The willow beauty (Peribatodes rhomboidaria) is a moth of the family Geometridae. It is a common species of Europe and adjacent regions (Near East and the Maghreb). While it is found widely throughout Scandinavian countries, which have a maritime climate, it is absent from parts of the former USSR which are at the same latitude but have a more continental climate.
Peribatodes rhomboidaria rhomboidaria (Denis & Schiffermüller, 1775) Peribatodes rhomboidaria sublutearia (Zerny 1927) Under its junior synonym Geometra rhomboidaria, the willow beauty is the type species of its genus Peribatodes. This was initially proposed as a subgenus of Boarmia but eventually elevated to full genus rank.
The adult's wingspan is 40–48 mm. The wings of this species are whitish-grey or -yellowish, though they have a buff or grey appearance from a distance, as they are heavily speckled with brown or black dots... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Willow Beauty is recorded against all the insects logged in Budapest (38 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.
