THE SACRED BEETLE: THE BALL There is no need to return to the Sacred Beetle working in the daylight or consuming his booty underground, either alone, as usually happens, or in the company of a guest: what I have said about this in a former chapter is enough; and further observations would give no new information of special interest. There is only one point which deserves attention. This is the method of constructing the spherical pellet, consisting merely of provisions which the Beetle collects for his own use and conveys to an underground dining-room excavated at a convenient spot. My present cages, which are much better arranged than those which I had at first, enable us to watch the operation at our leisure; and this operation will furnish data which will be of the greatest value later in explaining the mysterious structure of the nest. Let us then once more watch the Sacred Beetle as he busies himself with his victuals. I supply fresh provisions, derived from the Mule or, better, the Sheep. The scent of the heap carries the news far and wide. The Beetles hasten up from every direction, extending and waving the russet feathers of their antennæ, a sign of acute excitement. Those who were dozing underground split the sandy ceiling and sally forth from their cellars. They are now all at the banquet, [ ]not without quarrels among neighbours, who fight for the best bits and knock one another over with sudden back-handers from their broad fore-legs. Things calm down; and, without further disputes for the moment, each gets all that he can out of the spot where he happens to be. 43 The foundation of the structure is, as a rule, a bit that is almost round of itself. This is the kernel which, enlarged by successive layers, will become the ultimate ball, the size of an apricot. Having tested it and found it suitable, the owner leaves it as it is; or, at other times, he may clean it a little, scraping the outside, which is rough with bits of sand. It is now a question of constructing the ball upon this foundation. The tools are the six-toothed rake of the semicircular shield and the broad shovels of the fore-legs, which are likewise armed on the outer edge with strong teeth, five in number. Without for a moment letting go of the kernel, which is held in his four hind-legs, more particularly those of the third, the longest pair, the Beetle turns round slowly from side to side on the top of his embryo pellet and selects from the heap around him the materials for increasing its size. His sharp-edged forehead peels, cuts, digs and rakes; his fore-legs work in unison, gathering and drawing up an armful which is at once placed upon the central mass and patted down. A few vigorous applications of the toothed shovels press the new layer into position. And so, with armful after armful carefully added on top, beneath and at the sides, the original pill grows into a big ball. While working, the builder never leaves the dome of his edifice: he revolves on his own axis, if he wants to give his attention to any lateral part; to shape the lower [ ]portion, he bends down to the point where it touches the ground; but from beginning to end the sphere never moves on its base and the Beetle never relaxes his hold. 44 To obtain a perfectly round form, we need the potter’s wheel, whose rotation makes up for our want of skill; to enlarge his snowball and make it into the enormous sphere which he will end by being unable to move, the schoolboy rolls it in the snow: the rolling gives it the regularity which the direct work of the hands, guided by an inexperienced eye, would not. More dexterous than we, the Sacred Beetle can dispense with either rolling or rotation; he moulds his ball by means of superadded layers, without shifting its place and without even descending for an instant from the top of his dome to view the whole structure from the requisite distance. The compasses of his bow-legs, a living pair of callipers which measure and check the curve, are sufficient for his purpose. It is only with extreme caution, however, that I introduce these callipers, as I am perfectly convinced, by a host of facts, that instinct has no need of special tools. If further proof were wanted, here it is. The male Scarab’s hind-legs are perceptibly bowed; the female’s, on the contrary, are almost straight, though she is much the cleverer and is able, as we shall see presently, to produce masterpieces whose exquisite form far surpasses that of a monotonous sphere. If the curved compasses play but a secondary part in the matter and perhaps no part at all, what is the guiding principle of this sphericity? If one merely took into consideration the insect’s organism and the circumstances in which the work is done, I see absolutely none. We must go back farther, we must go back to the innate genius, the instinct that guides the tool. The Scarab [ ]has a natural gift for making spheres, just as the Hive-bee has a natural gift for making hexagonal prisms. Both achieve geometrical perfection in their work and are independent of any special mechanism which would force upon them the particular shape attained. 