In 3 days ~10% in a week ~20%
The bordered white or pine looper (Bupalus piniaria), is a moth of the family Geometridae. Among these, it belongs to tribe Bupalini of the subfamily Ennominae. B. piniaria is a common species throughout the western Palearctic region, the Near East and North Africa. However, its presence in certain regions – e.g. the northern Balkans – is doubtful. East it is found to Siberia
and Amur Oblast. This moth is an inhabitant of coniferous woodland. The adults fly in May and June, sometimes later (up to August or so) in the north of the range. Their wingspan is 34–40 mm. This is a variable species with strong sexual dimorphism, always conspicuous in the antennae which are combed in the males and plain in the females... Wikipedia →

Rare
Under 5% of wildlife watchers report a Bordered White sighting in Essen on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 347th most-seen of the 434 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.
June
In that month about 10% of wildlife watchers report a Bordered White in Essen on a given day, against under 5% in July to May, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Bordered White sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Essen, in our data
Essen is the only city on Wallace's Line with enough records to rate Bordered White sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Geometridae
The closest relatives of the Bordered White that you can see in Essen (family Geometridae, Geometer Moths) are Riband Wave (about 20%), Double-Striped Pug (about 10%) and Willow Beauty (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bordered White is recorded against all the insects logged in Essen (6 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.
