The monarch butterfly, a captivating symbol of nature’s beauty, has become the subject of new tracking technology that aims to closely monitor its impressive migration patterns across North America. Project Monarch, a collaboration involving multiple organisations, has developed small solar transmitters that can be secured onto these butterflies, allowing them to be detected via Bluetooth. This innovative approach not only facilitates scientific research but also invites the public to participate in tracking the journey of these remarkable insects.

On 14 September, Canadian nonprofit Nature NB made an exciting announcement via Facebook, urging people to activate Bluetooth on their smartphones. The butterflies equipped with new BluMorpho+ tags, tagged in New Brunswick, are poised to begin their migration to Mexico for the winter. Nature NB proudly stated that they are pioneering this technology within the province.
The BluMorpho tags, which weigh only 0.066 grams, are affixed to the butterflies’ thorax with eyelash glue. These devices operate through passive Bluetooth technology, allowing anyone with an enabled Bluetooth device to log data when they come within approximately 328 feet of a tagged butterfly. This method replaces the previous system of numbered wing tags, which relied on chance sightings and reports from observers.
Jim Wilson, a naturalist affiliated with the Point Lepreau Bird Observatory—collaborators on the project—expressed optimism about the potential of this new technology. He explained that the traditional method limited researchers’ ability to track butterflies accurately. “This is now online; you can go on there and find out where that monarch is,” he noted, highlighting the enhanced data collection that this new approach offers.
Early results from the transmitters have already revealed crucial stopover points during the butterflies’ migration through New Brunswick. Other regions are also embracing this tracking initiative; notably, in Oregon, 15 monarch butterflies were tagged and released in early September, with a total of 200 expected to be deployed across Oregon and Idaho in the coming weeks.
David James, an associate professor of entomology at the University of Washington, noted significant discoveries from their observations. For instance, one tagged butterfly flew from Oregon to California in just ten days, while another covered 125 miles in four days. “We’re collecting a lot of data that we didn’t know about the movement of these butterflies,” he reported, illustrating the groundbreaking advancements this project represents in entomological research.
This tracking initiative provides more than mere data; it holds implications for conservation strategies. Emma Pelton, a senior conservation biologist for the Xerces Society, stated that understanding migration patterns may help identify critical habitats crucial for the butterflies’ survival. She highlighted that the migration route may bring attention to the effects of pesticides and the availability of nectar sources along their journey.
Involving the public through the tracking app promotes greater awareness and appreciation for monarch butterflies, an animal often regarded with affection. Pelton added, “I do think of the power of storytelling and connection, and monarchs tend to be an animal people are naturally drawn to.” She believes that these individual stories of the butterflies’ experiences, including the challenges they face during migration, could inspire further interest in conservation efforts.
As millions of monarchs begin their annual migration, the excitement surrounding this tracking technology comes at a pivotal time. The Farmers’ Almanac notes that some butterflies leave southern Canada and the northern U.S. as early as August, with the main migration waves occurring throughout September and October. Remarkably, these butterflies may travel as far as 3,000 miles to reach the mountains of central Mexico, while others from the western population navigate a different route towards northern Baja California.
Project Monarch’s advancements promise to enhance our understanding of the migration patterns and behaviours of these iconic butterflies. The use of technology in wildlife research could change not only how we study these delightful insects but also how we advocate for their preservation in an ever-changing environment. With public engagement and scientific research working hand-in-hand, the future looks hopeful for both monarch butterflies and the efforts dedicated to their conservation.
