For spatial orientation, heading information can be processed in two different frames of reference, a self-centered egocentric or a viewpoint allocentric frame of reference. Using the most efficient frame of reference is in particular important if an animal migrates over large distances, as it the case for the monarch butterfly (Danaus plexippus). These butterflies employ a sun compass to travel over more than 4,000 kilometers to their destination in central Mexico. We developed tetrode recordings from the heading-direction network of tethered flying monarch butterflies that were allowed to or
