In 3 days ~30% in a week ~50%
Ixias marianne, the white orange tip, is a small butterfly of the family Pieridae, (the yellows and whites) found in India and Sri Lanka. The characteristics of this species vary according to the season in which the eggs are laid.
The male has chalky-white wings with the apical half of the forewing and terminal margin of the hindwing broadly black. There is a broad, rich, orange patch obliquely across the black area extended to the upper apex of the forewing. At the lower apex this orange patch is very broad and leaves only the tip of the wing black along with a comparatively narrow band along the edge. The base of the wing is covered with black scales.
The underside of the wing is a rich sulphur-yellow as in other species of the genus, and is covered with reddish brown, short, transverse striations and minute dots. The forewing has an orange patch on the upperside which can be plainly seen because of the transparency on the wing, a broadly triangular area below this cell white, large and prominent discocellular spots with a white centre. Both forewings and hindwings have a discal transverse series of reddish-brown spots, more or less conspicuous... Wikipedia →

With luck
About 10% of wildlife watchers report a White Orange Tip sighting in New Delhi on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 54th most-seen of the 174 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a White Orange Tip in New Delhi on a given day, against under 5% in February–March, June and December, the lowest months. That is one of New Delhi's wettest months, with about 120 mm of rain against almost none in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White 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.
3rd of 7
Of the 7 cities where we can rate White Orange Tip sightings, New Delhi ranks 3rd at about 10%. The best odds are in Pune (India, about 20%) and Nashik (India, about 20%).
GBIF citizen-science records
It is estimated from how often the White Orange Tip is recorded against all the insects logged in New Delhi (32 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.
