A black V-rib stonefly representative based on Royal Treatment’s named Rib Roast, with biot tails, rubber legs and a bright wingcase.
The indexed “V-Rib Body Nymph – Black” has a photo label but no published dressing. Royal Treatment Fly Fishing separately publishes the black Rib Roast stonefly recipe. This page teaches that named exemplar because its black V-rib body fits the broad label; it does not identify the indexed fly as a Rib Roast or copy its image.
Work through the numbered steps in order, using the materials list and written proportions as your guide.
01
Seat bead and wire
Fit the gold slotted bead to the jig hook, add twelve close turns of .020-inch lead-free wire behind it and lock the wire beneath red thread.
Bench note Keep the weight centered behind the bead so the body taper stays smooth.
02
Set biot tails
Run the red thread toward the bend and tie a black goose biot on each side so their pointed tips form a short, spread tail.
Bench note Match the two biots before binding them down.
03
Wrap the V-rib
Bind the black nymph-size V-rib at the tail base, build a gentle thread taper and wind the rib forward in close, even turns to the front third.
Bench note Keep the convex face of the rib outward and avoid twisting it.
04
Add legs and front dubbing
Tie one pair of rubber legs on each side of the front section, then dub peacock-black Ice Dub between their tie-in points to build the thorax.
Bench note Leave the four leg groups free to flex around the dubbed front.
05
Form the opal wingcase
Pull two strands of large opal tinsel over the top of the dubbed front, bind them behind the bead, coat only the wingcase with UV resin, cure and whip finish.
Bench note Avoid flooding the rubber legs with resin.
Beyond the bench
On the water.
Use as a heavy stonefly nymph in suitable current near the bottom, particularly when large stoneflies are moving toward shore before emergence. The source discusses its use around the salmonfly hatch.
