So coming out at night can reduce death, and cicadas can be caught around 8 pm in summer. Cicadas are usually on the branches at this time, so it is easy to catch them.
Cicada will hide in the ground during the day. If it crawls out of the amoeba in rainy days, its hole will be washed away by the rain, which is not conducive to concealment during the day.
So cicada monkeys don't come out in rainy days, but if the rain stops at night, the peak time for cicada monkeys to come out is about half an hour after the rain, and you can also choose to catch them at this time. ?
This male cicada can sing. Its vocal organ is located in the abdominal muscles, and it is covered with an eardrum like a drum. The eardrum vibrates and makes a sound. Because the vocal cord muscles can expand and contract about 65,438+0,000 times per second, and the cover plate and tympanic membrane are empty, which can play a role of * * *, so its singing is particularly loud.
