Susan's purse-making caddisfly (Ochrotrichia susanae)
The U.S. Fish and Wildlife Service has completed a status review of Susan’s purse-making caddisfly, a small moth-like insect, and has determined it does not warrant protection as a threatened or endangered species under the Endangered Species Act. The Service made this finding after a thorough review of all the available scientific and commercial information regarding the status of Susan’s purse-making caddisfly and the potential impacts to the species.
Susan’s purse-making caddisfly has only been documented at three sites: Trout Creek Spring in Chaffee County, Colorado; High Creek Fen in Park County, Colorado; and Jaramillo Creek in Valles Caldera National Preserve, New Mexico.
The Service assessed potential impacts to Susan’s purse-making caddisfly including grazing, hazardous fuels reduction using prescribed burns and logging, roads, dewatering of spring habitats, recreational activities, climate change, collection, disease or predation, the inadequacy of regulatory mechanisms, genetic effects from small population size, and naturally occurring random events. The Service does not believe Susan’s purse-making caddisfly is in danger of extinction throughout all or a significant portion of its range because of current or future impacts.
