The male triumphs again, and more frequently, among coleoptera. The nasicom scarab, so called most aptly because he carries on his head a long back-bending arched horn, has all his chest solidly armoured; the female has neither horn nor cuirass. Everyone knows the flying-stag or lucane (stag-beetle, bull-fly), enormous coleoptera which flies through the summer evening buzzing like a top. He is feared for the bold appearance of his long mandibles which branch like stag's horns and which the uninstructed take for dangerous pincers. He is the male, his war-gear pure ornament, as he lives inoffensively by sucking tree-sap. The much smaller females are devoid of warlike apparatus, they are very few in number, and it is in the excitement of searching for them that the male, whose life is short and who knows it, whirls like a maniac, and bangs himself into our trembling ears. Here again one divines animals who have changed their habits more quickly than their organs. The old pirate has kept his daggers and axes, but abandoned, no one knows why, to vegetarian diet, he has lost all power to use them, he is merely a stage-super. But maybe this gear impresses the female? She cedes more willingly to this hector who gives her the illusion of strength, that is of the male's beauty. The glow-worm is a real worm, but a larva rather than a definitive animal. The male of this female is a perfect insect, provided with wings which he uses to seek in the darkness the female who shines more brightly as she more desires to be looked at and mounted. There is a kind of lampyre of which both sexes are equally phosphorescent, one in the air, the male, the other on the ground where she awaits him. After coupling they fade as lamps when extinguished. This luminosity is, evidently, of an interest purely sexual. When the female sees the small flying star descend toward her, she gathers her wits, and prepares for hypocrite defence common to all her sex, she plays the belle and the bashful, exults in fear, trembles in joy. The fading light is symbolic of the destiny of nearly all insects, and of many animals also; coupling accomplished, their reason for being disappears and life vanishes from them.
