I’m leaving this up so that it might help someone else. I just got my answer from Penn state extension. It is the nymph stage of the spotted lantern fly. Highly invasive and damaging to trees. It is treatable with pesticides and banding trees.

Whitefly can turn into a major problem when they are allowed to multiply with no attempt at control. These insects hangout on the underside of the leaves as adults. That is also where they lay their eggs which hatch into the small, translucent disc shaped nymphs clearly visible on the leaves. Your control measures will require that you do something to get rid of all three stages: eggs, nymphs, and adults. Inside, use those sticky traps for adults, but change them occasionally. I never recommend them for the garden because they can catch too many other things like beneficial parasitoid wasps, butterflies, bees, tree frogs, spiders, and little lizards. I prefer a horticultural oil for the control of eggs and nymphs, but it must be applied directly to the underside of the leaves. Oils will smother the pests very effectively. Repeat the applications every week or so until you stop seeing the adults flitting around. Whiteflies are very mobile. Keep an eye on your other plants, too.

Lacking any visible evidence to say otherwise, I'd guess plum curculio. But without any photos, this is just speculation.
