From The Pueblo Chieftain (Tracy Harmon):
The Susan’s purse-making caddisfly is found only in Trout Creek Spring area of Chaffee County and in High Creek Fen in Park County.
The petition was submitted by the Xerces Society, Center for Native Ecosystems, WildEarth Guardians and Western Watersheds Project. It asserts that grazing, logging and other activities affect Susan’s purse-making caddisfly habitat.
Here’s the release from the U.S. Fish & Wildlife Service.
