Tiny Translucent Green Grasshopper (with brown stripe)

Check out how long this grasshopper's antenna are!? You know it was picking up the classic rock station all the way in Tennessee. ;) This insect was not too shy mainly because it had found a sunny spot on a log after a night of frost and wasn't giving it up jus' cause I was hovering around in the same sun. I have never seen a hopper like this before, it's green color is very bright and almost translucent in direct light, then it has this awesome opaque brown stripe down it's back with matching eyes!
It's feelers are a good 3-4 times the size of it's body and it was definitely using them readily- swinging them all around while keeping the rest of it's body perfectly still.
Can anyone tell me what the difference between a grasshopper and a cricket is?
