green horned caterpillar
Green horned caterpillar Polyura sempronius IMG 5411 - The horns of this distinctive caterpillar give it a fearsome appearance but it is harmless to humans. In the early stages of its life, the caterpillar, which is the larva of the tailed emperor butterfly, is yellow, but its colour changes until it ultimately becomes green. It is found in all mainland states of Australia, but is most commonly seen in sub-tropical and tropical regions of the country. It feeds on the foliage of many native and exotic plants, including several wattles (Acacia species), poinciana trees (Delonix regia), and crepe myrtle (Lagerstroemia indica).
