Case-bearing Clothes Moth (Larval case)

Natural Habitat

Typically found indoors in closets, cupboards, and undisturbed areas with natural fibers (wool carpets, clothing, furs).

Diet & Feeding

Larvae feed on keratin-rich materials such as wool, fur, feathers, hair, felt, and sometimes stored food products.

Behavior Patterns

The larva constructs a silken case around its body, incorporating fibers from the material it is eating for camouflage. It carries this portable case with it as it feeds and moves, retreating inside when disturbed.

Risks & Benefits

Risks: Major pest of textiles; larvae can cause significant damage to expensive clothing, rugs, and upholstery. Benefits: None in a household setting; in nature, they aid in decomposition of animal matter.
