This pattern is tied on a size 12 hook and imitates a terrestrial Crane fly. The fly consists of a cock Pheasant tail thorax; a braid-detached body and hackle point tip wings. The legs are constructed from knotted brown monofilament. These materials make this a light pattern, subject to movement across the water surface in even a light breeze. In fact it will act very much like the natural insect, which can be blown on to the lake or river anytime from late July to the end of the season. As the Crane fly is a reasonable size meal for a trout it can often pull the bigger fish to the surface.
