Bogong moths could stick around for months but biologist says it’s all a promising sign for nature

It’s the house guest nobody invited, and they’ve certainly brought their friends.

Millions of bogong moths are on the move, with some making themselves right at home in an unexpected pit stop on their annual journey to the Australian Alps.

The unexpected stopover has left many Australians forced to share their homes with the winged creatures, but according to senior conservation biologist at Zoos Victoria, Dr Marissa Parrott, the migration is a good sign for nature.

“We’re seeing wonderful healthy numbers again after lower years,” she said.

She said Zoos Victoria Moth Tracker website has already recorded 12,000 verified sightings.

“That’s about six times higher than our previous best seasons. It’s just wonderful to see the numbers coming back to where they should be and everyone enjoying a visit from an endangered species,” she said.

Parrott said the moths are on their great migration, heading 1000km up to the Alps, which could take days to weeks.

She said they could even persist over the next few months, but they won’t stick around for long.

“They’ll just continue their migration up to those nice, cool caves, to the species that rely on them, like the critically endangered mountain pygmy possums,” she said.

“Enjoy them while they last, while they have a quick feed, and then they will head on by themselves.”

She encouraged Australians to jump on the Moth Tracker website, snap some photos, and upload them to help researchers understand when and where they’re travelling, where they’re running into trouble, and how we can best protect and recover them for the future.
