Identification
Adult A. verbasci range from 1.7 to 3.5 mm (0.07 to 0.14 in) in length. The body is rounded, almost spherical. Elytra and pronotum have an irregular pattern of white, brownish and yellowish patches formed by scales of different colours. Whitish scales are condensed along the lateral margins of the pronotum and on on the elytra, where they form three bright, wavy transversal bands. In addition, their antennae are 11-segmented with a club of 3 segments.
The larval form of A. verbasci are roughly 4–5 millimetres (0.16–0.20 in) in length. The larvae are elongate and densely hairy. The body is covered in a pattern of alternating light- and dark-brown 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 self-defense.
