The Marbled White Butterfly is quite distinctive with its black and white colours it is unlikely to be mistaken for any other species of butterfly. During July it can be found flying around unimproved grasslands and often occurs in large numbers on southern downloads. Apparently it shows a preference for purple flowers such as Field Scabious, thistles and knapweeds.
It is widespread in southern Britain but has expanded north and eastwards recently.
It is from the family ‘Browns’ and is medium in size with a wing span between 50-60mm.
