The Green Warrior Caddis Nymph imitates caddis larva. These types of caddis live in fast and cold water which allows them to absorb oxygen through their skin. These larva are very strong swimmers and are not generally found in slower pools.
We fish them in the top or middle of the ripples for the best success of putting fish in the net. They have a tungsten head to help the fly sink in those quicker moving waters.
