... and a lowland twin of #2? Should be very common ... and easy to identify? Best regards Frank Germany / NRW: Bornheim, V.2006

It's a muscid of the huge Helina-Phaonia-Mydeaea-group.

Frank I wish I'd thought of describing this identification problem in the same neat way Kahis has . The keys to the genera of Muscidae rely on tiny characters such as setae on the radio-cubital node of the wing or details of chaetotaxy not visible in photographs of living flies . The species though in different genera often look almost identical especially in Helina-Phaonia-Mydeaea .Specimens are essential in these taxa (with a few possible exceptions). Robert |

Thanks! I understand, but I don?t believe  There is no #1 common fly on the trunk of our cherry tree? Hundreds of "identical" flies in our garden belong to various species? the original photos (2160x1440) don?t help? I have to delete the half of my photo collection? Ok, I have to delete only 49%, because this specimen was collected. Best regards Frank |

This is the theoretical position. In practise a best guess is likely to be correct. It is a question of who will guess. We need a team I think. Best regards  Robert. |

This is a group with too many common species  I think it is a Phaonia. To be sure we'd need a pic showing the bristles on hind tibia.

This and other adjacent pictures in my gallery might show the same or very similar fly. This fly is superabundant in Hungary in broad leaved forests, sometimes hundreds are sitting on a tree trunk early in the year. These flies are small, around 5 mm, I always considered these to be Anthomyiids. This and the adjacent image in my gallery show the female of the same species. Kahis, can you confirm that these images show a Muscid? Is it not possible to guess further given that this species is one of the most common species in Central Europe. |

Thanks all! @Kahis, unfortunally there are allways shadows on the hind legs. This is the best cutout I can offer:  Perhaps some more details can be seen on this shots:   ???

Your second set of photos shows a different species: Muscina levida (Muscidae). The combination of a yellow tip of scutellum and a smoothly bent wein (R4+5) in the apical half of the wing is typical for this genus. Edit: The last photo in your recent message is Muscina. The middle ones may or may not be the same species as the first. Edited by Kahis on 27-10-2006 20:53 Kahis |

Thanks again and thanks @Kahis for the name! Then picture #1 and #3 (portrait) belong to the same species. I have two pics of Muscina levida with a 10 seconds time interval. 3 minutes later a took a series of the unknown species. Unfortunately I used my camera a few minutes later again - same trunk, same species?:  Sorry for this chaos and wasting your time Frank PS. All other grey ufos were just deleted, so this one is the last one - of this day.
