It is famous for its exceptional mimicry, possessing a flattened, leaf-like thorax and intricate wing patterns that make it nearly indistinguishable from a dried leaf when stationery.

Humidity: Requires high humidity levels of 60%–80% to ensure successful moulting.
Housing: Needs a vertical enclosure at least three times as tall as the mantis's length to allow for molting.
