When I take them out of the water for about half an hour, many cicadas will react. Every day I catch cicadas, I have to soak them in water to soak up the soil, and then wash them casually the next day. Later, they will be found to be moving, which can only be understood as their slow metabolism and extremely low oxygen consumption in water, just like hibernating frogs, you know. There is another kind of cicada, which stays underground for 17 years and won't die like that. This thing is very strange.
