That's what I call these little beetle like bugs. They are the neatest bug around where I live. They are usually brown, and if they get turned on there back they will pop their back. It sound like a click, but when they do this thrust, or as I like to say a "crunch," it flings it's self into the air and usually lands on its feet. I don't cause harm to them, but i like to hold there abdomen and entertain myself with their clicking. Lol Do you guys know what I am talking about. I'll get a pic for ya.
