Caddis larva are available to trout year round. The Green Rock Worm caddis imitation has very few steps, and is a very easy fly pattern to tie. It can be used as a searching nymph, or to match the available food types in a given stream. It is bright and catches the attention of fish, so it can be used effectively as a lead fly in a tandem nymph rig to attract the fish that often will then take the small trailing realistic pattern. However, don’t let that fool you. This pattern represents free-living caddis and takes picky trout on very tough rivers. Here in Utah, Provo River fly fishing guides often tie up and fish this pattern because it is so easy and so effective. Let us know of your success!Recipe:
