On July 19, when the Kanto region started the rainy season, one of the Japan Meteorological Agency's biological seasonal observation information, "Tokyo District Minzemi First Sound".
It is said that it is two days earlier than normal and three days earlier than last year.
As the name suggests, it is known for the sound of "Meanminminminminminminminminminminminminminminminminminminminmin ..." and is often heard in TV videos etc. as "the sound effect during the summer".
It is one of the representative cicadas that live in Japan.
The wings are transparent, characterized by a series of dark patterns, black body colors and blue-green spots.
Screaming is exclusively male, but the identification point of the male and female of an individual that does not sound is different in the structure of the abdomen.
Females are identified by having protrusions that become spawning tubes at the tip of the abdominal surface, and males are identified by developing abdominal valves.
Even at Tsukuda Park, Minminzemi's "Cicada Rain" tells the midsummer performance.
I am amazed at the size of the squeal for the size of the body.
I hear that the pronunciation membrane of the abdomen is vibrated, amplified in the cavity (resonance room), and loud sounds are made.
The belly valve seems to play a role in adjusting the strength and tone of sound.
Often, once it sounds, it will fly a few seconds later and move to another tree (squealing).
Compared to the sound of a cool and elegant sound of higurashi, the impression of hot bitterness is doubled under the scorching sun, but this is also an environmental sound and feature that can only be tasted in summer.
