Polyura sempronius the swallowtailed Emperor
Been through all your caterpillar pages and thought you might like this guy from Queensland, Australia. This is the Polyura sempronius, the swallowtailed Emperor. Caterpillar is about 2 inches long and apparently this is the fully mature stage. Hope you like it.
That is one amazing looking caterpillar. We did additional research and located a website that pictures the life cycle of this Brush Footed Butterfly. The caterpillar food plants include species of Acacia known at Wattles.
