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 Taipei on a given day, based on 193 verified sightings from GBIF citizen-science data. It is the 56th most-seen of the 765 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 and July
In those months about 30% of wildlife watchers report a Peaceful Cicada in Taipei on a given day, against under 5% in November to April, the lowest months.
Yes
Of the 6 cities where we can rate Peaceful Cicada sightings, Taipei has the highest daily chance: about 10%. Next come Taichung (Taiwan, about 10%) and Kaohsiung (Taiwan, about 10%).
Same family: Cicadidae
The closest relatives of the Peaceful Cicada that you can see in Taipei (family Cicadidae, Typical Cicadas) are Cryptotympana takasagona (about 20%), Eastern Horse Cicada (about 10%) and Grass 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 Taipei (193 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.
