I want to know the answer to the following question:
What type of swarm was a concern because of the emperor's ethics?
All the background I'm provided with is that "If the emperor did not behave according to proper ritual, ethics, and morals, he could disrupt the fine balance of these cosmological cycles and cause calamities such as earthquakes, floods, droughts, epidemics, and swarms of locusts.". Is that enough to answer the question?
Answer: yes
