“The population of monarch butterflies in Mexico increased 64% this winter, compared with the same period in 2025, offering a glimmer of hope for an insect considered at risk of extinction.

The figures, released this week by the World Wildlife Fund (WWF) Mexico, showed that the area occupied by monarchs expanded to 2.93 hectares (7.24 acres) of forest from 1.79 hectares (4.42 acres) the previous winter, the largest coverage since 2018.”
