I'm sorry the focus isnt right in the images. There are green bulbs on the down sides of leaves of this tree (poplar I think). On the upper side, it leaves craters. I cant tell if those are insect parasites or some other illness

There’s a gall wasp that lays eggs in hackberry leaves. It’s normal, doesn’t really harm the tree.
