Monarch butterfly is one of the most famous butterfly species in America. It is famous for its spectacular long-distance annual migration. Every winter, the monarch butterfly, which lives in the east of the Rocky Mountains in Canada and the United States, flies more than 4500 kilometers to Mexico. After a short rest, it continues to fly to the jungle of Butterfly Valley in Michoacan state, central Mexico, where it dies after wintering and breeding. Next spring, their offspring will return the same way.
The front of Monarch butterfly is similar to the bottom, the main body of the bottom is light yellow, the wing veins and edges are similar to the front, and the white spots on the bottom are larger than those on the front. There are some orange spots at the proximal end of the front wing. The color of the front wing is darker than that of the rear wing. There are four white spots symmetrically arranged on the upper edge of the front wing.
