Update
According to a comment on this iNat observation, X. spectrum is no longer considered a North American species. I suspect this belongs on the "X. caudatus or X. Melancholicus" page, but I'll leave it at genus until someone with actual expertise takes a look at these. :)

Moved
Moved from Xeris spectrum.

Moved to genus just to be safe. With luck, an actual expert will weigh in. :)

I will note, however, that X. pallicoxae appears to be a European species. Yours is the only North American data point on iNat.

Added a photo
I also uploaded this guy to iNat and recieved a comment that due to the light-coloured coxae this is actually X. pallicoxae. Just added a photo that better shows this feature.
