With luck
About 10% of wildlife watchers report a Lake Pondskater sighting in Nanjing on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 272 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Lake Pondskater in Nanjing on a given day, against under 5% in April, October and December–February, the lowest months. That is one of Nanjing's wettest months, with about 160 mm of rain against 40 mm in December.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Lake Pondskater sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
24th of 44
Of the 44 cities where we can rate Lake Pondskater sightings, Nanjing ranks 24th at about 10%. The best odds are in Hiroshima (Japan, about 30%), Guiyang (China, about 30%) and Nagoya (Japan, about 20%).
Same order: Hemiptera
The closest relatives of the Lake Pondskater that you can see in Nanjing (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Spotted Lanternfly (about 30%), Yellow-Spotted Stink Bug (about 20%) and Yezoterpnosia obscura (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lake Pondskater is recorded against all the insects logged in Nanjing (13 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.
