Carpet Beetle larvae casing/shed skin
Scientific Name: Anthrenus scrophulariae (Common carpet beetle), Anthrenus verbasci (Varied carpet beetle) etc.
Order & Family: Coleoptera, Dermestidae
Size: Shed casings are typically tiny, a few millimeters in length, reflecting the size of the larva at the time of molting (larvae typically 2-5 mm).
Natural Habitat
Indoors, commonly found in areas with natural fibers like carpets, rugs, woolen items, upholstered furniture, and stored food products. Outdoors, they can be found in bird nests, animal carcasses, and dried plant matter.
Diet & Feeding
Larvae feed on a variety of animal and plant products, including wool, silk, feathers, leather, fur, dead insects, pet hair, stored grains, and dried foods. Adults feed on pollen and nectar.
Behavior Patterns
The image shows shed skins or casings of carpet beetle larvae. Carpet beetle larvae molt multiple times as they grow, leaving behind these characteristic bristly, often striped casings. They are typically slow-moving and prefer dark, undisturbed areas. Adults are winged and are attracted to light, often flying to windows.
Risks & Benefits
Potential risks include significant damage to natural fiber textiles, clothing, carpets, and stored food products. They do not bite or transmit diseases to humans or pets, but their bristly hairs can cause skin irritation in some individuals. They are considered pests indoors. In nature, they play a role as scavengers.
