Hi! Although these flies behave like many like Dolies and to a degrees also look like them, they belong to genus Ephydra (Ephydridae) or possibly one of the closely related genera. |

Thank you! So both Dolichopodidae and Ephydridae may act as Gerridae-fly! Nikita Vikhrev - Zool Museum of Moscow University |

Identified by Marina Krivosheina as Coenia palustris. You agree or not, Jere? Nikita Vikhrev - Zool Museum of Moscow University |

Hi. I have to disagree! Coenosia should have three postsutural dc setae (+ one presutural); your photo clearly shows 1+4 dc. Coenia palustris is a very common species and I have plenty of reference material in my own collection. The habitus is very close, but C. palustris has brown dusting on thorax & a darkened haltere. Hmm hmm feels weird going against the word of a well-known group specialist. I've met her a few years ago in Helsinki and she kindly checked some of my own specimens, including some C. palustris.

Than, next week I ask her once more and put your reasons. Identification by photo is a very special kind of sport and you are master of this sport. May be (even probably) she is not. Anyway we'll find right answer (or proove that it exist several possible answers). Thank you Jere. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Jere, fortunely everything is clear. In Moscow Zoology Musem Krivosheina, Shatalkin and Ozerov ask somebody put all identification for me in one fail, and somebody wrote Coenia palustris instead of correct Setacera sp., which is "one of the closely related to Ephydra genera". Thank you. Nikita Nikita Vikhrev - Zool Museum of Moscow University |
