The Marbled White is widespread in southern England and has been extending its range northwards and eastwards in recent years. It is found in areas of unimproved flowery grassland, as well as disused railway lines, roadside verges and waste ground.


The Marbled White is unmistakeable due to its distinctive black and white markings.
