Bombus hortorum worker warming up

I photographed this Bombus hortorum worker warming up on a stone in my rockery a few weeks ago. The rockery is south facing, so catches any sun there is. This year the stones have been covered in bees, hoverflies and butterflies, all trying to get a little warmth in this miserable summer. Today all that are left are some very ragged Bombus pascuorum workers and males, and hoverflies. It has been a very bad year for most bumblebee species in my garden, but a very good year for Bombus hortorum. Perhaps that is because the queens emerged later and missed the early good weather that was followed by deep snow.
