  1. This is not Chrysotoxum festivum, Jivko. Although the pattern of the abdomen is very similar, the shape and position of the eyes and antennae is not the same and it doesn't have black spots on the wings.

  2. I am not convinced that this is not C. festivum. Shall make further research.

    1. I am not sure how relevant it is but this is the difference in the position of the eyes I was reffering to. Both specimens are identified as C. festivum.

      Here is a compilation of several species which are very similar. One of the differences is the lenght of the segments of the antennae. Also the colour of the legs down to the base.

      1. @WildFlower, I think the main difference is the lack of the darker spots on the wings. In this case the position of the eyes is sex dimorphism: females are with separate eyes.
        Checking different sources I came to the conclusion that most probably this is Chrysotoxum verralli
