The First Bug War, also known as the First Interstellar War, was a conflict fought between the United Citizen Federation, and the Arachnid Species. After several Human-Arachnid conflicts on colony worlds like Port Joe Smith, the war officially began with an Arachnid attack on Buenos Aires and lasted for over 5 years. During the course of the War apart from several meteor attacks on Earth by the Arachnids, it was the Federation which was the aggressor invading deep into the Arachnid Quarantine Zone until Arachnid counter attacks defeated many Federal invasions of their homeworlds.
