In 3 days ~30% in a week ~60%
Deudorix epijarbas, the cornelian or hairy line blue, is a species of lycaenid or blue butterfly found in south and southeast Asia from India to Fiji, including the Philippines, and also the tropical coast of Queensland in Australia. The species was first described by Frederic Moore in 1857.
Male. Upperside scarlet-red. Forewing with broad black costal and outer marginal borders, the costal band has its inner margin somewhat curved, being limited by the median vein, consequently it is broadest at the apex, its inner edge on the outer margin is uneven, and at the hinder angle the black band is continued for a short distance along the hinder margin; the rest of the hinder margin is narrowly suffused with black, and so is the sub-median vein. Hindwing with the costa, base and abdominal area suffused with lilackish, the abdominal fold brown, outer marginal line finely black, anal lobe black with a small red mark in it; tail black, tipped with white, the veins often more or less finely black. Antennae black, ringed with white, club with a red tip and with a white streak on the underside below it. Underside greyish-brown, markings indicated by their white edges. Forewing... Wikipedia →

With luck
About 10% of wildlife watchers report a Cornelian sighting in Singapore on a given day, based on 600 verified sightings from GBIF citizen-science data. It is the 82nd most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
December and January
In those months about 20% of wildlife watchers report a Cornelian in Singapore on a given day, against about 10% in February to November, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Cornelian sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 8 cities where we can rate Cornelian sightings, Singapore has the highest daily chance: about 10%. Next come Salem (India, about 10%) and Taipei (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Cornelian is recorded against all the insects logged in Singapore (600 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.
