Was out taking care of the grapes and noticed this damage and upon further inspection found these lil tiny Caterpillar looking things that seemed to be the culprit Is this a big worry and if so what are best practices for taking care of them Thank you as always!

Hi- this is the larva of the grape flea beetle. The adults that preceded the larva feed on buds, so are considered a bigger problem than larval feeding on leaves. Typically, no control is recommended for these larvae.
