Is it possible to identify this female Orfelia. I thought it might me O. discoloria, but I'd prefer to check the male genetalia. I found it on the 23th of September 2017 in a forest near Ede, the Netherlands.   Thank you! Edited by Bas on 11-02-2018 21:46 |

Based on wing length I suspect it is Macrocera...

Thank you Paul! I don't have a key for Macrocera species. Which details should I photograph to come to a species? |

I made a clearer photo of the wing: I'd say that macrotrichia are present (especially on the veins, not really clear in the photo), no distinct marking on the wing and R1 without blackish mark just before tip, so I'd think it's M. stigmoides. Agreed? |

Pssibly, but of course I cannot judge the trichia on the wing. I should say that the antennae seem a tad short for stigmoides but that could be a result of orientation or damage.

I dont see any macrotrichia on wing membrane in your photo. They should look like here: http://www.spessart-fliegen.de/diptera/keroplatidae/macrocera/macrocera_stigmoides/wing.html |

Thank you Jan! I thought the macrotrichia could be present on the veins as well. I went trough the key again and based on the three stripes on the mesonotum and the black bristles, I'd call it M. vittata. |
