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 →

Rare
Under 5% of wildlife watchers report a Yellow Orange Tip sighting in Bangkok on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 186th most-seen of the 245 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Yellow Orange Tip in Bangkok on a given day, against under 5% in December to October, the lowest months. That is one of Bangkok's driest months, with about 40 mm of rain against 280 mm in September.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Yellow Orange Tip sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 11
Of the 11 cities where we can rate Yellow Orange Tip sightings, Bangkok ranks 10th at under 5%. The best odds are in Agra (India, about 20%), New Delhi (India, about 20%) and Mumbai (India, about 20%).
Same family: Pieridae
The closest relatives of the Yellow Orange Tip that you can see in Bangkok (family Pieridae, Whites, Yellows, and Sulphurs) are Painted Jezebel (about 20%), Lemon Migrant (about 10%) and Western Striped Albatross (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow Orange Tip is recorded against all the insects logged in Bangkok (7 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.
