The Mosley Mayfly is a versatile, substantial dry fly for the UK mayfly hatch. Its profile is designed to suggest the large adult Ephemera species that bring trout to the surface on suitable rivers and stillwaters in late spring and early summer.
Fish it only where mayflies occur, matching size and stage to the naturals. Present it dead-drift through feeding lanes and use careful line control to prevent the large dressing from skating unnaturally. A natural-looking fish catcher that deserves a place in any working dry-fly box.
