They produce larvae called silkworms, like all species of Bombyx.

Generally, they look like a normal Bombyx moth, but a bit darker.

Because Bombyx mori males lost their ability to fly, their females are much more likely to mate with a male Bombyx mandarina.

B. mori is a domesticated version of the wild B. mandarina.
