Please, can you help my to identify this fly? I suppose, it is Tehreva, but I don't know much about Diptera. Date: 28.05.2017. Localization: Poland, Mazovia, near Warsaw. I found this fly on the humid soil. mantiss111 attached the following image:  [263.26Kb] |

Are you sure? How can I tell the difference between A. annulata and other flies belonging to the family Therevidae? |

Of course I'm not sure, it was merely a suggestion going on how it looked in comparison.But a quick look on the interwebz told me it can only be identified by checking the male genitalia [thanks to Theo Zeegers in this thread] https://diptera.i...d_id=80420 Sometimes suggestions don't get a reply.. https://diptera.i...pid=238465 So maybe some expert might reply in this case. Regards Roger |

The white 'Thereva' in which females lack calli have been split off into other genera, like Acrosathe. annulata is the only one in Central Europe, though eventually baltica might turn up on the Pomorze coast. Check www.fauna-eu.org Theo |
