Buprestidae

“ Buphaga, bū′fā-ga, n. a small genus of African perching birds, nearly related to the starlings, feeding on the larvæ of gadflies and the like, which they find on the backs of cattle, camels, &c.—Also Beef-eater and Ox-pecker. [Gr., bous, an ox, phagein, to eat.]
Buprestis, bū-pres′tis, n. a genus of beetles, typical of a large family, Buprestidæ, those occurring in warmer countries having lively colour and metallic sheen—some known as Golden Beetles. ”

“ The beetles, after being caught, are stung in the chief articulation of the body, that, namely, between the pro- and mesothorax. Cerceris bupresticida confines itself exclusively to beetles of the family Buprestidae. It was by observations on this Insect that Dufour first discovered the fact that the Insects stored up do not decay: he thought, however, that this was due to the liquid injected by the wasp exercising some antiseptic power; but the observations of Fabre have shown that the preservation in a fresh state is due to life not being extinguished ”

“ In the Catalogue of the Coleoptera of Europe and the Mediterranean Basin, by M. de Marseul (1863) , we find 317 species of Buprestidæ enumerated, although {496}the district in question only forms a part of the Palæarctic region, which would thus seem to possess its full proportion of the species of this family. Confining ourselves to the generic forms, we find far less difference than usual between the numbers possessed by the tropical and the temperate regions; the richest being the Australian, with 47 genera, 20 of which are peculiar ”

“ The Buprestidæ walk heavily, but fly with the greatest ease during the heat of the sun, and settle on the trunks of trees exposed to its 515 rays. In Europe, and especially in the North, they are very rare, and of very small size. They must be looked for on birch-trees, whose white colour seems to attract them. In the hottest parts of the world they are very abundant, of large dimensions, and adorned with sparkling colours. ”

“ No doubt a larger knowledge of development, coupled with the advance of comparative anatomy, will ultimately bring about a better state of affairs. The Strepsiptera, with one family Stylopidae, are only provisionally included among the Coleoptera. These six series are fairly equal as regards extent. Though the Polymorpha includes the larger number of forms, yet a large part of them belong to four great families (Staphylinidae, Buprestidae, Elateridae, Malacodermidae) , which are easily recognisable, so that the number of unmanageable forms is not really great. ”

“ The Buprestes, as zealous as the Longicorns in the destruction of trees, whether sound or ailing, tell us the same tale as the Cerambyx- and Saperda-beetles. The Bronze Buprestis (B. ænea) is an inmate of the black poplar. Her larva gnaws the interior of the trunk. For the nymphosis it installs itself near the surface in a flattened, oval cell, which is prolonged at the back by the wandering-gallery, firmly packed with wormed wood, and in front by a short, slightly curved vestibule. A layer of wood not a twenty-fifth of an inch thick is left intact at the end of the vestibule. ”

Obs. This species comes perhaps too near to some of the darker varieties of B. variabilis, of the true appearance of which scarcely any idea can be formed from the figures of Donovan. Our insect bears a remarkable similarity to a Surinam Buprestis, with serrated elytra. ”

“ As for the Buprestis, he is in a state of inertia so profound that at first I really believe him to be dead. He recovers during the night; and next day I find him in possession of his usual activity. The ether experiment, which I took care to stop at the moment when it produced the desired effect, has not been fatal to him; but it has had much more serious consequences for him than for the Geotrupes. The insect more sensitive to the alarm due to concussion or to a fall of temperature is also the more sensitive to the action of ether. ”

“ The Buprestis has his legs symmetrically folded against his chest and belly; the Geotrupes has his outspread, stretched in disorder, rigid and as though attacked by catalepsy. You could not tell if they were dead or alive.
They are not dead. In a minute or two, the Geotrupes' tarsi twitch, the palpi quiver, the antennæ wave gently to and fro. Then the fore-legs move; and a quarter of an hour has not elapsed before the other legs are struggling. The activity of the insect made motionless by the concussion of a shock would reawaken in precisely the same fashion. ”

“ The exit-channel is nearly always bored completely; the window by which the insect escapes opens directly upon the outside world. At most, in a few rare instances, the grub leaves the Buprestis the trouble of piercing a leaf of wood so thin as to be translucent. But, if easy paths are necessary to the insect, protective ramparts are no less needed for the safety of the nymphosis; and the larva plugs the liberating channel with a fine paste of masticated wood, very different from the ordinary sawdust. ”

“ The cleanliness and freshness of the Buprestes whom she buries in her lair incline one to believe that she must seize these Beetles at the moment when they are leaving the wooden galleries in which their final metamorphosis has taken place. But what inconceivable instinct urges her, a creature that lives solely on the nectar of flowers, to procure, in the face of a thousand difficulties, animal food for carnivorous children which she will never see, and to take up her post on utterly dissimilar trees, which conceal deep down in their trunks the insects destined to become her prey? ”

“ The insect has already shown us this. The Giant Scarites does not stir for an hour, while the Smooth-skinned Scarites, a pigmy, wearies my persistence in turning him over; the large Cloudy Buprestis submits to my manoeuvres for a long period, whereas the Glittering Buprestis, a pigmy again, obstinately refuses to do so.
We will leave on one side, as insufficiently investigated, the influence of the bodily mass and remember only this fact, that it is possible, by a very simple artifice, to reduce a bird to a condition of apparent death. ”

“ The Buprestis, a lover of the burning sunshine, is affected by the cold bath in a different degree from the Scarites, who prowls about by night and spends his day in the basement. A fall of a few degrees in temperature takes the chilly insect by surprise and has no effect upon the one accustomed to the coolness underground. ”

