Bagworm (Bagworm Moth Caterpillar)

Deciduous and coniferous trees, shrubs, orchards, and urban gardens across North America.

Herbivorous; feeds on foliage, flowers, and tender bark of host plants, including cherries, junipers, arborvitae, and pines.

Larvae construct portable protective cases out of silk and host plant debris (twigs, leaf bits). They carry these bags with them while feeding and pupate inside them.

Risks: Can cause severe defoliation and stress to host trees if populations are large. Benefits: Provides food for birds, parasitic wasps, and other natural predators.
