Rare
Under 5% of wildlife watchers report a Broad Yellow Oakblue sighting in Singapore on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 735th 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 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Broad Yellow Oakblue in Singapore on a given day, so our monthly data shows no clear season.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Broad Yellow Oakblue sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Arhopala
The closest relatives of the Broad Yellow Oakblue that you can see in Singapore (genus Arhopala, Oakblues) are Dull Oak-Blue (about 10%), Aberrant Oakblue (about 10%) and Major Yellow Oakblue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Broad Yellow Oakblue is recorded against all the insects logged in Singapore (11 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.
