Start the Yellow Danville 6/0 thread behind the eye and tie in the antennae: one Goose Biot on each side of the shank, curving away from each other, roughly even and not too long since the tippet will be tied in between them.
Whip finish, build a thread base where the bead will sit, add a drop of flexament or zap-a-gap, and push the Gold Bead back over it so the glue locks bead and antennae together.
Restart the thread behind the bead and dress the shank all the way back to the bend. Tie in two Goose Biots from lower on the stem (they are wider there) as the tail, one on each side, curving away from each other. Come up between them with thread to force them apart, because the lead and body will push them back together.
Tie in lead wire along the sides of the shank, then work it down with needle-nose pliers so it sits on the sides, not top or bottom. The body must be flat and broad like a stonefly with only a very slight taper.
Coat the underbody with flexament and let it go tacky, not wet, before the next step.
Pick the longest Turkey Biots. Tie one in so the wrapped biot leaves a raised ridge for segmentation, wrap it forward, and when it runs out tie in the next with a little overlap and continue. A size 8 takes about three biots; do not stretch one over the whole abdomen.
While the flexament is holding, mottle the antennae, tail and abdomen top and bottom with a permanent marker, then add more flexament over the abdomen, its weakest point.
Tie in the Turkey Tail Feather wing case at the back of the thorax, then the Brown Hen Back Feather upside down so its natural curve points away from the fly.
Spin the thorax dubbing in a dubbing loop and wrap it forward, leaving room behind the bead for the collar. Fold the Turkey Tail forward over the thorax, brush the Hen Back fibers back down either side, and whip finish.
Lay a thin base of epoxy over the wing case and come back over it once, then let it harden.
Restart the thread, dub a small collar that blends into the thorax and runs slightly back over the epoxy, whip finish, then work the collar with a dubbing brush and pick the thorax dubbing out to the sides with a bodkin.
