The garden carpet (Xanthorhoe fluctuata) is a moth of the family Geometridae. It is an abundant and familiar species across its huge range which covers the whole Palearctic region from Ireland to Japan and including the Near East and North Africa. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
It has a wingspan of 27–31 mm (1.1–1.2 in). The wings are greyish white with three irregular black blotches along the costa of the forewing, the largest in the middle. Occasionally, much darker (melanic) forms occur. "Easy to recognize, in spite of its variability. In the typical form the ground colour is dirty whitish and the median band is almost or altogether obsolete in its posterior half.
– ab. ochreata Prout has the ground colour ochreous. – In ab. neapolisata Mill, the ground colour is much darkened with brown-grey. – ab. costovata Haw. has the median band much narrowed and somewhat shortened, – deleta Ckll. is merely a rather extreme development of this and need not be separated.
– ab.immaculata Tutt is a much rarer aberration with the median band entirely wanting. – ab. abstersata H.-Sch. shows the opposite extreme of development... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Garden Carpet is recorded against all the insects logged in Snowdonia National Park (6 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.
