3.5-5 mm. Regularly univoltine, but can be bivoltine. Foodplants are pine (Pinus) species. The beetles overwinter at the base of older trees, under the bark, and emerge in March-April. The females oviposit in thicker-barked parts of dead or dying trees. Stands damaged by snow are particularly favourable for ovipositing. The egg gallery is single-shafted, more or less vertical, but sometimes bending, ca. 2 mm wide and 10-15 cm long. The more or less horizontal larval tunnels are long. The new generation emerges in July and August. The young beetles feed inside the current year's shoots. The shoot becomes dry and breaks down above the attack. On the first frosty days the beetles migrate to overwintering sites. Palaearctic species, occurs everywhere in Hungary where its main foodplant P. sylvestris is present.
