Here is another photograph of the Dingy Swallowtail. This one had a different colouring. The pictures are not too sharp because the camera is not that great and they usually emerge from the cocoon between midnight and before sunset.
Thanks to "aussietrev" for helping me name my babies.
For 2-3 seasons my orange plant served as a breeding ground for these butterflies to grow. At one there could be as many as 8 caterpillars on my plant.
unfortunately, my plant is no more... :( my cat killed it.
