Hi I found today this fly in a dry wasteland. I think it is a Tephritis, but I'm not sure of the species. I mainly hesitate between T. neesii and T. separata, but T. divisa is close too. What are the best criteria to identify these species ? I don't know the host plant but it is possible that both Leucanthemum and Picris are present. Found in Bobigny, Seine-Saint-Denis, Île-de-France, France 20th of July 2020 size : around 5 mm Axel D attached the following image:  [125.23Kb] Edited by Axel D on 24-07-2020 21:26 |

It is not Tephritis neesii, because there are no long white hairs on the base of the oviscape. Tephritis divisa has only two hyaline spots in cell R1, your fly has three, so that would leave us with Tephritis separata. https://diptera.info/forum/viewthread.php?forum_id=5&thread_id=83423 Ben |

Thank you for your clear answer.  I read sometinhg about hairs for neesii but I did not undertand. Now it's clear for me. I noticed the number of spots for divisa but I was not sure it was a good criterion. |
