Bagworm Moth Larva

Widely distributed in trees and shrubs, including evergreens like juniper and arborvitae, as well as deciduous trees.

Larvae are generalist feeders that consume foliage from over 128 different plant species, often causing significant defoliation.

Larvae construct a protective silk case covered with bits of leaves and twigs from their host plant. They carry this case with them as they feed and eventually pupate inside it.

They are considered a significant landscape pest as they can defoliate and kill host trees if populations are high. They benefit the ecosystem by serving as a food source for birds and parasitic wasps.
