Bagworm (Larva)

Found on various host plants, especially evergreens like arborvitae, cedar, juniper, and spruce, as well as deciduous trees.

Folivore; the larvae feed on the foliage of host trees and shrubs, often causing significant defoliation.

Larvae construct a spindle-shaped silk bag camouflaged with bits of foliage and bark. They carry this case as they feed and eventually pupate inside it. Females are wingless and remain in the bag their entire lives.

Risks: Can be a serious ornamental pest, causing severe defoliation that may eventually kill trees. Benefits: They serve as a food source for some birds and parasitic wasps that help control their population.
