Case-bearing clothes moth (larva)

Indoor environments, specifically closets, wardrobes, and upholstery where natural fibers are stored.

Keratin-based materials including wool, fur, feathers, hair, and silk, as well as dead insects and plant debris.

The larva constructs a protective silken case incorporating fibers from its food source, which it carries while feeding and eventually uses for pupation.

Pests that cause significant damage to clothing, rugs, and textile collections; no direct health risk to humans but economically destructive.
