a better subject for observation than any other of his tribe. The fat, ungraceful larva, a rough draft of the perfect insect, is usually pale-green; but some also are bluish-green, dirty-yellow, red-brown or even ashen-grey, like the grey of the adult. The corselet is strongly keeled and notched, with a sprinkling of fine white worm-holes. The hind-legs, powerful as those of mature age, have a great haunch striped with red and a long shank shaped like a two-edged saw. 401 The Life of the Grasshopper The wing-cases, which in a few days will project well beyond the tip of the abdomen, are In their present state two skimpy, tri- angular pinions, touching back to back along their upper edges and continuing the keel of the corselet. Their free ends stand up like a pointed gable. These two coat-tails, of which the material seems to have been clipped short with ridiculous meanness, just cover the creature's nakedness at the small of the back. They shelter two lean strips, the germs of the wings, which are even more exiguous. In brief, the sumptuous, slender sails of the near future are at present sheer rags, of such meagre dimensions as to be grotesque. What will come out of these miserable envelopes? A marvel of stately elegance. Let us observe the proceedings In detail. Feeling itself ripe for transformation, the creature clutches the trelllswork of the cage with Its hinder and Intermediary legs. The fore-legs are folded and crossed over the breast and are not employed in supporting the Insect, which hangs In a reversed posi- tion, back downwards. The triangular pin- ions, the sheaths of the wing-cases, open their peaked roof and separate sideways; the two 402 The Locusts: the last Moult narrow strips, the germs of the wings, stand in the centre of the uncovered space and diverge slightly. The position for the moult has now been taken with the necessary stability. The first thing to be done is to burst the old tunic. Behind the corselet, under the pointed roof of the prothorax, pulsations are produced by alternate inflation and de- flation. A similar operation Is performed In front of the neck and probably also under the entire covering of the shell that is to be split. The delicacy of the membranes at the joints enables us to perceive what Is going on at these bare points, but the harness of the corselet hides it from us in the central portion. It is there that the Insect's reserves of blood flow in waves. The rising tide ex- presses itself in blows of an hydraulic bat- tering-ram. Distended by this rush of hu- mours, by this injection wherein the organism concentrates its energies, the skin at last splits along a line of least resistance pre- pared by life's subtle previsions. The fissure yawns all along the corselet, opening pre- cisely over the keel, as though the two sym- metrical halves had been soldered. Un- 403 The Life of the Grasshopper breakable any elsewhere, the wrapper yields at this median point which is kept weaker than the rest. The split is continued some little way back and runs between the fasten- ings of the wings; it goes up the head as far as the base of the antennae, where it sends a short ramification to the right and left. Through this break the back is seen, quite soft, pale, hardly tinged with grey. Slowly it swells into a larger and larger hunch. At last it is wholly released. The head follows, extracted from its mask, which remains in its place, intact in the smallest particular, but looking strange with its great glassy eyes that do not see. The sheaths of the an- tennae, with not a wrinkle, with nothing out of order and with their normal position un- changed, hang over this dead face, which is now translucent. Therefore, in emerging from their narrow sheaths, which enclosed them with such abso- lute precision, the antennary threads encoun- tered no resistance capable of turning their scabbards inside out, or disturbing their shape, or even wrinkling them. Without in- juring the twisted containers, the contents, equal in size and themselves twisted, have managed to slip out as easily as a smooth, 404 The Locusts: the last Moult straight object would do, If sliding in a loose sheath. The extraction-mechanism will be still more remarkable in the case of the hind-legs. Meanwhile it is the turn of the fore-legs and then of the intermediary legs to shed armlets and gauntlets, always without the least rent, however small, without a crease of rumpled material, without a trace of any change in the natural position. The insect Is now fixed to the top of the cage only by the claws of the long hind-legs. It hangs perpendicularly, head downwards, swinging like a pendulum, if I touch the wire-gauze. Four tiny hooks are what it hangs by. If they gave way, if they became unfastened, the insect would be lost, for it is incapable of unfurling its enormous wings anywhere ex- cept in space. But they will hold: life, be- fore withdrawing from them, left them stiff and solid, so as to be able firmly to support the struggles that are to follow. The wing-cases and wings now emerge. These are four narrow strips, faintly grooved and looking like bits of paper rib- bon. At this stage, they are scarcely a quarter of their final length. So limp are they that they bend under their own weight 405 The Life of the Grasshopper and sprawl along the Insect's sides In the opposite direction to the normal. Their free end, which should be turned backwards, now points towards the head of the Locust, who is hanging upside down. Imagine four blades of thick grass, bent and battered by a rainstorm, and you will have a fair pic- ture of the pitiable bunch formed by the future organs of flight. It must be no light task to bring things to the requisite stage of perfection. The deeper-seated changes are already well- started, solidifying liquid mucilages, bringing order out of chaos; but so far nothing out- side betrays what Is happening In that mys- terious laboratory where everything seems lifeless. Meanwhile, the hind-legs become released. The great thighs appear in view, tinted on their inner surface with a pale pink, which will soon turn Into a streak of bright crimson. The emergence is easy, the bulky haunch clearing the way for the tapering knuckle. It Is different with the shank. This, in the adult insect, bristles throughout its length with a double row of hard, pointed spikes. Moreover, the lower extremity ends in four large spurs. It Is a genuine saw, but 406 The Locusts: the last Moult with two parallel sets of teeth and so power- ful that, if we dismiss the size from our minds, it might be compared with the rough saw wielded