Cyclophora porata

Cyclophora porata, the false mocha, is a moth of the family Geometridae. It is found in southern Europe and from England to Denmark, southern Sweden and the Caucasus. The wingspan is 25 to 30 millimetres. The forewings are a warm reddish orange-brown while the hindwings are clearly lighter, and both wings carry abundant grey scales that give them a shining look. Each wing bears a clear central spot made of a dark ring with a white centre, the inner and outer cross-lines are broken into a row of separate black dots, and the greyish middle crossband blends into the ground colour without a clear edge. In western Europe the moths fly in two generations, from May to June and from August to September. The caterpillars can be green or brownish yellow and feed on oak and birch. The species is hard to tell with certainty from its close relatives in the genus, which include Blair's mocha, the Jersey mocha, the maiden's blush and the clay triple-lines.
