Aspitates ochrearia, the yellow belle, is a moth in the family Geometridae. The species was first described by Pietro Rossi in 1794. It is found in western and southern Europe, as well as North America. The wingspan is 25–34 mm. Adults are on wing from April to June and again from August to September in two generations per year. It is very similar to Aspitates gilvaria.
The larvae feed on various herbaceous plants, including Daucus carota and Plantago coronopus. The larvae can be found from April to June. The species overwinters in the larval stage. Pupation takes place in spring. Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellow Belle sighting in Pyrénées National Park on a given day, based on 5 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.
May and September
In those months about 10% of wildlife watchers report a Yellow Belle in Pyrénées National Park on a given day, against under 5% in June–August and October–April, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Yellow Belle sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
5th of 5
Of the 5 parks where we can rate Yellow Belle sightings, Pyrénées National Park ranks 5th at under 5%. The best odds are in Monfragüe National Park (Spain, about 20%), Doñana National Park (Spain, about 10%) and Sierra de Guadarrama National Park (Spain, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow Belle is recorded against all the insects logged in Pyrénées National Park (5 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.
