Orgyia postica, the cocoa tussock moth or hevea tussock moth, is a species of moth of the subfamily Lymantriinae of the family Erebidae found in the Oriental tropics of India, Sri Lanka, Myanmar, Borneo, Java, New Guinea, and Taiwan. It was described by Francis Walker in 1855.
The wingspan is 20–30 mm for males. In the male, the head, thorax, and abdomen are brownish. Forewings are brown with an indistinct oblique sub-basal line. Waved antemedial and postmedial lines approach each other at the lower angle of the cell. The area between them is slightly tinged with bluish grey and has a waved dark line edged with white on each side of the discocellulars. Two indistinct, waved submarginal lines are present. The apex is slightly tinged with grey and has some subapical dark streaks. Hindwings are dark brown. The female is wingless.
Larvae are yellowish and clothed sparsely with brown hair. One dorsal and two lateral brown bands are seen. Paired tufts of hair are on the first and eleventh somites, projecting forward and backward. Lateral tufts of grey hair project from the fourth and fifth somites. Dorsal tufts of yellow hair are on the fourth to seventh somites. The head... Wikipedia →

With luck
About 10% of wildlife watchers report a Cocoa Tussock Moth sighting in Bengaluru on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 225th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
February, June–August and November
In those months about 10% of wildlife watchers report a Cocoa Tussock Moth in Bengaluru on a given day, against under 5% in March–May, September–October and December–January, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Cocoa Tussock Moth sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
9th of 10
Of the 10 cities where we can rate Cocoa Tussock Moth sightings, Bengaluru ranks 9th at about 10%. The best odds are in Taipei (Taiwan, about 20%), Taichung (Taiwan, about 20%) and Hong Kong (China, about 10%).
Same family: Erebidae
The closest relatives of the Cocoa Tussock Moth that you can see in Bengaluru (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Footman Moth (about 30%), Sandalwood Defoliator (about 20%) and Handmaiden Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cocoa Tussock Moth is recorded against all the insects logged in Bengaluru (16 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.
