Sparkle Dun Baetis Mayfly - 6 Flies Hook size 20

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 across species & seasons — Easily matches multiple mayfly hatches by varying size and color; a must-have confidence fly for spring, summer, and fall dry fly fishing on rivers, streams, and stillwaters

Durable, premium hand-tied construction — Built on high-quality hooks with top-grade materials for repeated use and long-lasting performance; trusted by guides and experienced anglers for over 30 years
