Green Drake Dun

The Green Drake dry fly is a classic big-mayfly imitation known for matching one of the most exciting hatches of the season. Anglers popularized the pattern decades ago when they needed a large, high-floating dry that could stand up to fast water and big trout during the hatch. Over the years, tiers refined the proportions, dubbing color, and wing materials, but the pattern has always stayed true to its original purpose—matching a large, olive-green mayfly riding the surface during heavy summer emergences.

Trim the hackle flat on the bottom so the fly sits low in the film—this matches the natural better on slower slicks.
