pheromone trails

Pheromone trails are chemical signals that social insects like ants leave on the ground to communicate with each other. When an ant finds a food source, it deposits these chemicals along the path back to the colony. Other ants detect the scent, follow the trail, and reinforce it if they find food, creating an efficient route. This collective behavior helps the colony find and gather resources effectively. Pheromone trails are a simple yet powerful form of communication that optimize foraging and navigation among social insects.
