3-3.5 mm. Bivoltine. The egg gallery is usually straight, sometimes forked. The larval tunnels are short and at right angles to the egg gallery. Common in dead wood and logs of oak (Quercus), occasionally develops in wood of other broad-leaved trees. Lives in a symbiotic relationship with ambrosia fungi. The larvae feed on the fungus instead of feeding on the woody tissue. Northern-, and Central-European species, common everywhere in Hungary.