by a quarryman. The larva's shin is similarly constructed, so that the object to be extracted is con- tained In a sheath as awkwardly shaped as itself. Each spur Is enclosed in a similar spur, each tooth fits into the hollow of a similar tooth; and the moulding Is so exact that we should obtain no more intimate con- tact if, instead of the envelope waiting to be shed, we coated the limb with a layer of varnish distributed uniformly with a fine brush. Nevertheless the sawlike tibia slips out of its long, narrow case without catching in it at any point whatever. If I had not seen this happen over and over again, I could never have believed it: the discarded legging Is quite intact all the way down. Neither the terminal spurs nor the two rows of spikes have caught In the delicate mould. The saw has respected the dainty scabbard which a puff of my breath Is enough to tear; the formidable rake has slipped through without leaving the least scratch behind It. I was far from expecting such a result as 407 The Life of the Grasshopper this. Because of the spiked armour, I im- agined that the leg would strip in scales which came loose of themselves or yielded to rubbing, like dead cuticle. How greatly did the reality exceed my expectations ! From the spurs and spikes of the infinitely thin matrix there emerge spurs and spikes that make the leg capable of cutting soft wood. This is done without violence or the least inconvenience; and the discarded gar- ment remains where It is, hanging by the claws to the top of the cage, uncreased and untorn. The magnifylng-glass shows not a trace of rough usage. As the thing was before the excoriation, so it remains after- wards. The legging of dead skin continues, down to the pettiest details, an exact replica of the live leg. If any one suggested that we should ex- tract a saw from some sort of goldbeater's- skin sheath which had been exactly moulded on the steel and that we should perform the operation without producing the least tear, we should burst out laughing: the thing is so flagrantly impossible. Life makes light of these impossibilities; It has methods of realizing the absurd, in case of need. And the Locust's leg tells us so. 408 The Locusts: the last Moult If the saw of the shin were as hard as It Is once it leaves its sheath, it would abso- lutely refuse to come out without tearing to pieces the tight-fitting scabbard. The dif- ficulty therefore is evaded, for it is essential that the leggings, which form the only sus- pension-cords, should remain intact in order to furnish a firm support until the deliver- ance is completed. The leg in process of liberation is not a limb fit for walking; it has not the rigidlt^^ which It will presently possess. It is soft and highly flexible. In the portion which the progress of the moult exposes to view, I see it bending and curving as I wish, under the mere influence of Its own weight, when I lift the cage. It Is as supple as elastic cord. And yet consolidation follows very rapidly, for the proper stiffness will be ac- quired In a few minutes. Farther on, in the part hidden from me by the sheath, the leg is certainly softer and in a state of exquisite plasticity — I was al- most saying fluidity — which allows It to overcome diflicult passages almost as a liquid would flow. The teeth of the saw are there, but have none of their future sharpness. I am able 409 The Life of the Grasshopper to strip a leg partially with the point of a knife and to extract the spines from their horny mould. They are germs of spikes, flexible buds which bend under the slightest pressure and resume their upright position as soon as the pressure is removed. These spikes lie backwards when the leg is about to be drawn out; they stand up again and solidify while it emerges. I am witnessing not the mere stripping of gaiters from limbs completely enclosed, but rather a sort of birth and growth which disconcert us by their rapidity. Much in the same way, but with far less delicate precision, do the claws of the Cray- fish, at moulting-time, withdraw the soft flesh of their two fingers from the old stony sheath. The shanks are free at last. They are folded limply in the groove of the thigh, there to mature without moving. The ab- domen is next stripped. Its fine tunic wrin- kles, rumples and pushes back towards the extremity, which alone fcr some time longer remains clad in the moulting skin. Except at this point, the whole of the Locust is now bare. It is hanging perpendicularly, head down, 410 The Locusts: the last Moult supported by the claws of the now empty « leggings. Throughout this long and finikin I work, the four talons have never yielded, thanks to the delicacy and care with which the extraction has been conducted. The Insect, fixed by the stern to its cast skin, does not move. Its abdomen is im- mensely swollen, apparently distended by the reserve of organizable humours which the expansion of the wings and wing-cases will soon set in motion. The Locust is rest- ing; he is recovering from his exertions. Twenty minutes are spent in waiting. Then, by an effort of its back, the hanging insect raises itself and with its front tarsi grabs hold of the cast skin fastened above it. Never did acrobat, swinging by his feet from the bar of a trapeze, display greater strength of loin in lifting himself. When this feat is accomplished, what remains to be done is nothing. With the support which he has now gripped, the Locust climbs a little higher and reaches the wire gauze of the cage. This takes the place of the brush- wood which the free insect would utilize for the transformation. He fixes himself to It with his four front feet. Then the tip of the abdomen succeeds in releasing itself, 411 The Life of the Grasshopper whereupon, loosened with one last shake, the empty husk drops to the ground. The fact of its falling interests me, for I remember the stubborn persistency with which the Cicada's cast skin defies the winter winds without being detached from its sup- porting twig. The Locust's transfiguration is conducted in much the same way as the Cicada's. Then how is it that the Acridian gives himself such very shaky hangers? The hooks hold so long as the work of tearing continues, though one would think that this ought to bring down everything; they give way under a trifling shock so soon as that work is done. We have, therefore, a very unstable condition of equilibrium here, showing once m.ore with what delicate pre- cision the insect leaves its sheath. I said " tearing," for want of a better word. But it is not quite that. The term implies violence; and violence there