Where are a cicada's ears located on its body?

The cicada is a common insect in our country, relatively common in temperate and tropical regions. When young, it lives parasitically in the soil; after growing up, it climbs onto trees to feed on plant roots, sap and so on, so for farmers it is a pest. So where are a cicada's ears located?

1. Where are a cicada's ears located?

A cicada's ears are located near the second segment of its abdomen. They are composed of a relatively thick tympanic membrane and 1500 scolopidial sensilla beneath it. Generally, when there is sound outside, the sound waves are transmitted to the auditory organ, then sent to the brain, and finally the sound is heard. Because the sound waves it can perceive are limited, a cicada's hearing is very poor.

2. How long is a cicada's lifespan?

There are many species of cicadas, and different species have different life cycles. The life cycle of French cicadas is mostly 4 years, while in North America there are cicadas with a lifespan of as long as 17 years. The lifespan of Chinese cicadas is mostly 3 to 7 years, of which nearly half are 5 years, and a few can live through 8 to 9 years.

Overall, a cicada's ears are located near the second segment of its abdomen, and because the sound waves it can perceive are limited, its hearing is very poor.
