Rare
Under 5% of wildlife watchers report a Risoba basalis sighting in Singapore on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 960th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report a Risoba basalis in Singapore on a given day, against under 5% in January to November, the lowest months. That is one of Singapore's wettest months, with about 300 mm of rain against 100 mm in February.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Risoba basalis sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Risoba basalis is recorded against all the insects logged in Singapore (5 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.
