| contents | Bogong moths use a stellar compass for long-distance navigation at night. Dreyer, David Adden, Andrea Chen, Hui Frost, Barrie Mouritsen, Henrik Xu, Jingjing Green, Ken Whitehouse, Mary Chahl, Javaan Wallace, Jesse Hu, Gao Foster, James Heinze, Stanley Warrant, Eric Animals Moths Animal Migration Seasons Spatial Navigation Magnetic Fields Flight, Animal Australia Cues Male Female Darkness Each spring, billions of Bogong moths escape hot conditions across southeast Australia by migrating up to 1,000 km to a place that they have never previously visited-a limited number of cool caves in the Australian Alps, historically used for aestivating over summer. At the beginning of autumn, the same individuals make a return migration to their breeding grounds to reproduce and die. Here we show that Bogong moths use the starry night sky as a compass to distinguish between specific geographical directions, thereby navigating in their inherited migratory direction towards their distant goal. By tethering spring and autumn migratory moths in a flight simulator, we found that, under naturalistic moonless night skies and in a nulled geomagnetic field (disabling the moth's known magnetic sense), moths flew in their seasonally appropriate migratory directions. Visual interneurons in different regions of the moth's brain responded specifically to rotations of the night sky and were tuned to a common sky orientation, firing maximally when the moth was headed southwards. Our results suggest that Bogong moths use stellar cues and the Earth's magnetic field to create a robust compass system for long-distance nocturnal navigation towards a specific destination. |
