Appearance
This relatively small (3,5-5,5mm), usually brownish Polydrusus has bluntly rounded shoulders (no wings, hence flightless) carries long dark brushy hairs on the elytra between the long yellowish-brown scales.Distribution
Polydrusus inustus originates from eastern Europe, Russia and Asia but recently has been extending its range to areas in western Europe (Poland 1950´s, South of France 1972, Alsace 1996 etc), helped by human transports of plant material and parthogenetically reproducing females.Food
The beetles feed very polyphagous on a large number of deciduous trees, the larvae probably feed on the roots of these.References:
