With luck
About 10% of wildlife watchers report a Pied Skimmer sighting in Nanjing on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 272 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.
June and July
In those months about 30% of wildlife watchers report a Pied Skimmer in Nanjing on a given day, against under 5% in September to April, the lowest months. Those are among Nanjing's wettest months, with about 210 mm of rain a month against 40 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Pied Skimmer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
10th of 22
Of the 22 cities where we can rate Pied Skimmer sightings, Nanjing ranks 10th at about 10%. The best odds are in Ningbo (China, about 20%), Daegu (South Korea, about 20%) and Jinan (China, about 20%).
Same family: Libellulidae
The closest relatives of the Pied Skimmer that you can see in Nanjing (family Libellulidae, Skimmers) are Wandering Glider (about 10%), White-Tailed Skimmer (about 10%) and Scarlet Skimmer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pied Skimmer is recorded against all the insects logged in Nanjing (39 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.
