Case-bearing Clothes Moth larva

Natural Habitat

Indoors, especially in dark, undisturbed areas where animal-based fibers are stored (e.g., closets, attics, under furniture).

Diet & Feeding

Larvae feed on natural fibers of animal origin, such as wool, fur, feathers, hair, felt, and silk. They create a silken case for protection, incorporating fibers from their food source.

Behavior Patterns

The larva constructs a portable, silken case that it carries everywhere. It feeds from both ends of the case, enlarging it as it grows. Adults are nocturnal, weak fliers, and are often found crawling or running, preferring dark areas.

Risks & Benefits

Risks: This insect is a significant pest of stored natural fibers, causing damage to clothing, carpets, upholstered furniture, and museum specimens. They do not pose direct health risks to humans. Benefits: No direct benefits are associated with this pest, but like all organisms, they play a minor role in decomposition in natural environments.
