I have keyed out this small (5mm), black, male fly as
Dufouria chalybeata. As I have not seen this species before I would be grateful for confirmation.
On Hogweed (
Heracleum sphondylium) flowers, grazing marsh, south Essex, England, 14 June 2017.

That is totally OK.
Here in western Europe, D. chalybeata is the only species of Dufouria I see.
I am always surprised that the old authors all knew nigrita and occlusa, I have never seen the latter and nigrita only from tropical destinations as Mongolia.
