Thread subject: Diptera.info :: Scaeva, but which one? -> Scaeva cf. dignota

Hi all!

Kormann leads me to Scaeva selenitica, but comparing pictures with the gallery here shows much more similarity with Scaeva dignota.

Does S. dignota occur in Germany at all? The gallery pic is from Spain.

Approx. 12-15 mm

16.7.2022, Germany, Upper Bavaria, above Thoraualm at Mt. Hochfelln, ~1350 m asl, coordinates approx. 47.7554, 12.5634

Hi Rupert, I'm quite sure it's S. dignota as the yellow stripes significantly reach the side seam on the abdomen.
And according to FE it's found in Germany, too.

Thanks Eric for ID including explanation!

I don't know what "FE" is, but I know I will have to check if I have some misnamed Scaevas on my HDD...

FE should be Fauna Europaea: https://fauna-eu....

Thanks Jan!
No chance to successfully google "FE".

Yes, that's what I meant.

I would be a little more cautious with the identification, as I find the hairs on the eyes a bit long. To tell the females apart from S. selenitica is difficult - see the character table in https://www.resea...Poland.pdf. S. selenitica specimens that developed at warmer temperatures may have spots that reach the tergite margins. So to me it's just S. cf. ignota.
