The Graphic Caddis is a wonder fly when caddis hatches are on. The upper body is olive green, and the lower body is a silver holographic tinsel. The silver part of the fly gives a realistic illusion of an air bubble that accompanies a pupa emerging in the water.
I cannot stress it enough; presentation is literally everything when it comes to fly fishing. If you are using quality flies that are imitating the naturals, fish will strike them repeatedly. You may have to provide a little action on your fly line to help entice them into biting. You can do this by stripping small amounts of fly line at a time, in a slow and steady manner.
