The sequel: this might be the same fly, but I'm not sure.

Who's this then?

And what the :p:oB) is he (or she) doing??



Thanks again!

I'm not sure what species of fly this is, but the pose is typical of a fly with a parasitic fungus infection - Entomopthora muscae is the usual name, but there may be other species involved. The fungus induces a change in the fly's behaviour, so that it dies in this pose, and the fungal spores are easily dispersed when the abdomen ruptures.

Hi Tony,

Thanks for the information. I've seen this fungus (or another kind) at work before (or at least the result of it's work), resulting in flies covered in a dust- or yeastlike powder and all flies were situated in shrubtops. As if they were programmed to climb to the top.

Are there many different fungi like this around? And if so, has every fungus a specific host?

Thanks again!
