Tied by the late-great Dave Whitlock, this adult grasshopper imitation is one of the best dry fly terrestrials. This is among one of the best fly patterns Whitlock introduced. Which is saying something considering all the contributions the man made to the world of fly fishing. It imitates grasshoppers that have fallen in the water and rides at just the right depth to appear as though it’s 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. An important fly to have in your box, the magic of Mr. Whitlock is certainly within this fly.
