The Dirty White
The light gray and white shades has earned this fly its name
Hackling a tube fly with mallard is a great way of finishing it. The long mallard fibers will not only give it a great speckled veil, but also gather the rest of the fly in the water when the fibers sweep along the body and wing of the fly.
The Dirty White uses discrete and light colors combined with a natural light gray mallard front hackle to obtain a subdued but still nice appearance. The combination of yellow, white and light gray makes it a fine fly for bright conditions in clear water.
Danish fly tyer Ken Bonde Larsen has again utilized the winging technique where the wing is tied in in sections separated by flash. Since we want a fly, which is slender and torpedo-shaped there is no hackle between the sections to lift the wing, just a body hackle to add some volume to the rear of the fly.
This fly has a silver metal cone mounted, but you can omit that and tie a plain head or substitute it for a plastic cone or dish where weight is not allowed.
