Case-bearing Clothes Moth
Scientific Name: Tinea pellionella
Order & Family: Lepidoptera (moths and butterflies), Tineidae (fungus moths and clothes moths)
Size: Larvae: up to 10-12 mm long; Adults: wingspan of 10-14 mm.

Natural Habitat
Indoors, in closets, attics, storage areas, and rarely used rooms where fabrics and textiles are stored. They prefer dark, humid, and undisturbed conditions.
Diet & Feeding
The larvae feed primarily on animal fibers such as wool, silk, fur, feathers, and felt. They can also feed on lint, dust, and synthetic fibers mixed with natural ones. Adults do not feed.
Behavior Patterns
Case-bearing clothes moths are typically found in dark, undisturbed areas. The larvae construct a silk case, often incorporating fibers from their food source, which they carry with them as they feed and grow. They are slow-moving and generally avoid light. Adults are weak fliers and are attracted to light but typically stay hidden.
Risks & Benefits
Potential risks: Clothes moths are considered pests due to the damage their larvae cause to natural fibers, resulting in holes in clothing, carpets, upholstered furniture, and other textile items. They do not pose direct health risks to humans. Benefits: Generally not considered beneficial in human environments, but as scavengers, they play a minor role in breaking down natural fibers in some ecosystems.
