Sparkle Dun Pale Morning Dun Yellow Body PMD Mayfly
Proven mayfly emerger & dun imitation — The legendary Sparkle Dun pattern, originally developed by Craig Mathews, perfectly mimics emerging and stillborn mayflies (PMDs, BWOs, Sulphurs, Baetis, and more) during hatches, fooling even selective trout on technical waters like Henry’s Fork and tailwaters.
Trailing shuck design for realism — Features a sparkling Z-lon or Antron shuck that imitates the nymphal casing left behind during emergence, making it deadly effective when trout key on cripples or emergers rather than perfect duns
Low-riding, high-floating profile — Sparse deer hair wing and dubbing body ride flush in the surface film for a natural drift in slow glides, riffles, and spring creeks; highly visible to anglers yet subtle to wary fish
Versatile and effective for a wide range of mayfly hatches in both stillwater and moving water conditions.

FAQ
What types of mayflies does the Sparkle Dun pattern imitate?
The Sparkle Dun pattern mimics emerging and stillborn mayflies such as PMDs, BWOs, Sulphurs, and Baetis.
Why is the trailing shuck important in this pattern?
The sparkling shuck imitates the nymphal casing left behind during emergence, making it effective when trout target cripples or emergers.
How does the pattern perform in different water conditions?
It performs well in slow glides, riffles, and spring creeks due to its low-riding, high-floating profile that stays natural in surface film.

Anne Knox –
Used this pattern during a spring hatch on a cold stream. The shuck detail made a big difference when targeting wary trout. It drifted naturally and caught several fish on a slow drift.
Amy Henderson –
Felt very realistic in the water. The yellow body and shuck matched the actual mayfly emergence. Worked well in both riffles and open water sections.
Bella Tucker –
Caught three trout in a row on a technical section of a tailwater. The pattern stayed on the surface without sinking, and the shuck detail fooled even selective fish.
Piers Short –
Good for both emergers and stillborn mayflies. The floating action is smooth and the color is accurate to real hatches.
