Features of the Purple Haze
Andy Carlson, a fly fishing guide on the Bitterroot River in Montana originated the Purple Haze fly pattern.
It closely resembles a Parachute Adams with a purple body.
This has been a very effective pattern in Montana and has become a popular dry fly in general.
It is used to match Blue Wing Olives, Mahogany Duns, Green Drakes, and Tricos.
