The mottled beauty (Alcis repandata) is a moth of the family Geometridae. It is a common species of Europe and the Near East. The wingspan is 32–40 mm. This is an extremely variable species, typically being buff or grey with black bars along the costa, but often with a broad blackish band across the forewings. Melanic forms are also common, especially in industrial areas. In all but the darkest variations the most characteristic feature is a pale "zig-zag" line across the hindwing. This moth flies at night in June and July and is attracted to light.
