The largest Australian butterfly. They fly high around the treetops. Their flight patterns look like a bird. The males are brilliantly coloured with green and gold. The females are larger with white, black and yellow in their wings. Their thorax and abdomen are red and yellow. The female seems to ‘dance over’ her host plant to check its suitability. Eggs are laid singly on or near the host plant.
