This fly is tyed with trimmed hackle. During my recent trip to Syracuse, I was talking to John Shaner (Greenwell), about the use of trimmed hackle flies. He said that trimming the hackle was common in older flies.
I decided that I wanted to play around with this in some of my own fishing patterns.
In this case, I've taken an over sized Coq De Leon hen saddle hackle and stripped off one side. I then brushed the fibers backwards, so the radiated perpendicular to the center stem. I then trimmed the hackle to length and used it to tye the fly. For a starting point, I suggest trimming the hackle to roughly the distance of the hook gap you are intending to use the hackle on. Go longer (softer) or shorter (stiffer) to suit your needs.
Butt Ugly (or "Green Bugly" for short)
Hook - Mustad Model R50U/Size 12
Thread - 8/0 UNI-Thread (Olive Dun)
Hackle - Whiting Coq De Leon Hen Saddle Feather (Brown Speckled) - stripped and trimmed
Body - UNI Yarn (Olive)
The flies are not very pretty (photographically), but they have a certain "bugginess" which looks extra fishy.I recommend giving this method a try.
