Rare
Under 5% of wildlife watchers report a Spindle Knot-Horn sighting in Pyrénées National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1144th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and September
In those months about 10% of wildlife watchers report a Spindle Knot-Horn in Pyrénées National Park on a given day, against under 5% in May–August and October–March, 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.
Among the best
Of the 2 parks where we can rate Spindle Knot-Horn sightings, Pyrénées National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Wadden Sea National Park (Germany, under 5%).
Same family: Pyralidae
The closest relatives of the Spindle Knot-Horn that you can see in Pyrénées National Park (family Pyralidae, Pyralid Snout Moths) are Rosy-Striped Knot-Horn (about 10%), Rosy Tabby (about 10%) and Long-Legged Tabby (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spindle Knot-Horn is recorded against all the insects logged in Pyrénées National Park (6 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.
