Hello,
This is my first query to Diptera.info.
I took this picture on 13th of May 2019 i Leudelange (Luxembourg). It was sitting on top of a blue paper recycling bin. Can anyone tell me which kind it is?
I hope I have done everything correctly. If not I will be grateful if anyone can tell me how to do better.
Best regards
Roger
