Bombyx second Hybrid : ウィキペディア英語版 | Bombyx second Hybrid
Bombyx second Hybrid is a cross between a male ''Bombyx mori'', and a female ''Bombyx mandarina''. Since male Bombyx Mori cannot fly to the female to mate anymore, they are 100% dependent on humans to reproduce. They produce Silkworms like all species in Bobmyx, except they are brownish at the top and grayish at the end. They produce silk, and give out black droppings. The domesticated silkworm (''B. mori'') was domesticated from wild silkworm (''B. mandarina'') more than 5,000 years ago.
