Why beetles as large as elephants never came into existence on this planet, or have they developed on some other of the countless worlds of space, are questions too hard for us to answer.
This wonderfully protected creature with long horn-like antennæ and hippopotamus-like jaws is a relative of the largest of the beetles, those which live in the great forests along the Amazon or in the tropical jungles of the Fijian Islands, and whose grubs are good to eat. Some years ago, in a clearing in a New Zealand forest, a Maori dug out several handfuls of the white wriggling creatures for me and a settler’s wife fried them with butter over the fire in her kitchen stove, and I can testify that they were as crisp and delicate as fried oysters.
Like the other giant creatures of the forest, these Prionids, as they are called, are growing rarer with the destruction of the forest trees on which they live, and some day their skeletons in museum cases may be all that remain of them.
These long-horned wood borers do not themselves bore into the wood; how could they with their long antennæ? It is their other selves, their grubs, that live deep in the solid heart wood of some oak or hickory tree. There is something strange in their solitary hermit-cell life. Think of living for two years or more in a narrow hole which shuts you in on all sides and having for a steady diet the walls of your cell to feed upon. Prisoners have burrowed under prison stockades to escape, but these larvæ deliberately leave the outer, softer sapwood in which they hatch, and start for the interior of the trunk, packing behind them with sawdust and excrement the tunnel which they eat out.
The fact that the grubs of some species of these Prionids choose to live in the roots and trunks of trees which we choose to cultivate makes them our enemies, and every good orchardist knows that the only way to stop them is to dig them out or stab them with a wire run through them in their burrows.
This fellow bit savagely at a pencil, and when he finally caught hold, I lifted him up as one does a bull dog, and he hung there almost as long.
