Yes, what is this little fly (tachinidae?) doing, on this bee trapped by a spider?

Looking for some food. It is a specimen of
Desmopetopa (Milichiidae) and they have an uncanny sense of smell to locate dead honeybees on which they can be found feeding. As a rule these bees are captured by predatory insects (Asilidae, Reduviidae, etc.) or spiders (either in webs or, like this one, by crab spiders).

Hallo everyone! A new question on same topic.
These are the Milichiidae in Sweden:
Sprickflugor Milichiidae
Leptometopa latipes (Meigen, 1830)
Madiza glabra Fallén, 1820
Milichia ludens (Wahlberg, 1847)
Neophyllomyza acyglossa (Villeneuve, 1920)
Phyllomyza securicornis Fallén, 1823
Desmopetopa I can´t find. Of what specimen is my fly?

The image does not really allow ID of the specimen. Being on the spider prey and the black colour make it practically 100% certain that it is Milichiidae, but genus is impossible. Other genera than just
Desmometopa can be found on spider preys:
