"Each spring, they migrate up to 1000 kilometres to remote #caves in the #AustralianAlps... In a 2018 study, researchers discovered the bogong #moth can sense the Earth’s magnetic field and use it as a guide... It turns out the magnetic field is a backup navigational aid the #moths rely on during cloudy conditions when the stars aren’t visible."

Migrating bogong moths use the stars and Earth’s magnetic field to find ancestral summer caves each year

Australia’s iconic bogong moths are the first creatures other than humans and some birds known to navigate by the night sky.

"When the warmer days of spring spread across the country, billions of #BogongMoths up stakes and fly, unerringly and only at night, up to 1,000 km to a place they have never been before: the cool #caves high in the #AustralianAlps... they use the starry sky without any additional cues to fly in that direction"

Good to see recovery of Bogong moths this year due to triple #LaNina.
Bogong moths migrate to alpine areas in the summer and their sharp population decline by 99.5% due to #drought years imperiled other species survival like the Mountain Pygmy possum. An example of how decline in one species can affect the breeding and decline in another.

Bogong’s back: La Niña rains help moth numbers recover from near extinction

Decimated by relentless drought, the population of the Australian insect is recovering but remains fragile
