What kind of bugs are these? They are small - 1/2 inch and smaller, and they have infested my driveway. I have a neighbor who shares the driveway, and one of his trees seems to be diseased, so I'm wondering if there is a connection. I've lived in this house for five years, but I've never seen these bugs before. There are hundreds of them. I'm wondering if they are beneficial bugs or bugs that need to be exterminated.
