Bombycidae

Definition

A family of medium-sized moths in the order Lepidoptera, commonly called silkworm moths, characterized by stout bodies, reduced mouthparts in adults, and larvae that spin large, commercially valuable silk cocoons. The family includes the domesticated silkworm moth and related wild species native to Asia.

Etymology

From Bombyx (type genus, from Greek bombux 'silkworm, silk') + -idae (family suffix)

Example

Bombyx mori, the domestic silk moth, is the most economically important member of Bombycidae, having been domesticated for over 5,000 years for sericulture; its wild ancestor, Bombyx mandarina, occurs in mulberry forests across East Asia.

Usage Notes

Bombycidae has undergone significant taxonomic revision; many genera formerly placed here (including the giant silk moths) have been moved to Saturniidae and other families. Modern circumscriptions are narrower, focusing on the Bombyx lineage and close relatives. The family is nested within Bombycoidea, though exact composition varies by phylogenetic study. Not to be confused with the broader historical usage or with Saturniidae (giant silk moths).
