I think it is a regular Bumble Bee that just happens to be more yellow. I cannot find any bee on-line that looks like that! It is a very pretty bee.

Thanks for the response Comettose, but I do think it's a different species. We also have the regular variety. It's a bit larger and slower and it makes much more of a buzz...

This little yellow bumblebee is essentially quiet and flits around at a much higher rate of speed. I do see some yellow species descibed on the web when I do a search, but none of them seem to quite match what we have. Apparently, much of the difference depends on the wing venation and unfortunately I don't have a good photo showing that aspect...

Bumblebees come in a number of different species. Those common in gardens are of the genus Bombus. So, for now you can call it a Bombus species.
