This fly is called a spey. What is a ‘spey’ fly? The term is used to describe a type of fly featuring long body hackles. According to Monte, the modern steelhead speys look quite different than the classic spey, but they do retain a certain similarity in style. I'll have to research the classic spey to see the difference.
The origin and development of the spey fly is attributed to Scottish anglers who fished along the River Spey in Scotland during the early 1800s. A gorgeous fly!
