The key to effectively fishing either of the caddis larvae is to ensure you get the fly on the bottom. Fishing a caddis larva seems to be more effective in moving water than in lakes and a dead drift presentation right along the bottom works best. They have long abdomens with their wings, legs, and antennae flowing down and back towards their rear. They also have very long swimmeret legs with hairy ends that the pupae use like oars to quickly swim to the surface after they emerge from their cocoons on the bottom. Old Bill Nation designed an excellent fly pattern to imitate the pupae.
