Parachute AuSable Hex Dun

The Parachute AuSable Hex is a high-visibility dry fly designed to imitate the giant Hexagenia mayflies that emerge during midsummer evenings. Its parachute post keeps the pattern riding low and flush, matching the natural’s broad silhouette while remaining easy to track in fading light. Originally tied for the famous Michigan Au Sable River, it has proven equally effective on other Hex-rich waters across the Midwest and beyond. Built to handle big water and aggressive strikes, this pattern delivers the buoyancy and stability needed for the legendary Hex hatch and remains a staple for anglers targeting trophy trout.

Trim the underside of the parachute hackle flat.This creates a wide, stable footprint that lets the fly ride low—matching the natural’s spent-wings posture and helping trout commit during slow, glassy Hex water.
