Jeff's Hex

Jeff’s Hex is a premium, lifelike dry fly pattern meticulously designed to imitate the adult Hexagenia limbata—one of the largest and most important mayflies in North America. Crafted with natural hues, realistic wing sets, and detailed leg construction, this pattern delivers exceptional realism both in appearance and on the water. Its segmented body mimics the size and profile of a freshly emerged Hex, while the extended silhouette and carefully placed materials help it sit perfectly in the surface film.

Built for performance during peak hatch conditions, Jeff’s Hex excels in stillwater lakes, spring creeks, and low-gradient rivers where Hexagenia hatches occur in late spring and early summer. Large trout and warmwater species target these massive mayflies aggressively, especially during dusk and into the night. This fly is a standout choice when you’re chasing trophy fish during those magic hatch hours.

Best for:

• Peak Hexagenia limbata hatches
• Stillwater lakes and slow-moving rivers
• Evening and night dry fly fishing for large trout

📌 Pro Tip: Fish Jeff’s Hex on a long leader with a drag-free drift—add occasional micro-twitches to imitate a struggling dun. This subtle motion often triggers explosive surface takes.
