Specially designed with a mix of natural and synthetic materials Dirty Bug Yarn was designed resulting from research of different dubbings when it was realized that many traditional dubbings were often ‘single color’ dubbings. In reality if you look at a fly or nymph for example a baetis nymph it may be olive in colour but it is usually a mix of colors - nature is not monochromatic or single color. From this blends of colors to make a better fly body whether it be a dry or nymph was developed. From that work Dirty Bug Yarn was born. Essential dubbing colors and blends suitable for specific families of flies such as caddis have also been created to give tyers the very best options.

Without doubt dubbing is one of the more difficult skills for fly tyers to learn. Because of this Semperfli developed its range of ‘dubbing on a rope’ products, ready made yarns which can simply be tied and wound onto a hook. Developed twin strands Dirty Bug Yarn can be used straight off the spool for larger flies or split into single strands for smaller flies.

There are 5m / 5.4 yards (approx.) per spool of Dirty Bug Yarn
