Dirty bug yarn is a lot like some dubbing tightly spun onto a thread. However, the blend of colours that it offers is stunning and, more importantly, closely matches the naturals.
If you’ve ever taken a look at the natural insects that you imitate, they rarely, if ever, have a uniform colour. Instead, the colours are mixed in, much like you see with the dirty bug yarn. An amazing material for bodies of wet flies, nymphs, and even streamers.
