Rare
Under 5% of wildlife watchers report a Bertula retracta sighting in Hong Kong on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 555th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Bertula retracta in Hong Kong on a given day, against under 5% in July to May, the lowest months. That is one of Hong Kong's wettest months, with about 280 mm of rain against 25 mm in December.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Bertula retracta sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Bertula retracta is recorded against all the insects logged in Hong Kong (15 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.
