Hi!
What species are these? are they even the same species? Males lack the dark final tergites of phalerata, but the abdominal patterns do not oviously match anything I can see. They are also very brown for quinaria group.
I could guess at any of unispina or transversa (too dark!, not spotty enought), or limbata or kuntzei? Or something else. I really think they do not match https://diptera.info/forum/viewthread.php?thread_id=102445, which I thought were limbata or kuntzei (those were lab reared, so pale)
All these flies collected from the same courgette plants in Sussex, UK. Scale marks are 0.5mm.
Thanks!
Darren

And here are some more males, collected the same time and place, that may or may not be the same species.

Difficult to tell. i think it may be phalerata, just because it is very variable (but note the width of pale dorsomedial line of abdomen for possible limbata). The two upper males of the series of five may be kuntzei. Terminalia of both sexes should be studied, mainly the oviscapt of phalerata is quite characteristic.
