The red admiral, Vanessa atalanta, is a common butterfly in many parts of the world. It can be found through out most of North America except for the extreme northern portions of Canada and Alaska. They can also be found in Europe, Asia, Africa, New Zealand and Central America.
In the warmer portions of their range they fly all year long. In the northern portions of their range they will migrate south for the winter. This means that each year many of the young butterflies that emerge from their chrysalis' in the south will travel north to repopulate the northern portions of their range.
