Eggs on grape vines?

Eggs on grape vines?

We decided to plant grapes this year, having never done it before. We ended up buying a vine at Lowe's, and we have it under a plant light where it is growing much faster than I expected! But here's the problem, and I'm hoping someone can help me identify it: My husband noticed a couple very small, translucent white balls on the vine when he repotted it. (I need to ask him where he got the soil, now that I think of it.) He removed them with his fingers and we both double checked to make sure there were none left, thinking they are obviously some kind of egg. I went down in the basement today and took a look at the grapevine, only to find that there are more of these eggs! They are maybe a millimeter or so in diameter. They are randomly along the vine and also seem to cluster where the leave clusters protrude from the vine. I've been on google trying to find an answer to what these might be, but I haven't had any luck (it's probably something really obvious.) We are in Northeast Ohio, if that helps. They do look an awful lot like japanese beetle eggs, but everything I've read about them says they lay their eggs in the dirt, not sticking to plants. Anybody have any ideas as to what these could be and how to get rid of them? Thanks!
