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 Bandhavgarh National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 12 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.
May
In that month about 50% of wildlife watchers report a Tawny Coster in Bandhavgarh National Park on a given day, against under 5% in March–April and December, the lowest months. That is one of Bandhavgarh National Park's driest months, with about 10 mm of rain against 400 mm in August. August has too few records to rate.
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.
2nd of 6
Of the 6 parks where we can rate Tawny Coster sightings, Bandhavgarh National Park ranks 2nd at about 30%. The best odds are in Nitmiluk National Park (Australia, about 40%).
Same family: Nymphalidae
The closest relatives of the Tawny Coster that you can see in Bandhavgarh National Park (family Nymphalidae, Brush-footed Butterflies) are Baronet (about 40%), Great Eggfly (about 40%) and Common Crow (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 Bandhavgarh National Park (7 verified sightings from 2019 to 2026), 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.
