Another name for suspicious song cicadas is common in mountainous areas at low altitudes.

Another name for suspicious song cicadas is very common in low altitude mountainous areas. The sound is very harsh and the frequency is very high, such as electric shocks. There is a significant difference between the voices of the microblog and those of the high altitude areas in front of the microblog. Is it the same cicada? If it’s the same cicada, what’s the reason for the difference in calls? Hope to have a discussion! Thank you@ Entomological small fishMicroblog Video of Relay Microblog
