Rare
Under 5% of wildlife watchers report a Spindle Knot-Horn sighting in Wadden Sea National Park on a given day, based on 9 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.
June to August
In those months about 10% of wildlife watchers report a Spindle Knot-Horn in Wadden Sea National Park on a given day, against under 5% in September to May, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Spindle Knot-Horn 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.
Yes
Of the 2 parks where we can rate Spindle Knot-Horn sightings, Wadden Sea National Park has the highest daily chance: under 5%. Next come Pyrénées National Park (France, under 5%).
Same family: Pyralidae

GBIF citizen-science records
It is estimated from how often the Spindle Knot-Horn is recorded against all the insects logged in Wadden Sea National Park (9 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.
