Rare
Under 5% of wildlife watchers report a Green-Suffused Oakblue sighting in Singapore on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 496th 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.
May and June
In those months about 10% of wildlife watchers report a Green-Suffused Oakblue in Singapore on a given day, against under 5% in July to April, the lowest months.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Green-Suffused Oakblue sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Arhopala
The closest relatives of the Green-Suffused 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 Green-Suffused Oakblue is recorded against all the insects logged in Singapore (28 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.
