Case-bearing clothes moth (larva)

Domestic environments, specifically closets, rugs, and storage areas containing natural fibers.

Natural keratinous materials including wool, fur, feathers, hair, and silk.

The larva constructs a portable protective case from silk and fibers from the material it is eating. It stays inside this case as it feeds and eventually pupates.

These insects are significant pests that cause damage to clothing, upholstery, and carpets; they offer no direct benefits to the indoor human ecosystem.
