Definition of silkworm moth in English English dictionary: Any of the moths, chiefly of the family Bombycidae, whose larvae produce silk cocoons. Any moth in the genus Bombyx (family Bombycidae). The Chinese silkworm (B. mori) has been used in commercial silk production for centuries. The adult, which has a wingspan of about 2 in. (50 mm) and a thick, hairy body, lives only two or three days. The female lays 300-500 eggs. The pale, naked larvae are fed mulberry leaves until pupation begins, when they are about 3 in. (75 mm) long. They spin a cocoon of one continuous white or yellow silken thread, about 1,000 yards (900 m) long. The pupa is killed with hot air or steam to preserve the thread intact. See also saturniid moth
domestic silkworm moth: stocky creamy-white Asiatic moth found almost entirely under human care; the source of most of the silk of commerce
