22-31 mm. Occurs in Europe, in the Caucasus and Siberia. Widespread in Hungary but only locally abundant. Sometimes a pest in poplar (Populus) and willow (Salix) forests. The female lays her eggs singly in small holes excavated in the bark at the base of the tree, where they overwinter. On hatching the larvae chew their way into the heartwood where they excavate vertical galleries 20-30 centimetres long. This greatly reduces of the value of the timber. They pupate in June at the lower end of these galleries. The adult emerge after 2-3 weeks and spend a further 1-2 weeks maturing in the pupal chamber. Several individuals can develop in the same trunk. Development takes 2-3 years. Adults can be found from late June until September on the trunk and branches of the foodplant, and on wood piles. Adults show maturation feeding behaviour on leaves of the same trees. Attracted to lights. Piles of frass and woodchips (as for the goat moth Cossus), and sometimes dying adults, can be found at the base of infested trees.
