This nymph pattern is meant to imitate a cased caddis. The colors used should be matched to the cased caddis you see in your home waters but brown, olive, or green are common. Their segmented abdomen is usually protected by a portable house they build from debris found along the stream bed allowing just their head and 3 pairs of legs exposed. These are a major fish food source and are always on the menu.
