Melanargia galathea has a wingspan of 46–56 millimetres  In these medium-sized butterflies the upper side of the wings is decorated with white and gray-black or dark brown markings, but it is always gray-black or dark brown checkered in the basal and distal areas. The underside is similar to the upper side but the drawings is light gray or light brown. On the underside of the hindwings is present a row of gray eye spots. The males and the females are quite similar, except that some females may have a yellowish nuance on the underside of the wings.\nLife cycle:\nLike other members of its subfamily, the larvae feed on various grasses. These include Phleum (P. pratense), Poa (P. annua, P. trivalis), Festuca rubra, Bromus erectus, Dactylis, Brachypodium pinnatum, Agrostis capillaris, Elytrigia, Holcus, Dactylis, Triticum and Agropyron species . \nEggs 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 can be found from early June to early September. On a good site, in warm, sunny weather, thousands can be seen gently fluttering amongst the grass heads.\nHabitat:\nIt is found in forest clearings and edges, meadows and steppe where it occurs up to 1,500-1,700 m above sea level. They are a common sight in unimproved grasslands across Europe.\n\nDistribution:\nThis species can be found across most of Europe, southern 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. The late twentieth century saw an expansion of its range in the UK (source Wikipedia). \n\nThis Picture is made during a Long Weekend in the South of Belgium in June 2019.
