Orthetrum albistylum
In 3 days ~80% in a week >90%
Orthetrum albistylum is a dragonfly species, which occurs from central and south Europe to China and Japan. Its distribution is often patchy but in many areas it is common. The species has recently spread its range northwards to the Baltic Sea coast in Poland. The common name for this species is white-tailed skimmer.
One of the ongoing threats affecting the habitat of Orthetrum albistylum is the production of crops. The water pollution associated with crop production is also having a direct effect on the quality of the habitat of this species. Wikipedia →

Likely
About 40% of wildlife watchers report a White-Tailed Skimmer sighting in Nagoya on a given day, based on 97 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 195 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
August
In that month about 70% of wildlife watchers report a White-Tailed Skimmer in Nagoya on a given day, against under 5% in November to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most White-Tailed Skimmer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 21 cities where we can rate White-Tailed Skimmer sightings, Nagoya has the highest daily chance: about 40%. Next come Daegu (South Korea, about 40%) and Osaka (Japan, about 30%).
GBIF citizen-science records
It is estimated from how often the White-Tailed Skimmer is recorded against all the insects logged in Nagoya (97 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.
