When midges are on the water think Griffith’s Gnat. While at first glance this fly doesn’t really appear to be a great imitation of one of the smallest insects on the water, when midges hatch heavily, they tend to cluster together in the current to create a more significant meal for hungry trout. When fished in combination with a more realistic midge or mayfly nymph as a dropper some amazing fishing can be had. It is the ultimate technical micro dry-dropper rig.
