The species is very polyphagous but oak is preferred in Central Europe. Larvae of this species feed in dead red-brown and relatively moist wood in close contact with living tissue, such as the bases of dead branches surrounded by living callus. The pupal cell as well as the larval galleries are filled with typical long red wood fibres created by the larvae.

Body length:	8 - 15 mm
Life cycle:	2 - 3 years
Adults in:	May - July
Host plant:	polyphagous in deciduous trees (Quercus, Fagus, Carpinus etc.)
Distribution:	Europe, Transcaucasia

The mounted beetle was reared from a larva found in a dead, rotten branch base attached to a living oak (Quercus robur). The branch was collected in a locality near Dobřichovice village (Central Bohemia, Czech Republic). The living beetles were collected on flowering hawthorn (Crataegus) in Dobřichovice and on a flowering Apiaceae plant in Broumy (Central Bohemia, Czech Republic).
