Western Monarch Day

Western Monarch Day is an annual American holiday created to raise awareness about the Western Monarch butterfly. Today, the species is endangered, with only about 10% of its population remaining. The holiday is observed every year on February 5.

History

Western Monarch butterflies are a captivating sight, with large wings featuring intricate patterns in shades of red, gold, yellow, and other vibrant colors. These butterflies are among the most effective pollinators and are known for their remarkable continental migrations.

It is believed that Monarch butterflies originally lived in American rainforests. As milkweed— their primary food source—spread, Monarchs began to inhabit more regions. These intelligent creatures have biological mechanisms that guide their migrations. Each year, with the arrival of winter, they migrate from the western United States and Canada to the southern states, mainly California, where conditions are ideal for their survival.

Monarch butterflies have been studied since the mid-19th century, but their migratory patterns were only confirmed in the 1970s. Western Monarch Day was established in California in 2004 to promote tourism and raise public awareness about this beautiful but endangered species.
