The Horse-headed Grasshopper, also called Horsehead and Jumping Stick Grasshopper,
looks more like a stick insect than a grasshopper. It is native to Peru.
The female is woody brown and some 14-15cm long, much larger than the male which is green and
8-9cm long. They look like twigs when several are together.
They don't fly but can jump.
Pseudoproscopia scabra from northeastern South America looks similar and is also called the Horse-headed Grasshopper.
