Forewing with ochreous-white spots, a small one in the middle of the discocellulars, sometimes a minute one above it, three sub-apical small spots, the upper one usually minute, three discal larger spots in an oblique line, the upper one before the middle of the first median interspace, the second (somewhat oval) before the middle of the first median interspace, the third (a long oval) a little beyond the middle of the interno-median interspace; these discal spots varying much in size. Hindwing paler than the forewing, with a broad dark costal margin, lint without any markings. Cilia of both wings brownish-ochreous. Underside grey tinged with pinkish. Forewing with the inner portion below the subcostal vein suffused with black, leaving the apex broadly pinkish-grey, the spots as on the upperside.

Possible
About 20% of wildlife watchers report an Indian Palm Bob 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.
May and July
In those months about 30% of wildlife watchers report an Indian Palm Bob in Surabaya on a given day, against under 5% in January–April and September, the lowest months. Those are among Surabaya's driest months, with about 80 mm of rain a month against 330 mm in January.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Indian Palm Bob sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 34
Of the 34 cities where we can rate Indian Palm Bob sightings, Surabaya ranks 9th at about 20%. The best odds are in Mumbai (India, about 30%), Jabalpur (India, about 30%) and Karachi (Pakistan, about 20%).
Same order: Lepidoptera
The closest relatives of the Indian Palm Bob that you can see in Surabaya (order Lepidoptera, Butterflies and Moths) are Great Eggfly (about 30%), Lime Swallowtail (about 20%) and Blue Pansy (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Indian Palm Bob 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.
