Workers of the ant Myrmica sabuleti mentally add visual cues when they perceive them simultaneously. We previously showed that this requires a maximum horizontal distance of 5 cm and a vertical one of 4 cm between the sighted elements. A critical time limit allowing or not allowing these ants to add up two visual cues could also exist between their successive perceptions. The present experimental work aims to define this temporal limit. Working on four colonies and using two different kinds of graphical elements to be added, we conducted six experiments which showed that M. sabuleti workers still added up elements when the time interval between their successive perceptions equaled 7 minutes or less, but no longer did so when the interval was 8 minutes or more. The critical temporal limit for ants to add up perceived elements thus lies between 7 and 8 minutes.
