8-14 mm. Occurs throughout Europe, North Africa, the Caucasus, from Siberia to Korea and in North America. In Hungary common in a range of habitats. Can be a pest of young poplar and willow stands. Larvae develop in branches and stems 1-2.5 centimetres in diameter, particularly of trembling aspen (Populus tremula). Female egglaying behaviour is characteristic. A horse shoe-shaped depression is cut into the bark through to the sapwood, and a single egg laid in each. These depressions may be closely grouped. This activity causes a gall-like swelling on the affected stem. The larva first feeds on the wound tissues induced by egglaying and then moves to the heartwood, where they pupate the following spring. Development takes one year. Adults can be seen in May and June, feeding on leaves of the foodplant.
