With luck
About 10% of wildlife watchers report an Oraesia emarginata sighting in Nagoya on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 116th most-seen of the 195 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.
October
In that month about 30% of wildlife watchers report an Oraesia emarginata in Nagoya on a given day, against under 5% in May–July and November–March, the lowest months.

GBIF citizen-science records
It is estimated from how often the Oraesia emarginata is recorded against all the insects logged in Nagoya (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.
