Hello, this about 2 mm small midge was found on Sept. 3, 2020 east of Hannover, Germany on Tanacetum near a railway track. Is it possibly Ozirhincus tanaceti? Many thanks in advance! Hans Haleun attached the following image:  [105.64Kb] Edited by Haleun on 20-03-2021 16:53 |

There are two species on Tanacetum: Ozirhincus hungaricus has 11-12 flagellomeres Ozirhincus longicollis (= tanaceti) has 10 flagellomeres Both species are found in Germany. https://doi.org/1...ne.0130981 |

Dear John, thank you again for your great help! I tend to "see" 10 flagellomeres, those are marked in my 300 %-view. If you have no objection I call it O. longicollis. My best regards! Hans Haleun attached the following image:  [58.79Kb] Edited by Haleun on 20-03-2021 16:52 |
