A.Verbasci is a very distinctive, easily recognised beetle that can be a serious problem in the house. It feeds on natural fibres and can damage anything of natural origin, woolen carpets, furniture} and clothing.
The larvae are known as a woolly bear, a name it shares with the larvae of Pyrrharctia isabella or the Isabella Tiger moth.

A. verbasci was the very first insect to be shown to have a circadian and an annual cycle and to this date remains a classic example of

circannual cycles in insects.
The larval form of A. verbasci are circa 4-5 mm in length. The body has a pattern of alternating light- and dark-brown stripes. The body of the larvae is usually wider at the back than at the front and contains 3 pairs of hair tufts on its rear abdomen that can be used for self-defence

Adult insects range from 1.7 to 3.5 mm in length. Their dorsal surface has scales of two colours, whitish and yellowish-brown. White scales are condensed along the lateral margins of the pronotum. In addition, their antennae are 11-segmented with a club of 3 segments
A Verbasci has a very unusual life cycle for an insect, developing from larvae to adult in 1-3 years, according to the environment in which it finds itself.
Larvae hatch from eggs in the spring, very often they are associated with birds’  nests or around stored natural fabrics Larvae eat natural fibres throughout their larval stage, eventually experiencing a dormancy or diapause before completing pupation and emerging as an adult. Adults emerge between  March and early August, and feed on pollen.
These insects cause both physical damage by their larvae eating fabrics and psychological damage from the vast numbers of these pests which can emerge into living quarters.
When attempting to deal with these insects it is important to look for the presence of birds’ nests and remove any nests and feathers etc from the affected area before treating with an appropriate insecticide..
It is important to keep in mind that in the U.K. legislation affects the removal of birds’ nest, including sparrows and starlings which are the two common birds which have an association with A.verbasci so professional assistance should be sought to avoid [breaking the law.
