Rare
Under 5% of wildlife watchers report a Bigg's Brownie sighting in Singapore on a given day, based on 43 verified sightings from GBIF citizen-science data. It is the 411th most-seen of the 1045 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.
February and May
In those months about 10% of wildlife watchers report a Bigg's Brownie in Singapore on a given day, against under 5% in March–April and June–January, the lowest months.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Bigg's Brownie sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Bigg's Brownie is recorded against all the insects logged in Singapore (43 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.
