Watch how antlions build traps and capture ants

I've come across antlion traps in Colorado. It's incredible to see the little legs of an antlion poking out from the bottom of a small pit, flicking dirt at any ants that come near, causing them to tumble down to the inclined sides of the pit into the jaws of the antlion. If you haven't seen an antlion trap in person, this BBC Earth video is the next best thing.
