A Robust Cicada

Hyalessa maculaticollis belongs to the Insecta class Hemiptera Cicidae.

Distributed in the Korean Peninsula, China, Russia's Maritime Province, and Japan. The body length is approximately 35 mm and the length including wings is approximately 58 mm. The borders and patterns on the head and chest of most common cicadas are usually green, but in the case of the West Island, many individuals are yellow or orange. Black cicadas appear from July to September, and their population is highest during midsummer, from late July to August. It cries 'Meem Meem' or 'Meem Meem', which is the cicada's cry that most people know. Once the male cries, he leaves the location and moves to another tree. It is very common regardless of whether it is a city or a rural area, and is most common in forests around the foot of mountains or valleys.

crying sound
The cicada makes a series of sounds such as 'meemmem' or 'mimmim' and then makes a high-pitched 'mim' sound at the end. After crying once, it moves to another tree. The Japanese cicada cries 'Mim-mim-mim-mim' and sometimes continues the 'mim-mim-mim-mim' part.
