Carpet Beetle Larva (Specifically, a piece of debris or frass resembling one, or a dried larval casing)
Scientific Name: Anthrenus verbasci (Varied Carpet Beetle)
Order & Family: Order: Coleoptera, Family: Dermestidae
Size: Larvae range from 4-5 mm in length; adults are smaller (2-3 mm).
Natural Habitat
Typically found indoors in dark, undisturbed areas like closets, under furniture, in carpets, and near stored natural fibers (wool, silk, fur).
Diet & Feeding
Larvae feed on natural animal fibers such as wool, fur, feathers, silk, shed pet hair, and dried skin flakes. Adults feed on pollen and nectar.
Behavior Patterns
Larvae thrive in dark places and move slowly. They shed their skins multiple times as they grow, leaving behind hairy, translucent shells. The object in the image appears to be a dried casing or a very curled larva.
Risks & Benefits
Risks: Larvae can cause significant damage to carpets, clothing, and upholstery made from natural fibers. Some individuals may experience an allergic reaction (dermatitis) upon contact with the larval hairs. No direct bite to humans but considered a household pest.
