Orthetrum albistylum
In 3 days ~30% in a week ~50%
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 →

With luck
About 10% of wildlife watchers report a White-Tailed Skimmer sighting in Suzhou on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 55th most-seen of the 65 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June and July
In those months about 20% of wildlife watchers report a White-Tailed Skimmer in Suzhou on a given day, against under 5% in August to March, the lowest months. Those are among Suzhou's wettest months, with about 180 mm of rain a month against 45 mm in December.
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.
18th of 21
Of the 21 cities where we can rate White-Tailed Skimmer sightings, Suzhou ranks 18th at about 10%. The best odds are in Nagoya (Japan, about 40%), 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 Suzhou (5 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.
