October Caddis Nymph

The October Caddis Nymph is a fly pattern specifically designed to imitate the nymph stage of the October Caddis (Dicosmoecus genus), a species of large caddisfly found in North America. This fly pattern is particularly effective during the fall months when October Caddis nymphs are active in rivers and streams. The body is often constructed using materials such as peacock herl, dubbed fur, or synthetic materials in appropriate colors to mimic the natural nymph’s appearance. The fly is commonly tied with a dark or mottled coloration to match the natural.
