Abstract : Variations of associations between different behavioural patterns were analysed during post-embryonic development in the water stick insect,Ranatra linearis L. (Heteroptera: Nepidae). Behavioural patterns recorded were: quiescence, swimming, crawling, leg waving, body swaying, respiratory ascents breathing, respiratory descents, grooming and feeding activities (predatory attempts, foreleg movements, ingestion). A factorial analysis of correspondance stressed the contrast between the organization of larval behaviour and that of adult behaviour. No behavioural patterns were dropped from the repertoire during post-embryonic development ofRanatra linearis and no new patterns developed in adults outside the reproductive period. Larval behaviour was characterized by more frequent respiratory activities and grooming and adult behaviour was characterized by more frequent locomotory activities. At all larval stages grooming was associated with respiratory activities and crawling, but not with feeding activities.
