Rare
Under 5% of wildlife watchers report a Comostola subtiliaria sighting in Osaka on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 246th most-seen of the 352 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July–August and October
In those months about 10% of wildlife watchers report a Comostola subtiliaria in Osaka on a given day, against under 5% in September and November–June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Comostola subtiliaria is recorded against all the insects logged in Osaka (9 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.
