Mushroom Jun's America's Wanderlust Mexico, Monarch Butterfly Valley Starting from Mexico City, after a one-hour traffic jam, there is an hour of isolated mountain road, spending another half an hour Riding the hills with the guides, and finally carefully walking to the mountain trails that the horses could not climb, finally arrived at Piedra Herrada Sancturay, the most recent monarch butterfly nature reserve in the capital city. Nearly 250 million monarch butterflies fly 4,828 kilometers per year across North America, spending four generations to complete the journey from the Great Lakes region of North America to Mexico. Before the second year of the migration in the winter, several generations of monarch butterflies born in the summer have already completed their lives, and the grandson who started the migration of butterflies in the previous year completed the journey. For no apparent reason, these new generations always know the route of migration and follow the same route that their ancestors have traveled sometimes even back to the same tree. Walk up and look up at the end of the road. The black coats on the fir trunks are all monarch butterflies. The treetops are also like the monarch butterflies. The monarch butterfly under the Yangguan began to take off the dance with the heat, and the monarch butterfly in the shadow immediately filled up. Mexico has a total of eight Monarch Butterfly Sanctuary, which is a very small travel route in the area. If you are impressed by the story of this butterfly migration, you must remember to take a look.
