Case-bearing Clothes Moth Larva

Natural Habitat

Indoors, particularly in dark, undisturbed areas such as closets, attics, storage chests, and under furniture, where natural fibers are present.

Diet & Feeding

Keratin-containing materials, including wool, fur, feathers, hair, felt, upholstered furniture, and occasionally synthetic fibers blended with natural ones. They also feed on lint and dust bunnies.

Behavior Patterns

The larva constructs a silk case around itself, incorporating fibers from its food source, which camouflages it. It carries this case wherever it moves, extending its head and legs from one end to feed. When disturbed, it can retreat fully into its case. They are slow-moving and prefer dark, secluded environments.

Risks & Benefits

Risks include significant damage to textiles, clothing, carpets, and other household items made of natural fibers. They do not bite or transmit diseases to humans. There are no known direct benefits, but as detritivores, they contribute to the breakdown of organic matter.
