Calliopsis (Nomadopsis) puellae - Calliopsis puellae - male - female

Calliopsis (Nomadopsis) puellae - Calliopsis puellae - Male Female
Anza-Borrego Desert State Park, San Diego County, California, USA
March 28, 2005
Size: right--BL 8.5-9 mm
We found these two bees on Desert Chicory (Rafinesquiae neomexicana) in Borrego Palm Canyon. They had just separated after mating. The BL of the right insect is about 8.5-9 mm. The wing venation suggests Panurginae. If yes, yellow integumental bands suggest Nomadopsis?

yes, these are indeed Calliopsis (Nomadopsis)
Probably C. puellae (Cockerell, 1933)

Here are my photos of this species mating on composites:

Post photos of face if possible (should be black in puellae)

 
your Calliopsis (Nomadopsis) puellae photos
I enjoyed looking at your pictures. The flowers are familiar. But the last photo was my favorite. Many years ago we found a group of bees in Hoberg Canyon in the Park. The bees were on the ground in a large sandy area and, we soon discovered, females were emerging and males were mating with them immediately. Sometimes two or three would roll into a ball and fly into the air. The photos, unfortunately, were poor. But we did find one dead male and were able to key it out to C. puellae. Your photo of the bees on sand reminded me of this exciting bee experience for us.

And thank you so much for identifying the bees. I did not realize that our dead specimen and these live bees were at least the same genus and possibly the same species.
