The poisonous ambush that Sophia had prepared for the mother brains and Insect queens was extremely effective and wiped out almost 70 percent of them. Only a few who had strong poison resistance or had a special type of body were able to survive this ambush. This was definitely a major loss for the Nest of All Chaos danger zone.
The way how the Nest of All Chaos managed to create such a large number of bugs and were able to quickly replenish their forces was through these mother brains and insect queens. In the times of need, these special bugs were able to quickly give birth to a huge amount of offspring who could be used as cannon fodders in the battles.
