A small insect, bogong insect, travels 1,000 km every year across Australia every year. These kites abandon the heat of South -East Australia in the spring to relax in cool caves in Australian Alps. They have sexual intercourse in autumn and die.
A new study suggests that these kites use stars to guide them, such as birds and humans. This is the first time such skills have been found in insects.
The bogong insect, which is now threatened, has a feather of about 5 cm. They feel the magnetic field of the Earth, which gives them a backup if the sky is cloud.
Scientists studied about 400 bogong pests to understand how they travel 1,000 km at night. Now, they are surprised how these small and mind organisms manage such complex navigation.
These kites can see 15 times more bright than humans, which can help them to use Milky Way as a guide. Other animals such as monarch butterflies and cow dung beetle also use light for navigation, but not for such a long, accurate journey.
In fact, the special thing is that Bogong insects make this journey only once in their life and learn it from instinct. His parents die before his birth. Nevertheless, they know where to go.
Australian researcher Eric Warrant tested whether they use stars for guidance. He established a special laboratory at his home, near the Moths destination in the Alps.
Using a light mesh, they caught kites and fixed them into thin rods that allowed them to fly while recording their direction. The lab estimated the sky of the southern night, as it looked outside.
Surprisingly, kites flew in the right migrant direction, in the south in the spring and in the north autumn. The experiment revealed how he used a star pattern to guide his own way.
First for wisdom
CNN quoted the warrant as saying, “This is a task of true navigation. They are able to use stars as a compass to find a specific geographical direction to navigate, and this is the first to Akshharuki.”
“With a very small brain, a very small nervous system, they are able to exploit two relatively complex signs and not only detect them, but also use them to use them to go out,” the warrant said.
