With luck
About 10% of wildlife watchers report a Citrus Looper sighting in Cévennes National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 493rd most-seen of the 996 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Citrus Looper in Cévennes National Park on a given day, against under 5% in September to May, 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 midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Citrus Looper sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Cévennes National Park, in our data
Cévennes National Park is the only park on Wallace's Line with enough records to rate Citrus Looper sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Citrus Looper that you can see in Cévennes National Park (family Geometridae, Geometer Moths) are Willow Beauty (about 20%), Portland Ribbon Wave (about 10%) and Chimney-Sweeper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Citrus Looper is recorded against all the insects logged in Cévennes National Park (17 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.
