The Perry's Bugmeister is a great attractor dry fly. It can imitate both a large caddis, aquatic moth, and stonefly. This peacock-bodied fly floats well and is easy to see, making it fabulous for Summer trout fishing. Patterns like this are also great "searching" patterns. In other words, if there aren't many fish rising nor bugs flying around the stream, tie this fly on with a dropper to cover water and find the fish.
