Start the olive dun thread mid-shank and wrap a base to the bend.
Tie in two dun Microfibbetts split into a V tail about one shank length long.
For the abdomen, tie in a few olive-gray marabou barbs at the bend, twist to a rope and wrap forward to the 60% point (or wrap a single olive turkey biot forward for a segmented look).
Tie in a short mono loop at the 60% point as an upright post; lock with three wraps, then a second loop locked down for a firm post.
Tie in the medium dun hackle at the base of the post.
Dub a fatter thorax of olive-gray Superfine from the post forward to behind the eye.
Wind the hackle up the mono post 4-6 turns, fold the mono loop forward over the top of the hackle and tie off behind the eye so the fibers splay over the thorax like a parachute.
