Carpet Beetle Larva (Shed skin/exuvia)
Scientific Name: Anthrenus verbasci (specifically Varied Carpet Beetle)
Order & Family: Order: Coleoptera, Family: Dermestidae
Size: Larvae grow to about 4–5 mm (0.16–0.20 inches) in length; adults are smaller (2-3 mm).
Natural Habitat
Indoor environments, particularly in dark, undisturbed areas like closets, under furniture, in carpets, baseboards, and stored woolens/fabrics.
Diet & Feeding
The larvae feed on natural fibers and protein-based materials including wool, silk, fur, feathers, leather, dead insects, pet dander, and dried food products. Adults feed on pollen and nectar outdoors.
Behavior Patterns
Larvae are photophobic (avoid light) and tend to wander in search of food. As they grow, they molt several times, leaving behind the translucent, golden-brown skins seen in the image. This shedding is often one of the first signs of an infestation.
Risks & Benefits
Risks: The larvae can cause significant damage to carpets, clothing (natural fibers), upholstery, and museum specimens. The tiny hairs (setae) on the larvae can cause allergic dermatitis or skin irritation in some people. Benefits: In nature, they act as decomposers of dead animal matter.
