nest-mate recognition

Nest-mate recognition is the ability of animals, particularly social insects like ants and bees, to identify and differentiate their own colony or nest mates from outsiders. This recognition is crucial for maintaining colony cohesion and preventing invasion by intruders. It relies on chemical cues, such as pheromones, which are unique to each colony. When an individual encounters another insect, it assesses these chemical signals to determine whether it is a friend or foe. This behavior helps protect the nest, ensuring resources and safety remain within the group.
