Two butterflies declared extinct in USA

Zestos skipper butterfly & Rockland grass skipper butterfly declared extinct

June 2013. Officials from the U.S. Fish and Wildlife Service (USFWS) have declared two species of butterfly as officially extinct. Both butterflies were previously found in South Florida, but have not been seen for 9 and 13 years respectively, despite extensive searches.
Zestos skipper butterfly - Not seen since 2004
The Zestos skipper butterfly has not been seen since 2004. The Zestos skipper was last recorded in the Florida Keys in 2004, but hadn't been seen for several years before that on the mainland. The Zestos skipper wasn't thought to be Endangered as it was widespread throughout the Bahamas. However it was recently discovered that the Zestos skipper in Florida was a distinct subspecies; sadly it was probably already extinct when that discovery was made.
Rockland grass skipper butterfly - Not seen since 2000
The Rockland grass skipper was last seen in the Everglades National Park in 2000.
