  3. Leaf-like lobes on the abdomen and legs

Versus the Toxodera stick mantis: the Toxodera stick mantis lives in Southeast Asia and has a bow-shaped pronotum and leaf-like lobes.

Range

It lives on tall shrubs, bushes, and leafless branches in dry woodland savanna in Africa.

Behavior

At rest it stretches its long front legs out to the sides so it looks like two dry twigs.

When threatened, it rears up, spreads its front legs to show the bright markings inside, and opens its wings to show yellow and black patterns.

Size differs between expert field observations and care sources, so we give a range.
