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.

What It Is
The Czech Nymph is a specialized, weighted fly pattern designed for effective subsurface fishing, primarily in streams and rivers.

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.

Griffith’s Gnat is a versatile dry fly pattern that mimics small midges and other insects.
How to Tie It
The Griffith’s Gnat is simple yet effective, requiring only a short-shank hook, fine thread, and two key materials: peacock herl and grizzly hackle. The body consists of one or more strands of peacock herl wrapped around the hook to create a slender, segmented profile. The grizzly hackle is then palmered along the body, adding movement, imitating legs or wings, and enhancing buoyancy. This fly can be tied in various sizes to match local insect hatches.
What It Mimics
The Griffith’s Gnat imitates small midges, especially midge clusters, and other tiny aquatic insects that trout and other fish feed on. Its slender shape, subtle iridescence from the peacock herl, and lifelike movement from the hackle make it an excellent imitation of multiple insects, making it a must-have for fly anglers.
Where to Use It
This fly excels in rivers, streams, lakes, and ponds, particularly during midge hatches. For best results, present it delicately on the surface and let it drift naturally with the current. Applying floatant helps maintain buoyancy after multiple casts. Beyond dead drifting, subtle twitches can mimic a struggling insect, triggering more strikes.

What It Is
The Sand Eel Fly is a saltwater fly pattern designed to imitate sand eels and other small baitfish. It is typically fished near the bottom, where these prey species are most active.
How It’s Tied
Tied on a long-shank hook, the Sand Eel Fly features a slender, tapered body made from synthetic fibers like EP Fibers or Super Hair. These materials create a translucent, lifelike profile. The wing, crafted from bucktail, flash, or similar fibers, adds movement and flash to attract predators. For added realism, the fly often includes painted, stick-on, or epoxy eyes.
What It Mimics
This fly replicates sand eels (or sand lances), a key food source for coastal fish. Its slim shape, translucent body, and natural movement also make it effective for imitating other small baitfish.
Where It’s Used
The Sand Eel Fly excels in saltwater environments like estuaries, surf zones, and coastal areas, where sand eels and baitfish thrive. To maximize effectiveness, vary retrieves—try stripping, twitching, or swinging the fly to mimic fleeing prey.
