Greater Fritillaries are a genus of butterflies that are also known as “silverspots” due to the silver spots many of them have beneath their hind wings. Greater Fritillaries in New England include the Great Spangled Fritillary , the Aphrodite Fritillary and the Atlantis Fritillary. It can be challenging to tell these three orange-dappled species apart. The black margins on the upper side of the pictured Atlantis Fritillary’s wings help identify it. This fritillary is named after Atlantis, a legendary island first mentioned by Plato. While adult Atlantis Fritillaries favor the nectar of milkweed, thistle, burdock and boneset, the brown and black-speckled larvae feed on violets.
