Fulling Mill McPhail Octopus Hackled Wet Fly is a proven Irish lough-style mayfly pattern developed by renowned fly designer Davie McPhail. Highly regarded by anglers targeting wild brown trout, this fly excels when fished across waves on both floating and intermediate lines.

The distinctive deer hair wing gives the fly natural lift and stability in the water, allowing it to sit perfectly in the surface film or just below it. Combined with the flowing hackle, this creates a highly lifelike silhouette that mimics emerging or struggling mayflies – a prime feeding trigger for trout.

When pulled steadily through a wave, the McPhail Octopus comes alive, pulsing and moving in a way that draws confident takes from even wary fish. Its versatility makes it just as effective on calm days as it is when conditions become rough.

Tied to Fulling Mill’s premium standards and supplied in Group 2 density on a size 10 hook, the McPhail Octopus Hackled Wet Fly is a must-have pattern for any angler fishing Irish loughs or targeting wild brown trout feeding on mayflies.
