Hello, is it possible to get an ID for this Phaonia? Sighted on 18.05.2025 in Germany, North Rhine-Westphalia in the garden. Body-size approximately 6 to 7 mm Thank you. Bernd fatsemann attached the following image:  [62.49Kb] Edited by fatsemann on 18-11-2025 22:45 |

The images are quite blurry - hard to make an ID or even a serious guess unfortunately. But anyhow I guess it could be the female Phaonia fuscata which I've never seen before. - legs predominantly yellow - crossveins significantly infuscated (but not a P. tuguriorum!) - antennal base black - arista long plumose? - parafacial with a transverse black spot near the insertion of the antenna at #3??? Greetings, Eric |

Hi Eric, thanks for your effort and your assessment. The arista has long plumose. Sorry, I don't understand the last question. I don't know what you mean. On observation.org, depending on the pictures, you get anywhere from 100% Phaonia fuscata to 100% Phaonia tuguriorum. I'll classify the fly as Phaonia cf. fuscata.

P. tuguriorum and P. fuscata have 2 main differences when seen from above: P. fuscata has 3 DCs whereas P. tuguriorum has 4 Dcs / P. tuguriorum has a pale brown tip to the scutellum whereas P. fuscata has a fairly uniformly coloured scutellum. Observation.org can be good for some species but I would be very careful with many of their ID suggestions. Even if it says 100%, treat that as a starting point for further detailed research of your own. James |

Hi James, thanks for your explanation. I'm not an expert. What are DCs and where can I find them? Greetings Bernd |
