Arrival and Traditions
Every year monarchs arrive around the first of November, as the rainy season ends and it's time to harvest corn. The arrival carries special meaning and is tied to Mexican traditions, culture, and seasons.

"For us, the arrival of the monarchs symbolizes our ancestors' souls returning to Earth for their annual visit on the Dia de los Muertos (Day of the Dead). The monarchs arrive each fall as we honor our ancestors, harvest our crops, and mark the passing of another year," says Estela Romero.
