Melanargia galathea

It is found in forest clearings and edges, meadows and steppe where it occurs up to 1,500–1,700 metres (4,900–5,600 ft) above sea level.

[verification needed] It is not found in Ireland, North Britain, Scandinavia (except Denmark) and Portugal or Spain.

[4] They are a common sight in unimproved grasslands across southern Britain, particularly on the South Downs, but also extending slightly further north to places such as the Dunstable Downs, Devil's Dyke near Newmarket, Fleam Dyke, Les King Wood near the South Cambs village of Cottenham, The "Edwards" wood, Dry Drayton.

This species is rather similar to the Iberian marbled white (Melanargia lachesis) that replaces M. galathea in Spain and southern France.

These include Phleum (P. pratense), Poa (P. annua, P. trivalis), Festuca rubra, Bromus erectus, Dactylis, Brachypodium pinnatum, Agrostis capillaris, Elymus (syn.

Upon hatching, the larvae immediately enter hibernation and only feed the following spring when the fresh growth occurs.

The marbled white was called "Our Half-mourner" by James Petiver (1717), "The Marmoris" by Benjamin Wilkes and "The Marmoress" by Moses Harris.
