Quasisocial

Quasisocial means co-operative brood care by a single generation of adults in a common nest site, it differs from eusociality by not having reproductive caste differentiation and generational overlap. The term "quasiocial" was introduced in 1966 by Suzanne Batra and given a more definitive meaning by E. O. Wilson. as one of the four categories of insect social behaviour. Quasisocial behaviour is found in the Hymenoptera, spiders and some other invertebrates.
