I think you are right about the leaf hopper. That seems to be exactly what it is. I looked "leaf hopper" up and that's exactly how they are. They hop around and some fly. Though their coloration is actually quite pretty. They suck the plant juices and some exude sticky like honey which explains why there was some honey like stuff on one of the leaves and ants were surrounding it. Hope it doesn't become a big problem for the tree.
As for the figs, I don't know anything about it. I only have figlets forming. I only heard from the nursery that people really like them. Hoping someone else has info on them.
