But I have no idea about closer id. 23.09.2007, northern Poland, size ~5 mm. alon attached the following image: [75.88Kb] Edited by alon on 18-10-2008 13:09

The last photo shows the swollen abdomen, with the sclerotized tergites looking rather small because of the swollen membrane; it is a pregnant female, possibly with 1st instar larvae, as Emmesomyia have oviviporous larvae. The darker shining tergite 6 is clearly visible, a characteristic of Emmesomyia, and provide a distinction between the two European species in the female, grisea with completely shining, socia with some grey dusting.
