Polyura athamas, the common nawab, is a species of fast-flying canopy butterfly found in tropical Asia. It belongs to the Charaxinae (rajahs and nawabs) in the brush-footed butterfly family (Nymphalidae). It occurs in the Himalayas from Kashmir to Sikkim, the hills of central India and the Eastern Ghats, the Western Ghats and southern India, Sri Lanka, Assam, Cachar, and via Myanmar, Cambodia and the Tenasserim Hills far into Indonesia. In August 2016 a specimen was spotted and caught in Palawan, Philippines.
Male and female. Upperside black. Forewings and hindwings with a discal broad transverse area from below vein 4 in forewing to vein 2 on hindwing, a moderately large spot in interspace 5, a minute preapical dot beyond in interspace 6 on forewing, and a subterminal row of spots with two or three spots beyond them on the tornal angle of the hindwing, pale yellow, sometimes with an ochraceous, sometimes with a greenish tinge.
The discal area on the forewing is nearly as broad in interspace 3 as on the dorsum, on the hindwing narrowing to an acute point on vein 2 at two-thirds of its length from the base of the wing. Tails are touched with bluish grey. Underside... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Nawab sighting in Guangzhou on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 197th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June–July and September–October
In those months about 10% of wildlife watchers report a Common Nawab in Guangzhou on a given day, against under 5% in August and November–May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Nawab sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Common Nawab sightings, Guangzhou ranks 3rd at under 5%. The best odds are in Chattogram (Bangladesh, about 20%) and Hong Kong (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Nawab is recorded against all the insects logged in Guangzhou (14 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.
