Tinea pellionella (Case-bearing Clothes Moth larva)

Natural Habitat

Found indoors in residential homes, warehouses, and locations with stored natural fibers like wool, silk, or fur.

Diet & Feeding

Larvae feed on keratin-containing materials such as wool, feathers, fur, hair, and sometimes synthetic fibers blended with natural ones.

Behavior Patterns

Larvae construct and live inside a portable silken case incorporating debris and fibers. They move by extending their heads and legs to drag the case along. They prefer dark, undisturbed areas.

Risks & Benefits

They are serious household pests that cause damage to clothing, upholstery, and carpets. They offer no direct benefits to humans but serve as decomposers in natural ecosystems by breaking down animal remains.
