The wren slipped away through the masses of fragrant Davilla blossoms, but his songs remained and are with me to this moment. And now I leaned back, lost my balance, and grasping the old stump for support, loosened a big piece of soft, mealy wood. In the hollow beneath, I saw a rainbow in the heart of the dead tree.
This rainbow was caused by a bug, and when we stop to think of it, this shows how little there is in a name. For when we say bug, or for that matter bogy or bugbear, we are garbling the sound which our very, very forefathers uttered when they saw a specter or hobgoblin. They said it _bugge_ or even _bwg_, but then they were more afraid of specters in those days than we, who imprison will-o'-the-wisps in Very lights, and rub fox-fire on our watch faces. At any rate here was a bug who seemed to ill-deserve his name, although if the Niblelungs could fashion the Rheingold, why could not a bug conceive a rainbow?
Whenever a human, and especially a house-human thinks of bugs, she thinks unpleasantly and in superlatives. And it chances that evolution, or natural selection, or life's mechanism, or fate or a creator, has wrought them into form and function also in superlatives. Cicadas are supreme in longevity and noise. One of our northern species sucks in silent darkness for seventeen years, and then, for a single summer, breaks all American long-distance records for insect voices. To another group, known as Fulgorids, gigantic heads and streamers of wax have been allotted. Those possessing the former rejoice in the name of Lantern Flies, but they are at present unfaithful vestal bugs, though it is extremely doubtful if their wicks were ever trimmed or lighted. To see a big wax bug flying with trailing ribbons slowly from tree to tree in the jungle is to recall the streaming trains of a flock of peacocks on the wing.
The membracids must of all deserve the name of "bugges" for no elf or hobgoblin was ever more bizarre. Their legs and heads and bodies are small and aphid-like, but aloft there spring minarets and handles and towers and thorns and groups of hairy balls, out of all reason and sense. Only Stegosaurus and Triceratops bear comparison. Another group of five-sided bugs are the skunks and civet-cats among insects, guarding themselves from danger by an aura of obnoxious scent.
