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 London on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1394th most-seen of the 1504 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow Belle in London on a given day, so our monthly data shows no clear season.
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.
4th of 4
Of the 4 cities where we can rate Yellow Belle sightings, London ranks 4th at under 5%. The best odds are in Madrid (Spain, about 10%), Istanbul (Turkey, about 10%) and Lisbon (Portugal, under 5%).
Same family: Geometridae
The closest relatives of the Yellow Belle that you can see in London (family Geometridae, Geometer Moths) are Riband Wave (about 20%), Least Carpet (about 20%) and Double-Striped Pug (about 20%), 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 London (5 verified sightings), 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.
