Rare
Under 5% of wildlife watchers report a Rose Tortrix Moth sighting in Wadden Sea National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 486th most-seen of the 818 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
In that month about 10% of wildlife watchers report a Rose Tortrix Moth in Wadden Sea National Park on a given day, against under 5% in August to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Rose Tortrix Moth sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 2
Of the 2 parks where we can rate Rose Tortrix Moth sightings, Wadden Sea National Park ranks 2nd at under 5%. The best odds are in Bavarian Forest National Park (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Rose Tortrix Moth is recorded against all the insects logged in Wadden Sea National Park (21 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.
