Giant shield mantids of the genus Rhombodera can reach lengths of nearly 12 cms and are more robust than comparably sized mantids of other genera (Tenodera, Macromantis, Hierodula, Idolomantis, Sphodromantis, Deroplatys, Heterochaeta, and Plistospilota) Some larger species have been known to capture and consume frogs, lizards, mice, small birds, and even snakes.
