Rare
Under 5% of wildlife watchers report a Green Silver-Lines 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 Green Silver-Lines 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.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Green Silver-Lines sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
4th of 4
Of the 4 parks where we can rate Green Silver-Lines sightings, Cévennes National Park ranks 4th at under 5%. The best odds are in Bavarian Forest National Park (Germany, about 10%), Snowdonia National Park (United Kingdom, about 10%) and Pyrénées National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Green Silver-Lines 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.
