A pause in breeding that helps monarchs save energy in winter |
In mid-August, the first waves of monarch butterflies started their long flight into Mexico, with fresh sightings over Tamaulipas, Coahuila, and Nuevo León as they head toward the cool, misty fir forests of Michoacán and the State of Mexico to spend the winter until March. By late September, people across Oklahoma, Kansas, Missouri, and Texas reported the orange-and-black travelers riding favorable winds south, a pattern that marks the turning of the season each year. These sanctuaries offer a stable mix of temperature and humidity that monarchs need to survive the colder months, which is why the same mountain forests become a living, fluttering blanket every fall.
During this journey, monarchs enter reproductive diapause, a temporary pause in breeding that conserves energy and extends their lifespan through winter, allowing them to focus on flight, shelter, and feeding. The fir canopy helps them avoid freezing nights while staying humid enough to prevent their delicate bodies from drying out. When sunshine returns after cold mornings, clusters loosen as butterflies warm their flight muscles and glide to nectar sources, saving energy as they continue toward the high-elevation wintering grounds.
Communities along the route are pitching in: planting nectar-rich flowers and milkweed, setting out water stations, and creating pollinator gardens, including in places like Gómez Farías near the El Cielo Biosphere Reserve. Gardeners favor plants such as Gregg’s blue mistflower, which can fuel migrants during critical stopovers. Culture joins science in late October at the Monarch Butterfly Cultural Festival, where people celebrate the arrival of the monarchs and connect their return with Día de Muertos traditions, reminding everyone that conservation is both ecological and cultural.
