The annual Fall monarch butterfly migration sees hundreds of millions of orange-winged insects traveling upwards of 30 miles a day to Mexico, in a colourful mass of aerial delight.
On these over-wintered grounds one can witness mass convergence of monarch butterflies hanging from trees in clumps like dense leaves. Numbers can reach as many as 50 million butterflies on an area of land a little smaller than two-and-a-half soccer fields.
A magical spectacle to behold in this clip from National Geographic’s upcoming Great Migrations series, monarchs open their eyes, stretch their wings and celebrate springs sexual awakening.
