Possible
About 20% of wildlife watchers report a Peak White sighting in Vanoise National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 44th most-seen of the 308 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Peak White in Vanoise National Park on a given day, against under 5% in September to May, 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.
Yes
Of the 3 parks where we can rate Peak White sightings, Vanoise National Park has the highest daily chance: about 20%. Next come Mercantour National Park (France, about 10%) and Pyrénées National Park (France, under 5%).
Same family: Pieridae
The closest relatives of the Peak White that you can see in Vanoise National Park (family Pieridae, Whites, Yellows, and Sulphurs) are Black-Veined White (about 30%), Mountain Clouded Yellow (about 20%) and Dark-Veined White (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Peak White is recorded against all the insects logged in Vanoise National Park (23 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.
