Monkey Faced Louise is the original name for a popular fly now widely known as the Carey Special
The fly pattern was developed in the early 1920s by Dr. Lloyd A. Day and Colonel (Tom) Carey in British Columbia, Canada. The original name, "Monkey Faced Louise", has an unknown origin, although one rumor suggests it was named for the creator's girlfriend. The fly was later renamed the Carey Special in honor of Colonel Carey, who popularized its use among local anglers.
I ran across this fly a few years ago and saved it in my list of flies to tie someday. And then, like most of the flies on that list, I totally forgot about it. Recently while trying to decide on a list of flies for an upcoming adventure I ran across it again. This time I put it on the list of flies to take on this trip. It's a long ways off but I've been having a fun time playing with this one and it will see some Missouri action soon.
The patterns listed for both patterns varies wildly. This is what I came up with.
