How It’s Tied
The Czech Nymph is tied on a curved or jig hook (sizes 8–16). Heavily weighted with lead wire or a tungsten bead, it sinks quickly to the bottom. The body, made of dubbing, synthetic fibers, or floss, is segmented with fine wire or contrasting thread. A built-up thorax—using extra dubbing or shellback material—creates a pronounced profile, mimicking the swollen thorax of aquatic insects.
What It Mimics
This pattern imitates caddisfly and mayfly nymphs in their larval stage. Its weight and shape keep it near the riverbed, replicating bottom-dwelling insects. Available in various sizes and colors, it adapts to local hatch conditions.
Where It’s Used
Ideal for fast-moving rivers and streams, the Czech Nymph excels in targeting trout and grayling that feed on dislodged nymphs. It’s fished using Czech or European nymphing techniques—short, controlled drifts with a tight line to detect subtle strikes.
