Reminiscent of the classic Carey Special but with a little more definition. This pattern can be a killer just about any time but really shines when trout are keying on emergers. Depending on the fly line and retrieve used, this pattern will imitate emerging caddis and dragonfly nymphs as well as many other aquatic insects. Per 3. Sizes: 8, 10. Colors: (009)Olive, (048)Grey.
