With luck
About 10% of wildlife watchers report a Sergeant Emperor sighting in Nanjing on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 170th 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 40%, if each day is a fresh chance.
February and December
In those months about 20% of wildlife watchers report a Sergeant Emperor in Nanjing on a given day, against under 5% in January, March–July and September–October, the lowest months. Those are among Nanjing's driest months, with about 55 mm of rain a month against 240 mm in July.
Only Nanjing, in our data
Nanjing is the only city on Wallace's Line with enough records to rate Sergeant Emperor sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sergeant Emperor is recorded against all the insects logged in Nanjing (8 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.
