Hello,
when I first saw this furry fly today at a forest path (northwest Germany), I thought it was a bumblebee, more precisely
Bombus pratorum. But only the males of this species are so furry, and they aren't there, yet. On closer looking I saw, it was a large fly, but none of the bumblebee mimicking Syrphidae.
I think, this must be an Oestrid, possibly
Cephenemyia stimulator.
Fittingly I also saw some roe deers at the same time and place in the forest...

Hi Juergen , vey nice indeed, but it is a Syrphid:
Mallota fuciformis.
Excellent find !
( Cephenemyia are strictly summer species)

Hello Theo,
thank you!
Now it makes sense, that the fly moved into the gap in the tree. Maybe there was a sap flow. I already wondered about this, but did not find an explanation.

You actually observed that ? Great !
The larvae live in rotholes (not sap flows)
Greetings

Not really. The hole was too dark to see anything from the distance. When I climbed the slope to get to it, the fly came flown out of it and was gone...
