But can our Libellulæ be carnivorous? Most undoubtedly. To convince yourself of it, you have but to glance at their mouth, which is wholly unlike a butterfly's. What an arsenal of weapons adapted for seizing and crushing a victim! How strong are those saw-toothed scaly mandibles! How strong their auxiliaries, the jaws, which terminate in that dentated spring projection, furnished internally with ciliæ! Surely, such instruments testify to their ferocious instincts, and should induce our French neighbours to deny them the graceful name of "les demoiselles." What a libel on tender woman,--on man's "ministering angel!" Do but observe them. They do not rest upon the blossom to extract its nectared sweets; in truth, they could not do so, for they are not furnished with a proboscis. Warlike as the Amazons,--the only portion of the female sex they can justly be said to resemble,--they hover in the air to pounce, like vultures, upon whatever insects may come within their reach; they quickly transfix, and as quickly devour them. If they love to fly about the pools, the marshes, and the streams, it is because they are sure of prey in these localities. And, in fact, they there encounter and devour an innumerable quantity of flies, moths, gnats, and the like. * * * * * But there is another reason why the Dragon-flies, obeying the secret impulse of nature, resort to the haunts we have been describing. They were their cradles or nurseries, and they become, in due time, the scenes of their espousals. * * * * * Before speaking of the singular metamorphosis they afterwards accomplish, we must touch lightly on the subject of the mode of reproduction of our brilliant _demoiselles_. It is laid down as a law that, in the insect world, the males are invariably smaller or weaker than the females. Yet this law does not hold good with reference to the Libellulæ, whose males are, on the contrary, larger and stronger than their females. Man may lay down laws, and extort obedience to them, within his own domain; but nature laughs at human rules, and gives up her secrets only to the free thought, unshackled by the fetters of authority. But why is the male Dragon-fly stronger than the female? Because the former must make the first advances, and carry off his aërial companion to celebrate their bridal. For this purpose, he holds her tightly by the neck, and continues to fly in this way for some few minutes. At length, he perches himself on the branch of a willow, or the leaf of an aquatic plant, along with his companion. The eggs laid by the female are oblong in shape, and sometimes united together in clusters: the female deposits them in the water, or on some water-floated leaf plant, shortly after their fecundation.
