On July 23, one of the Japan Meteorological Agency's biological seasonal information, "Tokyo District Minminzemi First Sounding", was reported.
It is said that two days later than normal and three days later than last year.
As the name implies, it is known for its powerful squeal for the size of the body, "Menminminminminminminminminminminminminminmin ...", and it is often heard as "sound effects during the summer."
It is characterized by a series of dark crests on transparent wings, black body color and blue-green patches.
The squealing is exclusively male, but the male and female of the individual can be identified by differences in the structure of the abdomen.
Females have a long and narrow spawning tube at the tip, and males are said to play a role in rhythmic and inflection of squeals.
Even at Tsukuda Park, Minminzemi's "Cicada Toki Rain" tells the summer performance.
When the sound is over, the habit of "squealing and moving" that jumps to other trees (branches) without gaping is also noticeable.
