## Abstract

We, the U.S. Fish and Wildlife Service (Service), are listing the Sacramento Mountains checkerspot butterfly (Euphydryas anicia cloudcrofti), a butterfly from New Mexico, as an endangered species under the Endangered Species Act of 1973 (Act), as amended. This rule extends the Act's protections to the Sacramento Mountains checkerspot butterfly. We will propose the designation of critical habitat for the Sacramento Mountains checkerspot butterfly in a future rulemaking.
