The monarch butterfly, also known as the black-veined golden spotted butterfly, is a larger butterfly known for its bright orange and black markings. The wingspan is between 9.5 and 10.5cm, and the weight is between 0.25 and 0.75 grams. The most notable feature is their large-scale migration behavior. Every autumn, they fly from Canada and the northern United States to the forests of central Mexico to spend the winter. This migratory behavior is one of the most spectacular phenomena in the insect world. The larvae feed on milkweed, a plant that contains toxins that gives monarch butterflies some defense against predators. The adults feed on nectar, have strong flight ability and long migration distance.
