Case-bearing Clothes Moth (larva)

Natural Habitat

Found indoors, especially in closets, carpets, and storage areas containing natural fibers.

Diet & Feeding

Keratin-rich materials such as wool, fur, feathers, hair, silk, and sometimes skin particles.

Behavior Patterns

Larvae construct a portable silken case incorporating fibers from the material they feed on. They remain inside this case while feeding and molting, eventually pupating within it.

Risks & Benefits

No health risk to humans, but can cause significant damage to clothing, upholstery, and rugs. Ecologically, they help break down animal-based organic waste.