cannot be any, because of the unsteady balance. Should the Locust, upset by his exertions, come to the ground, it would be all up with him. He would shrivel where he lies; or, at any rate, his organs of flight, being un- able to expand, would remain pitiful shreds. The Locust does not tear himself loose; he 412 The Locusts: the last Moult flows softly from his scabbard. It is as though he were forced out by a gentle spring. To return to the wings and wing-cases, which have made no apparent progress since leaving the sheaths. They are still stumps, with fine longitudinal seams, not much more than bits of rope. Their expansion, which will take more than three hours, is reserved for the end, when the insect is completely stripped and in its normal position. We have seen the Locust turn head up- permost. This upright position is enough to restore the natural arrangement of the wing-cases and wings. Being extremely flex- ible and bent by their own weight, they were hanging down with their loose end pointing towards the head of the Inverted insect. Now, still by virtue of their own weight, they are straightened and put the right way up. They are no longer curved like the petals of a flower, they are no longer in an Inverted position; but they still look miserably insig- nificant. In its perfect state, the wing is fan-shaped. A radiating cluster of strong nervures runs through it lengthwise and forms the frame- work of the fan, which is readily furled or 413 The Life of the Grasshopper unfurled. The Intervening spaces are crossed by Innumerable tiny bars which make of the whole a network of rectangular meshes. The wing-case, which Is coarser and much less expanded, repeats this structure in squares. In neither case does any of the mesh show during the rope's-end stage. All that we see is a few wrinkles, a few winding furrows, which tell us that the stumps are bundles of cunningly folded material reduced to their smallest volume. The expansion begins near the shoulder. Where at first nothing definite was to be distinguished, we soon see a diaphanous area subdivided into meshes of exquisite pre- cision. Little by little, with a slowness that defies observation even through the magnlfy- Ing-glass, this area increases in extent at the expense of the shapeless terminal roll. My eyes linger In vain on the confines of the two portions, the roll developing and the gauze already developed: I see nothing, see no more than I should see in a sheet of water. But wait a moment; and the tissue of squares stands out with perfect clearness. If we judged only by this first examina- tion, we should really think that an organ- 414 The Locusts: the last Moult izable fluid is abruptly congealing into a network of nervures; we should imagine that we were in the presence of a crystallization similar, in its suddenness, to that of a saline solution on the slide of a microscope. Well, no : things cannot be actually happening like that. Life does not perform its tasks so hastily. I detach a half-developed wing and turn the powerful eye of the microscope upon it. This time I am satisfied. On the confines where the network seemed to be gradually woven, that network was really in existence. I can plainly see the longitudinal nervures, already thick and strong; and I can also see, pale, it is true, and without relief, the cross- bars. I find them all in the terminal roll, of which I succeed in unfolding a few strips. It is obvious. The wing is not at this mo- ment a fabric on the loom, through which the procreative energies are driving their shuttle; it is a fabric already completed. All that it lacks to be perfect is expansion and stiffness, even as our linen needs only starch- ing and ironing. The flattening out is finished in three hours or more. The wings and wing-cases stand up on the Locust's back like a huge set of 415 The Life of the Grasshopper sails, sometimes colourless, sometimes pale- green, as are the Cicada's wings at the be- ginning. We are amazed at their size when we think of the paltry bundles that repre- sented them at first. How did so much stuff manage to find room there ! The fairy-tales tell us of a grain of hemp- seed that contained the underlinen of a prin- cess. Here is a grain that is even more astonishing. The one in the story took years and years to sprout and multiply and at last to yield the quantity of hemp required for the trousseau; the Locust's supplies a sumptuous set of sails in a short space of time. Slowly the proud crest, standing erect In four straight blades, acquires consistency and colour. The latter turns the requisite shade on the following day. For the first time the wings fold like a fan and lie in their places; the wing-cases lower their outer edge and form a gutter which falls over the sides. The transformation is finished. All that re- mains for the big Locust to do Is to harden his tissues still further and to darken the grey of his costume while revelling in the sun. Let us leave him to enjoy himself and re- trace our steps a little. 416 The Locusts: the last Moult The four stumps, which issued from their sheaths shortly after the corselet split its keel down the middle, contain, as we have seen, the wings and wing-cases, with their net- work of nervures. This network, if not per- fect, has at least the general plan of its numberless details mapped out. To unfurl these poor bundles and convert them into generous sails, it is enough that the organ- ism, acting in this case like a forcing-pump, should shoot a stream of humours, which have been kept in reserve for this moment, the hardest of all, into the little channels already prepared for their reception. With the channel marked out in advance, a slight injection is sufficient to explain the rapid spread. But what were the four strips of gauze while still contained in their sheaths? Are the wings spatules and the three-cornered pinions of the larva moulds whose creases, corners and sinuosities shape their contents in their own image and weave the tissues of the future wing and wing-case? If we had to do with a real instance of moulding, our brains could call a halt. We should say to ourselves that it was quite simple for the thing moulded to correspond with the shape 417 The Life of the Grasshopper of the mould. But our halt would be short lived, for the mould in Its turn would want explaining: we should have to seek for a solution of Its Infinite intricacies. Let us not go so far back; we should be utterly In the dark. Let us rather keep to facts that can be observed. I examine through the magnifying-glass a pinion of a larva ripe for transformation. I