Hello together,

I found this fly on 21. April 2021 in Southwest Germany, Baden-Württemberg on a dry meadow. Is ist Systoechus ctenopterus?

Greetings Siggi

Hi Siggi, I fear it is not: vein R-M is not close to the base of the discal cell. So it should be one of these:
Bombylius cinerascens, minor or posticus
Do you have more photos of the specimen? Lateral? We need to see the femora as well as a side of the thorax.

Hi Eric,

I'm sorry, but I only have this one picture. Thank you for your detailed explanation. Then I will take the picture under Bombylius sp. classify.

Greetings, Siggi

Could be Bombylius venosus male, but not sure.

Hi Xespok,

please excuse my late reaction. I had somehow forgotten that. That could fit really well. I will now mark the image with a "cf." label. Thank you very much.

Greetings Siggi
