Marbled White

Melanargia galathea

Melanargia galathea, the marbled white, is a medium-sized butterfly in the family Nymphalidae. The marbled white was described in 1666 by C Merrett, and in 1695 James Petiver found a specimen in a wood near Hampstead and called it Papilio leucomelanus, our half-Mourner, to distinguish it from the Bath White, which Vernon (1702) had called the half-Mourner. It was also known as The Marmoris by Benjamin Wilkes and The Marmoress by Moses Harris. The butterfly was, also described in 1758, by the Swedish biologist and physician, Carl Linnaeus who formalised binomial nomenclature. Despite its common name and appearance, this butterfly is one of the "browns", of the subfamily Satyrinae. Source
