From my observations this year, the males of Bibio johannis seems to be more common in the meadow and Bibio lanigerus seems to be more common in the forest Renko attached the following image: [234.79Kb] Edited by Renko on 19-04-2021 08:13

With this post it seems that my female seems to lead towards varipes rather than lanigerus but I never saw a single male Bibio varipes (yet) in more than 6 years... that where I understand the current difficulties with the females of Bibio johannis/lanigerus/varipes without at least a pairing with a male So I will register this female as Bibio johannis/lanigerus/varipes Thanks you so much, Theo !
