How to tie it
Wrap 0.020 lead wire over about three-quarters of the shank, centering it on the flat part. Start the black thread, dam it in behind the wire, take it over the wire, dam it in front, then return to the tail.
Strip about 15 of the longer fibers from an olive-dyed grizzly hen feather and tie them in at the rear as a tail slightly longer than a hook gap. Save the rest of that feather for the collar.
Use the fluff from the base of that feather to fill the step between the bare shank and the front of the lead, then trim the butts.
Tie in the fine gold or copper wire just behind the lead wraps with two or three turns.
Snip the brittle inch off three strands of peacock herl and tie them in at the tail. Leave the thread hanging halfway up the shank, as you wrap the herl forward side by side (not twisted into a rope) you can push that hanging thread ahead of you to keep the strands together. Build a football-shaped body up to just in front of the lead and tie off.
Counter-wrap the fine wire forward over the herl in four to six turns purely for durability, lock it in with several tight wraps and helicopter it off.
Take the remaining olive grizzly hen feather, strip the fluff, and tie it in by the tip: pull the tip back, cut a small V-notch, tie it in concave side toward the hook with two or three wraps, fold the tip back and add one or two more, then trim.
Take three turns of hen hackle as a soft hackle collar and tie off on the far side with two thread wraps, then one more, and trim close.
Sweep the hackle back, build a good-sized nymph head, whip finish with four or five turns and add a drop of head cement.
