When you hear the phrase \"attractor patterns\" there are a few flies that come to mind. These flies are not meant to look like anything specific, but they give off that bug-like vibe. The Humpy fits this description very well. The ample usage of Elk hair and Rooster Hackles makes this fly float extremely well. The next time you're seeing fish rise but you don't know what they're eating, give the Humpy a try.
