Rare
Under 5% of wildlife watchers report a Club Silverline sighting in Guangzhou on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 390th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and June
In those months about 10% of wildlife watchers report a Club Silverline in Guangzhou on a given day, against under 5% in May and July–March, the lowest months. Those are among Guangzhou's wettest months, with about 230 mm of rain a month against 30 mm in December.
4th of 6
Of the 6 cities where we can rate Club Silverline sightings, Guangzhou ranks 4th at under 5%. The best odds are in Chattogram (Bangladesh, about 20%), Tuen Mun (China, about 10%) and Taipei (Taiwan, under 5%).
GBIF citizen-science records
It is estimated from how often the Club Silverline is recorded against all the insects logged in Guangzhou (6 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.
