WASHINGTON (CN) – The U.S. Fish and Wild Life Service has determined, after a 12 month status review, that there is insufficient information to warrant protecting the Susan’s purse-making caddisfly under the Endangered Species Act.
The status review was based on a petition from the Xerces Society, which argued that the species is seriously threatened by habitat loss, primarily due to the effects of livestock grazing and timbering projects.
The Susan’s purse-making caddisfly was identified as a new species in 1976, and has only been found in two sites in central Colorado.
The agency determined cattle grazing, tree cutting, road building and other activities mentioned in the Xerces Society petition have not shown a negative impact on caddisfly breeding locations and are too far away from those locations to pose a threat to the survival of the fly in the immediate future.
