Semperfli Dirty Bug Yarn – Natural Buggy Dubbing on a Spool
Tying perfectly proportioned, ultra-realistic nymph and emerger bodies has never been easier. Semperfli Dirty Bug Yarn is an innovative fly-tying material engineered to mimic the subtle multi-tonal coloration and translucent texture of real aquatic insects.
Blended with multiple shades of micro-fibers pre-twisted onto a convenient spool, Dirty Bug Yarn eliminates the hassle of dubbing loops and wax. Simply tie it in, wrap it around the hook shank, and comb it out for an instantly buggy, life-like profile that traps air bubbles and drives fish wild.
