Not sure whether it's a hoverfly or similar mimic of a bumblebee. On border of woodland / calcareous grassland.
No interactions present.
This is one of four colour forms of the species: black or yellow-striped, each with a red or white tail. This one resembles Bombus lapidarius. The yellow-striped ones (overwhelmingly the commonest in Scotland at least) are passably good mimics of the white-tailed bumbles and B. pratorum. The black-and-white one seems to have missed the target! Most of the 'other observations' here are the plumata form - striped with a white tail.
