Under 5% of wildlife watchers report a Frosted Yellow sighting in Cévennes National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 993rd 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 20%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Frosted Yellow is recorded against all the insects logged in Cévennes National Park (14 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.
