Sphecidae! - Palmodes - Female
Santa Cruz, RMG, Santa Cruz County, California, USA
June 18, 2015
Size: ~18mm
Sphecidae! Not Pompilidae as I had guessed!

I was surprised to read that most Pompilidae are 15mm or larger, because the majority that I see don't seem that larger. I seem to mostly seen under 15mm ones here in the bay area. This one had shiny reflective wings, which it clapped with enthusiasm.

I wanted to mention the blue hair around the body. It was distinctive enough to see with the naked eyes.

The antennas look odd until you realize the large antenna segment over the face blends in with the face so that at first the top of the first antenna segment looks like the attachment to the face.

Overall the picture is too dark, and I've attempted to lighten it. Having done so I can see much resemblance to Chalybion californicum. It doesn't seem like it exhibits the very vivid metallic blue, though.

I don't expect much help with ID but anything would be helpful as this is one of the flashiest things around.

Podalonia? Females of Palmodes are supposed to have the clypeus sinuate and indented on the sides and the tarsal claws (hard to see, but they are supposed to be well-toothed in Palmodes) are more like Ammophilinae. Can't see many of these features well, though.


Thanks! Interesting Genus - Hope I see more!
I do see a lot of "nymphal tettigoniids" here. Particularly the the ones with striped antennas. So she came to the right place to find them!
