H ___ E ___L___ P what species of bumble bee is this?

oo

which species of the bumblebee is this?   I have many of these during this time of mid-May
I took this photo today.   I have a lot of bumble bees just like this one. I also have bees with
yellow bars and no yellow.
I am no expert on bumblebees.  The literature says the rusty patch has a range which includes the eastern United States.
I am not saying that this is a rusty patch but it sure does resemble one. 

Another possible rusty patch..   This is state of Washington, so I think it is unlikely unless the range for rusty patch is far larger than Easter United States.  See below
