(Allorhina nitida, Linn.)
In looking at these two strange beings (this picture and the next), we cannot feel confident that science has gone very far in giving us the reasons for the things we see. They seem no more alike than fish and tortoise or bird and quadruped and yet, before our very eyes, in one brief year, the one turns into the other.
This beetle dies, and leaves behind a hundred little cells, parts of its own body and the body of its mate. These paired cells, the fertilized eggs, grow rapidly into the form of the clumsy, helpless grub which feeds upon the leaves, only to break up and form themselves again into this armor-plated creature of the beetle world.
There must be something as radically wrong with our individualistic ideas of today as there was with the conception of a flat world which prevailed before the time of Columbus. Perhaps if we stop trying to think of these manifestations of beetle life as individuals and think of them as parts of one great organism scattered over the surface of the earth, these striking differences will seem no stranger to us than do the differences in the various stages of a flower’s life. The beetle forms inside the grub and the tulip flower bud forms inside the bulb. If tulip flowers could fly, we should then have the strange spectacle of the opening of the scale-covered tulip bulb and the coming forth of the gorgeous colored flower which sailed away to shed its seeds in someone else’s garden. I think that this is the way we must look at it if we would get a clear idea of this strangest of phenomena,—metamorphosis.
THE JUNE BEETLE LARVA
(Allorhina nitida, Linn.)
How is it possible that this fat creature, with eye-like breathing pores along its body, whose legs are worthless, and which is so helpless that it has to turn over on its back to wriggle over the ground, can change into the emerald-green June beetle which wings its way like an aerodrome across the meadow? This is the apparent miracle of metamorphosis which it has well-nigh baffled the intellect of man to explain.
