For spatial orientation, animals use a variety of different local (e.g. memorized landmarks) and global cues (e.g. the sun). Especially for long range orientation, global cues such as the solar position and polarized skylight serve as crucial spatial references for many insects. One prominent example is the North American monarch butterfly Danaus plexippus. Each fall, these butterflies start a long journey from North America to their overwintering habitats in Central Mexico. During their migration, they predominantly use celestial cues as spatial references. Currently, I aim to reveal how different orientation cues are processed in the butterfly’s brain. The latter, I investigate with multi-electrode recordings while presenting the animals celestial compass cues.
