See this bug in the Encyclopedia

Natural Habitat

Fully domesticated and primarily found in silk farms; they no longer exist in the wild. Larvae are raised on trays.

Diet & Feeding

Larvae (silkworms) feed exclusively on the leaves of white mulberry trees. Adult moths do not eat.

Behavior Patterns

Larvae spin silk cocoons to protect themselves during pupation. After 2-3 weeks, moths emerge. They are flightless and live only a few days to mate and lay eggs.

Risks & Benefits

Benefits: The primary source of commercial silk, a major global textile. Risks: No risk to humans; they are economically valuable but entirely dependent on human care.
