Common Name: Bagworm
Order: Lepidoptera Family: Psychidae Pest Status: The bagworm can become a serious pest of evergreen trees and shrubs, occasionally of broad leaf trees. Appearance: Bagworms themselves are seldom seen due to the protective, cone-shaped bag that encloses the insect. The bag is approximately 1 1/2-inches long and is composed of silk, leaves, and twigs. Mature male larvae, however, do eventually leave the bag for a short time. They range in color from brown to tan, and are usually mottled with black markings. Life Cycle: Adult moths are active in late summer and early fall. The females remain within the bags to lay the overwintering eggs. The eggs do not hatch until June and the larvae immediately begin to form the silken bag where they remain until August when pupation occurs. Where to Collect: Larvae attach their very conspicuous bags to branches of trees. |
