Hello,
I photographed this fly in Northern Germany at the beginning of June. She sat on tree gum.
Is it possible to identify the genus or even the species?

Thanks and best wishes,
Frank

Hello Frank,

the genus is Ferdinandea (Syrphidae).

---

I think this should be Ferdinandea cuprea.

Greetings,

Thank you very much Jürgen and Henrik!

Hello FrankH,

Yes, a more common Syrphidae found on tree wounds and an excellent photo. What is far more rare and exciting is the small black fly in the background. The eye has a eye fascia which is coloured and the face has a light horizontal stripe: Aulacigastridae!
Do you have a photo of that specimen? What I know of these flies is that they frequent sap runs on deciduous trees. Is this a confirous tree with resin or truly a Eucalyptus like tree with gum? Do you perchance know the species of tree?

Kind regards,

Ectemnius

Hello Ectemnius,

thank you for your message!
Unfortunately I did not take pictures of the little fly in the background.
But at the same tree wound I was able to take pictures of hornets (Vespa crabro) and stag beetles (Lucanus cervus), which eats the juice also.
The tree juice comes from an oak (Quercus robur).

Kind regards,
Frank

Ah, that's a shame., but Aulacigaster (the three European species that is) are known from deciduous trees like Oak.
