The Butterfly WebSite has on ongoing project to provide a World Atlas of Butterflies and Moths. Since creating a massive worldwide database is beyond our resources, we've produced a constantly-growing database covering the world. For the United States and United Kingdom, the following links provide extensive coverage. More specific coverage for these areas, as well as other areas of the world, are included below.
