list of animals that produce silk
silkworms, the caterpillars and pupae of the moth "bombyx mori", have been reared to produce silk in china from the neolithic yangshao period onwards, c. 5000 bc. production spread to india by 140 ad. the caterpillars are fed on mulberry leaves. the cocoon, produced after the fourth moult, is covered with a continuous filament of the silk protein, fibroin, gummed together with sericin. in the traditional process, the gum is removed by soaking in hot water, and the silk is then unwound from the cocoon and reeled. filaments are spun together to make silk thread. commerce in silk between china and countries to its west began in ancient times, with silk known from an egyptian mummy of 1070 bc, and later to the ancient greeks and romans. the silk road leading west from china was opened in the second century ad, helping to drive trade in silk and other goods.
