Top Mayfly Fly Patterns
Anglers travel from around the world to fish the Greater Yellowstone Region’s mayfly hatches. The region has world-renowned hatches of Drakes, Pale Morning Duns, Blue Wing Olives, and other mayfly species important to fly anglers. Mayfly hatches make for some of the area’s most technical dry fly fishing, with many different stages of insects that trout feed on. Anglers come with fly boxes full of various fly sizes, colors, and life stages of mayflies. Here are the top mayfly fly patterns I keep in my fly box for the Greater Yellowstone Region.
