One of the big short-horned grasshoppers. Some of these types will swarm, and are generally called locusts. I'm afraid I can't tell you the real name of this one; it might help to know where you are, but then again I'm not a grasshopper pro. "Big" and "little" are about as far as my taxonomy goes there.

it's probably a grasshopper or a Mantis religiosa
