Cupha erymanthis, the rustic, is a species of brush-footed butterfly found in forested areas of tropical South Asia and Southeast Asia. The males and females are identical. The upperside of the rustic is ochraceous light brown. Its forewing displays some loop-like, slender, dark cellular markings with a broad, somewhat curved, transverse yellow discal band from costa to vein 1. The band does not reach the termen but broadens posteriorly.
The margins of the forewing are irregularly sinuous, with the inner defined broadly with black, and produced outwards in interspaces 3 and 4. Below this, the margin is squarely indented inwards in interspace 2 and outwardly convex in interspace 1. There is a curved series of three black spots. The largest is in interspaces 1, 2 and 3. The apical area beyond the band is black, with a conspicuous yellow subapical spot in interspace 5, and a paler ill-defined similar spot above it in interspace 6. In the posterior, the black area is produced narrowly to the tornus and encircles a yellow spot near the apex of interspace 2.
The hindwing features a transverse sinuous and very slender black line. This line is followed by a... Wikipedia →

With luck
About 10% of wildlife watchers report a Rustic sighting in Dehradun on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 53rd most-seen of the 73 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
November and December
In those months about 30% of wildlife watchers report a Rustic in Dehradun on a given day, against under 5% in January–April and June–September, the lowest months. Those are among Dehradun's driest months, with about 10 mm of rain a month against 370 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Rustic sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 20
Of the 20 cities where we can rate Rustic sightings, Dehradun ranks 12th at about 10%. The best odds are in Thiruvananthapuram (India, about 30%), Thrissur (India, about 20%) and Ponnani (India, about 20%).
Same family: Nymphalidae
The closest relatives of the Rustic that you can see in Dehradun (family Nymphalidae, Brush-footed Butterflies) are Tawny Coster (about 40%), Lemon Pansy (about 30%) and Plain Tiger Butterfly (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rustic is recorded against all the insects logged in Dehradun (5 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.
