Scientists Discovered That Butterflies Use A Magnetic Compass for Navigation

75696129 reppert1

The BBC published a story about how monarch butterflies use a magnetic compass for cross-continent migration:

To test for this, the scientists strapped butterflies into a flight simulator, allowing them to point in any direction while flying “on the spot”.

They surrounded the chamber with a magnetic coil system and varied the inclination angle of the field – effectively changing the position of the equator and the poles.

The monarchs responded by turning in the direction they perceived as south.

Crucially – the magnetic compass only worked when the butterflies were also exposed to light in the ultraviolet-A/blue range. This was not present in previous magnetic experiments with monarchs – explaining why they failed to find evidence of such a compass, the researchers believe.

“To our knowledge, this is the first demonstration of the use of an inclination magnetic compass by a long-distance migratory insect,” said Prof Reppert.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
