As they travel, the butterflies breed and lay eggs on milkweed plants in Texas. Over several generations, the monarchs complete their migration and return to Mexico for the winter, making their trip one of the longest migrations on Earth.
However, because of extreme drought conditions, Texas’ milkweed population has declined in recent years, severely impacting the flight. The loss of milkweed and habitat, coupled with intense heat, contribute to the diminishing migration numbers over the past decade. More than 20 percent of the migration has decreased.
As part of preservation efforts, proceeds from the film will be donated to Mexico’s leading conservation organization, Fondo Mexicano para la Conservación de la Naturaleza.
