Carpet Beetle
Scientific Name: There are several common species, including Anthrenus scrophulariae (Common Carpet Beetle), Attagenus unicolor (Black Carpet Beetle), and Trogoderma variabile (Warehouse Beetle). Based on the image, they most closely resemble Anthrenus species or Attagenus species.
Order & Family: Order: Coleoptera, Family: Dermestidae
Size: Adults typically range from 2-5 mm (0.08-0.2 inches) in length. Larvae can be slightly larger.
Natural Habitat
Indoors, they are commonly found in homes, museums, warehouses, and anywhere animal-based products are stored. Outdoors, adult beetles can be found on flowering plants.
Diet & Feeding
Larvae feed on animal products such as wool, silk, leather, fur, feathers, and dried pet food. They can also feed on plant materials like cereals, spices, and dried plant products. Adults primarily feed on pollen and nectar.
Behavior Patterns
Carpet beetles often play dead when disturbed. Larvae are typically found in dark, undisturbed areas where their food sources are abundant. Adults are attracted to light and may be found near windows. Adults can fly. They undergo complete metamorphosis with egg, larval, pupal, and adult stages.
Risks & Benefits
Potential risks include damage to personal belongings (clothing, carpets, furniture) and stored products. Some people may experience skin irritation or allergic reactions from bristles shed by the larvae. They are generally not harmful to humans or pets directly. Benefits are minimal in a human-dominated environment, but they play a role in decomposition in natural settings.
