Did you hear? Millions upon millions of native butterflies have found their way to South-East Queensland for a migration like no other!


This phenomena, which occurs every six to 10 years, has seen millions of Caper White Butterflies migrate from west of the Great Dividing Range to breed.


It is believed that the huge increase of butterflies across this region of Australia is due to the excellent rainfall west of the Great Dividing Range.


Brisbane Butterfly expert Ross Kendall says that if the season is right out west, they can breed up into the millions.


“Last year we didn’t get a big migration but [this year] I think we are seeing more because of good rainfall,” he said.


For many visitors to South-East Queensland, it’s an unforgettable experience to see so many pretty butterflies at every turn. If you’re one of them, you’ve picked the perfect time to go because their arrival is like watching ‘snow drifts’.


There have reports of people seeing 10 or 20 butterflies per minute flying by in areas including Bribie Island and Bundaberg. As part of their migration, butterflies lay 60-100 eggs each on caper bushes and once hatched, the caterpillars can "annihilate" the plants.


And the butterflies will be around for a while. According to experts, you can expect to see them for at least another month or two.

“Undoubtedly there is tens of millions of them currently flying up and down the east coast,” Mr Kendall said.


“Their big migration is usually in late October to early November, and they will continue breeding until the season’s over.”


Mr Kendall said this is not the first time Brisbane had experienced the butterfly phenomena. He recalled that about 10 years ago there was another massive migration and it caught everyone by surprise.


Well…it has this time as well! Have you experienced the butterfly migration?
