The Lil’ Grey Nymph: I have posted before re this simple fly I came up with (I didn’t want to say ‘designed’) several years ago. I want to point to it again because several times, this past Summer, it was so productive I had to grin and shake my head given the flies simplicity. You can mix up the body color and ribbing color, but keep it sparse and smallish (14-18). Don’t fret over the bushy tail, although it can be trimmed to fewer fibers. Give it a try and let me know if you have success with it.
