8-14 mm. Main foodplants are pine (Pinus) and spruce (Picea), occasionally found on other conifers and even on broad-leaved trees. The beetles emerge in late summer and early autumn. They overwinter at the base of stems or trunks, below the ground surface. After mating the females lay their eggs in fresh trunks or logs. Later they feed on the stem of young seedlings, usually causing death of the small tree. Only the adults are of importance in forestry. The white, 10-15 mm long larvae feed in the sapwood of trunks and logs. The head of the larva is yellowish brown. Clear-cutting as a management strategy is particularly suited to the requirements of this species. Wherever young conifers are planted after clearcuts without first removing the old trunks, mass infestation and damage will occur in a couple of years. In many European countries this species is considered as a major pest of young conifer stands.
