Bagworm Moth (Larva/Case)

Natural Habitat

Commonly found on coniferous and deciduous trees and shrubs, including cedar, juniper, and maple.

Diet & Feeding

Larvae feed on the leaves and needles of host plants, often causing significant defoliation.

Behavior Patterns

Larvae construct a protective silk case covered with bits of plant material. They carry this case as they move and feed, eventually pupating inside it.

Risks & Benefits

Considered a landscape pest because they can kill host trees through heavy defoliation; however, they provide food for birds and predatory insects.
