features
The light-colored rodent beetle reaches a size of around four millimeters. On the pronotum and the wing covers there is a conspicuous drawing made up of whitish brown hairs. The punctuation below is covered by this. The wing covers have no longitudinal ribs. The pronotum has a high keel and is provided with a sharp edge that, when viewed from the side, forms approximately a right angle. There are individual, protruding black bristles between the basic scales. The bright drawing of the elytra also includes the tips of the elytra.

Way of life

In contrast to wood worms, dry construction or furniture wood is not attacked by this species . The adult beetles feed on pollen and nectar from flowering shrubs such as blackthorn ( Prunus spinosa ) or hawthorn ( Crataegus ).
