Household Casebearer (Plaster Bagworm)

Indoor environments, particularly on walls in humid climates, closets, and under furniture.

Larvae feed on spider webs, wool, hair, and silk, as well as dead insects.

The larva constructs a protective silk case flattened like a pumpkin seed, camouflaged with sand, dust, and lint. It can poke its head out from either end to move or feed.

Harmless to humans but considered a household pest as they can damage natural fiber clothing, rugs, and fabrics.
