Walking sticks are long and thin with some species over a foot long. They resemble twigs and can match the green, brown or gray colors of their surroundings.
Science has classified as many as 3,000 separate species of walking sticks. A member of the order known as Orthoptera, which includes bugs like praying mantises, grasshoppers and cockroaches, walking sticks belong to four different families.
Walking sticks live in tropical and temperate climates with many species existing in the United States. Large numbers are in the southern states in habitats that they have specifically adapted to.
The predators of the walking stick are reptiles, birds, bats, spiders and certain primate species. Bats are especially able to locate walking sticks with their echolocation technique, making the insect's camouflage useless.
Walking sticks will stay absolutely still to fool a potential enemy or move back and forth to look like a twig in the breeze. Some will play dead and if need be they can produce a foul substance from their leg joints to discourage pursuit.
