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. ==Description== It has a wingspan of 27–31 mm. 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 of the band, which is here darkened completely across the wing; distal area also sometimes darkened. * - ''thules'' Prout is a dark race from the Shetland Islands. The less extreme forms intergrade into ab. ''neapolisata'', but the name strictly applies to specimens in which both the fore- and the hindwing are entirely infuscated so that the markings are almost obliterated. * - ''sempionaria'' Rätzer is a small race from the Simplon, of a rather purer white than the type and with the median half-band rather small but rather sharply marked."〔Prout , L.B. 1912–16.
