Almost all of Europe to the Ural mountains. 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's 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 Northeast China to Japan. The occurrence in Japan however be regarded as subspecies (Idaea aversata japonica Inoue, 1955). A small, isolated occurrence in southern Turkey is remarkable.
The adults fly at night from June to August, occasionally later , and are attracted to light.
