It is perhaps the best known of all North American butterflies. Since the 19th century, it has been found in New Zealand, and in Australia since 1871, where it is called the wanderer.
Among the two species of Monarch butterflies, the one in North America differs from the one you will find in South America, but the Caribbean is home to both species. You can also see them in Australia, New Zealand, and several Islands lying between Australia and Tahiti, in parts of Europe and in Hawaii.
