Hello, I compare the biodiversity on an organic field with conventional farming. For that, I examined Syrphidae amongst others. The field is located in Wiesbaden-Erbenheim, Germany, at 50°03'57.1"N 8°19'04.2"E The fly referred to in this post has a wing length of approximately 5.25 mm and hair stripes on the eyes. Photos are attached. I hope somebody can help me, at least with the genus. This is the only specimen that I haven't found out anything specific about.

I couldn't post more pictures in one post so I do it here. Edit: I am sorry, it isn't working at the moment. I hope the one picture is sufficient. If more are needed, e.g. the wing or underside I will try it again. Edited by Constantin Stefan on 10-08-2020 11:39 |

Hi Constantin, I'm quite sure it's a Paragus quadrifasciatus. (If you want to add more pictures to one thread, simply click on +NEW REPLY.) Greetings, Eric |

Hi Eric, Thanks, that looks good  Are you able to confirm it 100% with more pictures?I tried like that but it didn't work. Always, when I clicked Post the picture wasn't attached. Maybe the Internet connection isn't good enough. Best Regards, Constantin |

I'm sure that more pictures would help. On the attaching: are you sure that your photos meet the requirements of the forum? No spaces in filenames, not more than 200000 bytes... See the FAQ Eric |
