Nymph-Head® Evolution™ Mayfly Swimmer & Burrower Tungsten Beadhead
Move beyond the round bead. Tie fast-sinking mayfly swimmer and burrower nymphs with anatomically molded heads for unmatched realism.
The Evolution Mayfly Swimmer & Burrower tungsten beadhead is molded after the common mayfly swimmer and burrower head profile – oval, elongated, and gracefully curved at the front but flattened at the back near the thorax with prominent, egg-shaped eyes.
Evolution beadheads are simpler to use and have greater versatility than ordinary beads.
The holes are slightly bigger to fit a much larger range of hook styles and sizes. This extra space is designed for lead or lead-free wire to be used with the beadhead to create better body profiles. It also allows you to create neater flies by hiding excess materials.

This beadhead is a game changer for my nymph patterns. The natural shape makes the flies look incredibly realistic. I’ve been using it with various hook sizes and it fits perfectly. The eyes are well-defined and the body profile looks authentic in the water.

I tried several beadheads before finding this one. The way it mimics a real mayfly head is unmatched. The larger hole makes tying faster and cleaner. I use it for both swimmers and burrowers and see better hook-up rates.

Great detail in the head shape. The egg-shaped eyes stand out and the curve matches real insects well. A bit harder to tie at first, but once you get the hang of it, it’s very efficient.
