Bogong Moths Are First Bugs Known to Use Stars for Long-Distance Travel

Every spring in the Southern Hemisphere, Bogong Moth Migrates 621 miles (1000 kilometers) to 621 miles (1,000 kilometers) to spend their summer in cool caves in the Australian Alps. At the beginning of the regions, they return to their breeding squares and die. Every moth gives his two-way journey only once, so how do you know where?

A researcher in Lund, a researcher in a sensitive biology shows that a team led by David Dreyer, can use the starry sky between Bogong Missions and other means and to walk in the right direction. If this proves that it is true, Dreyer and colleagues, Australia Bogong Moth, “in special geographical destinations (ie north north, north north), in a new job broadcast in the magazine” Nature.

The same researchers in 2018 proposed It reaches directions using Bogong Moth, but also the magnetic area of ​​the earth, using unknown visual signs. In fact, as a mentioned Nature News and Meetings articleSome animals rely on several different navigation methods. To test the role in leading the role in the night sky, the team seized the insects at the beginning of the team migration, and placed the planetaria similar simulator.

“In a flight simulator, we found that with Spring and autumn migration confidence, naturalistic monthly night skies and nullified geomagnetic fields (known magnetic sense), mayon flew in the directions of migration.

As the ancient sailors are approved, the projected positions of the stars make them a safe navigation tool. Nevertheless, scientists documented only a few nounced birds using the star light to find a certain geographical direction before. Dung insects use the stars to travel straightBut they are not nomadic insects – they do not use the star for long-distance travel as birds and Bogong moths.

Analyzing the brain of trust, scientists also responded to the visual-related neurons, and “the moth was directed to a common sky,” said Moths were moved to the south. In other words, their brains look wired to take perfect desires.

However, the parts of the stars of the stars of the civil servants remain a secret, especially the moths can see individual stars. Researchers, most likely moths, the dairy path, zodiac, moon and potential dark features may also be reliable navigation requests.

As a result, research is built in previous investigations of the team by further illuminating the direction of the tool for Bogong Musta. “Our results, Bogong moths use the magnetic field of Wogong moths and the earth to create a strong compass system for long-distance navigation towards a perfect place.

Next time tight Sun activity GPS causes darknessWe will all wish you were Bogong moths.
