Monarchs are one of the most iconic insects in North America — and the only North American butterfly that undertakes a long-distance, multi-generational migration. Unfortunately, this formerly abundant species has experienced dramatic population declines since the 1990s. To better understand and protect these beloved butterflies, biologists are now tracking monarch migration routes with the use of tiny radio transmitters. Join NH Audubon biologist Lindsay Herlihy to explore some of the cutting-edge technologies used to track monarch movements, and to discuss the data NH Audubon biologists are gathering. She’ll also share ways you can help support monarch conservation and research right here in the Granite State.​

Monarchs are the only North American butterfly species that migrates 3,000 miles from Canada and the northern United States to Mexico — and back again — over the course of several generations. Researchers with the Motus Wildlife Tracking Network are now uncovering never-before-seen details of these epic migrations. (photo © Lindsay Herlihy)
