There are a variety of natural caddis pupa larva available to the trout in many stocked trout streams. Big Stoney Creek West of Edinburg and the Hidden Valley of the Jackson have especially large caddisfly populations. I like to fish a two or three fly rig on the streams by starting right below the riffles and in the tails of the pools. Retrieve these with a slow twitching action. Good flies are the Murray's Olive Magic Caddis Pupa size 14, Murray's Tan Magic Caddis Pupa size 14 and Murray's Caddis Larva size 14.
