Case-bearing Clothes Moth (Larva)
Scientific Name: Tinea pellionella
Order & Family: Lepidoptera (moths and butterflies), Tineidae (fungus moths and clothes moths)
Size: Larvae typically 4-10 mm (0.16-0.39 inches) in length; adults have a wingspan of 9-16 mm (0.35-0.63 inches).
Natural Habitat
Indoors in dark, undisturbed areas where suitable food sources are stored, such as closets, attics, under furniture, and in storage chests. They prefer areas with higher humidity but can survive in dry conditions.
Diet & Feeding
Primarily keratin-containing materials such as wool, fur, feathers, hair, felt, and sometimes synthetic blends or soiled fabrics. They can also feed on lint and debris.
Behavior Patterns
Case-bearing clothes moth larvae build and carry a silken case, often camouflaged with fibers from their food source. They are secretive and avoid light. The larvae are the damaging stage, while adult moths do not feed. Females lay eggs on suitable food sources.
Risks & Benefits
Risks: Significant pest of textiles, causing damage to clothing, carpets, upholstery, and other natural fiber products. Benefits: No direct benefits to humans, but as decomposers, they play a minor role in breaking down natural fibers in the environment.
