專家現在發現，他們可以像指南針或衛星導航一樣利用地球磁場來在旅途中保持航向。

博貢蛾是一種小型蛾類，以澳大利亞土著語中“棕色”一詞命名，每年氣溫升高時，它們就會從澳大利亞東海岸的故鄉飛到澳大利亞阿爾卑斯山內陸涼爽的洞穴中避難。

《自然》雜誌發表的一項研究發現，飛蛾還可以利用星星和銀河系的光在黑暗的天空中導航。

研究還表明，飛蛾可能會利用山間庇護所附近的一種特殊氣味作為旅程終點的導航燈塔。

Scientists have discovered the first known invertebrate that uses the sky for long distance navigation.

A species of Australian moth, called the bogong moth, uses the light from the stars and the Milky Way to find its way through the dark.

Every summer the insects travel more than 600 miles from the east coast of the country to find cooler climates.

Experts have now discovered that they can use the Earth's magnetic field like a compass, or sat nav, to stay on track during their journey.

Until now, only humans and certain species of birds and seals were thought to be able to use starlight to navigate long distances.

Bogong moths, a small species of moth named after the Indigenous Australian word for brown, fly from their home on Australia's eastern coast to the cool inland shelter of caves in the Australian Alps every year when temperatures rise.

A study published in the journal Nature has found that the moths can also use the light from the stars and Milky Way to navigate through the dark skies.

An international team of researchers discovered that these moths can use starlight for navigation, even when artificial maps of the night sky were projected inaccurately.

The research also suggests that the moths may use a specific smell near their mountain shelter as a navigational beacon at the end of their journey.
