For the first time, scientists are able to track the migration of monarch butterflies across much of North America in real time, actively monitoring individual insects on their journeys–all the way from Canada to their overwintering colonies in central Mexico.
Now, researchers are learning that the monarch migration is even more epic than previously thought. Even when blown off course, monarchs have been observed using their strong wing muscles and navigational abilities to get back on track for their destination.
“We can already see that a lot of things we thought we knew about how these insects move are oversimplifications,” said Dr. Chip Taylor, founder of Monarch Watch.
Cellular Tracking Technologies of New Jersey built the tiny solar-powered radio tagtrackers, relying on the expertise of staff members with roots in conservation biology. (The company also makes tracking devices suitable for other animals ranging from bumblebees to elephant seals.) The butterfly tag (called BlūMorpho) is modified in a way that allows its signals to be automatically detected by billions of Bluetooth-enabled devices within a range of about 300 feet.
While the technology produces amazing data, it’s not expected to supersede traditional tagging efforts any time soon, as each sticker comes with a price tag of $200 each, and requires some expertise to affix. But as researchers continue to gather data–who knows what might be next?You’ll find images of the new tags on the company’s website, https://celltracktech.com/pages/project-monarch-collaboration-2025 For more information on monarch tagging, visit monarchwatch.org
