Josh BryantHOST
Given that we need them to not only be in these numbers, but make it to the alpine regions, do, do we therefore need to be extra careful if we are relocating these moths if they're inside and, and doing as much as we can to, to safely get them at least back outside?

Marissa ParrottGUEST
A female Bogong moth can lay 2,000 eggs and have 2,000 youngsters, so that can really help the population to rebound and recover.

Josh BryantHOST
We'll, we'll get a reprieve if people are getting a bit sick of seeing the Bogong moths after the last few weeks, but the question, uh, I guess on many people's minds is, is this back, uh, to what we've seen in the past? Can we expect them in similar numbers next year, or is it just too soon to tell?

Marissa ParrottGUEST
Well, the Bogong moths are such an amazing species, and this is how nature should be.

Marissa ParrottGUEST
People remember from the past them being in such big numbers that they would block out the stars and the moon as they went overhead, and then their numbers have been lower more recently.

Marissa ParrottGUEST
So seeing their numbers return to such healthy sizes is a real positive for what is an endangered species.

Marissa ParrottGUEST
We're not sure why their numbers are so much better this year, and there are quite a few potential reasons.

Marissa ParrottGUEST
One is that following their collapse of 99.5% in 2017 and 2018, uh, their numbers have been growing every year since then on our Moth Tracker website.

Marissa ParrottGUEST
So hopefully that means that as those numbers grow, they can m- reach that critical mass and become healthy again.

Bogong moth migration reaches record numbers

Marissa ParrottGUEST
Well, they are on their great migration now, heading 1,000 kilometres up to the Alps, and that can take days to weeks.

Marissa ParrottGUEST
It could even be them coming through over the next few months, but they won't stay long.

Marissa ParrottGUEST
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.

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

Marissa ParrottGUEST
Sometimes you see waves across the season, but we don't know exactly what causes their different travel routes, their different timing.

1:35PaulHOST
How many of them are there in this, uh, swarm or migration? Uh, there seem to be several hundred in my house at the moment.

Marissa ParrottGUEST
Well, please take a photo of those, Paul, and log them on our Moth Tracker website because we're trying to work out exactly how many moths there are.

Marissa ParrottGUEST
In the past, around four billion would migrate every year, but back in 2017 and 2018, their numbers collapsed by around 99.5%.

Marissa ParrottGUEST
It was absolutely shocking and terrible not only for the bogong moths but the animals that rely on them up in the alpine zone, like the critically endangered mountain pygmy possums.

Marissa ParrottGUEST
On Moth Tracker, we've seen them increasing each year, and the last two years were the best.

14:42What else do we know about the migration? Where are they headed? Why are they going there?

Marissa ParrottGUEST
Oh, we're so excited to see all of the numbers that are coming through on our website, MothTracker, that everyone's sharing.

Marissa ParrottGUEST
They're flying from their breeding grounds, which are around Southern Queensland through New South Wales, Western Victoria, South Australia even, and they're making this great migration a thousand kilometers up to the Alpine zone, where they will spend their summers in nice cool boulder fields and caves to escape the heat.

Marissa ParrottGUEST
After that, they will then migrate all the way back again in autumn, where they will breed, lay their eggs, and then die.
S
18:57Who knew? Are there any programs happening to try and replenish these numbers? Is there anything we can do in our day-to-day to try and boost the population of bogong moths going forward?

Marissa ParrottGUEST
And every year, particularly across Southeast Australia, although they are found in other states and territories, they will migrate up to 1,000 kilometres from their breeding grounds up to the Alps where they spend the summer.

Laura SpurwayHOST
So you've now got a moth tracker, which I assume is to do with the big, big dip in population of the bogong moths that you saw a few years ago, and you want people to send pictures in.
