But computer scientists can overcome this problem in an artificial system by introducing pheromone decay: when the chemical evaporates quickly, longer paths will have trouble maintaining stable pheromone trails.

This visualization is based on the foraging behavior of the seed harvesting ant P. barbatus, a species which does not use pheromone trails for finding food.

Moths follow pheromone trails and also use the moon for guidance.

Bruckstein's model replaces the pheromones by dynamical rules, but this does not deny the importance of pheromones in practice: the rules are a simplified version of «follow the previous pheromone trail but smooth it out a bit».

The scientists had already verified in previous studies that the «persistence» of ants, or rather, their tendency not to change their direction while there are no obstacles or external effects, together with the «reinforcement» occurring in areas which they have already visited (thanks to the pheromone trail that they leave) are two factors which determine their routes as they forage.

Researchers working on the Ribeirão Preto campus of the University of São Paulo (USP) in Brazil have discovered that a bacterium found in the microbiota associated with leafcutter ant species Atta sexdens rubropilosa produces the so - called «trail pheromones,» i.e, the aromatic chemical compounds used by the ants to lay a trail to their nest.

If it finds food it will follow the trail back to the nest and leave more pheromones, creating a stronger trail which the other ants in the colony will follow.
