A beetle that damages spruce trees and that was first detected in the UK in 1982, near Ludlow, Shropshire. Females excavate entrance holes near the base of the tree stem in each of which they lay up to 100 eggs. The egg galleries are interconnected and larvae feed on the inner layer of the bark and on phloem tissue.
