  • Eusociality (Greek eu: "good" + "social") is a term used for the highest level of social organization in a hierarchical classification. The term "eusocial" was introduced in 1966 by Suzanne Batra1 and given a more definitive meaning by E. O. Wilson.2 It was originally defined to include those organisms (originally, only invertebrates) that had certain features:34

    1. Reproductive division of labor (with or without sterile castes)

    2. Overlapping generations

    3. Cooperative care of young

    The lower levels of social organization, presociality, were classified using different terms, including presocial, subsocial, semisocial, parasocial and quasisocial. ~Wikipedia