45 For the time being, keep this in mind: the Sacred Beetle makes his ball by placing next to each other armful after armful of the materials which he has collected; he builds it up without moving it, without turning it round. He fashions the dung with the pressure of his fore-arms as the modeller in our studios fashions his clay with the pressure of his thumb. And the result is not an approximate sphere, with a lumpy surface; it is a perfect sphere, which our human manufacturers would not disown. The time has come for retiring with the booty so that we may bury it farther away, at no great depth, and consume it in peace. The owner, therefore, draws his ball out of the dung-yard; and, in accordance with ancient usage, begins straightway to roll it about on the ground, a little at random. Any one who was not present at the beginning and who now saw the ball rolling along, with the insect pushing it backwards, would naturally imagine that the round shape resulted from this method of transport. It rolls, therefore it becomes round, even as a shapeless lump of clay would soon become round if trundled in the same way. Though apparently logical, the idea is erroneous in every respect: we have just seen this perfect sphericity acquired before the ball moved from the spot. The rolling therefore has nothing to do with this geometrical accuracy; it merely hardens the surface into a tough crust and polishes it a little, if only by working into the substance of the pellet any coarse bits that might have made it rough at the beginning. Between the pill that has been rolled for hours and the pill that is stationary in the dung-yard there is no difference in configuration. What is the advantage of this particular shape, which is invariably adopted at the very outset of the work? Does the Scarab derive any benefit from the circular form? Your spectacles would have to be made of walnut-shells if you failed to see that the insect is brilliantly inspired when it kneads its cake into a ball. These victuals, the meagrest of meagre pittances from the point of view of nourishment, for the Sheep’s fourfold stomach has already extracted pretty nearly all the assimilable matter, have to make up in quantity for what they lack in quality. It is the same with various other Dung-beetles. They are all insatiable gluttons; they all need a much larger amount of food than their modest dimensions would lead us to suspect. The Spanish Copris, no bigger than a good-sized hazel-nut, accumulates underground, for a single meal, a pie as big as my fist; the Stercoraceous Geotrupes hoards in his hole a sausage nine inches long and as wide as the neck of a claret-bottle. These mighty eaters have an easy time of it. They establish themselves immediately under the heap dropped by some standing Mule. Here they dig passages and dining-rooms. The provisions are at the door of the house; they form a roof for it. All that you have to do is to bring them in, armful by armful, taking only as much as you can carry comfortably, for you can go on fetching more as long as you like. In this way, scandalous quantities of food are unobtrusively stored away in peaceful manors whose presence no outward sign betrays.[ ] 47 The Sacred Beetle is not so fortunate as to have his cottage underneath the heap where the victuals are collected. He is of a vagabond temperament; and, when his work is over, he has no great inclination for the company of those arrant thieves, his kinsmen. He has therefore to travel to a distance with what he has secured, in quest of a site where he can establish himself alone. His stock of provisions, it is true, is comparatively modest: it is not to be mentioned in the same breath as the Copris’ enormous cakes or the Geotrupes’ fat sausages. No matter: modest though it be, its weight and bulk are too much for the strength of any Beetle that might think of carrying it direct. It is too heavy, ever so much too heavy, for him to take between his legs and fly away with, nor could he possibly drag it, gripped in his mandibles. If the hermit, eager to withdraw from the world, wished to make use of direct means of conveyance, there would be only one method by which he could accumulate in his far-off cell food enough for even a single day: that would be to carry load after load on the wing, each load being proportionate to his strength. But what a number of journeys that would involve! What a lot of time would be wasted in this piecemeal harvesting! Besides, when he went back, would he not find the table already cleared? Think of the number of guests who were giving it their attention! The opportunity is a good one; it may not occur again for a long while. We must make the most of it without delay; the thing to do is to secure enough now to stock our larder for at least a day. But how to set about it? Nothing could be simpler. What we cannot carry we drag; what we cannot drag we cart by rolling it along, as witness all our wheeled conveyances. The Sacred Beetle therefore chooses the sphere [ ]as a means of transport. It is the best shape of all for rolling; it needs no axle-tree; it adapts itself admirably to the diverse inequalities of the ground and, at each point of its surface, provides the necessary leverage for the least expenditure of effort. Such is the mechanical problem which the pill-roller solves. The spherical form of his treasure is not the effect of the rolling: it precedes it; it is modelled precisely with a view to that method of conveyance, which is to make the carriage of the heavy load feasible. 