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 Wadden Sea National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 630th 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 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report an Ash-Bark Knot-Horn in Wadden Sea National Park on a given day, against under 5% in September to July, 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.
Among the best
Of the 2 parks where we can rate Ash-Bark Knot-Horn sightings, Wadden Sea National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Pyrénées National Park (France, under 5%).
Same family: Pyralidae
The closest relatives of the Ash-Bark Knot-Horn that you can see in Wadden Sea National Park (family Pyralidae, Pyralid Snout Moths) are Long-Legged Tabby (about 10%), Rosy Tabby (about 10%) and Rosy-Striped Knot-Horn (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 Wadden Sea 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.
