Several different bees and bumblebees in a blooming cherry tree
Seen in a large field where lots of different flowers have been sown. There were lots of different bees (mainly Honey Bees) and bumblebees.
Looked like a queen searching for a nest site - at this time of the year???
Note last photo, which seems to be showing phoretic or parasitic mites.
A queen checking out potential nest sites. Sorry for the unfocused / blurred pics!
Buff-tailed Bumblebee, Erdhummel, Bombus terrestris.
