The San Francisco Bay Area is home to around 144 species of butterflies. You can find them in all types of habitats including urban areas. The Bay Area has the highest density of endangered butterfly species in the nation. The Western Pygmy Blue is the smallest butterfly in the United States. The Monarch over-winters in large numbers at several Bay Area locations. The Gulf Fritillary is a non-native species that has successfully colonized parts of the East and South Bay.
