pheromone trail
Chemical breadcrumb route
A pheromone trail is a chemical pathway laid down by insects, especially ants, to guide others of their species to food sources or back to the nest.
The scent strengthens as more individuals follow the route, creating self-reinforcing pathways: The ants quickly formed a pheromone trail to the spilled sugar.
The concept extends figuratively to any accumulating signal that draws followers along the same path.
