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 20% of wildlife watchers report a Tawny Coster sighting in Mysuru on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 95 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.
February and March
In those months about 30% of wildlife watchers report a Tawny Coster in Mysuru on a given day, against under 5% in January, May, September and November, the lowest months. Those are among Mysuru's driest months, with about 10 mm of rain a month against 140 mm in September.
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.
43rd of 52
Of the 52 cities where we can rate Tawny Coster sightings, Mysuru ranks 43rd at about 20%. 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 Mysuru (family Nymphalidae, Brush-footed Butterflies) are Plain Tiger Butterfly (about 30%), Lemon Pansy (about 30%) and Common Crow (about 20%), 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 Mysuru (17 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.
