With luck
About 10% of wildlife watchers report a The Passenger sighting in Cévennes National Park on a given day, based on 87 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 108th most-seen of the 996 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June and July
In those months about 20% of wildlife watchers report a The Passenger in Cévennes National Park on a given day, against under 5% in October to April, the lowest months. Those are among Cévennes National Park's driest months, with about 60 mm of rain a month against 260 mm in October.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most The Passenger sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.

GBIF citizen-science records
It is estimated from how often the The Passenger is recorded against all the insects logged in Cévennes National Park (87 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.
