Monarchs are especially noted for their lengthy annual migration. They make massive southward migrations from August through October. A northward migration takes place in the spring. Female Monarch butterflies deposit eggs for the next generation during these migrations. The population east of the Rocky Mountains overwinters in Michoacán, Mexico, and the western population overwinters in various sites in central coastal California, United States, notably in Pacific Grove and Santa Cruz.
