The Henryville Special is a classic caddis fly pattern. It?s been around for a long time and the classic flies still often prevail among most. One of the best caddis imitations for sale. Its natural color both entices and fools trout over and over again. Created by Hiram Brobst and first fished in the Henryville river section of Pennsylvania. The world thanks Mr. Brobst for providing us with a caddis imitation that helps us catch more trout.
