Dysstroma citrata, the dark marbled carpet or northern marbled carpet, is a moth of the family Geometridae. It is found across the Holarctic ecozone. It has also been reported from India. The wingspan is 25–32 mm. The ground colour of the forewings may show whitish, grey, black or brown tints but the colour is extremely variable and there are strongly darkened forms. Characteristic is the protruding post medial line on the front wings, which usually reaches the post discal wavy line or interrupts it. Very similar to Dysstroma truncata. Adults are on wing from July to August
