Hello! Could this 10 mm Muscid be a Mydaea, or is it again just one of the many Phaonias? Found on Nov-27 on tree trunk (Ostwestfalen/Germany). Thanks for comments!

Hello, Nikita! Nikita Vikhrev wrote: Phaonia rufiventris/subventa, I think Arghh... I have photographed dozens of Phaonia rufiventris in the last days on tree trunks (subventa disappeared already some weeks ago), but this one seemed to me more robustly built, with bigger orange spots at the wing bases... Thank you for leading me into the right direction :-).

1. Thank you Robert. I'd wait a little bit more 2. This matter needs more light, may be Robert ask Adrian Pont, may be Tony or Kahis reply. In our Gellery comment under Phaonia rufiventris is: "The thorax is too dark to be pallida and too yellow to be subventa, so I am sure that you are right it naming it as rufiventris" Is there only this vague way to ID? As far as I understood Pont's comment it doesn't much matter 1 or 2 presutural ac are? (In case of Juergen fly - 2). Any idea? Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Muscidae are very difficult from photographs .Now I see that no thorax yellow is showing in dorsal view (see second gallery photo of rufiventris for comparison ) I wonder if this is Mydaea spinipes Karl ? though this species is smaller at 7mm.Robert P.S. Keep photographing Muscidae the more photos we see the better the ids will become, especially if we have confirmed id. |

We both posted - 15 minutes apart. The comment on the presutural ac's was mine. The Fonseca key was misleading. Adrian is in South Africa.Witing for Tony We must have a forum on the photos we have so far. More photos of correctly id'd flies would be a great help. I cannot do these myself atm but can lend pinned material det. A.C. Pont. Any offers for the photography? Robert Edited by Robert Nash on 30-11-2006 12:51 |

Hello, Robert and Nikita! Thanks for your comments! Robert Nash wrote: P.S. Keep photographing Muscidae the more photos we see the better the ids will become, especially if we have confirmed id. I take photos whenever I see them :-) - constantly hoping to get more detailed pics from more different views...
