Monarch butterflies added to endangered list; scientists use solar-powered backpacks

To protect the endangered monarch butterfly, researchers are harnessing the power of tiny solar-equipped devices for monitoring.

These trackers provide valuable data on how butterflies interact with their overwintering habitats and locate nearby nectar sources.

With small radio telemetry devices attached to them, scientists can study these creatures more effectively in California's coastal areas.

Moreover, the initiative invites citizen scientists to contribute their own observations through an easy-to-use mobile application.
