Probably Bombus mixtus? - Bombus -

Bandera Mountain, King County, Washington, USA
July 5, 2013

I think this is probably Bombus mixtus, but the thorax and abdomen have more black than I'd expect and it overall feels a little weird. Expert bee folk, is this within normal phenotypic variation expected for mixtus? Thanks!

(unfortunately, image 2 doesn't show up except in the thumbnail - it's a still from a video, so the resolution is probably too low to display other than the thumbnail)

Interesting - thanks! re

Interesting - thanks!

re: flavifrons - my guide shows the red variants of flavifrons as having yellow, red, black (anterior-posterior), but this bee has yellow, black, orange as far as I can tell. Is there a variant of flavifrons that matches this? Thanks!

correct

if tail tip is orange it can't be flavifrons