see a bundle of fairly thick nervures radi- ating fanwise. Other nervures, paler and finer, are set in the intermediate spaces. Lastly, the fabric is completed by a number of very short transversal lines, more delicate still and chevron-shaped. This, no doubt, gives a rough outline of the future wing-case ; but how different from the mature structure ! The arrange- ment of the radiating nervures, the skeleton of the edifice. Is not at all the same; the net- work formed by the transversal veins in no way suggests the complicated pattern which we shall see later. The rudimentary Is about to be succeeded by the Infinitely com- plex, the crude by the exquisitely perfect. The same remark applies to the wing-spatule and Its outcome, the final wing. It Is quite evident, when we have the pre- 418 The Locusts: the last Moult paratory and the ultimate stage before our eyes at the same time : the larva's pinion is not merely a mould which elaborates the ma- terial in its own image and shapes the wing- case upon the model of its hollow. No, the membrane which we are expecting is not yet inside in the form of a bundle which, when unfurled, will astonish us with the size and the extreme complexity of its texture. Or, to be accurate, it is there, but in a potential state. Before becoming a real thing, it is a virtual thing, which is nothing as yet, but which is capable of becoming something. It is there just as much as the oak is inside its acorn. A fine, transparent rim binds the free edge both of the embryo wing and the embryo wing-case. Under a powerful lens we can see a few uncertain outlines of the future lacework. This might well be the factory in which life intends to set its materials going. There is nothing else visible, nothing to suggest the prodigious network whose every mesh will shortly have its form and place determined for it with geometrical precision. There must therefore be something better and greater than a mould to make the or- 419 The Life of the Grasshopper ganlzable matter shape itself into a sheet of gauze and describe the inextricable laby- rinth of the nervation. There is a primary plan, an ideal pattern which assigns to each atom its precise place. Before the matter begins to move, the configuration is already virtually traced, the courses of the plastic currents are already mxarked out. The stones of our buildings are arranged in ac- cordance with the architect's considered plan; they form an ideal assemblage before exist- ing as a real assemblage. Similarly, a Lo- cust's wing, that sumptuous piece of lace emerging from a miserable sheath, speaks to us of another Architect, the Author of the plans which life must follow in its labours. The genesis of living creatures offers to our contemplation, in an infinity of ways, marvels far greater than those of the Acridian; but generally they pass unper- ceived, overshadowed as they are by the veil of time. The lapse of years, with its slow mysteries, robs us of the most astonishing spectacles, unless our minds be endowed with a stubborn patience. Here, by exception, things take place with a swiftness that arrests even a wavering attention. He who would, without wearisome delays, 420 The Locusts: the last Moult catch a glimpse of the Inconceivable dex- terity with which life does its work has but to go to the great Locust of the vines. The insect will show him that which, with their extreme slowness, the sprouting seed, the budding leaf and the blossoming flower hide from our curiosity. We cannot see a blade of grass grow; but we can easily witness the growth of a Locust's wings and wing-cases. We stand astounded at this sublime phan- tasmagoria of a grain of hemp-seed which In a few hours becomes a superb piece of linen. What a proud artist is life, driving its shuttle to weave the wings of a Locust, one of those insignificant Insects of which Pliny, long ago said: " In his tarn parvis, fere niiUis, qua vis, qua sapientia, quant inextricahilis per- fectisf' How well the old naturalist was Inspired on this occasion ! Let us repeat after him : " What power, what wisdom, what Inde- scribable perfection In the tiny corner of life v/hich the Locust of the vines has shown us ! " I have heard that a learned enquirer, to whom life was but a conflict of physical and 421 The Life of the Grasshopper chemical forces, did not despair of one day- obtaining artificial organizable matter: pro- toplasm, as the official jargon has it. Were it in my power, I should hasten to satisfy this ambitious person. Very well, be it so : you have thoroughly prepared your protoplasm. By dint of long hours of meditation, deep study, scrupulous care and inexhaustible patience, your wishes have been fulfilled; you have extracted from your apparatus an albuminous glair, which goes bad easily and stinks like the very devil in a few days' time : in short, filth. What do you propose to do with your product? Will you organize It? Will you give It the structure of a living edifice? Will you take a hypodermic syringe and inject it be- tween two impalpable films to obtain were it only the wing of a Gnat? For that Is more or less what the Locust does. He Injects his protoplasm between the two scales of the pinion; and the ma- terial becomes a wing-case, because It finds as a guide the Ideal archetype of which I spoke just now. It Is controlled In its In- tricate windings by a plan which existed before the injection, before the material Itself. 422 The Locusts: the last Moult Have you this archetype, this coordinator of forms, this primordial regulator, at the end of your syringe? No? Then throw away your product ! No life will ever spring from that chemical ordure. 423 CHAPTER XX THE FOAMY CICADELLA IN April, when the Swallow and the Cuckoo visit us, let us consider the fields for a while, keeping our eyes on the ground, as befits the eager observer of insect-life. We shall not fail to see, here and there, on the grass, little masses of white foam. It might easily be taken for a spray of frothy spittle from the lips of a passer-by; but there is so much of it that we soon abandon this first idea. Never would human saliva suffice for so lavish an expenditure of foam, even if some one with nothing better to do were to devote all his disgusting and misdirected zeal to the effort. While recognizing that man is blameless in the matter, the northern peasant has not relinquished the name suggested by the ap- pearance : he calls those strange flakes " Cuckoo-spit," after the bird whose note is then proclaiming the awakening of spring. 