Plaster Bagworm (Case-bearing Clothes Moth larva)

Commonly found inside households, particularly on walls in humid climates like the southeastern United States.

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

The larva constructs a protective silk case covered in sand, dust, and lint; it can turn around inside the case to feed from either end.

Primarily a household nuisance; they can cause minor damage to natural fabrics like wool or silk and are considered a pest.
