Case-bearing Clothes Moth

Natural Habitat

Indoors, especially in undisturbed areas like closets, attics, and storage spaces, where natural fibers or animal products are present.

Diet & Feeding

Larvae feed on natural fibers of animal origin, including wool, fur, silk, feathers, felt, and leather. They can also consume lint, dust, and synthetic fibers if mixed with natural ones. Adults do not feed.

Behavior Patterns

Larvae construct a silken case out of the fibers they are consuming, which they carry with them as they move and feed. They are typically slow-moving and prefer dark, undisturbed areas. Adults are active flyers but are often seen fluttering weakly or crawling. They are attracted to light but prefer to stay hidden. The entire life cycle from egg to adult can take 2-4 months depending on conditions.

Risks & Benefits

Potential risks: Clothes moths are considered pests as their larvae cause significant damage to clothing, carpets, upholstery, and other items made of natural fibers, leading to economic losses. They do not pose direct health risks to humans. Potential benefits: None for humans; in natural environments, they contribute to the decomposition of animal remains and shed fur/feathers, acting as detritivores.
