The royal pair at this time cease to be anything but reproductive machines. Queen becomes an egg-laying machine. Male stays around and inseminates her from time to time. Workers and soldiers are both males and females . They hatch out, and are fed as first instars.
Older nymphs do most of the work.
As long as original pair is alive, no other reproductives are present in nest. After queen dies, how long is unknown but could be as long as10-15 years, some workers become fertile and can lay eggs . They are never as fertile as the original queen, and it may take 50-100 of them to maintain the colony . Colony becomes a large underground structure made of a mixture of soil, feces, and saliva. To get to food, workers build runways out of similar material.
