The most distinctive feature of Deroplatys desiccata is its extraordinary leaf-like appearance. The mantis has a flattened and elongated body, with intricate patterns and coloration resembling a dried leaf. This effective camouflage helps it remain inconspicuous in its natural habitat, often among dead leaves on the forest floor.
Adult Deroplatys desiccata individuals are relatively large compared to other mantis species, with females typically reaching lengths of around 3 to 4 inches (7.5 to 10 cm). Males are usually slightly smaller. The lifespan of Deroplatys desiccata is relatively short, typically ranging from a few months to a year, depending on factors such as gender and environmental conditions.
