Our mission as an international nonprofit organization is to protect wildlife through the conservation of invertebrates and their habitats. We take our name 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 Society is a science-based conservation organization.  Our core programs focus on habitat conservation and restoration, species conservation, protecting pollinators, contributing to watershed health, and reducing harm to invertebrates from pesticide use. 

Over the past four decades, we have protected endangered species and their habitats, produced ground-breaking publications on insect conservation, trained thousands of farmers and land managers to protect and manage habitat, and raised awareness about the invertebrates of forests, prairies, deserts, and oceans.
