With luck
About 10% of wildlife watchers report a Shadow-Winged Resin Bee sighting in Hong Kong on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 330th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May to October
In those months about 10% of wildlife watchers report a Shadow-Winged Resin Bee in Hong Kong on a given day, against under 5% in November to April, the lowest months. Those are among Hong Kong's wettest months, with about 180 mm of rain a month against 25 mm in December.
Among the best
Of the 4 cities where we can rate Shadow-Winged Resin Bee sightings, Hong Kong ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Shadow-Winged Resin Bee is recorded against all the insects logged in Hong Kong (31 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.
