A new study reveals that Bogong moths in Australia navigate their 620-mile migration using both the stars and Earth's magnetic field. Researchers replicated the journey in a lab, finding the moths use the starry night sky as a compass, a first for invertebrates. This dual navigation system provides a backup if one system fails. The discovery highlights the remarkable navigational abilities of these endangered insects, which make this arduous journey only once in their lifetime.
