Semperfli Dirty Bug Yarn Dubbing Spool

Product Code

Specially designed with a mix of natural and synthetic materials Dirty Bug Yarn was designed resulting from Semperfli's work with different dubbings. Dirty Dubbing has a blend of colours to make a better fly body whether it be a dry or nymph.

Colours Available: Danica, Caddis Brown, Ivory, Mottled Caddis, Mottled Olive and Shrimp

Size: 5m spool

  • Semperfli have developed the 'dubbing on a rope products', ready made yarns which can simply be tied and wound onto a hook. Multiple colours have been blended creating a 2-ply yarn
  • Diry Bug Yarn can be used straight off the spool for larger flies or split the 2-ply yarn into single strands for smaller flies.
  • You can twist the Dirty Bug Yarn to form detached bodies.
  • It can also be broken down to use as dubbing.
  • Has the multiple colours found on insects and invertebrates so suitable whether you are tying shrimps, baetis nymphs or caddis nymphs.
