Centris (Paracentris) on Palo Verde? - Centris pallida - male

Centris (Paracentris) on Palo Verde? - Centris pallida - Male
Claremont, Los Angeles County, California, USA
June 18, 2011
This bee was spotted in a Palo Verde tree (Cercidium sp.) at the Claremont Colleges' Robert J. Bernard Biological Field Station. The gray color was very striking – they looked almost blue while they were flying. I am thinking this must be Centris (subgenus Paracentris), which we've previously recorded (but not photographed) on Palo Verde at the field station. Any information will be greatly appreciated!


they're such fast fliers! How long did it take you to get him to sit still for a moment?

Not too long...
It didn't take too long. There were a lot of them around the Palo Verde, and one of them sat long enough to snap a few photos. Sometimes you just get lucky! I noticed that you got a nice shot of one next door at the Botanic Garden.

I've watched them for hours at RSABG
Doug Yanega told me he thought it was Centris pallida, and that it tends to follow Palo Verde plantings. Stood with my net for >2 hours, but always missed.

This will make you jealous...
I checked my camera data, and I can tell that I was only at the Palo Verde for about a minute before I took that photo. My experience last year was that the bees on the Palo Verde – both this one and the Megachile (Chelostomoides) – seemed to be very numerous when I first got to the Palo Verde, then made themselves scarce. So this time I had my camera ready to snap photos the minute I got there.

Thanks for the confirmation! This is a really cool bee!
