Semperfli Dirty Bug Yarn – Caddis Brown

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 would 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. We have created a range of colors we feel stunning for both new fly tyers and skilled fly tyers alike.

Specially designed with a mix of natural and synthetic materials Dirty Bug Yarn was designed resulting from our work with different dubbings. We looked at dubbings in the market and realised many dubbings including our own different types of 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 we had some of our Pro Team work on what we called ‘Dirty Dubbing’ or blends of colors to make a better fly body whether it be a dry or nymph. From that work Dirty Buy Yarn was born. We took a range of essential dubbing colors and blends suitable for specific families of flies like caddis.

Successful this summer in both midge and Mayfly hatches (leptophlebia Vespertina) Dirty Bug Yarn can be used straight off the spool with twin strands, used as single strands for smaller flies or even broken apart as dubbing. In the Streaking Caddis (right) Tore Viggo Lillesolberg has used it twisted to create a detached body and broken apart for the hackle.
