When we look closely at insects and invertebrates they are not just one color but a range of mixed colors across their body. So why do we often use single color dubbing to imitate nature? That was the big question the Semperfli Pro Team was asking. As a result we developed Dirty Bug Yarn. We call it Dirty Bug Yarn because it has the multiple colors found on insects and invertebrates, whether you are tying shrimp, baetis nymphs, caddis nymphs it does not matter. We decided to blend multiple color materials into Dirty Bug Yarn creating a 2 ply yarn so that you can tie larger nymphs or split the 2 ply yarn for smaller flies.

Perfect for making different colors of the Utah Killer Bug!
