Dry FliesImproved Baetis Sparkle Dun
The Improved Baetis Sparkle Dun is an enhanced version of the classic Sparkle Dun designed specifically for Blue-Winged Olive mayflies. The sparkle dun deer hair wing creates an impressionistic wing profile, while the trailing Zelon shuck and grey olive dubbing body complete the emerger silhouette. This pattern excels during selective Baetis feeding.

Overview
The Improved Baetis Sparkle Dun was developed at Blue Ribbon Flies as a refinement of Craig Mathews' original Sparkle Dun pattern. The improvements include refined proportions and color matching specifically for Baetis mayflies. The sparkle dun deer hair creates an impressionistic wing that fish find convincing without the bulk of traditional wings.

Fishing Tips
Season
Most effective during spring (March-May) and fall (September-November) Baetis hatches. These are the peak times for BWO activity on most waters.
Presentation
Dead drift in feeding lanes with precise drag-free presentations. The pattern should ride with the body in the film and wing upright. Focus on slow water and seams where emergers collect.
When to Use
Best during Baetis emergences when fish are taking emergers in the film. Try when fish refuse fully emerged dun patterns but continue to rise steadily.
Water Type
Ideal for spring creeks, tailwaters, and technical freestone water. Most effective in flat water and slow runs where fish can inspect flies closely.
Rigging Suggestions
Fish on 12-15 foot leader with 6X-7X tippet. The small hook sizes demand fine tippet and accurate casting. Fluorocarbon helps with visibility in clear water.
Visibility & Floatation
The deer hair wing provides good floatation and visibility. Pattern rides low in the film like a natural emerger. May need periodic drying on smaller sizes.
