Last summer I took these pictures of a member of the Syrphidae on my balcony (Switzerland, Geneva area, Alt. ~380m, June 2020 @19:14)

Pictures:

Scaeva sp.-1 Scaeva sp.-2 Scaeva sp.-3 Scaeva sp.-4 Scaeva sp.-5 Scaeva sp.-6 Scaeva sp.-7 Scaeva sp.-8

I hesitate between three species but it could also be another one:

  • Scaeva dignota
  • Scaeva selenitica
  • Scaeva pyrastri

Because the pale marks on tergites 3 and 4 seems parallel to the anterior margins of the tergites, I would eliminate the third one, especially because the marks are also more yellowish than white. For the two other species, I am not sure because I checked many pictures on the internet, but some are wrongly tagged (google images results).

Any entomologist can confirm the exact species of this hoverfly?

  • $\begingroup$ Awsome pictures, we have them in Austria too ;) Personally I tend to the 'Scaeva selenitica', but that's just my uneducated guess.. $\endgroup$
