St. Andrews wasp from Quercus laevis 2019 1
Laurinburg, Scotland County, North Carolina, USA
October 3, 2019
Is this a gall wasp or a parasitiod wasp? It emerged from a bagged leaf of Quercus laevis, but I am not sure whether it may have emerged from a gall I missed, or whether it is a parasitoid on an insect in there...

It is ...
... NOT a gall wasp (family Cynipidae). That said, it is possible that it emerged from a gall, as either a parasitoid or inquiline, or that it came from a leaf miner. It looks like a member of the superfamily Chalcidoidea, very likely the family Eulophidae (which includes species that have been reared from galls and leaf miners).

Chalcid…
Assuming the host plant is turkey oak that you mention, then it is possible that this may be a eulophid wasp, since many are mentioned in the literature as being associated with this particular species of oak.

Eulophids are extremely diverse in their habits, some attacking the larvae or pupae of gall insects, others the plants themselves. It is quite possible that this wasp emerged from a leaf-miner or a gall-former, but we would need a closer view to take this ID further.
