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.
In the summer Monarch habitats are found throughout the USA & Canada, including Vermont. Monarchs migrate to Mexico for Winter. In the last 25 years, illegal logging has destroyed 75% of the winter habitat for the monarch butterfly. The monarch butterfly population is down over 90% in both North America & Mexico due to habitat destruction. Thatâs a loss of over 900 million butterflies since the 1990s.
