My father found the attached "attacking" foraging honey-bees.
He said it was very fast flying and un-phased by him trying to catch it. It had a very distinctive yellow face. When it caught a bee, they would drop to the ground, "wrestle" and then it would fly off in search of another. This was so fast he was unable to see what was happening.
I assume this is a male trying to find a mate?
My father caught this one, subdued it in the fridge so he could photographic it and then released it.
It seems to bear some resemblance to Andrena ovatula but seems plumper and more hairy (younger?) than other images that I've found.
This one was caught in somerset near Weston-super-Mare if that helps.
