Tanna japonensis, also called the evening cicada or higurashi (Japanese: 日暮, 蜩, 茅蜩, ひぐらし, ヒグラシ), is a species of cicada, a family of insects, and a member of the genus Tanna. It is distributed throughout East Asia, and is most common in Japan. Its shrill call can be heard most often in the morning and evening.
One of its possible kanji names (茅蜩) is derived from the character (茅) for a category of grasses that includes Miscanthus sinensis, a type of reed that it inhabits. In Japan, it is also known as kanakana (カナカナ) because of the noise that it makes.
The adult male has a body length of 28–38 mm (1.1–1.5 in), the female is 21–25 mm (0.8–1.0 in). The male's abdomen is longer and thicker than that of the female, making it easy to distinguish between them. In addition, the intra-abdominal cavity of the male is more developed, giving it a more resonant call.
The body is coloured reddish-brown with green around the compound eye and in the centre and back of the thorax; mountain dwelling specimens tend to be darker. In Japan, their habitat ranges from temperate Hokkaido in the far north to subtropical Amami Ōshima, close to Taiwan (variants and subspecies... Wikipedia →

Rare
Under 5% of wildlife watchers report an Evening Cicada sighting in Tokyo on a given day, based on 59 verified sightings from GBIF citizen-science data. It is the 220th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report an Evening Cicada in Tokyo on a given day, against under 5% in September to June, the lowest months.
3rd of 3
Of the 3 cities where we can rate Evening Cicada sightings, Tokyo ranks 3rd at under 5%. The best odds are in Sendai (Japan, about 10%) and Osaka (Japan, about 10%).
Same family: Cicadidae
The closest relatives of the Evening Cicada that you can see in Tokyo (family Cicadidae, Typical Cicadas) are Large Brown Cicada (about 30%), Robust Cicada (about 20%) and Kaempfer Cicada (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Evening Cicada is recorded against all the insects logged in Tokyo (59 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
