Tying Instructions

1.Put the bead on first. Fill the void of the bead with leadfree wire.

2. Secure the leadfree wire with thread wraps and wrap a thread base to the bend of the hook above the barb which will be your tail tie-in position.

3. Attach two goose biots for tails. The length should be about 1/2 the shank length.

4. Attach the Gold Wire ribbing to the bottom of the shank and wrap to the tail tie-in position. Dub an underbody, tapered from the tail tie-in position to the 3/4 position behind the eye.

5. Wrap the thread over the underbody back to the tail tie-in position. Attach about 5-8 strands of large Peacock Herl by the tips to the rear portion of the shank.

6. Chennille the herl around the thread and wrap the herl forward creating a tapered body up to the 3/4 position of the shank.

7. Counter-wrap the ribbing forward with 5-6 wraps to help secure the herl. Secure the ribbing with thread wraps behind the bead. Attach a section of turkey tail that has been sprayed with a fixative to keep the fibers together, just behind the bead on the top of the shank with the dull side up. The width of the section should be slightly smaller than the hook gap. Wrap the Turkey Section back to the mid-point of the shank.

8. Select a partridge feather that has barbs equal to about half the shank length. Brush back the fibers of the feather so that the tip of the feather is exposed. Attach the partridge feather by the tip at the mid-point of the shank above the turkey tie-in position with the dull side of the feather up. Wrap over the remaining tip and clip any excess.

9. Dub a tight thorax from the midpoint of the shank up to the bead. Thorax should be 50% thicker than the abdomen.

10. Pull the partridge feather over the top of the hare’s mask thorax and tie it down at the back of the bead.

11. Bring the Turkey feather over the partridge feather. The partridge fibers will extend from below the turkey wingcase as legs. Trim the tag ends and secure with some thread wraps.

12. Dub a small amount of Hare’s Ear as a collar just behind the bead to cover the thread wraps and tag ends. Whip Finish.

Twenty Incher Nymph

The Twenty Incher Nymph originated in Colorado by a local tier on the Roaring Fork River. It is a pattern for stonefly nymphs but also is a good attractor nymph. It has been around for at least 20 years, probably earlier when other peacock herl body flies such as the Zug Bug and the Prince Nymph became popular.

Excellent Skwala nymph pattern

It remains an excellent stonefly pattern within the Sierra, particularly the Skwala hatch in sizes 8 and 10. Smaller sizes can be tied to imitate mayfly nymphs. When tying the larger sizes, try using a dubbed underbody with a tapered shape. This will help to get the proper size and shape when using the herl overbody. A TMC 200R gives a nice curved look to the fly. Beadheads are very popular with this pattern in assisting the fly to get to the bottom. 

Biots

I am also using Turkey Biots for the tail, you could use Goose biots which are stiffer and more durable. The Turkey biots give this pattern nice movement. The original wingcase was a Turkey Quill segment, however, many today use Pheasant Tail fibers. Some will apply a thick fly finish to the casing for added durability. The ribbing can be Gold or Silver Wire. Some will use oval tinsel or flashabou.

Presentation

Fish this pattern within the rocky bottoms of runs and riffles but where the current is not too strong so that the trout can examine the fly. It is realistic enough to fool a selective trout. In streams or rivers, this pattern can be presented in a number of ways the most successful being a cast up stream like a dry fly and then allowing it to dead drift drag free, keep in contact with your line.

Alternatively, allow the nymph to sink slowly to the bottom just above the vegetation it often seeks and slowly raise the line on the drift, through the water table to attract attention. A slight variation on this is to actually tighten up the line or pull the line as your nymph approaches the lie of a fish you are sight fishing, this will imitate the natural movement of the nymph through the water table.
