Quiescent bumblebee

Observation - Quiescent bumblebee. Description: White-tailed but no double-yellow band on the thorax; also face not obviously longer than wide - so not B. hortorum I think. Facial hair yellow, not black, so not a male B. terrestris. Despite the white tail, the banding is not definitively lemon-yellow,

White-tailed but no double-yellow band on the thorax; also face not obviously longer than wide - so not B. hortorum I think. Facial hair yellow, not black, so not a male B. terrestris. Despite the white tail, the banding is not definitively lemon-yellow, arguing against the B. lucorum complex.
So, a B. terrestris/lucorum worker?
