This particular caddisfly is found in and near streams of North America, from northern California and Colorado to British Columbia and as eastern to Nevada, Idaho, Montana and Alberta. D. gilvipes is commonly known as the October Caddis, Autumn Caddis or Giant Orange Sedge, due to their flying presence acknowledged in the Autumn. Caddisflies are known to build cases when they are in larvae stages, to protect themselves from predators, such as dragonflies, salmon and trout. The October Caddisfly is no different and builds their cases out of different organic materials during their five larvae stages.
