Acraea terpsicore, the tawny coster, is a small, 53–64 millimetres (2.1–2.5 in), leathery-winged butterfly common in grassland and scrub habitats. It belongs to the Nymphalidae or brush-footed butterfly family. It has a weak fluttery flight. It is avoided by most insect predators. This species and the yellow coster (Acraea issoria) are the only two Indian representatives of the predominantly African tribe Acraeini. It is found in India, Sri Lanka, Indonesia, Maldives to Myanmar, Thailand, Laos, Cambodia, Vietnam, Bangladesh, Malaysia, Singapore, and recently Australia.
Pierre and Bernaud, in 1997, stated that they verified the type in the Linnean Society of London and considered A. violae the same species as A. terpsicore. Honey and Scoble, in 2001, argued that both specimens in the Linnean Society are later additions by James Edward Smith (botanist) who, in 1784, purchased Linnaeus specimens, bringing them to London.

Possible
About 30% of wildlife watchers report a Tawny Coster sighting in Pune on a given day, based on 339 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 340 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April and May
In those months about 50% of wildlife watchers report a Tawny Coster in Pune on a given day, against about 10% in January and October–November, the lowest months. Those are among Pune's driest months, with about 15 mm of rain a month against 520 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Tawny Coster sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
16th of 52
Of the 52 cities where we can rate Tawny Coster sightings, Pune ranks 16th at about 30%. The best odds are in Puducherry (India, about 50%), Yogyakarta (Indonesia, about 40%) and Rajkot (India, about 40%).
Same family: Nymphalidae
The closest relatives of the Tawny Coster that you can see in Pune (family Nymphalidae, Brush-footed Butterflies) are Plain Tiger Butterfly (about 30%), Common Evening Brown (about 30%) and Lemon Pansy (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tawny Coster is recorded against all the insects logged in Pune (339 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.
