Household Casebearer moth

Typically found inside houses and buildings, especially in dark, undisturbed areas like closets or under furniture.

As larvae, they feed on spider webs, wool, human hair, fur, and silk.

The larva lives in a flat, spindle-shaped case made of silk and covered with sand, dust, and other debris. It can pull its head and legs into the case for protection.

Generally considered a pest as they can damage clothing and other natural fabrics, but they do not pose a direct health risk to humans.
