It is found in most of Europe and northern Africa and east across the Palearctic to the Urals and the Altai Mountains. The species prefers meadow valleys, floodplains, waterside areas, bushy meadows and gardens. In the Alps it rises to 1500 metres. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Sandy Carpet is recorded against all the insects logged in Porto (15 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.
