Natural Habitat

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

Diet & Feeding

Larvae feed on natural fibers such as wool, silk, fur, feathers, and other animal products. They are considered pests of stored goods and textiles.

Behavior Patterns

Case-bearing insects live inside a protective case made of silk and debris. They carry this case with them as they move and grow. The larvae are often found in quiet, undisturbed areas. Adults are typically short-lived and focused on reproduction.

Risks & Benefits

Risk: Significant pest of textiles, clothing, carpets, and other items made of natural fibers, causing damage through feeding. Benefit: None for humans, though they play a role in natural decomposition in ecosystems.
