Finn Lewis didn't know, but Keller could tell Finn that when the Insect Swarm started going mad, within a month's time, even though there was still a long way to go before the Insect Swarm could evolve a Leviathan, it was no problem at all to breed a huge army of corrupted flying insects capable of traveling across planetary systems and attacking other planets within the same system!

And these spreading bases, as long as they had started hatching for more than ten days, almost all had a Queen commanding the battles. And in those target planets, the Queens had long since infiltrated.
