Help much appreciated in narrowing this down. Everything I find in the guide that looks visually close to this seems out of range. Thanks!

Pachodynerus erynnis
Yes, you are correct. This is far outside the usual range for this species. However, P. erynnis is known to occasionally show up farther north, the farthest being southern Ontario (https://cjai.biologicalsurvey.ca/bmc_05/41p_erynnis.html). There also has been a recent sighting in New York (https://www.inaturalist.org/observations/33291119), within two days of yours! Possibly, these things get blown off course during hurricanes, which you have recently had along the Atrlantic Coast if I remember correctly.
Congratulations, a very interesting find!

Cool!
Thanks! Interesting info. I'm a birder so quite familiar with the "blown off course" thing for migrating birds, but not insects. Sure makes sense as a possibility though.

Adventive species
'Blown off course' was a bit sloppy as a characterization, my apologies. It is, of course, not comparable to birds. But there is a reference in the literature that notes that some of these adventive findings of P. erynnis happened after hurricanes. Of course, nobody can prove a causal connection. However, it is definitely a reasonable assumption that the dispersal of certain insect species (especially in the Caribbean and Florida) has been aided by hurricanes.
