Each autumn, millions of monarch butterflies embark on an incredible journey from eastern North America to the oyamel fir forests of central Mexico. This annual migration, spanning up to 3,000 miles, is a marvel of ecological adaptation. To survive the long flight, the butterflies rely on thermal updrafts to glide efficiently, conserving their limited energy. They also eat a ton of nectar from wildflowers along the way, fueling their long flight. This critical stopover behavior highlights the importance of conserving nectar-rich habitats across their migration corridor.
