Carpet Beetle Larva (most likely Black Carpet Beetle or Varied Carpet Beetle)
Attagenus unicolor (Black Carpet Beetle) or Anthrenus verbasci (Varied Carpet Beetle)
- Order & Family
- Coleoptera, Dermestidae
- Size
- 2-5 mm in length
Natural Habitat
Indoors in homes, museums, warehouses; feeds on natural fibers like wool, silk, animal products (feathers, dried meat, fur), crumbs, and dust.
Diet & Feeding
Larvae of carpet beetles feed on a wide variety of animal and plant products, including natural fibers (wool, silk, sometimes cotton and linen if soiled), animal hides, pet hair, feathers, dried pet food, cereal products, museum specimens, and carpet. Adults feed on pollen and nectar outdoors.
Behavior Patterns
Larvae are typically found in dark, undisturbed areas. They are slow-moving and avoid light. They undergo several molts before pupating. The 'tail' or brush-like hairs on the end of the larva are distinctive. Adults are often found near windows as they are attracted to light and may fly in from outdoors.
Risks & Benefits
Risks: Can cause significant damage to natural fiber textiles (carpets, clothing, upholstery), museum collections, and stored food products. They can be a common household pest. Benefits: As scavengers, they play a role in decomposition in natural environments, but are mostly considered a pest indoors due to their destructive feeding habits.
