Every year, billions of Bogong moths (Agrotis infusa) in Australia undertake this annual pilgrimage. Notably, a group of scientists recently discovered that these moths navigate by observing stars. Each spring in Australia, Bogong moths undertake a journey of up to 600 miles. When autumn arrives, Bogong moths return to their breeding grounds to reproduce before ultimately dying. There are still mysteries to unravel, such as which exact stars or constellations Bogong moths rely on or how they compensate for Earth’s rotation during the night.
