Endothenia quadrimaculana
In 3 days ~10% in a week ~20%
Endothenia quadrimaculana is a moth of the family Tortricidae. It is found from northern and central Europe to Siberia and south-eastern Russia, Mongolia and China. Subspecies nubilana is found in North America. The wingspan is 18–22 mm. The ground colour of the forewings is light brown with small dark brown spots along the costal edge, a square brown spot in the middle of the wing and an inward-curved brown cross-band at the tip. The hindwings are light brown. Dissection of the genitalia is necessary to determine Endothenia species with certainty.
In France and Switzerland, there are two generations per year. Adults are on wing in May and June and again in August and September. The larvae feed on Mentha spicata, Mentha arvensis, Lamium album, Stachys palustris, Stachys arvensis, Stachys recta and Symphytum officinale. Wikipedia →

Rare
Under 5% of wildlife watchers report a Blotched Marble sighting in Helsinki on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 665th most-seen of the 838 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.
July
In that month about 10% of wildlife watchers report a Blotched Marble in Helsinki on a given day, against under 5% in August to June, the lowest months.
Yes
Of the 2 cities where we can rate Blotched Marble sightings, Helsinki has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
Same family: Tortricidae
The closest relatives of the Blotched Marble that you can see in Helsinki (family Tortricidae, Tortricid Leafroller Moths) are Barred Marble (about 10%), Common Marble (about 10%) and White-Foot Bell (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blotched Marble is recorded against all the insects logged in Helsinki (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.
