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 Taichung on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 129th most-seen of the 197 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June–July, September and December–February
In those months about 10% of wildlife watchers report a Rustic in Taichung on a given day, against under 5% in March–May, August and October–November, the lowest months.
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.
17th of 20
Of the 20 cities where we can rate Rustic sightings, Taichung ranks 17th 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 Taichung (family Nymphalidae, Brush-footed Butterflies) are Great Eggfly (about 20%), Plain Tiger Butterfly (about 20%) and Common Palmfly (about 20%), 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 Taichung (8 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.
