The large skipper (Ochlodes sylvanus) is named for its quick, darting flight habits. Skippers are the intermediate form lying between butterflies and moths – skippers are characterised by their stout bodies and small heads just like that of a moth. Males have a thick black line through the centre of fore-wing. The presence of a faint chequered pattern on both sides of the wings distinguishes this species from the similar Small and Essex Skippers, which fly at the same time.
