Byron,

You may possibly disagree but there was/is a style of fly called the 'Riffle Dun'. I won't name the tyer who, at least in one major fly tying book, is credited with its creation because that too might start some disagreeable comments. The style pattern you picture is somewhat similar. Oh, at the same time as the Riffle Dun style was developed, another pattern style known as the 'Two Feather Fly' or 'HatchMaster' was also developed but by another tyer. It was not a parachute style though. Both of these styles lend themselves to various recipies and therefore imitations of many insects. Both styles are ver effective.
Steven - Both of the fly styles I mention, when tyed properly, are just as durable as most other dry flies.
