Brown Stone Nymph

One of my favorite go-to nymph patterns is a Brown Stonefly Nymph. I usually turn to it when there is no hatch and I can’t find success with a Gold Ribbed Hare’s Ear or the tried-and-true PT Nymph. This Brown Stonefly Nymph and others like it are killer patterns in large streams with rapid current creases and rolling water. Drop it anywhere you think a trout might lurk, as near to bottom as you can, and you’re liable to hook a nice trout. By nice, I mean something above 14 inches. Brown trout, especially, seem to relish this mouthful of protein, but rainbows and cutthroats take it, too.


Hook: Mustad 79580 or equivalent, size 6 to 10

Thread: Danville yellow Monocord

Ribbing: Danville yellow single-strand flat waxed nylon

Tails: Dyed tan wild turkey biots, hook gap length

Abdomen: Mixture of yellow and brown dubbing. Aim for a golden brown color

Shellback: Segment of wild turkey secondary feather

Legs: Mottled tan hen back feather

Thorax: Same as abdomen but a bit larger in diameter

  1. Debarb the hook, put it in the vise and attach some lead substitute wire about a hook gap behind the eye. Wind to just above the hook point. Cover the wire with two layers of tying thread and a dab of head lacquer. Create a small ball of dubbing at the end of the shank and tie in a pair of dyed biots. Attach the turkey segment by its tip, with the shiny side up. Tie in the ribbing on your side of the hook.
  2. Create a dubbing loop, insert dubbing and wind to a hook gap-and-a-half behind the eye. Fold shellback forward, tie down and reverse-wrap the ribbing to the tie-down of the shellback.
  3. Fold the shellback to the rear, take a turn or two of thread to hold it back, and tie in the tip of the hen back feather, with butt to the rear and the shiny side up. Create another dubbing loop, and insert more dubbing than you used for the abdomen. Wind forward to create a fatter thorax. Tie down and clip off excess. Fold hen back feather forward, tie down and clip off excess.
  4. Fold shellback forward to create the wing case and tie it down behind the eye, clip off excess. Apply a liberal amount of head lacquer to the wing case area and thread head only.
  5. Finished fly.
