Scientists fitted nearly 1,750 monarch butterflies with tiny solar-powered trackers

In an innovative effort, researchers have equipped around 1,750 monarch butterflies with solar-powered trackers to study their extensive migration patterns. This advanced tracking technology offers insights into their traveling habits, including routes, daily distances, and resting points. Every year, these butterflies journey from Canada and the US to Mexico, and recent discoveries highlight the links between migration patterns and North American populations.
