What It Is
The Czech Nymph is a specialized, weighted fly pattern designed for effective subsurface fishing, primarily in streams and rivers.
How It’s Tied
Tied on a curved or jig hook (sizes 8–16), the Czech Nymph is heavily weighted with lead wire or a tungsten bead for quick sinking. The body uses materials like dubbing, synthetic fibers, or floss, often segmented with 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 fly imitates caddisfly and mayfly nymphs in their larval stage. Its weight and shape help it hug the riverbed, accurately representing bottom-dwelling insects. Available in various sizes and colors, it adapts to local nymph populations.
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.

How It’s Tied
The Elk Hair Caddis is tied on a short-shank hook with a dubbed fur or synthetic body. Its signature wing, made from a tuft of elk hair, ensures buoyancy and a lifelike silhouette. The hair is flared and secured at the head before being trimmed to shape. A palmered hackle often runs along the body, imitating legs and enhancing floatation. This versatile fly comes in various sizes and colors to match local caddisfly species.
What It Mimics
This pattern replicates adult caddisflies, a crucial food source for trout and other fish. Found in diverse waters, caddisflies make the Elk Hair Caddis a must-have fly. Its realistic profile, buoyancy, and natural movement on the surface entice fish to strike.
Where to Use It
Effective in rivers, streams, and lakes, the Elk Hair Caddis shines where caddisflies thrive—especially during hatches when fish feed aggressively on the surface. For best results, cast gently and let the fly drift naturally, imitating a resting or struggling insect.

How It’s Tied
The Biscuit Fly is tied on a short or medium shank hook. It uses either spun deer hair (as shown in the picture) or closed-cell foam, shaped into a rounded or oblong form to mimic a piece of biscuit. Simple yet highly effective.
What It Mimics

Unlike traditional flies that imitate insects or aquatic organisms, the Biscuit Fly replicates a piece of biscuit. It works best in warm months when carp feed actively, especially in areas where they are accustomed to human food—like city parks where they eat bread, cookies, or popcorn.
Where It’s Used
This fly excels in carp-rich waters such as lakes, ponds, slow rivers, and canals. During warm weather, carp often cruise near the surface, making the Biscuit Fly an ideal choice. Pro tip: Resist the urge to twitch it. When a carp approaches, let it sit still—wait until they suck it in for the best results.
