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 Moscow on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 434th most-seen of the 1111 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.
August
In that month about 10% of wildlife watchers report a Blotched Marble in Moscow on a given day, against under 5% in September to July, the lowest months.
Among the best
Of the 2 cities where we can rate Blotched Marble sightings, Moscow ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Blotched Marble is recorded against all the insects logged in Moscow (21 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.
