Plaster Bagworm

Found indoors on walls of houses, particularly in humid climates, as well as on tree trunks or in debris where silk can be found.

The larvae feed on spider webs, wool, human hair, shed skin cells, and other silk-based materials.

The larva constructs a protective spindle-shaped case from silk and covered with sand, soil, and insect droppings. It can crawl with its case and reach out from either end to feed.

Potentially a minor household pest that can damage woolen fabrics or rugs, but generally harmless to humans. They are beneficial for cleaning up spider webs and organic debris.
