This Pattern is tied on a size 14 hook and imitates a terrestrial Hawthorne. The body is formed from black closed cell foam, tied in at the thorax and lying over the hook shank in a detached style. The big trout trigger point on this fly are the trailing pheasant tail legs, which identify this fly to the fish. The fly is completed with black cock hackle at the head. The natural Hawthorne tend to swarm near trees or bushes from late April to late May and can easily be blown on to the water surface where they are taken by trout with some relish. This fly is suitable for use on lakes and rivers.
