The story

National Start Seeing Monarchs Day, observed on First Saturday of May, is a special occasion that heralds the arrival of monarch butterflies in North America. As these vibrant insects embark on their extensive migration journey from central Mexico to the southern United States, enthusiasts across the country prepare for their return. This day not only celebrates the beauty of monarchs but also raises awareness about the challenges they face during their migration.

Read the full story

The tradition of observing this day began in 1995, initiated by Monarch Watch, a nonprofit organization dedicated to the study and conservation of the monarch butterfly. With a mission to educate people on the importance of butterflies and their habitats, Monarch Watch encourages communities to participate in activities that promote butterfly conservation. Over the years, this initiative has grown, inspiring thousands to engage with nature and protect these delicate creatures.

Monarch butterflies are renowned for their incredible migration journey, which can span over 3,000 miles. Each year, millions of these butterflies travel from their wintering grounds in Mexico to the warm summer habitats in the United States and Canada. Unfortunately, only about 5% of these butterflies survive the perilous journey, facing threats such as habitat loss, climate change, and pesticide use. National Start Seeing Monarchs Day serves as a reminder of the importance of protecting their migratory routes and breeding grounds.

As spring approaches and the weather warms, many people partake in activities to celebrate National Start Seeing Monarchs Day. Families, schools, and communities come together to plant milkweed gardens, host butterfly walks, or participate in citizen science projects. By fostering a greater understanding of these insects and their habitats, we can help ensure that future generations will also experience the wonder of seeing monarch butterflies in flight.
