Jumping galls on oak leaf (I think burr oak, but could also be swamp white oak)
Q. macrocarpa. q-macrocarpa-hairy-glob? (or saltatorius?) Spots on upper side of the leaf appear flat. Zillions of these galls on this tree. Sending two leaves with many galls to Forbes lab
common on this particular oak. An adult emerging(?) in third picture.
On what I think was Swamp White Oak (196712890)
