UPDATED: After some more digging, I think they are just Pseudococcidae, which is what Lucy Dinsmore thought they were initially. So they are not braconids, sadly, and thus will not be any help for controlling spotted lanternfllies. Sorry to get your hopes up.
If you see an egg mass, nymph, or adult that is parasitized by wasps or infected by fungi, report it immediately — ideally to both iNaturalist and to your local extension agent — AND collect it in case somebody wants it. And tell me about it, too, please.
