Oestridae? (23.04.22) --> Mallota fuciformis (Syrphidae)

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...

I already wondered about this, but did not find an explanation.

When I climbed the slope to get to it, the fly came flown out of it and was gone...
