With luck
About 10% of wildlife watchers report a Peak White sighting in Mercantour National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 307th most-seen of the 412 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.
June
In that month about 20% of wildlife watchers report a Peak White in Mercantour 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.
2nd of 3
Of the 3 parks where we can rate Peak White sightings, Mercantour National Park ranks 2nd at about 10%. The best odds are in Vanoise National Park (France, about 20%).
GBIF citizen-science records
It is estimated from how often the Peak White is recorded against all the insects logged in Mercantour 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.
