The REC (Ralph's Emerging Caddis) is a simple but extremely effective emerger pattern to tie. It was originally tied with this dubbed abdomen color to match the emergent caddis flies on Pennsylvania's Tulpehocken Creek. However, has since proven itself on countless waters with the abdomen color tied to match any particular hatch encountered. When changing colors, I always utilize the same dubbing materials in order to maintain the intended translucency. I fish this pattern beneath an indicator most often, but it does equally as well dead-drift with a Leisenring-lift applied to the tail of the drift.
