The riband wave (Idaea aversata) is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is an abundant species in Europe, the Near East and North Africa and across the Palearctic. Records are few in the Iberian Peninsula and the Balkan Peninsula. The north border is northern Sweden and northern Finland. The northernmost parts of Russia and a few areas of Russia, northwest of the Caspian Sea are excluded. In North Africa (eastern Algeria and Tunisia), there is a smaller presence belonging to a separate subspecies (Idaea aversata indeviata Prout, 1935). Outside Europe, the distribution area extends from northern Turkey up to the Caucasus, from there via Central Asia, Siberia and north-east China to Japan. The occurrence in Japan is regarded as subspecies (Idaea aversata japonica Inoue, 1955). A small, isolated occurrence in southern Turkey is remarkable.
The species has a wingspan of 30–35 mm. Its distinctive outline is familiar at lighted windows. The wings are buff or cream with dark fasciae (bands). Two main forms exist, equally abundant: one has darker shading between... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Riband Wave is recorded against all the insects logged in Kyiv (56 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.
