Western Monarch Day

Western Monarch Day on February 5 transports us to a different realm, filled with the vibrant flutter of Monarch butterfly wings. This special day celebrates the Monarch butterfly’s remarkable journey back to California from across the western U.S., marking part of their seasonal migration. This natural event draws countless visitors to parks and areas where these colorful insects gather. While Monarchs are not confined to one location, this day focuses on their return to the California coast, crucial as their numbers are alarmingly dwindling.

History of Western Monarch Day

Western Monarch butterflies, with their striking red, orange, yellow, and gold colors, are a captivating sight as they glide through landscapes to pollinate. Originating from the American Tropics, these butterflies spread as milkweed, their main food source, expanded, leading to the sophisticated migration patterns seen today. Every winter, Western Monarchs from the U.S. and Canada journey to California, ensuring better survival rates. Their offspring then make the trip in subsequent years, a pattern discovered only in the 1930s despite studies starting in the 1850s. Canadian zoologist Frederick Urquhart and over 3,000 butterfly enthusiasts tagged Monarchs across North America, uncovering their migration route southwards. A key moment in 1973 came when Kenneth Brugger, a businessman, observed Monarchs during a Mexican hailstorm, leading to the discovery of their wintering site on the Trans-Mexican Volcanic Belt. With such a large migratory spectacle and the butterflies remaining from October to March, California declared February 5 as California Western Monarch Day in 2004 to boost tourism and awareness. However, Western Monarch numbers have been declining due to deforestation, pesticide use, climate change, and other issues yet to be fully explored. Their population has dropped by a staggering 90%, and conservation groups are striving to prevent extinction.
