I wish I had underwater video of the flies action for it was remarkable. As the fly lay motionless in the current the darker portion of the fly expanded which chickabou will do. Well that expansion drew some violent strikes and that led me to believe the brookies were taking it for a sculpin. Many small streams have generous populations of sculpin and they are a sought after food source for trout.
A brookie that took the chickabou fly.
In this riffled section of stream is where the chickabou fly was taken as a caddis.
When wet you can see a sculpin like resemblance. From a large head to a thin tail. And when the water flows through it life is put into action. I have tied a variant of it using a short shank hook. More on that later.
