Melanargia galathea, The marbled white, is a medium-sized butterfly in the family Nymphalidae.
Despite its common name and appearance, this butterfly is one of the "browns", of the subfamily Satyrinae.
This species can be found across most of Europe, southern Russia, Asia Minor and Iran. 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. The caterpillars feed on various grasses.
Distribution
This species can be found across most of Europe, southern Russia, Asia Minor and Iran. There is an isolated population in Japan.[verification needed] 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.
Habitat
It is found in forest clearings and edges, meadows and steppe where it occurs up to 1,500-1,700 m above sea level.[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.
Description
Melanargia galathea has a wingspan of 46–56 millimetres (1.8–2.2 in).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. Seitz - M. galathea. In the otherwise black cell of both wing an oval white spot which is not divided by a transverse bar. On the hindwing above the ocelli are quite invisible or shine through very faintly from the underside.
Life cycle
Like 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
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 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.

Okáč bojínkový (Melanargia galathea) je středně velký motýl z čeledi babočkovitých.
Okáč bojínkový dosahuje celkové velikosti 37–52 mm při délce předního křídla 23–28 mm.
Projevuje se u něj pohlavní dimorfismus, který je dobře pozorovatelný na spodní straně křídel – samci je mají bílé s šedou až černou kresbou a samice mají křídla žlutavá s hnědými skvrnami. Jak samci, tak samice mají na spodní straně křídel drobná očka, na svrchní straně jsou křídla černá s bílými skvrnami.
Rozšíření
Okáč bojínkový je v ČR běžný druh, který se vyskytuje až do nejvyšších poloh. Okáč bojínkový se vyskytuje na osluněných i podmáčených loukách a lesních paloucích, kde rostou pcháče, bodláky a chrpy, jejichž nektarem se motýli živí. Rozšířený je na evropském kontinentu, v severní Africe, jižní části Ruska (a na Kavkazu) a dokonce i v Íránu a Japonsku.
Životní cyklus
Motýli se vyskytují od konce května do srpna. Okáč bojínkový má jednu generaci ročně. Samičky kladou vajíčka tak, že prudce vzlétnou a zároveň vajíčko upustí do trávy. Housenky jsou charakteristické svým hustým ochlupením a mají zelenavě žlutou barvu. Žijí samostatně, přes den jsou ukryté u kořenů travin, kterými se živí (zejm. bojínku, kostřavy, sveřepu vzpřímeného nebo válečky), s večerem pak vylézají k žíru. Studené období roku přezimují a na jaře se kuklí přímo na rostlinách.

It is a common butterfly in Prague. I have photographed and observed many of them in the meadows above the Prokop valley.
Na území Prahy je to běžný motýl. Spoustu jsem jich fotil a pozoroval na loukách nad Prokopským údolím.

By the road in the Křivoklád forest. A lot of life takes place by the roads and in clearings.
There you can see animals grazing and insects flying in the sunlight, as various "flowers" grow in the light.
U cesty v Křivokládských lesích.Spousta života se odehrává právě u cest a na mýtinách.
Tam vidíte, jak se pase zvěř a na slunci létá hmyz, protože na světlu rostou různé "kytky".

I observed this one on the lower reaches of the Sázava River, where there are hundreds of cottages and gardens.
Toho jsem pozoroval na dolním toku Sázavy, kde jsou stovky chat a zahrádek.
