A single specimen was collected around 6 p.m. by sweeping on a rather unimpressive meadow with strong marks of cows pasture near water (actually it was a big ditch beside the railroad embankment). Size approximately 3mm, unfortunately I lost it after taking some pictures. Dmitry Gavryushin attached the following image:  [81.14Kb] |

Black showed me this fly two days ago. My answer was - "I don't know, may be "Rohacek fly" = Anthomyzidae". Rohacek answered that it is not. Black send it as Opomyza. Jan keep silence. What the hell family this fly belongs to??? Nikita Vikhrev - Zool Museum of Moscow University |

Looks like Opomyza to me. Try O. nigriventris.

Hi Black, Sorry for not responding sooner! Let me say first that I agree with Tony, it must be Opomyza nigriventris. I have only once seen a specimen of this species, and that was 10 years ago. I can't remember very much about it anymore. I have searched for notes I took on this specimen, but besides the data on the labels I haven't been able to find any notes or drawings. Because I have been searching for more information, it took me some time before I responded. For as far as I know, this species is only know from Estonia, Finland, and Russia. Only very few specimens are known of this species! So I would say, please visit this location more often and try to find it again  .The bionomics of this species are still unknown. And Nikita, I have to admit that this species does indeed look rather anthomyzid like. Besides, Anthomyzidae and Opomyzidae are sistergroups.

Many thanks for your confirmation Jan Willem - I'm impressed, going to visit that place tomorrow, maybe I'll have more luck with it  .2 Nikita: sorry, my kitchen has undergone some minor renovations, and the women have swept the dust (almost) everywhere, and there's not too many places to hide, so it's apparently gone for good  . |

Extensive sweeping at this location on next week-end gave no results . |
