Cepora nadina, the lesser gull, is a small to medium-sized butterfly of the family Pieridae, that is, the yellows and whites. The species was first described by Hippolyte Lucas in 1852. It is native to Sri Lanka, India, Myanmar, Hainan, and southeast Asia.
Male has the upperside ground colour white. Forewing has the basal half of costal margin suffused with greenish yellow and irrorated (sprinkled) sparsely with black scales; apex from the middle of the costa and termen black, the inner margin of the black arched and acutely produced inwards along the veins, the black on the termen narrowed posteriorly and in interspaces 1a and 1 reduced to a mere thread. Hindwing: terminal margin with a broad dark band, due to the markings of the underside that show through by transparency, the darkness accentuated by a slight irroration of black scales; apices of some of the anterior veins black, in some specimens these are dilated and form a narrow anterior black border. Underside: white. Forewing: costal margin and apex very broadly suffused with greenish yellow and irrorated more or less densely with black scales, these latter form also diffuse subterminal...

Likely
About 40% of wildlife watchers report a Lesser Gull sighting in Royal Manas National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 27 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.
April
In that month about 60% of wildlife watchers report a Lesser Gull in Royal Manas National Park on a given day, against under 5% in March, the lowest month. July to October have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Lesser Gull 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 5 parks where we can rate Lesser Gull sightings, Royal Manas National Park has the highest daily chance: about 40%. Next come Namdapha National Park (India, about 40%) and Cuc Phuong National Park (Vietnam, about 40%). All parks ranked.
Same family: Pieridae
The closest relatives of the Lesser Gull that you can see in Royal Manas National Park (family Pieridae, Whites, Yellows, and Sulphurs) are Yellow Orange Tip (about 40%), Chocolate Albatross (about 40%) and Spotted Sawtooth (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lesser Gull is recorded against all the insects logged in Royal Manas National Park (15 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.
