Formics, often referred to as Buggers by humans, was the name given to the first alien species that humans encountered. They are most commonly compared to ants, since they have a queen. Whatever the rest of the Formics see, the Queens see. The Formics can not think for themselves, so when their Queen is destroyed, they can not act. They have massive arms and reproduce often. At the end of the book, Ender's Game, Ender Wiggin nearly destroys the whole species unknowingly, but subsequently saves them from extinction by taking the Queen and her egg and trying to find it a new home.
