An Aussie fly from the late 1800's, supposedly a hopper imitation. I've seen it tied with the GP tippets parallel to the hook shank and as a pair of tips under the wing; did it as a bunch here, similar to Sawada's version. The wing came from feathers found at the butt of a pheasant tail clump; not sure what they're called but they have nice markings.
