Move beyond the round bead. Tie fast-sinking mayfly clinger and crawler nymphs with anatomically molded heads for unmatched realism.

Designed by Martin Bawden

The Evolution Mayfly Clinger & Crawler tungsten beadhead is molded after the common mayfly clinger and crawler head profile --  flat and broad with prominent eyes and a distinctive, rounded front.

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 clinger and crawler nymphs.
