Endangered and Threatened Wildlife and Plants; 90-Day Finding on a Petition To List Thorne's Hairstreak Butterfly as or Endangered

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to list Thorne's hairstreak butterfly (Callophrys [Mitoura] grynea thornei or Callophrys [Mitoura] thornei) as endangered under the Endangered Species Act of 1973, as amended and to designate critical habitat. We find the petition and information currently available in our records presents substantial scientific or commercial information indicating that listing Thorne's hairstreak butterfly may be warranted. Therefore, with the publication of this notice, we are initiating a status review to determine if the petitioned action is warranted. To ensure that the status review is comprehensive, we are requesting scientific and commercial data and other information regarding this species. Based on the status review, we will issue a 12-month finding on the petition, which will address whether the petitioned action is warranted, as provided in section 4(b)(3)(B) of the Act.
