Every year, monarch butterflies fly from Northern Canada to Mexico. Although they live all around the globe, but annually they make a noteworthy migration in North America. They are dutifully following this migration pattern for several years.
Recently, scientist offered some really significant information related to the migration of monarch butterflies. They presented a report that suggests that there is a special gene in all these butterflies which compels them to migrate. Collagen is the name of that gene, which form flight muscles in these butterflies.
Moreover, the study proposed that the cause behind the color of these butterflies. Generally, these monarchs are orange and black, but some of them are also white and black. The orange and black color of butterfly gives a hint to predators that they are extremely bad in taste and are really toxic to eat.
Marcus Kronfost, the main author of this research stated that almost one billion monarch butterflies migrated towards Mexico in 1996. Previous year, nearly 35 million monarchs traveled to North America. This figure indicates that the number of monarch migration has dropped in the past few years.
The activities of human beings are the chief reason behind this awful fall in the monarch migration. There are certain human activities that lead to climate changes which affect the migration process of monarch butterflies.
