Psyllid gall, but not psyllid larva

I agree with this move. I believe this an a old gall from the previous growing season and based on another ID that Charley Eiseman did for me of a fresh gall, I suspect the original gall-maker was - as G.K. suggested - a psyllid:

I am not an expert on insect larvae, but the large larva in the final photo is certainly not a tiny psyllid, so is more likely an opportunist that discovered this old gall.

Hackberry

Although I have no scale to judge size, the leaves in your host plant photo seem rather small and squat to me to be Common Hackberry (Celtis occidentalis), I wonder if this might be Dwarf Hackberry (Celtis tenuifolia). The latter is a shrub or small tree, the former a tree (which of course start out as saplings). Both occur in Virginia.

Probably the Dwarf Hackberry

The plant is not a tree unless very young, more of a tall shrub, so it is probably the Dwarf Hackberry.
