In 3 days ~30% in a week ~60%
Chremistica ochracea (Walker, 1850) is a species of cicada in the suborder Auchenorrhyncha, which includes cicadas, leafhoppers, planthoppers, treehoppers, froghoppers and spittlebugs. They are usually referred to as 'thin winged cicada' in Taiwan and 'peaceful cicada' in China due to their abundance in these areas. They can be identified by their green appearance with thin, greenish, transparent wings and are heavily distributed in China, Taiwan, Japan, India and Malaya. However, there are limited number of scientific papers that describe the characteristics and behaviour of this species in detail.
They are also used to be known as Rihana ochracea which was introduced by Distant (1904), claiming Rihana as a new genus. Genus Rihana however, was also known as a subgenus of Cicada Linnaeus and to some species from Cicada Stål, Chremistica Stål and Diceroprocta Stål.
Based on diagnosis on all Chremistica species erected by Stål in 1870, their eyes are small or medium-sized, very prominent laterally and set widely apart on their triangular head with the piece of frontoclypeus anteriorly prominent. Its tymbal is completely covered with tymbal covering. By looking at... Wikipedia →

With luck
About 10% of wildlife watchers report a Peaceful Cicada sighting in Taichung on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 55th most-seen of the 197 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Peaceful Cicada in Taichung on a given day, against under 5% in April and August–February, the lowest months. That is one of Taichung's wettest months, with about 310 mm of rain against 40 mm in December.
Among the best
Of the 6 cities where we can rate Peaceful Cicada sightings, Taichung ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Taipei (Taiwan, about 10%).
Same family: Cicadidae
The closest relatives of the Peaceful Cicada that you can see in Taichung (family Cicadidae, Typical Cicadas) are Cryptotympana takasagona (about 20%), Eastern Horse Cicada (about 10%) and Black And Scarlet Cicada (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Peaceful Cicada is recorded against all the insects logged in Taichung (21 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.
