Rare butterflies spotted in the Top End
Rare butterflies which had not been seen in Australia for 30 years have been found in the Northern Territory.
The white albatross, asian tiger and northern argus butterflies have been spotted by the CSIRO at the Garig Gunak Barlu National Park on the Cobourg Peninsula, north-east of Darwin.
Entomologist Dr Michael Braby says the Indonesian species have set up breeding populations in the Top End.
He says the discovery shows that many areas are still poorly surveyed and that little is known about butterflies in the territory.
