But he wore a gaudy fabric made of one. The moths and giant butterflies were harmless to men. Burl's fellow tribesmen sometimes came upon a cocoon when it was just about to open, and if they dared they waited timorously beside it until the creature inside broke through its sleeping-shell and came out into the light. Then, before it gathered energy from the air and before its wings swelled to strength and firmness, the tribesmen fell upon it. They tore the delicate wings from its body and the still-flaccid limbs from their places. And when it lay helpless before them they fled away to feast on its juicy meat-filled limbs. They dared not linger, of course. They left their prey helpless--staring strangely at the world about it through its many-faceted eyes--before the scavengers came to contest its ownership. If nothing more deadly appeared, surely the ants would come. Some of them were only inches long, but others were the size of fox-terriers. All of them had to be avoided by men. They would carry the moth-carcass away to their underground cities, triumphantly, in shreds and morsels. But most of the insect world was neither so helpless nor so unthreatening. Burl knew of wasps almost the length of his own body, with stings that were instantly fatal. To every species of wasp, however, some other insect is predestined prey. Wasps need not be dreaded too much. And bees were similarly aloof. They were hard put to it for existence, those bees. Since few flowers bloomed, they were reduced to expedients that once were considered signs of degeneracy in their race: bubbling yeasts and fouler things, or occasionally the nectarless blooms of the rank giant cabbages. Burl knew the bees. They droned overhead, nearly as large as he was, their bulging eyes gazing at him and everything else in abstracted preoccupation. There were crickets, and beetles, and spiders.... Burl knew spiders! His grandfather had been the prey of a hunting tarantula which had leaped with incredible ferocity from its tunnel in the ground. A vertical pit, a yard in diameter, went down for twenty feet. At the bottom of the lair the monster waited for the tiny sounds that would warn him of prey approaching his hiding-place. Burl's grandfather had been careless. The terrible shrieks he uttered as he was seized still lingered vaguely in Burl's mind. And he had seen, too, the webs of another species of spider--inch-thick cables of dirty silk--and watched from a safe distance as the misshapen monster sucked the juices from a three-foot cricket its trap had caught. He remembered the stripes of yellow and black and silver that crossed upon its abdomen. He had been fascinated and horrified by the blind struggling of the cricket, tangled in hopeless coils of gummy cord, before the spider began its feast.
