Leptosia nina, the psyche, is a small butterfly of the family Pieridae (the sulphurs, yellows and whites) and is found in Indian subcontinent, southeast Asia and Australia. The upper forewing has a black spot on a mainly white background. The flight is weak and erratic and the body of the butterfly bobs up and down as it beats its wings. They fly low over the grass and the butterfly rarely leaves the ground level.
From Charles Thomas Bingham's The Fauna of British India, Including Ceylon and Burma. Butterflies. Vol 2.

Forewing: costa speckled obscurely with black; apex black, the inner margin of this inwardly angulate; a very large somewhat pear-shaped post-discal spot also black. Hindwing white, uniform; in most specimens an obscure, extremely slender, terminal black line.
Underside: white; costal margin and apex of forewing broadly, and the whole surface of the hindwing irrorated (speckled) with transverse, very slender, greenish strigae and minute dots; these on the hindwing have... Wikipedia →

Possible
About 20% of wildlife watchers report a Psyche sighting in Surabaya on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 14th most-seen of the 27 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Psyche in Surabaya on a given day, against under 5% in February–March, June–July and September–October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Psyche sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
24th of 38
Of the 38 cities where we can rate Psyche sightings, Surabaya ranks 24th at about 20%. The best odds are in Guwahati (India, about 40%), Yogyakarta (Indonesia, about 40%) and Jamshedpur (India, about 40%).
Same family: Pieridae
The closest relatives of the Psyche that you can see in Surabaya (family Pieridae, Whites, Yellows, and Sulphurs) are Delias periboea (about 20%) and Western Striped Albatross (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Psyche is recorded against all the insects logged in Surabaya (7 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.