424 The Foamy Cicadella The vagrant creature, unequal to the toils and delights of housekeeping, ejects it at random, so they say, as it pays its flying visits to the homes of others, in search of a resting-place for its egg. The interpretation does credit to the Cuckoo's salivary powers, but not to the in- terpreter's intelligence. The other popular denomination is worse still: "Frog-spit!" My dear good people, what on earth has the Frog or his slaver to do with it? ^ The shrewder Provencal peasant also knows that vernal foam; but he is too cau- tious to give it any wild names. My rustic neighbours, when I ask them about Cuckoo- spit and Frog-spit, begin to smile and see nothing in those words but a poor joke. To my questions on the nature of the thing they reply : " I don't know." Exactly! That's the sort of answer I like, an answer not complicated with grotesque explanations. Would you know the real perpetrator of this spittle? Rummage about the frothy * Kirby and other English naturalists refer to Aphrophora spiirnaria as the Frothy Froghopper; but this is rather because the insect's outline and hopping- powers suggest those of a Frog, — Translator's Note. 425 The Life of the Grasshopper mass with a straw. You will extract a little yellow, pot-bellied, dumpy creature, shaped like a Cicada without wings. That's the foam-producer. When laid naked on another leaf, she brandishes the pointed tip of her little round paunch. This at once betrays the curious machine which we shall see at work presently. When older and still operating under the cover of its foam, the little thing becomes a nymph, turns green in colour and gives Itself stumps of wings fixed scarfwise on its sides. From underneath Its blunted head there pro- jects, w^hen it Is working, a little gimlet, a beak similar to that of the Cicadas. In its adult form the Insect Is, In fact, a sort of very small-sized Cicada, for which reason the entomologist capable of shaking off the trammels of nonsensical nomencla- ture calls it simply the Foamy Cicadella. For this euphonic name, the diminutive of Cicada, the others have substituted that hor- rible word Aphrophora. Orthodox science says, Aphrophora spumaria, meaning Foamy Foambearer. The ear Is none the better for this improvement. Let us content our- selves with Cicadella, which respects the tympanum and does not reduplicate the foam. 426 The Foamy CIcadella I have consulted my few books as to the habits of the CIcadella. They tell me that she punctures plants and makes the sap exude In foamy flakes. Under this cover, the insect lives sheltered from the heat. A work recently compiled has one curious piece of information : it tells me that I must get up early in the morning, inspect my crops, pick any twig with foam on it and at once plunge It Into a cauldron of boiling water. Oh, my poor CIcadella, this is a bad look- out! The author does not do things by halves. I see him rising before the dawn, lighting a stove on wheels and pushing his Infernal contrivance through the midst of his lucern, his clover and his peas, to boil you on the spot. He will have his work cut out for him. I remember a certain patch of sainfoin of which almost every stalk had Its foam-flakes. Had the stewlng-process been necessary, one might just as well have reaped the field and turned the whole crop Into herb- tea. Why these violent measures ? Are you so very dangerous to the harvest, my pretty little Cicada? They accuse you of draining the plant which you attack. Upon my word, they are right: you drain it almost as dry as 427 The Life of the Grasshopper the Flea does the Dog. But to touch an- other's grass — you know It: doesn't the fable say so? — is a heinous crime, an offence which can be punished by nothing less drastic than boiling water. Let us waste no more time on these agri- cultural entomologists with their murderous designs. To hear them talk, one would think that the insect has no right to live. Incapable of behaving like a ferocious land- owner who becomes filled with thoughts of massacre at the sight of a maggoty plum, I, more kindly, abandon my few rows of peas and beans to the Cicadella : she will leave me my share, I am convinced. Besides, the insignificant ones of the earth are not the least rich In talent, in an orig- inality of invention which will teach us much concerning the Infinite variety of Instinct. The Cicadella, In particular, possesses her recipes for aerated waters. Let us ask her by what process she succeeds In giving such a fine head of froth to her product, for the books that talk about boiling cauldrons and Cuckoo-spIt are silent on this subject, the only one worthy of narration. The foamy mass has no very definite shape and is hardly larger than a hazel-nut. It Is 428 The Foamy Cicadelia remarkably persistent even when the Insect Is not working at it any longer. Deprived of its manufacturer, who would not fail to keep it going, and placed on a watch-glass, it lasts for more than twenty-four hours with- out evaporating or losing its bubbles. This persistency is striking, compared with the rapidity with which soapsuds, for instance, disappear. Prolonged duration of the foam Is neces- sary to the Cicadella, who would exhaust herself in the constant renewal of her pro- ducts if her work were ordinary froth. Once the effervescent covering Is obtained, it Is essential that the insect should rest for a time, with no other task than to drink its fill and grow. And so the moisture converted Into froth possesses a certain stickiness, con- ducive to longevity. It Is slightly oily and trickles under one's finger like a weak solu- tion of gum. The bubbles are small and even, being all of the same dimensions. You can see that they have been scrupulously gauged, one by one; you suspect the presence of a graduated tube. Like our chemists and druggists, the insect must have Its drop-measures. A single Cicadella is usually crouching in- 429 The Life of the Grasshopper visible In the depths of the foam; sometimes there are two or three or more. In such cases, It Is a fortuitous association, the fabrics of the several workers being so close together that they merge into one common edifice. Let us see the work begin and, with the aid of a magnlfying-glass, follow the crea- ture's proceedings. With her sucker In- serted up to the hilt and her six short legs firmly fixed, the CIcadella remains motion- less, flat on her stomach on the long-suflering leaf. You expect to see froth Issuing from the edge of the well, effervescing under the action of the Insect's Implement, whose lancets, ascending and descending In turns and rubbing against each other like those of the Cicada, ought to make the sap