When I was a child, my interest was attracted by dead flies sticking to a window pane with a cloud of white powder around them (the fungus spores). That was a quite frequent phenomenon. Later I watched infested flies, the last walk of which had led to a position high up on a grass leaf or stalk. This behaviour is apparently induced by the fungus. When I was going to photograph a killed Scatophaga with monstrous abdominal swelling a wasp came and grabbed the expected "easy prey". As the fly stuck to the stalk the wasp left with its head only but was surely contaminated with spores thereby. Now I wonder if the fungus might do harm also to a wasp, but I have no reliable information. Dou you know more?
