Thread subject: Diptera.info :: Cylindromyia auriceps?

Here are two specimen I collected at the same place (nutrient-poor grassland in the very east of Niedersachsen, Germany, Landkreis Lüneburg).
Using Tschorsning & Herting (2005), I end up with C. auriceps, though I'm unsure about some features.
The first one is from 20th August 2021.

The second one (21st August 2021) lokks a little different, but I come to the same conclusion.

Yes, Jan that is auriceps.
It is common in eastern Europe, but getting rare to the west. No confirmed records from either NL or B. So Luneburg is promising !

So this is the 2nd and 3rd record for Niedersachsen :)