“ Dufour supposed that these Buprestes were simply dead, and, “in order to explain this marvellous preservation of their flesh, which makes an insect that for several weeks has been motionless as a corpse a kind of game that does not become high but remain [156] as fresh as at the moment of capture during the greatest heat of summer, he presumed the use of a liquid antiseptic, acting in the same manner as the preparations used to preserve anatomical specimens. This liquid could only be the venom of the Hymenopteron inoculated into the victim’s body. ”

“ This sudden change in the system of road-making on behalf of the coming insect once more suggests for our meditation the eminent degree of foresight possessed by a bit of an intestine.
The cylindrical exit-way passes through the strata of wood along the shortest line, almost normally, after a slight bend which connects the vertical with the horizontal, a curve with a radius large enough to allow the stiff Buprestis to tack about without difficulty. It ends in a blind-alley, less than a twelfth of an inch from the surface of the wood. ”

“ We should be perplexed by the same question in respect of a multitude of insects, some of which remain motionless while others do not; and we could not possibly foresee what would happen from the genus of the subject, its form, or its way of living.
Buprestis tenebrionis, for example, exhibits a persistent inertia. Will it be the same, because of similarity of structure, with other members of the same group? Not at all. My chance finds provide me with the Brilliant Buprestis (B. rutilans, FAB.) , and the Nine-spotted Buprestis (Ptosima novemmaculata, FAB.) . The first resists all my attempts. ”

“ At the far end the industrious mother establishes the cradle of her progeny. Five cells, separate and independent of one another, are hollowed in the shape and nearly of the size of an olive; within they are solid and polished. Each can contain three Buprestids, the ordinary allowance for a larva. The Cerceris lays an egg amid the three victims, and then stops up the gallery with [46] earth, so that when once the provisions for the brood are laid in, the cells have no communication with the outside. ”

“ It would be of the highest importance to bring forward such facts if they exist, as they would tell us whether the suggestions of instinct are absolute and immutable, or if they vary, and within what limits. It is true that in the cell of a Cerceris are buried most varied species of Buprestids or of the Weevil group, which shows that she has a great latitude of choice ”

“ It is true that many allow themselves a more varied bill of fare, but only within the limits of one entomological group: thus the Weevil and Buprestis hunters prey upon any species proportioned to their strength. Were the Hairy Ammophila to make a change in her diet, that would be her case too. ”

“ Out of more than 400 beetles dug up, there was not one which did not belong to the old [45] genus Buprestis! Our Hymenopteron had not committed the smallest error. How much there is to learn from this intelligent industry in so small an insect! What value Latreille would have attached to the vote of this Cerceris in favour of the natural system!1
Let us pass on to the various contrivances of the Cerceris in making and provisioning her nest. I have already said that she chooses ground whose surface is beaten, compact, and solid. ”

“ Such is the conclusion arrived at by Léon Dufour before this incomprehensible marvel of the dead Buprestis untouched by corruption. An antiseptic fluid, incomparably superior to anything that human science could produce, would explain the mystery. He, the Master, skilful of the skilful, thoroughly used to most delicate anatomy; he who with magnifying glass and scalpel has scrutinised the whole circuit of entomology, leaving no corner unexplored ”

“ The buried Buprestes, like those whom I have seized in the grasp of their kidnappers, are always deprived of any sign of life; in a word, they are decidedly dead. I was surprised to remark that, no matter when these corpses were dug up, they not only preserved all their freshness of colouring, but their legs, antennæ, palpi, and the membranes uniting the various parts of the body remained perfectly supple and flexible. ”

“ He has remarked that the ruminants constitute baits for flies; therefore he never leaves these animals, hops about on their backs and delivers them from annoying parasites; the buffaloes, who recognise this service, allow the bird to wander quietly over their hide. The Buphaga, who gives himself up entirely to this kind of chase, is often called the Beef-eater. He is only found in the society of flocks, of camels, buffaloes, or oxen. He settles on the back, legs, and snouts of these living baits. They remain passive even when he opens the skin in order to draw out the flies’ larva ”

“ She who fed on Weevils in her youth puts Weevils and naught else in her larva’s cell; she who was [373] supplied with Buprestis-beetles persists in the fare which she has adopted and serves her larva with Buprestis-beetles. One Sphex must have Crickets; a second, Grasshoppers; a third, Locusts. Nothing is accepted but these particular dishes. The Bembex who hunts Gad-flies revels in them and refuses to do without them, whereas Stizus ruficornis, who fills the larder with Praying Mantes, scorns any other game. And so with the rest. They have each their own taste. ”

“ For the harsh work of its two gouges, or curved chisels, the larva of the Capricorn concentrates its muscular strength in the front of its body, which swells into a pestle-head. The Buprestis-grubs, those other industrious carpenters, adopt a similar form; they even exaggerate their pestle. The part that toils and carves hard wood requires a robust structure; the rest of the body, which has but to follow after, continues slim. The essential thing is that the implement of the jaws should possess a solid support and a powerful motor. ”

“ During the greater part of the year the bustards are far too wary to be obtained by the farm-hands and shepherds who see them every day; and so accustomed are the peasants to the sight of these noble birds that little or no notice is taken of them. Their haunts and habits not being studied, their pursuit is regarded as impracticable. There is, however, one period of the year when the Great Bustard falls an easy prey to the clumsiest of gunners. ”
