There are portions of my neighborhood right now where you can't hear a person next to you speaking at a normal volume and the foul stench of piles of rotting carcasses is thick. The fact that several million of these things can emerge in unison every 17 years and then warble in perfect unison in a wavelike manner to maximize volume infers an intelligence far superior to our society today as evidenced by the current state of our politics. It's only a matter of time before they take the next evolutionary step and develop the weapons necessary to eliminate us.
