This fly was resting on a fucsia flower leaf.
And from the leaf scale you can get it`s size.
It is big and I would like to know what fly it is.
No interactions present.
The scutellum colour is not critical in ID. These two species are superficially vaguely similar, but utterly different in jizz and detail. L. lucorum has a richly brown-haired thorax, and a much neater overall appearance. The re-entrant vein is clear in the pic, and that immediately excludes L. lucorum even if nothing else does.

Like others in the genus, this lives as a larva in the nests of wasps or bees. I have seen adult V. pellucens slowly sneaking into active wasp nests in a very sly manner, avoiding the attention of the workers as best they can.
