Alien (The Screwfly Solution)

This is an unnamed species of beings which look vaguely like angels, spirits or fairies. They have engaged in a successful or nearly successful attempt to exterminate the Human species on Earth, doing so by creating an airborne agent that stimulated the minds of male Humans and caused them to become homicidally aggressive towards the females. Whether they ultimately succeeded in conquering Earth is never revealed, but it is presumed that they did.
