Can You Identify This Pest On Our Grape Leaves?

Hi- We have what was a very healthy grape vine growing in our bay side garden in southern Delaware. Just recently, we noticed these “things” on the underside of some grape leaves. Do you know what these are and how to get rid of them? Thanks

It could be black Grape Phylloxera, or root aphids, which are not aphids but look similar. You can tell if they are flea beetles, because they will look metallic bluish black. The lighter round things could be galls or scale. These articles should help pinpoint the bugs, but Neem oil should take care of any of them.
