Black fir sawyer
Black fir sawyer (Monochamus urussovii) is an insect pest of conifer trees. It is a native of Eastern Europe and Asia.
This pest breeds in weakened or damaged trees affected by fire, windthrow, or recent cutting. Larval feeding creates large galleries in the wood. Adult feeding on needles can defoliate trees. This genus vectors pine wilt disease.
