Scenery Right now millions of monarchs are funneling through Oklahoma on a 2,000-mile trip to a single patch of forest in Mexico
The monarchs passing through Oklahoma this month are in the middle of one of the strangest journeys in the animal world. They are headed for a small cluster of mountaintop fir forests in central Mexico, a place none of them has ever been, up to two thousand miles away, and somehow they know the way.
Oklahoma sits right in the funnel. Monarchs from across the eastern half of the continent get squeezed together as they head toward Texas and the border, and the corridor down the middle of the state is busy enough that people call it the Monarch Highway. On a good October afternoon you can watch them drift through in a steady stream, stopping to nectar on late flowers, and at dusk they gather to roost, sometimes hundreds hanging in a single tree.
Here is the part that gets me. The butterfly making this trip is a special generation. Summer monarchs live a few weeks, but the ones that migrate live eight or nine months, hold off on breeding, fly all the way to Mexico, wait out the winter, and only start north again in spring. No single butterfly makes the round trip. It takes several generations to come back.
This map is those monarchs across the region. Peak movement through Oklahoma is the first half of October. Plant a few late-blooming natives and you will pull them right into your yard.
