According to a statement released by Mexico’ ministry of environment, it would seem that the number of monarch butterflies is increasing. Monarchs return to Mexico after authorities have struggled to preserve their population.
The monarch butterfly comes from a family of butterflies named Nymphalidae. The butterfly is easy to recognize by its wing patters, which contains the color black, orange and white. The monarch has a wing-span of approximately 10 centimeters.
Usually, each year the population of monarch butterflies from the United States and Canada migrates to Mexico. This migration usually takes place in late-summer or in autumn.
But it seems that, over the years, the population of monarch butterflies has been declining due to massive deforestations. Authorities came to believe that illegal logging might be the main reason why this species of butterflies is faced with extinction. However, it seems that major developments in the area of pesticide might have contributed to the monarch’s downfall.
Monarch butterflies usually prefer to amass in lush meadow, where they consume milkweed leaves. By spraying chemical pesticides, we manage to wipe out most of their major food source.
But is seems that the efforts to preserve this majestic species of butterflies are paying off. In an unprecedented wildlife action that involved environmental authorities from Canada, US and Mexico, the population of monarch butterflies has been stabilized.
According to the statistics, it would seem that the butterfly population has been severely affected. Back in the ‘90s, the authorities recorded over 1 billion monarch butterflies. After 13 year, the number have plunged ever further. In 2013, authorities only accounted for 35 million butterflies.
But hope is not entirely lost. Thanks to the efforts of the three major countries, this year we are to expect a number of over 50 million insects, migrating from Canada and US to Mexico.
Much has been learned from this distinguished flying insects. It seem that these butterflies are very resilient to environmental changes. A couple of year ago, some astronauts residing on the International Space Station wanted to conduct a biological experiment. The goal of the experiment was to determine if the Space Station is actually capable of allowing insects to breed. So, they brought aboard a couple of monarch butterflies and started their experiments.
The whole endeavor has proven to be very successful. The butterflies adjusted to their new environment and started to breed. Another interesting about the monarch butterflies is how they manage space orientation. Scientists don’t know for sure how they are able to orient themselves.
According to a couple of theories, it would seem that the butterfly uses either the Sun or the projection of magnetical waves on clouds in order to navigate.
