Butterflies are cold-blooded creatures, meaning they rely on outside sources to keep their bodies warm. They can’t handle cold weather and need to head down south to follow the sun! In addition, they need to follow their food source. If there are no more flowers, it’s time to move on. While everyone knows that the monarch migrates, so do many other types of butterflies, including the painted lady, red admiral, common buckeye, and many more. The monarch migration usually begins in October but can happen earlier if it’s cold. Butterflies can even migrate in warm climates. This ensures they form new colonies and spread out so that all their food sources aren’t depleted.
