Rare
Under 5% of wildlife watchers report a Dun-Bar sighting in Cévennes National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 730th 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.
June and August–September
In those months about 10% of wildlife watchers report a Dun-Bar in Cévennes National Park on a given day, against under 5% in July and October–May, the lowest months.

Across all the parks we cover, that three-hour window holds the most Dun-Bar sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.

GBIF citizen-science records
It is estimated from how often the Dun-Bar is recorded against all the insects logged in Cévennes National Park (8 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.
