This bee was visiting flowers in our backyard around mid-afternoon. Can anyone ID it and explain what those 'sacs' are on it's hind legs?

Moved from Bumble Bees.


B. borealis
not fervidus

Thank you!
The Natural History Museum web page for Subterraneobombus shows that one species of Subterranobombus is known to live in Newfoundland.  If this image is of a Bombus (St.) borealis Kirby, 1837-272, then I guess this must be the species that they are talking about. Thank you for the correction.

this is the species
how about moving the image to the right guide page?

I've moved these images to the Bombus page because there is no Guide Page for the species B. borealis. Hopefully an editor will create one.

Mardon, this is a bumblebee in the genus Bombus. The sacs you are talking about are 'pollen baskets' called corbicula, (singular: corbiculum). All bees in the family Apidae have them

Thanks - Moved
Thanks, Omar. Adalbert Goertz also ID'd this individual as Bombus fervidus, Golden Northern Bumble bee, so I've moved these images to the species page. Thanks also for the explination of the corbicula. I'm learning more each day! :)
