Fly tying beads have evolved! Nymph-Head® Evolution™ is a family of tungsten fly-tying beads molded in the natural shape, size and colors of the heads of the three most common aquatic insects that trout feed upon and which fly fishermen attempt to imitate, namely mayflies, stoneflies and caddis flies. 15 Beads Per pack.
Tungsten–100% tungsten produces a fast-sinking beadhead that gets your fly into the “feeding zone” quicker!
• More Realistic Fly Profile–Evolution beadheads have been molded in the general shape and size of the heads of the three most common aquatic insects that trout feed upon: namely mayflies, stoneflies and caddisflies. This enables fly tiers to create more realistic, accurately proportionate and effective nymph imitations!
•Natural Colors–Evolution beadheads are available in natural fly colors (brown, black, olive and stonefly gold) allowing fly tiers to accurately match and blend the beadhead color to the body color of the fly. They have a permanent, high-quality anodized finish.
