Monarch butterfly, 帝王斑蝶

Monarch butterflies rest on a pine tree in Angangueo, Mexico, November 28, 2015. Thousands of striking orange and black monarch butterflies began arriving to their winter home in central Mexico on Saturday (November 28) in their annual migration. The 4,800-kilometre mass migration of monarch butterflies in North America is one of the insect world's fantastic feats, with millions embarking on the arduous journey from as far north as Canada down into Mexico and the California coast each autumn.
