Pseudoynerus? - Euodynerus megaera - female

Pseudoynerus? - Euodynerus megaera - Female
Lake Placid, Highlands County, Florida, USA
May 2, 2010
This wasp was gathering sand in a small patch along with a dozen or more other wasps, there were at least three species represented. Pseudoynerus is a wild stab based on previous ID'd photos. This wasp appeared very similar in to another example I photographed at the same location except this one had second yellow/white ring on the rear of the abdomen.
The other wasp is here:

Pseudoynerus? - Euodynerus megaera - female Pseudoynerus? - Euodynerus megaera - female

Euodynerus megaera
Moved from Euodynerus schwarzi. I have looked at hundreds of Eumeninae from FL, and I have never seen E. schwarzi from that state. It could possibly occur in northern FL, whereas E. megaera is common throughout the state.

Not certain
I am not convinced this is E. schwarzi but the angle is a little unfortunate to be sure.


Euodynerus sp. - female
Either E. megaera or E. schwarzi. Unfortunately, the main distinctive feature - i.e., presence or lack of white on tibiae - isn't visible here.

Thank you
In the shot before this one the middle leg is not shadowed by the wings and I can see the middle section of the middle (left) leg is white. Is this the feature needed? I will add that shot; hopefully it will be helpful. Thank you for explaining the needed distinctive feature and taking the time to help with this ID.
