Yellow dung fly (Scathophaga stercoraria) killed by fungus (Entomophthora muscae).

Fungi like warm damp weather... and this fly killing fungus has been having a field day; I found three dead Yellow dungflies at the top of a single thistle plant in this wings open pose they take on when infected. The fungus attacks many other flies too but dungflies seem a regular target.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

E. muscae seems to be a complex of several species, and may be OK if given as s.l. I had that link somewhere, and seem to have lost it too (and I did not change computers!).

Thanks Syrphus: I've often seen this affliction attributed to E. muscae and wondered how definite the ID could be - the s.l taxonomic fudge seems wise!
