Introduction
The Copper John is a fast-sinking nymph pattern renowned for its versatility and effectiveness in imitating subsurface insects. With its weighted copper body, lifelike profile, and rapid descent, it’s a must-have fly for anglers targeting trout and other fish species that feed on nymphs.
How to Tie the Copper John
- Hook & Weighting: Start with a short or medium shank hook and add a tungsten or brass bead head for extra weight.
- Body Construction: Wrap copper wire tightly around the hook shank to form a dense, cylindrical body. Add wire ribbing for segmentation and durability.
- Thorax & Wing Case: Use peacock herl for the thorax to create a contrasting texture. For the wing case, secure a thin material like Flashabou or Thin Skin over the thorax and fix it behind the bead head.
This streamlined construction ensures the fly sinks quickly while maintaining a realistic appearance.

What the Copper John Imitates
The Copper John mimics a wide range of aquatic insects, including:
- Mayfly nymphs
- Stonefly nymphs
- Caddisfly larvae
Its generalist design makes it irresistible to fish, as it suggests multiple food sources in one pattern. The weighted body and natural movement enhance its effectiveness in turbulent or deep waters.
Best Places & Techniques to Fish the Copper John
- Water Types: Effective in rivers, streams, lakes, and ponds, especially in deep or fast-moving water.
- Fishing Methods:
- Dead Drifting: Let the fly sink and drift naturally with the current.
- Swinging: Allow the fly to swing across the current to trigger strikes.
- Nymphing with an Indicator: Use a strike indicator to detect subtle takes.
- Adjustments: Vary depth and retrieve speed to match fish feeding behavior.
Why the Copper John is a Must-Have Fly
- Fast Sinking: Reaches feeding zones quickly.
- Versatile Imitation: Works as a mayfly, stonefly, or caddisfly mimic.
- Year-Round Effectiveness: Produces results in all seasons.
Whether you’re a beginner or an expert, the Copper John is a reliable fly that consistently delivers results. Add it to your fly box and experience its unmatched effectiveness on your next fishing trip!
The Griffith’s Gnat is a must-have dry fly for anglers targeting trout and other fish that feed on small insects. Its simplicity, versatility, and effectiveness make it a staple in any fly box. Below, we break down everything you need to know about this legendary pattern—from how it’s tied to where and when it works best.
What Does the Griffith’s Gnat Imitate?

This fly excels at mimicking small midges, especially midge clusters, as well as other tiny aquatic insects. The peacock herl body provides a subtle iridescence that mimics natural insect coloration, while the grizzly hackle adds lifelike movement, imitating legs or wings. Its slender profile makes it a convincing imitation, fooling even the most selective fish.
How to Tie the Griffith’s Gnat
One of the biggest advantages of this pattern is its simplicity. Here’s what you’ll need:
- Hook: Short shank (sizes 16–22 are most effective)
- Thread: Fine, matching the body color
- Body: 1–2 strands of peacock herl (wrapped to create a segmented look)
- Hackle: Grizzly hackle, palmered along the body for buoyancy and movement
Tying steps:
- Secure the thread and wrap the peacock herl to form the body.
- Palmer the grizzly hackle forward, ensuring even spacing.
- Tie off and whip finish.
The fly can be adjusted in size to match local insect hatches.
Where & How to Fish the Griffith’s Gnat
This fly shines in rivers, streams, lakes, and ponds, especially during midge hatches—common in cooler months or early mornings.
Fishing Tips:
- Presentation: Cast delicately to avoid spooking fish. Let it drift naturally on the surface.
- Floatant: Apply sparingly to keep it riding high after multiple casts.
- Movement: Occasionally twitch the fly to mimic a struggling insect, triggering strikes.
Why Every Angler Should Carry This Fly
- Versatile: Works in various water types and conditions.
- Effective: Consistently produces strikes during midge activity.
- Easy to Tie: Perfect for beginners and experts alike.
Whether you’re facing a tough hatch or need a reliable dry fly, the Griffith’s Gnat is a proven winner. Add it to your arsenal and watch your success rate soar!
The Squirminator is a modern, highly effective nymph pattern designed to imitate aquatic worms—a staple food source for trout and other freshwater species. Its lifelike movement, simple construction, and versatility make it a must-have in any fly angler’s arsenal.
What It Mimics
The Squirminator replicates aquatic worms, such as annelids and midge larvae, which are a critical part of many fish diets. These worms are often dislodged by currents or high water, making them an easy and irresistible target for feeding fish.
How It’s Tied
This pattern is simple yet effective:
- Body: Made from stretchy "Squirmy Wormy" material, wrapped around the hook to create a worm-like profile.
- Ribbing: Wire or thread secures the material and adds segmentation for realism.

- Thorax: Built with dubbing (natural or synthetic) to add bulk and texture contrast.
- Head: Finished with a tungsten or brass bead for weight and added attraction.
Where & How to Use It
The Squirminator excels in:
- High or discolored water, where fish rely on dislodged prey.
- Nymphing setups, either dead-drifted under an indicator or tight-lined for deeper presentations.
Similar to the San Juan Worm but with enhanced movement and durability, the Squirminator is a go-to pattern for fooling even the most selective fish. Whether you’re fishing murky flows or pressured waters, this fly delivers consistent results.
Pro Tip: Experiment with colors—natural tones like red, pink, or brown often work best, but bright variations can trigger strikes in stained water.
Tie it, fish it, and watch your catch rates soar!
The Mayfly is one of the most essential insects in fly fishing, serving as a primary food source for trout and other freshwater species. With over 3,000 species across 42 families, matching the hatch requires skill and knowledge. This guide covers everything from tying techniques to strategic fishing applications.
Understanding the Mayfly Lifecycle
The Mayfly Pattern imitates various stages of the mayfly’s life, from nymph to adult. The most recognizable form is the dry fly, representing the winged adult stage. However, successful anglers must also match emerging nymphs and cripples, depending on the hatch conditions.
How to Tie the Perfect Mayfly Pattern
Mayfly imitations vary widely in size (hooks #22 to #8) and materials, depending on the target species and stage. Key components include:
- Body: Dubbing, synthetic fibers, or natural materials like pheasant tail.

- Wings & Legs: Hackle feathers, deer hair, or synthetic alternatives.
- Tail Fibers: Microfibbets, hackle fibers, or pheasant tail fibers.
Experimentation is crucial—adjust colors and proportions to match local mayfly species.
Where and When to Fish the Mayfly Pattern
This pattern excels in rivers, streams, and lakes, particularly during hatches. Prime locations include:
- English chalk streams, renowned for spectacular mayfly hatches.
- Spring creeks and tailwaters, where mayflies thrive year-round.
Before fishing, research local species and their active stages. Observing water conditions and insect activity will significantly improve success rates.
Why the Mayfly Dominates Fly Fishing
As a cornerstone of freshwater ecosystems, the mayfly’s abundance makes it irresistible to fish. By mastering pattern variations and presentation techniques, anglers can consistently fool even the most selective trout.
