Which of these is the highest level of insect organization of sociality?

Eusociality is the highest level of organization of sociality. It is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. Eusociality has evolved among the insects, crustaceans, and mammals. It is most widespread in the Hymenoptera (ants, bees, and wasps) and in Blattodea (termites).
