New discovery sheds light on monarch migration: 10-01-2008
Scientists believe they have found new information to explain how monarch butterflies are able to navigate their way from Canada to Mexico so they can nest for the winter.
Steven Reppert, a neurobiologist from the University of Massachusetts, found that the butterflies have circadian clocks that enable them to use the sun as a compass.
According to National Geographic, the researchers found proteins in the butterflies that are also found in animals and they believe these proteins let the butterflies navigate using the sun.
"A butterfly's brain is no bigger than the head of a pin, and yet it has this incredible capability. So we really want to understand that," he said.
Lincoln Brower, a monarch expert at the University of Florida, said the study indicated the crucial information that could be gained from studying the butterfly.
The monarchs migrate south when the first frost arrives and head north when it is spring.
