Todd's Czech Nymph
As featured in The Canadian Fly Fisher (2007) and BC Outdoors Magazine (2008)Recipe:
• Hook – Snake 200 - Sizes 8 and 10
• Bead- 1/8" Tungsten (gold)
• Thread- 8/0 Fluorescent red thread
• Underbody- Thin lead or tungsten sheeting
• Shell-back- Woven Mylar shell-back material (pearl)
• Ribbing- Flattened or round copper wire
• Abdomen- Fluorescent orange, steelhead wool
• Thorax and legs- Natural Fox Squirrel dubbing Tying Instructions:
1 ) Pinch down the hook’s barb and slide the tungsten bead up to the hook eye, and secure hook in vise.
2 ) From lead or tungsten sheeting, trim a 1/16-inch wide strip 3 inches long. Attach the strip halfway through the hook bend and wrap it toward the eye with each wrap butting tight against the previous wrap but never overlapping it. Upon reaching the bead, stop and start winding a second layer back toward the bend. Stop three-quarters of the way down the first layer and start wrapping a third layer back toward the bead. Stop just short of the bead to achieve a reasonable taper to the body.
3 ) Attach thread behind the bead and wrap toward the bend to provide a solid base for the body materials. Stop where the lead wraps began.
4 ) Secure a thin strip of the Mylar shellback material to the top of the hook bend, then the gold wire. Secure with several tight wraps.
5 ) Secure a couple of fibers of fluorescent orange, steelhead wool and roll it evenly and sparsely onto the thread
6 ) Wrap the steelhead wool forward to create a tapered abdomen and stop just short of the bead
7 ) Pinch off a small portion of Natural Fox Squirrel dubbing and roll it onto the thread. Wrap forward to the bead to form the thorax
8 ) Secure thread behind the bead with a few wraps and a single half-hitch.
9 ) Pull the shellback forward to the bead and secure with two wraps and a half-hitch.
10 ) Wind the wire forward with evenly spaced wraps. Secure with several wraps of thread, whip-finish and apply a drop of head cement to the knot.
11 ) With a needle or bodkin, pick loose some of the guard hairs on the underside of the thorax to simulate legs.
This pattern is one of my personal favourites, and has been evolving on my tying bench after much experimentation in the rivers and streams that I’ve fished in North America and around the globe. This nymph is about as heavy as they come (without compromising its profile and sink-rate) and is designed to ride "upside-down”, so as to protect the hook’s point, while the stealhead wool tends to get caught in the trout's teeth - thereby allowing an extra fraction of a second for reacting to the take before the trout spits the hook.
I hope it works as well for you as it has for me...
