Fish and Wildlife Service September 4, 2012 – Federal Register Recent Federal Regulation Documents

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list four subspecies of Great Basin butterflies (White River Valley skipper (Hesperia uncas grandiosa), Steptoe Valley crescentspot (Phyciodes cocyta arenacolor), Baking Powder Flat blue butterfly (Euphilotes bernardino minuta), and bleached sandhill skipper (Polites sabuleti sinemaculata)) in Nevada as endangered or threatened species and designate critical habitat under the Endangered Species Act of 1973, as amended (Act). After review of the best available scientific and commercial information, we find that listing these four butterfly and skipper subspecies is not warranted at this time. However, we ask the public to submit to us any new information that becomes available concerning the threats to the White River Valley skipper, Steptoe Valley crescentspot, Baking Powder Flat blue butterfly, and bleached sandhill skipper or their habitats at any time.
