Moscow region, 21 july, 5,5-6mm, river shore. My attempt to ID species didn't lead me to any result. May be tomorrow I'll try again with fresh brains. This white stripe on f1, can it help? If it is Lispe, of course... Nikita Vikhrev attached the following image:  [60.63Kb] Nikita Vikhrev - Zool Museum of Moscow University |

I don't think this is Lispe - looks more like Helina to me.

Thank you Tony. You are right. This fly acted as Lispe (at river silt). I compared this fly with L. consanguinea I have and didn't find hairs on pteropleuras. So, now I can ID Lispe. To ID species in Helina genus is not my ligue yet  Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Hi! The place - silt on river shore - reminded me that there are other muscid genera that Phaonia/Helina  The wing surface is barely visible, but I think there may be hairs on the upper side of the node where R2+3 and R4+5 meet, marking this fly as a probable Limnophora.

Hi Kahis, I checked this possibility after Tony's reply. I didn't find any setas niether dorsal, nor ventral on R2+3-R4+5 branch. Also it seems that Hind tibias with apical d only, without ad.

OK, I was not that sure about it myself. Just checking. Then it is either Helina or Spilogona. Mmm, Spilogona.... Now I think I know what that is: Spilogona falleni (Pont) = S. litorea auct., nec. (Fall?n). Few male muscids in this group has such broad frons, and the general shape match very well. This species is very common in the boreal zone and especially in the arctic, but it is also found in central Europe. Kahis |

Hi Nikita Fly number three is a different species. All the flies are male, but the last one has a much narrower frons. Also the thoracic pattern is different, and the chaetotaxy of the legs and head is different. I'm not certain, but I think the last one is an anthomyiid. Maybe tomorrow I will have a chance to compare named specimens to your pictures. I think that's the only way we will get an answer for you!

I had a quick look through my collection and agree with Kahis that flies 1 and 2 are probably Spilogona, though I'm not sure what species.  Number 3 looks like a Zaphne species (Anthomyiidae), and it agrees quite well with Z.caudata, but so far I only have a couple of species in this genus, so it could be something else. Keep collecting the specimens - I know the winters can be very long in Moscow, and studying the bristles of muscids and anthomyiids is a great way to pass the time!

About images 1 and 2. Today evening I found this fly in box with Anthomyiidae. Soon I found that it is Muscidae and decided that it is Limnophora (look at Kahis's comment N1). After sometime I came to Spilogona falleni (look at Kahis's comment N2). So, Spilogona falleni. Bravo, Kahis! Nikita Vikhrev - Zool Museum of Moscow University |