foam as it is forced out. The froth, so it would seem, must come ready-made from the punc- ture. That is what the current descriptions of the CIcadella tell us ; that was how I my- self pictured it on the authority of the writers. All this is a huge mistake : the real thing Is much more ingenious. It Is a very clear liquid that comes up from the well, with no more trace of foam than in a dew- drop. Even so the Cicada, who possesses 430 The Foamy Cicadella similar tools, makes the spot at which she slakes her thirst give forth a limpid fluid, with not a vestige of froth to it. There- fore, notwithstanding its dexterity in sucking up liquids, the Cicadella's mouth-apparatus has nothing to do with the manufacture of the foamy mattress. It supplies the raw material; another implement works It up. What implement? Have patience and we shall see. The clear liquid rises imperceptibly and glides under the Insect, which at last is half inundated. The work begins again without delay. To make white of egg into a froth we have two methods: we can whip It, thus dividing the sticky fluid Into thin flakes and causing it to take in air In a network of cells; or we can blow into It and so Inject air-bubbles right Into the mass. Of these two methods, the Cicadella employs the sec- ond, which is less violent and more elegant. She blows her froth. But how Is the blowing done ? The Insect seems incapable of It, being devoid of any air-mechanism similar to that of the lungs. To breathe with tracheae and to blow like a bellows are Incompatible actions. Agreed; but be sure that, if the insect 431 The Life of the Grasshopper needs a blast of air for its manufactures, the blowing-machine will be there, most inge- niously contrived. This machine the Cica- della possesses at the tip of her abdomen, at the end of the Intestine. Here, split length- wise In the shape of a Y, a little pocket opens and shuts In turns, a pocket whose two lips close hermetically when joined. Having said this, let us watch the per- formance. The Insect lifts the tip of Its abdomen out of the bath In which It Is swim- ming. The pocket opens, sucks In the air of the atmosphere till It Is full, then closes and dives down, the richer by its prize. In- side the liquid, the apparatus contracts. The captive air escapes as from a nozzle and produces a first bubble of froth. Forth- with the air-pocket returns to the upper air, opens, takes In a fresh load and goes down again closed, to Immerse Itself once more and blow in its gas. A new bubble is pro- duced. And so It goes on with chronometrlcal regularity, from second to second, the blow- ing-machine swinging upwards to open Its valve and fill Itself with air, downwards to dive Into the liquid and send out Its gaseous contents. Such Is the air-measurer, the drop- 432 The Foamy Cicadella glass which accounts for the evenness of the frothy bubbles. Ulysses, the favourite of the gods, re- ceived from the storm-dispenser, /Eolus, bags In which the winds were confined. The carelessness of his crew, who untied the bags to find out what they contained, let loose a tempest which destroyed the fleet. I have seen those mythological wind-filled bags; I saw them years ago, when I was a child. A peripatetic tinker, a son of Calabria, had set up between two stones the crucible in which a tin soup-tureen and plates were to be remelted. iEolus did the blowing, ^^olus in the person of a little dark- skinned boy who, squatting on his heels, forced air towards the forge by alter- nately squeezing two goatskin bags, one on the right and one on the left. Thus must the prehistoric bronze-smelters have per- formed their task, they whose workshops and whose remains of copper-slag I find on the hills near my home : the blast of their fur- naces was produced by these Inflated skins. The machine employed by my ^olus is pathetically simple. The hide of a goat, with the hair left on, is practically all that is necessary. It Is a bag fastened at the 433 The Life of the Grasshopper bottom over a nozzle, open at the top and supplied, by way of lips, with two little boards which, when brought together, close up the whole apparatus. These two stiff lips are each furnished with a leather handle, one for the thumb, the other for the four remaining fingers. The hand opens; the lips of the bag part and it fills with air. The hand closes and brings the boards together; the air imprisoned In the compressed bag escapes by the nozzle. The alternate work- ing of the two bags gives a continuous blast. Apart from continuity, which is not a favourable condition when the gas has to be discharged in small bubbles, the Clca- della's bellows works like the Calabrlan tinker's. It is a flexible pocket with stiff lips, which alternately part and unite, opening to let the air enter and closing to keep It Im- prisoned. The contraction of the sides takes the place of the shrinking of the bag and puffs out the gaseous contents when the pocket Is Immersed. He certainly had a lucky Inspiration who first thought of confining the wind In a bag, as mythology tells us that i^olus did. The goatskin turned Into a bellows gave us our metals, the essential matter whereof our 434 The Foamy Cicadella tools are made. Well, in this art of expelling air, an enormous source of progress, the Ci- cadella was the pioneer. She was blowing her froth before Tubalcain thought of urging the fire of his forge with a leather pouch. She was the first to invent bellows. When, bubble by bubble, the foamy wrap- per covers the insect to a height which the uplifted tip of her belly is unable to reach, it is no longer possible to take In air and the effervescence stops. Nevertheless, the gimlet that extracts the sap goes on working, for nourishment must be obtained. As a rule then, in the sloping part, the superfluous liquid, that which is not converted into foam, collects and forms a drop of perfectly clear liquid. What does this limpid fluid lack In order to turn white and effervesce? Nothing but air blown into It, one would think. I am able to substitute my own devices for the Cicadella's syringe. I place between my lips a very slender glass tube and with delicate puffs send my breath Into the drop of moisture. To my great surprise. It does not froth up. The result Is just the same as that which I should have with plain water from the tap. 435 The Life of the Grasshopper Instead of a plentiful, lasting, slow-sub- siding foam, like that with which the insect covers itself, all that I obtain is a miserable ring of bubbles, which burst as soon as they appear. And I am equally unsuccessful with the liquid which the