Scientific Name: Anthrenus verbasci (commonly Varied Carpet Beetle)
Order & Family: Coleoptera; Dermestidae
Size: Larvae range from 4 to 5 mm in length; adults are smaller, around 2 to 3 mm.
Natural Habitat
Typically found indoors in dark, undisturbed areas such as closets, under furniture, in carpets, or near natural fibers like wool and silk. Outdoors, adults are found on flowers.
Diet & Feeding
Larvae feed on natural fibers (wool, silk, fur, feathers), dried plant materials, dead insects, and pet hair. Adults feed on pollen and nectar.
Behavior Patterns
Larvae are photophobic (avoid light) and tend to burrow into fabrics or debris. They are the destructive stage of the life cycle. Adults are attracted to light and are often found near windows.
Risks & Benefits
Risks: Larvae can cause significant damage to carpets, clothing, upholstery, and museum specimens. Some people may develop allergic reactions (dermatitis) from the larvae's bristly hairs. Benefits: In nature, they help decompose dead organic matter, though they are major pests in homes.
