From 2003: Saving the Miami Blue butterfly

In this report which originally aired on April 13, 2003, “Sunday Morning” anchor Charles Osgood reports on efforts made by butterfly enthusiasts and scientists from the University of Florida to bring back from the brink a rare subspecies of butterfly, for years thought extinct until one colony was found in the Florida Keys. [Update: In 2011 the Miami Blue butterfly won emergency protection under the federal Endangered Species Act, and received formal protection the following year.] Source
