Hexagenia (Hex) Dun

The Hex Adult Dun, inspired by the massive Hexagenia limbata mayfly, was originally designed by Jerry Regan, a celebrated Michigan fly tyer known for his traditional patterns that mimic local hatches. Created to replicate the fully emerged adult Hexagenia during its evening mating flights, this fly features a bulky yet aerodynamic profile to mimic the mayfly's distinct size and movement. Its ability to stay buoyant on calm and riffled waters alike makes it a favorite among anglers targeting large, nocturnal-feeding trout in the Midwest and beyond. The Hex Adult Dry shines brightest during the legendary Hex hatch, when even the wariest fish lose their inhibitions.

Skip It in the Surface Film: Instead of a traditional dead drift, try a short, skipping retrieve to mimic an adult Hex trying to take flight. This erratic motion can trigger predatory instincts in trout that ignore static presentations.
