These funny looking, fuzzy orange galls won’t hurt your oak tree, or you

Orange galls, fuzzy galls or fuzzy orange galls, no matter what you call them if you have an oak tree in your yard or on your property you likely have them. The culprit is the Cynipid wasp, a tiny member of the Vespidae family that lays its eggs on oak tree leaves.

“The gall is the plant or tree’s reaction to the insect’s egg,” said Jim Dill, pest management specialist with the University of Maine Cooperative Extension. “The leaf tissue grows around the wasp egg.”
