With luck
About 10% of wildlife watchers report an Aberrant Oakblue sighting in Singapore on a given day, based on 229 verified sightings from GBIF citizen-science data. It is the 140th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
Any time of year
In every month with enough records, about 10% of wildlife watchers report an Aberrant Oakblue in Singapore on a given day, so our monthly data shows no clear season.
Yes
Of the 2 cities where we can rate Aberrant Oakblue sightings, Singapore has the highest daily chance: about 10%. Next come Kuala Lumpur (Malaysia, about 10%).
Same genus: Arhopala
The closest relatives of the Aberrant Oakblue that you can see in Singapore (genus Arhopala, Oakblues) are Dull Oak-Blue (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 Aberrant Oakblue is recorded against all the insects logged in Singapore (229 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.
