Abstract:

Division of labour plays a very important role in social insects and could
either be reproductive or non-reproductive in nature. The lack of
morphological differences among individuals in primitively eusocial species
lead to greater flexibility in their social roles making them very
interesting model systems to study division of labour. *Ropalidia
cyathiformis*, a primitively eusocial wasp was chosen as the model system
for the study of reproductive and non-reproductive division of labour. One
of the key findings reveals that while dominance behaviour is used as a
mechanism for reproductive division of labour, age is used for
non-reproductive division of labour. We also compared our findings with
what is already known in a related conspecific, *Ropalidia marginata*. Our
findings showed that *R. cyathiformis* maybe a more primitive species
compared to *R. marginata* and provide a glimpse into the origin of
eusocial insects.
