As larvæ, the young burying beetles look like worms, and have six short legs. No. 4 shows them in the intermediate stage, when they have retired into a clay cell, or cocoon, and are undergoing their transformation into the perfect insect. We are here supposed to have removed the soil on one side so as to give a view into the concreted earthen chambers where the pupæ are changing into full-grown beetles. You can see the much longer legs of the adult insect beginning to develop, while the head assumes slowly its later form. The grubs remain in the cocoon through the winter, and emerge in spring as winged beetles, when they fly away with their brilliant wing-cases raised, in search of congenial mates and more dead field-mice. The best places to look for all these beetles are the "keeper's trees," on which game-keepers hang up the jays and weasels they shoot, to encourage the others. If you tap one such dead weasel you will generally find it is simply swarming with insect life. [Illustration: 4.--NO MORE LEFT! THE GRUBS IN THEIR COCOONS TURNING INTO BEETLES.] Yet, strange to say, even the insect undertakers themselves are not without their ideas of beauty and their musical perceptions. The orange bands of our commonest English kind have been developed as attractions for their admiring mates; and the male beetles have also a musical instrument of their own in the shape of a peculiar rasp-like ring on the body, which they can rub against the wing-cases, and so produce a much-appreciated chirping. Such instrumental music is always employed, like the song of birds, as a charm to heighten the attractiveness of the suitor: and male burying beetles may be heard on the evenings of sunny days competing with one another in musical contests. Indeed, it often happens that animals which seem to us disgusting or unclean display among themselves much æsthetic taste, and are gifted with more sense of beauty or love of music than many other forms where our human eyes would be more inclined to look for the presence of these higher endowments. I may add that if the beetles left the bodies in which they laid their eggs to lie above ground, the bodies would dry up, and the eggs would run much greater risks. By burying the dead animal, they provide their young with food and shelter together, and so display considerable intelligence.
