Read more With Upgraded Transmitters, We Can Now Track Migrating Monarchs Better than Ever | Xerces SocietyA new radiotelemetry transmitter, called the Blu+, is revolutionizing how scientists can track migrating monarchs this fall.
The Blu+ transmitter, developed by Cellular Tracking Technologies and Cape May Point Arts & Science Center (CMPASC), weighs just 0.06g and can be attached to monarch butterflies.
Previous monarch tags could only be detected by specialized receivers. The new Blu+ tags can be detected much more easily, because they are integrated into a network of cellular-connected devices. Now there is potential to get hundreds or even thousands of detections per tag, giving us a much better picture of the route each monarch takes on its journey.
