ETWP; 90-Day Finding for a Petition To List the Miami Blue Butterfly as Endangered With Critical Habitat; Substantial

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding for a petition to list the Miami blue butterfly (Hemiargus thomasi bethunebakeri) under the Endangered Species Act of 1973, as amended. The range of this butterfly, which once extended north along the Florida coasts to about St. Petersburg and Daytona, has been shrinking for many years. We find that the petition presented substantial information indicating that listing this species may be warranted. We are initiating a status review to determine if listing the Miami blue butterfly is warranted.
