Thanks mIEKAL for your inquiries which gave me the information to find photos of the specific critters.  Here is a great link http://149.168.1.196/nrid/getDataPub.php?pid=15

Thanks Lon and Robert for your explanations and assurances.  Now I can take pleasure in observing  them.

When these sorts of mites affect grapes, as Dr. Dahl says, they only
cause cosmetic damage and can be ignored.  Usually native predator
mites build up and control them, or if the vines are treated for
powdery mildew, the sulfur used as a mildew control also kills the
mites.

In reference to the thread circulating the last few days, I sent photos
of the red & green spikey growths on the leaves of my beach plums.? (&
from Shirley's description, I believe this is what is on her grapes.)
