Berlin - July 2018 Hello everyone, I've noticed a photo of mine that might depict a male of O. petrei. If i remember correctly, the abdomen is paler than germinationis. Thus, could this be O. petrei? Best wishes, John johnes81 attached the following image:  [68.5Kb] Edited by johnes81 on 06-01-2020 13:05 John and Nini. Naturalists not experts. |

Hello Libor, Thank you for replying. I am still looking through photos and i noticed this series of photos. I've been wanting to post since last year but i've been too busy. I'm trying to get through more photos before my shoulder operation in a week. Anyway, I notice that petrei male is missing from the gallery. It would be nice to have some photos, so i will put somehing together for the gallery... Best wishes, John John and Nini. Naturalists not experts. |

Hello John, Very late response: It's always a bit tricky because I have also seen specimens of Opomyza germinationis with a rather "petrei-like" abdomen. In those cases you see the stripes along the sides of the abdomen, but the area next to that stripe is not that convincingly orange/reddish. In your picture is looks rather orange/reddish, but in the smaller picture it isn't that convincingly orange/reddish. For me the best I could make of this is Opomyza cf. petrei. Presence (O. petrei) or absence (O. germinationis) of hairs on the proepisternum should tell which species you are dealing with (not visible in the photos). Jan Willem van Zuijlen |