Cicadella collects under her abdomen at the start, before working her bellows. What is wrong in each case? The foamy product and its generating liquid shall tell us. The first is oily to the touch, gummy and as fluid as, for instance, a weak solution of albumen would be; the second flows as read- ily as plain water. The Cicadella therefore does not draw from her well a liquid liable to effervesce merely by the action of the blow- pocket; she adds something to what oozes from the puncture, adds a viscous element which gives cohesion and makes frothing pos- sible, even as a boy adds soap to the water which he blows into iridescent bubbles through a straw. Where then does the insect keep its soap- works, its manufactory of the effervescent element? Evidently in the blow-pocket Itself. It is here that the intestine ends and here that albuminous products, furnished either by the digestive canal or by special glands, 436 The Foamy Cicadella can be expelled In infinitesimal doses. Each whiff sent out Is thus accompanied by a trifle of adhesive matter, which dissolves in the water, making it sticky and enabling it to retain the captive air in permanent bubbles. The Cicadella covers herself with an icing of which her intestine is to some extent the manufacturer. This method brings us back to the Industry of the lily-dweller, the grub vv^hich makes Itself a loathsome armour out of its excre- tions; ^ but what a distance between the heap of ordure w^hlch it wears on its back and the CIcadella's aerated mattress ! Another fact, more difficult to explain, attracts our attention. A multitude of low- growing, herbaceous plants, whose sap starts flowing in April, suit the frothy Insect, without distinction of species, genus or family. I could almost make a list of the non-ligneous vegetation of my neighbourhood by cataloguing the plants on which the little creature's foam is to be found in greater or lesser abundance. A few experiments will tell us how indifferent the Cicadella is to both * The larva of the Lily-beetle {Crioceris merdigera)^ the essay on which insect has not yet been translated into English. — Translator's Note. 437 The Life of the Grasshopper the nature and the properties of the plant which she adopts as her home. I pick the insect out of its froth with the tip of a hair-pencil and place it on some other plant, of an opposite flavour, letting the strong come after the mild, the spicy after the insipid, the bitter after the sweet. The new encampment is accepted without hesitation and soon covered with foam. For instance, a Cicadella taken from the bean, which has a neutral flavour, thrives excel- lently on the spurges, full of pungent milky sap, and particularly on Euphorbia serrata, the narrow notch-leaved spurge, which is one of her favourite dwelling-places. And she is equally satisfied when moved from the highly-spiced spurge to the comparatively flavourless bean. This indifference Is surprising when we re- flect how scrupulously faithful other insects are to their plants. There are undoubtedly stomachs expressly made to drink corrosive and assimilate toxic matters. The caterpillar of Acherontia atropos, the Death's-head Hawk-moth, eats its fill of potato-leaves, which are seasoned with solanin; the cater- pillar of the Spurge-moth browses in these parts on the upright red spurge (Euphorbia 438 The Foamy Cicadella characias), whose milk produces much the same effect as red-hot iron on the tongue; but neither one nor the other would pass from these narcotics or these caustics to ut- terly insipid fare. How does the Cicadella manage to feed on anything and everything, for she evi- dently obtains nourishment while putting a head on her liquid? I see her thrive, either of her own accord or by my devices, on the common buttercup {Ranunculus acris)^ which has a flavour unequalled save by Cayenne pepper; on the Italian arum {Arum itali- cum), the veriest particle of whose leaves is enough to burn the lips; on the traveller's joy, or virgin's bower {Clematis vitalba), the famous beggars' herb, which reddens the skin and produces the sores in request among our sham cripples. After these highly- seasoned condiments, she will promptly ac- cept the mild sainfoin, the scented savory, the bitter dandelion, the sweet field eringo, in short, anything that I put before her, whether full-flavoured or tasteless. As a matter of fact, this strange catho- licity of diet might well be only apparent. When the Cicadella punctures this or that herb, of whatever species, all that she does 439 The Life of the Grasshopper is to extract an almost neutral liquid, just as the roots draw it from the soil; she does not admit to her fountain the fluids worked up into essential principles. The liquid that trickles forth under the insect's gimlet and forms a bead at the bottom of the foamy mass Is perfectly clear. I have gathered this drop on the spurge, the arum, the clematis and the buttercup. I expected to find a fire-water, pungent as the sap of those different plants. Well, it is nothing of the kind; it lacks all savour; it is water or little more. And this insipid stuff has issued from a reservoir of vitriol. If I prick the spurge with a fine needle, that which rises from the puncture is a white, milky drop, tasting horribly bitter. When the Cicadella pushes In her drill, a clear, flavourless fluid oozes out. The two opera- tions seem to be directed towards different sources. How does she manage to draw a liquid that is clear and harmless from the same barrel whence my needle brings up some- thing milky and burning? Can the Cica- della, with her Instrument, that Incompara- ble alembic, divide the fierce fluid into two, admitting the neutral and rejecting the pep- 440 The Foamy Cicadella pery? Can she be drawing on certain vessels whose sap, not yet elaborated, has not ac- quired its final virulence? The delicate vegetable anatomy is helpless in the presence of the tiny creature's pump. I give up the problem. When the Cicadella is exploring the spurge, as frequently happens, she has a seri- ous reason for not admitting to her fountain all that would be yielded by simple bleeding, such as my needle would produce. The milky juice of the plant would be fatal to her. I gather a drop or two of the liquid that trickles from a cut stalk and instal a Cica- della in it. The insect is not comfortable : I can see this by its efforts to escape. My hair-pencil pushes the fugitive back into the pool of milk, rich in dissolved rubber. Soon this rubber settles into clots similar to crumbs of cheese; the insect's legs become clad in gaiters that seem made of