Endangered and Threatened Wildlife and Plants; Endangered Species Status for the Fluminense Swallowtail Butterfly, Harris' Mimic Swallowtail Butterfly, and Hahnel's Amazonian Swallowtail Butterfly

We, the U.S. Fish and Wildlife Service (Service), determine endangered species status under the Endangered Species Act of 1973 (Act), as amended, for three butterflies endemic to Brazil: the Fluminense swallowtail (Parides ascanius), Harris' mimic swallowtail (Eurytides (=Mimoides) lysithous harrisianus), and Hahnel's Amazonian swallowtail (Parides hahneli). This rule extends the Act's protections to these species.
