Household Casebearer / Plaster Bagworm

Found within indoor environments, particularly on walls or under furniture in humid climates.

Larvae feed on spider webs, wool, hair, and organic detritus.

The larva constructs a protective silk case covered in sand, dust, and debris. It can protrude from either end of the flattened case to move or feed.

Generally considered a minor household pest. Risks include potential damage to wool clothing or rugs, but they are harmless to humans and do not bite or sting.
