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 Sundew attached the following image:  [239.1Kb] Edited by Sundew on 19-08-2025 21:54 |

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. James |

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! Edited by Sundew on 19-08-2025 21:50 |