casein; a coating of gum obstructs the breathing-valves; possi- bly also the extremely delicate skin is hurt by the blistering qualities of the milky sap. If kept for some time in that environment, the Cicadella dies. Even so would she die if her gimlet, work- ing simply as a needle, brought the milk of 441 The Life of the Grasshopper the spurge to the surface. A sifting takes place then, which allows almost pure water to issue from the source that gives the where- withal for making the froth. A subtle exhaustion-process, whose mechanism is hid- den from our curiosity, a piston-play of un- rivalled delicacy, effects this marvellous work of purification. Water is always water, whether it come from the stagnant pool or the clear stream, from a poisonous liquid or a healing infu- sion; and it possesses the same properties, when it Is rid of Its impurities by distillation. In like manner, the sap, whether furnished by the spurge or the bean, the clematis or the sainfoin, the buttercup or the borage, is of the same watery nature when the CIcadella's syphon, by a reducing-process which would be the envy of our stills, has deprived it of its peculiar properties, which vary so greatly in different plants. This would explain how the insect makes Its froth rise on the first plant that It comes across. Everything suits it, because Its appa- ratus reduces any sap to the condition of plain water. The Inimitable well-sinker is able to produce the limpid from the cloudy and the harmless from the toxic. 442 The Foamy Cicadella It may possibly happen that the insect's well supplies water that is not quite pure. If left to evaporate in a watch-glass, the clear drop that trickles from the mass of foam yields a thin white residue, which dis- solves by effervescence in nitric acid. This residue might well be carbonate of potash. I also suspect the presence of traces of albumen. Obviously, the Cicadella finds something to feed on at the bottom of the puncture. Now what does she consume? To all ap- pearances, something with an albuminous basis, for the pigmy herself is, for the most part, but a grain of similar matter. This element is plentiful in all plants; and it is probable that the insect uses it lavishly to make up for the expenditure of gum needed for the formation of froth. Some albu- minous product, perfected in the digestive canal and discharged by the intestine as and when the blow-pocket expels its bubble of air, might well give the liquid the power of swelling into a foam that lasts for a long time. If we ask ourselves what advantage the Cicadella derives from her mass of froth, a very excellent answer is at once suggested: 443 The Life of the Grasshopper the insect keeps itself cool under that shelter, hides itself from the eyes of its persecutors and is protected against the rays of the sun and the attacks of parasites. The Lily-beetle makes a similar use of the mantle of her own dirt; but she, most unhappily for herself, flings off her nasty cloak and descends naked from the plant to the ground, where she has to bury herself to slaver her cocoon. At this critical mo- ment, the Flies lie in wait for her and en- trust her with their eggs, the germs of para- sites which will eat into her body. The Cicadella is better-advised and alto- gether escapes the dangers attendant on a re- moval. Subject to certain summary changes which never interrupt her activity, she as- sumes the adult form in the very heart of her bastion, under the shelter of a viscous rampart capable of repelling any assailant. Here she enjoys perfect security when the difficult hour has come for tearing off her old skin and putting on another, brand-new and more decorative; here she finds profound peace for her excoriation and for the dis- play of the attire of a riper age. The insect does not leave its cool cover- ing until it is grown up, when it appears in 444 The Foamy Cicadella the form of a pretty httle, brown-striped Cicadella. It is then able to take enormous and sudden leaps, which carry it far from the aggressor; and it leads an easy life, un- troubled by the foe. Looked upon as a system of defence, the frothy stronghold is indeed a magnificent in- vention, much superior to the squalid work of the invader of the lily. And, strange to say, the system has no imitators among the genera most nearly allied to the froth- blower. In her larval form, the Asparagus-beetle is victimized by the Fly because she does not follow the example of her cousin, the Lily- beetle, and clothe herself in her own drop- pings. Even so, on the grass, on the trees displaying their tender leaves, other Cica- dellae abound, no less exposed to danger from the Warbler seeking a succulent morsel for his little ones; and, as they draw out the sap through the punctures made by their suckers, not one of them thinks of making it effervesce. Yet they too possess the elevator- pump, which they all work in the same manner; only they do not know how to turn the end of their intestine into a bellows. Why not? Because instincts are not to be 445 The Life of the Grasshopper acquired. They are primordial aptitudes, bestowed here and denied there; time cannot awaken them by a slow incubation, nor are they decreed by any similarity of organization. 446 INDEX Acherontia atropos {see Death's-head Hawk- moth) Adder, 122, 125, 206 ^sop, 6-7 Agrion, 273 Alpine Analota, 231-235, 238, 299, 373 Ameles decolor {see Grey Mantis) Ammonite, 273 Ammophila holosericea, 202-204 Anacreon, 13 Analota alpina {see Alpine Analota) Anianus, 5« Anoxia pilosa, 290 Ant, 1-2, 4-5, 7, 9-24, 176- 178, i8i, 183, 187-190, 199, 263, 298, 307, 321- 323 Anthidium, 203 Anthophora, 109 Anthrax, 100 Ant-lion, 307 Aphis, 178 Aphrophora spumaria {see Foamy Cicadella) Aristotle, 50-51. 53-55, 3^6 Ash Cicada, 59, 66-75, 80, 94 Asparagus-beetle, 445 Ass, 138, 257 B Badger, 308 Bat, 201-202 Bee, 92, 121, 136, 146, 180, 202, 247, 251, 256 Beetle {see also the va- rieties), 22, 146, 2SS-2S^t 360 Bellot, M., 232 Beranger, Pierre Jean de, 4«, 13 Black Cicada, 59, 73 Blue-winged Locust, 214- 217, 381-383, 389, 397- 400 Bolboceras gallicus, 255- 256 Bombyx, 205 Bordeaux Cricket, 309- 310, 345-346 Buffon, Georges Louis Leclerc de, 253 Bull, 69, 249 Bull, the author's Dog, 133-134 Buprestis, 31-33 Burying-beetle {see Necro- phorus) Butterfly {see also the va- rieties), 121, 125, 146, 183, 198-199,256,302-305 447 Index Cabbage Butterfly {see White Cabbage Butter- fly) Cacan {see Ash Cicada) Callot, Jacques, 194 Caloptenus italicus {see Italian Locust) Camel, 362 Capon, 188 Capricorn, 31-33, 255-256 Cassida {see Tortoise- beetle) Cat, 3, 140, 196, 282.
