Hello,

Saw quite a few dead specimens of this fly hanging on grassleaves and fences. A closer look gives me the idea they dead of some sort of disease. Is that indeed the case?

Hi Andre.
I'd say male Phaonia (errans?) and fungi.

Wow,

Nikita. And I always thougth Moscow was a long way away. Your quick!
Do you also know why quite a few of them get it at the same time? Is it contagious? And why they all died hanging on their snout?

Thanks,

Andr

It is only my thoughts, but I think that fungi origine desease is approxmately same as Saprolegia of aquarium fishes; when conditions become bad (in case of fish too cold, in case of fly may be too cold and wet) this parasitic fungi bacome to grow.

I think this type of fungi is called Entomophorales.

Nikita is on holiday in Turkey. He should be outside catching flies! Pfft

This fungus is Entomophthora muscae. There is quite a good account of it at http://botit.bota...r2000.html.
It attacks many species of flies, notably Scathophaga, muscids and smaller hoverflies like Melanostoma.
This unfortunate fly is Phaonia turguriorum.

Hi Tony,

I,ve read the article and feel sorry even more for the poor flies that unwantedly pick up one of those spores. Hope they don't suffer too much.
Thanks again,

Andr
