How to tie it
Seat the gold tungsten bead at the eye, then wrap 10-12 turns of.020 lead behind it and shove them into the back of the bead to lock it. This is a scaled-up Copper John built as a golden stone.
Start thread and tie in two brown goose biots at the bend, splayed into a short V-tail.
Tie in one amber and one black wire strand at the bend. Wrap them forward together as a two-tone segmented abdomen to the 60% mark; tie off and helicopter the wire to break it.
Over the top, tie in a strip of Thin Skin and a strand of peacock/orange Mylar for the flashback, both pointing rearward for now.
Dub a thick brown-stone thorax noodle forward over the front third, stopping short of the bead.
Figure-8 a pair of barred rubber legs on each side of the thorax so they splay out; trim to a shank length.
Pull the Mylar flashback forward over the thorax, then the Thin Skin wing case over that, and tie both down behind the bead.
Wrap a speckled hen saddle as a soft collar between thorax and bead, 1-2 turns, and sweep the fibers back.
Whip finish behind the bead and add a drop of head cement; a coat of UV resin over the wing case adds durability.
