This is a caterpillar of a moth or butterfly. Difficult to say what species based on the images. There are number of very prominent and easily recognizable caterpillars on grapes . This is not one of them. One suggestion from Twitter was Spodoptera, which is a genus of Noctuid moths.
@ZombieAntGuy @plantvillage @plantdisease i would say Spodoptera— Paul R Johnston (@Paul_R_Johnston) July 21, 2014
But it is a caterpillar and it is eating your grapes. You can brush them into a bucket with soapy water and they will die. Dont remove them and throw then away
You can also treat with a Bt spray which is an organic solution that uses proteins of a bacteria that is effective against caterpillars
Do you have many grape vines
