This was taken on Martha’s Vineyard in early October. Not this one but I watched other Monarchs heading off out over the open water. Monarchs are especially noted for their lengthy annual migration. They make massive southward migrations from August through October. The length of these journeys far exceeds the lifetime of most Monarchs, which is less than two months for butterflies born in early summer. The last generation of the summer lives up to 7 months, during which it flies to the overwinter location. This generation does not reproduce until it leaves the overwinter location the following spring, but it is actually this generation’s children and great-grandchildren that return to their northern location in the spring.
