Bogong Moths Use Milky Way for 1,000km Navigation
Imagine tiny moths, like little airplanes, flying thousands of kilometers every year!
These moths, called Bogong moths, travel across Australia.
What's amazing is that they use the stars and the Milky Way to find their way, just like birds and people do.
Scientists were surprised to learn this because it's the first time they've seen this in insects.
The moths only do this trip once, and they haven't been taught by anyone, yet they instinctively know where to go.
Scientists used special labs to test this, showing the moths really do use the stars to navigate.
It's like they have a built-in map!
Bogong moths navigate 1,000 km annually using the Milky Way.
Scientists found moths use stars for navigation, a first for insects.
These moths, now endangered, have a wingspan of about 5 cm.
They journey from southeastern Australia to the Australian Alps.
Moths make the journey once, guided by instinct, without parental teaching.
