Cairns birdwing (male)
This is nice example of a Cairns Birdwing (male) butterfly. Its scientific name is Ornithoptera euphorion and it is found in Australia. Adults live for 4-5 weeks and feed on nectar in the rainforests where they normally live.
In neighboring New Guinea, the Queen Alexandra’s Birdwing is considered to be the largest butterfly. My little guy was taken at Butterfly World.
