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.
There is a single generation, flying between mid-June to mid-August.
Eggs are dropped on the ground amongst vegetation where Sheep's Fescue, Red Fescue and Tor-grass grow..
It is now becoming more widespread across all three counties.
