Developed by Harry Lemire in the mid-80's; described as a "damp waker". Tied here as an October Caddis; change colors to suit your needs. You could sub spun elk or deer hair for the collar/head if you're not into dealing with moose. Creating it with the dubbing loop isn't really that hard (waxing the thread helps, as the moose is a bit slippery); a lot easer for me than trying to spin that stuff and it makes a cool effect.
