Monarch butterflies have a keen sense of direction, even on cloudy days. This is because they have a magnetic compass to direct their migration in addition to navigating by the position of the sun ...

When monarch butterflies wing their way south to central Mexico each fall, they use the sun to ensure that they stay on course. But how they head in the right direction on cloudy days has been a ...

Monarch butterflies employ a sun compass on their long-distance migration. Surprisingly, a new study shows that the compass is only established during flight.

A new study suggests that monarch butterflies use an internal magnetic compass to help navigate on their annual migrations from North America to central Mexico.

Researchers have cracked the secret of the internal, genetically encoded compass that millions of monarch butterflies use to determine the direction -- southwest -- they should fly each fall to ...

Reppert says that even though the monarch butterflies use the sun compass to migrate, they also use the magnetic compass as a backup.

A new study suggests that monarch butterflies use an internal magnetic compass to help navigate on their annual 2,000-mile migrations to central Mexico.

Monarch butterflies use the Earth’s magnetic field and a ‘sun compass’ in their antenna as navigational tools for their long-distance migration, scientists say.

Scientists have shown that the annual migration of the monarch butterfly is achieved with just an in-built “compass” – based on the position of the sun – which tells the insect which ...

NEW YORK (AP) — A new study suggests that monarch butterflies use an internal magnetic compass to help navigate on their annual migrations from North America to central Mexico.Scientists alre… ...

To navigate during their long-distance migration, monarch butterflies (Danaus plexippus) use a time-compensated sun compass. The sun compass timing elements reside in light-entrained circadian ...

Researchers have modeled how the monarch butterfly integrates its internal clock with the sun's position in the sky to find the southwestern direction and fly toward it each fall.
