Entomophthora fungus

I found this dead fly stuck to a classroom window at Ackworth School. Looking closely, I could see what looked like fungal hyphae extending from its feet, attaching it to the window. I believe that it has been killed by an Entomophthora fungus – possibly Entomophthora muscae.. 

The Entomophthora fungus affects the nervous system of a fly and forces it to climb upwards to a prominent position to die in order that that the spores are more easily carried away by the wind. Here it is possible to see that the fly is surrounded by fungal spores that are ready to infect other flies.
