Briefing: Mexico’s monarch butterfly population jumps 64%, offering hope for at-risk species

This winter, the population of monarch butterflies in Mexico increased by 64% compared to the same period in 2025, marking a notable recovery for the species.

The area covered by these butterflies is the largest recorded since 2018, indicating potential improvements in habitat conditions or conservation efforts.
