The Monarch Butterfly must travel more than 4 thousand kilometers to reach Mexico

The life of the monarch butterfly begins in a plant called asclepia , where the eggs are deposited. The history of the monarch butterfly continues after 4 to 12 days, when a caterpillar emerges from the same plant on which it was born and develops into a strong winged adult.

The life of adult monarch butterflies lasts four to five weeks for generations born during spring and summer (which will spend their entire lives in the north). However, the generations born in September or early October, give rise to winter adults, whose life span increases from six to seven months. The decrease in temperature and periods of sunlight determine that they delay their sexual maturity from six to seven months approximately, entering a reproductive pause. It is at this time when the monarch butterfly route begins in scattered form: a population part of the western US towards the coasts of California; and another in the northeastern US and southeastern Canada migrates to the south of the continent. Therefore, they are called migratory generation, and it is the one that comes year after year to the Monarch Butterfly Biosphere Reserve in the Mexican Republic.

Monarch for Mexican lands

Monarchs in Mexico enter a broad strip of approximately 500 km, which stretches from Chihuahua and Coahuila to Nuevo Laredo in Tamaulipas. They cross a good portion of the Chihuahuan Desert and arid zones of the central highlands where they are able to locate vegetation patches which they use as resting places.

The monarch butterfly season and its arrival to the winter habitat (the Monarch Butterfly Biosphere Reserve) begins during the last days of October, establishing numerous clusters or hibernating colonies that remain there until the first months of the following year ( mid-March) when the temperature begins to rise. This is how the monarchs interrupt their pause to mature sexually and begin to mate and then return to the northern territories of the continent.

The cycle continues

Since the beginning of the dispersion From where the monarch butterflies live until their establishment in their spring and summer habitat, basically they happen around 5 generations of butterflies, of which, the last one will hatch between September and principles of October and will constitute the new migratory generation that will repeat the wonderful migration to the southern territories. The distance between its spring and summer habitat surrounds the 4,500 kilometers , which can be covered up to a speed of 120 kilometers per day . A true phenomenon of nature that fortunately happens in our country!

Migration path of the Monarch Butterfly

The life of the monarch butterfly begins at a plant called milkweed, where the eggs are deposited. The story of the monarch butterfly continues after 4 to 12 days when a caterpillar emerges that feeds on the same floor where he was born and which develops into a strong winged adult.

Four to five weeks for the generations born during spring and summer (which spend their entire life in the north). However, the generations born in September or early October, giving rise to winter adults, whose lifetime is increased from six to seven months. The decrease in temperature and periods of sunlight delay sexual maturity approximately six to seven months reproductive entering a pause; It is at this time when the path of the monarch butterfly begins to scattered: the population of the western United States to the coast of California; And over the northeastern United States and southeastern Canada migrates south of the continent.
