Shaner's ISO Dun

Shaner’s ISO Dun – A lifelike Isonychia mayfly imitation for selective trout.

Shaner’s ISO Dun #12 is a proven dry fly that imitates the Isonychia mayfly, a staple hatch on many trout rivers. With its slim dark body, upright wing, and delicate hackle, it creates a natural silhouette that rides low and realistic in the surface film. Designed for visibility and buoyancy, this fly is especially effective in riffles, runs, and pools during prolific ISO hatches. Durable and versatile, Shaner’s ISO Dun is a must-have pattern for anglers targeting trout keyed in on Isonychia mayflies.

Q: How do I choose the right trout fly for the conditions?
A: The best fly depends on what trout are feeding on and where you’re fishing. Use dry flies for surface feeders, nymphs for subsurface drifts, and streamers to imitate baitfish or leeches. Pay attention to water clarity, insect activity, and local hatch charts to make the right choice.
