Thread subject: Diptera.info :: Tachinidae? with red eyes

This fly looked (to my untrained eyes) like a small, slim Sarcophaga sp. at first, but I don't think the wing veins are quite right and it's maybe bristlier on the abdomen and behind the eyes, so I'm thinking Tachinidae... but I need expert help on this as per...

Another view, a different individual with maybe less white on the abdomen, but the same species i think:

This is family Sarcophagidae. Probably Sarcophaga species.

OK, thanks, I'm sure you're right, and that's what I thougt originally, but checking other pics i have of Sarcopahaga sp. the wing veins seemed more "kinked" in those as in the next 2 pics, and had a more black and white checkerboard look to the abdomen but maybe the flies I posted yesterday are of a different Sarcophaga sp. and the look of the veins and abdomen varies?

Wing veins of the flies posted yesterday which i thought might be tachinids, but you confirm are Sarcophaga sp... but which seem less kinked to me, unless it's just the angle of view.

Thing is, wing venation is slightly variable and I suspect that your first specimen isn't a Sarcophaga s.s. .. more Sarcophaga s.l., which would explain the difference ;)

Anyway, your first thought was correct - it is "a small, slim Sarcophaga sp." but probably one of the other sub-genera - not Sarcophaga (Sarcophaga) :)

OK thanks Chris, your comments make good sense. I'm pretty sure these were much smaller than the Sarcophaga sp. I'm used to, but being a tricky group, I doubt I'll get any closer to an ID.
