Creature 148: Parectatosoma hystix

That stick has thorns.
Parectatosoma hystix is a stick insect which has decided that it will not only mimic a stick, but it will mimic a stick you don't want to touch.

If the thorny stick trick doesn't work they have a gland which excretes a liquid irritant to deter predators.  As a last resort the bright red patches under their wings look alarming to some predators and they can move their wings to quickly to make a scary noise.

There males and females vary dramatically in size with males only growing to 6.5 cm long while females can grow to 9.5 cm long. They are sometimes raised by breeders and sold as pets

Parectatosoma hystix is endemic to Madagascar.
