For those who don’t know The Killer Bug is a famous fly pattern created by Frank Sawyer, a well-known fly fisherman and fly tier. Made with Chadwick’s 477 yarn, this nymph became so effective that it sparked a “gold rush” for the material. Several brands tried to replicate Chadwick’s 477 with varying degrees of success. Today, I’ve attempted to recreate it using Mojo Nymph Yarn in the A23 color. The result looks promising, and I’m excited to see how these flies perform when I fish with them. I don’t know if the Mojo A23 matches the original’s effectiveness remains to be seen, but it’s certainly an interesting experiment in fly tying.
