Dear Melissa,
We just posted a photo taken at our offices in Mount Washington yesterday of similar male Valley Carpenter Bees nectaring on wisteria.  We believe male bees emerge first and defend territory against other males, though that is just speculation.  The seem much more wary and flighty than the larger black females that are so sexually dimorphic that they appear to be a different species.  Female Valley Carpenter Bees are the largest Bees in California, and their eggs, according to BugGuide, are the largest of all insect eggs.
