Do Monarchs occur outside of North America?
Yes. Monarchs are found at middle elevations in many places in central and south America. Although not well studied in these areas, there are some indications that Monarchs migrate to dryer areas when the wet season begins and then back to wetter areas when the dry season becomes so severe the host plants die back. In the last century Monarchs were introduced, evidently by ship traffic, to the Azores, Australia, New Zealand, Hawaii and many Pacific islands. More recently a limited population of Monarchs has become established in southern Spain.
