Fly recipe

Hook: 3X Long Nymph Hook (Dai Riki #730)
Thread: 6/0 Uni Thread
Tail: Brown Goose Biots
Rib: Medium Gold Wire
Underbody: Rainy's Underbody Foam
Abdomen: Peacock Herl
Wing Case: Treated Turkey Tail
Legs: Partride Hackle
Thorax: Hare's Ear Dubbing

Tying instructions:

Slip a bead over the point of the hook and insert the hook into the vise. Attach your thread to the hook and wrap it to the rear. Tie on a couple of pieces of peacock herl at the rear of the hook and wrap them around the hook to form a small ball of herl. This will help to keep the tails split and give the tails a nice profile. Once you have the ball of herl attach the goose biots to the hook so that the tails split apart. I prefer to tie my biots on one at a time so that I can keep them in the right place. Once the tails are attached cut a piece of gold wire and attach it to the hook at the rear. This will be used to add durability as well as give the abdomen some segmentation. Next attach a piece of the underbody foam to the hook. Advance your thread forward to about half way up the hook shank and wrap the underbody foam to form a nice taper to the body. You can skip this step if you would like but I have found that the underbody foam makes a much nicer tapered body and you do not need to use as much peacock herl to cover the hook. Once you have the tapered body formed grab a clump of peacock herl ( about 15 to 20 pieces) and attach it to the hook. I tie in the herl at the middle of the hook and wrap the herl back to the rear of the hook. Once you have the herl wraped to the rear of the hook grab your gold wire ribbing and tie down the peacock herl. Continue to wrap the wire up the hook leaving even spaces between each wrap of wire. Once you reach the middle of the hook with the wire tie it off and trim the wire from the hook. You will have the remaining edges of the peacock herl sticking off the rear of the hook, all you need to do is trim the excess herl close to the wire wrap that you secured the herl with. Next cut a piece of the turkey tail feathers which you should pre treat with some kind of flexible cement. I prefer to use a product call Pliobond because it is very flexible and does it does not change the coloration of the turkey feather. I cut the peice of Turkey feather about 1/8 of an inch in width, you want it to cover the top of the hook once you have all the other materials on the fly. If you do not have turkey tails you can use a piece of brown Thin Skin or I also use Brown electrical tape which I double over and cut to size. Once you have your wing pad tied in place select two equally sized partridge feathers. These will represent the legs on the fly. Match up the two feathers by the tips and secure the tips to the top of the fly, at the same place you tied in the wing case. Once these are secure and in place make a dubbing noodle of hares ear dubbing on your thread. Wrap the dubbing around the hook to form a thorax that is slightly larger in diameter than the peacock herl that you wrapped for the abdomen. Dub the fly up to the bead or just short of the eye of the hook if you are tying a non beaded version. Once you have the thorax covered with dubbing pull your two partridge feathers over the top and tie them off at the front of the hook. Grab the turkey or other wing case material and pull it over the top and tie off as well. Trim off all the excess material at the front of the fly and whip finish the fly. Apply a drop of head cement and trim off your thread. The fly is finished.

Notes:


The Twenty incher is a stonefly nymph that was originated in the rivers of Colorado. This is a fly that I have been fishing with for almost twenty years and it has always been my go to pattern for any type of stonefly activity that occurs in the rivers of the rocky mountain region. I have had this fly in the bins at the shop for over 5 years and it has been like pulling teeth to get customers to give this fly a try. I tie them in all different sizes and in the smaller sizes this fly is a great mayfly imitation as well. This fly has it all; peacock herl, hares ear dubbing and partridge feathers, what more could you ask for on a fish catching fly. Give it a try, you will like the success that you will have.
