Ropalidia are eusocial wasps which make a nest from cellulose mixed with saliva. They also exhibit cooperative brood care differentiation of the colony members. The present studies aim at hypothesising the probable role of temperature in nest building ability of R. marginata. The observations revealed that, raise in temperature was inversely proportional to the number of cells built. The statistical analysis revealed that, there was no significant relationship (p>0.05) between temperature and nest building ability.
