Compared to Stagmomantis limbata, Iris oratoria eats a lesser portion of Orthopteran insects and does not eat as much long bodied insects. S. limbata adults have longer pronota and forelegs than I. oratoria adults. This difference in body size might be an important cause of the dietary differences between the species. Furthermore, the earlier hatch date for S. limbata also might reduce the overlap in Iris oratoria and Stagmomantis limbata diets.
