I have lost the thread that mentioned flea beetles. I have been assuming the little bitty holes in radishes, tomatoes and especially the ground cherry were from flea beetles. But I never see anything like that on the plants. Do they do their damage at night? Should I worry about it? I was starting to wonder if it was a disease instead of bug damage. Doesn't seem to be bothering the ground cherry, but they look like they've been hit with buckshot!