48 The Sacred Beetle is a passionate lover of the sun, whose image he copies in the radiating notches of his rounded shield. He needs the bright light in order to make the most of the heap whence he extracts first provisions and next materials for nest-building. The other Dung-beetles—Geotrupes, Copres, Onites, Onthophagi—for the most part have dark, mysterious habits; they work unseen under the roof of excrement; they do not begin their quest until night is at hand and the last glimmer of twilight is fading. The more trustful Scarab both seeks and finds amid the gladness of the noonday sun; he works his bit of ground quite openly and reaps his harvest in the hottest and brightest hours of the day. His ebon breastplate is glittering on top of the heap at times when there is naught to indicate the presence of numerous fellow-workers, belonging to other genera, who are busy underneath, carving themselves their share of the lower strata. Darkness for others, but for him the light! This love of the unscreened sun has its blissful side, as the insect, drunk with heat, shows from time to time by exultant transports; but it has also certain disadvantages. I have never witnessed any quarrel at harvest-time [ ]between next-door neighbours, when these were Copres or Geotrupes. Working in the dark, each is ignorant of what is happening beside him. The rich morsel secured by one of them cannot arouse the envy of his neighbours, since it is not perceived. This perhaps explains the pacific relations among Dung-beetles who work in the gloomy depths of the heap. 49 My suspicions are not unfounded. Robbery, the execrable right of the strongest, is not the exclusive prerogative of the human brute: animals also practise it; and the Sacred Beetle is a notorious offender. As the work is done in the open, every one knows or is able to find out what his companions are doing. They are mutually envious of each other’s pills; and scuffles take place between proprietors wishing to leave the yard and plunderers who find it more convenient to rob their fellows than to set to work and knead loaves for themselves. On guard on the top of his treasure, the owner of a ball will face his assailant, who is trying to climb up, and push him into space with a stroke from his stout fore-arms. The thief is flung on his back and flounders about for a moment, but he is soon up and back again. The struggle is renewed. Right does not always win, in which case the robber makes off with his prize and the victim returns to the heap to make himself another pill. It is not unusual for a third thief to appear upon the scene during the fight and settle matters between the litigants by carrying off the property at issue. I am inclined to think that it was affrays of this sort that gave rise to the childish story of the Sacred Beetles who were called to the rescue and came to lend a hand to their brothers in distress. Brazen footpads were taken for kindly helpers.[ ] 50 The Sacred Beetle then is an inveterate thief; he shares the tastes of the Bedouin Arab, his fellow-countryman in Africa; he too is addicted to raiding. In his case, hunger and dearth, both evil counsellors, cannot be invoked as an explanation of this moral obliquity. Provisions are plentiful in my cages; certainly, in their days of liberty, my captives never lived in the midst of such abundance; and yet affrays are of frequent occurrence. They fight hotly-contested battles for the loaves, just as though bread were lacking. Poverty has nothing to do with it, for very often the thief abandons his booty after rolling it for a few seconds. They steal for the pleasure of stealing. As La Fontaine well says, there is 1 … double profit à faire: Son bien premièrement; et puis le mal d’autrui. 2 In view of this propensity for thieving, what is the best thing that a Scarab can do when he has conscientiously made his ball? Obviously, to shun his fellows, to leave the premises and get away to a distant spot where he can consume his provisions in the depths of some hiding-place. This is what he does; and he loses no time in doing it: he knows his kinsmen too well. Here we see the necessity for an easy method of conveyance, so that sufficient provisions may be carted in a single journey and as swiftly as possible. The Sacred Beetle likes working in the bright light, in the sunshine. His profits therefore, made in full view of everybody, are no secret to any of the workers who have hurried to the [ ]same heap. Thus is envy kindled; thus it becomes imperative to retire to a distance, in order to avoid being robbed. This speedy retreat demands a convenient means of transport; and that is obtained by the spherical form given to the materials collected. 51 Here is the conclusion, unexpected but very logical and I would even say obvious: the Sacred Beetle shapes his provisions into a ball because he is an ardent lover of the sun. The various Dung-beetles who work in broad daylight, the Gymnopleuri and Sisyphi of my district, conform to the same mechanical principle: they all know the advantages of a sphere, the best rolling-apparatus; they all practise the art of pill-making. The other Dung-beetles, who work in the dark, do nothing of the kind: their accumulations of food are shapeless. Life in the vivarium supplies us with some other facts which are not undeserving of the commentator’s attention. We have said that, when fresh provisions are supplied, the Sacred Beetles who are roaming about come running up eagerly to the smoking fare. The rich effluvia also speedily attract those who are slumbering in their burrows. Little mounds of sand pop up here and there, cracking as though for an eruption, and we see new guests emerge, wiping the dust from their eyes with the flat of their feet. Neither their dozing in that underground room nor the thick roof of their dwelling has succeeded in foiling their keenness of scent: those who have had to unearth themselves reach the lump almost as quickly as the others. These details remind us of certain facts noted, not without surprise, by a host of observers on the sunny beaches at Cette, Palavas, the Golfe Juan and the North African coast, down to the lonely Sahara. Here the [ ]Sacred Beetle and his kinsmen—the Half-spotted Scarab, the Pock-marked Scarab and others—swarm, becoming more vigorous and more active in proportion as the climate grows hotter. They abound; and yet very often not one shows himself; the entomologist’s practised eye fails to discover a single specimen. 