Idaea rusticata, the least carpet, is a moth of the family Geometridae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. This species can be found in most of Europe, in the Near East and in North Africa. From the Balkan Peninsula, the occurrence continues across the Palearctic though Ukraine, southern Russia and Asia Minor to the Caucasus and from there via northern Iran, Afghanistan, Turkmenistan, Kyrgyzstan to the Central Asian mountains as far as Mongolia. Of all moths in Britain it showed the greatest percentage increase in abundance between 1968 and 2007, and expanded its range beyond the vicinity of London.
These moths inhabit wastelands, open places, parks and well exposed gardens. Idaea rusticata has a wingspan of 19–21 mm. The length of the forewings is 9–11 mm. The edges of the wings are fringed. The basic colour is whitish or cream, sometimes with a very light brownish tone. The upperside of the forewings shows in the midfield a dark brown to red-brown transverse drawing, with a point-shaped black spot, always within the dark field. This brown marking runs from the front to the rear edge... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Least Carpet is recorded against all the insects logged in Kiskunság National Park (10 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.
