First GPS-Tracked Monarchs Reach Michoacán Winter Sanctuary

First GPS-tracked monarchs reach Michoacán winter sanctuary

The first monarch butterflies tracked with solar-powered location tags have arrived in the oyamel fir forests of Michoacán, marking a scientific milestone for the conservation and study of their migration. These early-arriving butterflies were released in late September in Lawrence, Kansas, in the United States, and traveled a migratory journey of more than 4,000 kilometers in 43 days.   During this time, they crossed Kansas, Oklahoma and Texas …

With Upgraded Transmitters, We Can Now Track Migrating Monarchs Better Than Ever

Xerces Society reported A 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 easil…
