Let us recapitulate the unheard-of series of events, the inextricable complication of circumstances, which are required to condition the lowly life of a Sitaris. In the first place, this microscopic creature must be provided with talons, or how could it adhere to the fleece of the Anthophora, on which it must live as parasite for a certain length of time? Then again, it must transfer itself from the male to the female bee in the course of its travels abroad, or its destiny would be cut short. Again, it must not miss the opportunity of embarking itself upon the egg just at the propitious moment. Then the volume of this egg must be so calculated as to represent an allowance of food exactly proportioned to the duration of the first phase of its metamorphosis. Moreover, the quantity of honey accumulated by the bee must suffice for the whole of the remaining cycle of its larval existence. Let a single link of the chain be broken, and the entire species of the Sitaris is no longer possible. If every species has its law; if the Geotrupes remain faithful to filth, although experience shows that they can accommodate themselves equally well to the putrefaction of decayed leaves; if the predatory species--the Cerceris, the Sphex, the Ammophila--resort only to one species of quarry to nourish their larvae, although these same larvae accept all indifferently, it is on account of those superior economic laws and secret alliances the profound reasons for which as a rule escape us or are beyond the scope of our theories. For all things are produced and interlocked by the eternal necessity; link engages in link, and life is only a plexus of solitary forces allied among themselves by their very nature, the condition of which is harmony. And the whole system of living creatures appears to us, through the work of the great naturalist, as an immense organism, a sort of vast physiological apparatus, of which all the parts are mutually interdependent, and as narrowly controlled as all the cells of the human body. Fabre goes on to present us with other facts, which at a first glance appear highly immoral; I am referring to certain phases of sexual love among the lower animals, and his ghoulish revelations concerning the horrible bridals of the Arachnoids, the Millepoda, and the Locustidae. The Decticus surrenders only to a single exploit of love; a victim of its "strange genesics"; utterly exhausted by the first embrace, empty, drained, extenuated, motionless in all its members, utterly worn out, it quickly succumbs, a mere broken simulacrum, like the miserable lover of a monstrous succubus who "loves him enough to devour him." (11/3.) The female scorpion devours the male; "all is gone but the tail!" The female Spider delights in the flesh of her lover. The cricket also devours a small portion of her "debonair" admirer. The Ephippigera "excavates the stomach of her companion and eats him."
