Czech Nymph (Classic Weighted)
The original competition nymph pattern that revolutionized European fly fishing in the 1980s. Designed by Czech anglers for tight-line nymphing, this heavily weighted fly mimics caddis larvae and scuds with its curved profile, dubbed body, and scud-back shellback. The foundation pattern for all modern Euro nymphing.

How to Tie the Czech Nymph (Classic Weighted)
- 1
Step 1
Secure a curved nymph hook in the vise. Wrap a firm layer of lead or tungsten wire around the shank, covering about 2/3 of the body length. Leave space behind the eye for the thorax.
Use tungsten wire for maximum weight in the slimmest profile.
- 2
Step 2
Start thread behind the eye and secure the weight wraps, creating a tapered thread base to smooth over transitions.
- 3
Step 3
Tie in a length of fine copper wire at the bend for ribbing.
- 4
Step 4
Tie in a strip of scud back or Thin Skin at the top of the hook at the bend for the shellback.
- 5
Step 5
Dub a slim, tapered body using hare's ear or synthetic dubbing, building up from the bend toward the eye.
Keep the body reasonably slim despite the weighting—the curved hook provides the scud/caddis shape.
- 6
Step 6
Pull the shellback strip over the top of the dubbed body to create the dorsal casing. Secure with thread just behind the eye.
- 7
Step 7
Counter-wrap the copper wire rib over the shellback and body in even, spaced turns. Secure and trim.
- 8
Step 8
Add a pinch of dark dubbing or 1-2 turns of peacock herl for a contrasting thorax. Optionally add a pink/orange hotspot.
Pink or orange hotspots are frequently added for extra fish attraction in competition settings.

Step 9
Whip finish a small head. Optionally apply a thin coat of varnish or UV resin for protection.
