Case-bearing Clothes Moth Larva

Natural Habitat

Indoors, particularly in dark, undisturbed areas such as closets, attics, and storage spaces, feeding on natural fibers.

Diet & Feeding

Keratin-containing materials, including wool, silk, fur, feathers, felt, and other animal products. They also feed on lint, dust, and synthetic fibers blended with natural ones.

Behavior Patterns

The larva constructs a portable silken case, often camouflaged with bits of the material it is feeding on, within which it lives and feeds. It can withdraw completely into the case if disturbed. They are slow-moving and prefer dark environments. The adult moths are poor fliers and tend to scurry or hop.

Risks & Benefits

Potential risks include significant damage to textiles, clothing, carpets, and other household items made of natural fibers. There are no known benefits to humans.
