Rose-stem Gall Wasp
A gall wasp that creates spiny galls on the stems of wild roses in North America. Each gall contains a single larval cell surrounded by hard woody tissue.
Did You Know?
Its galls often persist on rose stems for years after the wasp has emerged, serving as shelter for other insects.
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.
