All right, My buddy handed me this fly recently. It is store bought, but he can't remember what fly shop or where. You can see in the pix that it is a bit worse for wear. I nymphed it very successfully. It was the upper fly of a two fly rig. this is my last one and I want to tie more. I might be able to figure it out, but I'm hoping someone can identify it and pass on the perfect recipe. It is tiny, the one in the picture is a #20 I'm pretty sure - check out those pretty mono eyes! The wings on the side flare out then curve back to hook - I'm not sure if they act as wing pads of the pupa or if they represent a thorax... hmmm. Any guesses?
