The Monarch butterfly (Danaus plexippus) is a well-known North American butterfly. Its wings feature an easily recognizable orange and black pattern. The females have darker veins on their wings, and the males have a spot in the center of each hindwing from which pheromones are released. Monarchs are especially noted for their lengthy annual migration. They make massive southward migrations from August through October, and a northward migration takes place in the spring.
