Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) The Monarch butterfly is attaining near worldwide distribution ion suitable places, but is primarily a species of the Americas. Autumnal migrants occasionally stray to Europe including England; the species has been spread widely in the Pacific Ocean area and is well-established in Australia. However, essential overwintering areas for North American populations are limited to a few dozen places in coastal California and the mountains of Mexico. A few adults apparently occasionally overwinter elsewhere including southern Florida but migrational status of these can be questioned. Adults can tolerate some cold and there is an early January record as far north as Cape May, New Jersey where sightings in December are fairly common. Such records in very late fall and early winter do not indicate overwintering potential. Most of the southern United States experiences lethally cold temperatures in many to all winters and old suggestions of regular overwintering in the Gulf states for example were unfounded.
