Sparkle Dun BWO

The Sparkle Dun BWO is one of the most effective Blue-Winged Olive imitations ever tied. Craig Mathews' iconic pattern combines a trailing Z-lon shuck with a comparadun-style deer hair wing that flares perfectly in the surface film, creating an irresistible silhouette for rising trout during Baetis hatches.

A staple pattern for spring and fall fishing on Colorado's technical rivers. Fish it during the classic afternoon BWO hatches on the Fryingpan, Roaring Fork, and Colorado River when trout are sipping emergers in the film.
