Banks’ Brown is a typical and common species of open forests in the montane areas of south-eastern Australia. It can be distinguished from similar species of the genus Heteronympha by the characteristic pattern of orange patches on the upperside as well as the strong purple colour on the hind wing underside which is typically absent or less extended in similar species. Males have a prominent sex-brand on the upperside of the fore wing. The butterflies are often found resting on exposed branches and leaves where they are easy to observe.
