Maintained by the US Geological Survey (USGS), this modest site is a nice starting point for younger users interested in butterflies. All users, however, will enjoy the butterfly photo gallery, which offers pictures of common butterflies from around the world, organized by continent. The section currently contains thumbnail images of butterflies from Western Europe and Britain and North America, with sections on Central and South America and Asia. Other features at the site include a coloring page on the Monarch life cycle, an illustrated butterfly and moth life cycle, butterfly and moth FAQs, and a large collection of (annotated) related links.
