Seismology meets botany: Geologist applies vibration science to saguaros Guys it's been 5 mins and this butterfly is not flying from my hand, she is alive but she is not moving anywhere : r Butterflies Ever notice a monarch butterfly vibrating its wings? This isn't just random behaviorit's a survival strategy called Shivering. Especially when temperatures drop, monarchs vibrate their wings to generate heat and warm Why do monarch butterflies shiver? They do this to increase their body temperature by warming their muscles so they can take flight., Photo Courtesy of Community Member Julie Bthanks Julie! The moment she takes off and starts flying around their house @skylerstelz shared that despite butterflies having a very short lifespan, she was determined to see this butterfly fly again!
