Endangered and Threatened Wildlife and Plants; Threatened Species Status with Section 4(d) Rule for Hermes Copper Butterfly and Designation of Critical Habitat

We, the U.S. Fish and Wildlife Service (Service), determine threatened species status under the Endangered Species Act of 1973 (Act), as amended, for the Hermes copper butterfly (Lycaena [Hermelycaena] hermes), a butterfly species from San Diego County, California, and Baja California, Mexico. We also designate critical habitat. In total, approximately 14,174 ha (35,027 ac) in San Diego County, California, fall within the boundaries of the critical habitat designation. This rule adds the species to the List of Endangered and Threatened Wildlife. We also finalize a rule under the authority of section 4(d) of the Act that provides measures that are necessary and advisable to provide for the conservation of this species.
