Dry FliesSLS Improved Sparkle Dun
The SLS Improved Sparkle Dun is a refined version of the classic Sparkle Dun pattern using SLS (Short-Legged Sulphur) Zelon dubbing to match the pale yellowish-tan coloration of many summer mayflies. The barbless hook and Epeorus-colored shuck make this pattern ideal for matching Pink Ladies and similar species during summer emergences.

Overview
The SLS Improved Sparkle Dun was developed at Blue Ribbon Flies as a refinement of the original Sparkle Dun for matching specific mayfly species. The SLS coloration refers to the pale, sulphur-yellow tones common to many summer mayflies. The barbless Tiemco 206BL hook allows easy release and reduces fish handling time.

Fishing Tips
Season
Most effective from June through August during summer mayfly hatches. Particularly productive during Epeorus (Pink Lady), Sulphur, and similar pale mayfly emergences.
Presentation
Dead drift in the surface film with minimal drag. Focus on the heads of pools and riffles where female mayflies return to lay eggs and where emergers concentrate.
When to Use
Best during summer mayfly emergences when fish are being selective. Try when fish refuse standard mayfly patterns but continue to rise steadily to emergers.
Water Type
Ideal for spring creeks, tailwaters, and technical freestone water. Most effective in flat water and slower runs where fish can closely inspect flies.
Rigging Suggestions
Fish on 10-12 foot leader with 5X-6X tippet. The barbless hook makes for easy releases but requires careful fish playing. Keep the wing dressed with floatant.
Visibility & Floatation
The natural sparkle dun deer hair provides good visibility and floatation. Pattern rides in the film with the shuck trailing below. May need periodic drying.
