Hello everyone! I am really hoping to get some help because I don\'t know where to even start! Haha. I started a vegetable garden and was excited because I started getting flowers on my zucchini and spaghetti squash but now, this happened! (Pictures below) and I have seen other plants like my tomatoes having something eating the leaves. I think I found the culprit (the picture of the little black dots) but I have no idea what it is. Please help!
