Which Wasp Please - Chalybion californicum - female

Which Wasp Please - Chalybion californicum - Female
Brighton, Northumberland, Ontario, Canada
July 1, 2010
We have had quite a few of these around this year. How can I tell whether they are Steel Blue Cricket Hunters or Blue Mud Daubers. Help would be appreciated.

Male!
Naomi, your wasp has eleven flagellomeres and the females only have ten of them. In the second image, on the right-side antenna, they are easier to count. Also, his abdomen has all of the male qualities. (7 tergites)
Please note that after the last five years of placing our images, I'm sure that Dr. Ascher would now also agree with my analysis of your wasp.
Here is a link to my wasp's images, with more information that you may want to see:
Thanks
