Dorsal surface with scales of two colors: white and yellowish brown. White scales on pronotum on each side condensed in a spot near anteriour angles and two (often confluent) patches in the posteriour half; white scales may be found on the posteriour margin also, but not forming a distinct prescutellar spot. Elytra with several white spots (usually partly merging): one on base near, but not touching, scutellum, the remaining arranged into three transverse bands.Important characters apart from colour: Eyes with inner frontal margin distinctly notched (unlike in verbasci), antennae 11-segmented with 3-segmented club.

2-3.5 mm.
Similar Taxa
Sometimes confused with A. verbasci, in which the colour pattern is a little different, and eyes not notched.

BIOLOGY
Importance
In modern households, larvae feed on a variety of organic substrates, incl. wool, silk, fur, feathers, and dry animal material (larvae will not fully develop if fed on pure wool unless it is impregnated with some other animal product); larvae will feed on book bindings, chew holes in paper, and are attracted to and feed on dead animals
