This study demonstrates a method to assess visual psychophysics in desert ants by observing changes in their navigational behavior when visual stimuli are altered.

This study demonstrates that nocturnal bull ants use a time-compensated lunar compass to navigate, adjusting their path headings based on predicted lunar azimuthal positions.

This study shows that red honey ants adjust their navigation behavior, increasing oscillations and scanning when familiar visual scenes are altered.

This study investigates how Australian desert ants learn and navigate during colony relocation, finding that relearning walks at both old and new nests are critical for successful relocation and foraging.

This study shows that experienced Melophorus bagoti ants dump waste more efficiently and with spatial fidelity compared to naive ants, suggesting learning improves waste disposal and navigation.

This study examines how bull ants respond to added odours on their foraging route, finding neophobic reactions and altered navigation behaviors.

This study shows that experienced dumpers in Melophorus bagoti ants are better oriented towards their nest than naive ones, indicating improved spatial knowledge from repeated dumping trips.

This study shows nocturnal bull ants use polarized moonlight for navigation during the night, similar to how they use solar polarized light during the day.
