Case-bearing clothes moth larva (likely)

Dark, undisturbed indoor areas such as closets, carpets, upholstery, and stored textiles; larvae often remain inside portable silk-and-fiber cases.

Larvae feed on keratin-containing materials, especially wool, fur, feathers, hair, and silk, often consuming soiled or stained fibers. Adults do not feed on fabrics.

Larvae avoid light and crawl while concealed in a rough, fiber-covered case, pupating within protected cracks or furnishings. Adults are small, buff-colored moths and are weak fliers.

They can damage clothing, carpets, and natural-fiber furnishings but do not bite people or transmit disease. Identification from this photo is tentative because the object could also be a small debris-covered moth case.
