Wing veins are quite interesting.

Thanks. I'm hoping that will help in perhaps identifying this wasp. Late in fall these wasps do like the grape jelly.

Forewing venation does help - Belytinae
One example of a very slender member of this subfamily of the Diapriidae (Proctotrypoidea). Despite their length, slightly clubbed antennae seemingly lacking the famous "modified segment" at the basis of the flagellum suggest a female.
These small wasps are most encountered late in the season, because they develop mainly in mushrooms (as parasitoid of Mycetophilid larvae).
