The Bullet Head Adult Skwalla Stonefly has the exact profile of a female skwalla stone. The deer hair bullet head, foam egg sack and foam under body make this fly float exceptionally well. The silicone rubber legs give this fly movement and a buggy silhouette. The wing color makes this fly easy to track on the water. Because stoneflies are an easy meal with excellent food value they will pull even the largest fish out of there hiding places. This pattern is also used as a grasshopper and works as a general attractor most anywhere.
