Monarch butterflies are known for their long annual migration. In North America, they make large migrations towards the south starting in August until the first frost. A migration towards the north takes place in the spring. No single individual makes the whole round trip.
There are three species of monarch butterflies: 1  D. plexippus, described by Linnaeus in 1758, is the species known most commonly as the monarch butterfly of North America. 2  D. erippus, the southern monarch, was described by Pieter Cramer in 1775.
