Sparkle Dun

The Sparkle Dun, created by Craig Mathews and John Juracek in the 1980s, is a versatile dry fly pattern designed to imitate a mayfly in its emergent or newly-hatched dun stage. This fly’s defining feature is its shuck-like trailing sparkle material, which mimics the remnants of the nymphal exoskeleton. The no-hackle design allows the fly to sit low in the water, creating a realistic silhouette of a mayfly struggling to free itself from its shuck.

This fly is particularly deadly when trout are selectively sipping emergers just below the surface.
