    Keep an Eye Out for Tagged Monarch Butterflies

    Late summer marks the beginning of the monarch butterfly’s epic migration to wintering grounds in coastal California and central Mexico. In the western U.S., hundreds of these magnificent orange-and-black butterflies will be sporting white tags — each the width of an M&M and bearing an email address and serial number — in an effort to track the direction, route, and destination of their migratory movements. Researchers are enlisting the help of the public to spot and report these tagged migrants en route to their wintering grounds.
