Evergreen Bagworm

Be Alert to Bagworms

Bagworms (Thyridopteryx ephemeraeformis, family Psychidae) are moth larvae (caterpillars) that develop within silk bags festooned with pieces of their host plants. As the caterpillars mature, they begin weaving more host plant debris into the silk, which provides structural stability as well as camouflage.
