π± A jaw-dropping new technology now enables you to help track migrating monarchs from Canada to Mexico β and to see the paths of individual butterflies in precision detail β simply by downloading an app!
π¦ When this project was piloted last year, Monarch Joint Venture called it "the most comprehensive tracking study of monarch butterfly migration ever conducted" β and it's expanding to even more sites this migration season. Our friends at New Hampshire Audubon and the Vermont Center for Ecostudies have recently outfitted several monarchs with these tiny, ultralight trackers (with more to come!), so you could even encounter a local butterfly at the start of their epic journey. If you'd like to be part of this groundbreaking network, simply download the Project Monarch app (links in the comments), then start scanning for tagged butterflies.
Thanks to tiny new trackers and Bluetooth, scientistsβand youβcan now follow the epic journeys of individual butterflies.
