Ghost Mantis
Phyllocrania paradoxa · also called ghost mantises
Among a scatter of dried, curling leaves on the forest floor, a ghost mantis sits motionless, its own body flattened and irregular enough to pass as just another piece of dead foliage. An unsuspecting fly wanders close, and the leaf that wasn’t a leaf strikes without warning.
Overview
The ghost mantis, Phyllocrania paradoxa, is a leaf-mimicking predatory insect native to forest habitat across East Africa and Madagascar. Its irregular, leaf-shaped body flaps and gentle wind-mimicking sway make it one of the more convincingly disguised ambush predators among mantis species.
Camouflage down to the movement
Beyond simply resembling a dead leaf in shape and colour, the ghost mantis extends its disguise into motion itself, swaying like foliage in a breeze rather than moving with the deliberate motion that might otherwise give away a hidden predator.

Ghost Mantis: common questions
Why is the ghost mantis shaped so strangely?
A ghost mantis has irregular, flattened, leaf-like flaps extending from its head, thorax, and legs, an appearance that closely resembles a dried, curling dead leaf rather than a typical insect body shape, an effective camouflage adaptation that helps it avoid predators and ambush prey among leaf litter.
Why does the ghost mantis sway back and forth?
When it does move, a ghost mantis often sways gently from side to side, a motion that mimics the natural swaying of a leaf or twig in a light breeze rather than the more obviously deliberate movement of an actively hunting insect, helping maintain its disguise even while relocating.
Are all ghost mantises the same colour?
No, a ghost mantis can occur in either a brown or green colour form, with the specific colouration an individual develops often influenced by environmental conditions and the colour of its surroundings during development, allowing different individuals to blend into slightly different leaf-litter environments.
Where does the ghost mantis live?
The ghost mantis is native to forest habitat across parts of East Africa and Madagascar, generally found among dead leaves and dried vegetation, where its irregular, leaf-like body shape and colouration provide the most effective camouflage from both predators and prey.
