This is a Thread Legged Bug, an Assassin Bug in the subfamily Emesinae, and it is a beneficial predator. It actually does have six legs if you look closely. Four rear legs are used for walking, and projecting out in front of the two antennae are the pair of raptorial front legs that are used to capture prey. Here is a BugGuide image for comparison.
