Cepora nerissa, the common gull, is a small to medium-sized butterfly of the family Pieridae, that is, the yellows and whites, which is native to Sri Lanka, India, China, southeast Asia, and Indonesia.

Forewing: veins black; apex and termen black, the inner margin of that colour extended in an irregular curve from middle of costa to base of terminal third of vein 4, thence continued obliquely outwards to the tornal angle; interspaces 6 and 9 with short narrow greyish-white streaks of the ground colour that stretch into the black apical area but do not reach the margin; a short black subterminal bar between veins 3 and 4 and another, less clearly defined, between veins 1 and 2. Hindwing: veins 4 to 7 with outwardly dilated broad black edgings that coalesce sometimes and form an anterior, irregular, black, terminal margin to the wing. Underside, forewing: white, the veins broadly margined on both sides by dusky black; costal margin broadly and apex suffused with yellow; subterminal black bars between... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Common Gull (butterfly) is recorded against all the insects logged in Mudumalai National Park (7 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.
