Hi, found this male in my garden (Middle Franconia near deciduous forest) on 20190703 and I cannot find a similar one with "wasp waist"...
Any help is highly appreciated!

Thanks, Eric

Thank you very much, clovis!
Have you ever seen a similar deformation of the abdomen? Is it perhaps caused by a parsitoid?

Regards, Eric
