wasp for ID - Prionyx - Female
Arvada, Jefferson County, Colorado, USA
June 24, 2009
Size: abt. 15-18 mm
I filed this away thinking it was just another Isodontia mexicana, but after reviewing it now,
I believe I have something else. Could this be a Prionyx or Podalonia? Thanks for the help.

Yes:-)
Sorry:-) This appears to be a species of Prionyx, either P. atratus or P. subatratus. Note the body is stockier than in Podalonia, and the legs are noticeably spinier, too. Lastly, Prionyx often has a short extension on the tip of the abdomen, visible in the third image. This is a female specimen.

Thanks.
Thank you Eric. These are very helpful tips, and this was a good lesson in the merits of reviewing summer images in the fall. I took so many this year, I felt overwhelmed trying to keep up. I have no images of Prionyx so this is a welcome ID!! Please see my updated bio for our test gardens - we found over 60 bee species this year, and our wasp count is around 25 species.

Don't forget to add this information when you have it. I did it for you this time.
