Notes: The Thorax Dun is a variation off the Catskill Dry by Vince Marinaro. During the
1940's , Vince examined the smooth waters of the Letort Spring Run in Pennsylvania and concluded the need to develop a fly that
would more realistically represent the sillouette of the mayfly than the Catskill Dries did. He noted that trout rises on the
Letort were dependent upon the profile of the wing and the appearance of the fly from under the water. He saw that the mayflies
were supported on the water by their legs, not it's body or tail. Vince redesigned the standard Catskill Dry so that the wing
was positioned further back towards the middle of the shank to balance the fly. Since the body should be elevated above the water
surface, Vince heavily hackled both behind and in front of the wing. Two hackle would be attached on the shank in front of the
wing. One hackle would be one size larger than standard and would be wrapped with the top hackles forward of the wing and the
bottom hackle behind the wing. The second hackle would be one size smaller than standard and would be wrapped crossing the
first. The top hackles would be behind the wing and the bottom hackles would be in front of the wing. This type of hackling
allowed the fly to keep all it's parts above the water, except the legs. Vince also found that the color of the wing needed to
match the color of the mayfly it was to represent. He insisted that the hackles should also match the color of the wings. The
color of the body was secondary to the color of the wings and hackles. Originally, split tails were designed into this pattern
to help stabilize the fly on the water surface. | ||
