I do not mean the spider nor the fly, look at the larva at the bottom. Crab spider catch only fresh, moving flies so it is not a saprophagouds larva, maybe a parasite living the host like rats leaving a ship that is sinking?

I'm not aware of any cylclorrhaphous larvae that parasitise adult calypterates, so my guess is that the calliphorid prey had some "ready-to-lay" maggots which have deserted the sinking mother-ship. Whatever is happening, it's an interesting photo!

Does someone has a scan of Nartshuk E.P. 2003. Key to families of Diptera (Insecta) of the fauna of Russian and adjacent countries. Proceedings of the Zoological Institute Vol. 294: 1-252 for me?
