Flensburg, N.Germany, 15th August 2018, drought.

Found this dead fly (is it Drosophilidae), with raised wings, stuck to near the top of my kitchen window. On either side, opposite it's abdomen is a fan of white speckles, almost 2cm long on one side and about a cm on the other side. They appear to have been blown out of the fly. Am I correct in assuming that these specks are the spoor of Entomophthora muscae which infected and killed the host?

Thanks in advance
Ray

As concerns the fly, it belongs to Drosophila melanogaster group. The fungus belongs indeed to Entomophthorales, but I would be cautious in species determination; there are about three hundred of described species, most of them parasitizing insects, apparently there is not only one on Diptera.
A mycologist, or mycological literature, could give you muh more of interesting information.
