Erysichton lineatus

Erysichton lineatus, the hairy line-blue, is a butterfly in the family Lycaenidae. It is the sole species of the genus Erysichton. It was first described by Richard Paget Murray in 1874. It is found in New Guinea and along most of the eastern coast of Australia, from Queensland to New South Wales.

The wingspan is about 20 mm. Adult females are brown with a large white patch on each forewing, and a blue sheen near the hinges. The hindwings have a black eyespot at the tornus. Adult males are blue.

The larvae feed on the flowers of Syzygium francisii, Ehretia acuminata, Macadamia integrifolia, Brachychiton acerifolium and Arytera lautereriana.
