The Migration of Monarch Butterflies is the world rarest phenomenon. The Mexican mountain where orange, black Monarch butterflies gather in countless numbers. They cover 10 ACRES after a 3,400-mile journey from the U.S. where they’ve earned a rest. The butterflies travel down from the United States and Canada to spend winters in the mountains west of Mexico City where they are counted by biologists. Unfortunately, the population of Monarch butterflies has been in serious decline in recent years.
But thanks to conservation efforts by the Canadian, Mexican and American governments. They are putting great efforts to increase the insects have been making a big comeback. The Monarch butterflies’ habit of congregating in thick clumps are counted by the surface area they cover instead of individually. The population has grown up since 2014 after a threatening drop as compare to the previous decade.
In the last winter, the population had increased in significant numbers covered 10 acres, as compared to 2.8 acres of 2014. The lowest population was recorded in 2013 when only 1.66 acres covered. Millions of butterflies congregate, clustering onto pine and oyamel trees, appear orange and branches sag from the weight. These butterflies over the time to make this journey, four generations of monarch butterflies are born and die migration patterns are altered by climate change.
The nature lovers believed Mexico, United States, and Canada should enhance their conservation efforts to protect and restore the habitat of this butterfly along its migratory route. Moreover, in recent times, United States is working to reinstate milkweed, a plant important to the butterflies’ migration, on about 1,160 square miles within 5 years, both by planting and by designating pesticide-free areas.
In addition, it is also cracking down on illegal logging in the area the butterflies call home, as the trees are critical protection for the flimsy animals against the weather. During the Migration of Monarch Butterflies, they fly north once they are exposed to cooler temperatures. Therefore, dense congregations are supposed to conserve heat, however, if warmed by the sun, the butterflies take flight.
Moreover, the beating of their wings has been compared to the sound of light rain and the reserve is susceptible to lethal, freezing temperatures. The nature lovers truly love the Migration of Monarch Butterflies every year.
