October Caddis Pupa

The October Caddis Pupa is a large, highly specialized subsurface fly pattern engineered to mimic the transitional pupal stage of the Limnephilidae family (specifically Dicosmoecus), commonly known as the giant orange caddis. This hatch is a legendary fall event on trout rivers—particularly across the Western United States—representing one of the last chances for trout to gorge on a massive, protein-rich meal before winter dormancy sets in.
