The area occupied in Mexico by monarch butterflies after their migration this year is 69 percent larger than in the previous season, but still among the smallest in recent decades, the World Wildlife Fund said.

During the fall, monarch butterflies migrate from Canada and the northern United States to Mexico and this year they are spread across 1.13 hectares (2.8 acres) in the states of Mexico and Michoacan, compared with 0.63 hectares (1.55 acres) in 2014.
