The Gray Hackle is one of the most solid midge patterns out there. Its unconventional hackle pattern is unique to the world of midge imitations. It’s a trout fly that isn’t special in one way, except for the fact that it works. Skidded across the water’s surface or fished with a dead drift are both great options for this trout fly. Having midges in your box is always smart and this pattern is a solid choice for the imitation of small insects.
