    Thanks jeltz, I thought that at first, however it was on the banks of a river (Derbyshire Wye), and seemed darker than I had seen before.

    I think it might be an olive upright: Rhithrogena semicolorata Peter.

    Ged, I do believe it is; have compared with info and it seems spot on. Not sure how common they are.

    Well done and thanks, Peter

    According to Maccadam & Bennett, they are fairly well distributed and common though do get mixed up with other species of the same genre. Olive Upright being the most common of them all.

    Your first sighting of it Peter so it must have been rare, but no more!

    The dark streak in visible in the femur is the give away and provides confirmation that it's an Olive Upright, (Rhithrogena semicolorata), the photograph is of a male spinner. The Olive Upright is one of only two species of Rhithrogena in the UK; the other is the March Brown (Rhithrogena germanica).
