    $\begingroup$ Might be Episyrphus. In any case, the common name for the family is "Hoverfly". $\endgroup$ – Karl Kjer Jan 6 '18 at 12:25

    $\begingroup$ @KarlKjer After consulting Wikipedia, I tend to agree. Furthermore, I am amazed to see that this kind of eyes apparently makes it a female! en.m.wikipedia.org/wiki/Episyrphus_balteatus $\endgroup$ – Ludi Jan 6 '18 at 15:09

Insect ID from photos is difficult, but this is definitely in Syrphidae. The alternating thick and thin stripes on the abdomen resemble very much those in a picture I found here: https://alchetron.com/Episyrphus-balteatus I would say that it is likely in the genus, Episyrphus, which is present in Austria.

  • $\begingroup$ Syrphidae are usually easily identified from photo. This is without a doubt E. balteatus. There is no other species that resembles it in Europe. $\endgroup$ – RHA Jan 7 '18 at 3:12
  • $\begingroup$ Could you provide further support using Comstock-Needham system out of curiosity? $\endgroup$ – theforestecologist Jan 16 '18 at 4:00
