The aim of this blog is to connect fly-tyers all over the world, to share, techniques, patterns, information and knowledge.



I am currently catching and photographing mayfly’s in the studio, this is one from today that I believe is a ‘Lake olive Dun’ although I am not 100% sure, if you think otherwise I would like to know what it is. I will be posting images of different mayfly’s every couple of days now and need help identifying them, so please help! I hope you like the coming photos. Have a great sunday…

    Hi Barry,

    The two tails and absence of hindwings narrows it down to 3 possibilities (Pond Olive, Lake Olive or Pale Evening Dun). The distinctive browninsh-yellow leading edge to the forewings is characteristic of the female sub-imago (dun) of the Pond Olive (Cloeon dipterum).

    Regards, Dave