52 But now see things change. Seized with an urgent physiological need, you leave your party unobtrusively and retire behind the bushes. You have hardly stood up, hardly begun to adjust your dress, when—whoosh!—here comes one, here come three, here come ten, appearing suddenly you know not whence, and swoop upon the provender. Have they hastened from afar, these bustling scavengers? Certainly not. Had they been apprised at a great distance by their sense of smell, which is not in itself impossible, they would not have had time to reach the quite recent windfall so promptly. It follows, therefore, that they were close by, within a radius of ten or twenty yards, hidden underground and dozing. A scent that is ever awake, even in the lethargy of sleep, told them, down in their burrows, of the happy event; and, splitting their ceilings, they hurry up forthwith. In less time than the incident takes to relate, a swarming population enlivens what was but now a desert. A keen and vigilant scent is the Beetle’s, we must admit; a scent which is always in operation. The Dog smells the truffle through the soil, but he is awake; the pill-roller smells his favourite fare through the ground in the opposite direction, but he is asleep. Which of the two has the subtler scent? Science flings wide her net, welcoming even filth; and truth soars at heights where nothing can soil her. The reader will therefore be good enough to excuse certain [ ]details which cannot be avoided in a history of the Dung-beetle; he will show some indulgence for what has gone before and what will follow. The revolting workshop of the insect that manipulates ordure will lead perhaps to loftier ideas than would the perfumer’s factory with its jasmine and patchouli. 53 I have accused the Sacred Beetle of being an insatiable gormandizer. It is time to prove what I said. In my cages, which are too small to allow of much pill-rolling, my boarders often scorn to accumulate provisions and confine themselves to eating where they are. It is a good opportunity for us: the meal taken in public will tell us better than the underground banquet what a Dung-beetle’s stomach can do. On a very still and sultry day—these are the conditions most favourable to my anchorites’ gastronomic joys—I observe one of the diners in the open air, from eight o’clock in the morning until eight o’clock at night. Watch in hand, I time the glutton. He appears to have come across a morsel greatly to his taste, for, during those twelve hours, he never stops feasting, but remains glued to the table, absolutely stationary. At eight o’clock in the evening, I pay him a last visit. His appetite seems undiminished; I find him in as fine fettle as at the start. The banquet then must have gone on some time longer, until the dish had disappeared entirely. In fact, next morning there was no sign of my Beetle; and, of the sumptuous repast begun on the previous day, naught remained but crumbs. To eat the clock round is no small feat of gluttony; but the present instance shows a much more remarkable feat of digestion. While matter is continuously being chewed and swallowed by the insect in front, it is [ ]reappearing, no less continuously, behind, deprived of its nutritive particles and spun into a thin black cord, similar to cobbler’s thread. The Scarab never evacuates except at table, so quickly are his digestive operations performed. The wire-drawing apparatus begins to work at the first few mouthfuls; it ceases soon after the last. Without a break from beginning to end of the meal, the slender cord, ever appended to the discharging orifice, goes on piling itself into a heap which can easily be unrolled so long as there is no sign of desiccation. 54 The working is as regular as that of a chronometer. Every minute, or rather, to be exact, every four-and-fifty seconds, a discharge takes place and the thread is lengthened by three to four millimetres. At long intervals I employ my tweezers, remove the cord and unroll the mass along a graduated rule, in order to measure the amount produced. The total for twelve hours is 2·88 metres. As the meal and its necessary complement, the work of the digestive apparatus, went on for some time longer after my last visit, which was paid at eight o’clock in the evening by lantern-light, my Beetle must have spun an unbroken stercoraceous cord well over three yards in length. 3 4 Given the diameter and the length of the thread, it is easy to calculate its volume. Nor is it difficult to arrive at the exact volume of the insect by measuring the quantity of water which it displaces when immersed in a narrow cylinder. The figures thus obtained are not devoid of interest: they tell us that, at a single bout of eating, in a dozen hours, the Sacred Beetle digests very nearly his own bulk in food. What a stomach! And, [ ]above all, what rapidity, what power of digestion! From the very first mouthfuls, the residuum forms itself into a thread that stretches and stretches indefinitely as long as the meal lasts. In that amazing laboratory, which perhaps never puts up its shutters, unless it be when victuals are lacking, the material merely passes through, is at once treated by the stomach’s reagents and at once exhausted. One may well believe that an apparatus which sanifies filth so quickly has some part to play in the public health. We shall have occasion to return to this important subject. 55 About HackerNoon Book Series: We bring you the most important technical, scientific, and insightful public domain books.
