Troutline Tactical Micro Mayfly CDC Emerger is an effective imitation of small and micro mayflies, insects that can be found on many rivers from early spring until the cold days of late autumn.
Despite their small size, these delicate insects are an important food source for trout and grayling. During hatches, they can appear in large numbers, and fish often feed on them with confidence, especially in clear water and on slow or moderate currents.
This emerger imitates the most vulnerable stage of the insect, when the mayfly is trapped in the surface film and struggles to hatch. Its low-floating profile and CDC wing help the fly sit naturally in the water, creating a delicate silhouette that can trigger selective trout and grayling.
