Designed by Martin Bawden
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, eliminating the ugly “thread collar” so typical of many beadhead nymph patterns
Take your tying and fishing to the next level by adding the final, previously impossible, element of realism to your mayfly swimmer and burrower nymphs.
