Make several wraps of small lead wire as shown. Secure it with several wraps of thread, creating a taper on both ends. This will make it easier to create a smooth, tapered body.
Tie in the pheasant tail fibers for the tails, trim the butt ends. Tie in the medium copper wire.
Tie in pheasant tail fibers for the abdomen so that they are facing back as shown. Wind the thread forward.
Grab the bunch of pheasant tail fibers and wind them all forward to create the abdomen. With enough fibers, the
wraps shouldn’t really overlap. Trim the butt ends.
Tie in the pheasant tail fibers that will eventually be the legs. Tri to tie them onto the top of the hook shank, not the sides. Trim the butt ends.
Wind the copper wire forward to create the rib.
Tie in the pearl mylar facing the back, on top of the hook shank. Wind the thread back to where the pheasant tail fibers in the abdomen ended.
Tie in several strands of peacock herl.
This recipe is compliments of Rob O'Reily.
Grab the bunch of peacock herl and wind it all forward to create the thorax. Some overlapping is usually necessary to create a bit of bulk.
Make sure you don’t crowd the eye of the hook. Pull the mylar forward tightly creating the "wing case" and tie off.

Pull the mylar back and make a few wraps of thread in front of it. Cut the excess off as close as possible.
Separate the fibers that will become the legs into two equal bunches.
Stroke the bunches back along each side of the nymph’s thorax and make several tight wraps of thread~this holds the fibers back and creates the fly’s "head".
Mix up a small batch of 5-minute epoxy and, using your bodkin, add a nice-sized drop to the top of the mylar wing case. Using the tip of the bodkin, spread it to the four corners of the wing case while trying NOT to get any on the peacock herl. Allow to dry for at least 24 hours before fishing it. Don’t "test" the 5-minute claim by touching the wing case too soon, it’ll cause the surface of the epoxy to look very dull. For obvious reasons, tie a few flies and do the epoxy bit all at once. Five minutes vest describes the working time of the epoxy before it becomes to too stiff.
