How It’s Tied
The Ant Fly replicates the appearance and buoyancy of a real ant using simple yet effective materials. A short-shank hook creates a compact profile, while the body is crafted from foam, fur, or dubbed synthetic fibers. Thread wraps or contrasting materials add segmentation, and rubber or synthetic fibers can be used for legs. This straightforward design allows for customization in size, color, and materials to match local insect hatches.

What It Mimics
This fly imitates ants and other small terrestrial insects that often fall onto the water’s surface. As a key food source for surface-feeding fish, the Ant Fly excels at triggering strikes, especially in summer or after rain when terrestrial activity is high. Its realistic yet simple design makes it a must-have for any fly angler.
Where It’s Used
Versatile and effective, the Ant Fly works well in rivers, streams, lakes, and ponds—particularly near overhanging vegetation, grassy banks, or areas with abundant terrestrial insects.
How to Fish It
Present the fly delicately on the surface, letting it drift naturally or adding subtle twitches to mimic a struggling insect. It can be fished alone as a dry fly or paired with a dropper nymph. Watch for gentle takes, as fish may sip it quietly, requiring a quick and precise hook set.

Versatile Streamer Pattern
The Humungus fly features a marabou tail and a flashy body, creating lifelike movement to attract fish.
How to Tie It
Tie the Humungus on a short or medium shank hook. Use marabou feathers for the tail, ensuring natural movement in the water. Construct the body with chenille, tinsel, or other flashy materials wrapped around the hook. Some variations include a bead, cone, or dumbbell eyes for added weight, helping the fly sink to the desired depth. Others use large foam eyes to mimic a small baitfish on the surface. The pattern shares similarities with the Woolly Bugger.
What It Mimics
The Humungus imitates small baitfish, leeches, and large nymphs—key prey for predatory fish. Its realistic profile, marabou tail, and flashy materials make it highly effective for enticing strikes.
Where to Use It
This fly excels in both freshwater and saltwater. It targets a wide range of predatory species, from trout to sea bass.

Profile
The Mickey Finn features a sleek, shiny body with vibrant yellow and red/orange wings, perfectly mimicking small baitfish. This versatile fly effectively targets both freshwater and saltwater species.
How It’s Tied
The Mickey Finn is tied on a long-shank hook using simple materials. The body is crafted from flat tinsel or floss, wrapped tightly to create a slim, reflective profile. The wing—its standout feature—is made from stacked bucktail in yellow and red, layered meticulously and secured at the head before being trimmed to shape. Some variations may include hackle fibers for a throat or an epoxy head for added durability.
What It Mimics
Designed to imitate small baitfish like minnows, shiners, or dace, the Mickey Finn’s slender form, bright colors, and lifelike movement make it irresistible to predatory fish.
Where It’s Used
Adaptable to all water types, the Mickey Finn excels where baitfish are abundant or fish are aggressively feeding. To maximize effectiveness, vary your retrieve—strip, twitch, or swing the fly to mimic the erratic motion of injured prey.

Target Species
While primarily used for trout and bass, the Mickey Finn also proves deadly for pike, musky, and saltwater species like seabass, sea trout, and redfish.

What It Is

The Diawl Bach is a subtle, small nymph pattern effective for targeting various freshwater species.
How It’s Tied
The Diawl Bach is tied on a short or medium shank hook with a slim profile. The body, typically made of dubbed fur or synthetic fibers, is wrapped to create a slender, tapered shape. Fine wire or tinsel ribbing adds segmentation. The tail and legs consist of hackle or pheasant tail fibers. Some variations include a bead or thorax cover for added weight or attraction. Despite its simplicity, this pattern is highly effective.
What It Mimics
This fly imitates small nymphs and other aquatic insects, making it ideal for clear water conditions.
Where It’s Used
The Diawl Bach excels in all freshwater environments. Fished as a nymph, it can be used with an indicator or tight-line (Euronymph) techniques.
