Black and yellow are the universal warning colors among animals able to see them. It looks like someone forgot the black on this bumblebee. This turns out to be one of the varied colorations of Bombus perplexus*, the "perplexing bumblebee." It's one of the least perplexing, since all-yellow bumblebees are not the norm. A bugguide contributor pointed out that it's also a male--unable to sting--and not anything to warn anyone about anyway.
