A nice looking mayfly emerger-nymph pattern. A good beginner’s pattern and of course you could buy it via MF&PD Flies. If you should decide to tie it, the CDC hackle wraps should not be over done or dressed with any floatant.
Gold bead for head, black tying thread, hackle fiber tail, mylar, gold or silver ribbing, pheasant tail fibers wrapped for the body. A CDC plume tied in at tip and wrapped forward…tied off behind bead. Size hook could vary from a size 10 to a size 14 (you could go smaller by realistically the size of the CDC plume would dictate hook size because you do not want the individual CDC fibers to extend back beyond the bend of the hook.
