I think I have cucumber beetles but I am not sure. They look like the pictures I have seen. One day nothing, then next day probably 40 but only on the broccoli. The broc never made heads or anything but I just left it there. I have cucs, pumpkins, cantaloupe, honeydew, watermelon, corn, beans, eggplant, peas, but no beetles on any of those. I pulled out the broc today and killed all the beetles I could see. They were slow movers, they did not fly. Is that normal? I assumed they would fly. Is there anything else it could have been? Any ideas why on the broccoli and nothing else? I am going to keep watching and hand pick like I have been doing with squash bugs and eggs. I also read about Kaolin clay which I think I will try.
