Dry FliesIwan-E-Dun
The Iwan-E-Dun is an innovative parachute-style mayfly pattern that incorporates a unique monofilament tail system for unprecedented stability and a realistic silhouette. This elegant design features a precisely split mono outrigger tail with pale yellow mayfly tail fibers, a pale yellow dubbed thorax, a buoyant macrame yarn post, and blue dun hackle wrapped parachute-style. The result is a fly that sits perfectly in the surface film like a natural mayfly dun.

Overview
This Charlie Craven pattern from Charlie's Fly Box showcases an innovative approach to parachute mayfly imitations. The Iwan-E-Dun's most distinctive feature is its monofilament outrigger tail system, which spreads the tail fibers and provides remarkable stability on the water. This tail design creates a more realistic silhouette than traditional tail fibers while helping the fly land upright virtually every cast. The blue dun hackle over the pale yellow body perfectly matches PMD and sulphur hatches.

Fishing Tips
Season
Most effective during spring and summer mayfly hatches, particularly PMD (Pale Morning Dun) and sulphur emergences from May through August.
Presentation
Fish with a dead drift in slow to medium currents where mayfly duns float. The stable design ensures the fly lands properly oriented on nearly every cast. Focus on foam lines, seams, and edges where duns collect.
When to Use
Select this pattern during PMD and sulphur hatches or when fish are feeding selectively on pale-colored mayflies. The innovative tail design fools fish that refuse conventional patterns.
Water Type
Designed for moving water, particularly the slower pools, flat water, and tailouts where selective trout sip mayfly duns. Excels on technical waters where fish have time to inspect flies carefully.
Rigging Suggestions
Fish on a 9-12 foot leader tapering to 5X-6X tippet for delicate presentations. The light wire hook and sparse design require careful casting but reward with natural drift.
Visibility & Floatation
The macrame yarn post provides excellent visibility for the angler while the parachute hackle ensures reliable floatation. The mono outrigger tail adds stability without adding bulk.
