Endangered Status The Uncompahgre Fritillary, a subspecies of the Dingy Fritillary, is on the U.S. Endangered Species List. It is classified as endangered in Colorado. This butterfly is known to live only among Snow Willow Plants above 12,000 feet elevation in a few places in the San Juan Mountains and the Sawatch Range. Sadly, this and other butterflies that live in small and isolated populations have suffered at the hands of humans, namely collectors. The rarer a species is, the more it is coveted for collections, and this butterfly's low, slow flight makes it an easy catch. It has been listed as an endangered species since 1991, and it is illegal to collect or otherwise molest it. Researchers are surveying the butterfly's range in the hopes of finding other populations, and studying the species habitats and life cycle. There have been reports of other populations existing, but their discoverer has chosen to keep the locations a secret.
Habitat Alpine & subalpine habitats, Arctic habitats.
Range Alaska, Rocky Mountains, Western Canada.
