Argyrotaenia ljungiana
In 3 days ~10% in a week ~30%
Argyrotaenia ljungiana is a moth of the family Tortricidae. It is found in Europe. The wingspan is 12–16 mm. Thorax has two hair-tufts. The species is quite variable in colour. The silver-white ground colour may be suffused with grey; and the usually red-brown markings may be close to black. The forewing tends to have three lighter cross-bands, the innermost of which sometimes has a square brown spot at the inner edge. The hindwings are grey-brown and the inner part of the wing fringe is bright so that there is a narrow, light strip along the outer edge. Julius von Kennel provides a full description.
The moth flies in two generations from April to August. The larvae feed on Ericaceae, Myrica gale and Vaccinium but have also been spotted feeding on grapes and apples. Wikipedia →

Rare
Under 5% of wildlife watchers report a Heather Tortrix sighting in Cévennes National Park on a given day, based on 11 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.
June to August
In those months about 10% of wildlife watchers report a Heather Tortrix 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 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Heather Tortrix 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.
Only Cévennes National Park, in our data
Cévennes National Park is the only park on Wallace's Line with enough records to rate Heather Tortrix sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Tortricidae
The closest relatives of the Heather Tortrix that you can see in Cévennes National Park (family Tortricidae, Tortricid Leafroller Moths) are Privet Tortrix (about 10%), Green Oak Tortrix (about 10%) and Codling Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Heather Tortrix is recorded against all the insects logged in Cévennes National Park (11 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.
