The way ants process newly found food varies depending on the species, colony size, food size, and individual colony. Some ants consume the food on the spot and transport it in their social stomachs back to the nest to feed other colony members. Others bury the food to hide it from thieves and work on it further in peace. Some ants cooperatively carry the food, and others may employ different strategies altogether.
Here are 2 primary ways ants respond when they first discover a new source of food:
Pheromonal Trailing - The Ant Mapping System
When an ant discovers a new source of food containing protein, carbohydrates, and water, it releases a trail of pheromones to alert other ants to the food's location. Other ants follow the trail to collect and transport the food back to the colony. They share the food with other colony members, including the queen and larvae. The protein nourishes the larvae, while the carbohydrates provide energy for adult ants. Over time, the colony establishes a more permanent trail to the food source, making it easier and more efficient to collect and transport food.
Trophallaxis - The Internal Ant Lunch Box
Trophallaxis refers to the process of food sharing among ants. One ant regurgitates a small amount of liquid food from its social stomach, which is then consumed by another ant. This food-sharing behavior allows all members of the colony to access the nutrients they need to survive and thrive, even if some ants are unable to locate or collect food on their own. Trophallaxis also helps to communicate about food quality and availability and exchange beneficial gut microbes, which help to maintain the health and well-being of the entire colony.
In summary, discovering a new food source is crucial for an ant colony's survival and well-being. Ants use complex social and communication behaviors to ensure the efficient and effective acquisition of resources.
