The caterpillars of many moths and of a few butterflies produce silk,
but certain of those belonging to the family Bombycidae, or true silk
spinners, particularly Bombyx (Sericaria) mori, or the mulberry
silkworm, yield the most and the best silk. The races of Bombyx mori
today are the result of domestication and artificial rearing, and he
wild type is uncertain, though most authorities assign the foot of the
Himalaya as the cradle of the mulberry silkworm. It has been
industrially cultivated in China from time immemorial, and in Europe
since the sixth century.
