Xerces Society Inc.
The Xerces Society for Invertebrate Conservation is an international nonprofit organization that protects the natural world through the conservation of invertebrates and their habitats. Our name (which is pronounced Zer-sees, or /ˈzɚˌsiz/) comes from the now-extinct Xerces blue butterfly (Glaucopsyche xerces), the first butterfly known to go extinct in North America as a result of human activities. The Xerces blue's habitat was destroyed by development in the sand dunes of San Francisco, and the species was declared extinct by the 1940s.
