I guess I beat Eric to it...
I don't know if he'll be commenting on this long weekend but I can offer an ID. This looks like a female Calopompilus maculipennis (Pompilidae). The legs and antennae are rather short for a Pompilid and coupled with these features it makes the large, orange subapical spot on the anterior wings diagnostic.

C. maculipennis
why can i not find these... also, do you have any suggestions on identifying an Auplopus to species?

E-mail me about this. If you don't have Townes, I'll hook you up with those keys. Apparently no new nearctic Auplopus has been described since then.

because they're rare! There is record from Imboden, Arkansas (Townes, 1957) and this species is found throughout the southern half of the U.S. east of the Rockies. Unfortunately the genus as a whole is very rare and would probably take some intense searching to find it. I've only ever seen one live specimen of C. fortis in Ohio, and that's supposed to be the most common species!
