What is eusociality in ants and bees?

Eusociality is a social system in which individuals in a colony cooperate in raising offspring and divide work into specialized roles. In ants and honeybees, this often means a queen that lays eggs, workers that forage and care for young, and in some species males that mainly mate. Termites also show eusociality, though they are not ants or bees; they are cockroach relatives. This lifestyle allows colonies to function almost like a superorganism, with individuals relying on each other for survival. Eusocial insects are among the most successful animals on Earth because their social organization makes them highly adaptable and efficient.
