Cerastis leucographa, the white-marked, is a moth of the family Noctuidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in most of Europe, east to Russia, through the Palearctic up to Japan.

Biology
Adults are on wing from March to June depending on the location. It occurs up to about 1500 meters altitude. It is found in different habitats, for example in mixed forest edges, clearings, bushy valleys, forest bogs and moors. There is one generation per year whose moths fly from March to May. They are dusk and nocturnal and visit artificial light sources and the bait. They suck on flowering catkins, their very early flight time runs largely parallel to the willow blossom (Salix).

The larvae feed on Vaccinium myrtillus, Prunus spinosa and Salix, Rumex, Rhinanthus and Galium species.
