Euzophera pinguis, the tabby knot-horn, is a moth of the family Pyralidae. It was described by Adrian Hardy Haworth in 1811 and is found in Europe. The wingspan is 23–28 mm. The forewings are light brownish-ochreous, somewhat reddish-tinged, pale sprinkled, with a few blackish scales; lines hardly paler, first
rather curved, edged anteriorly by a broad blackish band, posteriorly by a thick blackish suffusion, second angulated in middle, strongly edged with dark fuscous; terminal area more infuscated. Hindwings light fuscous. The larva is pinkish ochreous; dorsal line darker, interrupted; a lateral spot on 3 and 12 ringed with reddish-brown; head and plate of 2 reddish-brown, blackish-marked: in bark of ash; 9–6, perhaps sometimes living two years.
The moths are on wing from July to August depending on the location. The larvae feed on Fraxinus excelsior. Wikipedia →

Rare
Under 5% of wildlife watchers report an Ash-Bark Knot-Horn sighting in Pyrénées National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 657th 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 30%, if each day is a fresh chance.
June and August
In those months about 10% of wildlife watchers report an Ash-Bark Knot-Horn in Pyrénées National Park on a given day, against under 5% in July and September–May, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Ash-Bark Knot-Horn 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.
Yes
Of the 2 parks where we can rate Ash-Bark Knot-Horn sightings, Pyrénées National Park has the highest daily chance: under 5%. Next come Wadden Sea National Park (Germany, under 5%).
Same family: Pyralidae
The closest relatives of the Ash-Bark 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 Ash-Bark Knot-Horn is recorded against all the insects logged in Pyrénées National Park (14 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.
