FAQ
What makes the Evolution Mayfly Swimmer different from other mayfly patterns?
The Evolution Mayfly Swimmer features a Burrower beadhead that better mimics the movement and appearance of gilled swimming nymphs, providing a more natural action in the water.
Is this fly suitable for all types of fishing environments?
This pattern is specifically designed to imitate gilled swimming nymphs and works best in streams and rivers with moderate to fast current where nymphs are actively swimming.
Can the fly be tied with other types of beadheads?
Please contact customer service for information on alternative beadhead compatibility.



Pippa Russell –
The fly moves naturally in the water and attracts trout consistently. The tungsten beadhead adds weight without making it too heavy. I’ve used it in several streams and it’s one of my go-to nymphs.
Alison Rees –
Good imitation of swimming nymphs. The beadhead holds well and doesn’t shift during casting. Works well in clear streams where trout are active.
Ian Miller –
Highly realistic action. The gill-like movement is visible and the fly stays on the surface or just below, which is exactly what I needed for nymph fishing.
