Ixias pyrene, the yellow orange tip, is a small butterfly of the family Pieridae, that is, the yellows and whites, which is found in Sri Lanka, India and southeast Asia. The species wingspan is between 50 and 55 mm. Dry-season brood: Male upperside: deep sulphur-yellow. Forewing: base and basal half of costa thickly irrorated with black scales; apical half of the wing black, with an enclosed, large, irregularly triangular, orange-coloured patch, the apex of which is more or less broadly rounded and blunt; the orange colour extends into the apex of the cell but is interrupted there by a black discocellular spot that spreads diffusely inwards and joins the black oblique bar which forms the base of the orange patch; veins that traverse this latter, black. Hindwing: uniform with a little black scaling at extreme base; termen with a dusky-black somewhat narrow border (sometimes entirely absent) which decreases in width posteriorly.
Underside: a darker yellow, sparsely irrorated (sprinkled) with fusco-ferruginous short strigae and minute spots. Forewing: base and posterior area broadly, with a whitish pale virescent (greenish) tint; the strigae and minute spots most numerous... Wikipedia →

Possible
About 30% of wildlife watchers report a Yellow Orange Tip sighting in Kaeng Krachan National Park on a given day, based on 86 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 296 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Yellow Orange Tip is recorded against all the insects logged in Kaeng Krachan National Park (86 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.
