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 →

With luck
About 10% of wildlife watchers report a Yellow Belle sighting in Istanbul on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 266 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March–May and September
In those months about 10% of wildlife watchers report a Yellow Belle in Istanbul on a given day, against under 5% in June–August and October–February, 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.
Among the best
Of the 4 cities where we can rate Yellow Belle sightings, Istanbul ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Madrid (Spain, about 10%).
Same family: Geometridae
The closest relatives of the Yellow Belle that you can see in Istanbul (family Geometridae, Geometer Moths) are Double-Striped Pug (about 10%), Willow 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 Istanbul (10 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.
