The Xerces Blue butterfly (Glaucopsyche xerces) was native to the coastal dunes of San Francisco, in the United States. As the city grew, much of the butterfly’s habitat was destroyed and its population was relegated to Golden Gate National Park. Its wings were a deep iridescent blue, with characteristic white spots on the ventral side.
