This is a great stonefly nymph pattern although it is a somewhat challenging and complicated fly to tie.

Tying Steps (Click on Pictures for a bigger image):

Step 1: Put the bead on the hook, at 10 - 15 wraps of lead wire. and begin the thread behind the lead.

Step 2: Tie in two boits colored to match the pattern at the bend of the hook. The boits should be about 1/3 of the shank length or less.

Step 3: Tie in a six inch length of 4x tippet for the rib. Next cut a piece of thin skin out that is about 1 1/2 times longer than the hook shank and tapered from one end to the other. Tie the thin skin in so the the shinny side (side the was in contact with the paper) is facing down.

Step 4: If you are doing a flashback pattern tie in the in tinsel on top of the flashback.

Step 5: Dub the body with the proper color to about the 60% point on the hook shank. Be sure to start out with very little dubbing and progressivly add more, to form an evenly tapered body.

Step 6: Pull the tinsel over the dubbed portion and secure it, then do the same with the thin skin. Cut the excess tinsel BUT DO NOT CUT THE EXCESS THIN SKIN. This will be needed for the thorax.

Step 7: Wrap the rib forward and tie the tippet off beyond the dubbed portion of the body the cut the excess.

Step 8: Wrap some thread back over the body to the 55% point so that the thin skin is held over the dubbed portion of the body

Step 9: Dub the first thorax in front of the dubbed body portion. The thorax should be more thickly dubbed than the body and it would extend to the 75% point on the hook.

Step 10: Take a partridge feather of the appropriate color and cut the center portion of the feather at the to forming a V. The V should be cutt so that the remaining fibers are the same length as the thorax. Tie the feather in and cut the excess.

Step 11: Pull the thin skin over the body and secure it.

Step 12: Now wrap the thread back over the thin skin as done in step 8 so that the thin skin lies above the thorax.

Step 13: Cut the thin skin at about the end of the thorax, leaving a small tag of thin skin.

Step 14: Tie in the excess thin skin for another thorax section and repeat steps 9 - 14 one or two more time so that there are two thoraxes on patterns between sizes of 18 and 10 and three on larger patterns.

Step 15: This is optional, but you can tie in a couple goose boits at the front of the hook to represent and antenea. These boits should be about the same length as the tail.

Step 16: Whip finish and head cement.
