On some kind of red oak (196177282).
White hind trochanter indicates female.
Bycatch from UV moth light trap, so apologies for the scales caked on the specimens. I can provide other views if needed for IDs.
Love these wasps with all my heart
UPDATE: ITS A SAWFLY! love them all the same
Noah Meier 2023: …this is a quite distinct species, Dusona bicoloripes. You can key it with Horstmann (2009) based on the 3rd laterotergite folded in, 5th tergite red, the propodeum being hardly depressed, and the hind tibia black(ish).
