Thats a juvenille assassin bug my friend, I'm pretty sure the first picture here is exactly what you have. They eat other bugs, he's probably walking around waiting for food, they don't eat plants so thats good.
Be careful though they will bite people, and the have this really long mouth like a straw that they use to stab their pray(or whatever they bite(more of a stab lol) They DO have some venom that they inject to kill their prey too, its not really dangerous to people, but it'll hurt.
