Carpet beetle larval skin (likely)

Larvae occur indoors in carpets, upholstery, closets, and other undisturbed areas containing natural fibers; adults often visit flowers outdoors.

Larvae feed on wool, fur, feathers, hair, dead insects, and other keratin-rich materials; adults mainly consume pollen and nectar.

Larvae hide in dark areas and periodically shed bristly skins as they grow. Adults are small, rounded beetles and may enter homes through windows or vents.

Larvae can damage clothes, rugs, and stored animal products, and their hairs may irritate sensitive skin or airways. They also help decompose dead organic material; adults are minor pollinators.
