While Frank Sawyer is most famous for the Sawyer style pheasant tail, he also invented one of the best cressbug/sowbug patterns ever developed. While in most cases his “killer bug” has been long forgotten about, this past winter I came across some yarn that reminded me of the original yarn that he used and began to tie a modern day “Bighorn Killer Bug.” The original yarn is no longer in production. Needless to say my modern adaptation of his original has become one of my go to sowbug patterns on the Bighorn River this year. The fly is simple to tie and looks really buggy in the water. Thanks to Ashley production tying them they are now available for sale in the shop.
