In Victoria, specimens are always pink with red or orange spots and a whitish border. They have only been found feeding on the pink aplysillid sponges, Dendrilla rosea and Darwinella cf. gardneri. There is a distinct boundary between the New South Wales and Victorian colour forms at Green Cape on the border between the two states. At Mallacoota, just south of Green Cape, the typical pink form can be very common while at Eden, a few kilometers north of Green Cape, only the white or pink New South Wales form with a yellow border can be found.
