Fly pathogenic fungus (Entomophthora muscae)

This small but attractive little fly with metalic blue colours has furry white bands between the tergites.
Found dead on a log cabin wall in a local nature reserve.
"The mycelium of this fungus may grow into an area of the brain that controls the behaviour of the fly, forcing it to land on a surface and crawl upwards. The hyphae gradually grow through the whole of the body, digesting the guts, and the fly dies in about five to seven days. When it is critically ill, it tends to crawl to a high point, straighten its hind legs and open its wings, a behaviour that ensures that the fungal spores are dispersed as widely as possible." - Wikipedia

Sorry for the poor picture but the story is great. Nature is amazing.
