In 3 days ~20% in a week ~30%
Pontia daplidice, the Bath white, is a small butterfly of the family Pieridae, the yellows and whites, which occurs in the Palearctic region. It is common in central and southern Europe, migrating northwards every summer, often reaching southern Scandinavia and sometimes southern England.
The Bath white is a small white butterfly with a wingspan of 45 to 50 mm. The underside of the hindwing has a pattern of greenish blotches, which is characteristic of the Bath whites and easily identifies it from other pierids.
Sexes can be differentiated by markings on the forewing. The male is differentiated from the female by the markings on the upperside of the forewing. The apex of the forewing is black with white spots and lines. There is a black spot at the end of the cell. In the case of the female, there is an additional discal spot in 1b. The female also has an obscure row of terminal and marginal spots on the upper hindwing.
Description from C. T. Bingham in The Fauna of British India, Including Ceylon and Burma, "Butterflies Volume 2" (1907). Male: Upperside: white. Forewing: basal half of costa narrowly irrorated with black scales, a broad irregular quadrate black spot... Wikipedia →

With luck
About 10% of wildlife watchers report a Bath White sighting in Cévennes National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 619th most-seen of the 996 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Bath White is recorded against all the insects logged in Cévennes National Park (9 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.
