Verbasci was the first insect to be shown to have an annual and to date remains a classic example of circannual cycles in animals.
The body is covered in a pattern of alternating lightand darkbrown stripes.
The body is usually wider at the back than at the front and also bears 3 pairs of hair tufts along its rear abdomen that can be used for selfdefense.
Verbasci range from 1.
Their dorsal surface has scales of two colours, whitish and yellowishbrown.
White scales are condensed along the lateral margins of the pronotum.
In addition, their antennae are 11segmented with a club of 3 segments.
The length of the dormancy appears to depend on environmental factors, with the most likely being.
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.
Verbasci , one of the most wellstudied is the wasp laelius pedatus.
Upon discovering an a.
In response, the larva will erect long hairs on their abdomen and attempt to brush these hairs against the encroaching wasp.
The hairs detach and stick to the wasp on contact, presumably causing some sort of irritation.
Evidently, such irritation is not enough to deter an attack on a.
Verbasci larvae, as the vast majority of attacks are successful.
Such a defense, however, has been shown to be effective for the closely related species anthrenus flavipes , which has slightly longer hairs than a.
After a single successful sting, the beetle is permanently paralyzed.
The entire process from landing to complete paralysis lasts approximately 40 seconds.
Pedatus does not lay eggs immediately after the beetle is paralyzed, waiting as long as 24 hours before oviposition.
During this time, she grooms herself, removing any hairs that might have stuck to her during the attack.
They then spin cocoons near the empty shell of the host, emerging some time later as an adult wasp.
Verbasci is a common household pest.
Adult beetles usually lay their eggs in air ducts, in closets, under furniture, or under baseboards.
Once hatched and until they pupate into adults, the larvae hide in dark, undisturbed areas and feed on organic material.
The larvae are thus responsible for the damage of various items, such as furniture, clothing, blankets, furs, and carpets.
Collections of specimens, especially of insects, are also vulnerable to attack, making a.
Verbasci a common pest in museums.
Infestations can be prevented by regular vacuum cleaning, dry cleaning or airing clothing outside, placing balls in closets, and removing abandoned bird and insect nests attached to the building.
Signs of an infestation include the presence of damaged articles, molted larval skins in dark areas, and an abundance of adult beetles near windows.
Deterring or killing a.
Verbasci can be accomplished using , oxygen deprivation, freezing, and and scent traps.
