Is this all? No; we are far from having made the tour of this miraculous and incommensurable kingdom through which this admirable master leads us, and I should never be done were I to attempt to exhaust all the spectacles which he offers us. Let us descend yet another step, among creatures yet smaller and humbler. We shall find tendencies, impulses, preferences, efforts, intentions, "Machiavellic ruses and unheard-of stratagems." Certain miserable black mites, living specks, the larvae of a beetle, one of the Meloidae, the Sitaris, are parasites of the solitary bee, the Anthophora. They wait patiently all the winter at the entrance of her tunnel, on the slope of a sunny bank, for the springtime emergence of the young bees, as yet imprisoned in their cells of clay. A male Anthophora, hatched a little earlier than the females, appears in the entrance of the tunnel; these mites, which are armed with robust talons, rouse themselves, hasten to and fro, hook themselves to his fleece, and accompany him in all his peregrinations; but they quickly recognize their error; for these animated specks are well aware that the males, occupied all day long in scouring the country and pillaging the flowers, live exclusively out of doors, and would in no wise serve their end. But the moment comes when the Anthophora pays court to the fair sex, and the imperceptible creature immediately profits by the amorous encounter to change its winged courser. "These pigmies therefore have a memory, an experience of facts" (and how one is tempted to add, a glimmering of intelligence!). Grappled now to the female bee, the grub of the Sitaris "conceals itself, and allows itself to be carried by her" to the end of the gallery in which she is now contriving her cradle, "watches the precise moment when the egg is laid, installs itself upon it, and allows itself to fall therewith upon the surface of the honey, in order to substitute itself for the future offspring of the Anthophora, and possess itself of house and victuals." (8/18.) Another "little gelatinous speck," "a shadow of a creature," the larva of a Chalcidian, the Leucopsis, one of the parasites of the Mason-bee, knows that in the cell of the mason there is food for one only. Scarcely has it entered the tiny dwelling but we see this "nameless shape" for several days "anxiously wandering; it visits the top and bottom, the back, the front, the sides"; it makes the tour of its domain; "it searches in the darkness, palpitating, seemingly with an object in view." What does this "animated globule" want? why is this atom so excited? It is searching to discover if there is not in some corner hitherto unexplored another larva, a rival, that it may exterminate it! (8/19.) What then intrinsically is instinct? And what intrinsically is intelligence?
