(=Pieris kalora, Moore, P.Z.S. 1865:449) Upperside: white Forewing: black at extreme bases of interspaces 1a and 1 and of cell; discocellulars marked with a quadrate black spot; a discal curved series of inwardly dentate spots, the spots in interspaces 1 and 2 generally reduced to a mere trace, often absent; an anterior terminal series of similar but more clearly defined spots at the apices of veins 3 to 7.
Hindwing: uniform, the pattern of the underside visible through transparency; base densely irrorated (sprinkled) with black scales. Underside Forewing: white; basal half of costal margin and quadrate spot on discocellulars dull black; a discal curved series of four black spots in interspaces 1, 3, 5 and 6, followed by elongate streaks of green along veins 3 to 7 that extend to the termen.

Rare
Under 5% of wildlife watchers report a Peak White sighting in Pyrénées National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1026th most-seen of the 1277 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.
July
In that month about 10% of wildlife watchers report a Peak White in Pyrénées National Park on a given day, against under 5% in August to June, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Peak White sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Peak White sightings, Pyrénées National Park ranks 3rd at under 5%. The best odds are in Vanoise National Park (France, about 20%) and Mercantour National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Peak White is recorded against all the insects logged in Pyrénées National Park (6 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.
