An insect of the Tettigoniidae family in the Orthoptera order (illustration). One of the insects that sing in autumn, males raise their hind wings slightly at night and make a loud, noisy noise like "gacha gacha" (or "kasha kasha"). The name comes from the fact that the sound sounds like the sound of a horse's bridle. It is commonly known as "gacha gacha." It is distributed from the Kanto region to Kyushu, and lives in tall grasslands near forests. Its body length is around 35 mm. The length to the wing tip is 50 to 70 mm. There are green and brown types of body color, but even the green type has a brownish sound organ. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
