Arhopala allata
In 3 days ~10% in a week ~20%
Arhopala allata is a butterfly of the family Lycaenidae. It is found in Asia (see subspecies section). A. allata Stgr. is distinguished from anamuta by the much broader black distal margin in both wings of the male and female. The upper surface of the male is deep dark brown with a violet reflection; so dark that the marginal band of 2% mm width only contrasts with the almost black ground-colour in a certain light.Female dark bluish-violet, both wings very broadly margined with black. On the under surface the only essential
difference from anamuta is the much narrower postmedian band of the forewing and the straighter course of it in the hindwing of allata. Wikipedia →

Rare
Under 5% of wildlife watchers report a Rosy Oakblue sighting in Singapore on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 788th 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 Rosy 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 Rosy Oakblue sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Arhopala
The closest relatives of the Rosy 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 Rosy Oakblue is recorded against all the insects logged in Singapore (10 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.
