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.
