Small male anthomyiid, 3 post dc’s, 2 pre dc’s, small acrostichals, biserial with darker central stripe, tiny scutellar apicals crossed, large sub-apicals diverging but not crossing, eyes bare, mentum stout, lightly dusted, pre-alar longer that rear notopleural (if I’ve got my bristles right), notopleuron with a few hairs well below bristles, lower squama hidden, parafacials dusted brown, arista pubescent, sternopleurals 1:2, no hairs on tergite 6, no apical av on tibia 3.
Does this add up to genus or better please?

Maybe worth considering Paregle audacula?

Check for Delia platura / florilega !

I've been thinking along those lines too. There's a lot here that reminds me of
D. platura if it weren't for the notopleural hairing.

We can see the typical row of av on the hindtibia.
Maybe Phil mistaken the hairs on top of the katepisternal for hairs on the notopleural.
So check if there are little hairs between the two notopleural bristels.
If you like, I can show it with an example......

Perhaps image 6 shows the spatulate seta on the st5 process of
D. florilega? The shape of the surstyli looks convincing.

Delia platura/florilega. Probably florilega. Need to see the dorsal surface of mid tarsomere 1 which has some long setae in florilega. This species has no hairs on notopleural area

Thank you Michael. It is entirely possible that the hairs I saw related to the pleuron below. I will check your information next chance I get.

Michael, no long hairs on any tarsomeres so presume
platura
?

Yes
Delia platura is the world's most widely spread anthomyiid. Found in all continents except Antartica. So it is probably also the world's most photographed anthomyiid.
