Wasp-like syrphid visiting bindweed flowers on a sunny margin at the base of the renatured old mining dump at Landweiler-Reden (Saarland, Germany) on 18 June 2022. Size about 13 to 15 mm. Obviously one of the Chrysotoxum species, which are rather difficult to separate. I would suggest Chrysotoxum cautum (relative length of the antennal segments, shape and amount of yellow markings on the abdomen). Can this be confirmed? I have slightly rephrased the question, added another picture and am looking forward to your opinion.
