Fulling Mill Mayfly Grey Wulff – A Classic Mayfly Imitation for Irish Waters The Fulling Mill Mayfly Grey Wulff is a timeless dry fly that remains a top performer during Ireland’s famous mayfly hatches. Originally tied by American fly angler Lee Wulff in the 1930s, this pattern has earned its place in fly boxes around the world – and especially on Lough Corrib, Mask, and Sheelin. With its distinctive upright wing design and high-floating profile, it’s ideal for rougher conditions or choppy wave tops where visibility and floatation are key. Irish trout respond confidently to this silhouette, particularly when duns are riding high on the surface during late spring and early summer hatches.
