With luck
About 10% of wildlife watchers report a Ōmizuao sighting in Osaka on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 197th 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.
April and June–August
In those months about 10% of wildlife watchers report a Ōmizuao in Osaka on a given day, against under 5% in May and September–March, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Ōmizuao sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 2 cities where we can rate Ōmizuao sightings, Osaka ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Tokyo (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Ōmizuao is recorded against all the insects logged in Osaka (11 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.
