This adult grasshopper imitation is one of the best dry fly terrestrials. This is among one of the best fly patterns whitlock introduced. It imitates grasshoppers that have fallen in the water and rides at just the right depth to appear as though it is partially submerged. Cast these flies upstream and let them drift down naturally. They are best suited for slow waters whereas foam hoppers will perform better in faster and rougher waters. This is certainly an important fly to have in your box. This 10-Pack includes flies tied in the most effective hook sizes (#10, 12, 14) for this pattern, providing top performance on the water.
