Case-bearing Clothes Moth (Larva)

Found indoors in darkened areas like closets, attics, and under furniture where natural fibers are stored.

Larvae feed on natural animal keratins found in wool, silk, fur, feathers, and upholstered furniture.

The larva constructs a portable flattened case made of silk and debris (like the fibers shown in the image) which it drags along while feeding and pupating.

They are a significant domestic pest that can cause extensive damage to expensive clothing, rugs, and heirlooms; they provide no significant benefit in a domestic environment.
