I saw this beautiful fly this morning (around 8.30), still cold (12 Celsius or so), on leaves of an alder tree. Because of the stunning colors, I hope an ID may be possible. Amstelveen, The Netherlands. Footbal field lined by trees. Rather small fly, but not tiny.

I'll take a risk: male Anthomyiidae.  |

Don't think so. This one is Azelia (Muscidae)

 can you tell me how we can distinguish between Muscidae/Anthomyiidae without problems?  It is really has some jizz of Anthomyiidae. Rhinophoridae/Tachinidae give us problems but that is normal. They are very close in relationship if we can say in this way.  |

Muscidae and Anthomyiidae are also very close. There are a number of features - in most Anthomyiidae the anal vein goes all the way to the wing margin, in Muscidae it stops short. Most Anthomyiidae have crossed bristles on the frons, many Muscidae do not. There are exceptions to the rules  , so the best way to distinguish them is to get to know what all the genera look like. It is very difficult to study these groups without collecting them.
