A popular insect of the Australian Wet Tropics, the Ulysses butterfly (Papilio ulysses), has brilliant electric blue upper wings, trimmed in black. It is a large swallowtail species with wingspan of about 10.5 cm (4.1 in), the Ulysses can be seen throughout the region in rainforest and suburban gardens.
The Ulysses caterpillar is thickset, a lovely grass green colour with a banana yellow collar and blue spots. Its favourite food plant is a handsome tree with clusters of small pink flowers growing straight out of the branches. The tree is called the Euodia (Melicope elleryana) and its floral rewards are also the favourite of many birds and flying foxes.
