Every year, millions of Monarch butterflies make the journey south to mate. At what is called, overwintering sites, millions of butterflies will gather to mate and wait out the cold temperatures further north. Because Monarch’s are ectothermic, meaning they rely on the heat of the sun to be active (mate and eat), warm temperatures are a necessity—and it also leads to one of the most beautiful instances of white noise we have ever heard.
During the day, thousands of butterflies will rest on a tree as they wait for the sun to warm them and give them the energy to eat and mate. When they have warmed up enough, in a waterfall of flight they leave their resting spot, making one of the most beautiful sounds of nature you will ever hear. Don’t believe us? Just watch the video and hear for yourself. —ML
