Balsam Fir Sawfly
A boreal sawfly whose dark green larvae with lighter stripes feed on balsam fir needles. Periodic outbreaks can cause significant defoliation in fir forests.
Did You Know?
Outbreaks of this species often follow those of the spruce budworm, as the already stressed trees are more susceptible to additional defoliation.
