The caterpillars were studying moral invisibility in a hundred different ways, for insect life is the most highly specialized of all. It was the lobster-moth-to-be that spoke first. He bent his head backwards until it touched his tail, folded the knee-joints of his skinny legs, and began—
“It is all bluff,” said he, “caterpillars are past-masters of bluff. Look at the hawkmoths, fat, flabby, bloated things, with curly tails. Most of them fling their heads back, arch their necks, and play at being snakes. Some grow eyes upon them, not real eyes, but markings which serve as such, enough to scare the average chuckle-headed bird. Sometimes they trust to vein-markings on their bodies, which turn them into casual misshapen leaves. Sometimes they liken themselves to twigs—”
“That is what we do,” cried the loopers. Each branch of the oak had its loopers, feeding cheerfully, transforming themselves to twigs, and shamming death in quick succession.
not real eyes but markings which serve as such.
“Sometimes,” continued the lobster-moth-to-be, “they are, like myself, really worth eating. Then, mere vulgar imitation bluff is of little avail. To be a withered leaf is my first line of defence; if the ichneumon buzzes nearer, I shift my ground and become a spider. I am the only caterpillar in the country with spider-legs; when they are stretched to their full length and quivering, they are worse to look at than the real thing. Should even this fail me, I show the imitation scar on my fourth body-ring. That usually clinches the matter. The ichneumon fondly imagines that I am already occupied. So, if I am lucky, I turn at length to dingy pupa, and thus preserve my race.”
“Will you hear an amphibian?” said the toad. He came from the centre of a grass-tuft, and spoke with solemn deliberation. “Not one of you is more persecuted than I. From time immemorial I have been the loadstone of credulity, and—I am altogether defenceless. I am never worth eating, for the shock of capture opens every pore on my skin, drenching me with what the poets class as venom. So I am usually thrown aside with a broken back. For centuries I was thought to have a jewel in my head. How many of my hapless ancestors were tortured for that jewel! With the toad’s death, the jewel was believed to vanish. How many have been ‘larned to be a toad’ by baffled, disappointed rustics! That is what puts the sad expression in my eye. How have I survived it all? By dogged perseverance. I lay so many eggs that one at least must survive. Thus is the balance of the race preserved. I myself was one of five hundred, the only one that reached maturity. Yet all were in the same long ribbon coil. The swan that gulped the coil, gulped all but me. I dropped into the brook alone, and there I quietly passed through my novitiate, egg to tadpole, tadpole to toadling, toadling to toad. When my tail was absorbed into my body, I sought a land-retreat. There I have spent my time for twenty years. None of you know it, and none ever will. I leave it only at twilight, and, as you pass, I shield my face with my fore feet. Froggin is much the same; nothing but his prolific quality saves him.”
