Case-bearing clothes moth larva

Indoor environments, particularly in dark, undisturbed areas like closets, under furniture, or rugs.

Keratin-rich animal fibers including wool, silk, fur, feathers, and hair; occasionally feeds on stored grains or spices.

Larvae construct a portable protective case from silk and fibers from the material they are eating; they carry this case as they move and eventually pupate inside it.

Risk: Serious pest that damages high-value textiles, clothing, and carpets. Benefit: Minor role in ecosystems by breaking down natural animal debris in the wild, but predominantly viewed as a household pest.
