In this week’s episode of Tying Tuesdays, watch as Brady ties The Utah Killer Bug.

The Utah Killer Bug has earned its reputation for good reason—it’s one of the best “Guide Flies” available. Incredibly simple to tie and highly effective, our version is an updated anchor fly designed to meet your heavy bug needs. It excels on a Euro rig or under an indicator when you want to avoid added weight and maintain direct contact with your flies. The Semperfli Dirty Bug Yarn is a fantastically buggy material, and the Caddis Pupa color is the closest match to the renowned Jamieson’s Shetland Spindrift Yarn in Oyster that you’ll find in the fly-tying world. If you don’t need it as an anchor fly, it still performs beautifully as a lightweight pattern by omitting the bead and lead wire. This versatile pattern works well for imitating a variety of larval or crustacean-like insects. Whether you’re fishing tailwaters, freestones, or even stillwaters, the Utah Killer Bug is an essential addition to your fly box!
