Hi,
Unfortunately I am unable to identify this little one from last Sunday, feeding on Solidago canadensis in south-eastern Berlin. It measured just a few millimeters and had distinctly shadowed crossveins, a bit less visible sometimes due to flashlight. These are the best pictures I got. I thought of a Coenosia species because of size and 3 postsutural dc. Help is greatly appreciated!
Thanks, Sundew

Ah - the anal vein, though hardly visible, seems to reach the wing margin, so an Antho indeed... These little guys trick me again and again, this one's habitus looked really muscid-ish to me. - Luckily, Joke van Erkelens' great paper "Anthomyiidae voor Dummies" (https://www.dipte...ummies.pdf) says about Anthomyia liturata: "The only species within the Anthomyiidae that has the transverse veins clearly darkened so is easy to recognise from that". So we got a name at last! Thanks, John.

There is another species to be considered: Anthomyia confusanea. I believe that the difference is in the number of anterodorsals on tibia 2.

And once again, things are getting crazy... But that's the exciting thing about fly observation. So we learn from https://diptera.i...d_id=76397 and https://diptera.i...d_id=15557 that - either generally or at least in most cases - A. confusanea has midtibia with 1 ad and hind tibia with a bit of orange colour, and A. liturata has midtibia with 2 ad and black legs. Best differences are in male genitalia, and A. liturata is more common.
That's all fine but difficult to apply to my photos. I think there are 2 ad of different length. The legs look black, though I also have a picture (not shown here) where the hindlegs appear reddish. I think that is a reflection from the flash. A. confusanea has not yet been confirmed in our region of Berlin/Brandenburg. So it remains A. cf. liturata. Thanks for the interesting hint!
