Dry FliesPMD Sparkle Dun
The PMD Sparkle Dun is Craig Mathews' classic emerger pattern tied specifically for Pale Morning Dun mayflies. The sparkle dun deer hair wing creates an impressionistic silhouette while the trailing Zelon shuck and pale yellow dubbing body complete the emerger profile. This pattern excels when PMDs are emerging and fish become selective.

Overview
The PMD Sparkle Dun follows Craig Mathews' original Sparkle Dun design, refined specifically for Pale Morning Dun hatches. The pattern was developed in West Yellowstone for the technical spring creek and tailwater fishing in the region. The natural sparkle dun deer hair creates a translucent wing effect that fish find convincing during heavy emergences.

Fishing Tips
Season
Most effective from late May through August during PMD hatches. Peak performance during afternoon hours when PMD emergence is strongest on most waters.
Presentation
Dead drift in the surface film with the body riding in the film and wing upright. Focus on feeding lanes and seams where emergers collect. Accuracy and drag-free drift are essential.
When to Use
Best during PMD emergences when fish are taking emergers rather than fully emerged duns. Try when fish refuse standard mayfly patterns but continue rising consistently.
Water Type
Ideal for spring creeks, tailwaters, and technical freestone water. Particularly effective on western rivers like the Henry's Fork, Madison, and Yellowstone where PMD hatches are legendary.
Rigging Suggestions
Fish on 10-12 foot leader with 5X-6X tippet. The pattern floats well but may need periodic drying. Keep the wing dressed with floatant.
Visibility & Floatation
The natural deer hair wing provides good visibility and floatation. Pattern rides in the film like a natural emerger. May need occasional drying during extended use.
