Glad I stayed with this bee. - Xenoglossa strenua -
Peters Canyon, Orange, Orange County, California, USA May 26, 2009
It looked like a honey bee, but didn't move like one, plus it was way more wary. Shot it deep inside a gourd flower in bad light, so images aren't all that hot.
The moral of this story is don't blow off what you think is a common insect...until you're dead certain it is a common insect.
