The butterflies have always been part of our culture, says Gloria Fermina Tavera Alonso, director of the Biosphere Reserve of the Monarch butterfly.
The orange of their wings, the sound when they fly, it's like therapy, Gloria Fermina Tavera Alonso says. After all the years in her job, she still wonders how the small and light creatures manage to get to the park every year. "They are threatened by so many things! But they travel in a group, so they protect each other."
