USFWS proposes to list a subspecies of butterfly (Speyeria nokomis nokomis), a silverspot butterfly from Colorado, New Mexico, and Utah, as a threatened species under ESA, with a rule issued under section 4(d) of the Act ("4(d) rule"). This document also serves as their 12-month finding on a petition to list the silverspot. After a review of the best available scientific and commercial information, they find that listing the subspecies is warranted. If finalized this rule as proposed, would add this subspecies to the List of Endangered and Threatened Wildlife and extend the Act's protections to the subspecies. They determined that designating critical habitat for this subspecies under the Act is not prudent. They will accept comments received or postmarked on or before 5 July 2022.
