Action timeline

June 15, 2000 – The North American Butterfly Association petitioned the U.S. Fish and Wildlife Service to list the Miami blue under the Endangered Species Act on an emergency basis. The Service found that listing “may be warranted.” Under the Act, the Service was required to issue a listing determination by June 2001.

June 2, 2005 – The Service failed to grant the Miami blue endangered status under the Endangered Species Act, claiming that listing was “warranted but precluded.” The Center challenged this determination by filing notice of intent to sue.

August 29, 2001 – The Center and two other environmental organizations reached an agreement with the Service to expedite the protection of 29 species, including the Miami blue, under the Endangered Species Act.
