Clothing Moth Casemaking Larva (likely Plaster Bagworm or similar Case-bearing moth)

Typically found indoors in humid climates, often in closets, on wool clothing, carpets, or adhering to plaster walls and dusty corners.

Feeds on natural fibers (wool, silk, fur), spider webs, shed insect skins, human hair, and lint found in dust.

The larva constructs a distinctive flattened, protective case out of silk and debris (sand, fibers, dust) which it drags along with it. It can withdraw completely inside the case when threatened.

Generally harmless to humans (does not bite or sting), but is a household pest that can damage clothing, rugs, and fabrics made of natural fibers.
