With luck
About 10% of wildlife watchers report a Dot-Dash Sailer sighting in Osaka on a given day, based on 67 verified sightings from GBIF citizen-science data. It is the 35th most-seen of the 352 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Dot-Dash Sailer is recorded against all the insects logged in Osaka (67 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.
