a trail pheromone (2-Heptanone)

2-Heptanone is a chemical compound known as a trail pheromone used by some insects, like ants, to communicate. When an ant finds food, it releases 2-heptanone along its path, creating a scent trail that other ants can follow to reach the food source. This chemical signal helps coordinate the colony’s efforts in gathering resources efficiently. In essence, 2-heptanone acts as a biological marker, guiding colony members toward important locations and enhancing social cooperation within the insect community.
