Case-bearing clothes moth (larva)

Indoor environments, particularly in closets, drawers, or areas with stored fabrics, woolens, and rugs.

Keratin-rich materials including wool, fur, silk, feathers, and felt. They can also feed on lint, hair, and spices.

The larva builds a portable silken case incorporating fibers from its environment, which it stays inside while feeding. They are photophobic (avoid light) and complete their life cycle entirely indoors.

Significant risk as a domestic pest; they cause permanent damage to clothing, upholstery, and expensive tapestries. They offer no notable benefits to the home ecosystem.
