Scientific Name: Anthrenus verbasci (likely Varied Carpet Beetle)

Order & Family: Order: Coleoptera; Family: Dermestidae

Size: 2mm to 5mm (larvae)

Carpet Beetle Larva (Molted Skin or Exuviae)

Natural Habitat

Indoor environments, particularly in dark, undisturbed areas like closets, attics, under furniture, or in carpet corners where natural fibers (wool, silk, fur) accumulate.

Diet & Feeding

Larvae feed on natural animal fibers including wool, silk, fur, feathers, leather, pet dander, and dried insects. They do not eat synthetic fabrics unless soiled with oils or food.

Behavior Patterns

The image likely depicts a cast skin (exuviae) left behind after molting, which is a key sign of infestation. Larvae are photophobic (avoid light) and tend to ruin fabrics by eating irregular holes. Adults eventually emerge to feed on pollen outside.

Risks & Benefits

Risks: Major pest of textiles, capable of causing significant damage to clothing, carpets, and museum specimens. Some people experience 'carpet beetle dermatitis,' an allergic skin reaction to the larval hairs (setae). Benefits: In nature, they act as decomposers of dead animal matter.
