Fulling Mill Jackie's Yellow May Dry Fly

Fulling Mill Jackie's Yellow May Dry Fly is a superb dry fly pattern created to match the brighter appearance of mayfly duns on sunny days. When the sun breaks through and clouds disappear, freshly hatched mayflies often take on a noticeably lighter, almost yellow hue – and this is exactly what this pattern is designed to imitate.

There is an old saying in the west of Ireland: “bright day, bright fly”, and this pattern proves it true time and again. On bright, clear days when trout are feeding confidently on surface insects, the Yellow May stands out perfectly against the glare and draws aggressive rises from cruising fish.

Tied on a size 10 hook and rated as Group 3, this fly is designed to float naturally in the surface film while maintaining excellent visibility. This balance of buoyancy and realism allows trout to take the fly with confidence, making it ideal for dry fly fishing during mayfly hatches.

Whether fishing large Irish loughs, stillwaters or calm river glides, Jackie's Yellow May is an essential pattern for bright weather and selective trout.
