The Marbled White (Melanargia galathea) is a butterfly in the family Nymphalidae. Found across most of Europe, south Russia, Asia Minor and Iran. There is an isolated population in Japan. It is not found in Ireland, North Britain, Scandinavia (except Denmark) and Portugal or Spain.
Despite its common name and appearance, this butterfly is one of the "browns", of the subfamily Satyrinae.
Found in forest clearings and edges, meadows and steppe.Occurs up to 1,500-1,700 m above sea level.hey are a common sight in unimproved grasslands across southern Britain, particularly on the South Downs.
Like other members of its subfamily, the larvae feed on various grasses.These include Phleum (Phleum pratense), Poa (Poa annua, Poa trivalis), Festuca rubra, Bromus erectus, Dactylis, Brachypodium pinnatum, Agrostis capillaris. It is thought that Red Fescue Festuca rubra is essential in their diet.?
Eggs are laid on the wing, or from brief perches on grass stems, and are just sprinkled among the grass stems. Upon hatching, the larvae immediately enter hibernation, and only feed the following spring when the fresh growth occurs. They are a lime green colour, with a dark green line running down the middle of their back. Pupation takes place at ground level in a loose cocoon. Adults emerge in July, and, on a good site, in warm, sunny weather, thousands can be seen gently fluttering amongst the grass heads.
