 Hi,
this fly I saw on August 3rd, 2017 in the northern foothills of Vienna. It was about 5mm long, maybe shorter. I have not been able to identify it and would appreciate your help.
Best regards,
Konrad

 I have not met every diptera in Europe, so I could be very wrong:
I think that the orange color is a result of reflection of light from the wings.

as for the fly, I have no idea which family.
eventually, some of the more knowledgeable members will have a look.
you may have to wait a few days...

 Thanks, John and Nini,
I have also considered the possibility of a reflection, but a member in another forum mentioned that he had seen other specimen of this fly that looked just like it - so even if it was a reflection, it would be characteristic.
Best regards,
Konrad

 I'm adding a more closeup section of my photo which may show more detail in better quality.
Best regards,

 This fly is one of the Platypezidae. Yes the colours are reflective colours off the wing

I will try to fix the messages this month. We have to make some other configuration changes before software goes out of support at end of year.
