In 3 days ~50% in a week ~80%
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 →

Possible
About 20% of wildlife watchers report a Yellow Belle sighting in Monfragüe National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 84 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Yellow Belle in Monfragüe National Park on a given day, against under 5% in June–August and October–February, the lowest months. That is one of Monfragüe National Park's wettest months, with about 70 mm of rain against almost none in July.
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.
Yes
Of the 5 parks where we can rate Yellow Belle sightings, Monfragüe National Park has the highest daily chance: about 20%. Next come Doñana National Park (Spain, about 10%) and Sierra de Guadarrama National Park (Spain, about 10%).
Same family: Geometridae
The closest relatives of the Yellow Belle that you can see in Monfragüe National Park (family Geometridae, Geometer Moths) are Lydd Beauty (about 10%) and Vestal (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow Belle is recorded against all the insects logged in Monfragüe National Park (18 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.
