With luck
About 10% of wildlife watchers report a Rothney's Paper Wasp sighting in Hangzhou on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 172 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Rothney's Paper Wasp in Hangzhou on a given day, against under 5% in June, September–October and December–February, the lowest months. That is one of Hangzhou's wettest months, with about 180 mm of rain against 65 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Rothney's Paper Wasp sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
11th of 17
Of the 17 cities where we can rate Rothney's Paper Wasp sightings, Hangzhou ranks 11th at about 10%. The best odds are in Zhengzhou (China, about 20%), Taichung (Taiwan, about 20%) and Wuhan (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Rothney's Paper Wasp is recorded against all the insects logged in Hangzhou (10 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.
