Cirrochroa thais, also known as the Tamil yeoman, is a butterfly species of the nymphalidae family found in South India and Sri Lanka. It was first described under the scientific name Papilio thais by Danish zoologist Johann Christian Fabricius in 1787.
The butterfly has bright reddish yellow coloured wings measuring up to 60 to 75 mm (2.4 to 3.0 in). The wings are paler on the underside and feature a white spot in the middle. The wing tips are black and there are several small black spots on the wings. The The females have similar markings but are slightly paler in colour than the males.
In 2019, it was declared as the state butterfly of the Indian state of Tamil Nadu. The butterfly was first described under the name Papilio thais by Danish zoologist Johann Christian Fabricius in the Mantissa Insectorum in 1787. Jean-Baptiste Godart described it as Argynnis thea in the Encyclopédie Méthodique in 1819. It was moved to the genus Cirrochroa after Edward Doubleday established the new genus Cirrochroa in the The Genera of Diurnal Lepidoptera in 1847. Wikipedia →

Possible
About 20% of wildlife watchers report a Tamil Yeoman sighting in Ponnani on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 26th most-seen of the 76 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Tamil Yeoman in Ponnani on a given day, against under 5% in August and October–March, the lowest months. That is one of Ponnani's wettest months, with about 400 mm of rain against 10 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Tamil Yeoman 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 6 cities where we can rate Tamil Yeoman sightings, Ponnani has the highest daily chance: about 20%. Next come Kochi (India, about 20%) and Thrissur (India, about 20%).
Same family: Nymphalidae
The closest relatives of the Tamil Yeoman that you can see in Ponnani (family Nymphalidae, Brush-footed Butterflies) are Great Eggfly (about 30%), Grey Pansy (about 30%) and Tawny Coster (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tamil Yeoman is recorded against all the insects logged in Ponnani (12 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.
