Berlin - August 2017 - grassland I think that Agromyzidae is correct but I have no particular reason for selecting Ophiomyia other than appearance. I am looking for confirmation of the genus. I have microscopic photos if species level can be reached. I will post as necessary. I am thinking Ophiomyia nasuta... Also, I would like to know if any keys exist for Palearctic species. Is there an expert around in the forums? Thank You for your Time and Effort. I appreciate the help. johnes81 attached the following image: ![]() [70.84Kb] Edited by johnes81 on 11-09-2017 00:47 John and Nini. Naturalists not experts. |

Milichiidae, maybe Desmometopa.

Dear Stephane, you never cease to amaze me ![]() Myself, on the other hand, I have a lot of studying to do. I thought that it was Agromyzidae. Thank You so very much. I hope to help you with something in return someday. This is a very interesting fly, so I want to read more about it. Unfortunately, this one is a female. I had trouble dissecting the very tiny ovipositor. I will try to find a male specimen. John and Nini. Naturalists not experts. |

I saw a thread here: https://diptera.info/forum/viewthread.php?forum_id=5&thread_id=47176 the mid- and hind tarsi of this species are yellowish color. So could this be Desmometopa varipalpis? I can show the legs but I need to collect the photos. I'll post more data... John and Nini. Naturalists not experts. |

After many hours of research and a male specimen, my Wife and I conclude that this species is Desmometopa m-nigrum based upon the work of Sabrosky 1983. Some of the details are off a bit but overall it is a match. I had to dissect the very tiny palpi (unbelievably difficult to me.) I also dissected the male genitalia. I cannot find a better match for this than m-nigrum. Thank You Stephane. John and Nini. Naturalists not experts. |
