Antennal Circadian Clocks Coordinate Sun Compass Orientation in Migratory Monarch Butterflies
Body clocks in butterfly antennae help guide sun-based navigation during migration

Abstract
Antennae are essential for proper time-compensated Sun compass orientation in migratory monarch butterflies.
- Monarch butterflies possess clocks in their antennae that contribute to navigation.
- The circadian clock previously assumed to be in the brain may actually function in the antennae.
- These findings suggest a new role for antennae in navigation, impacting understanding of orientation in insects.
- The study opens avenues for further exploration of clock-compass connections in other insect species.
