Moscow region, 31 aug. I didn't collect this large (at least 5mm or more) fly. Upper part of face looks gren but not shining. I think it is female of another that H. bipunctatus species. Help, please, if possible. Nikita Vikhrev attached the following image:  [59.18Kb] Nikita Vikhrev - Zool Museum of Moscow University |

Let's see: * Haltere partially darkened (not all-yellow or all-black) * Lower face brown, upper face green but not glossy * Spots on wing * Hairs on fore coxa pale yellow * Legs with short hair (the long-haired species are mostly arctic so finding one in Moskow is unlikely) Kahis |
