Sparkle Dun Dry Fly: Created in the late 1980s by Craig Mathews of Blue Ribbon Flies in West Yellowstone, Montana, this innovative emerger pattern was designed after observing trout keying on mayflies still emerging from their nymphal shucks
Effective Mayfly Emerger Imitation: Accurately represents emerging mayflies (especially PMDs, BWOs, and other olives) with a trailing sparkle shuck that suggests the nymphal exoskeleton still attached
Premium Comparadun-Style Construction: Hand-tied with a deer hair wing, sparse dubbed body, and trailing Antron or Z-lon sparkle shuck for a natural low-riding profile in the surface film
Versatile Hatch-Matching Pattern: Performs exceptionally well on freestone rivers, tailwaters, and spring creeks during mayfly emergences; highly effective for brown, rainbow, and cutthroat trout
Essential Emerger Pattern: A modern classic that remains one of the most reliable patterns for selective trout feeding on emerging mayflies in the film
