The large skipper (Ochlodes sylvanus) is a butterfly of the Hesperiidae family, which occurs throughout Europe. It was long known as Ochlodes venatus, but this is a Far Eastern relative. There is still some dispute whether this species should be considered a distinct species or included in O. venatus as a subspecies. Under ICZN rules the specific name, originally proposed as Papilio sylvanus, is invalid as a homonym (of the butterfly now called Anthene sylvanus), but is has been conserved by an ICZN commission decision in 2000.
