Barr's Vis-A-Dun
The perfect thorax style mayfly representation. It's low riding characteristics make it perfect for super selective trout while its white wing makes it easy for you to see. To effectively fish a dry fly you have to be able to readily see it so that you can see if a fish takes it as well as monitor your cast for accuracy and drag. All of my dry flies have white poly wings or white poly overwings. I feel that when trout are feeding on mayflies they key on the length of the body as well as the overall size and color of the fly. The color should be close to the natural but does not need to be exact. As a mayfly floats down river the fish are looking up at it from the underside of the insect and the vertically position wing is only vaguely visible to the trout if at all. A natural dun colored wing looks good to the fly fisher but I think the color of the wing is irrelevant to the fish. as is the tail. Many trout are caught on dun patterns with pink or chartreuse wings. The Vis-A-Dun is tied
