With luck
About 10% of wildlife watchers report an Eastern Horse Cicada sighting in Nanjing on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 63rd most-seen of the 272 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.
July and August
In those months about 30% of wildlife watchers report an Eastern Horse Cicada in Nanjing on a given day, against under 5% in January–May and September–November, the lowest months. Those are among Nanjing's wettest months, with about 200 mm of rain a month against 40 mm in December.

Same family: Cicadidae

GBIF citizen-science records
It is estimated from how often the Eastern Horse Cicada is recorded against all the insects logged in Nanjing (20 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.
