bagworm moth (redirected from Psychidae)

bagworm moth

Any insect of the moth family Psychidae, found worldwide, named for the baglike cases the larvae (see larva) carry with them. The bag, which ranges in size from 0.25 to 6 in. (6–150 mm), is constructed from silk and bits of leaves, twigs, and other debris. The strong-bodied male has broad, fringed wings with a wingspread averaging 1 in. (25 mm). The wormlike female lacks wings. Bagworm larvae often damage trees, especially evergreens.
