Mount the hook and build a tapered thread abdomen with light Cahill thread, packing the rear end noticeably fatter than the front.
Switch to brown thread, fill out the rest of the tapered abdomen, and coat the whole thread body with a heavy layer of hard head cement for durability.
Stack a healthy clump of natural elk hair and bind it on top as an underwing extending past the bend.
Knot two turkey-tail fibers for the trailing legs, bind one to each side, trim to length and touch with cement.
Cut two tapered wing slips from mottled wing material and bind them flat over the elk hair.
Tie in a badger hackle at the front and dub a black Hare-Tron thorax.
Wind the hackle forward through the thorax in 4-5 turns, tie off, whip finish and cement.
