Dung beetles orient themselves to roll dung in straight lines using which cues?

Dung beetles orient themselves to roll dung in straight lines using which cues?

• A. Stars only
• B. Odor trails
• C. Magnetic fields
• D. Sun, moon, or Milky Way

Answer: (D)

Dung beetles rely on celestial cues as a compass to keep their dung balls rolling in a straight line away from the pile. By using the sun during the day and the moon or the Milky Way at night, they can maintain a consistent heading even if wind or terrain would otherwise push them off course. The Milky Way, in particular, provides a reliable night-time reference for direction. Odor trails help them find dung, but they don’t dictate the straight-line path once they start rolling. Magnetic cues aren’t the primary navigation signal for this behavior.
