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

GBIF citizen-science records
It is estimated from how often the Bordered White is recorded against all the insects logged in Sierra de Guadarrama National Park (11 verified sightings from 2019 to 2026), 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.
