Monarch butterflies that fly thousands of miles from the U.S. to Mexico aren’t your average summer flutterers—they’re part of a special Methuselah generation that lives up to nine months, way longer than the usual two to six weeks! These long-lived travelers make the entire migration south in one go, while it takes several generations to return north. Scientists still don’t fully understand how these butterflies pull off such a feat, but their ability to pause reproduction until the journey’s end is a big part of the mystery. What do you think makes these monarchs so unique? #Pets #MonarchButterflies #Migration
