Tracking Monarch Butterflies Migration
The fall migration of monarch butterflies is currently underway, with millions traveling up to 3,000 miles to overwinter in Mexico or southern U.S. states. Monarchs follow shoreline routes and utilize air streams to aid their journey, which can reach speeds of 10-30 mph. Although not officially listed as endangered, their population faces threats from habitat loss, climate change, and agricultural development, leading to their classification as "threatened." The last generation of the year lives longer, up to nine months, to complete the migration cycle.
