Case-bearing clothes moth larva

Worldwide distribution; typically found indoors in dark, undisturbed areas like closets, under furniture, or rugs.

Keratin-rich animal fibers including wool, silk, fur, feathers, and lint; also known to ingest synthetic fibers blended with natural ones.

Larvae construct a portable silken case (often camouflaged with debris or food fibers) which they carry as they move and feed. They pupate within this case. Adults are small, buff-colored moths that prefer crawling to flying and do not feed.

Risks include damage to personal property such as clothing, rugs, and upholstery. They have no significant benefits to human environments and are considered household pests.
