Under 5% of wildlife watchers report a Mottled Beauty sighting in Cévennes National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 896th most-seen of the 996 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Mottled Beauty in Cévennes National Park on a given day, against under 5% in September to June, the lowest months. Those are among Cévennes National Park's driest months, with about 45 mm of rain a month against 260 mm in October.

GBIF citizen-science records
It is estimated from how often the Mottled Beauty is recorded against all the insects logged in Cévennes National Park (5 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.
