Cleora cinctaria, the ringed carpet, is a moth of the family Geometridae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found from Europe to southern Siberia, Turkey, the Caucasus, central Asia and Mongolia. It is also found in Japan.
The wingspan is 28–35 mm. The wings have a light grey ground colour. The lines are brown. The intensity of the grey or brown colouration varies quite strongly. The interior crossline is band-like and widened basally, the exterior crossline is curved towards the front edge and is usually double. The brownish darkened margin has a white wavy line and white dusting. On the hindwings are dark lines and an often indistinct whitish squiggle. The first abdominal segment appears in the form of a white belt. The antennae of the males are combed on both sides, those of the females are filiform. Prout gives an account of named forma. The larva is smooth, light green with bluish green and white longitudinal lines.
Adults are on wing from April to May. The larvae feed various plants and trees, including Betula (including Betula verrucosa), Myrica gale, Carex, Salix, Populus tremula, Rubus idaeus, Sorbus aucuparia, Vicia cracca, Rhamnus frangula, Lysimachia vulgaris, Vaccinium myrtillus and Galium verum.

Rare
Under 5% of wildlife watchers report a Ringed Carpet sighting in Saint Petersburg on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 377th most-seen of the 448 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Ringed Carpet in Saint Petersburg on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Ringed Carpet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 cities where we can rate Ringed Carpet sightings, Saint Petersburg ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Nizhny Novgorod (Russia, under 5%), Helsinki (Finland, under 5%) and Yekaterinburg (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Ringed Carpet is recorded against all the insects logged in Saint Petersburg (5 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.
