Not sure if this a bumble or carpenter bee? Seems to have a hairy abdomen... which makes me think Bumble... but the blue-gray eyes make me think Xylocopa... or could it be a Digger Bee? This one was in Echinocereus ... habitat is desert upland mixed with chaparral and pine-oak woodland on the terraces above a riparian woodland.
