This Caterpillar is black with a white line along the back and two along each side. It has a brown head with an orange collar, and orange saddles on the last four segments. The caterpillar is missing the first 3 sets of prolegs, so walks in a looper fashion. The caterpillar has been found feeding on

  • Common Wilkiea (Wilkiea huegeliana, MONIMIACEAE).

    The adult moth is noteworthy for its size, being rather large for a Geometrid. It has a wingspan of about 6 cms. It is buff coloured, with a pattern of yellow and black dots. Underneath it is dark grey with pale patches, and in particular a pale patch under the tip of each forewing, which distinguishes it from the related species Bracca rotundata.
