Climate change is impacting migration of Monarch butterflies

The annual migration of thousands of monarch butterflies to Mexico will be delayed this year, likely due to climate change, experts say. Monarchs typically migrate up to 2,000 miles from the eastern U.S. and Canada to Mexico by late October. This year, they did not begin arriving until mid-November, according to biosphere reserve director Amado Fernandez. The delay is likely due to warmer weather in the north which can ultimately put the butterflies out of sync with the flowering of plants they rely on for food in Mexico. Last winter, the monarch population in Mexico fell by nearly 60%, according to Mexico’s National Commission of Protected Natural Areas. Experts also say herbicides and pesticides use along their migratory route have harmed their breeding habitats and health.
