The Markia hystrix is a species of insect that can be found in South America, and is a member of the Tettigoniidae family. Members of this family are often called Katydids.
Like most animals in their family, these strange looking creatures are masters of mimicry. This particular species copies the color and texture of lichens to avoid predators. They are likely aboreal, meaning they live in the trees, and their diet likely consists of plant matter such as leaves and flowers.
