The domesticated silkworm derives from Chinese rather than Japanese or Korean stock. Silkworms were unlikely to have been domestically bred before the Neolithic age. Before then, the tools to manufacture quantities of silk thread had not been developed. The domesticated "B. mori"
Bombyx hybrid have to be kept in the same container. Since "Bombyx" hybrids are much more common than the other variation more is known about them. The domesticated silkworm ("B. mori") was domesticated from wild silkworm ("B. mandarina") more than 5,000 years ago. Bombyx hybrid The "Bombyx" hybrid is a hybrid between a female "Bombyx mori" moth and a male "Bombyx mandarina" moth. They produce silkworm larvae like all species of "Bombyx". The larvae look a lot like the other variations. They are brown in the first half and gray at the bottom half, but they get larger black spots than other
