Our application allowed us to identify that there are two routes that cross into the United States and that come to join Guanajuato before we reach the sanctuaries are the final stops; we want to double down on those efforts to promote recognition of what we call perch trees, which are more pollinating gardens, these trees that monarchs visit year after year, a compromise The fundamental part is to identify areas or areas that can be declared as municipalities or voluntary ANPs to preserve the treasure that we have, that heritage” Gave Assurance.

migration of monarch butterfly

The fourth generation is the one that migrates, named ‘Methuselah’. There are two migrations simultaneously, one from the east and the other from the west.

Eastern migration includes butterflies that breed in southern Canada and the United States east of the Rocky Mountains. These butterflies travel to overwintering sites in the states of Michoacán and Estado de México in central Mexico. The same individuals who arrived in Mexico (the Methuselah generation) make the return trip to the United States in early spring. This migration covers over 90% of the North American monarch butterfly population.

The western migration includes butterflies that breed from southern Canada and a portion of the United States west of the Rocky Mountains. These butterflies travel to various overwintering sites scattered along the California coast. The same individuals that reach California begin their return journey north in early spring. This migration covers less than 10% of the North American monarch butterfly population.

There is evidence that some butterflies may change routes and move from west to central Mexico to overwintering sites. The migratory generation lives between 8 and 9 months, while the other generations live for about a month.

In addition to migratory populations, there are also Monarch populations that do not migrate. They are located in southern Florida and throughout the Mexican Republic. The monarch butterfly has also been introduced to Australia, Hawaii, and other countries.

In the state of Guanajuato, it can be seen in 46 municipalities, but mainly in the eastern, southern and southern municipalities of the state such as: San Diego de la Union, San Luis de la Paz, San José Iturbide, Apseo el Grande , Apseo el Alto , Tarimoro, Acambaro, Jarecuaro and Tarandakuao.
