Anthrenus verbasci
Varied Carpet Beetle
Anthrenus verbasci is a cosmopolitan pest species in the family Dermestidae, commonly known as the varied carpet beetle. Adults are small (2–4 mm), rounded beetles with distinctive patterned elytra bearing bands or spots of brown, black, and white scales. Larvae are covered in dense setae and feed on dried proteinaceous material, causing damage to household items, museum collections, and stored agricultural products. The species exhibits circannual control of its life cycle, with photoperiod serving as the primary zeitgeber for synchronizing pupation and adult emergence in spring. Adults feed on pollen and nectar, particularly from umbelliferous plants (Apiaceae) and Asteraceae, and use both olfaction and vision in host plant selection.
