Ropalidia marginata (Lep.) (Hymenoptera: Vespidae) is a primitively eusocial wasp which lacks morphological caste differentiation. By constructing time activity budgets for individually identified wasps and subjecting these to multivariate statistical analysis, we have shown that adult female wasps can be classified into one of the three behavioural castes namely Sitters, Fighters and Foragers. In recent times we have often found it necessary to use laboratory colonies for a variety of experiments. It is important therefore to see if social organisation of the laboratory colonies is similar to that in natural colonies. This report describes the results of 306 hrs of observations of 2 laboratory colonies that were established by marking and releasing all adults present on two natural colonies.
