What Is It? Friend or Foe...?

... Hubsy is concerned. I think it's a FireBug. i wiki'd it. No, it doesn't frequent The Moon! That's our driveway! My neighbor was concerned it was "an asian beetle" and yes, it is. It aggregates (lots of individuals on one plant) and I have a photo of that to come. Another thing that's striking, in a Halloween-y way. So far, I have not read that it is harmful. ??
