Brass bead Blood red/brown (or copper) (1, to suit hook)

Tying wire, large March brown (copper or gold fine) (1 length for rib)
Dirty Bug Yarn Mottled dark green dirty bug yarn (1 strand for the back)
Dirty Bug Yarn Orange aphid + mottled golden olive (1 long strand of each for body)
Ice Dub Brown dubbing (Thin noodle for thorax)
Brahma hen feather March brown (partridge or grouse fine) (1 with long fibers)
How to tie it
Slide the bead on and wind about 12 wraps of lead-free wire onto the shank. Start the thread a little behind the bead, lock the wire down front and back, then run the thread about halfway down the bend.
Tie in the large march brown wire rib behind the lead and bind it to the rear.
Tie the mottled dark green yarn strand in so it lies along the top of the shank all the way down, this becomes the back.
Take one long strand each of orange aphid and mottled golden olive yarn and tie them in together at the same point. Bring the thread forward to where the thorax will start.
Wrap the orange/olive pair two or three turns at the rear to form the first segment, pull the green strand forward over the top, and lock it with one tight turn of the orange pair.
Pull the green back again and repeat (wrap a segment, pull the green over, lock it) building three or four segments with a rising taper. Tie off the orange pair, then bring the final stretch of green over the top and tie it off, leaving at least a bead and a half of bare space at the front.
Half-hitch, then brush the body very lightly with velcro. Rib the wire forward: one full turn at the back, then even turns up the body, pulling tight from underneath so the back doesn't shift. Tie off and twist the wire free.
Half-hitch again and brush the body out a little more so the yarn traps air and looks alive; trim any wildly long fibers.
Wax the thread and dub a thin noodle of brown Ice Dub into a compact thorax, keeping room for the hackle.
Tie in the Brahma hen by the stem (shiny side toward you, bit of bare stem left to orient it), sweep the fibers back and wind a full collar whose tips stop just short of the rear of the fly. Tie off, build a small brown collar head, whip finish and glue; brush the thorax out a touch if you want it buggier.
