Northern Germany, Schleswig-Holstein, Halstenbek near Hamburg, area of tree nursery, small earthwall (overgrown with small bushes like hazel, maple, roses, sloes, brambles) under big oaks, length of the fly: 7,0 mm; found at a leaf of Prunus padus, 31th of May 2022 (Outside photos: Kuv).
Checking the Diptera Gallery I think the picture of Pipizella virens looks like "my" fly (s. https://diptera.i...to_id=5691). Is my idea ok? Please help to get the ID.
Greeting Kuv

Hi,

Pipizella is only safely identified by examination of the male genitalia. It's the best to note it as Pipizella spec. If you collected it and extracted the genitalia, ID to species level is possible.

Best, Jonne

Hi Jonne,
thank you very much for your answer. I had been afraid to read such result, but it's - of course - ok!
Greetings Kuv

In Denmark, only viduata and virens have been recorded so far. This one is not virens, since the hairs on the hind tibia are too short. It could be viduata, but whether other spp. with simitar appearance are found around Hamburg I don't know. https://www.flickr.com/photos/63075200@N07/collections/72157631706765825/

Thank you very much Karsten Smile. Yes, I agree, it could be P. viduata but I cannot rule out other hoverflies for the region Hamburg. So I'll change headline in: "perhaps P. viduata".
