Description

This small and inconspicuous species is easily overlooked. The Dusky Knight occurs throughout northern and eastern Australia in open forest and woodland with a grassy understorey. The butterflies are usually fairly common and can often be found resting in the vegetation or on the ground where they are well camouflaged. As with many Satyridae, they are quite alert and difficult to approach.
