Small Carpenter Bees - Hylaeus - male - female

Small Carpenter Bees - Hylaeus - Male Female
Mountain View, Santa Clara County, California, USA
May 13, 2009
Size: 1/4 inch
I have seen many of these insects in the area. It appears to me that they may be Small Carpenter Bees. I have observed this mating behavior in beetles before, but this is a first for me when it comes to bees. Any ideas?

I realize the quality of this image is poor -- perhaps to poor to receive a definite ID. However, I have moved it to this page because it is currently being referenced in an article in the forums (here).

No.
I believe these are in the genus Hylaeus, family Colletidae (note yellow bands on legs, which Ceratina doesn't have). Hard to tell conclusively from this image, though.
