Black-shouldered Spinyleg
A large, elegant clubtail with distinctive spiny hind legs and black shoulder stripes. It perches conspicuously on rocks and logs along streams.
Did You Know?
The spiny projections on its hind legs form a basket used to scoop prey out of the air.
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.
