Phyllocrania paradoxa, common name ghost mantis, is a small species of mantis from Africa remarkable for its leaf-like body. It is one of the three species in the genus Phyllocrania.
Compared to many other praying mantises, the ghost mantis is a “miniature species” growing to only about 45 to 50 millimetres (1.8 to 2.0 in) long.
It comes in various brownish shades from very dark brown (almost black) to greenish gray. An individual’s colors change between molts and are also dependent on light and humidity levels. source
