With luck
About 10% of wildlife watchers report a Large Brown Cicada sighting in Sapporo on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 44 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July and August
In those months about 20% of wildlife watchers report a Large Brown Cicada in Sapporo on a given day, against under 5% in September to June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Large Brown Cicada is recorded against all the insects logged in Sapporo (8 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.
