Wonder Brown female showing cryptic colouring of undersides, Claire Cottage Dorrigo Plateau, 22 Dec 2008
This butterfly is one of the few where the sexes look completely different.
The dark-coloured female with the white slashes is very hard to see when she lands in the speckled shade of the forest. When she closes her wings on the forest floor her cryptic colouring means she virtually disappears.
The male's showy orange colouring, however, makes him stand out when he perches with his wings open. When he lands on leaf litter and closes his wings, he too is very hard to see.
