Hyalessa maculaticollis
In 3 days ~60% in a week ~90%
Hyalessa maculaticollis is a species of cicada found in Northeast Asia in the order Hemiptera. Regarding the classification, the genus of the species was changed from Hyalessa to Oncotympana because of its difference from the species found in the Philippines.
In Japan, the name of this cicada is derived from the sound it makes. It is known as minminzemi (ミンミンゼミ, literally, minmin cicada) because of its well-known male song that sounds like 'mi—n, minminminminmi...' (Japanese: ミーンミンミンミンミンミー...).
In Korea, it has the name chammaemi (참매미) (literally 'true cicada' or 'common cicada'), indicating the commonality of this species in Korea. In China, it is called diāo liáo (蛁蟟). Hyalessa maculaticollis is found in China, Japan, the Korean Peninsula and maritime areas of Russia. Individuals in Korea, Eastern China and Far East Russia were considered to be Hyalessa fuscata (Distant, 1905) but recent taxonomic data shows H. fuscata is a synonym of H. maculaticollis.
In Japan, they are distributed from the Oshima Peninsula in southern Hokkaido to Honshu, Kyushu, and their surrounding islands (Tsushima, Koshiki Islands). Their distribution is limited by the... Wikipedia →

Possible
About 30% of wildlife watchers report a Robust Cicada sighting in Seoul on a given day, based on 367 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 525 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
July and August
In those months about 50% of wildlife watchers report a Robust Cicada in Seoul on a given day, against under 5% in April–June and October–February, the lowest months. Those are among Seoul's wettest months, with about 310 mm of rain a month against 20 mm in January.
Among the best
Of the 8 cities where we can rate Robust Cicada sightings, Seoul ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Daegu (South Korea, about 30%).
Same family: Cicadidae
The closest relatives of the Robust Cicada that you can see in Seoul (family Cicadidae, Typical Cicadas) are Eastern Horse Cicada (about 20%), Large Brown Cicada (about 10%) and Kaempfer Cicada (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Robust Cicada is recorded against all the insects logged in Seoul (367 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.
