Also known as Our Half-Mourner, Marmoris, Marbled Argus and Marbled-White Half Mourner. 
   They prefer unimproved grassland with high grasses.
   The strongest populations are found on chalk or limestone grasslands but other habitats such as; woodland rides and clearings, coastal grassland, road verges and railway embankments are also popular.
   They are generally only found in the countryside, and are rarely seen in gardens.
   Adults are generally flying in the summer, from June to August.
   Marbled Whites have a black-and-white checked pattern on both dorsal and ventral sides that is unforgettable.
   Males and females are alike on the upper wings.

Female hind ventral wings tend to be brownish, though the hind dorsal wings remain black and white, with a pale brown leading edge.

   Marbled Whites live in distinct and often quite large colonies.

   Despite its name, the Marbled White is more closely related to the subfamily known as the "browns" than it is to the "whites".

The single biggest threat to butterfly survival is habitat destruction!!
