Quasisocial means co-operative brood care by a single generation of adults in a common nest site[1], it differs from eusociality by not having reproductive caste differentiation and generational overlap[2]. The term "quasiocial" was introduced in 1966 by Suzanne Batra[3] and given a more definitive meaning by E. O. Wilson.[4] as one of the four categories of insect social behaviour. Quasisocial behaviour is found in the Hymenoptera, spiders[5] and some other invertebrates.
