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.

With luck
About 10% of wildlife watchers report an Indian Palm Bob sighting in Bangkok on a given day, based on 53 verified sightings from GBIF citizen-science data. It is the 47th most-seen of the 245 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.
May to March
In those months about 10% of wildlife watchers report an Indian Palm Bob in Bangkok on a given day, against under 5% in April, the lowest month.
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.
30th of 34
Of the 34 cities where we can rate Indian Palm Bob sightings, Bangkok ranks 30th at about 10%. The best odds are in Mumbai (India, about 30%), Jabalpur (India, about 30%) and Karachi (Pakistan, about 20%).
GBIF citizen-science records
It is estimated from how often the Indian Palm Bob is recorded against all the insects logged in Bangkok (53 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.
