Anthrenus verbasci
The varied carpet beetle (Anthrenus verbasci) is a 3 mm–long beetle that can be a serious household pest. It feeds on natural fibers and can damage carpets, furniture and clothing. A. verbasci was the first insect to be shown to have an annual circadian rhythm and to date remains a classic example of circannual cycles in animals. A. verbasci has an unusual life cycle for an insect, developing from larvae to adult in 1–3 years, depending on the environmental conditions. Larvae hatch from eggs in the spring and early summer, often in the nests of birds (including those of the House Sparrow and House Swift) or around stored fabrics. Larvae feed on natural fibers throughout their development, eventually experiencing a dormancy period (also known as diapause) prior to pupation into the adult stage. The length of the dormancy appears to depend on environmental factors, with the most likely zeitgeber being photoperiod. Adults emerge between late May and early August, flying to and feeding on the pollen of flowering plants. During this period, mating occurs, eggs are laid, and the cycle begins anew.

My husband regularly leaves the bathroom light on & our bathtub is a rich source of bugs! I only managed 2 photos of this tiny beetle before it flew away!
