This is called as Cicada. In Chinese called 蟬"Chan". Once if you see this kind of insect that's mean it telling us The Summer is Coming! So coming this day sure gonna be the Hot Hot Day! This few day no wonder I always see the sky blue blue one not even a small cloud up in the sky!
But do you know this Cicada they only live for 2 weeks nya.... But before they turn into the Cicada they are living under the ground up to 7 years. Then after 7 years in the ground baru they come out live for 2 weeks.
