Carpet beetle

Carpet beetle (Anthrenus scrophulariae), destructive household insect whose larvae feed on carpets, rugs, furniture, fur, and clothing. The tiny (under 0.2 in/5 mm long), wormlike larvae, which do more damage than the adult, are the only beetle larvae covered with hair. Adult carpet beetles, which are brownish-black or marked with red or yellowish-white spots, are discovered in infested houses during spring, and are usually found on windowsills attempting to get out to feed on pollen.
