Moved
Moved from Gastrosericina.

Female - Tachytes sp. (small-size group)
Based on the flower size, I would say that she isn't very much bigger than a Honeybee. Is that correct?
The truncated abdomen and the thick, spiny legs rule out Tachysphex and that along with her big, pretty eyes, also rule out Larropsis.
I can't say which species yet, but you can check the boxes and move her to genus level for now. Thanks! - 6 abdominal segments = ♀

 
Thanks, Bob
I don't remember the wasp, but do the location. As you probably know, it's on buckwheat. I think you have the size right.

Moved
Moved from Larrini.

 
Thanks, John.

Moved
Moved from Larrinae.

Sphecid
I think this is a Larrine Sphecid, maybe Tachytes. Eric Eaton will know for sure.

 
Probably.
Probably is Tachytes, but the smaller they are, the more you can't rule out Tachysphex:-) Definitely in the Sphecidae, subfamily Larrinae, and I would lean toward Tachytes.

 
The die is cast.
Thanks, Eric.

Sphecodes ? (Halictidae)
Cuckoo bee?

 
Thanks, all.
Guess I should wait for Eric.
