A silk moth that feeds on mulberry leaves and is the source of fine, natural silk. ‘Moms’ is the Latin word for ‘mulberry’. Hence it is called Bombyx mori because it is reared on mulberry leaves. In India Bombyx mori are reared throughout the year. It is a domesticated silkworm because it can be reared indoors. It was domesticated almost 4000 years ago and thus the Bombyx mori silk moth cannot fly (unlike wild silk moths) ever since. See Part Three: Sericulture.
