The Alder Fly Barbless imitates the dark adult alder fly found around the margins of rivers and stillwaters. Alders hatch from aquatic larvae, but adults are often encountered on bankside vegetation and may be blown or fall onto the water.
Fish it near overhanging trees, reeds and shaded margins when the naturals are present. Allow it to sit naturally in the film, using a small twitch only to suggest a struggling adult. Its balanced profile gives it the appeal to turn interest into a solid take.
