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.

Likely
About 40% of wildlife watchers report a Tawny Coster sighting in Nitmiluk National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 17 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 70% of wildlife watchers report a Tawny Coster in Nitmiluk National Park on a given day, against under 5% in July, the lowest month. That is one of Nitmiluk National Park's driest months, with almost no rain against 270 mm in January.
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.
Yes
Of the 6 parks where we can rate Tawny Coster sightings, Nitmiluk National Park has the highest daily chance: about 40%. Next come Bandhavgarh National Park (India, about 30%) and Ranthambore National Park (India, about 20%).
Same family: Nymphalidae
The closest relatives of the Tawny Coster that you can see in Nitmiluk National Park (family Nymphalidae, Brush-footed Butterflies) are Blue Pansy (about 40%), Australian Common Crow (about 40%) and Orange Ringlet (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 Nitmiluk National Park (21 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.
