The Barbless Euro Mayfly Nymph Tungsten Size 14 is a dependable, weighted river nymph for the period when large mayfly nymphs become active before the hatch. The tungsten bead gives rapid depth and the Ahrex jig hook helps the pattern fish point-up through suitable river structure.
Use it during the UK mayfly period where the natural occurs, commonly around late spring and early summer, rather than as a universal calendar pattern. Fish it on a tight-line or Euro nymph leader through deeper glides and runs, adjusting contact so it travels near the bed without dragging faster than the current.
