Butterflies are valuable components of our environment. From the grassland-dependent species of the Pacific Northwest to swallowtails of Central and South America, we work to conserve butterflies and moths throughout the world. The Red List of butterflies and moths assessed the conservation needs of some of the most at risk North American species. The Xerces Society works with state and federal agencies, landowners, and other nonprofit organizations to achieve effective Lepidoptera conservation.
