Created by Frank Hornberg in the 1920's, this fly was originally designed to imitate a caddisfly. Interestingly enough, this pattern eventually became considered a streamer. The versatility of this fly makes it a staple in your fly box. Fish it on top when trout are feeding on adult damsels or caddisflies, or fish it as a streamer. Larger sizes will work great for bass and panfish, too!
