The Elk Hair Caddis is a staple in your trout fly box. Imitating a hatching caddis fly, it can be tied in sizes 10-20 and in just about any color combination of dubbing, hackle, and wing. They may be thought of for trout, but you can also find uses for them to target smallmouth bass and panfish.
This is a fantastic all around baitfish pattern that can be tied in any color combo you can imagine to imitate whatever swims in your waters. The Enrico Puglisi (EP) Fibers don't absorb water, allowing for easier casting, while still pushing plenty of water. You can trim the fibers to any length or profile you want, too, making this such an easy fly to customize to your application. When tying this fly, try to keep it more sparse than you think you need - this fly will bulk up fast with too much material.
