Mayfly Emerger | Emerger Fly | Hatching Mayfly
May fly emergers imitate the mayfly in its transitional stage between nymph and adult mayfly or dun. Emergers are some of the very most effective patterns to use during mayfly hatches. Many fish that look like they are eating adult mayflies are actually keying on mayfly emergers just below the water's surface. Mayfly Emergers can be fished by themselves or as part of a dry dropper rig.
