Fernald's Bumble Bee
(Cuckoo Bumble Bee)
Bombus fernaldae

This is a Cuckoo Bumble Bee. Just like the cuckoo birds, they lay their eggs in
other species nests and let them raise the young. They have no workers, only
males and queens, according to Wikipedia. © Carol Davis 5-27-2007

They also have no way to gather nectar. This one was feeding in the
Jordanelle Dam wetlands in Wasatch County, Utah. You can read more
about them on Bugguide (who ID'd this for me). © Carol Davis 5-27-2007
