Eupithecia haworthiata, or Haworth's pug, is a moth of the family Geometridae. The species was first described by Henry Doubleday in 1856. It can be found in western, south and central Europe, Asia Minor, the Caucasus and east across the Palearctic to Amur. It occurs in the Alps up to 1800 meters, in the Apennines up to 1400 metres and in the Balkan mountains up to 1500 m above sea level.
The wingspan is 12–14 mm. The ground colour of the forewings is grey brown. The crosslines are in pairs. A central spot is missing. There is a faint discal stain on the hindwings. The colour of the first abdominal segments is strongly yellow, orange or reddish.
The moths flies from April to August depending on the location. The caterpillars feed on Clematis vitalba and cultivated Clematis species. The pupa hibernates and often 2 or even 3 winters are passed in this state. Eupithecia haworthiata haworthiata

Rare
Under 5% of wildlife watchers report a Haworth's Pug 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 1026th 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.
May and June
In those months about 10% of wildlife watchers report a Haworth's Pug in Pyrénées National Park on a given day, against under 5% in July to April, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Haworth's Pug sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Pyrénées National Park, in our data
Pyrénées National Park is the only park on Wallace's Line with enough records to rate Haworth's Pug sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Haworth's Pug 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.
